The invention relates to a transformer substation integrating primary equipment and secondary equipment. The transformer substation comprises a cement housing, a switch cabinet PT interval, a switch cabinet outgoing wire interval and a manhole. The automatic screen consists of two parts: a distribution type DTU interval and a power supply and acquisition unit wherein the distribution type DTU interval is arranged on the top of the switch cabinet outgoing wire interval. The cement housing at the upper part of the DTU interval is provided therein with an installation frame. The installation frame is provided therein with the power supply and acquisition unit. According to the invention, the transformer substation is such a substation that has an innovative design, experiences simple improvement and integrates primary equipment and secondary equipment. With the improvement in the structure of the automatic screen and the proper planning of the inner space of a currently available substation, under the condition that the current foundation is not altered, the automatic control function is added. The improvement is simple, allowing the substation to both meet the requirement of customers and to ensure the successful progress of construction without putting the construction cost high considerably.
