农村小水电站二次保护回路整定,是电气设备安全运行的关键之一。目前小型水电站低压发电机电气控制大多数是用PKF盘为主控盘,本盘保护装置的目的只限于GL型反时限过流或速断,作用于DW空气开关,鉴于其保护装置少,且对保护整定没有正规调试,致使多数电站二次回路保护未能充分发挥,本人拟提出一个小水电站用自制水阻器对反时限过流继电器的简易调试方法,供大家参考。
The setting of the secondary protection circuit in rural small hydropower stations is one of the keys to the safe operation of electrical equipment. At present, most of the electrical control of low-voltage generators for small hydropower stations is dominated by the PKF disk. The purpose of this disk protection device is limited to the GL type inverse time overcurrent or snap-off, acting on the DW air switch. In view of its low protection device, Protection setting no formal debugging, resulting in most of the power station secondary circuit protection failed to give full play, I would like to propose a small hydropower station with self-made water resistance on the inverse time overcurrent relay simple debugging method for your reference.
