Description
Technical Field
[0001] This application relates to the field of power transformer technology, and more specifically, to a power transformer with a short-circuit alarm function. Background Technology
[0002] Currently, my country is vigorously promoting the application of power transformers with short-circuit alarm functions. As is well known, a power transformer is a static electrical device used to convert a certain value of alternating voltage (current) into one or more different values of voltage (current) with the same frequency. When alternating current is applied to the primary winding, an alternating magnetic flux is generated. This alternating magnetic flux, through the magnetic conduction of the iron core, induces an alternating electromotive force (EMF) in the secondary winding. The magnitude of the induced EMF in the secondary winding is related to the number of turns in both the primary and secondary windings; that is, the voltage magnitude is positively correlated with the number of turns. However, short circuits can occur in power transformers during use. If an alarm is not triggered in time, it will have a significant impact on user experience.
[0003] Because current power transformers with short-circuit alarm functions cannot effectively reduce internal pressure when a short circuit occurs, and the temperature rises sharply along with the increased pressure, the transformer faces the risk of fire during a short circuit. Furthermore, commonly used short-circuit alarms may malfunction in extreme environments. Therefore, power transformers with short-circuit alarm functions currently on the market pose a safety hazard when a short circuit occurs. Summary of the Invention

Two sets of springs four are fixedly connected to the bottom inner side of the outer shell two, and a lifting plate is fixedly connected above the two sets of springs four. A sliding door is slidably connected to the top of the outer shell two.

[0014] The advantages of this application are: (1) This application sets up a moving platform and a triangular plate so that when the transformer is short-circuited, the oil inside the transformer enters the cavity one from the opening one. Due to the pressure change, the pressure plate drives the moving platform to move upward. When the moving platform moves to the corresponding position, the moving platform squeezes the triangular plate, causing the triangular plate to move towards the cavity two. The triangular plate drives the baffle to open the opening two. The oil enters the cavity two through the opening two. When the transformer returns to normal, the moving platform returns to its original position due to the tension of the spring one, and the triangular plate returns to its original position at the same time, so that the baffle can block the opening two again. The tension of the spring three causes the push plate to move towards the cavity one. The oil in the cavity two can return to the inside of the transformer through the one-way valve, so as to relieve the internal pressure of the transformer when the transformer is short-circuited.
[0015] (2) By setting up an extrusion plate and a loading plate, the extrusion plate presses the outer shell II upward through the irregular connecting rod while the moving platform is rising, causing the outer shell II to tilt and sprinkle the heat-conducting powder inside the outer shell II onto the loading plate. At the same time, the moving platform gradually returns to a horizontal state due to the tilt of the outer shell II. When the pressure plate passes through the two sets of rubber extrusion plates, the moving platform will generate a sudden upward force. Through the impact between the moving platform and the impact rod, the loading plate will generate an upward force, so that the heat-conducting powder in the loading plate can be evenly sprinkled above the transformer. Through the cooperation of the heat-conducting powder and the heat dissipation matrix, the transformer can dissipate heat to avoid fire. At the same time, the sprinkled powder can also serve as a warning of transformer short circuit.
[0016] (3) By setting up collision blocks and electric rotating rods, the electric rotating rods can move together with the outer shell 2 through two sets of irregular baffles. The rotation of the electric rotating rods can drive the four sets of outer shell 3. The collision blocks on the inner side of the outer shell 3 hit the movable platform, causing the movable platform and the loading plate to vibrate, so as to achieve the purpose of more evenly distributing the powder sprinkled from the outer shell 2 onto the loading plate.

