Description

Technical Field

[0001] This utility model relates to the field of cable management devices, and more particularly to cable management devices for high-voltage switchgear. Background Technology

[0002] The cable management device for high-voltage switchgear is a device used to organize and manage the cable lines inside the high-voltage switchgear. Its function is to improve the standardization, safety and reliability of the high-voltage switchgear wiring and ensure the stable operation of the high-voltage system.

[0003] In existing high-voltage switchgear cable management devices, when cables are concentrated in the management area, the airflow channels are occupied to varying degrees, reducing the effective cross-sectional area of ​​the airflow. This leads to increased resistance when air flows within the device, making it difficult for the air to circulate quickly and evenly in various areas. Consequently, it restricts the effective transfer and dissipation of heat, preventing the heat in that area from being discharged in a timely manner, thus affecting the overall heat dissipation effect of the device.

[0004] Therefore, to address the problems of existing high-voltage switchgear cable management devices where airflow channels are obstructed, the effective cross-sectional area of ​​airflow is reduced, airflow resistance is increased, and rapid and uniform airflow is difficult to achieve in all areas, resulting in limited heat transfer and dissipation and inability to expel heat in a timely manner, thus affecting the overall heat dissipation effect, a new high-voltage switchgear cable management device can be designed. This device uses three sets of vertical cable trays linearly installed on the inner walls of two sets of side panels to provide an orderly arrangement space for vertical cables, avoiding the haphazard stacking of cables that occupy too much airflow channel. The guide channel connected to one side of the vertical cable trays can guide the orderly flow of hot air. The heat dissipation backplate, which is installed through the three sets of filter plates on the outside of the two sets of side panels, provides a channel for the exhaust of hot air. Utility Model Content

[0005] To overcome the problems of existing high-voltage switchgear cable management devices where airflow channels are blocked, the effective cross-sectional area of ​​airflow is reduced, airflow resistance is increased, making it difficult to circulate quickly and evenly in all areas, limiting heat transfer and dissipation, and failing to exhaust heat in a timely manner, thus affecting the overall heat dissipation effect.

[0006] The technical solution of this utility model is as follows: a cable management device for a high-voltage switchgear, comprising a horizontal plate, side plates, and cable routing plates; two sets of side plates are symmetrically installed at the bottom of the horizontal plate for organizing vertical cables and improving overall ventilation; cable routing plates for organizing horizontal cables are symmetrically installed between the two sets of side plates; three sets of vertical cable routing grooves are linearly installed on the inner walls of both sets of side plates; a guide groove is installed on one side of each of the three sets of vertical cable routing grooves; three sets of filter plates are installed through the outer surfaces of both sets of side plates at the corresponding locations of the guide grooves on the inner walls; and a heat dissipation backplate is installed through the outer surfaces of both sets of side plates between the three sets of filter plates.

[0007] Preferably, during the operation of the high-voltage switchgear, the horizontal plate serves as the basic support, with two sets of side plates symmetrically installed at its bottom. Three sets of vertical cable trays are linearly distributed on the inner wall of the side plates, in which vertical cables are placed to separate them. The cable trays symmetrically installed between the two sets of side plates are used for the arrangement of horizontal cables and guide their direction. When heat is generated inside the high-voltage switchgear, the hot air in the vertical cable trays will be guided through the flow channel connected on one side. At the same time, outside air enters through the filter plate corresponding to the flow channel on the outside of the side plate and the inner wall, flows along the flow channel, exchanges heat with the heat-generating components, and is then discharged through the heat dissipation back plate.

[0008] Preferably, both sets of side panels have through-holes on their exteriors, and the three sets of vertical cable trays have multiple sets of vertical cable tray holes linearly on their exteriors. The inner walls of the two sets of side panels have multiple sets of mounting slots from top to bottom between the three sets of vertical cable trays.

[0009] As a preferred embodiment, two sets of sliding rods are symmetrically installed on both sides of the horizontal plate, and each set of sliding rods has a mounting block at its top and a mounting groove at its bottom.

[0010] Preferably, each side of the mounting block is equipped with a mounting connection plate, and the outside of the mounting connection plate is provided with threaded holes at the four corners. The top of the horizontal plate is provided with three sets of wire harness holes.

[0011] Preferably, two sets of magnetic blocks are symmetrically installed at the top of the horizontal plate, and a power supply is installed at the top of the horizontal plate between the two sets of magnetic blocks.

[0012] Preferably, multiple sets of lighting lamps are linearly installed at the bottom of the horizontal plate, and the lighting lamps are electrically connected to the power supply.

[0013] Preferably, a cable marking groove is provided on the lower part of the outer side of the cable tray, and multiple sets of horizontal cable routing holes are provided linearly through the outer side of the cable tray.

