摘要
从一起施工现场的断电事故讨论了变压器是否需要更换、变压器低压侧是否需更换更大的主开关、负荷对保护开关的要求等几个问题。并总结、提出了配电设备选用时应注意的一些事项,以供设计人员参考。
Several problems that the necessity of changing transformer and bigger main switch in low voltage side of transformer, load＇ s requirements to protection switch were discussed from a power-off accident in construction site. Several items that should be paid attention to when selecting the distribution equipment were summarized and put forward. It could provide references for designers.
