A high-voltage breaker opening-closing control apparatus

Abstract

Provided is a high-voltage breaker opening-closing control apparatus mainly composed of a DC control power switch used for controlling breaker DC control power output, a DC control power voltage change-over switch, an opening-closing signal output switch, an opening-closing signal output port, and a secondary adapter. The DC control power switch is connected with the DC control power voltage change-over switch so as to achieve switching of DC control power 220V and 110V voltage. The opening-closing signal output switch comprises a closing signal output switch and an opening signal output switch. The DC control power voltage change-over switch is connected with the closing signal output switch and the opening signal output switch so as to control opening signals and closing signals. The high-voltage breaker opening-closing control apparatus has characteristics of simple structure, easy manipulation, and good universality.

Description

technical field [0001] The invention relates to an opening and closing control device for a high-voltage circuit breaker, which belongs to the field of electric equipment tools. Background technique [0002] The high-voltage circuit breaker test is an important item in the maintenance test of the high-voltage circuit breaker, and it is an important index for accurately judging the overall performance of the circuit breaker. When the circuit breaker is in the maintenance state, the secondary plug-in of the circuit breaker is unplugged, the circuit breaker loses the opening and closing control power supply, and the working state of the circuit breaker cannot be simulated, which brings inconvenience to the detection test of the circuit breaker. In the traditional detection test process, it is necessary to provide an opening and closing signal for the high-voltage circuit breaker by clamping the clip on the corresponding switch opening and closing pin of the secondary plug-i...

AI Technical Summary

Problems solved by technology

Due to the large number of pins on the aviation plug of the circuit breaker and the small distance between them, the clips on it are easy to contact and cause a short circuit, which is easy to cause damage to the pins of the secondary plug-in of the circuit breaker. The vibration can also easily cause the clip to fall; to open and close manually, you need to manually press the unlocking mechanical button, which is very dangerous

Moreover, the working efficiency of these two methods is very low, and the circuit breaker test takes a long time, which does not meet the high reliability requirements of the current power system.
