Electrical performance detection device for pole-mounted circuit breaker controller

Abstract

The invention discloses an electrical performance detection device for a pole-mounted circuit breaker controller. The device comprises a terminal strip, a pole-mounted circuit breaker controller aviation plug, an energy storage relay coil, a switching-on relay coil and a switching-off relay coil, wherein the pole-mounted circuit breaker controller aviation plug is electrically coupled with the terminal strip, and one side of terminal strip is electrically coupled with a first power supply and a second power supply. According to the invention, the remote signaling function of the pole-mounted circuit breaker controller is ensured to be normal by setting closing, tripping, energy storage and non-energy-storage state signal indication, voltage and current signals are input through the terminal strip, the remote measurement and protection functions of the pole-mounted circuit breaker controller are ensured to be normal, the electrical performance of the pole-mounted circuit breaker controller can be accurately detected without power failure, early prevention, early discovery and early processing are realized, the power supply reliability of a power grid is improved, the investment costis low, the detection effect is obvious, and the quality of the pole-mounted circuit breaker controller can be clearly and definitely judged.

Description

technical field [0001] The invention relates to the technical field of electrical detection, in particular to an electrical performance detection device for a pole-mounted circuit breaker controller. Background technique [0002] When a fault occurs inside the user connected to the 10kV overhead distribution line T, if the fault occurs in the incoming line section, or if the fault occurs inside the user incoming line switch but its protection action time limit is not coordinated with the protection of the substation outgoing line switch, it will cause the substation outgoing line Switch protection tripped. If the nature of the fault is permanent and the reclosing of the substation is unsuccessful, an accident in the medium-voltage user community will cause a power outage of the entire distribution line. This kind of spillover accident that is common in the distribution network will have a bad impact on society. [0003] The user demarcation switch is an ideal device to solv...

AI Technical Summary

Problems solved by technology

During normal operation and maintenance, the three remote functions and protection functions of the controller cannot be detected, and the on-site personnel cannot accurately judge the health status and operation status of the electrical performance of the circuit breaker controller (FTU) on the column, and there is a great technical safety hazard , which is not conducive to the safe operation of the power grid
