Research on the Stability of Circuit Breaker Based on Sinusoidal Excitation

Abstract

With the rapid development of new technology of electrical, all walks of life to the reliability of low voltage circuit breaker and other electronic products requirements are increasingly demanding, low voltage circuit breaker as the main electrical equipment in the power distribution system to connect to the circuit and disconnect plays a decisive role in the railway road, maritime transport, strong shock and vibration. Natural mechanical environment has become one of the important factors affecting the safe operation of electrical equipment is stable and reliable. The circuit breaker is generally under static conditions to study the performance index, this paper circuit breaker on-off of dynamic reliability experiment, build platform, find the circuit breaker on-off phase Should the parameters (frequency, acceleration). This paper adopts Es-60Wls3-445/LT0606/LTT1212 electric vibration system stability test sine on SIEMENS 3VL2716-1AA33-0AA0 molded case circuit breaker, and to study its stability.
