Feasibility Study And Engineering Scheme Design Of Power Supply Transformation Project Of "Sangongyiye" Separation And Transfer In Staff Family Area

The separation and transfer of water,electricity,winter heating and property management(collectively referred to as "three supplies and one industry")in the residential quarters of the family members of the employees of the state-owned enterprises is an important measure to separate the social functions of the state-owned enterprises that do not belong to them,it is convenient for enterprises to concentrate resources,improve their international competitiveness,develop their main business and reduce their burden of production and operation.At the same time,it can also further improve the living environment of employees.According to the actual demand on the spot,the reliability of the power supply and the safe operation period of the equipment,the transformation of the district is carried out according to the operation and maintenance standard of Datong company.The reconstruction includes 110 kv interval primary and secondary equipment,switch station,Ring Net box,box transformer,low voltage cable branch box,power metering box,high and low voltage cable,etc..The project design scheme adopts the typical design of State Grid Company as far as possible except that the site construction condition is not available.The load of related equipment and material selection is backcalculated according to the standard of 2.5 kw per household,and a certain simultaneous coefficient is considered.At the same time,considering the universality of equipment and material in the later stage of construction,the type and variety of material are compressed under the condition of satisfying the actual demand on the spot,and reference to the standard material selection requirements of State Grid Corporation.The principle of the separation and transfer of the Datong municipal government,there are two modes: "transformation first,then transfer" and "transformation first,then transfer",the feasibility and feasibility of the project are demonstrated for the reconstruction of the power supply facilities of 10 kv and below in the 4 Worker’s family areas,such as the Datong Coal Mining Group.It adopts the mode of "handing over first and reforming later".As the transferring party(the same coal enterprise)is not clear about the load of the high and low voltage power supply paths and equipment in the workers’ family area,in order to ensure the safe and reliable operation in the later stage,the design and construction plan of this project mainly take the new construction as the main part,and the reconstruction as the auxiliary,the equipment and materials used are typical national network design,standard materials.
