Description

Technical Field

[0001] The invention relates to the field of wind power transformers, in particular to a wind power transformer with good waterproof performance. Background Art

[0002] As a key device in the wind power generation system, wind power transformers are responsible for stepping up or down the voltage of the electricity generated by wind turbines to meet the needs of grid access and transmission. Wind power transformers are usually installed in outdoor environments and are directly exposed to various weather conditions, especially in extreme weather such as rainstorms and typhoons. The stability and safety of their operation must still be guaranteed;

[0003] The external transformer selects the appropriate core diameter according to the cost of the core silicon steel sheet and the winding copper wire to manufacture the product, reducing the cost while meeting the technical parameters; the high and low voltage switch cabinets can be arranged on the same horizontal plane as the transformer body and placed in a large shell, which is convenient for manufacturing, transportation, lifting, on-site installation and future maintenance; the cooling method adopts AN / AF, and the fan is placed under the transformer body, which has a simple cooling method, high cooling efficiency and low cost;

[0004] However, traditional wind power transformers have certain waterproof properties, but in extreme weather with heavy rainfall such as rainstorms, traditional waterproof measures are often unable to completely prevent the intrusion of large amounts of rainwater, resulting in rainwater invading the interior of the transformer, causing short circuits and corrosion of electrical components, and affecting the performance of the wind power transformer. In addition, rainwater may penetrate into the interior of the transformer through the gaps between the doors, and impurities and conductive substances in the water may adhere to the surface of the insulating material. Over time, a conductive path is formed, resulting in a decrease in insulation resistance, thereby reducing the insulation performance of the transformer, which may cause safety hazards when subsequent staff open the door to perform equipment maintenance or overhaul.

[0005] Therefore, we propose a wind power transformer with good waterproof performance. Summary of the invention

[0006] In order to make up for the shortcomings of the existing technology and solve the problem that traditional waterproof measures are often difficult to completely block the intrusion of a large amount of rainwater, and rainwater may invade the inside of the transformer through the gaps between the doors, a wind power transformer with good waterproof performance is proposed.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a wind power transformer with good waterproof performance, comprising a wind power transformer main body, a transformer box top cover is arranged at the top of the wind power transformer main body, a surface of the transformer box top cover is symmetrically provided with water receiving grooves, a water inlet groove is arranged at the bottom end of the two water receiving grooves, a water flow groove is arranged at the bottom end of the water inlet groove, a first water storage square tube is fixedly connected to the bottom end of the transformer box top cover, the water flow groove inside the transformer box top cover is connected to the groove in the first water storage square tube, a base is fixedly connected to the bottom end of the first water storage square tube, and a closing component for closing the ventilation fan window is arranged on one side of the first water storage square tube;

The waterproof performance of the wind power transformer is improved, the intrusion of rainwater into the interior of the transformer is reduced, and the service life of the electrical components is increased, thereby ensuring the normal operation of the wind power transformer in extreme weather with heavy precipitation such as heavy rain.

The maximum length from one end of the water outlet to the top of the first water-holding square tube is greater than the minimum length from the curved tube surface to the top of the first water-holding square tube. This avoids rainwater accumulation in the water trough, which causes the transformer box top cover to be subjected to more gravity and causes the transformer box top cover to be aggravated in wear. This improves drainage efficiency and extends the life of the equipment.

[0014] Preferably, a first slide groove is provided on the surface of the slide groove rod, a second slide groove is provided on one side of the first slide groove, the sliding rod is slidably connected to the outer wall of the first slide groove, and the limit rod is slidably connected to the outer wall of the second slide groove; this avoids the problem that the rain shield film is blown by the wind, causing the rain shield film to flutter and affecting the rain shielding ability of the rain shield film, thereby improving the waterproof performance of the wind power transformer and effectively covering and protecting the transformer from rain.

[0015] Preferably, the diameter of the inner groove of the first water-containing square tube is larger than the diameter of the water-containing tank, so that the rainwater in the water-containing tank gives the piston a greater thrust, thereby improving the reliability of the device.

