High-voltage breaker energy-storing motor time testing apparatus

Abstract

Provided is a high-voltage breaker energy-storing motor time testing apparatus which comprises an energy-storing motor power control switch for controlling the energy storage of the high-voltage breaker energy-storing motor. The energy-storing motor power control switch is connected with an energy-storing signal output port which is connected with a high-voltage breaker aviation plug via a secondary adapter. A current transformer connected between the energy-storing motor power control switch and the energy-storing signal output port is connected with a CPU module used for achieving calculation of energy-storing time of the energy-storing motor, outputting calculated results, and driving a liquid crystal display screen. A signal processing and analog-to-digital converting module is connected between the current transformer and the CPU module and capable of performing signal processing and analog-to-digital conversion on a converted signal of motor energy-storing power current flowing through the current transformer. The CPU module is connected with a liquid crystal display screen used for displaying testing results such as breaker energy-storing time or the like and formed by a color liquid crystal display module. The high-voltage breaker energy-storing motor time testing apparatus has characteristics of simple structure, easy manipulation, and good universality.

Description

technical field [0001] The invention relates to a time testing device for an energy storage motor of a high-voltage circuit breaker, which belongs to the technical field of electric equipment tools. Background technique [0002] The test of high-voltage circuit breaker energy storage motor is an important item in the maintenance test of 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 energy storage 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 testing process, since the circuit breaker characteristic instrument does not provide energy storage power, it needs to be clamped to the co...

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 pointer of the secondary plug-in of the circuit breaker. Vibration can also easily cause the clip to fall; and the efficiency of this working method is also very low, and the circuit breaker test takes a long time, which does not meet the high reliability requirements of the current power system
