FUR组合保护装置在江垭水电站厂用电系统中的应用

Application the FUR Assembled Protector to Electricity Consumption System of Jiangya Hydropower Station

通过在江垭水电站厂用电系统的改造中，采用FUR组合保护装置加普通真空断路器取代原有高压负荷开关，有效的防止了误动作，减少了操作过电压对主要电气设备的冲击，实现了动作的可选择性，降低了造价。该文对在选型过程中的步骤及应考虑的问题，给予了较深入的研究。

In the alteration of electricity consumption system of Jiangya hydropower station, the FUR protector was used instead of the ecumenical vacuum breaker, which results in preventing of error action by decreasing strike of high voltage to the major equipment, and realizing optimal action for lower down the investment. The approach and procedure for selection of the protector were expounded in detail in the paper.
