摘要

GIS防爆膜是防止GIS设备因内部气压骤增导致壳体爆炸的重要泄压设备，其位置的选取和参数的设计与GIS内部燃弧故障紧密相关，文中针对一起220 kV GIS防爆膜的误动作故障，基于GIS内部故障电弧引起壳体内部压力增加的原理，分析不同电压等级下GIS防爆膜的气室选择依据和设计参数选择，论述了该GIS设备防爆膜设计存在的严重错误，该分析结论对GIS设备防爆膜的选型和验收具有重要的参考意义。

Abstract

Rupture disc for GIS is an important pressure relief device to prevent GIS equipment from explosion due to sudden increase of gas pressure inside GIS equipment. The selection of its position and design of parameters are closely related to internal arcing fault of GIS. In view of mal-operation of rupture disc of 220 kV GIS

the selection basis of gas compartment and design parameters selection of rupture disc of GIS at different voltage levels are analyzed on the basis of principle of internal pressure increase inside the enclosure due to fault arc inside GIS. The serious mistake in the design of rupture disc of GIS equipment is described. The conclusion of the analysis is of great significance for the type selection and acceptance of rupture disc for GIS equipment.
