Description

Technical Field

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

[0002] Transformers are divided into dry-type transformers and wet-type transformers. Among them, the wet-type transformer is an electrical device that uses the principle of electromagnetic induction and oil as a cooling medium to achieve voltage transformation. Working principle of the wet-type transformer: When high voltage passes through one side winding of the transformer, a corresponding low voltage will be induced in the other side winding (or vice versa, changing low voltage to high voltage). This is because the current in the winding generates a magnetic field, and the change of the magnetic field induces a voltage in the other side winding. At the same time, heat is generated when the current passes through the winding, and the oil in the fuel tank plays a role in heat dissipation to prevent the winding from overheating.

[0003] However, there are some deficiencies in the existing wet-type transformers during use, which are as follows: During the operation of the existing wet-type transformer, a circulating fuel tank is installed on the outside of the transformer, a fan and heat sinks are installed on the outside of the transformer, and the heat absorbed by the cooling oil inside the transformer is dissipated through the fan and heat sinks, so as to achieve the purpose of cooling the temperature of the transformer. And when the temperature is too high, the cooling oil in the fuel tank is replaced with the cooling oil in the transformer to achieve the purpose of controlling the temperature of the transformer. However, during the operation of the existing transformer, it is difficult to adjust the temperature control in real time according to the change of temperature by the fan and the fuel tank, and it cannot adjust the cooling power according to the working intensity of the transformer. Therefore, it is not convenient to save the cooling cost during the operation of the transformer. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a transformer for a submersible electric pump on an offshore platform to solve the problems existing in the above background art.

[0010] Further, the height of the positioning groove and the height of the first square tube are in clearance fit.

The length of the spiral plate is the same as the length inside the main body of the fuel tank. The connection position of the second diversion pipe and the main body of the fuel tank is located inside the spiral plate.

[0013] Technical effects and advantages of the present invention: During the operation of the transformer in the present invention, due to the operation of the winding, its temperature rises, causing the temperature of the cooling oil inside the transformer casing to gradually increase. During the gradual increase of the cooling oil temperature, the volume of the cooling oil will expand. And because the inside of the transformer casing is in a sealed state, when the volume of the cooling oil expands, it will push the first sliding block and the inductor slider to slide inside the first square pipe and the inductor slide rail. During the sliding of the first sliding block and the inductor slider, the oil pipelines will be moved to the right side of the first sliding block and the inductor slider one by one. And the power of the oil pump assembly increases as the inductor slider moves closer to the left inside the inductor slide rail. Thus, during the gradual increase of the temperature inside the transformer, the oil pipelines will gradually be located on the right side of the second sliding block and the first sliding block, and the flow rate of the hydraulic oil inside the first diversion pipe becomes faster, increasing the replacement speed between the cooling oil with a higher temperature inside the transformer and the hydraulic oil with a lower temperature inside the main body of the fuel tank. Therefore, the temperature of the hydraulic oil inside the transformer assembly is effectively controlled, ensuring that the operating temperature of the transformer is maintained within a safe range.

[0014] During the use of the transformer of the present invention, the temperature inductor assembly, the heat dissipation assembly, and the inside of the second square tube are filled with cooling oil, and there is air in the buffer round tube and the air pressure assembly. When the cooling oil expands inside the transformer housing, the first sliding block and the inductor slider move to the left, so that part of the hydraulic oil on the left side of the first sliding block enters the buffer round tube. When the first sliding block moves to the left and the oil pipeline is exposed, the liquid level inside the buffer round tube will drop to the original position under the action of gravity, and part of the cooling oil on the left side of the first sliding block and the second sliding block enters the transformer housing. And because the inductor slider moves to the left, the power of the oil pump assembly increases, so that the liquid entering the second square tube per unit time increases, which makes the second sliding block move to the left, and then the liquid level of the buffer round tube rises, and then drops to the original position during the movement of the first sliding block again. Therefore, as the temperature inside the transformer housing increases, the number of oil pipelines added to the circulating oil circuit increases, enabling the device to adjust the working efficiency of the cooling oil circuit according to temperature changes, facilitating the autonomous adjustment of the device.

