Changzhuang 35KV Power Transmission And Transformation Engineering Design

The main power supply area of 35 kV Changzhuang station is the surrounding areas of Xiachangzhuang Village.It is located in the edge intersection among Cuijiayu Town,Huangshan Town,and Yuandongtou Town.The regional area is 52.06km2.The pillar industrial is the exploitation and processing of mineral products,etc.The area has 2 lines from the 110 kV Cuijiayu Transformer Substation,2 lines of the 35 kV Huangshan Transformer Substation,1 10 kV line power supply from the 110 kV Yuandongtou Transformer Substation,including 24410 Lijiayu Line,2442 Changzhuang Line,445 Nannong Line,442 Zhenzhi Line,and 15 Yuandongtou 12 th Line which are located in the end of lines.Distribution transform capacity is 4280 kVA,3615kVA,9365 kVA,12500 kVA and 2075 kVA.All lines are old rural power grid lines with thin line diameter and long diameter of power supply.Network power supply load in the area in 2014 was 3.86 MW.The network power supply volume is 13.5 million kwh;10kV line has the long power supply diameter and it is not suitable for the demands of advancing regional economy rapidly.The capacity-load proportion in the 110 kV Cuijiayu Station is 2.1.It has the far distance from the area.Cuijiayu Town has no 35 kV transformer station or similar projects under construction.With the actual features of projects and combining with actual situation in Yishui power grid,the author explores a power transformer line with reasonable economy,simple operation,safety and reliability.After the project is implemented,it mainly satisfies the surrounding areas in Xiachangzhuang Village,Cuijiayu Town,Yishui Couty(the edge intersection among Cuijiayu Town,Huangshan Town and Yuandongtou Town).The load increase demands realize the synchronous power supply in the 10 kV line of Cuijiayu Station,Huangshan Town and Yuantoudong Station.
