Abstract
The power supply design from reality, has carried on the system analysis, in addition to meet the general design procedures and requirements, but also to meet <safety regulations in coal mines>, specific requirements and standards. The design of transformer selection flameproof dry-type transformer and mining flameproof movable substation; high voltage switch and low voltage feed switch selection of the advanced technology of prehensive protective device of high voltage explosion proof vacuum distribution device, and the low voltage flameproof vacuum feed switch; switch that controls a load selection of mining flameproof vacuum starter; high pressure armored cable with XLPE insulated PE sheathed power cable. The short circuit current, switch and relay protection setting calculation and protection of grounding is determined, the design of high reliability, perfect function, bination and low power consumption, ensure the power supply security, economic, efficient, stable operation.
