The permalloy clamp which is a closed type annular clamp is sleeved on the overground part of a cable to be detected. The signal input end of the permalloy clamp is connected with the transmitter. Compared with the prior art, the cable route electrification detection device has the advantages of good detection accuracy and high efficiency, etc.
Description
Technical field
The utility model relates to a kind of cable trace band electric detection device, especially relates to a kind of pahtfinder hard band electric detection device that is applicable to low-voltage cable.
Background technology
Lv power cable is the cable machinery of the minimum rated voltage of system of State Grid Corporation of China.At present, most of lv power cable is in the nerve endings of electrical network, and equipment Management Level distance high-voltage power cable standardized management gap is larger.Be in particular in the following aspects:
1, list inconsistent phenomenon ratio of equipment near-end cable termination and distance terminal is high.The situation of confusing cable according to the existing nameplate of equipment happens occasionally, and the inaccurate ratio of equipment nameplate of especially same bus double cable is higher.
2, the ratio of cable machinery path profile disappearance is high.Because low pressure 380V number of cables is various, possessing Pyatyi, to take up the unit of construction quality many, and electric company's span of management is excessive, and run unit is considerably less with the equipment ratio of complete cable trace figure during the low-voltage cable asset handover.
3, the ratio of cable machinery joint location figure disappearance is high.Cable splice is the weakest link of cable system, and the cable splice location drawing is the pacing items of quick pinpoint low-voltage cable fault.Because the attention degree to low-voltage cable equipment was not high in the past, run unit is not strict to the management expectancy of low-voltage cable as-constructed drawing and the cable splice location drawing, forms actual disappearance, consists of very large obstruction to cable trace generaI investigation and cable fault location.
Because the Underground Pipeline Archives data is inaccurate, incomplete, imperfect, discrete, form is various, the data standard disunity, cause information to utilize difficulty, degree of share low, even cause the engineering accident phenomenon to happen occasionally, how improving underground pipeline information quality of achievement monitoring security mechanism is one of the outstanding problem that need to solve as early as possible.During existing Underground Pipeline General Survey was surveyed, because the factor such as complex geologic conditions, environmental difference are large, a large amount of uses of non-metal pipe and the large buried pipeline of non-excavation increase gradually, the accuracy and efficiency of detection had much room for improvement.
The utility model content
The purpose of this utility model is exactly to provide the cable trace band that a kind of detection accuracy is good, efficient is high electric detection device for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of cable trace band electric detection device, comprise transmitter for generation of detectable signal, be used for receiving receiver and the permalloy clamp of detectable signal, described permalloy clamp is the annular clamp of closed type, be set in the aerial part of cable under test, the signal input part of permalloy clamp connects transmitter.
Described transmitter is provided with a plurality of detectable signal output terminals, and each signal output part has been connected respectively a permalloy clamp, detectable signal is induced in the stratum at cable under test under ground portion place.
Each detectable signal output terminal correspondence is signal generating circuit independently, produces the detectable signal of different frequency.
Also be provided with wireless communication module on the described transmitter and receiver, by this wireless communication module the real-time condition of detection process uploaded.
Compared with prior art, the utlity model has following advantage:
1, adopts the closed permalloy clamp of annular, detectable signal is induced in the cable under test, make its single core cable that more is applicable to low pressure, and the investigation depth of cable trace is considerably beyond common clamp.
2, transmitter can be exported the detectable signal of a plurality of different frequencies simultaneously, and multiway cable is surveyed simultaneously, can improve the efficient of detection.
3, can upload fast the real-time condition of detection process by wireless communication module, can grasp at any time to survey with the personnel that conveniently are positioned at remote monitoring center and carry out, obtain result of detection.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of cable trace band electric detection device comprises transmitter 1, receiver 2 and permalloy clamp 3.Wherein, transmitter 1 is used for producing detectable signal, permalloy clamp 3 adopts the annular clamp of closed type, be set in the aerial part of cable under test 4, the signal input part of permalloy clamp 3 connects the signal output part of transmitter 1, receive the detectable signal that produces, and with induction of signal to the stratum at cable under test 4 under ground portion places, because permalloy has very high low-intensity magnetic field magnetoconductivity, and adopt the loop configuration of complete closure form, can well detectable signal be induced to the stratum at cable under test under ground portion place, so that receiver 2 can receive faradic secondary magnetic field signal in the cable under test preferably, carry out the accurate location of cable trace, its locating effect is compared with common clamp, have obvious advantage, specifically as shown in table 1.
Table 1
In order to improve the efficient of detection, transmitter 1 is provided with a plurality of detectable signal output terminals, and correspondence signal generating circuit independently, can produce the detectable signal of different frequency.Be connected respectively a permalloy clamp 3 at each signal output part, carried out simultaneously multiplexed detection.In addition, on transmitter 1 and receiver 2, wireless communication module 5 is set also, by this wireless communication module the real-time condition of detection process is uploaded, can grasp at any time to survey with the personnel that conveniently are positioned at remote monitoring center and carry out, obtain result of detection.
