三线集束导线两火-零低压供电新模式的实施与展望

针对我国农村地区供电负荷分散、用电量小的特点，研究以低压侧中间带抽头的单相配电变压器，配合两火一零三芯集束导线低压供电的新模式，并在赤峰市敖汉旗进行了试点。实施表明．该模式在工程投资、降损节能、安全运行等方面已收到显著的效果，为今后农村电网特别是西部地区电网的建设与改造提出了一个新的思路。

Implementation and Prospects of Power Supply Mode Based on New Type of Split Insulated Conductors Consisted of Two Lines and One Neutral

When the second phase reconstruction of rural electric power network carried out, a new low-voltage power supply mode was adopted, that the secondary winding of a single-phase distrihution transformer connected to the loads by bundle insulation conductors consisted of two lines and one neutral and separated from each other by insulating rnaterials. It was tentatively applied to three villages in Aohan county of Chifen city. The result show this pattern operates effective on many aspects such as reducing the investment to project, diminishing line loss and economizing electric power energy, and safely running. This new pattern developed a new idea for future construction and reconstruction of rural electric power network.
