The utility model relates to a 110kV movable substation, but the 110kV movable substation of a modularization split especially belong to electric wire netting equipment technical field. 110kV vehicle -mounted movable type transformer substation adopts the three -circuit transformer, and the electric pressure is 110kV35kV10kV. This 110kV movable substation entire system is by two combination formula platform trailer: transformer car and power distribution vehicle constitute, wherein the transformer car can be HGIS module and transformer module by the split, power distribution vehicle can be 35kV power distribution vehicle module and 10kV power distribution vehicle module by the split, and each module both can the independent utility also can be nimble the combination use, control between above each module and communication cable's connection all adopt the mode of quick plug head to make things convenient for high -speed joint and use between each module, put into operation and insert the electric wire netting in the scene of flexibility fast, and the operation maintenance is simply convenient.
