[0002] A medium-voltage switchgear is an electrical device used in a power distribution system, mainly for controlling, protecting, and distributing medium-voltage electricity. Medium-voltage switchgears are usually used in medium-voltage power distribution systems.

[0003] In recent years, the overall prefabrication of distribution switchgear cabinets has become increasingly popular. After the cabinets are fully prefabricated and integrated, the medium-voltage switchgear is arranged as a whole. The cabinet body of the medium-voltage switchgear is installed in a skid-block manner, that is, a row of cabinets (medium-voltage switchgear, control cabinets, etc.) are installed on an integral base and arranged in the form of such an integral skid block.

[0004] When an integrated structure is adopted, it is relatively difficult to connect the grounding wire at the lower end of the medium-voltage switchgear. Wiring needs to be carried out after the cabinet body of the skid block is installed. However, due to the influence of the overall quality, its layout is relatively difficult. For this reason, an integrated prefabricated structure of a medium-voltage switchgear skid block is proposed to solve the above-mentioned problems. Utility Model Content

[0006] To achieve the above object, the present application provides the following technical solution: An integrated prefabricated structure of a medium-voltage switchgear skid block, comprising a base, a prefabricated frame located on the base, and a cabinet body built in the prefabricated frame. A door bracket is fixedly installed at the top of the prefabricated frame, an installation frame is preset on the door bracket, a bottom cabinet is slidably installed in the base, a push spring is installed between the bottom cabinet and the base, and a locking structure is arranged in the base;

[0007] The locking structure includes a block rotatably installed inside the base and a reset member connected to the block.

[0008] Further, there are several cabinet bodies, and several cabinet bodies are installed on the base in the form of skid blocks, and a 300-mm-wide hollow area is reserved between the cabinet body and the base.

[0009] Further, reinforcing bars are fixedly installed at the four top corners of the prefabricated frame, and the reinforcing bars and the right-angle ends of the prefabricated frame surround to form a right-angled triangle.

[0010] Further, a copper bar is also preset between the cabinet body and the door bracket for connecting the cabinet body. A door panel is fixedly installed at the top of the door bracket, and a bridge bracket is also fixedly installed on the door bracket.

[0011] Further, the base is divided into upper and lower spaces, the bottom cabinet slides relative to the upper space, the push spring is located in the lower space and one end is fixedly connected to the inner wall of the base, and the other end is fixedly installed with a slider fixedly connected to the bottom cabinet.

[0012] Further, one end of the clamping block is bent in an L shape and abuts against the bottom cabinet, and a clamping groove corresponding to the clamping block is formed at the bottom of the bottom cabinet.

[0013] Further, the reset member includes a connecting handle fixedly installed in the base and a reset spring installed between the connecting handle and the clamping block.

[0014] Further, an extension plate is fixedly installed on the outside of the clamping block, and the extension plate extends in an L shape to the outside of the base.

[0015] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0016] The prefabricated integrated structure of the medium-voltage cabinet pry block is installed by setting a base, a prefabricated frame and a cabinet body, realizing the factory prefabrication of the whole row of cabinets. By setting a door bracket to install a bridge bracket and an installation frame, the overall integration is convenient, reducing on-site construction. By installing a bottom cabinet at the connection of the cabinet body below the base, and connecting the grounding wire through the movable loading of the bottom cabinet, the connection of the integrated structure is further facilitated, improving the convenience of on-site use.

Among them, there are several cabinet bodies 5, and the several cabinet bodies 5 are installed on the base 1 in the form of skids. A 300-mm-wide hollow area is reserved between the cabinet body 5 and the base 1 for placing control cable trays, weak-current cable trays, and fire cut-off cable trays, and unified aggregation and control are carried out through the control, weak-current, and fire cut-off cables in the base 1 to achieve the connection of the control, weak-current, and fire cut-off cable trays of the whole control cabinet to the outside or between AB circuits.

