摘要:
The disclosure relates to an electrical switching device, e.g., a generator circuit breaker, and to a method for improved switching-gas cooling. Gas jets are formed by a nozzle body in the exhaust area, are directed against a baffle wall and are swirled. The baffle wall is a component of the switching chamber enclosure and has a high thermal capacity and/or thermal conductivity, so that the switching gas vortices produce a highly efficient switching gas cooling on the baffle wall by turbulent convection. Exemplary embodiments relate inter alia to the design of the baffle wall and of the nozzle body. Advantages include: protection of the switching chamber enclosure against hot gases, improved switching gas cooling, and increased breaking capacity.
摘要(中):
本公开涉及电气开关装置,例如发电机断路器,以及用于改进开关气体冷却的方法。 气体喷嘴由排气区域中的喷嘴体形成,被引导到挡板壁上并被旋转。 挡板是开关室外壳的一个部件,具有高的热容量和/或导热性,因此开关气体涡流通过湍流对流产生在挡板壁上的高效开关气体冷却。 示例性实施例尤其涉及挡板壁和喷嘴体的设计。 优点包括:保护开关室外壳免受热气体,改善开关气体冷却和提高分断能力。
