Description

A transformer with a liquid cooling structure Technical Field

[0001] This invention relates to the field of transformer technology, and in particular to a transformer with a liquid cooling structure. Background Technology

[0002] As a key piece of equipment in the power system, transformers bear the heavy responsibility of voltage transformation and power transmission and distribution. Their operational stability is crucial to the safety and reliability of the entire system. Among them, autotransformers have the advantages of small size, low material consumption, and high efficiency because the primary and secondary windings are on the same winding. However, during operation, the windings and other components will generate a lot of heat due to the current. If heat cannot be dissipated in time, it will accelerate the aging of insulation and cause failures that damage the transformer.

[0003] Traditional transformers mostly use oil cooling for heat dissipation, but the cooling oil is prone to loss and reduction during long-term circulation. Currently, most transformers lack automatic oil replenishment functions, making it difficult to replenish the cooling oil in a timely manner; at the same time, air bubbles are prone to accumulate in the cooling oil during continuous circulation, but existing equipment structures are not equipped with effective automatic venting mechanisms, resulting in gas retention that affects heat dissipation efficiency and poses a hidden danger to the stable operation of the equipment.

Beneficial Effects

[0015] 1. In this invention, when the cooling oil level inside the auxiliary oil tank drops, the float plate follows the drop in cooling oil level. At the same time, the float plate and the linkage sealing block move downward, causing the refueling pipe to open automatically. Simultaneously, it works with the oil storage tank and the one-way air intake valve to achieve precise oil replenishment. The hexagonal sliding rod design effectively prevents rotational deviation, and the conical structure at the top of the float plate prevents cooling oil from accumulating above the float plate, which helps to ensure the floating effect of the float plate. This ensures that the cooling oil is always maintained at the optimal level, avoiding the risk of heat dissipation failure due to insufficient oil.

[0016] 2. This invention, by positioning the cooling oil level at halfway point of the auxiliary oil tank, allows air bubbles inside the cooling oil to be automatically discharged into the auxiliary oil tank when the cooling oil circulates into it; simultaneously, when there is excessive gas inside the auxiliary oil tank, the air pressure will push open the exhaust block for automatic exhaust; thus, the air bubbles can be effectively and automatically discharged during the cooling oil circulation process, preventing gas stagnation from affecting heat dissipation efficiency.

[0017] 3. This invention, by providing an adjusting screw, a threaded bracket, and a fixing rod, can adjust the up and down position of the pressure frame, thereby changing the initial compression of the spring between the pressure frame and the exhaust block; thus, it can adjust the exhaust threshold; thereby meeting the precise exhaust control requirements under different working conditions.

[0018] 4. This invention, by providing a dustproof cylinder and dustproof frame and its internal filter, can prevent dust from entering the fixed box, which helps to prevent the cooling pipe surface from being reduced in heat dissipation due to dust adsorption; at the same time, by rotating the shaft, the scraper can rotate with the fan blades, thereby enabling the scraper to remove dust from the surface of the filter inside the dustproof cylinder, ensuring that the air intake channel remains unobstructed for a long time, thereby maintaining stable heat dissipation performance and air circulation efficiency.

[0019] 5. In this invention, when the fan starts running, the thrust generated by the wind will automatically push the sealing plate open, causing an air convection channel to be formed inside the fixed box, which will significantly accelerate the heat dissipation rate of the cooling pipe surface and improve the heat dissipation efficiency. When the fan stops working, the sealing plate will automatically return to its original position under the synergistic action of the reset rod and the spring, and will fit tightly against the dustproof frame, completely covering the filter screen, effectively preventing dust from adhering to the surface of the filter screen inside the dustproof frame, and ensuring the long-term stable operation of the equipment.

[0020] 6. This invention, by setting up an array of heat-absorbing tubes and heat-absorbing sheets that work together with them, can construct a highly efficient heat conduction structure, enabling the heat-absorbing tubes to fully absorb the heat generated during winding operation; this is beneficial for heat dissipation of the windings and ensures stable operation of the transformer.

[0040] Example 2: Please refer to Figures 5 to 8: Based on Example 1, the cooling structure 3 includes: a load-bearing frame 301, a fixed box 302, an oil collecting pipe 303, a cooling pipe 304, a fan 305, a dustproof frame 306, a sealing ring 307, a reset rod 308, a sealing plate 309, and a sealing groove A3010; the load-bearing frame 301 is fixedly installed on the outside of the housing 101 and the base 1 respectively; the fixed box 302 is fixedly installed on the outside of the load-bearing frame 301; the oil collecting pipe 303 is fixedly installed inside the fixed box 302, and the oil collecting pipe 303 is configured as two sets, and one set of oil collecting pipe 303 is fixedly connected to the upper fixed pipe 201. Fixed connection; cooling pipe 304 is fixedly installed between the two sets of oil collection pipes 303, and the cooling pipes 304 are arranged in an array; fan 305 is fixedly installed inside one side of fixed box 302; dustproof frame 306 is fixedly installed inside both sides of fixed box 302, and a filter screen is installed inside dustproof frame 306; sealing ring 307 is fixedly installed on the outside of dustproof frame 306; reset rod 308 is slidably installed inside dustproof frame 306, and a spring is provided between the end of reset rod 308 and the outside of dustproof frame 306; sealing plate 309 is fixedly installed at the end of reset rod 308, and the outside of sealing plate 309 is connected to dustproof frame 306.

