The invention relates to the technical field of power equipment, in particular to an automatic height adjustment and calibration device for a cabinet door of a substation switch cabinet and a control method. A first telescopic marker post is vertically welded to a base of a hydraulic jack, and the top end of the first telescopic marker post is horizontally connected with a second telescopic marker post through a first connecting rod; the top of a piston of the hydraulic jack is fixedly connected with a Z-shaped lifting mechanism through a screw, a fourth telescopic marker post is vertically welded to the upper portion of the Z-shaped lifting mechanism, and the top end of the fourth telescopic marker post is horizontally connected with a third telescopic marker post through a second connecting rod. A first buzzer electrode is fixed on the first connecting rod; and a second buzzer electrode is fixed on the second connecting rod. The method has the beneficial effects that only two workers are needed, the working
