Connection technology of joint surface of tungsten-copper alloy arc contact for GIS

摘要: 对GIS （气体绝缘全封闭组合电器）用钨铜合金弧触头接合面连接工艺进行研究，提出了适用于灭弧室用弧触头的连接工艺。分析了钨铜合金弧触头在机械寿命试验过程中电子束焊位置失效的原因，并对弧触头结构提出优化设计方案，为今后GIS设备的弧触头结构优化设计提供了一定的技术基础。

Abstract: By researching on the connection technology of joint surface of tungsten-copper alloy arc contact for GIS (Gas Insulated Switchgear), the connection technology suitable for arc contact for arc extinguishing chamber was put forward. The failure reasons of electron beam welding position of tungsten-copper alloy arc contact in the process of mechanical life test were analyzed, and the optimization design scheme of arc contact structure was put forward, which provided a certain technical basis for the optimization design of arc contact structure of GIS equipment in the future.
