1、内蒙古科技大学高等职业技术学院毕业设计说明书(论文)摘 要本设计是继矿井开采与矿井设备选型设计之后,对采区供电进行的设计。本文通过利用矿井开采和设备选型设计成果,对变电所及配电点的位置的确定和供电系统中所需要的各种电气设备及电缆进行选择与校验,并对它们的保护装置进行了整定校验。最后再根据所选的设备、型号及采区条件,进行变电所硐室及设备的布置,确定硐室的大小,绘制变电所设备布置图以及供电系统图。本设计从实际出发进行系统分析,除满足一般设计规程,还满足《煤矿安全规程》的具体要求和标准。设计选用移动变电站一台、选变压器俩台。且向移动变电站供电的高压电缆选用
2、屏蔽监视型矿用橡套电缆,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暴真空开关和低压矿用隔爆真空馈电开关。其它设备开关均选为矿用隔爆真空自动馈电开关,再通过过电流保护装置整定计算,使设计可靠性高、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:采区供电变压器电缆开关IV内蒙古科技大学高等职业技术学院毕业设计说明书(论文)MiningareapowersupplydesignAbstractThisdesignisthecoalminingandmineequipmentselectionandde
