摘　　要：电力网电能损失率是电力企业的一项重要综合性技术经济指标,它反映了一个电力网的规划设计、生产技术和运行管理水平。在配电网安全性和可靠性日渐成熟后,降低线损变成配电网的一项重要工作,而大部分线路损耗是在10 kV以下的配电线路上。在配电线路上采用单、三相变压器混合供电方式,以高压进户、缩短低压线路、降低线损为目的,使配电线路线损有了较大幅度降低,提高了供电可靠率和电压合格率。Line loss rate is an important synthetic economical and technical index of electric power enterprise. It represents the level of the plan and design, production and technology as well as the operation and management of a electric power network. After the reliability and security of distribution network are ripe day by day, it becomes an important work to reduce the line loss for distribution network. The line loss of 10 kV and below distribution networks is the major part of total line loss. Taking shorten low voltage line with high voltage into users to reduce line loss as the purpose, the single-phase and three-phase transformer combined power supply way is adopted to reduce the line loss largely, improve the reliability of power supply and voltage eligibility rate.
