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 intelligent comprehensive 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 its combination of perfect design, high reliability, functionality and flexible, and low power consumption, ensure the safety of mining area power supply, economical, efficient, smooth running. keyword: power supply design; use of a transformer; switch; cable 目 录 TOC \o 1-3 \h \z \u   HYPERLINK \l _Toc296167163 摘 要  PAGEREF _Toc296167163 \h I  HYPERLINK \l _Toc296167164 Abstract  PAGEREF _Toc296167164 \h II  HYPERLINK \l _Toc296167165 第1章 工作面概况  PAGEREF _Toc296167165 \h 1  HYPERLINK \l _Toc296167166 1.1 工作面位置及井上下关系  PAGEREF _Toc296167166 \h 1  HYPERLINK \l _Toc296167167 1.2 煤层  PAGEREF _Toc296167167 \h 1  HYPERLINK \l _Toc296167168 1.3工作面工业储量计算  PAGEREF _Toc296167168 \h 2
