The invention discloses a method used for examining and repairing an intelligent device of an intelligent convergence control cabinet of a digital transformer substation. An in-situ intelligent operation device fixed in a convergence control cabinet is designed into an intelligent control rotation box body which is convenient to examine and repair, wherein the in-situ intelligent operation deviceis formed by combining an in-situ operation device (1) and an intelligent unit device (2); the method comprises the following steps: supporting racks (4) are arranged in the convergence control cabinet; rotary positioning grooves (9) are arranged on the two supporting racks; the intelligent control rotation box body is provided with a movable shaft (3), and both ends of the movable shaft respectively penetrate through the rotary positioning grooves (9) of the two supporting racks and are fixed by pin shafts; and a panel of the intelligent control rotation box body is fixed at a baffle plate (5) of a front cabinet body of the convergence control cabinet by screws. When a fault occurs and examination and repair, maintenance or replacement is needed, the invention has convenient installation, disassembly, examination, repair and maintenance, reduces the workload largely and enhances the working efficiency. The times of the power failure of high-pressure one-time equipment are reduced, and the reliability and the safety of power supplying are ensured.
