Description

Technical Field

[0001] This invention belongs to the field of high-voltage distribution cabinet technology, specifically relating to a waterproof and shockproof high-voltage distribution cabinet. Background Technology

[0002] In modern power systems, high-voltage switchgear, as core equipment, undertakes the critical tasks of power distribution, control, and protection. Its stable operation is directly related to the reliability and security of the entire power grid. From large substations in cities to power centers in factories, high-voltage switchgear is ubiquitous and serves as a vital hub for ensuring the orderly transmission and use of electricity.

[0003] The heat dissipation method of existing high-voltage switchgear is mostly ventilation. In coastal areas, especially after rain, the air humidity is high. During the heat dissipation process, the outside humid air can easily enter the interior of the high-voltage switchgear. A large amount of water vapor can easily accumulate inside the high-voltage switchgear. When the humidity exceeds a certain threshold, the insulation material will absorb moisture, which will lead to a decrease in insulation performance. The insulation layer that can effectively block current becomes fragile, which greatly increases the risk of short circuit and electric shock, affecting the safety of equipment use and the reliability of power supply.

[0017] Preferably, the front of the high-voltage distribution cabinet body is sealed with a cabinet door, and instruments and operating buttons are installed on the cabinet door.

[0018] (3) Beneficial effects

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. In the above solution, a dehumidification box and an alternating dehumidification component are installed on the back of the high-voltage distribution cabinet. When in use, the moisture-absorbing cotton on one side of the alternating dehumidification component is located inside the through hole, and the moisture-absorbing cotton on the other side is located outside the through hole. The ventilation component blows the outside air from the air guide component to the bottom of the high-voltage distribution cabinet. At this time, the dust in the humid air is intercepted by the filter screen on the left side, and the moisture is absorbed by the moisture-absorbing cotton, thereby preventing condensation inside the high-voltage distribution cabinet during ventilation and heat dissipation, greatly reducing the risk of short circuit and electric shock, and improving the safety of equipment use and the reliability of power supply.

[0021] 2. In the above scheme, the drive motor is started to rotate the partition and support cylinder 180 degrees. During the rotation of the support cylinder, the moisture-absorbing cotton on the left and right sides can be swapped, so as to avoid the moisture-absorbing cotton on the left side becoming saturated after long-term use and can continue to absorb moisture. At the same time, the partition can drive the disc to rotate during the rotation of the disc. During the rotation of the disc, the crossbar can be moved to the right through the eccentric column and connecting rod. During the movement of the crossbar, the cylinder and operating rod can be moved upward through the inclined hole. During the upward movement of the operating rod, the left side of the air guide plate can be rotated upward, so that the air is blown to the inner top of the high-voltage distribution cabinet body, and the heat dissipation of the internal components is more uniform.

[0022] 3. In the above solution, a ventilation and drying pipe is installed at the top back of the high-voltage distribution cabinet. During the dehumidification process, the air inside the high-voltage distribution cabinet blows along the ventilation and drying pipe to the moisture-absorbing cotton on the right side. This accelerates the airflow and evaporates the moisture absorbed by the moisture-absorbing cotton for reuse. The filter component is located inside the moisture-absorbing component, and the ventilation and drying pipe can blow the dust on the filter component out in the opposite direction, avoiding blockage after long-term use and improving the ventilation and heat dissipation effect.

Detailed Implementation

[0034] An embodiment of the present invention provides a waterproof and shockproof high-voltage distribution cabinet, including a high-voltage distribution cabinet body 1. A dehumidification box 2 is fixedly connected to the bottom of the back of the high-voltage distribution cabinet body 1. An alternating dehumidification component 3 is provided on the right side of the dehumidification box 2. A ventilation drying pipe 4 is installed at the top of the back of the high-voltage distribution cabinet body 1. The other end of the ventilation drying pipe 4 extends to the alternating dehumidification component 3. An air exchange component 5 is provided on the upper surface of the dehumidification box 2. The dehumidification box 2 is connected to the high-voltage distribution cabinet body 1 through a vent 6. An air guide component 7 is provided at the vent 6.

