Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and more particularly to a moisture-proof and heat-dissipating transformer cabinet. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil and the iron core (magnetic core). In electrical equipment and wireless circuits, it is often used to increase or decrease voltage, match impedance, and provide safety isolation. In a generator, whether the coil moves through the magnetic field or the magnetic field moves through a fixed coil, an electric potential can be induced in the coil.

[0003] A Chinese patent with application number CN202211101470.8 discloses a heat dissipation cabinet for a transformer, specifically comprising: a chassis, the left and right sides of the outer surface of the chassis are rotatably connected with a cabinet door, two cabinet doors are provided, a fixed groove is opened on the top of the chassis, a slide rail is fixedly connected to the inner surface of the fixed groove, and an anti-skid mechanism is rotatably connected to the outer surface of the slide rail; an anti-skid mechanism, a steering mechanism, a fixing mechanism and other structures are provided inside the equipment, and a steering structure is provided inside the equipment, which increases the flexibility of the equipment. When the equipment needs to be inspected and dissipated, it is only necessary to rotate the driving structure provided on the inside to rotate the direction of the equipment. In addition, an extended protection structure is added to the oil outlet and electrical connection of the equipment, which increases the stability when the pipeline is connected to the equipment. When the pipeline is pulled by external force, the damage caused by the pulling to the pipeline and the equipment can be reduced, and the sealing of the pipeline is also better.

[0004] Long-term operation of the transformer in humid places and rainy areas will cause the transformer to get damp, which will cause the insulation resistance of the transformer winding to decrease and be broken down. In severe cases, the transformer will be burned and cause an electrical fire. In the prior art, the transformer is sealed under atmospheric pressure by sealing to form a relatively low pressure environment inside the transformer, which can effectively prevent external moisture from entering the transformer. However, after the transformer is sealed, the heat dissipation of the transformer will be seriously affected. Overheating will cause the internal materials of the transformer to age faster, shorten its overall service life, cause economic losses, increase the risk of failure, and even cause fire and explosion of the transformer.

[0017] Technical effects and advantages of the present invention:

[0018] 1. The present invention provides a heat dissipation mechanism and a sealing mechanism. On the one hand, when the transformer cabinet does not need to dissipate heat, the transformer cabinet is sealed to prevent water vapor from entering the interior of the transformer cabinet when it rains, and to prevent the transformer from getting damp, causing the insulation resistance of the transformer winding to decrease and be broken down. In severe cases, the transformer may be burned to cause electrical fires and other problems, thereby protecting the components inside the transformer cabinet. On the other hand, when the transformer cabinet needs to dissipate heat, the transformer cabinet can be unsealed, and the wind generated by the rotation of the blades can be used to discharge the hot air, thereby dissipating the heat of the transformer, avoiding overheating that causes accelerated aging of the internal materials of the transformer, shortening its overall service life, and avoiding overheating that burns the transformer to cause electrical fires and explosions, resulting in economic losses and increased failure risks, thereby improving the stability and safety of the transformer operation.

[0019] 2. The present invention provides a dust removal mechanism so that the scraper can clean the dust on the filter plate by scraping and blowing, so that the dust on the filter plate can be cleaned more cleanly, and dust can be prevented from accumulating on the filter plate, causing the filter plate to be gradually blocked, resulting in a gradual decrease in the speed of gas passing through the filter plate, so that the blades cannot circulate and discharge the heat generated inside the transformer cabinet in time, resulting in excessive temperature inside the transformer cabinet to damage internal components, thereby reducing the risk of transformer failure and further improving the cooling effect of the transformer;

[0020] 3. The present invention provides a three-way hose. After a fire occurs inside the transformer cabinet, the three-way hose is burned off, and the injection of gas into the sealed chamber is stopped. The gas inside the sealed chamber is quickly discharged through the burnt portion of the three-way hose, so that the sealing plate can quickly seal the air inlet, air outlet and sealing port, restricting the outside air from entering the interior of the transformer cabinet, so that there is not enough oxygen inside the transformer cabinet for the flame to burn, thereby playing a role in extinguishing the fire and further protecting the transformer.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example 1