[0025] Example 1, see Figures 1-5 This embodiment provides a power transformer with a short-circuit alarm function, including a transformer 100, an alarm device 200 mounted on the outside of the transformer 100, a radiator 300 mounted on the outside of the transformer 100, and a heat dissipation matrix 400 mounted on the outside of the radiator 300 above the transformer 100. The transformer 100 is fitted with a housing 101 on its outer side. A cavity 102 and a cavity 103 are sequentially formed on the inner side of the housing 101. An opening 104 is formed on the outer side of cavity 102 and on the inner side of housing 101, communicating with the oil tank inside the transformer 100. A pressure plate 105 is slidably connected to the inner side of housing 101 and inside cavity 102. A round rod 106 is fixedly connected above the pressure plate 105. A partition 107 is fixedly connected to the inner side of housing 101 and on the outer side of round rod 106. A movable plate is fixedly connected above round rod 106. Two sets of springs 109 are fixedly connected between the platform 108 and the partition 107. A rubber extrusion plate 110 is fixedly connected inside the outer shell 101 and between the partition 107 and the pressure plate 105. The two sets of rubber extrusion plates 110 are arranged in an arc shape in corresponding directions and are respectively located inside the outer shell 101 and on both sides of the pressure plate 105. A slide rod 202 is slidably connected inside the outer shell 101 and between the cavity 102 and the cavity 203. A triangular plate 201 is slidably connected to the left side of the slide rod 202. The triangular plate 201 is connected to the inner side of the outer shell 101. A spring 203 is fixedly connected. A rubber baffle 205 is fixedly connected to the upper inner side of the outer shell 101 and to the right of the triangular plate 201. The triangular plate 201 is positioned above the moving platform 108, and the side of the triangular plate 201 closest to the moving platform 108 is set with an inclined structure. The rubber baffle 205 is set with an arc-shaped structure. A connecting rod 204 is fixedly connected to the outer side of the slide rod 202 and inside the cavity 103. A baffle 206 is fixedly connected below the connecting rod 204. An opening 111 is provided on the inner side of the outer shell 101 between the cavity 102 and the cavity 103. An oil draining device 301 is installed on the inner side of the outer casing 101. The oil draining device 301 includes a push plate 302, which is slidably connected to the inner side of the outer casing 101. A push rod 303 is fixedly connected to the outer side of the push plate 302. The push rod 303 passes through the right side of the outer casing 101. A circular baffle 304 is fixedly connected to the outer side of the push rod 303. A spring 305 is fixedly connected between the circular baffle 304 and the outer casing 101. A one-way valve 306 is installed on the inner side of the outer casing 101 between the push plate 302 and the baffle 206. The opening of the one-way valve 306 communicates with the oil tank inside the transformer 100.This application, by setting up a movable platform 108 and a triangular plate 201, allows oil inside the transformer 100 to enter the cavity 102 through opening 104 when the transformer 100 is short-circuited. Due to the increased pressure, the pressure plate 105 drives the movable platform 108 to move upwards. When the movable platform 108 reaches the corresponding position, it presses against the triangular plate 201, causing the triangular plate 201 to move towards the cavity 103. This causes the triangular plate 201 to drive the baffle 206, opening the second opening 111, allowing oil to pass through. When the second opening 111 enters the second cavity 103, and the transformer 100 returns to normal, the moving platform 108 returns to its original position due to the tension of the first spring 109, and the triangular plate 201 returns to its original position, so that the baffle 206 can block the second opening 111 again. The push plate 302 moves towards the first cavity 102 due to the tension of the third spring 305, and the oil in the second cavity 103 can return to the inside of the transformer 100 through the one-way valve 306, so as to relieve the internal pressure of the transformer 100 when the transformer 100 is short-circuited.
