Abstract：This design object is a railway traction substation 110/27.5 kV electrical a design. Railway traction substation in railway has a very important position, to provide the railway locomotive running traction energy. The design purpose to be their own major knowledge applied to real life. At the same time enhance their learning and self-study ability. For railway traction substation electrical once understand the basic design method.

This design is through self-study traction substation of relevant knowledge, and the use of the previous study specialized knowledge, finally completed certain railway traction substation 110/27.5 kV electrical a design. This design is in HuaJing teacher of meticulous guidance finish. It is the design of the main content:

According to the condition choose traction substation a wiring design part of wiring method, and draw a connection design;

According to the design conditions are short circuit calculation;

According to the design conditions for equipment selection and calibration, and lightning protection calculation;

Final design, and the working process of the analysis.

This design in addition to the traditional method to use the application of CAD drawing software to drawing. In the limited time completed certain railway traction substation 110/27.5 kV electrical a design, has obtained the satisfactory effect, achieve the expected design intent.

Through the design, learning to traction substation of knowledge, as well as the basic method of the equipment calibration.

Keywords: Traction substation; The factory power supply; High technology; The bridge connection.
