Spiral structure of sensor for detection of gas insulated switchgear

摘要

The present invention relates to a mounting structure of an external partial discharge detection sensor for detecting a partial discharge inside the gas insulated switchgear by detecting electromagnetic waves flowing out through the spacer installed in the gas insulated switchgear,;The fixing protrusions formed at the lower end of the external partial discharge detection sensor are installed to be in contact with the side surface of the spacer, and the lower end of the external partial discharge detection sensor is fixed to the spacer to measure the partial discharge. The fixing portion is characterized in that configured to be fixed to the outer peripheral side of the spacer.;In addition, the present invention can be used for a long time due to the simple configuration of the device to reduce the amount of trouble, can significantly reduce the maintenance and maintenance costs, and the external partial discharge detection sensor used by additionally configuring a conventional conductive strip or aluminum strip The production cost is reduced compared to the device.
