220kV变电站电气一次部分设计技术探析

随着国民经济的快速发展,人们对电力的需求越来越多,变电站在电力传输系统中具有非常重要的作用,因为它在整个传输系统中起到变换电压,并进行再次分配及控制的作用,保障人们生活用电的需求。由于变电站在电力传输网的重要作用,它的功能对电网的可靠性有着决定性的影响,直接关乎着整个电网运行的稳定。根据变电站设计的不同,可将变电站分为一次和二次之分,一次设计中主要是主接线设计、电气设备的选择、接地以及防雷等设计。

With the rapid development of national economy, people need more and more power. Substation plays a very importantrole in the power transmission system, because it plays the role of switching voltage in the entire transmission system. And redistribu-tion and control of the role, to ensure the demand for electricity for people＇s lives. As substation plays an important role in powertransmission network, its function has a decisive impact on the reliability of the grid, directly related to the stability of the entire gridoperation. According to the different substation design, the substation can be divided into primary and secondary, the primary designis mainly the main wiring design, electrical equipment selection, grounding and lightning protection design.