[0017] Preferably, a button is provided above the slide bar, and the button is provided on the surface of the top cover of the transformer box; while the vents are blocked, a rainproof film is lowered to prevent rainwater from invading the interior of the transformer through the gaps between the doors. This double protection greatly improves the waterproof performance of the transformer in extreme weather.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention provides a closing component. When the wind power transformer is in extreme weather with heavy rainfall such as heavy rain, rainwater flows into the first water-containing square tube. Then, by using the communicating vessel principle, rainwater flows into the second water-containing square tube to push the piston and the sliding rod to move upward. The sliding rod drives the first rack to move upward through the linkage block and the connecting rod. During the movement of the first rack, the gear and the rain shield are driven to rotate upward through meshing to block the vent. At the same time, the movement of the first rack drives the linkage rod to move, and the movement of the linkage rod drives the second rack to move. The second rack drives the rain shield on the other side to rotate and block the vent. This avoids the problem that although the traditional wind power transformer has certain waterproof performance, its waterproof ability may be affected to a certain extent in extreme weather such as heavy rain or continuous heavy rainfall, resulting in rainwater invading the interior of the transformer, causing short circuit and rust of electrical components, and affecting the performance of the wind power transformer. The waterproof performance of the wind power transformer is improved, the intrusion of rainwater into the interior of the transformer is reduced, and the service life of the electrical components is increased, thereby ensuring the normal operation of the wind power transformer in extreme weather with heavy rainfall such as heavy rain.

[0020] 2. Through the rain shield component, when the wind power transformer is in extreme weather with heavy precipitation such as heavy rain, rainwater flows into the second water-containing square tube to push the piston and the slide rod to move upward, the slide rod presses the button, the button controls the motor to energize, the output shaft of the motor rotates to drive the drum to rotate, the rotation of the drum causes the rain shield film to rotate and extend, the slide rod slides downward in the first slide groove by gravity and pulls the rain shield film, the motor stops after rotating a set number of circles, and the slide rod reaches the lowest point, preventing rainwater from invading the transformer through the gap between the doors. Impurities and conductive substances in the water may adhere to the surface of the insulating material, forming a conductive path over a long period of time, resulting in a decrease in insulation resistance, thereby reducing the insulation performance of the transformer, which may cause safety hazards when subsequent staff open the door to maintain or overhaul the equipment, thereby improving the waterproof performance of the wind power transformer and ensuring the insulation performance of the equipment and the safety of the staff.

[0021] 3. Through the set bend pipe, when the wind power transformer is in extreme weather with heavy precipitation such as heavy rain, when rainwater flows into the first water-holding square pipe, the height of the rainwater does not exceed the bend of the bend pipe, and the rainwater in the first water-holding square pipe will not flow out. When the height of the rainwater exceeds the bend of the bend pipe, the rainwater flows in from one end of the bend pipe under the siphon effect, and flows out from the bend pipe, and flows until the liquid level is lower than the end of the bend pipe farther from the ground. This avoids the problem that the rainwater in the first water-holding square pipe flows in and out at the same time when the sliding rod is not pushed, that is, the sliding rod does not drive the gear and the rain shield to rotate and the vent is blocked, thereby slowing down the startup of the closing component and affecting the waterproof ability of the device. The reliability of the device is improved, and the rainwater first flows in to start the closing component and then flows out, which speeds up the startup of the closing component and improves the waterproof performance of the wind power transformer.

[0033] Example 1

[0035] The closing component includes a second water-containing square tube 6 fixedly connected to one side of the first water-containing square tube 4, a water tank 10 is opened inside the second water-containing square tube 6, a connecting port 5 is opened on the surface of one side of the first water-containing square tube 4, the tank inside the first water-containing square tube 4 is connected with the water tank 10 inside the second water-containing square tube 6 through the connecting port 5, the outer wall of the water tank 10 is slidably connected with a piston 7, the top of the piston 7 is fixedly connected with a sliding rod 8, the outer wall of the sliding rod 8 is slidably connected with a limiting block 9, the top of the limiting block 9 is provided with a linkage block 31, the linkage block 31 is fixedly connected to the outer wall of the sliding rod 8, one side of the linkage block 31 is fixedly connected with a connecting rod 11, one side of the connecting rod 11 is fixedly connected with a first rack 12, and one side of the first rack 12 is provided with a ventilation component.

[0036] In this embodiment: by setting the closing component, when the wind power transformer is in extreme weather with heavy precipitation such as heavy rain, rainwater flows into the first water-containing square tube 4, and then by using the connecting vessel principle, rainwater flows into the second water-containing square tube 6 to push the piston 7 and the slide bar 8 to move upward, and the slide bar 8 drives the first rack 12 to move upward through the linkage block 31 and the connecting rod 11. During the movement of the first rack 12, the gear 13 and the rain shield 14 are driven to rotate upward through meshing to block the vent. At the same time, the movement of the first rack 12 drives the linkage rod 15 to move, and the movement of the linkage rod 15 drives the second rack 16 The second rack 16 drives the rain shield 14 on the other side to rotate and blocks the vent, thereby avoiding the problem that although the traditional wind power transformer has a certain waterproof performance, its waterproof ability may be affected to a certain extent in extreme weather such as heavy rain or continuous heavy rainfall, resulting in rainwater intruding into the transformer, causing short circuit and rust of electrical components, and affecting the performance of the wind power transformer. The waterproof performance of the wind power transformer is improved, and the rainwater intrusion into the interior of the transformer is reduced, thereby increasing the service life of the electrical components and ensuring the normal operation of the wind power transformer in extreme weather with heavy precipitation such as heavy rain.

