Abstract
Designed for six transport Lake Farm coal mining area power supply design. Proceeding from the actual systems analysis, General specification for design and specification except those that meet the requirements, also meet the specific requirements of the coal mine safety regulations and standards. Design selection of mine-used flameproof dry transformer of transformer and mine-used flameproof movable substation; selection of high-voltage switch with low voltage feed switch has the advanced technology of prehensive protective device of high voltage explosion-proof vacuum switch and low-voltage mining flameproof vacuum feed switch, various device switch selection of mine-used flameproof vacuum starter. Selection of HV armored cable xlpe insulated PE sheathed power cable. By short circuit current, switch of relay protection setting calculation and determination of the protective earth so that bination of perfect design, high reliability, functionality and flexible, and low power consumption, ensure the safety of mining area power supply, economical, efficient, smooth running.
