Description

Technical Field

[0001] The utility model belongs to the technical field of high-voltage power cabinets, and in particular relates to a high-voltage power cabinet with an insulating structure. Background Art

[0002] A high-voltage power cabinet refers to a combination of electrical control cabinets that provide power for the normal operation of the entire machine. Contactors, inverters, high-voltage cabinets, transformers and other electrical components are often installed inside it. The insulating shell formed by the insulating plates in the power cabinet can effectively isolate the conductive parts in the high-voltage electrical components, reduce the risk of electric shock, and improve safety of use.

[0003] Existing power components such as contactors, frequency converters, high-voltage cabinets, and transformers installed in a power cabinet are fixed on a mounting plate of the power cabinet by bolts or screws, so that the power components can maintain stability during use. After fixation, the power components are connected to the power cabinet through multiple sets of wires. However, when there are too many connected wires inside the power cabinet, it is easy for the wires to cross and entangle with each other, thereby forming a tangle. As a result, during later maintenance, it is necessary to untie the tangled lines and perform maintenance first, which increases the time and difficulty of maintenance. Utility Model Content

[0004] The purpose of the utility model is to provide a high-voltage power cabinet with an insulation structure to solve the problems raised in the above background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: a high-voltage power cabinet with an insulating structure, comprising:

[0006] A cabinet body, wherein a cabinet door is hingedly connected to the surface of the cabinet body via a hinge;

[0007] An insulating chamber is composed of a plurality of insulating plates assembled together and is used to insulate electrical equipment in a cabinet. A mounting plate is fixed in the insulating chamber by a fixing assembly. A plurality of wire fixing assemblies are provided on the surface of the mounting plate. The wires of the electrical equipment are clamped and fixed by arc-shaped clamping blocks of the wire fixing assemblies so that the wires are fixed to the surface of the mounting plate to prevent the wires from being entangled.

[0008] Preferably, the wire fixing assembly includes a fixed shell and a bolt. The fixed shell is fixedly connected to the surface of the mounting plate. An arc groove is provided in the fixed shell. Both sides of the arc clamping block are slidably connected to the sliding groove provided in the fixed shell through a slider. One end of the bolt is rotated to penetrate the fixed shell and then rotatably connected to the arc clamping block. Both sides of the arc clamping block are slidably connected to the sliding groove in the fixed shell through the slider, which can enhance the stability of the arc clamping block when it moves.

[0009] Preferably, the fixing assembly includes a mounting block and a threaded rod. The mounting blocks are provided in two groups and the two groups of mounting blocks are symmetrically arranged in the insulating chamber. Both sides of the mounting plate are slidably connected to the T-shaped grooves provided on the surface of the mounting blocks through T-shaped sliders.

[0010] Preferably, a movable groove is provided in one group of mounting blocks, and the threaded rod rotates through the movable groove and is rotatably connected to the inner wall of the mounting block. The surface of the threaded rod is connected to a clamping rod through a screw sleeve transmission, and the bottom of the clamping rod is slidably connected to the mounting block. The sliding connection between the bottom of the clamping rod and the mounting block can enhance the stability of the clamping rod when it moves.

[0011] Preferably, a clamping groove is provided on the surface of the T-shaped sliding block at one end of the clamping rod, and the clamping rod is engaged with the clamping groove.

[0012] Preferably, a plurality of insulating blocks are provided between the insulating chamber and the cabinet body, and a plurality of mounting holes are provided on the surface of the mounting plate, through which the power components can be screwed and fixed to the surface of the mounting plate.

After installation, the T-shaped sliders on both sides of the mounting plate can be slid and inserted into the T-shaped grooves on the surface of the mounting block, and the threaded rod is rotated. The threaded rod drives the clamping rod to move toward the end close to the T-shaped slider and contact the T-shaped slider so that the clamping rod is clamped with the clamping groove on the surface of the T-shaped slider. Therefore, after the power components are installed on the mounting plate, the mounting plate can be confined in the cabinet to prevent the mounting plate from moving or shaking, thereby enhancing the stability of the mounting plate after installation.

[0015] (2) After the power element is screwed and fixed to the surface of the mounting plate, one end of the wire is passed through the arc groove in the fixing shell and connected to the power element, and the bolt is screwed to move the bolt toward one end of the arc groove and drive the arc clamp block to move accordingly, so that the arc clamp block contacts the wire. Under the action of the continuously moving bolt, the arc clamp block clamps the wire in the arc groove, so that multiple groups of wires can be fixed separately through several wire fixing components on the surface of the mounting plate, thereby achieving the effect of wire management and avoiding the problem of too many wires being entangled with each other after being connected to the power element.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides Figure 1-4 A high-voltage power cabinet with an insulation structure is shown, comprising:

[0023] A cabinet body 1, wherein a cabinet door 2 is hingedly connected to the surface of the cabinet body 1 via a hinge;

[0024] The insulating chamber 3 is composed of a plurality of insulating plates assembled together and is used to insulate the electrical equipment in the cabinet 1. A mounting plate 5 is fixed in the insulating chamber 3 by a fixing component 4. A plurality of wire fixing components 6 are provided on the surface of the mounting plate 5. The wires of the electrical equipment are clamped and fixed by arc-shaped clamping blocks 7 of the wire fixing components 6 so that the wires are fixed to the surface of the mounting plate 5 to prevent the wires from being entangled.

