摘要
焦作电厂厂用电源直接从发电机出口引接，经厂用高压变压器向厂用高压母线供电。为限制短路电流水平，厂用高压变压器采用低压为分裂绕组的分裂变压器；厂用高压母线采用单母分段接线，其中两互为备用的母线之间无连接。六台机组共设置三台启动/备用变压器，#1高备变接于焦电110KV母线，#2、#3高备变接于焦电220KV母线，其中#2、#3高备变相互备用。低压厂用电接线采用中央盘—车间盘接线方式。设计中对厂用负荷进行统计，根据计算结果选择厂用变压器；在进行短路计算后，对厂用电器设备进行了选择。

Abstract
Jiaozuo plant directly from the generator power plant in exports teaching, the use of the high-voltage transformer plant to plant by-bus bar electricity. To limit short-circuit current level of a low voltage transformer plant using high pressure to split winding split transformers; Plant a single mother with sub-bus bar connections, including two mutually spare no link between the bus bar. Six units were installed three start / standby transformers, then #1 change in the focus of a high-110KV bus bar, #2 and #3 high a change in focus to electricity 220KV bus bar, which #2 and #3 high mutual standby for change. Low voltage electrical wiring plant used the site-workshop plate wiring. Plants used for the design load statistics, according to calculations by choosing plant transformer; In short circuit calculation, the electrical equipment used to plant a choice. 计算机毕业设计----德维在线 www.devay.net
