摘　　要：我国大多数低压配电系统使用三相四线制接线系统。由于单相负载不平衡等原因,容易导致配电变压器工作不平衡状态。分析了三相不平衡引起的配电变压器损耗和线路损耗的问题,并提出了低压配电网三相不平衡问题技术治理措施。Most low-voltage power distribution systems in my country use three-phase four-wire wiring systems.Due to unbalanced single-phase load and other reasons,it is easy to cause unbalanced operation of the distribution transformer.The problems of distribution transformer loss and line loss caused by three-phase unbalance are analyzed,and technical measures to solve the problem of low-voltage distribution network three-phase unbalance are proposed.
