Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of transformers, in particular to a low-noise transformer with active condensation removal. BACKGROUND

[0002] Dry-type transformers are widely used in indoor and semi-outdoor environments (such as power distribution rooms and subway tunnels) due to their advantages such as no need for insulating oil, good fire resistance, high operating efficiency, small size, and low noise. However, the epoxy resin casting or impregnation process of the insulation system is extremely sensitive to humidity.

[0003] In humid environments, such as the persistent rainy weather in the middle and lower reaches of the Yangtze River, the humidity inside the transformer box increases due to ventilation and heat dissipation, and the water vapor condenses on the transformer when the air humidity inside the box is greater than 60%. When the temperature suddenly changes (such as at night), the water vapor condenses on the surface of the core / winding. The presence of liquid water on the surface of insulating materials such as epoxy resin and insulating paper significantly reduces their dielectric strength, and long-term use can cause cracking and loss of barrier function. The absorption of liquid water on the core reduces the heat dissipation capacity of the core, further exacerbating the temperature rise, and the magnetic domain movement of the silicon steel sheet is more active, with a 1.8-fold increase in the nonlinear coefficient of magnetostriction, leading to a 30% increase in the amplitude of the 100Hz fundamental frequency vibration.

[0004] Magnetostriction is the periodic expansion and contraction of silicon steel under alternating magnetic fields (with a frequency twice that of the power frequency), which causes the core to vibrate and produce a low-frequency humming noise (usually above 50dB), causing noise interference in quiet environments such as hospitals and office buildings. Long-term vibration can cause wear and tear on the winding insulation, cracking of the epoxy resin, or loosening of the fasteners, leading to partial discharge, short circuit, and other faults. The vibration process consumes electrical energy and converts it into heat energy, exacerbating the temperature rise and reducing the efficiency of the transformer. Magnetostriction is temperature-sensitive: at high temperatures, the magnetic domain activity of the silicon steel sheet is more active, the magnetostriction coefficient increases, and the vibration amplitude increases, resulting in a significant increase in noise.

[0005] Therefore, in order to prevent the expansion of the amplitude of magnetostriction caused by a humid environment, thereby preventing noise and damage to the transformer, the present application proposes a low-noise transformer with active condensation removal, aiming to improve the ability to remove condensation on the surface of the transformer.

When the vibration of the iron core 2 is abnormal, the vibration amplitude of the iron core 2 increases, and the moving distance of the vibration disc 62 increases. The vibration disc 62 drives the passive member 65 to move.

[0047] The shaft of the ratchet wheel 67 in the one-way transmission assembly is an output shaft of the conversion assembly 6, the pawl 66 in the one-way transmission assembly is made of a flexible material, so that the energy transmission is smooth, the one-way transmission assembly can convert the longitudinal displacement generated by the vibration into the rotation of the ratchet wheel 67 through the pawl 66, and the shaft of the ratchet wheel 67 outputs externally; the one-way transmission assembly can also include a magnetic fluid sealing cavity, which is automatically activated when the rotation force transmission is interrupted.

[0048] It should be noted that when the vibration amplitude of the iron core 2 increases, the vibration disc 62 drives the passive rings 651, the passive frame 652 and the pawl 66 to move up and down, so as to drive the ratchet wheel 67 to rotate and output the rotary force externally.

[0049] The moving assembly 7 is arranged on one side of the conversion assembly 6 and connected with the air channel 4, and can store the rotating force output by the conversion assembly 6 and further inhibit the abnormal vibration of the iron core 2.

[0050] The moving assembly 7 comprises a lead screw 71 connected with the output shaft of the conversion assembly 6, and a moving piece 72 arranged on the lead screw 71 and capable of moving thereon, and a piston 74 arranged on the side of the moving piece 72 away from the conversion assembly 6, and an energy storage tank 73 arranged outside the piston 74 and matched with the piston 74.

[0051] The lead screw 71 is rotationally connected with the air channel 4, and fixedly connected with the shaft of the ratchet wheel 67 and synchronously rotated with the ratchet wheel 67, and can drive the moving piece 72 to move along the length direction of the lead screw 71, so as to push the piston 74 to move in the energy storage tank 73; the energy storage tank 73 is fixedly connected with the air channel 4, and filled with nitrogen medium, and the pressure is maintained at 0.3-0.5 MPa.