[0041] Example 3: Please refer to Figures 10, 13, and 14: Based on Examples 1 and 2, the exhaust assembly 6 includes: an exhaust pipe 601, a fixing rod 602, a threaded bracket 603, an adjusting screw 604, a pressure applying bracket 605, an exhaust block 606, and a sealing ring 607; the exhaust pipe 601 is fixedly installed inside the top side of the auxiliary oil tank 501; the fixing rod 602 is fixedly installed at the top of the exhaust pipe 601; the threaded bracket 603 is fixedly installed at the top of the fixing rod 602; the adjusting screw 604 is threadedly connected inside the threaded bracket 603, and a knob is fixedly installed at the top of the adjusting screw 604; the pressure applying bracket 605 is rotatably installed at the bottom end of the adjusting screw 604, and the pressure applying bracket 605 can slide. The exhaust block 606 is slidably disposed on the outside of the fixed rod 602, and the bottom of the exhaust block 606 is in contact with the top of the exhaust cylinder 601; a spring is disposed between the top of the exhaust block 606 and the pressure frame 605, and the spring is located on the outside of the fixed rod 602; a sealing ring 607 is fixedly disposed on the bottom of the exhaust block 606, and the sealing ring 607 is movably disposed inside the top side of the exhaust cylinder 601; its specific function is: by providing an adjusting screw 604, a threaded bracket 603 and a fixed rod 602, the up and down position of the pressure frame 605 can be adjusted, thereby changing the initial compression of the spring between the pressure frame 605 and the exhaust block 606; thereby adjusting the exhaust threshold.

[0042] The specific usage and function of this embodiment are as follows: In this invention, the transformer base 1 is securely installed in a suitable position, ensuring that the installation surface is flat and firm to guarantee the stability of the transformer during operation; then, the external power supply line is accurately connected to the terminals A106 and B107, the transformer starts working, and the winding 105 generates heat; rotating the knob at the top of the adjusting screw 604 causes the adjusting screw 604 to move up and down inside the threaded bracket 603, thereby driving the pressure bracket 605 to slide up and down outside the fixed rod 602, changing the initial compression of the spring between the pressure bracket 605 and the exhaust block 606, thereby achieving precise adjustment of the exhaust threshold to meet the exhaust control requirements under different working conditions; the oil pump 503 is then started. Oil pump 503 pumps cooling oil into cooling pipe 304 via oil outlet pipe 502, auxiliary oil pipe 504, and a set of oil collecting pipes 303. After circulating in cooling pipe 304, the cooling oil is smoothly delivered to annular pipe A202 via another set of oil collecting pipes 303 and upper fixed pipe 201. The cooling oil entering annular pipe A202 continues to flow, flowing into annular pipe B204 via heat absorption pipe 205. Finally, the cooling oil in annular pipe B204 flows back to auxiliary oil tank 501 via lower fixed pipe 203, thus completing a complete cycle. Heat absorption pipe 205 fully absorbs the heat generated by winding 105 during operation through cooling oil and heat absorption fins 206, effectively dissipating heat from winding 105 and ensuring stable transformer operation. The heat generated by the winding 105 is carried into the cooling pipe 304; the fan 305 is started, generating airflow, and the thrust generated by the airflow automatically pushes open the sealing plate 309, causing an air convection channel to form inside the fixed box 302, accelerating the heat dissipation rate of the surface of the cooling pipe 304 and improving heat dissipation efficiency; the cooled oil flows back to the heat absorption pipe 205 to continue absorbing heat from the winding 105, and so on, to achieve continuous cooling of the transformer; when the cooling oil level drops due to circulation consumption, the float plate 5011 drops with the cooling oil level. Since the sliding rod 5010 is set as a hexagon, it can effectively prevent rotational deviation and ensure that the float plate 5011 descends stably; the float plate 5011 moves downward in conjunction with the sealing block 5012, causing the sealing protrusion 50 13. Upon disengaging from the sealing groove B506, the refueling pipe 505 automatically opens, simultaneously cooperating with the oil reservoir 507 and the one-way air intake valve 508 to achieve precise oil replenishment, ensuring that the cooling oil always maintains the optimal oil level and avoiding the risk of heat dissipation failure due to insufficient oil. When the cooling oil circulates into the auxiliary oil tank 501, the air bubbles inside the cooling oil are automatically discharged into the auxiliary oil tank 501. When there is too much gas inside the auxiliary oil tank 501 and the gas pressure reaches the exhaust threshold, the gas pressure will push open the exhaust block 606, and the sealing ring 607 will disengage from the top side of the exhaust pipe 601 to achieve automatic exhaust and prevent gas retention from affecting heat dissipation efficiency. After exhaust is completed, the exhaust block 606 is reset under the action of the spring, resealing the exhaust pipe 601 and ensuring the airtightness of the auxiliary oil tank 501.The dust cover 401, dust cover frame 306, and their internal filter screen prevent dust from entering the fixed box 302, avoiding a decrease in heat dissipation due to dust adhering to the surface of the cooling pipe 304. Simultaneously, the rotating shaft 403 is fixedly connected to the rotating shaft inside the fan 305. When the fan 305 operates, the rotating shaft 403 drives the scraper 404 to rotate with the fan blades, scraping away dust from the surface of the filter screen inside the dust cover 401, ensuring the air intake channel remains unobstructed and maintaining stable heat dissipation performance and airflow efficiency. When the fan 305 stops working, the sealing plate 309 automatically returns to its original position under the coordinated action of the reset rod 308 and the spring, tightly fitting against the dust cover frame 306, completely covering its internal filter screen and effectively preventing dust adhesion to the surface of the filter screen inside the dust cover frame 306.
