Tracked Changes (Redline) - High-Voltage Switchgear and Controlgear – Gas-filled wrought steel enclosures

active, Most Current
Organization: BSI
Publication Date: 27 February 2020
Status: active
Page Count: 119
ICS Code (High voltage switchgear and controlgear): 29.130.10
scope:

This document applies to wrought steel enclosures and their welding. These enclosures are pressurized with dry air, inert gases, for example sulphur hexafluoride or nitrogen or a mixture of such gases, used in indoor and outdoor installations of high-voltage switchgear and controlgear with rated voltages above 1kV, where the gas is used principally for its dielectric and/or arc-quenching properties with rated voltages:

- above 1 kV and up to and including 52 kV concerning gas-filled compartments with design pressure higher than 300 kPa relative pressure (gauge);

- above 52 kV concerning all gas-filled compartments.

The enclosures comprise parts of electrical equipment not necessarily limited to the following examples:

- circuit-breakers;

- switch-disconnectors;

- disconnectors;

- earthing switches;

- current transformers;

- voltage transformers;

- surge arrestors;

- busbars and connections;

- etc.

The scope also covers enclosures of pressurized components such as the centre chamber of live tank switchgear, gas-insulated current transformers, etc.
