Abstract

The paper focuses on the current commutation between the vacuum arc and the IGBTs of DC micro-grid hybrid circuit breakers (HCB). The principle of the DC HCB is analyzed and the current commutation is the important process in DC HCB interruption, on which the arcing time and the interrupting time are depended. The test circuit of the current commutation is established by simplifying the parallel-connected IGBTs to an on-state resistance with large thermal capacity. The influence of the magnitude of the main current, the resistance of the IGBTs and the externally applied transverse magnetic field (TMF) on the current commutation is investigated by the electrical measure and the development of vacuum arc which is observed by a high speed CMOS camera. The mathematic description of the current commutation is obtained. The interaction between the vacuum arc commutation and the externally applied TMF is discussed. The paper provides the bases on the optimal design and control strategy of DC HCB.

直流微电网混合断路器的电流换相特性

研究了直流微电网混合断路器中真空电弧与igbt之间的电流换相问题。分析了直流高压断路器的工作原理，指出电流换流是直流高压断路器断流的重要过程，它决定了直流高压断路器的起弧时间和断流时间。通过将并联igbt简化为具有大热容的导通电阻，建立了电流换流的测试电路。通过电学测量和高速CMOS相机观察到的真空弧的形成，研究了主电流大小、igbt电阻和外加横向磁场对电流换流的影响。给出了电流换相的数学描述。讨论了真空电弧换向与外加TMF的相互作用。本文为直流高压断路器的优化设计和控制策略提供了依据。
