Abstract
Description
Technical Field

[0002] A search revealed that existing ovens used for producing high-voltage reactors with series resonant withstand voltage devices mostly place the high-voltage reactors directly on the inner drawer panel of the oven without any securing measures. During the drying process, equipment vibration can easily cause the reactors to collide with the inner wall of the cavity, resulting in surface damage or displacement of the internal windings, affecting the electrical performance of the product. At the same time, the reactors may tilt or shift due to gravity or airflow impact during hot air circulation, leading to uneven heating and affecting the consistency of the curing of the insulation material. Therefore, an oven for producing high-voltage reactors with series resonant withstand voltage devices is provided to solve the above problems. Utility Model Content

[0022] Reference Figures 1 to 4 In this embodiment of the present invention, a drying oven for producing high-voltage reactors of a series resonant withstand voltage device includes: a drying oven 1, which is used to load the high-voltage reactors of the series resonant withstand voltage device that need to be dried;
[0023] The reactor fixing mechanism 2 stably clamps the high-voltage reactor placed therein, preventing the impact of vibration on the high-voltage reactor during drying.
[0024] The drying oven 1 includes a main shell 11, a drying chamber 12 is provided on the inner side of the main shell 11, and a rotating door 13 is provided on the outer side of the main shell 11. The main shell 11 adopts a composite structure of metal frame and heat insulation layer. The rotating door 13 can be opened and closed 180° through a hinge shaft. The high temperature resistant sealing strip on the edge of the door frame is tightly attached to the main shell 11 in the closed state to form a uniform heat insulation interface.
[0025] The reactor fixing mechanism 2 includes a lower fixing plate 21, which is fixedly connected to the inside of the drying chamber 12 via both sides of the lower fixing plate 21. A sliding drawer plate 22 is slidably connected above the lower fixing plate 21. Four sets of long guide rods 23 are fixedly connected above the lower fixing plate 21. An upper moving plate 24 is provided above the lower fixing plate 21. Four sets of guide holes adapted to the long guide rods 23 are opened above the upper moving plate 24. Connecting arms 25 are rotatably connected to the middle of both sides of the upper moving plate 24. One end of the connecting arm 25 is rotatably connected to the middle of both sides of the upper moving plate 24. The other end of 5 is rotatably connected to both sides of the sliding drawer plate 22. A fixed pressure plate 26 is provided below the upper moving plate 24. Four sets of short guide rods 27 are fixedly connected above the fixed pressure plate 26. A support spring 28 is sleeved on the outside of the short guide rods 27. The two ends of the support spring 28 are fixedly connected to the lower part of the upper moving plate 24 and the upper part of the fixed pressure plate 26, respectively. Four sets of guide through holes adapted to the short guide rods 27 are opened below the upper moving plate 24. A threaded through hole 29 extending to the bottom of the lower fixed plate 21 is opened above the lower fixed plate 21. A hand-tightening screw 210 is threadedly connected to the inside of the threaded through hole 29.
[0026] The sliding drawer plate 22 slides along the lower fixed plate 21 to realize the loading and positioning of the reactor. When the sliding drawer plate 22 is loaded and retracted, it will drive the upper moving plate 24 to press down along the long guide rod 23 through the connecting arm 25. The elastic clamping system composed of the short guide rod 27 and the support spring 28 makes the fixed pressure plate 26 adaptively ballast the surface of the reactor. After the hand screw 210 is screwed into the threaded through hole 29, it forms a mechanical stop to prevent the sliding drawer plate 22 from being accidentally displaced under vibration conditions.
[0027] The working principle of this utility model is as follows: the operator places the high voltage reactor on the sliding drawer plate 22. At this time, the sliding drawer plate 22 is fully extended, which facilitates the stable placement and position adjustment of the reactor. After placement, the sliding drawer plate 22 containing the reactor is pushed into the drying chamber 12 along the slide rail of the lower fixed plate 21 to the set position.
[0028] When the sliding drawer plate 22 retracts inward, the connecting arm 25 moves in conjunction with the displacement of the sliding drawer plate 22, driving the upper moving plate 24 to move vertically downward along the four sets of long guide rods 23. During the downward pressing of the upper moving plate 24, the short guide rod 27 guides the fixed pressure plate 26 to move downward synchronously. The support spring 28 is compressed to generate uniform elastic force, so that the fixed pressure plate 26 adaptively fits the reactor surface, forming a vertical elastic clamping force to avoid rigid contact that could damage the device.
[0029] After the clamping is completed, the operator rotates the hand screw 210 so that it is screwed into the threaded through hole 29 of the lower fixed plate 21. The end of the screw abuts against the bottom surface of the sliding drawer plate 22, forming a horizontal mechanical limit, locking the axial position of the sliding drawer plate 22, preventing it from sliding, and ensuring a stable elastic clamping force on the high voltage reactor.
[0030] After the rotating door 13 is closed, the heat insulation layer of the main housing 11 and the sealing strip cooperate to form a closed drying chamber 12. The drying box 1 delivers hot air into the drying chamber 12. At the same time, the elastic clamping force of the reactor fixing mechanism 2 continuously compensates for thermal expansion deformation and vibration caused by drying, maintaining clamping stability.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
