Abstract
Description
Technical Field
[0001] This utility model relates to the field of transformer technology, and in particular to a vibration damping device for transformers and a transformer. Background Technology
[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current (AC) voltage. Its main components include a primary coil, a secondary coil, and an iron core. When AC current is applied to the primary coil, an alternating magnetic field is generated in the iron core. This alternating magnetic field induces an electromotive force (EMF) in the secondary coil. According to the law of electromagnetic induction, the EMF induced in the secondary coil is related to the number of turns in the primary coil, the number of turns in the secondary coil, and the voltage across the primary coil. By changing the turns ratio of the primary and secondary coils, the voltage can be increased or decreased. Transformers generate vibration during operation, requiring vibration damping devices during installation for protection.
[0003] To this end, patent CN221960791U discloses a vibration damping device for a dry-type transformer, which includes a base; a mounting plate fixedly mounted on the top of the base; a support plate disposed on the top of the mounting plate; a dry-type transformer, the bottom of which slides in contact with the top of the support plate; multiple mounting rods; a positioning mechanism and a control mechanism, the positioning mechanism being two sets, which respectively cooperate with the mounting plate and the control mechanism. The positioning mechanism is used to position the mounting rods, and the control mechanism is used to unlock the mounting rods. In this utility model, by placing the dry-type transformer on the support plate and then installing multiple mounting rods, the mounting rods can install the dry-type transformer, and the damper and shock-absorbing springs can dampen the vibration of the dry-type transformer, reducing the noise generated by the dry-type transformer.
[0004] The existing technical solutions mentioned above have the following drawbacks: Although the transformer can be damped by the combination of dampers and shock-absorbing springs, the damping method is relatively simple and it is inconvenient to stabilize the transformer. As a result, it cannot adapt to the location of the transformer's vibration source after installation, and thus cannot effectively absorb and offset the vibration generated during the operation of the transformer. Utility Model Content
[0005] The purpose of this utility model is to provide a vibration damping device and a transformer for transformers, so as to solve the defects of existing vibration damping devices and transformers that are inconvenient to stabilize and dampen the transformer.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a vibration damping device for a transformer and a transformer, including a transformer body;
[0007] A base plate is fixedly connected to the bottom of the transformer body, and a vibration damping mechanism is installed at the bottom of the base plate.
[0008] The vibration damping mechanism includes a support plate fixedly installed at the bottom of the base plate. A first rotating shaft is installed at the bottom of the support plate. A support plate is movably connected to the outer wall of the first rotating shaft. A second rotating shaft is movably connected to the inside of the support plate. A movable block is movably connected to the outer wall of the second rotating shaft. A damping spring is fixedly connected to one side of the movable block.
[0009] Preferably, the movable block has a guide groove inside, a positioning plate is movably connected to the outer wall of the movable block, and a guide plate is fixedly connected to the inner wall of the positioning plate.
[0010] Preferably, the receiving plate forms a rotating structure with the support plate via a first rotating shaft, and the support plate forms a rotating structure with the movable block via a second rotating shaft, which allows the support plate to rotate along the receiving plate.
[0011] Preferably, the movable block forms a sliding structure with the guide plate via a guide groove, and the guide plate is symmetrically arranged about the central axis of the positioning plate, so that the movable block can slide along the guide plate.
[0012] Preferably, an auxiliary buffer mechanism is fixedly connected to the bottom of the positioning plate. The auxiliary buffer mechanism includes a mounting plate fixedly installed at the bottom of the positioning plate, a guide rod fixedly connected to the top of the mounting plate, a buffer spring fixedly connected to the top of the mounting plate, a buffer spring piece movably connected to the outer wall of the guide rod, and an avoidance groove provided inside the buffer spring piece.
[0013] Preferably, the guide rod and the base plate form a sliding structure, the base plate has an open design, the base plate is arranged parallel to the mounting plate, and the buffer spring is sleeved on the outer wall of the guide rod, which can provide auxiliary vibration reduction for the transformer body.
[0014] Preferably, the buffer spring is movably connected to the guide rod through a clearance groove, and the buffer spring is arc-shaped, which can provide auxiliary buffering for the transformer body.
[0015] The advantages of the vibration damping device and transformer provided by this utility model are as follows:
[0016] By setting up a transformer body, base plate, and vibration damping mechanism, the transformer body generates vibration during operation, causing the base plate to press against the support plate. This allows the support plate to rotate and press against the movable block, which in turn presses against the damping spring, thus facilitating vibration damping and protection of the transformer body.
