Mining Low-Voltage Power Distribution Cabinet
Scope
This standard specifies the model, basic parameters, technical requirements, test methods, inspection rules, marking, packaging, transportation and storage of GKD series general-type low-voltage switchgear for mining (hereinafter referred to as switchgear).
This switchgear is applicable to power supply systems in central control rooms, underground parking lots, electromechanical chambers of main ventilation tunnels of non-coal mines and other similar mines. It serves as power receiving, feed-out, control, protection and power conversion equipment for power distribution, lighting, motors and other electrical equipment in 1140 (660, 380) V systems. The switchgear is also applicable to ground substations and power supply systems in metallurgy, chemical industry, electric power and other sectors.
