Substation three-dimensional design finished product verification system

The invention relates to a transformer substation three-dimensional design finished product verification system which comprises a three-dimensional design platform, a two-dimensional investigation design platform and a data transmission interface. The data transmission interface comprises a model information providing and checking module, a model automatic checking module and a message feedback module; the model capital provision verification module is used for generating a model capital provision verification request after a designer completes the design or modification of the model and sending the request to the model automatic verification module; the model automatic checking module is used for carrying out automatic checking and auxiliary collision checking on the received three-dimensional design finished product model of the transformer substation, and sending the three-dimensional design finished product model of the transformer substation and an obtained auxiliary checking file and an auxiliary collis
