摘　　要：大容量发电机出口是否要装断路器(GCB)在我国过去和现在都存在较大争议,如何正确应用,不同类型的机组有不同的要求。现在很多地方均在建设超临界或超超临界的大型燃煤火力发电机组,以便迅速扭转电力紧张局面。为取得较高的可靠性和经济性,都希望装设发电机出口断路器(GCB),从而使发电机出口断路器的供需矛盾扩大。文章介绍了我国大容量发电机出口断路器的应用状况及生产情况,同时对国外GCB制造技术的现状进行了介绍。指出了研发具有我国自主知识产权的大容量发电机出口断路器的必要性。The problem of application of generator circuit breaker （GCB） in China has different opinion with geater dispute, how to apply correctly, the generator trait of different type has different requirement. Now, superitical or super - supercritical firepower generator traits are constructed in many places, in order to reverse poster tense situation promptly. To get higher reliability and economy, it is hoped for adopting generator owlet circuit breaker, which makes the contradiction of supply and demand for GCB. The paper introduced the conditions of production and application of generator circuit breaker in China, and present situation of GCB production and technology abroad. It is pointed out the necessity of developing the generator outlet circuit breaker with the autonomous intellectual property of China.
