inrush

The article takes water resisting floor as brittle rock mass, and thinks that water inrush from floor is caused by rock mass sliding along a fracture plane.

把隔水底板作为脆性岩体，认为底板突水是由于岩体沿断裂面发生滑动造成的。

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；
