摘要
从实际出发进行系统分析,除满足一般设计规程及规范要求外,还满足《煤矿安全规程》的具体要求和标准。本设计变压器选用矿用隔爆型干式变压器和矿用隔爆型移动变电站;高压开关与低压馈电开关都选用具有技术先进的智能化综合保护装置的高压防爆真空开关和低压矿用隔爆型真空馈电开关,各种设备的开关选用矿用隔爆型真空起动器。高压铠装电缆选用交联聚乙烯绝缘聚乙烯护套电力电缆。通过短路电流、开关继电保护整定的计算和保护接地的确定,使其设计可靠性高、功能完善、组合灵活,以及功耗低,保证采区供电安全、经济、高效平稳运行。
关键词:负荷计算;设备选型;矿山电缆选择及效验
Abstract
From reality to undertake systems analysis, in addition to meet the general design procedures and requirements, but also meet the" coal mine safety regulations" requirements and standards. The design of transformer selection of mining flameproof dry type transformer and mining flameproof movable substation; high voltage switch and low voltage feeder switch are selected with advanced technology of prehensive protective device of high voltage explosion proof vacuum switch and low voltage flameproof vacuum feed switch, a variety of equipment switch selection of mining flameproof vacuum starter. High voltage 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 and stable operation.
Key words :Load calculation; Equipment selection; Mining cable selection and validation
