摘要
介绍电力机车新型高压隔离开关的结构和工作原理,以及高压隔离开关的控制逻辑。对发生带载分断故障进行还原和原因分析,并提出相应的对策。优化后,高压隔离开关稳定运行半年以上,实践证明解决措施有效。
This paper introduces the structure and working principle of the new high voltage disconnector for electric locomotive, and the control logic. Restore and analyze the causes of on load breaking fault, and put forward corresponding countermeasures. After optimization, the high voltage disconnector has operated stably for more than half a year, and the practice has proved that the solutions are effective.
