Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a high-voltage power distribution cabinet. Background Art

[0002] There are many ways to install electrical components in high-voltage distribution cabinets. One of the solutions is suitable for installing electrical components in rows. The details are as follows: Use a crossbeam to fix the inside of the cabinet, and fix the electrical components to the crossbeam. However, the connection between the crossbeam and the cabinet usually uses a bolt and nut assembly to pass through the crossbeam, and use the bolt head and nut to clamp the crossbeam on the sheet structure. This is a friction pre-tightening solution. To improve stability, you can also directly use fasteners to penetrate the internal structure of the cabinet, or open new holes and pass the fasteners through the holes to completely fix the crossbeam on the cabinet, but this will damage the cabinet and there is also the possibility of screws coming loose.

[0019] A high-voltage power distribution cabinet comprises a high-voltage cabinet body 1 with front and rear openings. When the high-voltage cabinet body 1 is used for training purposes, the front and rear openings do not need to be sealed. When actually used, the front end of the high-voltage cabinet body 1 should be welded or fixedly connected to a metal profile by screws, and a cabinet door 13 is arranged at the rear opening. The high-voltage cabinet body 1 is fixedly connected to the right end of a hinge, and the left end of the hinge is fixedly connected to the rear end of the left part of the high-voltage cabinet body 1, so that the cabinet door 13 can be opened or closed relative to the high-voltage cabinet body 1. The cabinet door 13 can be detachably connected to the high-voltage cabinet body 1 by using conventional screw fasteners, or a padlock, a buckle and a pin.

[0020] Also included is a connection component, the connection component comprising:

[0021] Two longitudinal pieces 2 are respectively fixed to the left and right ends of the inner wall of the high-voltage cabinet body 1, each longitudinal piece 2 is provided with a vertical straight slot 3, and the longitudinal piece 2 is provided with an arc opening Ⅰ4 connected to the straight slot 3 and distributed longitudinally, and the arc opening Ⅰ4 is located on the left side of the straight slot 3; it also includes a connecting piece 5 attached to the front end of the longitudinal piece 2, and the rear end of the connecting piece 5 is provided with an arc opening Ⅱ6, and the direction of the arc opening Ⅱ6 is opposite to the direction of the arc opening Ⅰ4; it also includes a crossbeam Ⅰ7 attached to the rear end of the longitudinal piece 2, and the front end of the crossbeam Ⅰ7 is fixedly connected to two or four columns 8. When the number of columns 8 fixed to the crossbeam Ⅰ7 is two, and the two columns 8 are arranged one on the left and the other on the right, when the number of columns 8 fixed to the crossbeam Ⅰ7 is four, and the four columns 8 are located at the four corners of a virtual quadrilateral;

[0022] Combination Figure 4 and 5 A connecting piece 5 is used to connect the left part of the cross beam Ⅰ7 and the longitudinal piece 2 on the left side, and a connecting piece 5 is used to connect the right part of the cross beam Ⅰ7 and the longitudinal piece 2 on the right side, for a total of two connecting pieces 5; specifically, the left and right widths of the straight slot 3 are the diameters of the column 8, so that the column 8 can be completely withdrawn from the arc opening Ⅰ4 to the straight slot 3. During installation, the height of the cross beam Ⅰ7 is first determined by clamping the column 8 in the arc opening Ⅰ4, and then the connecting piece 5 is attached to the front end of the longitudinal piece 2, and the position of the arc opening Ⅱ6 and the arc opening Ⅰ4 is aligned. There is a one-to-one correspondence, so that any arc opening Ⅱ6 always has an arc opening Ⅰ4 that can cooperate with it, so that the two are located on a virtual circle, so that the arc opening Ⅱ6 and the arc opening Ⅰ4 are wrapped on the column 8, and finally the bolts are passed through the cross beam Ⅰ7, the column 8, the longitudinal piece 2 and the connecting piece 5. The head of the bolt rests on the front end surface of the connecting piece 5, and the tail of the bolt is located at the rear end of the cross beam Ⅰ7. The nut is screwed into the tail of the bolt and the nut rests on the rear end of the cross beam Ⅰ7, so that the cross beam Ⅰ7, the column 8, the longitudinal piece 2 and the connecting piece 5 are detachably connected.

[0023] The height of the crossbeam Ⅰ7 can be determined by installing it at different arc openings Ⅰ4. Compared with the traditional solution of using friction pre-tightening of pre-tightening parts, this connection method is more stable. Compared with the solution of using self-tapping screws to damage the cabinet, this method does not require special power tools, will not damage the cabinet, and is also convenient for disassembly, maintenance and replacement of electrical components.

[0024] Basic electrical components can be directly and detachably connected to the crossbeam Ⅰ7, but this solution is not suitable for the installation of professional complete sets of accessories. Therefore, the following solution is adopted:

[0025] The connecting piece 5 is an L-shaped structure, and a crossbeam II 9 is provided at the rear end of the longitudinal piece 2. A fastener passes through the crossbeam II 9 and the connecting piece 5 to achieve a detachable connection. After the spacing between the crossbeam II 9 and the crossbeam I 7 is determined, screws are driven into the crossbeam II 9 and the crossbeam I 7 to fix the crossbeam II 9, and then a T-shaped connector is inserted between the crossbeam II 9 and the connecting piece 5. The T-shaped connector is clamped by the crossbeam II 9 and the connecting piece 5, and then the T-shaped connector is fixed to the crossbeam II 9 and the crossbeam I 7 by screws or bolt and nut assemblies, and finally an electrical component such as a capacitor voltage divider is fixed to the T-shaped connector. The lightning arrester is fixed to the bottom of the high-voltage cabinet body 1 to be located directly below the crossbeam I 7, and the high-voltage cabinet body 1 is more suitable as a cable room.

[0026] Preferably, a cable winder is also included, and a mounting hole is provided on the cross beam Ⅰ7; the cable winder includes: a stud 10 inserted into the mounting hole, a nut against the front end of the cross beam Ⅰ7 is screwed into the front end of the stud 10, a center rod 11 is fixedly connected to the rear end of the stud 10, and a clamp 12 is fixedly connected to the upper and lower ends of the rear of the center rod 11, and there is a gap between the front end of the clamp 12 and the rear end of the stud 10, and the clamp 12 can be bent relative to the center rod 11, and there is a gap between the clamp 12 and the center rod 11. It is preferred to set the cable winders up and down as a group, and it is secondarily preferred to use them alone. When two cable winders are used, the cable is wound around the two center rods 11, and the clamp is used to limit the upper and lower ends of the wound cable; this solution replaces disposable nylon cable ties, does not need to be cut during installation and removal, is easy to use, and can make the cable not need to be tied to the arrester with a nylon cable tie.
