适用范围

This part of IEC 62271 specifies requirements for factory-assembled metal-enclosed switchgear and controlgear for alternating current of rated voltages above 1 kV and up to and including 52 kV for indoor and outdoor installation@ and for service frequencies up to and including 60 Hz. Enclosures may include fixed and removable components and may be filled with fluid (liquid or gas) to provide insulation.NOTE 1 Although primarily dedicated to three-phase systems@ this standard can also be applied to single-phase or two-phase systems.This standard defines several types of metal enclosed switchgear and controlgear which differ due to?C the consequences on network service continuity in case of maintenance on the switchgear and controlgear;?C the need and convenience of maintenance of the equipment. NOTE 2 Safety of an installation results from the design@ implementation and coordination of products@ installations and operations.For metal-enclosed switchgear and controlgear containing gas-filled compartments@ the design pressure is limited to a maximum of 300 kPa (relative pressure).NOTE 3 Gas-filled compartments having a design pressure exceeding 300 kPa (relative pressure) should be designed and tested in accordance with IEC 60517.Metal-enclosed switchgear and controlgear for special use@ for example@ in flammable atmospheres@ in mines or on board ships@ may be subject to additional requirements.Components contained in metal-enclosed switchgear and controlgear are to be designed and tested in accordance with their various relevant standards. This standard supplements the standards for the individual components regarding their installation in switchgear and controlgear assemblies.This standard does not preclude that other equipment may be included in the same enclosure. In such a case@ any possible influence of that equipment on the switchgear and controlgear is to be taken into account.NOTE 4 Switchgear and controlgear assemblies having an insulation enclosure are covered by IEC 60466.NOTE 5 Metal-enclosed switchgear and controlgear for rated voltages above 52 kV insulated by ambient air may be covered by this standard taking into account the insulation levels of IEC 60694.
