Research on Self-Triggered Hybrid DC Circuit Breaker with Coupled Inductors
摘要
Abstract
To improve the interruption performance of DC circuit breakers in photovoltaic systems,a self-triggered hybrid DC circuit breaker(HDCCB)based on coupled inductors is proposed,which uses a miniature circuit breaker as the mechanical switch.Based on the experimentally measured arc volt-ampere characteristics,an interruption model of the proposed HDCCB is established.The coupled inductors reduce the rise rate of the fault current,thereby limiting its peak value.In addition,advancing the turn-on instant of the IGBTs shortens the overall interruption time of the circuit breaker.At high voltage levels,the voltage division and current limiting capabilities of the inductors contribute to high-capacity interruption.The results show that the proposed breaker interrupts a 15 kA current in 4.45 ms at a 1 500 V voltage level.关键词
