Abstract According to the load nature of the workshop , the subsection situations of the size of load and load, solve the distribution problem safe , reliable , economic to the workshop . On the basis of analysing two kinds of application that mainly wire , have put forward the scheme of adopting a voltage transformer of low-voltage tie line, have solved the problem that this shop loading is little but load dependability is expected much; And according to modern industry, hoist tonnage increase day by day , run distance to be longer and longer even, how is it touch voltage on the line is it exceed problem of allowing etc. to lower , take to solve the problem properly in the course of designing to slip to deal with, touch the line, the insulator pillar of realizing slipperily the low-voltage losses , high strength after adopting a kind of new-type low impedance rigid body, have improved the reliable performance of the distribution。
