(完整word版)110kV变电所毕业设计
摘要
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。
关键词：

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。
Key phrase:
Change to give or get an electric shock
Main transformer Current calculation
Short circuit calculation