[0015] During the process of the working temperature of the device of the present invention gradually decreasing, the volume of the cooling oil inside the device will gradually decrease, so that the first sliding block moves to the right. When the first sliding block moves to the right by the distance of one oil pipeline, the air pressure assembly works to inject air into the buffer round 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 one oil pipeline, and then the injected air is discharged by the work of the air pressure assembly, and then the above work is repeated until the second sliding block and the first sliding block return to the original position, enabling the device to reset itself. And the air injected by the air pressure assembly will be blocked by the third stop block, preventing the gas from directly entering the oil circuit circulation and ensuring the normal use of the device.

[0016] When the inductor slider is located in the right half section of the present invention, only the fan assembly on the right works to inject gas into the air guide housing through the air outlet, and the temperature of the oil pipeline is taken away through the outside of the oil pipeline, so that the cooling oil can be effectively cooled when passing through the oil pipeline, and then injected into the fuel tank main body, enabling the device to work continuously for a long time and facilitating the stabilization of the temperature during the operation of the device.

[0017] When the cooling oil enters the inside of the fuel tank main body of the present invention, it moves along with the guidance of the spiral plate, and the cooling oil conveyed by the second diversion pipe is the cooling oil located in the innermost part of the fuel tank main body, which can effectively isolate the temperature of the cooling oil. When the transformer works at a high intensity for a long time, it can effectively reduce the rising speed of the temperature of the cooling oil. And when the second sliding block moves to the left, the diversion telescopic pipe will gradually extend to ensure the normal use of the oil circuit control assembly. Description of the Drawings

Detailed implementation manners

[0028] The technical solutions in 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, and the transformer for a submersible electric pump on an offshore platform involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0029] Referring to Figures 1 to 9 , the present invention provides a transformer for a submersible electric pump on an offshore platform, including a transformer assembly 1. Temperature inductance assemblies 2 are fixedly connected to the bottoms of the front and back sides of the transformer assembly 1. Heat dissipation assemblies 3 are fixedly connected to the tops of the front and back sides of the transformer assembly 1 at positions where the temperature inductance assemblies 2 are located. Oil circuit control assemblies 4 are fixedly connected to the tops of the front and back sides of the transformer assembly 1. A fuel tank assembly 5 is fixedly connected to one side of the transformer assembly 1. The transformer assembly 1 includes a transformer housing 101. An iron core 102 is arranged inside the transformer housing 101. A winding 103 is installed outside the iron core 102. Positioning grooves 104 are formed at the bottoms of the front and back sides of the transformer housing 101. A wiring post 105 is fixedly connected to the top of the iron core 102. Fan assemblies 106 are fixedly connected to both sides of the transformer housing 101. Air outlets 107 are fixedly connected to the front and back sides of the fan assemblies 106. During the use of the transformer, the temperature inductance assemblies 2, the heat dissipation assemblies 3, and the inside of the second square tube 401 are filled with cooling oil, and there is air in the buffer round tube 403 and the air pressure assembly 404. When the cooling oil expands inside the transformer housing 101, the first sliding block 205 and the inductance slider 206 move to the left, so that part of the hydraulic oil on the left side of the first sliding block 205 enters the buffer round tube 403. When the first sliding block 205 moves to the left and the oil circuit pipe 302 is exposed, the liquid level inside the buffer round tube 403 will drop to the original position under the action of gravity, and part of the cooling oil on the left side of the first sliding block 205 and the second sliding block 406 enters the transformer housing 101. And because the inductance 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, which makes the second sliding block 406 move to the left, and then the liquid level of the buffer round tube 403 rises, and then drops to the original position during the next movement of the first sliding block 205. Thus, as the temperature inside the transformer housing 101 rises, the number of oil circuit pipes 302 added to the circulating oil circuit increases, enabling the device to adjust the working efficiency of the cooling oil circuit according to temperature changes, facilitating the autonomous adjustment of the device.

