为满足经济发展的需要，根据有关单位的决定修建1座110KV盐北变电所。
本工程初步设计内容包含变电所电气设计，新建的盐北变电所从110KV侧东郊变电所受电，其负荷分为35KV和10KV两个电压等级。
通过技术和经济比较，现采用下列方案：
1. 内设两台三绕组变压器，电压等级为121/37.8/11。
2. 110KV进线采用内桥接线形式。
3. 本工程初步设计内容包括变电所电气设计。
4. 35KV和10KV配电装置同样采用单母线分段接线。
5. 所用电分别从10KV两端母线获得。
-For satisfying the demand that economy development, the authorities concerned decide to construct a YanBei transformer substation.
This engineering first step design contents includes the transformer substation of electric Design. The new-et up salt a YanBei transformer substation obtain power form Dong Jiao substation (110KV) . There are two kinds of local loads in the substation,. One is 35KV,the other is 10KV.
Pass the technique to compare with the economy, adopt the following scheme now:
1. There are two three-winding transformers in the substation. Voltage grade adopt 121KV 38.5KV and 11KV.
2. For 110KV main electrical connections shall adopt inside bridge connection.
3. The 110KVenters the line 2 return, The adoption builds trolley wire.
4. For 35KV and 10KV main electrical connections employ single sectionalized bus.
5. Auxiliary power system get power form the 10KV sectionalized bus.