[0035] The alternating dehumidification assembly 3 includes a through hole 8 on the back of the dehumidification box 2, which is flush with the inner wall of the dehumidification box 2. A support cylinder 9 is rotatably connected inside the through hole 8. The support cylinder 9 rotates clockwise from the top along the pivot 704. The support cylinder 9 is a cylindrical structure. The outer surface of the support cylinder 9 is rotatably fitted with the inner wall of the through hole 8. A partition 10 is fixedly connected between the inner walls of the front and rear sides of the support cylinder 9. Two moisture-absorbing assemblies 11 are fixedly connected to the left and right sides of the support cylinder 9, which are located inside and outside the through hole 8, respectively. A ventilation and drying pipe 4 is used to ventilate and dry the moisture-absorbing assemblies 11 outside the through hole 8. A drive motor 12 is fixedly connected to the upper surface of the dehumidification box 2. The drive motor 12 is used to make the two moisture-absorbing assemblies 11 work alternately.

[0036] like Figure 3 and Figure 8 As shown, in this embodiment, a filter assembly 13 is installed inside the moisture absorption assembly 11. Both the moisture absorption assembly 11 and the filter assembly 13 are arc-shaped structures. The air blown out by the ventilation drying pipe 4 can blow the dust on the right filter assembly 13 out in the opposite direction, avoiding blockage after long-term use and improving the ventilation and heat dissipation effect.

[0037] like Figure 7 and Figure 8 and Figure 9 As shown, in this embodiment, stepped mounting grooves 901 are provided on both the left and right sides of the support cylinder 9. Two slots 902 are provided on the inner wall of the mounting grooves 901. The mounting grooves 901 are opened downward from the left and right sides of the support cylinder 9, and clearance grooves are provided on both sides of the top end so that the cover plate 904 is flush with the upper surface of the support cylinder 9 after it is fixed. The slots 902 extend from the front and rear sides of the mounting grooves 901 to the bottom. The moisture absorption component 11 includes a first frame 1101 and moisture absorption cotton 1102 installed on the first frame 1101. The filter component 13 includes a second frame 1301 and a filter screen 1302 installed on the second frame 1301. The first frame 1101 and the second frame 1301 are respectively inserted into the two slots 902. The top end of the mounting groove 901 is fixedly connected to the cover plate 904 by countersunk screws 903. By removing the countersunk screws 903 and the cover plate 904 on the outside of the support cylinder 9, the moisture absorption component 11 and the filter component 13 can be removed and replaced, making maintenance more convenient.

[0038] like Figure 2 and Figure 5 As shown, in this embodiment, the ventilation and drying pipe 4 is fixedly connected to the top of the back of the high-voltage distribution cabinet body 1 through the conical cylinder 401, and the other end of the ventilation and drying pipe 4 is fixedly connected to the arc-shaped branch pipe 402 and equipped with an air outlet 403; in this way, the air outlet 403 can blow the air blown out of the high-voltage distribution cabinet body 1 toward the moisture-absorbing cotton 1102 on the right side to ensure the drying effect.

[0039] like Figure 5 and Figure 6 As shown, in this embodiment, a heater 404 is installed on the ventilation drying pipe 4, and an electric heating wire is installed inside the heater 404; the electric heating wire heats the air blown out of the high-voltage distribution cabinet body 1, thereby improving the drying speed and drying effect of the moisture-absorbing cotton 1102.

[0040] like Figure 2 and Figure 7 As shown, in this embodiment, the support cylinder 9, the partition plate 10 and the cover plate 904 are all in contact with the inner walls of the upper and lower sides of the through hole 8. The support cylinder 9 has a circular structure and its outer surface is in contact with the inner walls of the front and rear sides of the through hole 8. In this way, the support cylinder 9 forms a sealed air duct between the partition plate 10 and the two moisture absorption components 11 on the left and right.

[0041] like Figure 2 and Figure 3 As shown, in this embodiment, the ventilation assembly 5 includes an air duct 501 fixedly connected to the upper surface of the dehumidification box 2. A fan 502 is installed inside the air duct 501. One end of the air duct 501 is connected to the dehumidification box 2 through an air outlet 503. A protective net 504 is installed at the other end of the air duct 501. The air outlet 503 is located between the partition 10 and the moisture absorption assembly 11. By starting the fan 502, external air enters the interior of the dehumidification box 2 through the protective net 504 and the air outlet 503, and then passes through the filter 1302 on the left side and the moisture-absorbing cotton 1102 to ensure ventilation and heat dissipation.

