quick-break怎么记

This paper mainly discusses the way to form current-voltage quick-break protection. The combinations of current quick-break protection, current bolcked-voltage quick-break protection and current-voltage interlocking quick-break protection can reach this goal when they work simultaneously.

论述了将电流速断、电流闭锁电压速断、电流电压联锁速断3种保护同时运行，组成电流电压速断组合的方法。

It can be used as an independent relay, including crossing current brake circuit, no braking quick-break circuit, preventing no-load starting transformer inrush current, and avoiding fifth harmonics of overexcitation running for high-power transformer.

它可以作单个继电器用，具有穿越电流制动回路，无制动速断回路，且可防止空投变压器励磁涌流的影响，对大容量变压器还可躲开过励磁运行时五次谐波的影响；

Mine existing quick-break power supply value can not be over-current protection setting, leakage protection and so difficult to achieve more difficult, leading to leakage, short circuit fault occurs frequently, a serious threat to reliability.

煤矿井下供电目前存在速断过流保护定值无法整定、漏电保护难实现比较等难题，导致漏电、短路等故障发生频繁，严重威胁供电可靠性。
