At present, most of electrical equipment in a transformer substation is located in a secondary equipment screen cabinet and protected by the screen cabinet. However, the electrical equipment is susceptible to high temperature or high voltage during operation, and the ac terminals located on the electrical equipment are partially discharged at high temperature or high voltage, resulting in failure of the electrical equipment.
Accordingly, in order to protect the operation safety of the electrical equipment, it is necessary to detect the state of the ac terminal on the electrical equipment. However, the electrical equipment is usually disposed in a cabinet, which makes it difficult to remotely monitor the status information of the ac terminals of the electrical equipment. Therefore, the state of the ac terminal needs to be detected regularly by the maintenance personnel of the substation.
However, with the strengthening of the grid, the number of electrical devices in the substation increases dramatically. When facing numerous electrical equipment, operation and maintenance personnel can not realize the high-quality and dead-angle-free state detection of the alternating current terminal of each electrical equipment, and the detection efficiency of manual detection is low, and the alternating current terminal with faults can not be found in time.
Based on this, in order to improve the efficiency of detecting the state of the ac terminal, the embodiments of the present application provide a state detection method of an ac terminal, which may be applied to a state detection device of an ac terminal. For example, the state detection device may be a device that can be used for data processing.
Wherein, the alternating current terminal is positioned on the electrical equipment in the box body. The box body can be the secondary equipment cabinet already described. The screen cabinet can be a transparent screen cabinet, so that operation and maintenance personnel can observe the electrical equipment in the box body without opening the screen cabinet conveniently; the cabinet may be a non-transparent cabinet, which is not limited to this.
The electrical device may be a secondary device in a substation, for example, a secondary device such as an electrical instrument, a relay, or an automatic control device, which is not limited herein.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a status detection system according to an embodiment of the present application. The state detection system 100 includes an ac terminal (not shown), a case 110, an electrical device 120, and a state detection device 130. The ac terminal is located on the electrical device 120, the electrical device 120 is located in the case 110, and the electrical device 120 is connected to the state detection device 130. The state detection means 130 is used to perform the various steps in the subsequent method embodiments.
Referring to fig. 2, fig. 2 is a flowchart illustrating an implementation of a method for detecting a state of an ac terminal according to an embodiment of the present application, where the method includes the following steps:
s201, acquiring the temperature of the alternating current terminal acquired by the temperature measuring device in the box body.
In the application, above-mentioned temperature measuring device can be infrared temperature measuring instrument, and it sets up inside the box, and this temperature measuring device's quantity can be one, also can be a plurality of, all can be used for detecting the temperature of interchange terminal. When the number of the temperature measuring devices is plural, the average value of the temperatures collected by the plurality of temperature measuring devices may be determined as the temperature of the ac terminal at the present time.
In another embodiment, the temperature measuring device may also detect the overall internal temperature of the box body or the temperature of the electrical equipment during operation, which is not limited.
The temperature measuring device can acquire the temperature of the alternating current terminal in real time, and then the state detecting device acquires the temperature from the temperature measuring device in real time or at intervals of preset time in a wired or wireless data connection mode. The preset duration can be set by operation and maintenance personnel according to actual conditions, and is not limited.
In another embodiment, the state detection device can also obtain the temperature collected by the temperature measurement device according to a temperature acquisition instruction input by an operation and maintenance worker.
The alternating current terminal can be a wiring terminal connected with a conducting wire conducting alternating current on the electrical equipment.
S202, acquiring an image which is acquired by an image acquisition device in the box and contains an alternating current terminal.
In application, the image acquisition device is used for acquiring an image containing an alternating current terminal. The image acquisition device can be a visible light shooting device. For example, the image capturing device may be a high-definition infrared camera, and the number of the image capturing devices may be one or more, which is not limited herein.
In order to accurately detect the first operating state of the ac terminal, a panoramic image of the ac terminal needs to be acquired when acquiring an image. Namely, shooting the alternating current terminal without dead angles. Therefore, after the position of the alternating current terminal on the electrical equipment is determined, the image acquisition devices can be respectively arranged on two sides of a screen cabinet door on the screen cabinet, and the height of the image acquisition devices is flush with that of the alternating current terminal. Therefore, no dead angle monitoring of the alternating current terminal in the screen cabinet is realized.
In application, the time length (real-time or every preset time length) for the image acquisition device to acquire the image of the alternating current terminal and the connection mode between the image acquisition device and the state detection device can be consistent with the temperature measurement device, which is not described in detail.
S203, determining a first working state of the alternating current terminal according to the temperature and the image.
In application, the first working state includes a normal state or an abnormal state. Specifically, the state detection device can identify the opening and closing state of the terminal connecting piece of the alternating current terminal in the image; then, if the on-off state is a connection state and the temperature is within a preset working temperature range, determining that the first working state is a normal state; and if the on-off state is the separation state and/or the temperature is not in the working temperature range, determining that the first working state is the abnormal state.