[0042] like Figure 2 , Figure 3 and Figure 5As shown, in this embodiment, the air guide assembly 7 includes multiple air guide plates 701 rotatably connected to the front and rear sides of the opening 6. A through groove 702 is provided on the right side of each air guide plate 701. An operating rod 703 is rotatably connected to the through groove 702 via a pin. The output end of the drive motor 12 is fixedly connected to the upper surface of the partition 10. A rotating shaft 704 is fixedly connected to the lower surface of the partition 10. The output end of the rotating shaft 704 is used to move the operating rod 703 up and down. The interior of the dehumidification box 2 has an L-shaped structure. The bottom end of the rotating shaft 704 is located outside the dehumidification box 2 and is fixedly connected to a disc 705. A connecting rod 707 is rotatably connected to the lower surface of the disc 705 via an eccentric column 706. The other end of the connecting rod 707 is rotatably connected to a crossbar 708 via a pin. The other end of the crossbar 708 is slidably inserted into the interior of the dehumidification box 2 and has an oblique hole 709. The crossbar 708 can slide laterally. 709 is opened on the front of the crossbar 708 inside the dehumidification box 2, and the oblique hole 709 penetrates the rear side of the crossbar 708. The left end of the oblique hole 709 gradually decreases downward. The bottom end of the operating rod 703 is fixedly connected to the cylinder 710, which is located inside the oblique hole 709. The ventilation component 5 blows external air from the air guide component 7 to the inner bottom of the high-voltage distribution cabinet body 1. During the rotation of the support cylinder 9, it can drive the disc 705 to rotate. During the rotation of the disc 705, the crossbar 708 can be moved to the right through the eccentric column 706 and the connecting rod 707. During the movement of the crossbar 708, the cylinder 710 and the operating rod 703 can be moved upward through the oblique hole 709. During the upward movement of the operating rod 703, the left side of the air guide plate 701 can be rotated upward, so that the air is blown to the inner top of the high-voltage distribution cabinet body 1, and the heat dissipation of the internal components is more uniform.

[0043] like Figure 1 and Figure 2 As shown, in this embodiment, a cabinet door 101 is sealed on the front of the high-voltage distribution cabinet body 1, and an instrument 102 and an operation button 103 are installed on the cabinet door 101; the sealed cabinet door 101 reduces the entry of external moisture into the interior of the high-voltage distribution cabinet body 1.

[0044] The technical solution provided by this invention involves setting a dehumidification box 2 and an alternating dehumidification assembly 3 on the back of the high-voltage distribution cabinet body 1. During use, the moisture-absorbing cotton 1102 on one side of the alternating dehumidification assembly 3 is located inside the through-hole 8, and the moisture-absorbing cotton 1102 on the other side is located outside the through-hole 8. Simultaneously, the fan 502 is activated to allow external air to enter the dehumidification box 2 through the protective mesh 504 and the air vent 503. The air then passes through the filter screen 1302 on the left side and the moisture-absorbing cotton 1102, and is blown towards the high-voltage distribution cabinet body 1 through the vent 6 and the air guide assembly 7. At the bottom, dust in the humid air is intercepted by the filter 1302, and moisture in the humid air is absorbed by the moisture-absorbing cotton 1102 on the left side. This prevents condensation inside the high-voltage distribution cabinet body 1 during ventilation and heat dissipation, greatly reducing the risk of short circuits and electric shocks, and improving the safety of equipment use and the reliability of power supply. After long-term use, the moisture-absorbing cotton 1102 on the left side will become saturated with moisture, for example, after each ventilation for 3-5 hours. At this time, the drive motor 12 is started to rotate the partition 10 and the support cylinder 9 180 degrees. During the rotation of the support cylinder 9, the moisture-absorbing cotton 1102 on the left and right sides can be swapped, thus continuously absorbing moisture. At the same time, the partition 10 can drive the disc 705 to rotate during the rotation. During the rotation of the disc 705, the crossbar 708 can be moved to the right through the eccentric column 706 and the connecting rod 707. During the movement of the crossbar 708, the cylinder 710 and the operating rod 703 can be moved upward through the inclined hole 709. During the upward movement of the operating rod 703, the left side of the air guide plate 701 can be rotated upward, thus... Air is blown towards the top of the high-voltage distribution cabinet body 1, and a ventilation drying pipe 4 is installed at the top of the back of the high-voltage distribution cabinet body 1. During the dehumidification process, the air inside the high-voltage distribution cabinet body 1 is blown along the ventilation drying pipe 4 towards the moisture-absorbing cotton 1102 on the right side, thereby accelerating the airflow to evaporate the moisture absorbed in the moisture-absorbing cotton 1102 for the next use. The filter assembly 13 is located inside the moisture-absorbing assembly 11, and the ventilation drying pipe 4 can blow the dust on the filter assembly 13 out in the opposite direction to avoid blockage after long-term use.

[0045] All technical features in this embodiment can be freely combined according to actual needs.

[0046] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.
