Abstract
With the fast growth of the our country national economy£¬using the electricity also becomes important of the development and supervision in our country. Everywhere a series of electricity device are built.
This paper mainly introduces the design of 35kV substation of Woolen mill. It discusses the choice of main wiring, high pressure equipment and all kinds of the protection of relay, the calculation of load, short current and so on in detail, especially, the choice of main wiring, transformer and some electric equipment such as circuit breaker, current and Voltage sensor.
This design take the electric power supply and the transmission safe, reliable, is nimble, the economy as the principle. The design is closely related to reality in order to design the suitable substation by studying a lot of materials. Main transformer capacity choice is according to brings to shoulder how many, and considered Economic Operation, uses two transformers SL7£2500/35.