[0014] The beneficial effects of this utility model are as follows: Three sets of vertical cable trays linearly installed on the inner walls of the two sets of side plates provide an orderly arrangement space for vertical cables, avoiding the random stacking of cables and occupying too much air circulation channel. The guide channel connected to one side of the vertical cable tray can guide the orderly flow of hot air. Compared with the irregular air flow in the prior art, this device can guide hot air to the heat dissipation area more smoothly, effectively solving the problem that air is difficult to circulate quickly and evenly in various areas, and greatly improving the efficiency of heat transfer and dissipation. Three sets of filter plates installed through the outer side of the two sets of side plates and corresponding to the inner wall guide channels can filter external dust and debris, preventing them from entering the device and blocking the air channel, ensuring smooth air circulation. The heat dissipation back plate installed through the outer side of the two sets of side plates between the three sets of filter plates provides a channel for hot air to be discharged. Compared with the unreasonable design of heat dissipation holes in the prior art, which are easily blocked, the filter plates and heat dissipation back plate of this device work together to ensure the normal entry and exit of air, so that heat can be discharged in time, effectively improving the overall heat dissipation effect.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-4In this embodiment, the cable management device of the high-voltage switchgear includes a horizontal plate 1, side plates 2, and cable routing plates 3. Two sets of side plates 2 are symmetrically installed at the bottom of the horizontal plate 1 for organizing vertical cables and improving overall ventilation. Cable routing plates 3 for organizing horizontal cables are symmetrically installed between the two sets of side plates 2. Three sets of vertical cable routing grooves 202 are linearly installed on the inner walls of both sets of side plates 2. A guide groove 206 is installed on one side of each of the three sets of vertical cable routing grooves 202. Three sets of filter plates 204 are installed through the outer surfaces of both sets of side plates 2 at locations corresponding to the guide grooves 206 on the inner walls. A heat dissipation backplate 203 is installed through the outer surfaces of both sets of side plates 2 between the three sets of filter plates 204. During operation of the high-voltage switchgear… At this time, the horizontal plate 1 serves as the basic support, and two sets of side plates 2 are symmetrically installed at its bottom. Three sets of vertical cable trays 202 are linearly distributed on the inner wall of the side plate 2, in which vertical cables are placed to achieve separation of vertical cables. The cable trays 3 symmetrically installed between the two sets of side plates 2 are used for the arrangement of horizontal cables and guide the direction of horizontal cables. When heat is generated in the high-voltage cabinet, the hot air in the vertical cable trays 202 will be guided through the guide channel 206 connected on one side. At the same time, the outside air enters through the filter plate 204 at the corresponding position of the guide channel 206 on the outside of the side plate 2 and the inner wall, flows along the guide channel 206, and after exchanging heat with the heat-generating components, it is discharged through the heat dissipation back plate 203.

[0022] Please see Figures 1-4 In this embodiment, both sets of side plates 2 have through-holes 201 on their exteriors, and the three sets of vertical cable trays 202 each have multiple sets of vertical cable tray holes 205 linearly formed on their exteriors. The inner walls of the two sets of side plates 2, located between the three sets of vertical cable trays 202, have multiple sets of mounting slots 207 formed from top to bottom. The through-holes 201 on the exteriors of both sets of side plates 2 greatly improve the convenience of device installation and expansion. During actual installation, bolts, screws, and other connectors can be used through the through-holes 201 to securely connect the side plates 2 to the high-voltage cabinet or other equipment components, ensuring the entire cable management device is firmly installed inside the high-voltage cabinet and preventing shaking or displacement during operation. To ensure the stability of the cable management device, two sets of sliding rods 102 are symmetrically installed on both sides of the horizontal plate 1. Each set of sliding rods 102 has a mounting block 103 at its top and a mounting groove 107 at its bottom. The two sets of sliding rods 102 symmetrically installed on both sides of the horizontal plate 1 facilitate the installation and adjustment of the entire cable management device. During installation, the sliding rods 102 can serve as a guide structure, allowing the cable management device to be smoothly connected and installed with other components of the high-voltage cabinet, reducing deviations during installation. At the same time, the sliding characteristics of the sliding rods 102 allow the cable management device to be flexibly adjusted within a certain range to adapt to different spatial layouts and installation requirements within the high-voltage cabinet, thus improving the versatility of the device.

