Mine electrical equipment
Conclusion At present, Chint products have no explosion-proof type, so they are not suitable for underground operation, places with gas and dust explosion risk and key places requiring mining equipment At present, the main products areļ¼ 1.Mining and dressing plant, generally not far from the mining area, is relatively safe and does not require explosion-proof. 2.Generally, the smelter is independent, and explosion-proof is not required. 3.Mining area, mine general step-down substation, ground substation, power distribution control, or other underground operation and living areas away from the core operation.

Mine total step-down substation
The mine total step-down substation refers to the power transformation and distribution facilities that introduce high-voltage electric energy from the power system and distribute power to the mine load after reducing the voltage.
The layout is divided into outdoor and indoor parts.
The outdoor part mainly includes 35-110kv incoming distribution device, main transformer, 6-10KV distribution line and lightning protection facilities.
The indoor part includes 6-10kV distribution room, control duty room, electrostatic capacitor room, auxiliary facilities and living room. 35-110kv distribution equipment can also be installed indoors in narrow site or areas with serious air pollution.
