設(shè)計摘要
本次設(shè)計為110KV變電所電氣初步設(shè)計，通過對系統(tǒng)及負荷分析，進行了電氣主接線選擇。110KV通過對線路-變壓器組單元接線和單母線接線方式進行比較，選擇雙母線接線方式。10KV通過對單母分段接線和雙母接線方式比較，選擇單母分段接線方式。根據(jù)電氣主接線，進行短路電流計算。本次電氣設(shè)備選擇采用無油化、少維護、安全可靠的設(shè)備，110KV選用LW35-110六氟化硫斷路器，主變壓器選用 SSZ10－M-6300/110型號的變壓器，10KV選用真空斷路器。對直流及所用電系統(tǒng)、繼電保護及自動裝置、過電壓保護及防雷接地進行了配置，并對避雷器進行了選擇。

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 .
