Description

[0001] The present invention relates to a connector having a power measurement module, and a connector having a sensor module and a distributing board using the connector.

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a connection connector having a power measurement module capable of improving a binding method of a main breaker and a branch breaker coupled to a distribution board and preventing a safety accident, and a distribution board using the same.

Currently, various devices for monitoring the power consumption of the distribution board are being developed in Korea. The voltage, current, and other information of the distribution board are measured using a sensor located outside the distribution board, and the measurement results are displayed on the front surface of the enclosure It is common to follow. Since the current measurement must precede the power related information measurement, the current measurement device and the current measurement method for the current measurement are essential devices. Examples of the current measuring method include a method using a shunt resistor, an insulating type measuring method using a current transformer CT, and a method using a magnetic sensor (Hall sensor, etc.). When a shunt resistor (classifier) or a magnetic sensor is used, there is a problem that it is difficult to use in a high voltage or a large current. Therefore, a current transformer (CT) or a transformer (PT) is used for high voltage or large current, and power or current is measured for low voltage and low current in the subsequent stage.

The method using a current transformer uses electromagnetic induction phenomenon, and it is easy to ensure comparatively high precision. However, when the current is large, CT is saturated. In the case of a large current, the weight is heavy and occupies a large space . An example of a method of measuring an electric current by an electromagnetic induction method includes a method using a Rogowski coil (see Patent Application No. 10-2009-0066951).

In accordance with the electromagnetic induction method, the influence of the magnetic field (adjacent current interference) derived from the current flowing in the adjacent wire or bus bar can be received. Such interference is not a problem in a general case, but a current transformer is installed in a situation where a product requiring precision, a large current such as extra high voltage / high voltage flows, or a booster bar or a wire bundle, A considerable error is caused in the current amount measurement. Especially, in case where a bus bar connected to a high power load such as an ASSEMBLY is densely packed, if a Hall sensor or a Rogowski coil is used, the interference amount from the adjacent current reaches 10% there is a problem. In order to eliminate such interference, a method of shielding the influence of an external magnetic field has been studied, but this is also difficult in a narrow space such as a distribution board.

Therefore, it is urgent to develop a power measuring device capable of being applied in a narrow space with little interference or error, and capable of being remodeled even in a live state.

The present invention relates to an electric power measuring module which facilitates connection between a main breaker and a branch breaker, prevents a bus bar from being exposed between them, and more particularly, And a power distribution module using the same.

In order to solve the above-mentioned problems, the present invention is characterized in that a slot part in which a plurality of phases are arranged in the vertical direction so that the bus bar bars connected to each other from the main breaker and stacked in the vertical direction can be simultaneously coupled to one side, And a coupling portion coupled to the branch circuit breaker, the charger bus bar being disposed on the other side of the main body and connected to the main line bus bar, and a power measuring module coupled to the housing detachably and measuring power, And the power measuring module is slidingly coupled with the power measuring module.

The housing or the power measuring module is provided with a protruding member protruding outward along the direction in which the housing and the power measuring module are coupled to each other. The protruding member is inserted into the housing of the housing or the power measuring module And may include guide grooves formed therein.

The power measurement module includes a sensor unit for measuring power by contacting or non-contacting the charger bus bar exposed on the housing, a communication unit for transmitting data measured by the sensor unit to the outside, And a cover portion coupled to the main body portion and slidably coupled with the main body portion on the housing and selectively opening and closing the upper portion of the main body portion.

The cover unit may include at least one LED unit that lights up to visually confirm the current state of the charger booth bar.

The power measurement module can be attached and detached even when the main bus bar is in a live state.

The present invention also relates to a plasma display panel comprising a main breaker to which a plurality of bus bar bars stacked in a vertical direction are connected; And a branch circuit breaker coupled to the main line bus bar at one side thereof so as to be coupled to the main line bus bar at one side thereof and to be connected to the charger bus bar at the other side of the connection connector, A distribution board using a connector is provided.

The main breaker may include a bus bar insulator for connecting the bus bar bars in a state where the connection terminals are arranged in a horizontal direction and are stacked in a vertical direction.

According to the connection connector having the power measurement module according to the present invention and the distribution board using the same,

First, since the main bus bar connected to the main breaker has a vertically stacked structure, the spatial efficiency is increased compared to a structure in which the main bus bar is arranged in the horizontal direction,

Second, the connection connectors are coupled in a slot structure to the stacked bus bars,

Third, since the bus bar is not exposed to the outside between the connection connector and the bus bar bus bar, it is possible to prevent a safety accident or a fire accident in advance,

Fourth, since the connecting connector is the inverse of the charger bus bar, the wiring method is simplified, the number of manufacturing processes is shortened,

Fifth, since the power measuring module is integrally formed in the connection connector and detachable, the maintenance can be performed even in the live state,

Sixth, the space required for wiring between the main circuit breaker and the branch circuit breaker is greatly reduced through the connection connector, and the overall size of the distribution board can be reduced.