[0025] The wire fixing assembly 6 includes a fixing shell 8 and a bolt 9. The fixing shell 8 is fixedly connected to the surface of the mounting plate 5. An arc groove 10 is provided in the fixing shell 8. Both sides of the arc clamping block 7 are slidably connected to the sliding grooves provided in the fixing shell 8 through sliders. One end of the bolt 9 rotates through the fixing shell 8 and is rotatably connected to the arc clamping block 7. One end of the wire passes through the arc groove 10 in the fixing shell 8, and the bolt 9 is screwed, so that the wire is clamped and fixed in the arc groove 10 by the arc clamping block 7.

[0026] The fixing assembly 4 includes a mounting block 11 and a threaded rod 12. The mounting block 11 is provided with two groups and the two groups of mounting blocks 11 are symmetrically arranged in the insulating chamber 3. The two sides of the mounting plate 5 are slidably connected to the T-shaped slide groove 14 provided on the surface of the mounting block 11 through T-shaped sliders 13. The T-shaped sliders 13 on both sides of the mounting plate 5 are slidably connected to the T-shaped slide groove 14, so that the mounting plate 5 can be slidably installed into the cabinet 1.

[0027] One group of mounting blocks 11 is provided with a movable groove 15, and the threaded rod 12 rotates to pass through the movable groove 15 and then is rotatably connected to the inner wall of the mounting block 11. The surface of the threaded rod 12 is connected to a clamping rod 16 through a threaded sleeve transmission, and the bottom of the clamping rod 16 is slidably connected to the mounting block 11. A clamping groove 17 is provided on the surface of the T-shaped slider 13 at one end of the clamping rod 16, and the clamping rod 16 is engaged with the clamping groove 17. The threaded rod 12 is rotated in the forward direction, and the threaded rod 12 drives the clamping rod 16 to move toward one end close to the T-shaped slider 13, and contacts the T-shaped slider 13 so that the clamping rod 16 is engaged with the clamping groove 17 on the surface of the T-shaped slider 13, so that the mounting plate 5 can be confined in the cabinet 1 after the power components are installed on the mounting plate 5.

[0028] A plurality of insulating blocks 18 are provided between the insulating chamber 3 and the cabinet 1, and a plurality of mounting holes 19 are provided on the surface of the mounting plate 5. By establishing a certain insulating distance between the insulating chamber 3 and the cabinet 1, leakage or short circuit faults such as electrical components are prevented from occurring during operation, thereby improving the safety and reliability of the equipment.

[0029] The high-voltage power cabinet with an insulating structure is constructed by taking the mounting plate 5 out of the cabinet body 1 and screwing the power element to the surface of the mounting plate 5 through the mounting holes 19. After installation, the T-shaped sliders 13 on both sides of the mounting plate 5 can be slidably inserted into the T-shaped slide grooves 14 on the surface of the mounting block 11, and the threaded rods 12 are screwed forward to rotate. The threaded rods 12 drive the clamping rods 16 to move toward one end close to the T-shaped slider 13 and contact the T-shaped slider 13 so that the clamping rods 16 are clamped with the clamping grooves 17 on the surface of the T-shaped slider 13. Therefore, after the power element is installed on the mounting plate 5, the mounting plate 5 can be limited to the cabinet body 1. The mounting plate 5 is prevented from moving or shaking, and the stability of the mounting plate 5 after installation is enhanced. When the mounting plate 5 needs to be removed from the cabinet 1 to replace and repair the power components, the wires on the surface of the power components can be disconnected, and the threaded rod 12 can be rotated in the reverse direction. The threaded rod 12 drives the clamping rod 16 to move toward the end away from the T-shaped slider 13, so that the clamping rod 16 is disengaged from the clamping groove 17 on the surface of the T-shaped slider 13, so that the mounting plate 5 can be pulled out of the T-shaped slide groove 14 in the two groups of mounting blocks 11, so that the mounting plate 5 can be removed, which is convenient for replacing and repairing the power components.

[0030] After the power element is screwed and fixed to the surface of the mounting plate 5, one end of the electric wire is passed through the arc groove 10 in the fixing shell 8 and connected to the power element, and the bolt 9 is screwed to make the bolt 9 move toward the end close to the arc groove 10 and drive the arc clamping block 7 to move accordingly, so that the arc clamping block 7 contacts the electric wire, and the arc clamping block 7 clamps the electric wire in the arc groove 10 under the action of the continuously moving bolt 9, so that multiple groups of electric wires can be fixed separately through the several wire fixing components 6 on the surface of the mounting plate 5, so as to achieve the effect of wire management and avoid the problem of too many wires being entangled with each other after being connected to the power element.
