过电压保护器的特点及应用 过电压保护器具有动作快、伏安特性平坦、残压低、性能稳定、组装维护方便等优点。对于相间和相地过电压都能起到有效的保护作用。过电压保护器主要用于保护发电机、变压器、开关、母线、电动机等电气设备的绝缘免受过电压的损害。

The characteristics and applications of over voltage protector are fast action, good volt ampere characteristic, low residual voltage, stable performance, convenient assembly and maintenance, etc. It can play an effective protective effect on both phase and phase overvoltage. The overvoltage protector is mainly used to protect the insulation of electrical equipment such as generators, transformers, switches, busbars, motors and other electrical equipment from overvoltage damage.
