城网110kV变电所设计思路

针对城网改造工作中，由于城市人口密集，土地资源紧张给市区变电所建设带来的困难，提出了“线路－变压器组接线”、“内桥接线”和“单母线接线”３种接线方式，使变电所接线简单化。中介绍了采用室内化、多层布置和综合利用多功能建筑等方法，在公园附近建设城市中心变电所的实践，解决了市区变电所建设的诸多难题，同时对该变所的无人值班综合自动化系统作了简单介绍。

A CONSIDERATION ON DESIGN OF 110 kV URBAN SUBSTATIONS

In the renovation of urban power network the difficulty caused by insufficient land for building and dense population is always met in the construction of urban substation. In order to simplify the wiring of urban substation, in this paper three wiring modes are put forward, i.e., the wiring for line and transformer sets, the wiring for internal bridge and the wiring for single busbar. To solve the difficulties in the building up of urban substations, a practical experience of building up substation near the park at the centre of the city is presented, in which three ways such as indoor wiring and installation, multi-layer arrangement and comprehensive utilization of multifunction buildings are applied.
