摘要
电动机配电断路器短延时和瞬时过电流脱扣器整定均与电动机起动特性密切相关.本文根据电动机不同起动方式进行整定探讨,并给出相应短路整定速查表.
The setting of short delay and instantaneous overcurrent tripping device of motor distribution circuit breaker are closely related to the starting characteristics of the motor.This paper discusses different starting modes of the motor and gives the corresponding short circuit setting speed check table.
