The invention provides a 35kV assembling type intelligent transformer substation construction method. In the aspect of an automatic system, intelligent equipment which is set according to different functions in a whole station secondary system is replaced with wholly integrated type intelligent equipment, so that the integration degree of software and hardware equipment in the station is improved, the types and quantity of secondary intelligent equipment are reduced and investment and operation and maintenance difficulties are reduced. In the aspect of a construction mode, primary equipment and transformer substation buildings and structures are divided according to modules; standardized design, industrial production and field assembling construction manners are adopted, so that the field debugging working amount and the occupied area are reduced and the prominent problems of too high construction cost, difficulties of equipment transportation and addresses selection and the like are solved; and the 35kV assembling type intelligent transformer substation construction method can be easily popularized and applied in construction and modification of an intelligent transformer substation.
