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

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.
