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 im...

Embodiment Construction

[0014] The technical solutions of the present invention will be described in further detail below through specific implementation methods.

[0015] like figure 1 , figure 2 and image 3 As shown, a transformer switching monitoring system includes a transformer and a first isolating switch 1, a circuit breaker 3, and a second isolating switch 2 installed in sequence on the output side of the transformer. The entire system uses the first isolating switch 1, The cooperation between the circuit breaker 3 and the second isolating switch 2 performs the switching of the transformer, so as to ensure the correctness of closing and avoid accidents. In order to ensure the accuracy of closing, the transformer switching monitoring system also includes a controller 4 and an alarm circuit. The controller 4 can perform simple cutting and closing commands according to the collected signals by using the existing technology, so that the transformer switching Automatic control and real-time m...

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...
