变电站二次过电压防护技术

Secondary Overvoltage Protection Technique in Substation

变电站二次设备的过电压保护是以电子信息系统为保护核心,为被保护设备构建一个均压等电位系统,并通过各级过电压浪涌保护器逐级把电流泄放入大地,使变电站二次设备安全和可靠地运行。

Overvoltage protection of the secondary equipment in substation takes the electronic information system as the protection core. It constructs a voltage - sharing equipotential system for the protected equipment, and it releases the current to the earth gradually through all levels of overvoltage surge protector. Thus, it makes the secondary equipment of substation be in a safe and reliable operation.
