Circuit breaker simulator DY-ML

1、 Product introduction

DY-ML analog circuit breaker is mainly used for the whole group test of power system outage protection device or complete set of relay protection screen, which can truly simulate the tripping and closing time of the circuit breaker. During the whole group test, simulate the tripping and closing of high-voltage circuit breakers to avoid adverse effects caused by repeated opening and closing of circuit breakers due to repeated whole group tests.

The circuit breaker adopts full digital circuit, and the time is set by digital dial code. It can realize functions such as setting of tripping and closing time of analog circuit breaker, selection of three-phase/split phase operation, logic control of input signal, etc., so as to simulate tripping and closing actions of the circuit breaker.
