GB/T 22580-2008Specific environmental condition - Technical requirements of electric equipments used for plateau - Low-voltage switchgear and controlgear assemblies (English PDF)

1 Scope

This standard specifies the altitude above 2000m to 5000m within the range plateau Low-voltage switchgear and control equipment (hereinafter

Called "plateau equipment") terms and definitions, plateau environment condition parameters, requirements, test specifications, materials, packaging, transportation and storage requirements.

This standard applies to an altitude of more than 2000m to 5000m, rated AC voltage does not exceed 1000V, frequency does not exceed

1000Hz, DC rated voltage not exceeding 1500V plateau of equipment.

This standard applies to electricity generation, transmission, distribution and power conversion equipment and control power consumption of complete sets of equipment for use equipment.

The standard equipment also applies to the control and is equipped with a frequency higher power devices, such as electronic devices into power distribution equipment sets

Equipment with soft-start function of complete sets of equipment. In this case, additional requirements should be used.

This standard also applies to those special conditions of use for the equipment and design, such as ships, locomotives, machine tools, lifting equipment use

Complete sets of equipment, or equipment for use in potentially explosive atmospheres and civilian equipment that is used by non-professionals, as long as they meet the relevant

Requirements.

This standard does not apply to individual components and self-contained components, such as motor starters, fuse switches, electronic equipment, provided above

Preparation should conform to their respective standards.
