REX521GHHPSHO7G保护继电器 为保护 控制 测量和中压电网的监控
馈线保护测控装置的作用
馈线保护测控装置是电力系统中的一个重要保护设备,主要作用是在馈线发生短路、接地故障或其他异常情况时,快速切除故障,保护电力系统的稳定运行。它可以感应电力系统中的异常电流、电压信号,与事先设定的故障保护条件进行比较,当检测到故障时实现快速切断故障环节,防止故障向电网扩散。
馈线保护测控装置的原理
馈线保护测控装置的工作原理是基于安设在馈线上的电流、电压传感器,通过对故障信号的检测、测量、处理,进行故障的判断和快速切除。它采用数字信号处理技术,可以快速、准确地检测馈线故障,实现快速切除故障,保障电力系统的稳定运行。
The function of feeder protection measurement and control device
Feeder protection measurement and control device is an important protection equipment in the power system, its main function is to quickly remove the fault when the feeder occurs short circuit, ground fault or other abnormal conditions, to protect the stable operation of the power system. It can sense the abnormal current and voltage signal in the power system, and compare it with the preset fault protection conditions. When the fault is detected, it can quickly cut off the fault link and prevent the fault from spreading to the power grid.
Principle of feeder protection measurement and control device
The working principle of the feeder protection measurement and control device is based on the current and voltage sensors installed on the feeder line, through the fault signal detection, measurement, processing, fault judgment and rapid removal. It adopts digital signal processing technology, which can detect feeder fault quickly and accurately, realize fast fault removal, and ensure the stable operation of power system.
