An Unattended Circuit Breaker Monitoring and Prevention System

Abstract

The invention discloses a monitoring precaution system for an unattended breaker. The system comprises a breaker body. The breaker body is electrically connected to a main transformer circuit of a transformer substation. The system further comprises a controller and a wireless mobile phone terminal. The controller is installed on the breaker body and is wirelessly connected to the wireless mobile phone terminal. The system also comprises an intelligent lift protective cover. The intelligent lift protective cover encircles the breaker body. The breaker body is provided with a plurality of photoreceptors. The photoreceptors and the intelligent lift protective cover are in wireless connection with the controller. The breaker body is also provided with a busbar wireless temperature measuring device. The busbar wireless temperature measuring device is in wireless connection with the controller, and is equipped with a first-level warning part and a second-level warning part. The first-level warning part can control the controller to emit alarming signals, and the second-level warning part can control the controller to cut off the main transformer circuit.

Description

technical field [0001] The invention relates to a monitoring and preventing system for a substation, in particular to a monitoring and preventing system for an unattended circuit breaker. Background technique [0002] At present, the circuit breaker is used as a device to control the switching operation of the circuit, and it is widely used in substations. Due to the lack of monitoring and protection for the circuit breaker in the existing substation, the circuit breaker will be damaged due to high temperature, high humidity and other reasons after a long period of use. A fault occurs, which affects the service life of the circuit breaker and causes problems in the circuit of the substation; [0003] Moreover, the voltage of the substation is relatively high. When the high-voltage current passes through the circuit breaker, it will cause the contact of the circuit breaker to heat up, and when the circuit breaker is disconnected, an arc will be generated.

Problems solved by technology

[0002] At present, the circuit breaker is used as a device to control the switching operation of the circuit, and it is widely used in substations. Due to the lack of monitoring and protection for the circuit breaker in the existing substation, the circuit breaker will be damaged due to high temperature, high humidity and other reasons after a long period of use. A fault occurs, which affects the service life of the circuit breaker and causes problems in the circuit of the substation;

[0003] Moreover, the voltage of the substation is relatively high. When the high-voltage current passes through the circuit breaker, it will cause the contact of the circuit breaker to heat up, and when the circuit breaker is disconnected, an arc will be generated. When the arc contacts the overheated contact, it will cause Explosion, a considerable safety hazard;

[0004] Usually the staff will monitor the substation, but this kind of monitoring requires someone to stare at the monitor all the time. After a long time, the staff will be tired, prone to negligence, causing unnecessary troubles, not only wasting manpower, but also relatively low efficiency