[0036] Refer to the instruction manual Figure 1-7 A moisture-proof heat-dissipating transformer cabinet according to an embodiment of the present invention comprises a transformer cabinet 1, a sealed door 2 is hingedly connected to the outer wall of the transformer cabinet 1, an air inlet 201 is provided on the outer wall of the sealed door 2, an air outlet 101 corresponding to the position of the air inlet 201 is provided on the outer wall of the transformer cabinet 1 on the side opposite to the sealed door 2, a heat dissipation mechanism 3 is arranged inside the transformer cabinet 1, and sealing mechanisms 4 are arranged on the inner walls of the transformer cabinet 1 and the sealed door 2, the two sealing mechanisms 4 correspond to the positions of the air outlet 101 and the air inlet 201 respectively, and dust removal mechanisms 5 are arranged on the two sealing mechanisms 4;

[0037] refer to Figure 2-4The heat dissipation mechanism 3 includes an exhaust pipe 301, which is fixedly connected to the inner wall of the transformer cabinet 1. A motor 302 is fixedly connected to the inner wall of the exhaust pipe 301. A temperature sensor 303 is fixedly connected to one side of the motor 302. A blade 304 is fixedly connected to the output shaft end of the motor 302. A cam 305 is fixedly connected to the outer wall of the output shaft of the motor 302. A piston 306 is sleeved on the outer wall of the cam 305. The piston 306 is slidably connected to the exhaust pipe 301. A valve 307 is slidably connected to the top of the piston 306. Through the setting of the valve 307, when the piston 306 discharges the gas inside the piston tube 308 into the three-way hose 310 through the one-way valve 309, the valve 307 seals the piston 306. When the piston 306 is discharged from the piston tube 308, the valve 307 seals the piston 306. When a part of the interior is detached, the valve 307 can inject gas into the piston tube 308, and the outer wall of the piston member 306 is plugged with the piston tube 308, and the piston tube 308 is fixedly connected to the inside of the transformer cabinet 1. The outer wall of the piston tube 308 is fixedly connected with a one-way valve 309, and the one end of the one-way valve 309 away from the piston tube 308 is fixedly connected with a three-way hose 310, and the other two ends of the three-way hose 310 are respectively fixedly connected to the two sealing mechanisms 4. Through the setting of the three-way hose 310, the three-way hose 310 can finally connect the two sealed chambers 402, so that the two sealed chambers 402 can be inflated to push the hollow sliding rod 403 to drive the pressure valve 404 and the blocking plate 405 to move downward, so that the air inlet 201, the air outlet 101 and the blocking port 407 are all opened for heat dissipation.

[0038] refer to Figure 5-9 The sealing mechanism 4 includes a mounting frame 401, and the two mounting frames 401 are fixedly connected to the inner walls of the transformer cabinet 1 and the sealing door 2 respectively. A sealed chamber 402 is opened inside the mounting frame 401, and the sealed chamber 402 is communicated with the piston tube 308 through a three-way hose 310. A hollow slide rod 403 is sealingly and slidably connected in the sealed chamber 402, and a pressure valve 404 is fixedly connected to the bottom of the hollow slide rod 403. A blocking plate 405 is fixedly connected to the outer wall of the pressure valve 404. The blocking plate 405 is slidably connected to the inside of the mounting frame 401, and a cover plate 406 is fixedly connected to the inner side of the mounting frame 401. A blocking port 407 is opened on the cover plate 406. A plurality of first springs 408 are connected to the bottom of the blocking plate 405, and the other ends of the plurality of first springs 408 are all connected to the bottom of the mounting frame 401. The blocking plate 405 is located between the filter plate 509 and the cover plate 406, and the exhaust pipe 301 corresponds to the position of the air outlet 101.

[0039] In specific operation, when the temperature inside the transformer cabinet 1 is too high, the temperature sensor 303 detects that the temperature reaches the threshold value, and the motor 302 starts to work. The rotation of the motor 302 drives the blade 304 and the cam 305 to rotate. The rotation of the cam 305 drives the piston 306 to reciprocate up and down, so that the piston 306 continuously injects gas into the piston tube 308 through the valve 307, and then the gas in the piston tube 308 is injected into the three-way hose 310 through the one-way valve 309. The tube 310 injects gas into the interior of the two sealed chambers 402 respectively, so that the hollow slide rod 403 in the sealed chamber 402 drives the pressure valve 404 and the sealing plate 405 to move downward in the mounting frame 401 and squeeze the first spring 408, thereby causing the sealing plate 405 to stop sealing the air inlet 201, the air outlet 101 and the sealing port 407, so that when the air inside the transformer cabinet 1 can circulate, the wind generated by the rotation of the blades 304 can discharge the hot air, thereby dissipating the heat of the transformer.

