摘要
正确设计选择发电机保护断路器直接关系到水电站后期的电气设备合理投资、运行维护及保证水电站长周期安全经济地运行。过去中小型水轮发电机大都选用普通型的油断路器或真空断路器或SF6断路器等,近些年来选用普通真空断路器的越来越多。中小型水电站应根据不同接线方式、不同容量的发电机出口断路方法,选择发电机专用断路器。
Correct design of generator circuit breaker is directly related to thereasonable investment of electrical equipment,the operation maintenance,and the safe and economic operation of hydropower station.Medial-sized generators used to choose normal oil circuit breaker or vacuum circuit breaker or SF6 circuit breaker.In recent years,common vacuum breaker is becoming more and more popular.Small and medium-sized hydropower station should choose special generator circuit breaker according to different connection method and different capacity of generator circuit breaker method.