Wherein, the terminal is the connection piece on the terminal of exchanging, and this connection piece can be used to other binding post of short circuit. Generally, when the first operating state of the ac terminal is a normal state, the connection and disconnection state of the terminal connecting piece in the ac terminal should be a connection state, and when the electrical device operates, the temperature at the ac terminal should be within a preset operating temperature range. Otherwise, if the on-off state of the terminal connecting piece is in the separation state, the AC terminal is indicated to have a fault; or when the electrical equipment works, the temperature at the alternating current terminal is not in the preset working temperature range, and the potential safety hazard of the alternating current terminal is indicated. That is, although the terminal connecting piece is not separated when the image recognition is performed, the operation at a high temperature still has a safety hazard.
In application, the state of the connection and disconnection of the terminal connecting piece of the alternating current terminal in the identification image may be: and determining the image after performing characteristic processing on the image according to a pre-trained image recognition model. In this embodiment, the training method of the image recognition model is not limited.
And S204, if the first working state is an abnormal state, sending alarm information to a preset terminal.
In application, the preset terminal may be a terminal for displaying or monitoring the first operating state of each ac terminal, or may be a scheduling terminal. The scheduling terminal is used for providing data support for the high-level software application of regulation, control, operation and maintenance.
It can be understood that, because the operation and maintenance personnel are usually located in the monitoring room for monitoring, the alarm information can be timely found by the operation and maintenance personnel after being sent to the preset terminal.
The alarm information includes, but is not limited to, a unique identification number of the alternating current terminal, a position of the alternating current terminal, and a video picture containing the alternating current terminal, so as to assist operation and maintenance personnel to quickly troubleshoot faults. In this embodiment, specific information included in the warning information is not limited at all.
In this embodiment, after the temperature of the ac terminal collected by the temperature measuring device in the box and the image containing the ac terminal collected by the image collecting device in the box are obtained, the first operating state of the ac terminal is comprehensively determined according to the temperature and the image, and the accuracy of detecting the operating state of the ac terminal can be improved. And then, when the first working state is determined to be an abnormal state, sending alarm information to a preset terminal, and timely alarming the alternating current terminal with the fault. Therefore, early warning can be given out at the initial stage of the fault, and the fault can be eliminated in time.
The above embodiment is only one example of determining the state of the ac terminal, and in another embodiment, a protection device and a measurement and control device are further arranged in the box body; referring to fig. 3, the state detection means may also determine the state of the ac terminal according to S301 to S303 as shown in fig. 3. The details are as follows:
s301, acquiring first analog quantity information of the electrical equipment during working, wherein the first analog quantity information is acquired by the protection device.
S302, first measurement quantity information acquired by the measurement and control device during working of the electrical equipment is acquired.
And S303, determining a target working state of the alternating current terminal according to the first analog quantity information, the first measurement quantity information and the first working state.
In an application, the protection device may be a relay protection device, which includes a device for protecting a bus, a transformer, a ground transformer, a station transformer, or the like, and is not limited thereto. The first analog quantity information includes, but is not limited to, information including electrical parameters, such as phase voltage, line voltage, zero sequence current, active power, reactive power, power factor, and frequency, and is not limited thereto.
In application, the measurement and control device may be a device for measuring various electrical parameters of the electrical equipment during operation and controlling the electrical equipment. Specifically, according to the accurate definition of the technical specification of the measurement and control device of the transformer substation DL/T1512-2016 in the power industry standard: the utility model provides a transformer substation automation system interlayer intelligent electronic equipment for realize primary equipment, secondary equipment information acquisition and processing and information transmission, receive control command, realize the control to controlled object.
According to the definition of the measurement and control device, the measurement and control device can also collect information of the electrical equipment (primary equipment and secondary equipment), and therefore, the collected first measurement quantity information also comprises information corresponding to the various electrical parameters. That is, for the same electrical device, the same type of electrical parameter should be consistent in the first analog quantity information and the first measurement quantity information.
Based on this, the state detection device can further determine the target operating state of the ac terminal based on the first analog quantity information, the first measurement quantity information, and the first operating state.
Specifically, if the first working state is a normal state and the first analog quantity information or the first measurement quantity information is null, it is determined that the target working state is an abnormal state.
It can be understood that, when the first operating condition of the ac terminal is a normal condition, that is, the ac terminal is operating normally, at this time, the protection device can acquire the first analog quantity information of the electrical device during operation, and the measurement and control device can acquire the first measurement quantity information of the electrical device during operation.
However, if the first operating state is the normal state, but the first analog quantity information or the first measurement quantity information is empty, it indicates that it may be determined that there is an error in the determination of the first operating state of the ac terminal when the first operating state of the ac terminal is determined from the temperature and the image in S203 described above.