In the main breaker 110, a plurality of connection terminals electrically connected to the connection connector 1000 are arranged in parallel in the horizontal direction. A bus bar support insulator 111 is provided at a connection terminal of the main breaker 110 to connect the bus bar bar 10 to a vertically stacked structure. Therefore, the present invention is also applicable to the main breaker 110 generally used. Of course, the main breaker 110 and the bus bar support insulator 111 may be integrally formed so that the connection terminals are vertically formed. At this time, the bus bar bar 10 is arranged with four phases along the vertical direction, and for example, the R, S, T, and N phases can be sequentially stacked while maintaining the spacing distance.

At this time, the bus bar bars 10 are coupled to the slots 1110 in a stacked structure in a vertical direction. Also, as shown in FIG. 1, since the connection connector is coupled to both sides of the busbar 10, the busbar 10 is not exposed to the outside in the connection connector portion.

As shown in FIG. 3, the housing 1100 has a slot portion 1110 on one side and a coupling portion 1120 on the other side. The coupling part 1120 is installed inside the charger bus bar 20 and the bus bar bar 10 and the charger bus bar 20 are connected to each other while the bus bar bar 10 is fastened to the slot part 1110. [ Respectively.

As shown in FIGS. 4 and 5, the power measurement module 1200 is slidingly coupled to the coupling portion 1120.

The housing 1100 and the power measuring module 1200 are provided with a protruding member 1210 protruding outward along the direction in which the housing 1100 and the power measuring module 1200 are coupled to each other, A guide groove 1121 is formed so as to be inserted into the protrusion member 1210 so as to be slidably engaged.

More preferably, the protrusion member 1210 is provided on the power measurement module 1200, and the guide groove 1121 is formed on the housing 1100 to be slidingly coupled with each other.

The power measurement module 1200 is slidably coupled to the coupling portion 1120 and is brought into contact with the lower surface of the charger booth bar 20, thereby acquiring data such as current, voltage, and temperature.

The protruding member 1210 includes a sliding member 1211 guided in the guide groove 1121 to engage the power measurement module 1200 and a cover member 1212 further projected from the sliding member. A detailed description thereof will be later.

When the power measurement module 1200 is coupled to the coupling portion 1120, the charger booth bar 20 is partially exposed to the outside, which is coupled to the branch breaker 120 and is not exposed again.

The sensor unit 1220 may be a magnetic sensor. The magnetic sensor has either an electromagnetic induction type in which a coil is installed and a Faraday's law is applied to an electromagnetic induction effect, or a current magnetism effect type in which a rotating element is applied using a compound semiconductor. More preferably, the Hall sensor 1221 may be a Hall effect sensor of the current magnetic effect type. It is characterized in that the direction and magnitude of the magnetic field can be determined by using Hall effect, in which a magnetic field is applied to a conductor through which current flows and a voltage is generated in a direction perpendicular to the magnetic field.

The Hall sensor 1221 can measure current by removing interference of adjacent currents. In order to eliminate the interference of the adjacent currents, a plurality of power measurement modules 1200 provided in insulation contact or adjacent to a plurality of circuits measure and output the current flowing through the corresponding circuits, collect the output signals, It is possible to derive the correction current value from which the interference is removed by calculating the interference amount between a plurality of circuits in the measurement signal.

At this time, the process of measuring the current flowing through the corresponding circuit through the power measurement module can measure the current flowing through the corresponding circuit according to the insulation type using a current transformer (CT). Also, the step of deriving the correction current value from which the interference is removed by calculating the interference amount generates the interference coefficient matrix, derives the interference coefficient for the circuit using the generated interference coefficient matrix or the interpolation method, The correction current value can be derived using the interference coefficient. Herein, the interference coefficient matrix may generate a plurality of units of one or more variables selected from the group including the temperature, the amount of current, and the distance between the current measurement position and the circuits within a predetermined range.

Also, the bottom surface is partially opened so that the sensor unit 1220 and the charger bus bar 20 can be in contact with each other. The sliding member 1211 and the cover member 1212 are formed on one side and the main body 1240 is fixed on the housing 1100 by a fastener from the upper surface of the cover member 1212. At this time, the main body 1240 or the cover member 1212 is formed of an insulating material, and there is no problem in attaching and detaching the main body 1240 or the cover member 1212 in a live state.

The cover 1250 covers the upper portion of the main body 1240 and is coupled to the guide groove 1121 by extending the sliding member 1211 and the cover 1212 is engaged with the main body 1240.

Further, the sliding member 1211 may be formed longer than the cover member 1212, so that the coupling force of the power measurement module 1200 can be more firmly maintained.

The cover part 1250 includes an LED part 1251 which lights up so that the state of energization of the charger booth bar 20 can be visually confirmed. For example, each of the LEDs 1251 may be configured to be turned on or off to indicate a state set by the respective lighting or blinking display. Of course, they can also be lit or flashing to display different colors.

The LED unit 1251 may display the state of the branch circuit breaker 120 based on data received from the sensor unit 1220.
