[0002] High-voltage switchgear refers to the equipment used for switching, controlling or protecting in power generation, transmission, distribution, power conversion and consumption in power systems. A complete set of switchgear is a combination of all the parts and components involved in a complete set of switchgear. Generally, a 10kV high-voltage complete set of switchgear needs to undergo an AC withstand voltage test before the equipment is put into operation, so as to ensure the safety of the operation of the high-voltage complete set of switchgear.

[0003] A Chinese patent with publication number CN217281708U was searched and disclosed a high-voltage complete switch cabinet with a cabinet splicing structure.

[0004] The utility model includes a cabinet box and a cabinet door, a circuit breaker is arranged in the middle of the inner side of the cabinet box, and an instrument room is arranged on the inner top of the cabinet box, a limit seat is installed on one side of the outer surface of the cabinet box; an insert block is installed on the side of the outer surface of the cabinet box away from the limit seat, and a connection hole is opened at one end of the insert block. The high-voltage complete switch cabinet with a cabinet body splicing structure slides and docks the insert block on the side of one cabinet box with the limit seat on the side of another cabinet box, so that the slide groove inside the limit seat performs a limit connection on the insert block, and then the locking pin at one end of the limit seat is rotated to be threadedly connected with the connection hole at one end of the insert block, so that the two cabinet boxes can be stably spliced, and the splicing gap between the two adjacent cabinet boxes can be blocked by the sealing side plate and the sealing top plate, and the rotating connecting sleeve and the connecting column are threadedly connected, so that the through hole at the bottom of the connecting sleeve passes through the bracket and is supported on the ground.

[0005] However, this patent still has the following problems: after the switch cabinets on both sides are combined and spliced ​​together, there will still be a certain gap between the switch cabinets, which will still make it easy for foreign matter and dust to enter the gaps. At the same time, these gaps will also occupy a certain space, thereby increasing the overall space occupied by the combined switch cabinets. In addition, the bolts used to fix the switch cabinets on both sides are located in the gaps, which will make it inconvenient for operators to install and difficult to meet usage requirements.

[0023] The switch cabinet body 1 can be moved by the self-locking universal wheel 2, and after the movement is completed, the self-locking universal wheel 2 can be locked to prevent the switch cabinet body 1 from moving. When the switch cabinet bodies 1 on both sides are spliced ​​with each other, the switch cabinet bodies 1 on both sides are placed in parallel, and then the switch cabinet body 1 on the right side is moved to the left, so that the first limit frame 7 can enter the limit shell 6. At this time, the surface of the limit shell 6 will contact the inclined surface of the wedge block 9, so that the wedge block 9 can move upward by contacting its own inclined surface with the surface of the limit shell 6, so that the spring 8 can be compressed and deformed, so that the first The limit frame 7 can pass through the wedge block 9, and after the surfaces of the switch cabinet bodies 1 on both sides are attached, the spring 8 will use its own elastic force to make the wedge block 9 enter the first limit frame 7, so that the first limit frame 7 can be limited. During this period, the second limit frame 13 will enter the combination shell 14, and then the clamping plate 15 will be inserted into the second limit frame 13 and the limit groove 16 inside the combination shell 14, so that the combination shell 14 and the second limit frame 13 can also obtain a limiting effect, so that the upper and lower sides of the switch cabinet bodies 1 on both sides can be limited and fixed, so as to achieve no contact between the switch cabinet bodies 1 on both sides after the combination. There is a gap, and no bolts are required, which can greatly speed up the installation, reduce on-site construction time, and improve work efficiency. At the same time, the seamless splicing design can provide a more stable structural support, reduce displacement or loosening caused by vibration or external force, and effectively isolate external environmental factors such as dust, moisture, corrosive gases, etc. from entering the splicing gap, thereby improving the reliability and safety of the entire power system. After the switch cabinet bodies 1 on both sides are attached and spliced, the limit plate 4 between the surfaces of the two switch cabinet bodies 1 is rotated so that the limit plate 4 on the surface of the left switch cabinet body 1 can enter the surface of the right switch cabinet body 1 The inside of the mounting seat 3 also allows the right limiting plate 4 to enter the inside of the left mounting seat 3, so that the switch cabinet bodies 1 on both sides can be further combined and limited through the limiting effect between the limiting plate 4 and the fixing plate 5, to prevent the surface separation of the switch cabinet bodies 1 on both sides after splicing. When the limit needs to be released on the top of the switch cabinet body 1, the connecting rod 10 is pulled upward through the operating panel 12 and rotated, so that the surface thread of the connecting rod 10 is connected to the inner wall of the nut 11, so that the wedge block 9 can obtain the positioning effect, so that the first limiting frame 7 can be normally taken out from the inside of the limiting shell 6.

[0024] Furthermore, a connecting shell 17 is fixed on the top of the wedge block 9, a limit block 18 is fixed on the inner wall of the connecting shell 17, a combination groove for matching the limit block 18 is opened on the surface of the connecting rod 10, and the limit block 18 is slidably connected to the inner wall of the combination groove;

[0025] The connecting rod 10 can rotate on the inner wall of the connecting shell 17 , and the limiting block 18 can also rotate on the inner wall of the combination groove at the same time, so that the connecting rod 10 will not be separated from the inside of the connecting shell 17 .

[0026] Furthermore, a guide rod 21 is provided on the top of the switch cabinet body 1, and a guide block 22 is fixed on the top of the switch cabinet body 1. One end of the guide rod 21 is provided in a semicircular structure, and a guide groove for the guide rod 21 to pass through is provided on the surface of the guide block 22;

[0027] When the switch cabinet bodies 1 on both sides are spliced ​​together, the guide rod 21 will first enter the guide block 22 so that the switch cabinet bodies 1 can obtain a guiding effect, thereby making it easier to splice the switch cabinet bodies 1 on both sides.

[0028] Furthermore, a slide groove 19 is provided on the inner wall of the limit housing 6, a slider 20 is fixed on the surface of the wedge block 9, and the slider 20 is slidably connected to the inner wall of the slide groove 19;

[0029] When the wedge block 9 moves, the slider 20 can slide on the inner wall of the slide groove 19, so that the slider 20 can limit the bottom position of the wedge block 9 to avoid contact between the first limit frame 7 and the non-inclined surface of the wedge block 9.

[0030] Furthermore, a connecting plate 23 is fixed to the surface of the first limiting frame 7, the second limiting frame 13 and the guide rod 21, and the connecting plate 23 is detachably connected to the surface of the switch cabinet body 1 by bolts;

[0031] By providing the connecting plate 23 , the first limiting frame 7 , the second limiting frame 13 and the guide rod 21 can be removed from the surface of the switch cabinet body 1 , so that they will not increase the space occupied by the switch cabinet body 1 at the edge.