[0030] In a preferred embodiment, the temperature inductor assembly 2 includes a first square tube 201. An inductor slide rail 202 is fixedly connected to the top of the first square tube 201. A first oil path positioning round hole 203 is opened at the top of the first square tube 201. A conduction notch 207 is opened on one side of the back surface of the first square tube 201. A first stop block 204 is fixedly connected to one side inside the conduction notch 207. A first sliding block 205 is arranged inside the first square tube 201. An inductor slider 206 is fixedly connected to the top of the first sliding block 205. During the operation of the transformer, due to the operation of the winding 103, its temperature rises, causing the temperature of the cooling oil inside the transformer housing 101 to gradually increase. During the gradual increase of the cooling oil temperature, the volume of the cooling oil expands. And because the inside of the transformer housing 101 is in a sealed state, when the volume of the cooling oil expands, it 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 of the first sliding block 205 and the inductor slider 206, the oil path tubes 302 will be moved to the right side of the first sliding block 205 and the inductor slider 206 one by one. And the power of the oil pump assembly 506 increases as the inductor slider 206 approaches the left side inside the inductor slide rail 202. Thus, during the gradual increase of the temperature inside the transformer, the oil path tubes 302 will gradually be located on the right side of the second sliding block 406 and the first sliding block 205, and the flow rate of the hydraulic oil inside the first diversion tube 407 will become faster, increasing the replacement rate between the cooling oil with a higher temperature inside the transformer and the hydraulic oil with a lower temperature inside the tank body 502. 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.

[0031] In a preferred embodiment, the heat dissipation assembly 3 includes a wind guiding housing 301. An oil path tube 302 is installed inside the wind guiding housing 301. Air inlet slots 303 are opened on both sides of the wind guiding housing 301. A square slot 305 is opened on the side of the wind guiding housing 301 away from the transformer assembly 1. Arc-shaped notches 304 are opened on both sides of the square slot 305. When the inductor slider 206 is located in the right half section, only the right fan assembly 106 works to inject gas into the wind guiding housing 301 through the air outlet 107, and the temperature of the oil path tube 302 will be taken away after passing through the outside of the oil path tube 302. Thus, the cooling oil can be effectively cooled when passing through the oil path tube 302, and then injected into the tank body 502, enabling the device to work continuously for a long time and facilitating the stabilization of the temperature during the operation of the device.

[0032] In a preferred embodiment, the oil circuit control assembly 4 includes a second square tube 401. A second oil circuit positioning round hole 402 is provided at the top of the second square tube 401. A buffer round tube 403 is installed on one side of the top of the second square tube 401. A pneumatic assembly 404 is fixedly connected to the top of the buffer round tube 403. An extraction groove 4011 is provided inside the second square tube 401. A sliding notch 4012 is fixedly connected to the back of the second square tube 401. Rotation positioning grooves 4013 are provided at the top and bottom of the sliding notch 4012 and on the side wall of the second square tube 401. A rotation belt 405 is arranged inside the rotation positioning groove 4013. Rotation limit belts 409 are fixedly connected to the top and bottom of the rotation belt 405. A second sliding block 406 is installed on the outer side of the rotation belt 405. A second stop block 4010 is installed on one side inside the extraction groove 4011. A third stop block 4014 is fixedly installed on the other side inside the extraction groove 4011. A first diversion pipe 407 is fixedly connected to the side of the second sliding block 406 away from the second square tube 401. A diversion telescopic pipe 408 is fixedly connected to one side of the first diversion pipe 407; during the process of the working temperature of the device gradually decreasing, the volume of the cooling oil inside the device will gradually decrease, thereby causing the first sliding block 205 to move to the right. When the first sliding block 205 moves a distance of one oil circuit pipe 302 to the right, the pneumatic assembly 404 works to inject air into the buffer round tube 403. Under the action of the atmospheric pressure inside the second square tube 401, the second sliding block 406 moves a distance of one oil circuit pipe 302 to the right. Then, the injected air is discharged by the working of the pneumatic assembly 404, and then the above work is repeated until the second sliding block 406 and the first sliding block 205 return to their original positions, enabling the device to automatically reset. Moreover, the air injected by the pneumatic assembly 404 will be blocked by the third stop block 4014, preventing the gas from directly entering the oil circuit circulation and ensuring the normal use of the device.

