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;
Tyre crane using the diesel generator power, and diesel generator no-load running at high speed all the time waiting trucks 'operating intermittence, result in the unnecessary waste of diesel. 轮胎吊使用柴油发电机组供电,在等待集卡车的作业间歇时,柴油机组始终处于高速空载运转,从而造成了柴油的不必要的浪费。