For example, the temperature is within the preset operating temperature range, but actually the terminal link of the ac terminal is in a separated state, but the separation of the terminal link is not obvious, so that the state detection apparatus erroneously determines that the terminal link is in a connected state at this time when recognizing the image.
Therefore, in this embodiment, when determining that the first operating state is the normal state, the state detection device may further determine the target operating state of the ac terminal according to whether the first analog quantity information or the first measurement quantity information is empty, so as to improve the accuracy of detecting the target operating state of the ac terminal.
Based on the above description, it can be known that when the first working state of the ac terminal is the normal state, the protection device can acquire the first analog quantity information of the electrical device during working, and the measurement and control device can acquire the first measurement quantity information of the electrical device during working. Therefore, when the first operating state is a normal state and the first analog quantity information or the first measurement quantity information is not empty, the state detection device may also determine the target operating state according to the first analog quantity information and the first measurement quantity information.
Specifically, the measurement and control device and the protection device are used for collecting all electrical parameters of the same electrical equipment. Therefore, the same type of electrical parameter should be consistent in the first analog quantity information and the first measurement quantity information thereof. That is, it can be considered that when the first analog quantity information is consistent with the first measurement quantity information, the target working state can be determined to be a normal state; and when the first analog quantity information is inconsistent with the first measurement quantity information, determining that the target working state is an abnormal state.
In another embodiment, in order to variously detect the target operating state of the ac terminal to improve the detection accuracy, referring to fig. 4, the state detecting device may also determine the state of the ac terminal according to S401-S404 as shown in fig. 4. The details are as follows:
s401, acquiring a second working state of the alternating current terminal at the target historical moment.
In an application, the target historical time may be a time separated from the current time by one week, one month, or one year, which is not limited. The second operating state is an operating state of the ac terminal determined by the state detection device based on the temperature and the image at the target history time.
S402, second analog quantity information of the electrical equipment collected by the protection device at the target historical time is obtained.
And S403, acquiring second measurement quantity information of the electrical equipment acquired by the measurement and control device at the target historical time.
In application, the second analog quantity information and the second measurement quantity information are similar to the first analog quantity information and the first measurement quantity information, respectively, and only differ in the acquisition time, and thus the description thereof is omitted.
S404, determining the target working state of the alternating current terminal according to the second working state, the second analog quantity information, the second measurement quantity information, the first analog quantity information, the first measurement quantity information and the first working state.
In application, because the first working state and the second working state both describe the working state of the same alternating current terminal, the second analog quantity information and the second measurement quantity information are obtained by carrying out information acquisition on the same electrical equipment. Therefore, the first operating state and the second operating state should coincide, the first analog quantity information should coincide with the second analog quantity information, and the first measurement quantity information should coincide with the second measurement quantity information.
It can be understood that, if the above information are all consistent, the target operating state may be determined to be a normal state. Otherwise, if any one of the above information is inconsistent, it may be determined that the ac terminal may fail between the target historical time and the current time. That is, the target operating state of the ac terminal can be determined to be an abnormal state.
It should be noted that the steps S401 to S404 may be combined with the steps S301 to S303 to comprehensively determine the target operating state of the ac terminal, so as to improve the accuracy of detecting the target operating state of the ac terminal.

Specifically, the data receiving terminal can be set according to the distance between the integral monitoring room and the electric equipment on site. For example, if the distance between the overall monitoring room and the electrical device is greater than a preset distance, the data receiving terminal may be arranged in a sub-monitoring room of the substation; if the distance between the overall monitoring room and the electrical equipment is smaller than or equal to the preset distance, the data receiving terminal can be arranged in the overall monitoring room of the transformer substation. The preset distance can be set according to actual conditions, and is not limited.
In application, the central switch is used for communicating with each electrical device (primary device or secondary device) in the substation to acquire first analog quantity information sent by a protection device in a corresponding screen cabinet and first measurement quantity information sent by a measurement and control device in the corresponding screen cabinet, and forwarding the first analog quantity information and the first measurement quantity information to the state detection device. The protection device, the measurement and control device, the first analog quantity information, and the first measurement quantity information are explained above, and will not be described again.
The state detection device is configured to acquire data (temperature, image, first analog quantity information, and first measurement quantity information) uploaded by the data receiving terminal and the central switch, and perform the state detection method of the ac terminal in each of the above embodiments on the data.
In another embodiment, when it is determined that the ac terminal is in an abnormal state, the state detection device may further send the abnormal state of the ac terminal and the alarm signal to the preset terminal through the DL/T860 protocol. For example, the preset terminal may be a monitoring background or a scheduling terminal, and provide data support for an application on the monitoring background or the scheduling terminal.
