High-voltage switchgear and controlgear — Gas-filled cast aluminium alloy enclosures (Adopted CENELEC EN 50052:2016, 2016-10, with Canadian deviations)
Scope

This European Standard applies to cast aluminium alloy enclosures pressurized with dry air, inert gases, for example sulphur hexafluoride or nitrogen or a mixture of such gases, used in indoor or outdoor installations of high-voltage switchgear and controlgear above 1 kV, 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 and with gas-filled enclosures with design pressure higher than 300 kPa relative pressure (gauge);
  • and with rated voltage above 52 kV. 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
