Reasearch on Arc Extinction Programs Simulation of DC High Speed Vacuum Circuit Breaker

对直流断路器研制的关键问题——直流高速真空断路器灭弧方案,介绍了几种典型的直流断路器灭弧方案的工作原理。在此基础上,结合具体实例,对采用电流转移原理,实现灭弧进行理论与Matlab仿真建模。仿真结果表明,采用电流转移原理灭弧的直流高速真空断路器具有可行性。

This paper performs an analysis on the essential question-Arc Extinction Programs of DC HSVCB,and work principles of several kinds DC circuit breaker are introduced. On the basis of this, combination with the concrete example, which adopts current commutation principle to make DC arc to extinct. Meanwhile,Theoretical analysis of arc extinction with its simulation models in Matlab are built in this paper. According to simulation, it is feasible that adopts current commutation principle to make arc to extinct of DC HSVCB.