[0040] Example 2

[0041] During actual use, in addition to spontaneous combustion caused by problems with wires and transformer components, the transformer cabinet may also spontaneously combust because of excessive dust accumulated inside the transformer cabinet, which hinders the heat dissipation of the wires and components. As a result, the heat of the wires and components cannot be dissipated in time, ultimately causing the transformer cabinet to spontaneously combust. Therefore, this embodiment improves the device described in the above embodiment.

[0042] refer to Figure 9-12 The dust removal mechanism 5 includes a flow slot 501 opened at the bottom of the mounting frame 401, the top of the flow slot 501 is fixedly connected to a plug 502 matching the pressure valve 404, the plug 502 corresponds to the position of the pressure valve 404, the inside of the flow slot 501 is rotatably connected to a fan blade 503, the top of the fan blade 503 is fixedly connected to a reciprocating screw rod 504, the reciprocating screw rod 504 is rotatably connected to the inside of the flow slot 501, the top of the flow slot 501 is fixedly connected to a telescopic tube 505, the top of the telescopic tube 505 is fixedly connected to a slider 506, the slider 506 is sleeved on the outer wall of the reciprocating screw rod 504, and the slider 506 Engaged with the reciprocating screw rod 504, a slide groove 507 is provided on the side of the mounting frame 401 away from the sealed chamber 402, a slider 506 is slidably connected to the inside of the slide groove 507, a scraper 508 is fixedly connected to the outer wall of the slider 506, a filter plate 509 is fixedly connected to the inside of the mounting frame 401 between the slide groove 507 and the sealed chamber 402, a plurality of mutually interconnected air jets 510 are provided on the side of the scraper 508 close to the filter plate 509, and the plurality of air jets 510 are all connected to the telescopic tube 505, and dust exhaust grooves 6 are provided on the outer walls of the sealed door 2 and the transformer cabinet 1 below the air outlet 101 and the air inlet 201.

[0043] During specific operation, when the temperature inside the transformer cabinet 1 is too high, the hollow slide rod 403 in the sealed chamber 402 drives the pressure valve 404 and the sealing plate 405 to squeeze the first spring 408 and drop to the lowest position, and the pressure valve 404 will dock with the plug 502. At this time, the sealing plate 405 cannot continue to drop, and the gas pressure in the sealed chamber 402 and the hollow slide rod 403 will continue to increase. When the gas pressure in the sealed chamber 402 and the hollow slide rod 403 reaches the pressure threshold of the pressure valve 404, the gas in the sealed chamber 402 and the hollow slide rod 403 will enter the circulation groove 501 through the plug 502, and enter the interior of the telescopic tube 505 along the circulation groove 501. In this process, the gas will push the fan blades 503 to rotate, and the rotation of the fan blades 503 will drive the reciprocating screw 504 to rotate. The rotation of the reciprocating screw 504 will drive the slider 506 to reciprocate up and down, so that the slider 506 pulls the telescopic tube 505 to move together The scraper 508 is driven to scrape off the dust accumulated on the outside of the filter plate 509. At the same time, the gas in the telescopic tube 505 enters the interior of the scraper 508 through the slider 506, and blows the dust accumulated on the outside of the filter plate 509 through a plurality of mutually connected air jets 510. The dust cleaned off the filter plate 509 by the scraper 508 can be discharged through the dust discharge slot 6, so that the scraper 508 can clean the dust on the filter plate 509 by scraping and blowing, so that the dust on the filter plate 509 can be cleaned more cleanly, and dust can be prevented from accumulating on the filter plate 509, causing the filter plate 509 to be gradually blocked, resulting in the speed of gas passing through the filter plate 509 gradually decreasing, causing the blade 304 to be unable to circulate and discharge the heat generated inside the transformer cabinet 1 in time, resulting in the internal temperature of the transformer cabinet 1 being too high to damage the internal components, thereby reducing the risk of transformer failure and further improving the cooling effect of the transformer.

[0044] Example 3

[0045] In actual use, when the temperature inside the transformer cabinet 1 returns to normal, the motor 302 will stop working, causing the blades 304 and the cam 305 to stop operating, and further preventing gas from being injected into the sealed chamber 402. At the same time, the first spring 408 that is squeezed and contracted when the sealing plate 405 descends will stretch and reset. However, since there is still gas that cannot be completely discharged in the sealed chamber 402 and the hollow slide rod 403 at this time, the first spring 408 cannot push the sealing plate 405 to reset, making it impossible for the air inlet 201, the air outlet 101 and the sealing port 407 to be sealed. Moisture will enter the transformer cabinet 1 through the air inlet 201, the air outlet 101 and the sealing port 407, causing the transformer to become damp, resulting in a decrease in the insulation resistance of the transformer winding and breakdown. In severe cases, the transformer will be burned, causing electrical fires and explosions. Therefore, this embodiment improves the device described in the above embodiment.

