概述 Overview
西方发达国家及东南亚，南北美洲地区，大量使用单相变压器作为配电变压器。在供电分散的配电网络中，单相变压器作为配电变压器有较大的优点。它可
以减少低压配电线路的长度，减少线路损失，提高供电质量，采用了高效节能卷铁芯结构设计，该变压器的特点是采用柱上式悬挂安装方式，体积小，基建
投资小，减少低压供电半径，可降低低压线路损 60% 以上。变压器采用全密封结构，过负荷能力强，连续运行可靠性高，维护简单，使用寿命长。
适合农村电网，偏远地区，分散村落，农业生产，照明和动力用电，也可用于铁路，城市电网节能改造柱上式配电线路。
可单相运行或三台单相成组作为三相运行。
Western developed countries and Southeast Asia, North and South America, a large number of single-phase transformers are used
as distribution transformers. In a distributed distribution network, single-phase transformers have greater advantages as distribution
transformers. It can reduce the length of low-voltage distribution lines, reduce line losses, improve power quality, and adopts high-
efficiency energy-saving coil core structure design. The transformer is characterized by the use of on-column suspension installation,
small size, small capital investment, and reduced low pressure. The power supply radius can reduce the loss of the low-voltage line by
more than 60%. The transformer adopts a fully sealed structure, strong overload capacity, high continuous operation reliability, simple
maintenance and long service life.
Suitable for rural power grids, remote areas, scattered villages, agricultural production, lighting and power use, can also be used for
railway, urban power grid energy-saving retrofit column-type distribution lines.
It can be operated in single phase or in three single phase groups as three phases.
