Description
This document applies to pressurized partitions used in indoor and outdoor installations of high-voltage AC and DC switchgear and controlgear with rated voltages (Ur) above 1 kV AC / 1,5 kV DC and with design pressure higher than 300 kPa, where the gas is used principally for its dielectric and/or arc-quenching properties.
The partitions comprise pressurized barriers in electrical equipment not necessarily limited to the following examples:
- circuit-breakers;
- switch-disconnectors;
- disconnectors;
- earthing switches;
- current transformers;
- voltage transformers;
- surge arresters;
- busbars and connections;
- cable connections/terminations;
- cable bushings.
Partitions which are only pressurized from one side are also covered.
1 kV AC / 1,5 kV DC means it is valid for the apparatus applied and where the partitions are installed; however, the application of voltages below 1 kV AC / 1,5 kV DC as in, for example, current and voltage transformers are not excluded.
This document does not apply to high voltage bushings (see EN 60137, EN 61462 and EN 62155).
