The slide 707 rises and then engages with the fixing groove 710 on the fixing bar 709 on the trolley-type circuit breaker 205, thereby limiting the trolley-type circuit breaker 205, effectively avoiding the movement of the trolley-type circuit breaker 205 when the trolley-type circuit breaker 205 is transferred, thereby improving the transfer effect.

[0055] When the present invention is in use, first, when it is necessary to inspect the busbar room 203, the cabinet door 310 of the instrument room 203 can be opened by a key, and the cabinet door 310 rotates on the installation frame 308 through the connecting shaft 309. After the cabinet door 310 is opened, the dial block 401 on the connecting block 307 is pushed downward, and the dial block 401 drives the limit block 402 to slide, the first spring 404 is compressed, and the limit block 402 is no longer engaged with the first limit groove 406 on the first limit strip 405. Then the supporting structure 5 is adjusted, and the side door 303 is rotated again. The side door 303 is rotated to be perpendicular to the side of the cabinet body 1, and then the wiring board 306 is pulled. The wiring board 306 drives the partition 301 to slide on the first slide rail 302, and the partition 301 drives the instruments and lines installed on the partition 301 to move together to the second slide rail 305 on the side door 303 to slide, and at the same time, the wiring board 306 drives the connecting block 307 to When the second slide rail 305 is moved, the wiring board 306 contacts the second limit strip 408 on the side door 303, and then the shift block 401 is released, the first spring 404 is reset, and then the limit strip 402 is driven to engage in the second limit groove 409 on the second limit strip 408, thereby fixing the wiring board 306 and the partition 301, so as to avoid the partition 301 from sliding freely and blocking the field of vision when repairing the busbar room 203, and the wiring board 306 is used to connect the wires of the instrument on the partition 301 and the electronic display screen on the cabinet door 310, so as to improve the rationality of wiring, and at the same time avoid the partition 301 from pulling the wires when moving, thereby protecting the wires, and the setting of the guide shaft 403 improves the stability of the sliding of the limit strip 402, and at the same time effectively avoids the deviation of the first spring 404;

[0056] Then, before flipping the side door 303, the lifting block 506 on the support bar 503 must be slid first. The lifting block 506 slides and then drives the card block 507 to slide. The second spring 510 is compressed, and the card block 507 is no longer engaged with the first card slot 508 on the cabinet body 1. At this time, the lifting block 506 can be grasped to drive the support bar 503 to rotate. The support bar 503 then drives the fixing sleeve 502 to rotate. The fixing sleeve 502 rotates and then drives the limiting shaft 501 to rotate. After the limiting shaft 501 rotates ninety degrees, the side door 303 can be pulled, and the limiting shaft 501 slides out of the notch 504 on the cabinet body 1. At this time, the side door 303 can be rotated. The side door 303 rotates around the rotating shaft 304, and the support block 505 on the cabinet 1 initially supports the side door 303. Then, the angle of the support bar 503 is adjusted, and the support bar 503 is aligned with the mounting block 511 on the cabinet 1. Then, the lifting block 506 is released, and the second spring 510 is reset to drive the clamping block 507 to engage in the second clamping groove 512 on the mounting block 511. The support bar 503 and the cabinet 1 and the side door 303 form a triangular structure, which improves the stability of the side door 303. The setting of the guide column 509 improves the sliding stability of the clamping block 507 and effectively prevents the second spring 510 from running off.

[0057] Secondly, when it is necessary to fix the transfer trolley 9 on one side of the cabinet 1, it is only necessary to align the connecting strip 601 with the slot 603 on one side of the cabinet 1, and then press the pressure rod 607 on the handle 602, the pressure rod 607 drives the pressure strip 606 to slide, the third spring 609 is compressed, and at the same time the pressure strip 606 drives the positioning block 604 to retract into the interior of the connecting strip 601, and then the connecting strip 601 is inserted into the slot 603. After the connecting strip 601 is inserted into the slot 603, the pressure rod 607 is released, the third spring 609 is reset and then the positioning block 604 is engaged into the positioning groove 605 on the cabinet 1, thereby fixing the transfer trolley 9 on one side of the cabinet 1, and the setting of the guide strip 608 improves the stability of the sliding of the pressure strip 606, and effectively prevents the third spring 609 from running off;

[0058] Finally, when the trolley-type circuit breaker 205 needs to be slid out of the trolley chamber 201, the handwheel 703 on the transfer trolley 9 is first turned. The rotation of the handwheel 703 drives the screw 704 to rotate. The rotation of the screw 704 drives the slide plate 705 to slide. The sliding of the slide plate 705 drives the position of the guide groove 801 to change, and then drives the installation shaft 802 to roll inside the guide groove 801, thereby driving the angle of the driving bar 803 to change. The driving bar 803 rotates on the fixed shaft 804, thereby driving the connecting rod 805 to rotate. The rotation of the connecting rod 805 drives the guide plate 806 to rotate. The two guide plates 806 rotate and open. Therefore, when the trolley-type circuit breaker 205 is transferred to the transfer trolley 9, it is guided by the guide plate 806 and will accurately dock with the guide rail 702 on the transfer trolley 9 to avoid collision. Track, and the movement of the slide plate 705 will drive the roller 706 to move, and the roller 706 will then roll inside the driving groove 708 on the slide 707, thereby driving the slide 707 to slide downward, preventing the slide 707 from affecting the movement of the trolley-type circuit breaker 205 on the transfer vehicle 9. When the trolley-type circuit breaker 205 moves to the position of the baffle 701, the hand wheel 703 is rotated in the opposite direction, thereby driving the screw 704 to rotate in the opposite direction, and the slide plate 705 slides in the opposite direction, thereby driving the guide plate 806 to reset, and at the same time driving the slide 707 to rise. The slide 707 rises and then engages with the fixed groove 710 on the fixed bar 709 on the trolley-type circuit breaker 205, thereby limiting the trolley-type circuit breaker 205, effectively preventing the trolley-type circuit breaker 205 from moving when the trolley-type circuit breaker 205 is transported, thereby improving the transportation effect.
