分接开关级间过电压的保护装置

Tab Changer Tapping Step Overvoltage Protective Device

介绍了分接开关级间过电压、级间过电压产生机理及火花间隙。介绍了用火花间隙、ZnO压敏电阻器保护装置以限制过电压的工作原理以及采取这些保护措施后的特性、两种不同的保护措施各自适用的工作场合。

Introduced the tap changer tapping step overvoltage, the tapping step overvoltage produce the mechanism and the arcing distance. Introduced after the arcing distance, the ZnO varistor protective device uses to limit the overvoltage the principle of work as well as takes these protective measures the characteristic, two kind of different protective measures respectively suitable work situation.
