摘要
辅助开关受潮引起触点间绝缘击穿导致了本次开关误跳闸,在开关控制回路设计时应避免控制回路中带正电与带负电的位置相邻,最好隔出一定距离,并将开关就地保护动作信号应接入监控后台,以做到对开关动作信号全面监视。
Auxiliary switch he affected by damp caused insulation breakdown in contact lead to this switch tripping. The location with positive electricity and negative electricity were avoid adjacent in the control loop, had hatter have some distance, when switch control loop was designed. The actuating signal of protection switch was accessed to the background monitor, in order to overall monitor the switch actuating signal.