[0026] In practical use, the above-mentioned equipment has an opening 104 on the outside of cavity 102 and inside the outer shell 101, and the opening 104 is connected to the oil tank inside the transformer 100. This allows oil from inside the transformer 100 to enter cavity 102 through the opening 104. A pressure plate 105 is slidably connected inside the outer shell 101 and inside cavity 102. When the pressure in the oil tank inside the transformer 100 increases due to a short circuit, the pressure plate 105 moves upward due to the increased pressure below cavity 102. A partition 107 is fixedly connected inside the outer shell 101 and outside the round rod 106, preventing oil below cavity 102 from entering above cavity 102 through partition 107. This system limits the movement of pressure plate 105. A round rod 106 is fixedly connected above pressure plate 105, and a moving platform 108 is fixedly connected above the round rod 106. When pressure plate 105 moves, it drives the round rod 106 and the moving platform 108 to move together. Two sets of springs 109 are fixedly connected between the moving platform 108 and partition plate 107. When transformer 100 returns to normal operation, the pressure below cavity 102 decreases, and pressure plate 105 returns to its initial position due to the tension of the two sets of springs 109. An opening 111 is opened inside outer casing 101, between cavity 102 and cavity 103, allowing oil in cavity 102 to enter cavity 103 through opening 111. A sliding rod 202 is slidably connected to the inner side of the outer shell 101 and between the first cavity 102 and the second cavity 103. A triangular plate 201 is slidably connected to the left side of the sliding rod 202. A rubber baffle 205 is fixedly connected to the upper inner side of the outer shell 101 and to the right side of the triangular plate 201. The triangular plate 201 is positioned above the moving platform 108, with the side of the triangular plate 201 closest to the moving platform 108 having an inclined structure. The rubber baffle 205 has an arc-shaped structure. When the moving platform 108 reaches the corresponding position, it compresses the triangular plate 201, causing the rubber baffle 205 to deform under the pressure of the moving platform 108. This allows the triangular plate 201 to pass through the rubber baffle 205. Simultaneously, the triangular plate 201 can drive... The slide rod 202 moves towards cavity 103. A connecting rod 204 is fixedly connected to the outside of the slide rod 202 and inside cavity 103, and a baffle 206 is fixedly connected below the connecting rod 204. When the slide rod 202 moves towards cavity 103, it drives the connecting rod 204 and the baffle 206 to move together, thus opening opening 111 and allowing oil from cavity 102 to enter cavity 103. A spring 203 is fixedly connected between the triangular plate 201 and the inside of outer casing 101. When the transformer 100 returns to normal operation, the triangular plate 201 and the baffle 206 can return to their initial positions due to the spring force of the spring 203, thus allowing the baffle 206 to block opening 111 again.By sliding the push plate 302 to the inside of the outer casing 101, the push plate 302 moves to the right due to the pressure of the oil entering the cavity 103. When the transformer 100 returns to normal, the pressure inside the transformer 100 returns to normal, while the internal pressure remains unchanged. This allows the transformer oil to re-enter the transformer 100 through the one-way valve 306. A spring 305 is fixedly connected between the circular baffle 304 and the outer casing 101, making the oil drainage process more stable and faster. This design effectively alleviates the internal pressure of the transformer 100 during a short circuit.
