PARTIAL DISCHARGE DETECTING DEVICE OF GAS INSULATED TRANSFORMER

摘要

A partial discharge detecting device of a gas insulated transformer is provided to offer a UHF sensor with high sensitivity by using an electromagnetic wave characteristic in each monitoring window and a wideband characteristic of a corn type sensor and a patch type sensor. A partial discharge detecting device of a gas insulated transformer includes a monitoring window(300) and a partial discharge detection unit(200). The monitoring window is formed on a predetermined part of an external surface of the gas insulation transformer and monitors an inner part of a gas insulation transformer(10). The partial discharge detection unit senses a partial discharge signal generated inside the gas insulation transformer. The partial discharge detection unit is installed on an inside surface of the monitoring window.