[0033] In a preferred embodiment, the fuel tank assembly 5 includes a fixing plate 501. A fuel tank main body 502 is fixedly connected to the top of the fixing plate 501. A spiral plate 503 is fixedly connected to the inside of the fuel tank main body 502. Second diversion pipes 504 are fixedly connected to the front and back of the fuel tank main body 502. Third diversion pipes 505 are fixedly connected to the front and back of the bottom of the fixing plate 501. The other side of the third diversion pipe 505 is fixedly connected to an oil pump assembly 506. A fourth diversion pipe 507 is fixedly connected to the top of the oil pump assembly 506; when the cooling oil enters the inside of the fuel tank main body 502, it moves along with the guidance of the spiral plate 503, and the cooling oil conveyed by the second diversion pipe 504 is the cooling oil located at the innermost side of the fuel tank main body 502, which can effectively isolate the temperature of the cooling oil. When the transformer works at a high intensity for a long time, it can effectively reduce the rising speed of the temperature of the cooling oil. Moreover, when the second sliding block 406 moves to the left, the diversion telescopic pipe 408 will gradually elongate to ensure the normal use of the oil circuit control assembly 4.

[0034] In a preferred embodiment, there is a clearance fit between the height of the positioning groove 104 and the height of the first square tube 201. The surface of the first square tube 201 where the conduction notch 207 is opened is in the same plane as the inner side of the positioning groove 104. There is a clearance fit between the cross-sectional dimension inside the first square tube 201 and the cross-sectional dimension of the first sliding block 205. There is a clearance fit between the width inside the inductor slide rail 202 and the width of the inductor slider 206. There is a clearance fit between the distance between the top inside the first square tube 201 and the top of the inductor slide rail 202 and the height of the inductor slider 206.

[0035] In a preferred embodiment, there is a clearance fit between the diameter of the oil pipeline 302 and the diameter of the first oil pipeline positioning round hole 203. There is a clearance fit between the diameter of the oil pipeline 302 and the diameter of the second oil pipeline positioning round hole 402. The center line of the square groove 305 overlaps with the center line of the oil pipeline 302 in the orthographic projection. The center of the arc-shaped notch 304 coincides with the center of the oil pipeline 302. There is a clearance fit between the size of the air inlet groove 303 and the size of the air outlet 107.

[0036] In a preferred embodiment, there is a clearance fit between the outer dimension of the cross-section of the second sliding block 406 and the cross-sectional dimensions of the extraction groove 4011 and the sliding notch 4012. There is a clearance fit between the cross-sectional dimension of the rotation positioning groove 4013 and 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 inside the fuel tank main body 502. The connection position of the second diversion pipe 504 and the fuel tank main body 502 is located inside the spiral plate 503.

