Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and more particularly to a transformer for an offshore platform submersible electric pump. Background Art

[0002] Transformers are categorized as dry-type and wet-type. Wet-type transformers are electrical devices that use the principle of electromagnetic induction, using oil as a cooling medium, to achieve voltage conversion. The operating principle of a wet transformer is that when a high voltage passes through one winding of the transformer, a corresponding low voltage is induced in the other winding (or vice versa, a low voltage is converted to a high voltage). This is because the current in the winding generates a magnetic field, and the changing magnetic field induces a voltage in the other winding. Simultaneously, the current passing through the winding generates heat, and the oil in the tank dissipates the heat, preventing the winding from overheating.

[0003] However, there are some shortcomings in the use of existing wet transformers, as follows:

[0004] When the existing wet-type transformer is in operation, a circulating oil tank and a fan and a heat sink are installed on the outside of the transformer. The heat absorbed by the cooling oil inside the transformer is dissipated through the fan and the heat sink, thereby achieving the purpose of cooling the transformer temperature. When the temperature is too high, the cooling oil in the oil tank and the cooling oil in the transformer are replaced to achieve the purpose of controlling the transformer temperature. However, when the existing transformer is in operation, it is difficult to adjust the temperature control of the fan and the oil tank in real time according to the temperature change. It is impossible to adjust the cooling power according to the working intensity of the transformer, so it is not convenient to save the cooling cost during the operation of the transformer.

[0014] Technical effects and advantages of the present invention:

[0015] In the present invention, during the operation of the transformer, the temperature of the winding increases, causing the temperature of the cooling oil inside the transformer casing to gradually increase. As the cooling oil temperature gradually increases, the volume of the cooling oil expands. Since the inside of the transformer casing is sealed, the expansion of the cooling oil pushes the first sliding block and the inductor slider to slide inside the first square tube and the inductor slide rail. During the sliding of the first sliding block and the inductor slider, the oil pipes are moved one by one to the right side of the first sliding block and the inductor slider, and the power of the oil pump assembly increases as the inductor slider approaches leftward on the inside of the inductor slide rail. As the temperature inside the transformer gradually increases, the oil pipes are gradually located to the right side of the second sliding block and the first sliding block, and the circulation speed of the hydraulic oil inside the first guide pipe is accelerated, thereby accelerating the replacement speed between the cooling oil with a higher temperature inside the transformer and the hydraulic oil with a lower temperature inside the oil tank body, thereby effectively controlling the temperature of the hydraulic oil inside the transformer assembly and ensuring that the operating temperature of the transformer is maintained within a safe range.

[0016] During the use of the transformer of the present invention, the temperature inductor component, the heat dissipation component and the inner side of the second square tube are filled with cooling oil, while there is air in the buffer tube and the air pressure component. The cooling oil expands inside the transformer casing, causing the first sliding block and the inductor slider to move to the left, so that part of the hydraulic oil on the left side of the first sliding block will enter the buffer tube. The first sliding block moves to the left, exposing the oil pipe. Under the action of gravity, the liquid level inside the buffer tube drops to its original position, and part of the cooling oil on the left side of the first sliding block and the second sliding block enters the transformer casing. Since the inductor slider moves to the left, the power of the oil pump component increases, so that the liquid entering the second square tube per unit time increases, thereby causing the second sliding block to move to the left, and then the liquid level of the buffer tube increases, and then drops to its original position during the process of the first sliding block moving again. As the temperature inside the transformer casing rises, the number of oil pipes joining the circulating oil circuit increases, so that the equipment can adjust the working efficiency of the cooling oil circuit according to temperature changes, which is convenient for the equipment to perform autonomous adjustment.

[0017] In the process of gradually decreasing the working temperature of the equipment, the present invention will gradually reduce the volume of the cooling oil inside the equipment, thereby causing the first sliding block to move to the right. When the first sliding block moves to the right by the distance of an oil pipe, the pneumatic component works to inject air into the inside of the buffer circular tube. Under the action of the atmospheric pressure inside the second square tube, the second sliding block moves to the right by the distance of an oil pipe, and then the pneumatic component works to discharge the injected air, and then repeats the above work until the second sliding block and the first sliding block return to their original positions, so that the equipment can reset itself, and the air injected by the pneumatic component will be blocked by the third block, avoiding the gas from directly entering the oil circuit circulation, thereby ensuring the normal use of the equipment.

[0018] In the present invention, when the inductor slider is located in the right half, only the fan assembly on the right side works to inject gas into the air guide housing through the air outlet, and takes away the temperature of the oil pipe through the outside of the oil pipe, so that the cooling oil can be effectively cooled when passing through the oil pipe, and then injected into the oil tank body, so that the equipment can continue to work for a long time, which is convenient for stabilizing the temperature of the equipment during operation.