[0052] The moving piece 72 is internally provided with a movable block 721 slidably connected therewith, the movable block 721 is capable of threadedly cooperating with the lead screw 71, and the movable block 721 is provided with a third elastic piece 722 at the end away from the lead screw 71, the third elastic piece 722 is connected with the movable block 721 at one end and connected with the inside of the moving piece 72 at the other end.

[0053] The moving piece 72 is provided with a driving wheel 723 and a driven wheel 724 on one side, the driving wheel 723 and the driven wheel 724 are rotationally connected with the moving piece 72, the driving wheel 723 is sleeved outside the lead screw 71, the driving wheel 723 and the driven wheel 724 are meshed with each other, the driven wheel 724 is a gear with partial teeth, and the driven wheel 724 is eccentrically provided with a push column 725 on the side close to the movable block 721, the push column 725 can limit the position of the movable block 721, the push column 725 is in contact with the movable block 721 and can push the movable block 721 to move according to the rotation angle of the driven wheel 724.

[0054] The driving wheel 723 is in contact with the lead screw 71, when the lead screw 71 rotates, the driving wheel 723 can be driven by the lead screw 71, so that the driving wheel 723 can rotate with the lead screw 71, when the lead screw 71 stops rotating, the driving wheel 723 will be reversely driven by the driven wheel 724, so that the driven wheel 724 drives the push column 725 to reset; when the lead screw 71 continuously rotates the driving wheel 723, the driven wheel 724 will only rotate a certain angle because it has partial teeth, the movable block 721 will be pushed to the position matched with the lead screw 71 and will not continue to move, so that the movable block 721 is always matched with the lead screw 71 when the lead screw 71 rotates, the moving piece 72 will move with the lead screw 71 as long as the lead screw 71 rotates, when the lead screw 71 stops rotating, the movable block 721 is separated from the lead screw 71, and the moving piece 72 is reset under the action of the energy storage tank 73.

[0055] It should be noted that when the lead screw 71 rotates, the driving wheel 723 drives the driven wheel 724 to rotate, the push column 725 on the driven wheel 724 pushes the movable block 721 to contact and threadedly cooperate with the lead screw 71, so that the lead screw 71 drives the moving part 72 to move; when the lead screw 71 stops rotating, the movable block 721 is pulled by the third elastic member 722 and separated from the lead screw 71, and at the same time pushes the push column 725 to rotate the driven wheel 724 to reset, at this time, the movable block 721 has been separated from the lead screw 71, and the moving part 72 moves towards the direction close to the conversion assembly 6 due to the pushing force from the piston 74, and resets.

[0056] When the transformer works normally, the magnetostriction of the iron core 2 causes the whole to be in a normal state, the transmission member 61 transmits the vibration of the iron core 2 to the vibration disc 62, at this time, the vibration disc 62 does not contact the passive member 65 when moving up and down, and the vibration disc 62 is affected by the elastic force of the first elastic member 63 when moving up and down, so as to reduce the vibration amplitude of the iron core 2 through the transmission member 61, suppress the vibration amplitude of the iron core 2, avoid the loosening, falling and noise of the connecting member caused by vibration, and ensure the high stability of the transformer.

[0057] When the design voltage of the transformer does not match the actual voltage, the iron core 2 will cause the whole temperature to uniformly rise and the vibration amplitude to increase due to magnetic flux saturation, at this time, the vibration disc 62 will contact the passive member 65 when moving up and down, and drive the passive member 65 to move up and down, so as to drive the pawl 66 to move up and down, drive the ratchet wheel 67 to rotate, and the passive member 65 will be limited by the elastic force of the second elastic member 68 when moving, so as to suppress the excessive vibration of the iron core 2; the ratchet wheel 67 rotates to drive the lead screw 71 to rotate, the driving wheel 723 on the moving part 72 rotates to drive the driven wheel 724 to rotate, the push column 725 on the driven wheel 724 pushes the movable block 721 to threadedly cooperate with the lead screw 71, so as to drive the moving part 72 to move along the lead screw 71, and drive the piston 74 to move in the energy storage tank 73, the gas pressure in the energy storage tank 73 further suppresses the abnormal vibration of the iron core 2 through the piston 74, the moving part 72, the lead screw 71 and the ratchet wheel 67; when the moving part 72 contacts the sensor 75 during movement, the heat dissipation power of the heat dissipation device 5 is increased, and the transformer is cooled through the air channel 4.