[0037] See also Figure 3 and Figure 4 In the figure, the ventilation assembly includes a connecting rod 15 fixedly connected to one side of the first rack 12, one side of the connecting rod 15 is fixedly connected to the second rack 16, the second rack 16 and the first rack 12 are evenly meshed and connected with a gear 13 on one side close to the wind power transformer body 1, one end of the gear 13 is fixedly connected to a rain shield 14, and a rain shield assembly is provided on one side of the first water holding square tube 4.

[0038] In this embodiment: through the ventilation assembly, when the wind power transformer is in extreme weather with heavy precipitation such as heavy rain, the first rack 12 moves upward to drive the rain shield 14 to rotate, and the first rack 12 then drives the second rack 16 to move through the connecting rod 15, and the second rack 16 drives the rain shield 14 on the other side to rotate, blocking the vents on both sides. The simultaneous operation on both sides helps to quickly protect the inside of the transformer in emergency situations such as heavy rain.

[0039] Working principle: Wind power transformers are in extreme weather with heavy precipitation such as heavy rain;

[0040] Rainwater slides down from the top cover 2 of the transformer box and falls into the water receiving grooves 3 on both sides, and then flows into the water flow groove 18 from the two water receiving grooves 3 through the water inlet grooves 17. The rainwater entering from the water receiving groove 3 on the side away from the rain shielding film 24 flows to the side close to the rain shielding film 24 through the inclined water flow groove 18, forming a rainwater intersection, and flows into the first water holding square pipe 4. The first water holding square pipe 4 and the second water holding square pipe 6 form a communicating vessel through the connecting port 5, so that the water surface heights of the rainwater in the first water holding square pipe 4 and the second water holding square pipe 6 are the same. As the rainwater flows in, the rainwater in the second water holding square pipe 6 pushes the piston 7 to move upward, and the piston 7 pushes the slide bar 8 to move upward, the slide bar 8 drives the linkage block 31 to move upward, the linkage block 31 drives the connecting rod 11 to move upward, the connecting rod 11 drives the first rack 12 to move upward, and the first rack 12 drives the gear 13 to rotate through meshing during the upward movement, the rotation of the gear 13 drives the rain shield 14 to rotate upward, one end of the lower rain shield 14 rotates with one end of the upper rain shield 14 to block the vent, the movement of the first rack 12 drives the linkage rod 15 to move, the movement of the linkage rod 15 drives the second rack 16 to move, and similarly the second rack 16 drives the rain shield 14 on the other side to rotate and block the vent.

[0041] When the slide bar 8 moves upward, the button 19 is pressed, and the button 19 controls the motor 20 to be energized. The output shaft of the motor 20 rotates to drive the roller 23 to rotate. The rotation of the roller 23 causes the rain shield film 24 to rotate and extend. The slide bar 25 slides downward in the first slide groove 27 by gravity and pulls the rain shield film 24. The motor 20 stops after rotating a set number of times, and the slide bar 25 reaches the lowest point. The rain shield film 24 prevents rainwater from entering the interior of the wind power transformer body 1 through the gap between the doors.

[0042] When rainwater flows into the first water-containing square tube 4, if the height of the rainwater does not exceed the bend of the curved tube 29, the rainwater in the first water-containing square tube 4 will not flow out. When the height of the rainwater exceeds the bend of the curved tube 29, the rainwater flows in from one end of the curved tube 29 under the siphon effect, and flows out from the curved tube 29 until the liquid level is lower than the end of the curved tube 29 farther from the ground.

[0043] When the rainstorm stops, rainwater in the first water-containing square tube 4 flows out from the curved tube 29, and the water levels in the first water-containing square tube 4 and the second water-containing square tube 6 drop. Similarly, the piston 7 drives the sliding rod 8 to move downward, the sliding rod 8 drives the linking block 31 to move downward, the linking block 31 drives the connecting rod 11 to move downward, the connecting rod 11 drives the first rack 12 to move downward, and in the process of the first rack 12 moving downward, it drives the gear 13 to rotate through meshing, and the rotation of the gear 13 drives the rain shield 14 to rotate downward to reopen the vent, the movement of the first rack 12 drives the linking rod 15 to move, the movement of the linking rod 15 drives the second rack 16 to move, and the second rack 16 drives the rain shield 14 on the other side to rotate, and reopens the vent on the other side.

