摘　　要：介绍了电容器抑制发电机断路器开断后瞬态恢复电压上升率(RRRV)的原理以及采用电容器的必要性。通过仿真计算研究了不同电容值对TRV参数的影响。针对发电机断路器运行特性,介绍了防护电容器的特殊应用环境、设计标准、研制过程、以及可靠性和经济性的考量,并分别通过电容器和整机试验验证了其选取的合理性。This paper introduced the principle of capacitors suppression to rate of rise of TRV（RRRV）for the generator circuit breaker, and the necessity of capacitors. By simulating and calculating, the effects of different capacitor values on TRV parameters are studied. According to the operating characteristics of generator circuit breaker, the special application environment, design standards, development process as well as the considerations of reliability and economy are introduced. Moreover, the rationality of the selection for the capacitor is verified through the testing of the capacitors and the whole generator circuit breaker system.
