When the high-voltage equipment cabinet is used, firstly, when the high-voltage equipment is initially installed in the cabinet body, the high-voltage equipment is installed on the movable carrier plate 154 at the corresponding position, then cables connected with the high-voltage equipment are led into the protective sleeve 23 from the cables and enter the cable integrating box 21, then the cables connected with the high-voltage equipment are wound (at least one turn is wound, and the swinging of the cables is prevented by utilizing the friction force between the cables and the cable combing rubber wheel 274), then the cables connected with the high-voltage equipment are wound on the cable combing rubber wheel 274 at the corresponding position (the cables in the cable integrating box 21 are reserved with a certain length so as to be matched with the cables later), then the cables pass through the cable guide grooves 22 at the corresponding position and enter the equipment accommodating box 11, and finally the cables are connected with the terminals of the high-voltage equipment at the corresponding position;

along with the operation of the high-voltage complete equipment, when a certain high-voltage equipment in the equipment accommodating box 11 has a fault, a worker comes to the front of the high-voltage complete equipment, and at this time, because the high-voltage equipment is overhauled, the high-voltage equipment needs to synchronously rotate to the outside of the equipment accommodating box 11 along with the access door, so that the worker does not need to rotate the handle 452, because the whole height of the whole lifting guide rod 459 is highest under the supporting action of the spring 4511, each linkage hook 4510 is just hung in the through hole of the linkage hanging plate 156 (when the access door is closed, the outer end of the linkage hanging plate 156 is located in the cavity 43 through the adapting groove 44), at this time, the worker can directly open the first access door 4 of the high-voltage equipment or the second access door 5 of the high-voltage equipment, and in the process of opening the access door, each movable carrier 154 can synchronously rotate along with the center of the hinged seat 153 until the high-voltage equipment of the movable carrier plate 154 rotates to the outside of the equipment accommodating box 11;

meanwhile, in the process that each movable carrier 154 rotates synchronously with the access door, the movable carrier 154 positioned at the uppermost layer stops applying an extrusion acting force to the travel switch 18, so that the travel switch 18 works to connect a circuit containing the electric telescopic rod 275 (the circuit is the most common series circuit and is not detailed here), so that the electric telescopic rod 275 is shortened, and further the integral frame formed by the plurality of transverse supporting rods 272 and the plurality of longitudinal supporting rods 273 moves upwards, and in the moving process, the sliding block 276 moves upwards along the direction of the guide sliding groove 271 by means of the roller 277, so that each cable combing rubber wheel 274 moves upwards synchronously, and further each cable is carried to move upwards integrally (a margin with enough length is reserved at the bottom of the cable integrating box 21), thereby providing cables for the rotation of high-voltage equipment;

at the moment, a worker can find the high-voltage equipment corresponding to the fault outside the whole cabinet body structure without stretching or drilling both hands and a body into the cabinet body, so that the fault high-voltage equipment can be quickly and conveniently overhauled, the overhauling efficiency can be ensured, and the safety of the worker in the overhauling process can be improved;

after the maintenance is finished, the operation is performed in the same manner, the worker closes the access door, each high-voltage device can synchronously rotate to the inside of the device accommodating box 11 along with the access door, after the high-voltage device rotates, the movable carrier plate 154 positioned at the uppermost layer applies the extrusion acting force to the travel switch 18 again, and in the same manner, the electric telescopic rod 275 can extend again, so that the cable is retracted;

when the purpose that the staff opened the access door is not for the maintenance of high-voltage equipment or other purposes, this moment the staff is before opening the access door, need anticlockwise rotation handle 452, because handle 452, door shaft 451, be fixed connection between the three of initial linkage board 453, consequently when handle 452 is rotatory, door shaft 451 can follow synchronous rotation, and on the same way, initial linkage board 453 also can rotate in step, let initial linkage board 453 use door shaft 451 to carry out anticlockwise rotation as the center of rotation, make the bottom of initial linkage board 453 shift up, and then drive monoblock vertical linkage board 455 and shift up, let upper linkage board 456 and lower linkage board rotate clockwise in step again, make whole lift guide arm 459 move down, link every linkage couple 4510 and all break away from linkage link plate 156 in step, thereby realized that every activity hook 154 all is not connected with the access door, open the access door this moment, for the in-process that the access door independently rotates, activity support plate 154 still is located the inside of equipment containing box 11, the practicality of whole cabinet body structure under the actual use has been improved.
