instantaneous overcurrent protection的意思|示意

Using the method of window moving in real time, the root mean square value of current of the last cycle was calculated as the criteria for instantaneous overcurrent protection.

用窗口实时移动的思想计算当前时刻以前一周波电流方均根值平方作为瞬动脱扣的判断依据。

The relay is made up of integrated circuits. The line instantaneous overcurrent protection and overcurrent protection are combined with the once 3-phase reclosure application to form a whole body.

该继电器采用集成电路构成，集线路的速断保护、过电流保护及三相一次重合闸于一体。

Protection of bus-tie circuit breakers: long time delay overcurrent and instantaneous overcurrent.

汇流排联络断路器保护：长延时过流、瞬时过流保护。

For backup protection against high resistive ground faults, there will be a dual polarized directional overcurrent relay, inverse time with instantaneous trip attachment.

对于后备保护装置防止高阻抗接地故障，将配置一只双极方向过电流继电器，同瞬时跳闸附件的时间成反比。
