井下电网电压等级 | 2011-8-6 10:28:00

井下电网电压等级

1．电网等级
    煤矿井下电网与地面三相四线制电网不同，其电压等级有特殊的规定，《煤矿安全规程》规定，煤矿井下各级配电网络电压和各种电气设备的额定电压等级，应符合下列要求：
      （1)高压，不超过10 000 V；
      （2）低压，不超过1140V；
      （3)照明、信号、电话和手持式电气设备的供电电压，不超过127 V；
      （4）远距离控制线路的额定电压，不超过36 V；
      （5)采区电气设备使用3300V供电时，必须制定专门的安全措施。
    2.煤矿井下供电系统的基本要求
      （1)煤矿井下属于一类用户，停电会造成人员伤亡和重大的生产损失；
      （2）煤矿井下供（配）电网不允许采用中性点接地工作方式，不允许井下配电变压器中性点直接接地，严禁由地面中性点直接接地的变压器或发电机直接向井下供电；
      （3)矿井电网短路容量，老矿井一般限制为50 mVA；新建矿井不再作此限制（一般为100 mVA或200 mVA）；
      （4）矿井高压电网，必须采取措施限制单相接地电容电流，使之不超过20 A。