[0023] Preferably, reinforcing rods 3 are fixedly installed at the four top corners of the prefabricated frame 2. The reinforcing rods 3 and the right-angle ends of the prefabricated frame 2 surround to form a right-angled triangle, so as to improve the overall stability of the prefabricated frame 2.

[0024] In this embodiment, a door support 4 is fixedly installed at the top of the prefabricated frame 2, and an installation frame 9 is preset on the door support 4 for reserving installation spaces for lighting cable trays, control cable trays, and fire cable trays.

[0025] It should be noted that a copper bar 8 is also preset between the cabinet body 5 and the door support 4 for connecting the cabinet body 5. A door panel 6 is fixedly installed at the top of the door support 4, and a cable tray support 7 is also fixedly installed on the door support 4. Through the cable tray support 7, it is convenient to integrate the temperature and humidity sensors.

[0026] Additionally, a cross-connect cable tray routing is reserved between the two sides of the door support 4 for on-site quick splicing, which can penetrate all the cable tray routings in the whole room and completely solve the problem of suspending the cable trays in the distribution room;

[0027] A support for the door support 4 is preset at the top of the door support 4 to support the air duct, and the air duct can be directly laid on the corresponding door support 4 on site.

[0028] To facilitate the connection below the cabinet body 5, a bottom cabinet 10 is slidably installed in the base 1 in this embodiment, and a push spring 11 is installed between the bottom cabinet 10 and the base 1.

[0029] Furthermore, the base 1 is divided into upper and lower spaces. The bottom cabinet 10 slides relative to the upper space, and the push spring 11 is located in the lower space and one end is fixedly connected to the inner wall of the base 1, and the other end is fixedly installed with a slider 12 fixedly connected to the bottom cabinet 10.

[0030] In specific implementation, by sliding the bottom cabinet 10 relative to the base 1, the slider 12 fixedly connected to the bottom cabinet 10 can slide synchronously relative to the base 1, and at the same time, under the push of the push spring 11, it is convenient to pull the bottom cabinet 10 out of the base 1.

[0031] In this embodiment, a locking structure is provided in the base 1, and the locking structure includes a block 13 rotatably installed inside the base 1 and a reset member 14 connected to the block 13. One end of the block 13 is bent in an L shape and abuts against the base cabinet 10. A slot 15 corresponding to the block 13 is provided at the bottom of the base cabinet 10. By lifting the block 13 and extending it into the slot 15, the sliding of the base cabinet 10 relative to the base 1 can be restricted.

[0032] It should be noted that the reset member 14 includes a connecting handle fixedly installed in the base 1 and a reset spring installed between the connecting handle and the clamping block 13 . The reset spring provides a reverse thrust so that the clamping block 13 can be lifted up and snapped into the clamping slot 15 .

[0033] In order to facilitate the rotation of the pulling block 13 , an extension plate 16 is fixedly installed on the outside of the block 13 in this embodiment. The extension plate 16 is L-shaped and extends to the outside of the base 1 .

[0034] In a specific implementation, by pulling the extension plate 16 , the extension plate 16 can pull the clamping block 13 to rotate and disengage from the clamping slot 15 , so that the bottom cabinet 10 can be slidably adjusted relative to the base 1 .

[0035] The working principle of the above embodiment is:

[0036] A row of cabinets 5 are installed on the base 1 to form a tilting block structure, and the entire medium voltage cabinet is supported by a prefabricated frame 2, and a door bracket 4 is set to provide various brackets and sensors for installing and managing the medium voltage cabinet, so as to facilitate integration. The grounding wire and the cable are set in the base cabinet 10, and the setting is completed by sliding the base cabinet 10 to the base 1. After the card slot 15 under the base cabinet 10 moves to the position of the card block 13, the spring force of the reset member 14 pushes the card block 13 to rotate relative to the base 1, and the end of the card block 13 extends to the inside of the card slot 15, thereby limiting the sliding of the base cabinet 10 relative to the base 1, and the built-in of the base cabinet 10 is completed at this time.