[0023] Please see Figures 1-2In this embodiment, mounting connecting plates 104 are installed on one side of the mounting block 103. Threaded holes are drilled through the outer corners of the mounting connecting plates 104. Three sets of wire harness holes 105 are linearly drilled through the top of the horizontal plate 1. These three sets of wire harness holes 105 provide a dedicated channel for the arrangement of cable harnesses. When organizing cables, wire harnesses of different specifications and uses can pass through and be arranged in an orderly manner through these wire harness holes 105, avoiding random crossing and tangling of wire harnesses above the horizontal plate 1. This makes the entire cable wiring neater and more standardized, which not only facilitates subsequent... For continued maintenance and repair, two sets of magnetic blocks 101 are symmetrically installed at the top of the horizontal plate 1. A power supply 108 is installed between the two sets of magnetic blocks 101 at the top of the horizontal plate 1. The two sets of magnetic blocks 101 symmetrically installed at the top of the horizontal plate 1 provide convenience for temporarily fixing small metal parts or tools. During the installation, commissioning and maintenance of the high-voltage cabinet, staff can attach some small metal parts, tools, etc. to the magnetic blocks 101 to prevent them from being placed randomly in the high-voltage cabinet and lost. At the same time, it can also prevent small parts from falling and causing electrical faults. In addition, the magnetic blocks 101 can also help fix the overall device.

[0024] Please see Figures 1-4 In this embodiment, multiple sets of lighting lamps 106 are linearly installed at the bottom of the horizontal plate 1. These lamps 106 are electrically connected to the power supply 108. The multiple sets of lighting lamps 106 linearly installed at the bottom of the horizontal plate 1 and electrically connected to the power supply 108 provide ample lighting for the interior of the high-voltage cabinet. During cable wiring, inspection, or maintenance work, because the interior space of the high-voltage cabinet is complex and usually dimly lit, the lighting lamps 106 can illuminate every corner, allowing workers to clearly see the cable routing, wiring locations, and various components of the cable management device, greatly improving work efficiency and accuracy. Furthermore, this... The lighting fixtures 106 are positioned reasonably and installed at the bottom of the horizontal plate 1 to effectively prevent direct light from shining into the eyes of the staff and reduce visual fatigue, while also fully covering the area that needs to be operated. The cable tray 3 has a cable identification groove 301 on the lower part of its exterior. Multiple sets of horizontal cable holes 302 are linearly opened on the exterior of the cable tray 3. The cable identification groove 301 on the lower part of the exterior of the cable tray 3 facilitates the identification and management of cables passing through the cable tray 3. Staff can insert labels into the cable identification groove 301 to clearly mark the purpose, number, connected equipment and other information of each cable.

[0025] During operation, two sets of side plates 2 symmetrically installed at the bottom of the horizontal plate 1 have three sets of vertical cable trays 202 linearly installed on their inner walls, providing dedicated channels for vertical cables. During wiring, the vertical cables are placed orderly in the vertical cable trays 202, achieving separation and preventing tangling. Cables with special routes or requiring branching can pass through or enter via multiple sets of vertical cable holes 205 linearly opened on the outside of the vertical cable trays 202, making wiring more flexible and adaptable to the complex internal structure of the high-voltage cabinet. Cable trays 3 symmetrically installed between the two sets of side plates 2 are responsible for organizing horizontal cables. Horizontal cables are arranged along the cable trays 3, passing through multiple sets of horizontal cable holes 302 linearly opened on the outside of the cable trays 3. Different paths are selected according to actual layout requirements, avoiding cable compression and excessive bending due to wiring space limitations. At the same time, the cable identification groove 301 opened at the lower part of the outer side of the cable tray 3 makes it convenient for staff to insert labels to mark the cable's purpose, number and other information, which facilitates subsequent maintenance and troubleshooting. When the electrical equipment in the high-voltage cabinet generates heat during operation, the hot air rises and enters the vertical cable tray 202. The guide groove 206 connected to one side of the vertical cable tray 202 guides the hot air in an orderly manner, preventing it from accumulating in the vertical cable tray 202. External cold air enters through the filter plate 204 installed through the corresponding part of the guide groove 206 on the outer side of the side plate 2. The filter plate 204 filters out dust and debris. The cold air enters along the guide groove 206 and exchanges heat with the heated cables and electrical components. The heated air is then discharged to the outside of the high-voltage cabinet through the heat dissipation back plate 203 located between the three sets of filter plates 204, forming a circulating heat dissipation.

[0026] Through the above steps, when the high-voltage cabinet is running, the horizontal plate 1 serves as the basic support, and two sets of side plates 2 are symmetrically installed at its bottom. Three sets of vertical cable trays 202 are linearly distributed on the inner wall of the side plate 2, in which vertical cables are placed to achieve separation of vertical cables. The cable trays 3 symmetrically installed between the two sets of side plates 2 are used for the arrangement of horizontal cables and guide the direction of horizontal cables. When heat is generated in the high-voltage cabinet, the hot air in the vertical cable trays 202 will be guided through the guide channel 206 connected on one side. At the same time, outside air enters through the filter plate 204 at the corresponding position of the guide channel 206 on the outside of the side plate 2 and the inner wall, flows along the guide channel 206, and after exchanging heat with the heat-generating components, it is discharged through the heat dissipation back plate 203.
