Abstract: This paper is mainly designs the 110 kV transformer substation and it goes together with to give or get an electric shock the system.This thesis first according to the request that the design mission book put forward, drafted the design informations, and according to the design system give on data and circuits and all parameters of burden, analyze the development trend of burden, increase the necessity that the aspect clarifies to set up the station from the burden;Then pass to check a great deal of data, establish to design the method and the step of the 110 kV transformer substation.The main work of the thesis is divided into four aspects:
(1)The electricity is once part of designs.Chapter 1 goes to chapter 4s to pass the analysis to draw up to set up the transformer substation to generalize and a line direction to consider, and pass the rightness carry the data, safety, economic and dependable sex aspect consider, making sure the 110 kVs,35 kVs,10 kVs and stand the lord of use the electricity connects the line;Immediately after made sure the main transformer set through the burden calculation and the power supply scopes number, capacity and model number, also made sure that the station uses the capacity and the model number of the transformer;End, according to biggest keep on the calculating calculation result of the work electric current and short circuits, to the high pressure chopper, the insulation switch, female line, insulate the son and wear a tube, the electric voltage is with each other the feeling machine, the electric current is with each other the feeling machine to carried on to choose the type, thus completing the 110 kV electricity once part of design.
(2)Defend the thunder and connect ground of design.Chapter 5s made the characteristics that passes in and out the line to the transformer substation all levels burden, establishing to defend the thunder device differently.At the same time, at the request of operate, connect a ground of net to connect the place type, material and the protection measures in the all levels electric voltage also each have the dissimilarity.
(3)The high low pressure goes together with the electricity design.Chapter 6 according to go together with the basic request of the electricity device, at satisfied the economy burden of the different from the premise of the safety bottom, rightness three kinds ofly electric voltage grade to set to correspond of go together with the electricity device.
(4)The electricity is two times part of designs.Chapter 7s go to the analysis and understanding that chapter 10s pass to the typical model 110 kV transformer substation, making sure the electricity two times equipments arranges and installs to the all levels electric voltage indoorly, at the same time, in order to adjust the modern trend, carry out the transformer substation to automate completely, also did the detailed provision to the direct current power supply system that the automation request to install.Adjust one degree aspect in the electric power, use the microcomper to carry on the far-away place supervision, and establish the homologous microcomputer protection and equip to install automatically.
