Abstract
With the development of DC power technology,DC circuit-breakers play a key role in the high and low voltage DC power system,the test technology and test circuit have become the hot topic in the high power laboratory.This paper discusses the DC current interruption technology and test circuit of medium-low and high voltage DC circuit-breaker respectively.The test capability of medium-low voltage DC circuit-breaker is proved to be 2 kV/82.6 kA with peak value of 126.2 kA,which can meet the test requirements of 1.8 kV/80 kA DC circuit-breakers.Additionally,the direct and synthetic test circuits of high voltage DC circuit-breakerare provided,and the typical test results of direct test circuit are given.The research of this paper helps low voltage and high voltage DC circuit-breaker current interruption test circuit designin high power laboratory.关键词
