110kV变电站中GIS双层出线方案研究

Research on GIS Double Outlet Schemes of 110 kV Substation

针对某110 kV变电站配电装置的出线规模,提出了不同于常规出线的双层出线方案。在双层出线与终端塔的配合形式中,提出了2种方案:方案一,采用2个双回路塔出线布置方案;方案二,采用1个四回路塔出线布置方案。研究结果表明:1)在出线方案满足带电距离的条件下,双层出线方案相比于常规出线方案极大地减少了占地面积,缩减了主母线长度;2)方案一和方案二针对于不同的出线走廊,各有优势,可依据实际情况选取。

According to the size of a 110 kV substation distribution equipment outlet, put forward a double outlet scheme different from conventional outlet. In the configuration of double outlet and terminal tower, presented two schemes. Scheme one applied two double loop tower outlet arrangement scheme; Scheme two applied a four loop tower outlet arrangement scheme. The research results show that： 1）Under the condition of meeting the charged distance in the outlet scheme, the double outlet scheme greatly reduces the floor space area comparing with conventional outlet, and reduces the length of the main bus; 2）For different outlet corridors of Scheme one and Scheme two, each has advantages and can be selected on the basis of actual situation.