[0058] When the temperature of the transformer core 2 is reduced to the normal level, the vibration of the core 2 due to magnetostriction returns to the normal state, at this time, the up and down movement of the vibration disc 62 is not in contact with the passive element 65, the ratchet wheel 67 stops rotating with the screw rod 71, the movable block 721 is pulled by the third elastic element 722 and has a tendency to be separated from the screw rod 71, the push column 725 on the driven wheel 724 is affected by the movement tendency of the movable block 721, the driven wheel 724 rotates reversely with the driving wheel 723, the push column 725 moves away from the screw rod 71, the movable block 721 has a moving space, thereby being separated from the screw rod 71, and the threaded cooperation between the movable block 721 and the screw rod 71 is released, at this time, the piston 74 is pushed by the pressure in the energy storage tank 73, thereby pushing the moving element 72 to move towards the conversion assembly 6, and the moving element 72 is reset.

[0059] In the embodiment, the vibration of the transformer core 2 in the normal state is suppressed by the first elastic element 63, the vibration suppression ability of the transformer core 2 in the abnormal state is improved by the combined action of the second elastic element 68 and the pressure in the energy storage tank 73, and the heat dissipation power of the heat dissipation device 5 is adjusted in real time according to the movement position of the moving element 72, so that the temperature of the transformer is quickly reduced to the normal level, thereby getting rid of the abnormal state and removing the noise in the abnormal state, and the safety and stability of the transformer are ensured, the above settings strengthen the ability of the transformer to suppress its own vibration, reduce the noise, and improve the stability of the transformer.

[0060] Embodiment Two

[0061] In actual use, when a humid environment is encountered, external moisture will enter the transformer box along with the ventilation of the transformer, and the phenomenon of condensation of condensed water on the surface of the transformer will occur, which will cause the heat dissipation capacity of the core 2 to decrease, the local temperature of the core 2 to rise rapidly, the magnetostriction amplitude of the core 2 to expand, and the vibration of the transformer due to the humid environment to increase.

[0062] To solve the above technical problems, in another embodiment of the present application, the ventilation opening 41 is provided with a blade 42, and the transformer further comprises a driving assembly 8 connected to the other side of the conversion assembly 6, the driving assembly 8 can drive the blade 42 to complete the wind blowing action, and can change the movement state of the blade 42 according to the state of the moving assembly 7.

[0063] The blade 42 in the air channel 4 is provided with a plurality of rotating shafts, and the plurality of blades 42 are connected by a linkage 43, so that the plurality of blades 42 can move synchronously.

[0064] In the embodiment, the driving assembly 8 comprises a driving box 86 connected with the conversion assembly 6, and the driving box 86 is internally provided with a driving bevel gear 81 and a driven bevel gear 82 capable of being engaged with each other, the driving bevel gear 81 is in sliding connection with the output shaft of the conversion assembly 6, the driving bevel gear 81 is provided with a spline, and the output shaft of the conversion assembly 6 is provided with a sliding groove matched with the spline, and the rotating shaft of the driven bevel gear 82 extends out of the driving box 86.

[0065] The spline on the driving bevel gear 81 enables the driving bevel gear 81 to rotate following the output shaft of the conversion assembly 6 and to change the engagement state with the driven bevel gear 82, and the materials of the driving bevel gear 81 and the driven bevel gear 82 are required to be carburized and quenched to have a hardness of HRC 58-62.

[0066] The driving box 86 is externally provided with a connecting rod structure 85, one end of the connecting rod structure 85 is connected with the rotating shaft of the driven bevel gear 82, and the other end is connected with the vane 42, and the connecting rod structure 85 can drive the vane 42 to oscillate according to the rotation of the driven bevel gear 82.

[0067] The connecting rod structure 85 can adopt a Chebyshev connecting rod structure, one node in the connecting rod structure 85 is driven to rotate by the shaft of the driven bevel gear 82, the connecting rod structure 85 forms a node connected with the vane 42 to oscillate at a non-uniform speed, the rod connected with the connecting rod structure 85 is provided with a sliding groove to ensure that the connecting rod structure 85 can drive the vane 42 to complete the oscillation, the connecting rod structure 85 and the vane 42 can enable the vane 42 to complete the one-way rapid oscillation and the reverse slow movement, and the connecting rod structure 85 comprises a temperature difference expansion compensator, and the material thermal expansion coefficient is ≤2×10⁻ 6 / ℃.

