敞开式变电所的占地面积,一般与电压等级的平方成正比的增加。在高压、超高压变电所中,如何缩小占地面积是一个重要的问题。为了弄清变电所占地面积与所用设备的型式和布置的关系,我们剖析了主结线为双母线带旁路的22万伏变电所的布置。现将软母线配用双柱(GW_4—220)隔离开关(见图1)及铝管母线配用单柱(GW_6—220)隔离开关(见图 The open area of ​​the substation generally increases in proportion to the square of the voltage level. In high-voltage, high voltage substation, how to reduce the footprint is an important issue. In order to understand the substation area and the type of equipment used and the layout of the relationship, we analyzed the main line for the double bus bypass 22 million-volt substation layout. The bus now equipped with double-pole bus (GW_4-220) isolating switch (see Figure 1) and aluminum bus bar with a single column (GW_6-220) isolating switch (see Figure
