Description

Technical Field

[0001] This utility model relates to the technical field of heat-dissipating high-voltage switchgear, specifically a heat-dissipating high-voltage switchgear. Background Technology

[0002] High-voltage switchgear refers to electrical products used in power systems for switching, control, or protection in power generation, transmission, distribution, energy conversion, and consumption. High-voltage switchgear is categorized into several main types based on voltage levels ranging from 3.6kV to 550kV, including high-voltage disconnect switches and grounding switches, high-voltage load switches, high-voltage automatic reclosers and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices, and high-voltage switchgear itself. Existing high-voltage switchgear typically has ventilation holes on the cabinet to dissipate internal heat, allowing direct convection between the inside and outside of the cabinet. This makes it easy for dust from the outside air to enter the switchgear, potentially affecting the internal electrical components. Some existing high-voltage switchgear uses liquid cooling for heat dissipation, but the coolant used for liquid cooling tends to accumulate sediment after long-term use, which is difficult to clean. Therefore, we propose a heat dissipation-type high-voltage switchgear device to address the aforementioned problems. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-5This utility model provides a technical solution: a heat-dissipating high-voltage switchgear, including a cabinet body 1. A cabinet door 8 is provided on the surface of the cabinet body 1, and the door 8 is hinged to the cabinet body 1. A partition 9 is provided inside the cabinet body 1. Side plates 2 are provided on both sides of the cabinet body 1, and the side plates 2 are connected to the cabinet body 1 by bolts. A limiting rod 10 is fixedly connected to the side plate 2, and the limiting rod 10 is slidably connected to the partition 9. A fixing frame 3 is fixedly connected inside the cabinet body 1. Two sets of cooling pipes 13 are provided inside the cabinet body 1, and the fixing frame 3 is fixedly connected to the cooling pipes 13. The lower ends of the two sets of cooling pipes 13 are connected by a connecting pipe 5. A liquid storage tank 14 is provided above the cabinet body 1. A retrieval assembly 4 is provided inside the liquid storage tank 14. The retrieval assembly 4 includes an assembly slot 401, a lead screw 402, a slider 403, an assembly plate 404, an assembly block 405, an assembly frame 406, a filter screen 407, a moving block 408, and a storage slot 409. The liquid storage tank 14 is equipped with two sets of assembly slots 401, and a lead screw 402 is installed in the assembly slot 401 on the left side of the liquid storage tank 14. The lead screw 402 is threadedly connected to the slider 403, and the slider 403 is slidably connected to the assembly slot 401. The slider 403 is fixedly connected to one side of the assembly plate 404, and the other side of the assembly plate 404 is slidably connected to the assembly slot 401 on the right side of the liquid storage tank 14. The assembly plate 404 is slidably connected to the assembly block 405, and the assembly block 405 is fixedly connected to the assembly frame 406. The assembly frame 406 is equipped with a filter screen 407, a moving block 408, and a storage slot 409. The assembly frame 406 is equipped with a pull rod 410. The liquid storage tank 14 is hinged to the tank door 15. The assembly plate 404 is equipped with multiple sets of assembly blocks 405, and the assembly frame 406 is L-shaped. After prolonged use, coolant will produce sediment. In this case, the lead screw 402 above the reservoir 14 can be rotated, causing the lead screw to rotate and simultaneously drive the upper slider 403 to slide inside the assembly slot 401. The slider drives the assembly plate 404 to move, which in turn moves the lower assembly frame 406 inside the reservoir 14. The trapezoidal moving block 408 in front of the assembly frame, in conjunction with the filter screen 407, scoops the sediment to one side, collecting it in the storage slot 409 inside the moving block. After moving to one side of the reservoir 14, the upper cabinet door 8 can be opened via the hinge shaft, and the pull rod 410 above the assembly frame can be pulled, causing the assembly frame and assembly block 405 to slide out inside the assembly plate 404. This allows for the cleaning of the scooped-out sediment. If the cabinet 1 has been used for an extended period, dust may accumulate on the exposed cooling pipes 13. Since electronic components are installed inside the cabinet, the side panels 2 on both sides of the cabinet 1 can be removed. Pull the handle to remove the side panels to facilitate cleaning the dust accumulated above the cooling pipe 13. A liquid pump 12 is installed inside the liquid storage tank 14. The liquid pump 12 is connected to the upper end of the cooling pipe 13 on the left side inside the cabinet 1. A shell 11 is installed on the cabinet 1. A heat exchange assembly 6 is installed inside the shell 11. The shell 11 and the liquid storage tank 14 are connected by a return water pipe 7. The heat exchange assembly 6 includes an air inlet pipe 601, an air outlet pipe 602, a heat exchange tube 603, a filter cover 604, and a fan 605. The heat exchange tube 603 is installed inside the shell 11. 3. One end of the heat exchange tube 603 is connected to the upper end of the cooling tube 13 on the right side inside the cabinet 1, and the other end of the heat exchange tube 603 is connected to the return water pipe 7. The shell 11 is provided with an air inlet pipe 601 and an air outlet pipe 602. A fan 605 for drawing in external air is provided in the air inlet pipe 601. The front ends of the air inlet pipe 601 and the air outlet pipe 602 are threadedly connected to the filter cover 604. The cooling tube 13 is an S-shaped pipe, and the heat exchange tube 603 is a U-shaped pipe. In operation, the coolant inside the storage tank 14 is pumped by the pump 12 into the cooling pipe 13 on the left side of the cabinet 1, where it flows. The connecting pipe 5 below fills both cooling pipes with coolant. As the coolant flows through the cooling pipes, it absorbs the heat generated inside the cabinet. The coolant then enters the U-shaped heat exchange pipe 603 inside the shell 11. Simultaneously, the fan 605 inside the air inlet pipe 601 above the shell draws in outside air. The air generated by the fan dissipates heat from the coolant flowing inside the heat exchange pipes. The air is then exhausted through the exhaust pipe 602 on one side. Filter covers 604 on the air inlet and exhaust pipes prevent dust from entering. The coolant, after being cooled by the heat exchange pipes, returns to the storage tank 14 through the return pipe 7, and is then pumped out again by the pump 12, continuously circulating the coolant to absorb heat generated inside the cabinet, thus completing the heat dissipation process.

