Abstract
This article according to the system logical circuit which and the load parameter in the project description gives, the analysis plans to construct the transformer substation to enter material and so on going beyond a line direction and load, from aspects and so on reliability, security, efficiency considered, has determined the electrical main wiring way. And through to shoulders the material the analysis, safe, the economy and the reliable aspect considered, had determined 110kV,35kV,10kV as well as the station use electricity the main wiring, then calculated through the load and supplies power the scope to determine the main transformer Taiwan number, the capacity and the model, simultaneously also had determined stood with transformer's capacity and the model, finally, according to most greatly continually the operating current and the short circuit computation's computed result, to the high-pressured fuse, the isolator, the bus bar, the insulator and put on the wall drive pipe, the voltage transformer, the current transformer has carried on the shaping, then carried on the power distribution equipment and the plane layout design as well as the anti-radar design, thus has completed 110kV electricity partial designs.
