标准简介

适用范围：

This standard applies to switches rated 72.5 kV and above intended for use in metal-enclosed, gas-insulated substations, including disconnecting, interrupter, and grounding switches. These switches are characterized by grounded, leak-tight metal enclosures that are filled with a gas (most commonly sulfur hex-fluoride, SF6) at some pressure above atmospheric, with live parts contained within the housing and insulated therefrom by the gas and by suitable solid insulation that supports the live… read more parts in their proper position. Gas-insulated switches are normally electrically connected to and structurally joined to other gas-insulated components such as buses, gas-to-air bushings, circuit breakers, instrument transformers, cable terminations, etc. Switches may be manually or power operated. read less
