Description

Technical Field

[0001] This utility model relates to the field of oil-immersed transformer technology, specifically to an oil-immersed transformer with an oil storage mechanism. Background Technology

[0002] Oil-immersed transformers are crucial equipment in power supply and distribution systems for industrial and mining enterprises and civil buildings. The transformer is filled with transformer oil, and the transformer and other equipment are immersed in it. Because transformer oil has high insulation and drainage properties, oil-immersed transformers effectively improve the insulation of transformers and other equipment, while also preventing fires and other disasters. A search revealed existing public technology publication number CN111968835A, which describes an oil-immersed transformer with an oil storage mechanism, including a shell, an oil tank, and a boss. The shell has a rectangular structure with a connecting seat mounted on one wide side. The connecting seat has two sets of support rods. The oil tank is mounted on top of the support rod. The oil tank has a cylindrical structure and an oil supply pipe at the top. The oil tank is connected to the shell through the oil supply pipe. An exhaust valve is installed on one end of the oil tank symmetrical to the oil supply pipe. A cuboid boss is welded to the side of the oil tank facing the shell. A pressure gauge is installed on the boss. A drying box is located next to the pressure gauge. The boss has a slot, and the drying box is threadedly connected to the boss through the slot. A sealing plate is provided inside the boss, and multiple sets of vent holes are opened on the sealing plate. This oil-immersed transformer with an oil storage mechanism effectively reduces the contact area between transformer oil and air, thus improving the service life of the transformer.

[0003] In summary, although the above cases solved the oil storage problem, the lack of buffering and shock absorption for oil-immersed transformers makes them susceptible to damage when subjected to external vibrations and impacts. Furthermore, in the cases mentioned above, outdoor oil-immersed transformers are easily damaged by hail during hailstorms, leading to malfunctions. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing an oil-immersed transformer with an oil storage mechanism. This addresses the issue that while the oil storage problem is solved in the aforementioned cases mentioned in the background art, the lack of buffering and shock absorption for the oil-immersed transformer makes it prone to damage when subjected to external vibrations and impacts. Furthermore, in the aforementioned cases, outdoor oil-immersed transformers are easily damaged by hail during hailstorms, leading to malfunctions.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oil-immersed transformer with an oil storage mechanism, comprising a transformer structure, wherein a buffer and shock-absorbing structure is installed below the transformer structure;

[0006] The transformer structure includes an oil-immersed transformer body as the main body, and a locking block with a slot is fixed on one side of the oil-immersed transformer body, while a threaded plate with a connecting block is fixed at the bottom of the oil-immersed transformer body.

[0007] The threaded plate is connected to a rotating nut that is threadedly connected to the buffer and shock-absorbing structural components.

[0008] By adopting the above technical solution, the threaded plate is used to achieve threaded installation connection.

[0009] Preferably, the card block is engaged with the protective plate via a card slot, and the protective plate has a through hole for easy wire extension.

[0010] By adopting the above technical solution, the set card blocks can achieve a locking and fixing connection.

[0011] Preferably, the buffer and shock absorption structure encloses a base plate with a connecting frame welded to its bottom, and one end of the damping shock absorber is fixedly connected to the base plate, while the other end of the damping shock absorber is fixedly connected to the bottom of the bearing plate.

[0012] By adopting the above technical solution, the damping shock absorber can achieve buffering and shock absorption.

[0013] Preferably, connecting plates are symmetrically fixed on the base plate, and sliding rods are fixed between the connecting plates. A connecting spring is provided through the sliding rod, and one end of the connecting spring is fixedly connected to one side of the connecting plate.

[0014] By adopting the above technical solution, the connecting plate is used to achieve a fixed installation connection.

[0015] Preferably, the other end of the connecting spring is fixedly connected to the through-hole recess, and the through-hole recess slides and adjusts with the slide rod. At the same time, the through-hole recess is rotatably connected to one end of the double-hole connecting plate through a connecting pin. The other end of the double-hole connecting plate is also installed and connected to the bottom of the bearing plate through a connecting pin and another through-hole recess.

[0016] By adopting the above technical solution, the connecting spring is used to achieve a through-hole fixed connection between the two ends.

[0017] Preferably, the bearing plate has a threaded hole and a sliding groove for limiting the sliding movement of the connecting block.

[0018] By adopting the above technical solution, the supporting plate is set up to achieve opening and fixed installation.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the oil-immersed transformer with an oil storage mechanism,

[0020] (1) This case solves the problem that outdoor oil-immersed transformers are easily hit by hail when hail occurs in the above case by setting up a transformer structure, which can cause them to fail to operate normally. When it rains or hails, the rain and hail fall on the protective plate to shield the top of the oil-immersed transformer. When the protective plate shields the top of the oil-immersed transformer, it avoids the hail from causing collision damage to the top of the oil-immersed transformer.

