摘要
DW10型断路器经过十几年的运行,随着用户负荷变化以及断路器自身设计缺陷,运行过程中出现了许多问题。对该型断路器存在的主要问题进行了深入分析,提出了增加短路短延时功能等解决方案,并通过在电网中运用,取得了很好效果。
After more than 10 years of operation, the DW10 circuit breaker begins to show many problems due to the users＇ load variation and its design defects. The main problems of the circuit breaker are analyzed, and solutions such as adding short time delay for short-circuit protection are proposed. The solutions are proved effective through practice.
