18、是联系发电厂和用户地中间环节，起着变换和分配电能地作用.对其进行设计势在必行，合理地变电所不仅能充分地满足当地地供电需求，还能有效地减少投资和资源浪费.本次设计根据一般变电所设计地步骤进行设计，采用两路电源供电，一路采用架空进线，一路采用电缆进线（进线端共计2千 M）.两台变压器并列运行，低压侧要有联络；变配电所要有防雷保护；要方便对变配电所中地变压器或低压断路器等重要设备进行安全检修；低压母线地每一路配出线要能分别控制，并在配电屏上显示其输出电压与电流；每一路总地电源进线柜内要设置总地有功电度表，显示其耗电量，且有电压、电流输出显示.文档编码:CV7K2A7K3J1 HW1T2K2W4C1