[0044] When the slide bar 8 moves downward, the button 19 is released. The button 19 controls the motor 20 to be energized. The output shaft of the motor 20 rotates to drive the roller 23 to rotate in the opposite direction. The rotation of the roller 23 causes the rain shield film 24 to rotate and retract. The rain shield film 24 pulls the slide bar 25 upward, causing the slide bar 25 to slide upward in the first slide groove 27. The motor 20 stops after rotating a set number of times, and the roller 23 retracts the rain shield film 24.

[0045] Example 2

[0046] See also Figure 4 and Figure 5 The present embodiment further explains Example 1. The rain shield assembly in the figure includes a slide rod 22 arranged on one side of the first water storing square tube 4. The top of the slide rod 22 is fixedly connected to a fixed block 21. The inner wall of the fixed block 21 is fixedly connected to a motor 20. The outer wall of the output shaft of the motor 20 is fixedly connected to a roller 23. The outer wall of the roller 23 is provided with a rain shield film 24. The surface of the lower end of the rain shield film 24 is fixedly connected to a sliding rod 25. Both ends of the sliding rod 25 are fixedly connected to limit rods 26.

[0047] In this embodiment: through the rain shield component, when the wind power transformer is in extreme weather with heavy rainfall such as heavy rain, rainwater flows into the second water-containing square tube 6 to push the piston 7 and the slide rod 8 to move upward, the slide rod 8 presses the button 19, and the button 19 controls the motor 20 to be energized. The output shaft of the motor 20 rotates to drive the roller 23 to rotate, and the rotation of the roller 23 causes the rain shield film 24 to rotate and extend. The slide rod 25 slides downward in the first slide groove 27 by gravity and pulls the rain shield film 24. The motor 20 stops after rotating a set number of circles, and the slide rod 25 reaches the lowest point, preventing rainwater from invading the transformer through the gap between the doors. Impurities and conductive substances in the water may adhere to the surface of the insulating material. Over time, a conductive path is formed, resulting in a decrease in insulation resistance, thereby reducing the insulation performance of the transformer, which may cause safety hazards when subsequent staff open the door to maintain or overhaul the equipment. The waterproof performance of the wind power transformer is improved, and the insulation performance of the equipment and the safety of the staff are guaranteed.

[0048] See also Figure 5 and Figure 8 In the figure, the inner wall of the bottom end of the first water-containing square tube 4 is fixedly connected with a curved pipe 29, one end of the curved pipe 29 passes through the base 32 and extends to the bottom end of the base 32, and the distance from the other end of the curved pipe 29 to the top of the base 32 is smaller than the distance from the top of the connecting port 5 to the top of the base 32.

[0049] In this embodiment: by setting the curved pipe 29, when the wind power transformer is in extreme weather with heavy precipitation such as heavy rain, when rainwater flows into the first water-containing square pipe 4, the height of the rainwater does not exceed the bend of the curved pipe 29, and the rainwater in the first water-containing square pipe 4 will not flow out. When the height of the rainwater exceeds the bend of the curved pipe 29, the rainwater flows in from one end of the curved pipe 29 under the siphon effect, and flows out from the curved pipe 29 until the liquid level is lower than the end of the curved pipe 29 farther from the ground. This avoids the problem that the rainwater in the first water-containing square pipe 4 flows in and out at the same time when the sliding rod 8 is not pushed, that is, the sliding rod 8 does not drive the gear 13 and the rain shield 14 to rotate and the vent is blocked, thereby slowing down the startup of the closing component and further affecting the waterproof ability of the device. This improves the reliability of the device, first flows in to start the closing component, and then flows out, which speeds up the startup of the closing component and improves the waterproof performance of the wind power transformer.

[0050] See also Figure 2 , the cross section of the water flow trough 18 in the figure is set as an inclined surface; when the wind power transformer is in extreme weather with heavy precipitation such as heavy rain, when the closing component blocks the vent, rainwater slides down from the top cover 2 of the transformer box and falls into the water receiving grooves 3 on both sides, and then flows into the water flow trough 18 through the water inlet groove 17 from the two water receiving grooves 3 respectively. The rainwater entering from the water receiving groove 3 on the side away from the rain shield film 24 flows to the side close to the rain shield film 24 through the inclined setting of the water flow trough 18, forming a rainwater intersection, and flows into the first water holding square tube 4, and uses the rainwater flowing in the water flow trough 18 to dissipate heat, thereby reducing the internal temperature increase caused by the blockage of the vent.