[0027] Example 2, see Figures 6-7In this embodiment, based on Embodiment 1, a non-circular connecting rod 401 is fixedly connected to the top of the mobile platform 108, and a pressing plate 402 is fixedly connected to the outer side of the non-circular connecting rod 401. Two sets of fixing plates 403 are fixedly connected to the top of the outer shell 101, and an outer shell 404 is rotatably connected between the two sets of fixing plates 403. Two sets of springs 405 are fixedly connected to the bottom inner side of the outer shell 404, and a lifting plate 406 is fixedly connected above the two sets of springs 405. A sliding door 407 is slidably connected to the top of the outer shell 404. An opening 408 is provided on the outer side of the outer shell 404, and a guide plate 409 is fixedly connected to the outer side of the outer shell 404 and below the opening 408. A support plate 410 is fixedly connected to the top of the outer shell 101. A movable platform 411 is hinged above the 10. Two sets of telescopic rods 412 are fixedly connected above the movable platform 411. A loading plate 413 is fixedly connected above the two sets of telescopic rods 412. The width of the opening 3 408 is equal to the width of the guide plate 409, and the width of the opening 3 408 is equal to the width of the loading plate 413. A handle is provided on the outside of the sliding door 407, and the edges of the handle are all set with curved surfaces. Multiple loading slots 414 are opened above the loading plate 413. A U-shaped baffle is provided around the loading plate 413, and the multiple loading slots 414 are evenly opened above the loading plate 413. The loading plate 413 is inclined above the movable platform 411. An impact rod 415 is fixedly connected to the outside of the loading plate 413 and the side close to the cavity 102. This application, by setting up an extrusion plate 402 and a loading plate 413, allows the moving platform 108 to rise while the extrusion plate 402, through the irregular connecting rod 401, extrudes the outer shell 404 upwards, causing the outer shell 404 to tilt and spray the heat-conducting powder inside the outer shell 404 onto the loading plate 413. At the same time, the moving platform 411 gradually returns to a horizontal state due to the tilt of the outer shell 404. When the pressure plate 105 passes through the two sets of rubber extrusion plates 110, the moving platform 108 generates a sudden upward force. Through the impact between the moving platform 108 and the impact rod 415, the loading plate 413 generates an upward force, allowing the heat-conducting powder inside the loading plate 413 to be evenly sprayed above the transformer 100. Through the cooperation of the heat-conducting powder and the heat dissipation matrix 400, the transformer 100 dissipates heat to avoid fire. At the same time, the sprayed powder can also serve as a warning of short circuit in the transformer 100.
[0028] In practical use, the above-mentioned equipment utilizes a shaped connecting rod 401 fixedly connected above the moving platform 108, allowing the moving platform 108 to move the shaped connecting rod 401. A pressing plate 402 is fixedly connected to the outside of the shaped connecting rod 401, allowing the shaped connecting rod 401 to move the pressing plate 402. Two sets of fixing plates 403 are fixedly connected above the outer shell 101, and an outer shell 404 is rotatably connected between the two sets of fixing plates 403, allowing the outer shell 404 to swing left and right. Two sets of springs 405 are fixedly connected to the bottom inner side of the outer shell 404, and a lifting plate 406 is fixedly connected above the two sets of springs 405, allowing the lifting plate 406 to slide above the outer shell 404. A sliding door 407 is dynamically connected, and a handle is provided on the outside of the sliding door 407. The edges of the handle are all designed with a curved structure, allowing the operator to open the sliding door 407 through the handle and place the heat-conducting powder above the lifting plate 406. As the heat-conducting powder above the lifting plate 406 gradually decreases, the lifting plate 406 can be kept in the same position due to the force of the two sets of springs 405. An opening 408 is opened on the outside of the outer shell 2 404, and a guide plate 409 is fixedly connected to the outside of the outer shell 2 404 and below the opening 408. The heat-conducting powder inside the outer shell 2 404 can be discharged from the outer shell 2 404 through the opening 408 and along the guide plate 409. A support is fixedly connected above the outer shell 1 101. A support plate 410 is provided, and a movable platform 411 is hinged above the support plate 410, allowing the movable platform 411 to swing above the support plate 410. Two sets of telescopic rods 412 are fixedly connected above the movable platform 411, and a loading plate 413 is fixedly connected above the two sets of telescopic rods 412. When the movable platform 108 swings, the two sets of telescopic rods 412 and the loading plate 413 swing together. As the movable platform 108 rises, the extrusion plate 402 extrudes the outer shell 404 upward through the irregular connecting rod 401, causing the outer shell 404 to tilt and sprinkle the heat-conducting powder inside the outer shell 404 onto the loading plate 413. At the same time, the movable platform 411 gradually returns to a horizontal state due to the tilt of the outer shell 404. Multiple assembly slots 414 are opened above the loading plate 413, and U-shaped baffles are provided around the loading plate 413. The multiple assembly slots 414 are evenly distributed above the loading plate 413, so that the heat dissipation powder is more evenly distributed above the loading plate 413. By tilting the loading plate 413 above the movable platform 411, and fixing the impact rod 415 to the outer side of the loading plate 413 and the side close to the cavity 102, the moving platform 108 will generate a sudden upward force when the pressure plate 105 passes through the two sets of rubber extrusion plates 110. Through the impact of the moving platform 108 and the impact rod 415, the loading plate 413 generates an upward force, so that the heat-conducting powder in the loading plate 413 can be evenly sprinkled above the transformer 100.By ensuring thorough adhesion between the thermally conductive powder and the heat dissipation matrix 400, heat dissipation is achieved, preventing fire. Simultaneously, the scattered powder also serves as a warning of a short circuit in the transformer 100.
