Mechanism Analysis of Low Voltage DC Circuit Breaker Based on Parallel Capacitor
摘要
Abstract
Some low voltage DC systems such as low-voltage DC distribution network and photovoltaic power generation system have increasingly high requirements for the breaking performance and economy of low voltage DC circuit breakers.The traditional lowvoltage DC circuit breaker characterized by long arc duration and slow breaking speed can not meet the demand,so it is necessary to develop a new type of low voltage DC circuit breaker.In view of the low voltage DC circuit breaker based on the shunt capacitance current transfer principle,the working principle are analyzed.The mathematical model of the current transfer process is established and the accuracy of the mathematical model is verified by experiments.The transfer current under different shunt capacitance values is explored.The method of improving the breaking ability of the DC circuit breaker by the action of the transverse magnetic field is proposed and verified by experiments.The researched low voltage DC circuit breaker has low cost,simple structure,fast breaking speed and high reliability,which can be an important reseach direction for new type low voltage DC circuit breaker.关键词
