电力变压器继电保护问题探析

变压器是电力系统中较为重要的电气原件,它具有故障小,结构可靠的特点,但是在实际的运行过程中,还是会产生一定的故障和异常情况。因此,为了减少故障对电力系统造成的影响,保护电力系统的安全运行,必须根据电力变电站的容量、电压的等级情况,安装可靠性较高的继电保护装置。随着电力电子技术的不断发展,微机已在电力变压器的继电保护中起到至关重要的作用,就此对电力变压器微机继电保护进行简要的分析。

The Explore on Power Transformer Relay Protection Problems

The transformer is an important power system electric original,it has the characteristics of little faults,reliable structure,but in the actual running process,there will be some failures and anomalies. Therefore,in order to reduce the failure impact on the power system and protect the safe operation of power system,we must install higher reliability of protection devices based on the capacity of the power substation,the voltage level of the situation. With the continuous development of power electronics technology,microcomputer has played a vital role in computer relay protection of power transformers. Now the power transformer protective relay is analyzed briefly.