[0017] Furthermore, with the combined action of the guide groove and the guide plate, the stability of the sliding of the movable block can be improved, so that the movable block only applies horizontal compressive force to the damping spring, thereby further improving the stability of the transformer body vibration reduction and protection.
[0018] Furthermore, since the positioning plate is equipped with two damping springs inside and the positioning plate is symmetrically arranged with respect to the central axis of the base plate, the stability of the transformer body vibration reduction can be further improved, and the damping springs can effectively absorb the vibration generated at different positions of the transformer body.
[0019] By using the transformer body, base plate, and auxiliary buffer mechanism, the base plate vibrates and slides along the guide rod. Under the action of the buffer spring, it is easy to perform auxiliary vibration reduction on the transformer body.
[0020] Furthermore, with the combined action of the buffer spring and the guide rod, the buffer spring can absorb some of the vibration transmitted by the base plate, and the buffer spring can provide auxiliary support and vibration reduction for the base plate, thereby further improving the stability of the transformer body for vibration reduction and protection.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figures 1-5 The present invention provides a transformer vibration damping device and a transformer, including a transformer body 1.
[0029] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a base plate 2 is fixedly connected to the bottom of the transformer body 1. A vibration damping mechanism 3 is installed at the bottom of the base plate 2. The vibration damping mechanism 3 includes a support plate 31 fixedly installed at the bottom of the base plate 2. A first rotating shaft 32 is installed at the bottom of the support plate 31. A support plate 33 is movably connected to the outer wall of the first rotating shaft 32. A second rotating shaft 34 is movably connected to the inside of the support plate 33. A movable block 35 is movably connected to the outer wall of the second rotating shaft 34. A damping spring 37 is fixedly connected to one side of the movable block 35. A guide groove 36 is opened inside the movable block 35. A positioning plate 38 is movably connected to the outer wall of the movable block 35. A guide plate 39 is fixedly connected to the inner wall of the positioning plate 38. The support plate 31 and the support plate 33 form a rotating structure through the first rotating shaft 32. The support plate 33 and the movable block 35 form a rotating structure through the second rotating shaft 34. The movable block 35 and the guide plate 39 form a sliding structure through the guide groove 36. The guide plate 39 is symmetrically arranged about the central axis of the positioning plate 38.
[0030] The vibration generated by the operation of the transformer body 1 can be transmitted to the receiving plate 31 through the base plate 2, causing the receiving plate 31 to press against the support plate 33. Since the support plate 33 forms a rotating structure with the receiving plate 31 through the first rotating shaft 32, and the support plate 33 forms a rotating structure with the movable block 35 through the second rotating shaft 34, the support plate 33 can rotate and press against the movable block 35, causing the movable block 35 to slide along the positioning plate 38, so that the movable block 35 presses against the damping spring 37, thereby providing vibration reduction and protection for the transformer body 1.
[0031] Reference Figure 1 , Figure 2 and Figure 3As shown, an auxiliary buffer mechanism 4 is fixedly connected to the bottom of the positioning plate 38. The auxiliary buffer mechanism 4 includes a mounting plate 41 fixedly installed at the bottom of the positioning plate 38, a guide rod 42 fixedly connected to the top of the mounting plate 41, a buffer spring 43 fixedly connected to the top of the mounting plate 41, a buffer spring 44 movably connected to the outer wall of the guide rod 42, and an avoidance groove 45 opened inside the buffer spring 44. The guide rod 42 and the base plate 2 form a sliding structure. The base plate 2 is designed with an open hole. The base plate 2 and the mounting plate 41 are arranged parallel to each other. The buffer spring 43 is sleeved on the outer wall of the guide rod 42. The buffer spring 44 is movably connected to the guide rod 42 through the avoidance groove 45. The buffer spring 44 is arc-shaped.
[0032] Vibration of the base plate 2 causes it to slide along the guide rod 42, which in turn causes the buffer spring 44 to compress the buffer spring 43, thus reducing vibration of the base plate 2. As the buffer spring 44 slides down along the guide rod 42, when it comes into contact with and is compressed by the mounting plate 41, it will deform, causing the guide rod 42 to slide along the clearance groove 45, thus providing auxiliary support and vibration reduction for the base plate 2.
