在现场施工 ,若停电将严重影响施工顺利进行 ,因此有些工地自备了柴油发电机组或采用双回路电源作为备用电源。但是 ,常常因工人误操作造成事故 ,文章根据施工现场的实际情况改造了现场双回路电源切换电路 ,可自动地由备用电源转到主电源向用电设备供电 ,又确保主电源有电时备用电源不会投入
In the construction site, if the power outage will seriously affect the smooth progress of the construction, some construction sites have their own diesel generators or dual-loop power supply as backup power supply. However, accidents are often caused by workers’ misoperation. According to the actual situation at the construction site, the article rebuilds the on-site double-circuit power switching circuit. It automatically switches from the standby power source to the primary power source to supply power to the electrical equipment, Power will not be put