[0037] Working principle of the present invention: During the operation of the transformer, the temperature of the winding 103 rises during operation, causing the temperature of the cooling oil inside the transformer housing 101 to gradually increase. During the gradual increase in the temperature of the cooling oil, the volume of the cooling oil expands. Since the inside of the transformer housing 101 is in a sealed state, when the volume of the cooling oil expands, it will push the first sliding block 205 and the inductance slider 206 to slide inside the first square tube 201 and the inductance slide rail 202. During the sliding of the first sliding block 205 and the inductance slider 206, the oil pipeline 302 will be moved to the right side of the first sliding block 205 and the inductance slider 206 one by one, and the power of the oil pump assembly 506 increases as the inductance slider 206 moves closer to the left inside the inductance slide rail 202. Thus, during the gradual increase in the internal temperature of the transformer, the oil pipeline 302 will gradually be located on the right side of the second sliding block 406 and the first sliding block 205, and the flow rate of the hydraulic oil inside the first diversion pipe 407 will become faster, increasing the replacement rate between the cooling oil with a higher temperature inside the transformer and the hydraulic oil with a lower temperature inside the main body of the fuel tank 502. Therefore, the temperature of the hydraulic oil inside the transformer assembly 1 is effectively controlled, ensuring that the operating temperature of the transformer is maintained within a safe range; During the use of the transformer, the temperature inductor assembly 2, the heat dissipation assembly 3, and the inside of the second square tube 401 are filled with cooling oil, and there is air in the buffer round tube 403 and the air pressure assembly 404. When the cooling oil inside the transformer housing 101 expands, the first sliding block 205 and the inductance slider 206 move to the left, causing some of the hydraulic oil on the left side of the first sliding block 205 to enter the buffer round tube 403. When the first sliding block 205 moves to the left and the oil pipeline 302 is exposed, the liquid level inside the buffer round tube 403 will drop to the original position under the action of gravity, and some of the cooling oil on the left side of the first sliding block 205 and the second sliding block 406 will enter the transformer housing 101. Since the inductance slider 206 moves to the left, the power of the oil pump assembly 506 increases, causing the amount of liquid entering the second square tube 401 per unit time to increase, which makes the second sliding block 406 move to the left, and then the liquid level of the buffer round tube 403 rises, and then drops to the original position during the subsequent movement of the first sliding block 205. Thus, as the temperature inside the transformer housing 101 increases, the number of oil pipelines 302 added to the circulating oil circuit increases, enabling the device to adjust the working efficiency of the cooling oil circuit according to temperature changes, facilitating autonomous adjustment of the device; During the process of the working temperature of the device gradually decreasing, the volume of the cooling oil inside the device will gradually decrease, causing the first sliding block 205 to move to the right. When the first sliding block 205 moves a distance equal to that of an oil pipeline 302 to the right, the air pressure component 404 works to inject air into the inside of the buffer circular tube 403. Under the action of the atmospheric pressure inside the second square tube 401, the second sliding block 406 moves a distance equal to that of an oil pipeline 302 to the right. Then, the injected air is discharged by the operation of the air pressure component 404, and then the above work is repeated until the second sliding block 406 and the first sliding block 205 return to their original positions, enabling the device to reset itself. Moreover, the air injected by the air pressure component 404 is blocked by the third stop block 4014, preventing the gas from directly entering the oil circuit circulation and ensuring the normal use of the device; When the inductive slider 206 is located in the right half section, only the blower assembly 106 on the right works to inject gas into the air guide housing 301 through the air outlet 107 and take away the temperature of the oil pipeline 302 through the outside of the oil pipeline 302. As a result, the cooling oil can be effectively cooled when passing through the oil pipeline 302, and then injected into the fuel tank main body 502, enabling the device to work continuously for a long time and facilitating the stabilization of the temperature during the operation of the device; When the cooling oil enters the inside of the fuel tank main body 502, it moves along the guidance of the spiral plate 503, and the cooling oil delivered by the second diversion pipe 504 is the cooling oil located at the innermost side of the fuel tank main body 502, which can effectively isolate the temperature of the cooling oil. When the transformer works at a high intensity for a long time, it can effectively reduce the rising speed of the temperature of the cooling oil. Moreover, when the second sliding block 406 moves to the left, the diversion telescopic pipe 408 will gradually elongate to ensure the normal use of the oil circuit control assembly 4.
