变配电所设计中普遍存在的问题综述（Survey of problems existing in the design of Substation）

变配电所设计中普遍存在的问题综述（Survey of problems existing in the design of Substation） 10, 6 kV substation and 6/0.4kV substation design, 10, construction projects are very common and very important work, its norms and technology are very strong, many aspects related to the implementation of the national mandatory provisions. To do the design of substation, we must carry out the current regulations and procedures of the state, and meet the specific requirements of the local power supply departments, otherwise there will be a variety of problems, affecting the quality of the design and progress of the project. In order to make the design of variable distribution, now I have been checking the hydropower engineering drawing and substation design drawings and found a part in a variety of problems sorted out, analyzed briefly, communicate with everyone, so as to improve. 1. the name of the substation and the power distribution station should be designed accurately and not at will. In the design documents of specific projects, it is not appropriate to use the name power distribution station in general. Transformer substation is the general term of transformer substation and distribution station. It is only used in general. When it comes to a particular category or an individual, they should be referred to as substations or distribution stations. In the GB50053 94 10kV and below substations design specifications, substation is the explanation of 10kV and the AC power supply through the power transformer to supply electricity to electric equipment; explanation is the only distribution open and closed high voltage distribution power distribution effect device bus without transformer. In the substation and power distribution equipment are sometimes to lift the pressure as the main function, including a high voltage distribution device, known as the substation to distribution as the main functions include a 3 ~ 10/0.4kV transformer, called distribution. A project has a plurality of substat
