Transformer switching monitoring system

Abstract

The present invention provides a transformer switching monitoring system. The transformer switching monitoring system comprises a transformer, a first disconnector, a circuit breaker, a second disconnector, a controller and an alarm circuit; the disconnector includes a base as well as a moving contact, a fixed contact and a disconnecting link which are all mounted on the base; one end of the disconnecting link is hinged to the moving contact, and the other end of the disconnecting link is provided with a conductive sheet; the base is provided with a switching-on indication light loop corresponding to the conductive sheet; the controller is connected with the switching-on indication light loop and a current collecting circuit mounted on the output side of the transformer; the controller drives the tripping mechanism of the circuit breaker according to collected disconnector switching-on information and transformer output current information; and the controller is connected with the alarm circuit and judges whether an alarm is to be given according to collected circuit breaker tripping information. The transformer switching monitoring system has the advantages of scientific design, high practicality, good monitoring effect, convenient operation and high safety.

Description

technical field [0001] The invention relates to a transformer switching monitoring system, in particular to a transformer switching monitoring system for safe switching. Background technique [0002] As an important part of the transmission line, the transformer's operation quality determines the power supply quality of the entire transmission line, so the switching of the transformer is very important. Most of the existing transformers are switched on and off with the transmission line through isolating switches, circuit breakers, etc. When switching, most of the isolating switches, circuit breakers, etc. are manually checked to see if they are in place, and there is no real-time monitoring of the current on both sides of the transformer when they are put into operation, so it is impossible to Ensure that the working status of each isolating switch and circuit breaker is monitored during switching, and at the same time, there is no monitoring of the current of the transmiss...

Problems solved by technology

Most of the existing transformers are switched on and off with the transmission line through isolating switches, circuit breakers, etc. When switching, most of the isolating switches, circuit breakers, etc. are manually checked to see if they are in place, and there is no real-time monitoring of the current on both sides of the transformer when they are put into operation, so it is impossible to Ensure the monitoring of the working status of each isolating switch and circuit breaker during switching, and at the same time lack of monitoring of the current of the transmission line

Due to the uncertain factors of transformer switching, the power supply quality of transmission lines cannot be guaranteed, and it cannot meet people's requirements for high-quality power supply.
