直流高速真空断路器灭弧方案的仿真研究

摘要

With the fast development of HVDC transmission , the manufacturing ability of DC circuit breaker becomes an impor-tant factor that restricts its progress .Aiming at the essential question -arc extinction program of DC high -speed vacuum cir-cuit breaker (HSVCB), the working principles of several typical arc extinction programs for DC circuit breaker are intro -duced.On this basis, combining with the example, the theory of adopting current transfer principle to extinct DC arc are ana-lyzed and its simulation models in Matlab are established .The simulation results show that it is feasible to adopt current trans-fer principle to extinct the arc for DC HSVCB .%　　随着直流输电技术的快速发展，直流断路器的研制水平成为制约其发展的一个重要因素。针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。