[0029] Example 3, see Figures 8-9 In this embodiment, based on embodiment one, two sets of irregularly shaped baffles 501 are fixedly connected to the lower part of the outer shell 2 404. An electric rotating rod 502 is assembled between the two sets of irregularly shaped baffles 501. Four sets of outer shells 3 503 are assembled on the outer side of the electric rotating rod 502. A collision block 504 is slidably connected to the inner side of the outer shell 3 503. The four sets of outer shells 3 503 are evenly assembled on the outer side of the electric rotating rod 502 with the electric rotating rod 502 as the center. The upper end of the collision block 504 is set as an arc structure. Two sets of round rods 2 505 are fixedly connected to the lower part of the collision block 504. A circular baffle 2 506 is fixedly connected to the lower part of each of the two sets of round rods 2 505. A fixing plate 2 507 is fixedly connected to the inner side of the outer shell 3 503 and to the outer side of the two sets of round rods 2 505. A spring 508 is fixedly connected between each of the two sets of circular baffles 2 506 and the fixing plate 2 507. This application sets up a collision block 504 and an electric rotating rod 502, so that the electric rotating rod 502 can move together with the outer shell 404 through two sets of irregular baffles 501. The rotation of the electric rotating rod 502 drives the four sets of outer shells 503. The collision block 504 on the inner side of the outer shell 503 impacts the movable platform 411, causing the movable platform 411 and the loading plate 413 to vibrate, so that the powder sprinkled from the outer shell 404 onto the loading plate 413 can be more evenly distributed on the loading plate 413.
[0030] In practical use, the above-mentioned equipment uses two sets of irregularly shaped baffles 501 fixedly connected to the lower part of the outer casing 404. The movement of the outer casing 404 drives the movement of the two sets of irregularly shaped baffles 501. An electric rotating rod 502 is installed between the two sets of irregularly shaped baffles 501, and four sets of outer casings 503 are installed on the outside of the electric rotating rod 502. The movement of the two sets of irregularly shaped baffles 501 drives the electric rotating rod 502 and the four sets of outer casings 503 together. Activating the electric rotating rod 502 allows the four sets of outer casings 503 to rotate around it. A collision block 504 is slidably connected to the inner side of the outer casing 503. When the collision block 504 collides with the movable platform 411, the movable platform 411 will press the collision block 504 towards the electric rotating rod 502. Two sets of round rods 505 are fixedly connected to the bottom of the 04, and round baffles 506 are fixedly connected to the bottom of the two sets of round rods 505. When the collision block 504 moves, it can drive the two sets of round rods 505 and the two sets of round baffles 506 to move together. By fixing plates 507 are fixedly connected to the inside of the outer shell 3 503 and the outside of the two sets of round rods 505, and springs 508 are fixedly connected between the two sets of round baffles 506 and the fixing plates 507, when the moving platform 411 stops pressing the collision block 504, the collision block 504 can return to its original position due to the tension of the springs 508. Through the continuous impact of the four sets of collision blocks 504 on the moving platform 411, the powder sprinkled from the outer shell 2 404 onto the loading plate 413 can be more evenly distributed on the loading plate 413.