[0051] See also Figure 3 and Figure 6 In the figure, a water outlet 30 is provided on the side of the first water-containing square tube 4 away from the wind power transformer body 1. The water outlet 30 is provided at the top part of the first water-containing square tube 4. The maximum length from one end of the water outlet 30 to the top of the first water-containing square tube 4 is greater than the minimum length from the surface of the bend 29 to the top of the first water-containing square tube 4.

[0052] In this embodiment: by setting the curved pipe 29, when the wind power transformer is in extreme weather with heavy precipitation such as heavy rain, when the height of the rainwater exceeds the bend of the curved pipe 29, the rainwater flows in from one end of the curved pipe 29 due to the siphon effect. When the outflow is less than the inflow, the rainwater will flow out from the water outlet 30, avoiding the accumulation of rainwater in the water trough 18. The transformer box top cover 2 is subjected to more gravity, causing the problem of increased wear of the transformer box top cover 2, thereby improving the drainage efficiency and extending the life of the equipment.

[0053] Example 3

[0054] See also Figure 4 and Figure 7In the figure, a first slide groove 27 is provided on the surface of the slide groove rod 22, a second slide groove 28 is provided on one side of the first slide groove 27, the sliding rod 25 is slidably connected to the outer wall of the first slide groove 27, and the limiting rod 26 is slidably connected to the outer wall of the second slide groove 28.

[0055] In the present embodiment: by setting the first slide groove 27, when the wind power transformer is in extreme weather with heavy rainfall such as heavy rain, rainwater flows into the second water-containing square tube 6 to push the piston 7 and the slide rod 8 to move upward, the output shaft of the motor 20 rotates to drive the roller 23 to rotate, and the rotation of the roller 23 causes the rain shield film 24 to rotate and extend, and the sliding rod 25 slides downward in the first slide groove 27 by gravity and pulls the rain shield film 24. When the sliding rod 25 slides to the lowest point, the wind is prevented from blowing the rain shield film 24, causing the rain shield film 24 to flutter and affecting the rain shielding ability of the rain shield film 24, thereby improving the waterproof performance of the wind power transformer, and effectively covering and protecting the transformer from rain.

[0056] See also Figure 5 and Figure 8 In the figure, the diameter of the internal groove of the first water-containing square tube 4 is larger than the diameter of the water-containing tank 10; when the wind power transformer is in extreme weather with heavy rainfall such as heavy rain, when the rainwater in the first water-containing square tube 4 flows into the water-containing tank 10 in the second water-containing square tube 6 through the connecting port 5, the first water-containing square tube 4 and the second water-containing square tube 6 form a communicating vessel through the connecting port 5, so that the rainwater in the water-containing tank 10 gives the piston 7 a greater thrust, thereby improving the reliability of the device.

[0057] See also Figure 6 and Fig. 9 In the figure, the cross section of the rain shield 14 is set to be "Z"-shaped, the lengths of the two sides of the rain shield 14 are equal, and the maximum length of the upper and lower ends of the rain shield 14 is equal to twice the minimum length of the upper and lower ends of the rain shield 14.

[0058] In the present embodiment, by providing the rain shield 14, when the wind power transformer is in extreme weather with heavy precipitation such as heavy rain, the gear 13 rotates to drive the rain shield 14 to rotate upward. Since one end of the lower rain shield 14 can be fully engaged with one end of the upper rain shield 14 during the rotation process, a tight sealing structure is formed, which effectively blocks the intrusion of rainwater and improves the waterproof performance of the wind power transformer.

[0059] See also Figure 3 and Figure 6 In the figure, a button 19 is arranged above the slide bar 8, and the button 19 is arranged on the surface of the transformer box top cover 2. The input end of the button 19 is connected to the output end of the power supply inside the wind power transformer body 1; the output end of the button 19 is connected to the input end of the motor 20, and the model of the motor 20 is YS7124.

[0060] In this embodiment: by setting the button 19, when the wind power transformer is in extreme weather with heavy rainfall such as heavy rain, when the piston 7 pushes the slide bar 8 to move upward, the slide bar 8 presses the button 19 during the upward movement, and the button 19 controls the motor 20 to energize and lower the rain shield film 24. While blocking the vents, the rain shield film 24 is lowered to prevent rainwater from invading the inside of the transformer through the gap between the doors. This double protection greatly improves the waterproof performance of the transformer in extreme weather.
