Abstract:This graduation project for Zhejiang science and technology institute 2003 level of electrical engineerings and automation specialized (undergraduate course) graduation project, designs the topic is: 35KV transformer substation expansion design.This design duty is for the purpose of manifesting to this specialty various branches knowledge grasping degree, raises carries on the synthesis utilization to this specialty various branches knowledge ability, since simultaneously has examined this specialty to study four year the study results.
First acts according to in the project description to give the system logical circuit and all load parameter, the analysis load trend of development.Had expounded from the load growth aspect the station construction necessity, then through to plans to construct the transformer substation the summary as well as the going beyond a line direction considered, and through to shoulders the material the analysis, safe, the economy and the reliable aspect considered, had determined the 35kV transformer substation uses 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 the transformer capacity and the model, finally, according to the most greatly continually operating current and the short circuit computation computed result, to the high-pressured circuit breaker, the isolator, the generatrix, the insulator and put on the wall drive pipe, the voltage transformer, the current transformer has carried on the shaping, thus completed35kV transformer substation electricity design.