[0019] When the cooling oil enters the oil tank body, the spiral plate moves as it guides, and the cooling oil delivered by the second guide pipe is the cooling oil located at the innermost side of the oil tank body, which can effectively isolate the temperature of the cooling oil. When the transformer works at high intensity for a long time, the temperature rise rate of the cooling oil can be effectively reduced. When the second sliding block moves to the left, the guide telescopic pipe will gradually extend, ensuring the normal use of the oil circuit control component. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples.

The movement of the first sliding block 205 to the left exposes the oil pipe 302. Under the action of gravity, the liquid level inside the buffer circular tube 403 will drop to its original position, and the cooling oil on the left side of the first sliding block 205 and the second sliding block 406 will partially enter the transformer housing 101. Since the inductor slider 206 moves to the left, the power of the oil pump assembly 506 increases, so that the liquid entering the second square tube 401 per unit time increases, thereby causing the second sliding block 406 to move to the left, and then causing the liquid level of the buffer circular tube 403 to rise, and then drop to its original position during the process of the first sliding block 205 moving again. As the temperature inside the transformer housing 101 increases, the number of oil pipes 302 joining the circulating oil circuit increases, so that the equipment can adjust the working efficiency of the cooling oil circuit according to temperature changes, which facilitates the equipment to perform autonomous adjustment.

Since the inner side of the transformer casing 101 is in a sealed state, the cooling oil will push the first sliding block 205 to And the inductor slider 206 slides on the inner side of the first square tube 201 and the inductor slide rail 202. During the sliding of the first sliding block 205 and the inductor slider 206, the oil circuit tube 302 will move one by one to the right side of the first sliding block 205 and the inductor slider 206, and the power of the oil pump assembly 506 will increase as the inductor slider 206 approaches the left side of the inner side of the inductor slide rail 202. As the temperature inside the transformer gradually increases, the oil circuit tube 302 will gradually be located to the right side of the second sliding block 406 and the first sliding block 205, and the circulation speed of the hydraulic oil inside the first guide tube 407 will become faster, so that the replacement speed between the cooling oil with higher temperature inside the transformer and the hydraulic oil with lower temperature inside the oil tank body 502 will be faster, thereby effectively controlling the temperature of the hydraulic oil inside the transformer assembly 1 and ensuring that the operating temperature of the transformer is maintained within a safe range.

When the first sliding block 205 moves to the right by the distance of an oil pipe 302, the pneumatic component 404 works to inject air into the inside of the buffer circular tube 403, and under the action of the atmospheric pressure inside the second square tube 401, the second sliding block 406 moves to the right by the distance of an oil pipe 302, and then the pneumatic component 404 works to discharge the injected air, and then repeats the above work until the second sliding block 406 and the first sliding block 205 return to their original positions, so that the equipment can reset itself, and the air injected in the pneumatic component 404 will be blocked by the third block 4014, avoiding the gas directly entering the oil circuit circulation, thereby ensuring the normal use of the equipment.

[0035] In a preferred embodiment, the oil tank assembly 5 includes a fixed plate 501, the top of which is fixedly connected to an oil tank body 502, an inner side of which is fixedly connected to a spiral plate 503, the front and back sides of the oil tank body 502 are fixedly connected to a second guide pipe 504, the front and back sides of the bottom of the fixed plate 501 are fixedly connected to a third guide pipe 505, the other side of the third guide pipe 505 is fixedly connected to an oil pump assembly 506, and the top of the oil pump assembly 506 is fixedly connected to a fourth guide pipe 507; when the cooling oil enters the interior of the oil tank body 502, it moves along with the guidance of the spiral plate 503, and the cooling oil delivered by the second guide pipe 504 is the cooling oil located at the innermost side of the oil tank body 502, which can effectively isolate the temperature of the cooling oil and effectively reduce the temperature rise rate of the cooling oil when the transformer works at high intensity for a long time. When the second sliding block 406 moves to the left, the guide telescopic pipe 408 is gradually extended to ensure the normal use of the oil circuit control assembly 4.

[0036] In a preferred embodiment, the height of the positioning groove 104 is clearance-matched with the height of the first square tube 201, the side of the first square tube 201 on which the conductive notch 207 is opened is on the same plane as the inner side of the positioning groove 104, the cross-sectional dimensions inside the first square tube 201 are clearance-matched with the cross-sectional dimensions of the first sliding block 205, the width of the inner side of the inductor slide rail 202 is clearance-matched with the width of the inductor slider 206, and the distance between the top of the inner side of the first square tube 201 and the top of the inductor slide rail 202 is clearance-matched with the height of the inductor slider 206.

[0037] In a preferred embodiment, the diameter of the oil circuit tube 302 is clearance-matched with the diameter of the first oil circuit positioning circular hole 203, the diameter of the oil circuit tube 302 is clearance-matched with the diameter of the second oil circuit positioning circular hole 402, the center line of the square groove 305 overlaps with the center line of the oil circuit tube 302 in the positive projection, the center of the arc-shaped notch 304 coincides with the center of the oil circuit tube 302, and the size of the air inlet groove 303 is clearance-matched with the size of the air outlet 107.