[0068] The driving assembly 8 further comprises a pushing piece 83 associated with the driving assembly 8 and the moving assembly 7, when the moving piece 72 is in the initial position, that is, the lead screw 71 does not rotate, the pushing piece 83 is pushed to the position farthest from the energy storage tank 73 by the moving piece 72, at this time, the driving bevel gear 81 and the driven bevel gear 82 are not in the engaged state, even if the ratchet wheel 67 rotates, the connecting rod structure 85 will not drive the vane 42 to move; after the lead screw 71 rotates, the moving piece 72 moves, and the pushing piece 83 moves following the moving piece 72 due to the fourth elastic piece 84, at this time, the driving bevel gear 81 moves following the pushing piece 83 until the driving bevel gear 81 and the driven bevel gear 82 are engaged with each other, the pushing piece 83 is separated from the moving piece 72 and no longer moves following the moving piece 72, at this time, the connecting rod structure 85 drives the vane 42 to move according to the rotation of the driven bevel gear 82.

[0069] The power for driving the movement of the driving assembly 8 is entirely from the vibration of the iron core 2, that is, the driving power for the wind blowing action of the blade 42 is generated by the vibration of the iron core 2, without other power sources, which prevents the magnetic field generated by the power source such as a motor from affecting the magnetic field of the transformer itself during operation, avoids system parallel resonance, causes voltage distortion amplification, and breaks down the insulation.

[0070] It should be noted that when the transformer is normally operating, the vibration amplitude of the iron core 2 is small, which does not cause the movement of the moving assembly 7 and the driving assembly 8; when the transformer is overloaded, the temperature of the iron core 2 rises, the vibration amplitude increases, the moving part 72 of the moving assembly 7 pushes the piston 74 to move, increasing the ability to limit vibration, at the same time, the position sensor in the moving assembly 7 detects the position change of the moving part 72, enhances the power of the heat dissipation device 5, and performs efficient heat dissipation on the iron core 2; when condensate appears on the surface of the iron core 2, the temperature of the iron core 2 rises rapidly, the vibration amplitude of the iron core 2 increases rapidly, the moving part 72 of the moving assembly 7 starts to move, the pusher 83 follows the movement, and the driving assembly 8 can drive the blade 42 to perform the fan blowing action, thereby removing the condensate on the surface of the iron core 2.

[0071] It should be noted that when condensate appears in the transformer, the temperature of the iron core 2 rises rapidly, the vibration amplitude of the iron core 2 increases, the vibration disc 62 contacts the passive part 65 when moving up and down, and drives the passive part 65 to move up and down, thereby driving the pawl 66 to move up and down, driving the ratchet wheel 67 to rotate, the ratchet wheel 67 rotating drives the lead screw 71 to rotate, thereby driving the moving part 72 to move along the lead screw 71, when the moving part 72 moves, the pusher 83 moves along with the moving part 72 due to the elastic force of the fourth elastic member 84, and at the same time, the pusher 83 drives the driving bevel gear 81 to move towards the driven bevel gear 82 until the driven bevel gear 82 and the driving bevel gear 81 complete meshing, the pusher 83 stops moving, and the moving part 72 continues to move, at this time, the output shaft of the conversion assembly 6 drives the driving bevel gear 81 to rotate, so that the driven bevel gear 82 rotates, and the rotation of the driven bevel gear 82 is converted into the fan blowing of the blade 42 through the connecting rod structure 85, when the blade 42 blows, it will perform the action of one-way rapid blowing and reverse slow blowing under the influence of the connecting rod structure 85, strengthening the wind force of the air passage 4 on the iron core 2, thereby strengthening the removal of the water attached to the iron core 2.

[0072] The present application can strengthen the air flow in the transformer by driving the linkage blade 42 through the driving assembly 8, improve the ability of the transformer to remove the water attached to its surface, and the movement of the driving assembly 8 is linked with the moving part 72, so that the movement state of the connecting rod structure 85 is associated with the position of the moving part 72, which improves the response speed of the transformer when removing the condensed water and improves the stability of the transformer in the humid environment. In this state, the movement of the blade 42 is associated with the vibration of the core 2, which strengthens the ability of the transformer to remove the surface condensed water, and solves the problem of the influence of the humid environment on the working state and stability of the transformer.

[0073] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change within the technical range disclosed by the present application according to the technical scheme and the inventive concept of the present application, which should be covered within the protection scope of the present application.
