设计摘要
本次设计为110KV变电所电气初步设计，通过对系统及负荷分析，进行了电气主接线选择。110KV通过对线路-变压器组单元接线和单母线接线方式进行比较，选择双母线接线方式。10KV通过对单母分段接线和双母接线方式比较，选择单母分段接线方式。根据电气主接线，进行短路电流计算。本次电气设备选择采用无油化、少维护、安全可靠的设备，110KV选用LW35-110六氟化硫断路器，主变压器选用 SSZ10－M-6300/110型号的变压器，10KV选用真空断路器。对直流及所用电系统、继电保护及自动装置、过电压保护及防雷接地进行了配置，并对避雷器进行了选择。

Abstract
The article talks about the tentative electric desibn about 110KV transformer station , which selects the main electric wiring by analyzing the system and load .After comparing the wiring way of unit wiring and single bus bar of transformer , 110KV is suitable for using the later .After comparing the way of single bus bar and double wiring ,10KV is suitable for using the former . People calculate the electric current of short circuit according to main electric wiring . The safe equipments are used , which have no oil , don’t need repair . 110KV selects lw 35-110 circuit breaker , while 10KV selects vacuum one . It deploys the direct current and its system , automatic deice, over-voltage protection and so on , and selects the proper lightning arrester .