[0038] In a preferred embodiment, the outer dimensions of the cross-section of the second sliding block 406 are clearance-matched with the cross-sectional dimensions of the extraction groove 4011 and the sliding notch 4012, the cross-sectional dimensions of the rotation positioning groove 4013 are clearance-matched with the cross-sectional dimensions of the rotation belt 405 and the rotation limiting belt 409, the length of the spiral plate 503 is the same as the length of the inner side of the oil tank body 502, and the connection position of the second guide tube 504 and the oil tank body 502 is located on the inner side of the spiral plate 503.

[0039] The working principle of the present invention is as follows: during the operation of the transformer, the temperature of the winding 103 rises due to its operation, causing the temperature of the cooling oil inside the transformer housing 101 to gradually rise. During the gradual increase in the temperature of the cooling oil, the volume of the cooling oil will expand. Since the inside of the transformer housing 101 is sealed, the expansion of the cooling oil will push the first sliding block 205 and the inductor slider 206 to slide inside the first square tube 201 and the inductor slide rail 202. During the sliding process of the first sliding block 205 and the inductor slider 206, the oil pipe 302 will be moved one by one to the first sliding block 205 and the inductor slider 206. 6, and the power of the oil pump assembly 506 increases as the inductor slider 206 approaches the left side of the inductor slide rail 202, so that when the temperature inside the transformer gradually increases, the oil pipe 302 will gradually be located on the right side of the second sliding block 406 and the first sliding block 205, and the circulation speed of the hydraulic oil in the first guide pipe 407 will be accelerated, so that the replacement speed between the cooling oil with a higher temperature inside the transformer and the hydraulic oil with a lower temperature inside the oil tank body 502 will be accelerated, thereby effectively controlling the temperature of the hydraulic oil inside the transformer assembly 1 and ensuring that the operating temperature of the transformer is maintained within a safe range;

[0040] When the transformer is in use, the temperature inductor component 2, the heat dissipation component 3 and the inside of the second square tube 401 are filled with cooling oil, and there is air in the buffer tube 403 and the air pressure component 404. The cooling oil inside the transformer housing 101 expands, causing the first sliding block 205 and the inductor slider 206 to move to the left, so that part of the hydraulic oil on the left side of the first sliding block 205 will enter the buffer tube 403. When the first sliding block 205 moves to the left, the oil pipe 302 is exposed. Under the action of gravity, the liquid level inside the buffer tube 403 drops to its original position, and the oil pipe 302 is exposed. The cooling oil on the left side of the sliding block 406 partially enters the transformer housing 101, and the power of the oil pump assembly 506 increases due to the leftward movement of the inductor slider 206, which increases the amount of liquid entering the second square tube 401 per unit time. This causes the second sliding block 406 to move to the left, which in turn causes the liquid level of the buffer circular tube 403 to rise, and then drops to its original position during the next movement of the first sliding block 205. As the temperature inside the transformer housing 101 rises, the number of oil pipes 302 added to the circulating oil circuit increases, allowing the equipment to adjust the working efficiency of the cooling oil circuit according to temperature changes, facilitating autonomous regulation of the equipment.

[0041] As the operating temperature of the equipment gradually decreases, the volume of the cooling oil inside the equipment will gradually decrease, causing the first sliding block 205 to move to the right. When the first sliding block 205 moves to the right by the distance of the oil pipe 302, the air pressure component 404 works to inject air into the buffer circular tube 403. Under the action of the atmospheric pressure inside the second square tube 401, the second sliding block 406 moves to the right by the distance of the oil pipe 302, and then the air pressure component 404 works to discharge the injected air, and then repeats the above work until the second sliding block 406 and the first sliding block 205 return to their original positions, so that the equipment can reset itself, and the air injected by the air pressure component 404 will be blocked by the third stopper 4014, preventing the gas from directly entering the oil circuit circulation, thereby ensuring the normal use of the equipment.

[0042] When the inductor slider 206 is located in the right half, only the right fan assembly 106 is in operation, injecting gas into the air guide housing 301 through the air outlet 107. The gas then passes through the outside of the oil pipe 302, removing the temperature of the oil pipe 302. This effectively cools the cooling oil as it passes through the oil pipe 302, and the oil is then injected into the oil tank body 502. This allows the device to operate continuously for a long time, facilitating stable operating temperature of the device.

[0043] When the cooling oil enters the oil tank body 502, it moves with the guidance of the spiral plate 503, and the cooling oil delivered by the second guide pipe 504 is the cooling oil located at the innermost side of the oil tank body 502, which can effectively isolate the temperature of the cooling oil. When the transformer works at high intensity for a long time, it can effectively reduce the temperature rise rate of the cooling oil. When the second sliding block 406 moves to the left, the guide telescopic pipe 408 will gradually extend to ensure the normal use of the oil circuit control component 4.
