摘要
本文对用MOV作变压器统组内保护的原理、接入方式、限压规律进行了理论和试验研究，并用相似理论对超高压大容量变压器进行降压真型试验，获得了宝贵数据，证实用MOV保护的优异效果。
In this paper an investigation has been made on the principle,connecting schemes and restraining voltage regularity for Metal Oxide Varistor (MOV) inner protection of transformer. And the reducing voltage experiments in the real EHV transformer by the similarity theory have been done. Sufficient data are obtained. It is proved that the method for inner protection of transformer is highly effective.
