摘要
由上海电器科学研究所(集团)有限公司组织有关企业共同开发了新型的DW50 1000万能式断路器。介绍了该断路器的特点、性能指标以及主要技术参数。断路器具有一种新颖的手动操作机构,能确保DW50断路器在主触头闭合时不会再储能,而在主触头断开时能正常储能。
A new type DW50-1000 air circuit breaker developed by Shanghai Electrical Apparatus Research Institute Group Co., Ltd which organized some enterprises was introduced. The features, performances and main technical parameters of DW50-1000 were introduced in this paper, especially a new manual operation mechanism of the circuit breaker. The manual operation mechanism ensures that the circuit breaker can not store energy when the main contacts have closed, and can store energy as normal with the main contacts open.
