Full Description

Scope

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 hexa-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 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.

Abstract

New IEEE Standard - Inactive-Withdrawn.Withdrawn Standard. Withdrawn Date: Jan 10, 2002. This IEEE Standards product is part of the C37 family on Switchgear, Substations and Protective Relays. Requirements for switches rated 72.5 kV and above, intended for use in metal-enclosed, gas-insulated substations, are presented. These switches are characterized by grounded, leak-tight metal enclosures that are filled with a gas (most commonly sulfur hexafluoride, SF6) at some pressure above atmospheric. Live parts are contained within the housing and insulated therefrom by the gas and by suitable solid insulation that supports the live 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. Service conditions, ratings, supporting structures, and nameplates are covered. Testing of disconnecting and grounding switches is covered.
