提出一种井下高压隔爆开关欠电压保护改造的新型方案。对井下高压隔爆开关中的欠电压保护装置设置2～3s的延时,并设置在井下大量的高压线路开关上,当出现各类停电故障并需短时恢复时,能显著减少全面恢复供电的时间。
Proposed a new type of underground high voltage flameproof switch undervoltage protection transformation of the new program. Set up the delay of 2 ~ 3s to the under-voltage protection device in the underground high-pressure flameproof switch and set a large number of high-voltage line switches in the well. When all kinds of blackouts occur and need short-term recovery, it can significantly reduce the power supply time.
