The explosion proof switchgear is mainly used for starting and stopping three-phase asynchronous motors in coal mines through local control or intrinsic safety remote control, and can be reversed during shutdown.
Mining general low-voltage switchgear can be used as a complete set of low-voltage power distribution equipment in the 690V and 400V power supply system of substations in underground coal mines, underground yards without gas and coal dust explosion hazards, workshops with heavy dust corrosion, and wet places of metallurgy, subway and low buildings.