[0015] Working principle: When using the heat dissipation type high-voltage switchgear, the coolant inside the storage tank 14 is pumped into the cooling pipe 13 on the left side of the cabinet 1 by the pump 12. The coolant flows through the connecting pipe 5 below, filling the cooling pipes on both sides with coolant. The coolant absorbs the heat generated inside the cabinet as it flows through the cooling pipes. The coolant then enters the U-shaped heat exchange pipe 603 inside the shell 11. At the same time, the fan 605 inside the air inlet pipe 601 above the shell draws in outside air. The air generated by the fan dissipates the heat absorbed by the coolant flowing inside the heat exchange pipe. The air is then discharged through the air outlet pipe 602 on one side. The filter cover 604 on the air inlet and outlet pipes prevents dust from entering. After the coolant is cooled by the heat exchange tubes, it returns to the storage tank 14 through the return water pipe 7 and is drawn back by the pump 12, so that the coolant is continuously circulated to absorb the heat generated inside the cabinet and complete the heat dissipation inside the cabinet. After long-term use, the coolant will produce sediment. At this time, the lead screw 402 above the storage tank 14 can be rotated to rotate the lead screw. At the same time, the lead screw drives the upper slider 403 to slide inside the assembly slot 401. The slider drives the assembly plate 404 to move. At this time, the assembly plate drives the lower assembly frame 406 to move inside the storage tank 14. The trapezoidal moving block 408 in front of the assembly frame, together with the filter screen 407, scoops the sediment inside to one side and collects it into the storage slot 409 inside the moving block. After moving to the side of the liquid storage tank 14, open the upper cabinet door 8 via the hinge shaft, and pull the pull rod 410 above the assembly frame. This allows the assembly frame and assembly block 405 to slide out inside the assembly plate 404, enabling the removal of shoveled sediment. If the cabinet 1 has been used for an extended period, dust may accumulate on the exposed cooling pipes 13. Since electronic components are installed inside the cabinet, the side panels 2 on both sides of the cabinet 1 can be removed by pulling the handles. This facilitates cleaning of the dust accumulated above the cooling pipes 13, thus completing a series of tasks. Content not described in detail in this specification is prior art known to those skilled in the art.

[0016] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