[0046] refer to Figure 7-8 An air storage chamber 409 is provided inside the mounting frame 401 above the sealed chamber 402, a sealing plug 410 is sealingly and slidably connected inside the air storage chamber 409, a second spring 411 is connected between the bottom of the sealing plug 410 and the bottom of the air storage chamber 409, an exhaust hole 412 penetrating the air storage chamber 409 and connected to the sealed chamber 402 is provided on the side of the mounting frame 401 away from the slide groove 507, a heat expansion gas is arranged inside the air storage chamber 409 above the sealing plug 410, and the sealing plug 410 is located above the exhaust hole 412.

[0047] During specific operation, since heat-expanding gas is arranged above the sealing plug 410 inside the gas storage chamber 409, when the temperature inside the transformer cabinet 1 is too high, the heat-expanding gas between the gas storage chamber 409 and the sealing plug 410 will expand, and the expanded gas will push the sealing plug 410 to squeeze the second spring 411 to slide downward in the gas storage chamber 409 and block the exhaust hole 412. At this time, the sealed chamber 402 is in a sealed state. After the gas enters the sealed chamber 402 through the three-way hose 310, the gas can normally push the hollow slide rod 403 to drive the pressure valve 404 and the sealing plate 405 to move downward in the mounting frame 401, so that the sealing plate 405 stops sealing the air inlet 201, the air outlet 101 and the sealing port 407, so that the wind generated by the rotation of the blades 304 can discharge the hot air;

[0048] When the temperature inside the transformer cabinet 1 is normal, the thermally expanded gas between the gas storage chamber 409 and the sealing plug 410 will no longer expand. At this time, the second spring 411 squeezed by the sealing plug 410 will push the sealing plug 410 back to the initial position, and the exhaust hole 412 will be reopened. At this time, the first spring 408 will push the blocking plate 405 to reset, and the blocking plate 405 drives the hollow slide bar 403 to slide upward in the sealed chamber 402 through the pressure valve 404, so that the residual gas in the sealed chamber 402 and the hollow slide bar 403 can be gradually discharged through the exhaust hole 412. After the gas inside the sealed chamber 402 is discharged, the first spring 408 can push the blocking plate 405 to rise and re-seal the air inlet 201, the air outlet 101 and the blocking port 407, so as to achieve the effect of sealing the transformer cabinet 1 when the transformer cabinet 1 does not need to dissipate heat, so as to prevent water vapor from entering the interior of the transformer cabinet 1 when it rains, causing a bad influence on the components inside the transformer cabinet 1 and causing damage to the components.

[0049] It should be noted that after a fire occurs inside the transformer cabinet 1, the three-way hose 310 is burned off, and the injection of gas into the sealed chamber 402 will stop. The gas inside the sealed chamber 402 will be quickly discharged through the burnt portion of the three-way hose 310, allowing the sealing plate 405 to quickly seal the air inlet 201, the air outlet 101 and the sealing port 407, thereby limiting the outside air from entering the interior of the transformer cabinet 1, so that there is not enough oxygen inside the transformer cabinet 1 for the flame to burn, thereby playing a role in extinguishing the fire and further protecting the transformer.

[0050] To sum up, through the cooperation of the heat dissipation mechanism 3 and the sealing mechanism 4, on the one hand, when the transformer cabinet 1 does not need to dissipate heat, the transformer cabinet 1 is sealed to prevent water vapor from entering the interior of the transformer cabinet 1 when it rains, and to prevent the transformer from getting damp, causing the insulation resistance of the transformer winding to decrease and be broken down. In severe cases, the transformer may be burned to cause electrical fires and other problems, thereby protecting the components inside the transformer cabinet 1. On the other hand, when the transformer cabinet 1 needs to dissipate heat, the transformer cabinet 1 can be unsealed, and the wind generated by the rotation of the blades 304 can be used to discharge the hot air, thereby dissipating the heat of the transformer, avoiding overheating that causes accelerated aging of the internal materials of the transformer, shortening its overall service life, avoiding overheating that burns the transformer to cause electrical fires and explosions, causing economic losses, and increasing the risk of failure, thereby improving the stability and safety of the transformer operation.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
