Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and in particular, to an energy-saving air-cooled power transformer. Background Art

[0002] A power transformer is a static electrical device used to convert an alternating voltage of a certain value into another or several different values of alternating voltages with the same frequency. It is a static device with two or more windings. In order to transmit electrical energy, at the same frequency, through electromagnetic induction, the alternating voltage and current of one system are converted into the voltage and current of another system. Usually, the values of these currents and voltages are different. Transformers can be classified into power transformers, test transformers, instrument transformers, and transformers for special purposes according to their uses.

[0003] When an energy-saving air-cooled power transformer is used outdoors, it is usually equipped with a protective shell and a temperature control system. The temperature control system usually consists of a cooling fan, a PLC controller, and a temperature detector. The temperature control system can monitor the temperature inside the protective shell. When the transformer overheats, the cooling fan will be automatically started to dissipate heat from the transformer, avoiding the situation that the energy-saving air-cooled power transformer is damaged due to overheating in high-temperature weather, and it will only dissipate heat when the temperature of the transformer is too high, which can reduce unnecessary energy consumption and save energy.

[0004] An existing energy-saving air-cooled power transformer is internally equipped with an electric track and a brush roller. By starting the electric track, the brush roller can be driven to move. The brush roller can clean the dust screen on the inner side of the transformer housing, reducing the occurrence of dust screen blockage. However, the bristles of the brush roller are easily adsorbed and contaminated with dust during the cleaning process, and the long-term accumulation of dust on the bristles of the brush roller will reduce the cleaning effect of the brush roller on the dust screen. Summary of the Invention

[0006] To achieve the above object, the present invention provides the following technical solution: An energy-saving air-cooled power transformer, comprising a protective frame, a transformer body, heat dissipation plates, heat dissipation fans, a cleaning structure, a transmission structure, a mounting structure and a fixed seat. The transformer body is fixedly arranged at the central position inside the protective frame. The heat dissipation plates are arranged inside the protective frame, and there are two groups of heat dissipation plates. And the two groups of heat dissipation plates are respectively attached to both sides of the transformer body. The heat dissipation fans are fixedly arranged on the side opposite to the heat dissipation plates and the transformer body. The cleaning structure is arranged inside the protective frame.

[0020] Preferably, four groups of knocking rods are provided, and rubber pads are provided at one ends of the four groups of knocking rods facing the dust-proof net.

[0021] By adopting the above technical solution, the rubber pad is provided to buffer the impact force when the knocking rod collides with the dust-proof net, avoiding the damage of the dust-proof net during the slight knocking process.

[0022] Preferably, a third limiting rod is fixedly arranged inside the vibration frame, and the third limiting rod is slidably connected with the limiting block, and the third limiting rod passes through the hole formed at the center of the third spring.

[0043] Embodiment III

[0044] Please refer specifically to Figures 1 - 10, the knocking structure 8 is arranged inside the protective frame 1 and on one side of the dust-proof net 707. The knocking structure 8 has a cross bar 801 fixedly arranged on the outer wall of the slider of the electric slide rail 501.

Under the action of the third spring 807, the guide wheel 804 can be closely attached to the wavy protrusion of the guide frame 805 during vertical movement. When the guide wheel 804 moves vertically, it can move horizontally under the influence of the wavy protrusion. The horizontal movement of the guide wheel 804 will drive the knocking rod 803 to move horizontally back and forth. The reciprocating horizontal movement of the knocking rod 803 can knock on the dust-proof net 707, and the dust on the surface of the dust-proof net 707 will be loosened under the influence of vibration, thereby improving the cleaning effect of the brush roller 502.

[0045] Working principle: When the temperature inside the protective frame 1 is too high, the temperature monitoring component will start the cooling fan 4, the exhaust fan, and the electric slide rail 501. The cooling fan 4 and the exhaust fan work to dissipate heat from the transformer body 2 inside the protective frame 1. When the electric slide rail 501 works, it will drive the brush roller 502 to move vertically. The vertical movement of the brush roller 502 cleans the dust on the surface of the dust-proof net 707, reducing the occurrence of blockage of the dust-proof net 707. During the operation of the electric slide rail 501, it will drive the cross bar 801 vertically. The vertical movement of the cross bar 801 will drive the vibration frame 802 to move. The vertical movement of the vibration frame 802 will drive the knocking rod 803 to move vertically. The movement of the knocking rod 803 will drive the guide wheel 804 to move;

[0046] Secondly, since the guide wheel 804 fits with the wavy protrusions inside the guide frame 805, the knocking rod 803 will move horizontally under the cooperation of the guide wheel 804 and the wavy protrusions. The movement of the knocking rod 803 will drive the limit block 806 to move. The movement of the limit block 806 will cause the third spring 807 to deform. When the guide wheel 804 separates from the protruding part of the wavy protrusion, the third spring 807 will recover its deformation and drive the knocking rod 803 to move, so that the knocking rod 803 can move horizontally back and forth. The reciprocating movement of the knocking rod 803 slightly knocks on the dust-proof net 707, causing the dust-proof net 707 to vibrate to a certain extent, and the dust on the surface of the dust-proof net 707 will become loose, thereby improving the cleaning effect of the brush roller 502;

[0047] Then, when the electric slide rail 501 works, it will drive the sliding plate 601 to move. The movement of the sliding plate 601 will drive the sliding block 602 to move vertically. The vertical movement of the sliding block 602 will drive the connecting block 609 to move. The movement of the connecting block 609 will drive the roller 610 to move. Since the roller 610 is inserted into the arc groove 702, the roller 610 will slide in the arc groove 702 under the downward force of the connecting block 609. The sliding of the roller 610 will drive the connecting block 609 to move horizontally. The horizontal movement of the connecting block 609 drives the sliding block 602 to move horizontally. Since the sliding block 602 is hinged to the connecting rod 608 and the connecting rod 608 is hinged to the transmission frame 604, the horizontal movement of the sliding block 602 will drive the transmission frame 604 to rotate. The rotation of the transmission frame 604 will drive the scraper 606 to rotate. During the rotation of the scraper 606, the first spring 605 will gradually recover its deformation and push the scraper 606 to move. During the rotation of the scraper 606, it always fits with the brush roller 502. The scraper 606 will rotate to the upper side of the brush roller 502. When the brush roller 502 moves downward, it will rotate counterclockwise under the influence of friction. The scraper 606 will clean the surface of the brush roller 502;

[0048] Finally, when the brush roller 502 drives the roller 610 to move to the bottom position of the arc groove 702, the roller 610 will drive the connecting block 609 to move horizontally. The movement of the connecting block 609 can drive the squeegee 606 to rotate. The squeegee 606 will be perpendicular to the brush roller 502. When the brush roller 502 rotates clockwise upward, the squeegee 606 will rotate again and move to the bottom position of the brush roller 502. The surface of the brush roller 502 is cleaned by the squeegee 606 to ensure the cleaning effect of the brush roller 502.

[0049] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and practical concept of the present invention, making equivalent replacements or changes should be covered within the protection scope of the present invention.
