摘　　要：冶金企业用电负荷普遍较大,供配电系统一般采用高电压、大容量主变压器,由此带来的问题是主变压器低侧短路电流很大,常规限制短路电流的措施存在各自短板,在企业供配电系统增容改造中也存在工程实施问题。零损耗深度限流装置有较宽的适用性,在限制供电系统短路电流的同时,降低电损耗,减少安装空间,实现配网安全、高能效运行,在类似项目中具有推广应用价值。The power load of metallurgical enterprises is generally large,and the power distribution system generally adopts high-voltage and large-capacity main transformer.And the short-circuit current at the low voltage busbar will be very high.The conventional measures to limit the short-circuit current have their own defect,and there are also engineering implementation problems in the renovation project.The zero loss depth current limited device has wide applicability.It can limit the short-circuit current,save energy,reduce the installation space,and realize the safe,high-energy and efficient operation of the distribution network.It has the value of popularization and application in similar projects.