[0021] (2) By setting up a buffer and shock absorption structure, the problem of damage to the oil-immersed transformer is solved because the oil-immersed transformer cannot be buffered and shock absorbed. When the oil-immersed transformer body is subjected to external vibration and impact, the oil-immersed transformer body will transmit the vibration to the bearing plate. At this time, the bearing plate will be squeezed by the damping shock absorber and the through hole concave block. When the through hole concave block is squeezed, it will be squeezed by the connecting spring. Through the force movement of the connecting spring and the damping shock absorber, the oil-immersed transformer body will be buffered and shock absorbed.

[0022] (3) By setting up a sliding groove, connecting block, threaded hole and rotating nut, the problem of the existing oil-immersed transformer body being unable to be quickly removed for maintenance after installation is solved. When the oil-immersed transformer body needs to be removed for maintenance, the operator can loosen the rotating nut and push the oil-immersed transformer body to drive the connecting block and the sliding groove to slide relative to each other, thus facilitating the quick removal of the oil-immersed transformer body.

[0028] 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.

[0029] Please see Figure 1-4 This utility model provides a technical solution: an oil-immersed transformer with an oil storage mechanism, such as... Figure 1 , Figure 2 and Figure 3 As shown, the transformer structure 1 includes an oil-immersed transformer body 101 as the main body, and a locking block 102 with a locking groove 103 is fixed on one side of the oil-immersed transformer body 101. At the same time, a threaded plate 104 with a connecting block 105 is fixed at the bottom of the oil-immersed transformer body 101.

[0030] Furthermore, the threaded plate 104 is connected to a rotating nut 106 that is threaded to the components of the buffer and shock absorption structure 2. There are four rotating nuts 106, which improve the connection and fixation between the threaded plate 104 and the bearing plate 204.

[0031] Furthermore, in the above scheme, the card block 102 is engaged with the protective plate 107 through the card slot 103, and the protective plate 107 is provided with a through hole 108 to facilitate the extension of the wire. The protective plate 107 is made of high polymer flame retardant material. Using high polymer flame retardant material to set the protective plate 107 not only improves the service life of the protective plate 107, but also avoids the protective plate 107 being damaged by fire.

[0032] In the above scheme, when rain or hail falls, the rain and hail fall on the protective plate 107 and provide shielding protection for the oil-immersed transformer body 101.

[0033] like Figure 4 As shown, a buffer and shock-absorbing structure 2 is installed below the transformer structure 1. The buffer and shock-absorbing structure 2 covers the base plate 201, to which the connecting frame 202 is welded and fixed. One end of the base plate 201 is fixedly connected to the damping shock absorber 203, while the other end of the damping shock absorber 203 is fixedly connected to the bottom of the bearing plate 204.

[0034] Furthermore, in the above scheme, connecting plates 205 are symmetrically fixed on the base plate 201, and sliding rods 206 are fixed between the connecting plates 205. At the same time, a connecting spring 207 is provided through the sliding rod 206, and one end of the connecting spring 207 is fixedly connected to one side of the connecting plate 205.

[0035] Furthermore, in the above scheme, the other end of the connecting spring 207 is fixedly connected to the through-hole recess 208, and the through-hole recess 208 slides and adjusts with the slide rod 206. At the same time, the through-hole recess 208 is rotatably connected to one end of the double-hole connecting plate 209 through a connecting pin. The other end of the double-hole connecting plate 209 is also connected to the bottom of the bearing plate 204 through a connecting pin and another through-hole recess 208. The above components constitute a compression sliding elastic adjustment structure. When the compression sliding elastic adjustment structure constituted by the above components is used, the connecting spring 207 and the damping shock absorber 203 are driven to adjust synchronously by force.

[0036] Furthermore, the above scheme has a threaded hole 2010 on the bearing plate 204 and a sliding groove 2011 on the bearing plate 204 to limit the sliding movement of the connecting block 105.

[0037] In the above scheme, when the oil-immersed transformer body 101 is subjected to vibration, the vibration is transmitted to the bearing plate 204. At this time, the bearing plate 204 exerts pressure on the damping shock absorber 203 and the through hole recess 208. When the through hole recess 208 is subjected to pressure, it exerts pressure on the connecting spring 207. Through the force movement of the connecting spring 207 and the damping shock absorber 203, the oil-immersed transformer body 101 is buffered and damped. When the oil-immersed transformer body 101 needs to be removed for maintenance, the operator loosens the rotating nut 106 and pushes the oil-immersed transformer body 101 to drive the connecting block 105 and the slide groove 2011 to slide relative to each other under force, thus facilitating the quick removal of the oil-immersed transformer body 101.
