a second step; when internal heat exchange is carried out, the front side of a sliding plate (55) in a pressure water tank (51) is pressurized, the sliding plate (55) and a rubber plate (56) move towards the rear side, at the moment, cooling liquid in the pressure water tank (51) is extruded into a water outlet pipe (53), the cooling liquid enters a cooling tank (110) from the water outlet pipe (53), at the moment, the cooling tank (110) is filled with pressure, the cooling liquid seeps out from a gap cooling device and is cooled on the surface of a transformer body (7), when two movable plates (64) move towards opposite directions, under the action of a sealing sleeve (65), because a pressure supply pipe (12) is communicated between the two movable plates (64), when the two movable plates (64) move towards opposite directions, air between the two movable plates (64) is compressed, and enters between a one-way air pressure sleeve (11) and a two-way air pressure sleeve (15) from the pressure supply pipe (12), at the moment, the first rubber sliding plate (13) on the left side moves to the right side, the first rubber sliding plate (13) on the right side moves to the left side, the two second rubber sliding plates (16) in the middle bidirectional air pressure sleeve (15) move in opposite directions, and the gap cooling device is abutted against the transformer body (7) under the action of the first vertical plate (14) and the second vertical plate (17);

a third step; when the gap cooling device is abutted to the transformer body (7), when the gap cooling device is extruded with the transformer body (7), the sealing round block (125) and the adhesive plate (136) are simultaneously extruded with the outer wall of the transformer body (7), at the moment, the adhesive plate (136) moves inwards, the adhesive plate (136) drives the pressing rod (134) to move, at the moment, the upper cross rod (143) of the pressing rod (134) moves in the two spiral grooves (146), at the moment, the rotating sleeve (133) rotates on the supporting rod (132), at the moment, the rotating sleeve (133) rotates, the rotating sleeve (133) can further wind the pull ropes (135), the two pull ropes (135) can pull the two arc-shaped sealing strips (141) to move in opposite directions, at the moment, the two arc-shaped sealing strips (141) are separated from the overlapping state with the sealing round block (125), and when the sealing round block (125) is extruded, the upwarping rod (128) of the sealing round block (125) rotates on the rotating rod (127), at the moment, one end of the tilting rod (128) extrudes the extrusion spring (129), at the moment, the water outlet hole (142) and the arc-shaped sealing strip (141) are separated from a closed state, so that the cooling liquid in the interior is extruded on the surface of the transformer body (7) under the action of pressure, under the elastic action of the return spring (113), the joint plate (115) and the transformer body (7) are separated from a propping state, at the moment, under the elastic action of the return spring (144) and the extrusion spring (129), the rotary sleeve (133) rotates reversely, the pull rope on the rotary sleeve (33) is released, the tilting rod (128) restores to the original position, at the moment, the sealing round block (125) is sleeved in the water outlet hole, and the two arc-shaped sealing strips (141) and the sealing round block (125) are in a lap joint state, so as to seal the interior;

the fourth step; the cooling liquid is partly from dividing liquid hole (111) entering connecting hole (79) in, and gather in flow concentration cover (710), when transformer (76) is inside to be heated and twines the situation of high temperature like this, the cooling liquid can exchange inside heat, and gather in double-deck isolation cover (71) in flow distribution hole (78), under the effect of fin (74) and heat dissipation inner chamber (75), can carry out the heat dissipation with the cooling liquid and handle, radiating cooling liquid is retrieved from one-way resorption valve (52) under the effect of suction, accomplish a cooling cycle this moment, and also gather in flow concentration cover (710) from oozing the cooling liquid in the clearance cooling supply device, can quick radiating operation like this.
