Abstract

Abstract:

Based on the rated DC operating voltage characteristics of communication DC circuit breakers, a short-circuit testing system for communication DC circuit breakers is designed using a large capacity multi magnetic circuit transformer. The system adopts the built-in rectifier circuit and the regulating impedance nearby, the independent control systems and mobile measurement systems to test a maximum short-circuit current capacity of 25 kA for rated voltage DC 100 V and below, which can be suitable for short-circuit testing of communication DC circuit breakers.

Key words: DC circuit breaker, ripple coefficient, mobile measurement system, short circuit
