Description

Technical Field

[0001] This utility model relates to the field of oil-immersed transformer technology, specifically a novel oil-immersed transformer. Background Technology

[0002] Oil-immersed transformers are a common type of transformer in which the internal windings and core are immersed in insulating oil. This oil is usually mineral oil or silicone oil, which has good insulation properties and cooling effect. Oil-immersed transformers are commonly used in industrial and power systems, and their advantages include stability and reliability, good insulation performance, high temperature resistance, and long service life.

[0003] As disclosed in the patent announcement CN215299029U, a novel oil-immersed transformer includes a transformer housing. One outer surface of the transformer housing is equipped with an oil tank storage mechanism. A wiring port is located on one side of the upper end of the transformer housing, and an oil level gauge is installed on one side of the wiring port. The beneficial effects of this invention are: the oil tank storage mechanism allows for the opening of the sealing cover and the extraction of mineral oil from the storage tank when the oil level inside the transformer housing drops, facilitating timely replenishment of mineral oil by maintenance personnel.

[0004] The above-mentioned device has a simple structure and reasonable design, which can meet the needs of users and has great promotional value;

[0005] While the aforementioned patent allows workers to easily add insulating oil manually, workers cannot add it continuously. When the oil level in an oil-immersed transformer drops, workers need to receive a maintenance notification and go to the designated location to manually add the oil, which takes a lot of time and results in low maintenance efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a novel oil-immersed transformer to solve the problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A new type of oil-immersed transformer, including

[0009] The oil-immersed transformer body has an oil tank vertically installed on one side of its exterior, and a replenishment tank is fixedly installed on one side of the top of the oil tank via a mounting bracket.

[0010] An oil replenishment port is provided through the middle of the oil storage tank and the oil replenishment tank. A pressure rod is movably sleeved inside the oil replenishment port, and a first float is fixedly installed at the bottom end of the pressure rod.

[0011] A sealing disc is provided at the lower end of the pressure rod near the oil replenishment port, and the diameter of the sealing disc is larger than the diameter of the oil replenishment port.

[0012] Preferably, a first spring is provided at the upper end of the oil tank near the oil filling port, a baffle is fixedly installed on the top of the pressure rod, and the other end of the first spring is located below the baffle.

[0013] Preferably, a rectangular strip is provided through the top center of the oil tank, a second float is fixedly installed at the bottom end of the rectangular strip, a rack is fixedly installed at the top end of the rectangular strip, a dial is fixedly installed on the side of the oil tank near the rack via a mounting base, a connector is movably installed on the front center of the dial via a rotating shaft, a pointer is provided on the side of the connector away from the rack, and a gear ring is provided on the front side of the connector, the gear ring meshing with the rack;

[0014] Preferably, a second spring is fixedly installed on both sides of the top of the second floating roof, and the other ends of the two second springs are located on both sides of the upper part of the inside of the oil tank;

[0015] Preferably, an oil outlet is provided on one side of the bottom of the oil tank, and the oil outlet is connected to the interior of the oil-immersed transformer body;

[0016] Preferably, the volume of the oil storage tank is five times that of the replenishment tank.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This novel oil-immersed transformer utilizes a combination of an oil storage tank, a replenishment tank, a replenishment port, a pressure rod, a first floating plate, and a sealing plate. When the sealing plate descends, the replenishment port opens, allowing insulating oil from the replenishment tank to automatically flow through the port into the storage tank. As oil from the replenishment tank enters the storage tank, the oil level rises. At this point, the first floating plate controls the sealing plate to rise synchronously and reseal the replenishment port. This allows for real-time replenishment when oil is insufficient, eliminating the need for manual intervention and improving replenishment efficiency.

[0019] 2. This novel oil-immersed transformer utilizes a combination of a replenishing tank, rectangular bars, a second floating disc, a rack, a gear ring, a dial, and a pointer. When oil from the replenishing tank is added to the storage tank, the second floating disc descends synchronously with the drop in liquid level. This, in turn, causes the rack to descend via the rectangular bars. As the rack descends, it controls the rotation of the gear ring. The rotation of the gear ring, through a connector, causes the pointer on one side to swing, thus allowing the remaining amount of insulating oil in the replenishing tank to be known from outside the equipment.

[0026] 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.

[0027] like Figure 1-5 As shown, this utility model provides a technical solution:

[0028] A novel oil-immersed transformer includes an oil-immersed transformer body 1. An oil storage tank 2 is vertically arranged on one side of the oil-immersed transformer body 1. A replenishment tank 4 is fixedly installed on one side of the top of the oil storage tank 2 via a mounting bracket 3. A replenishment port 5 is provided through the middle of the oil storage tank 2 and the replenishment tank 4. A pressure rod 6 is movably sleeved inside the replenishment port 5. A first floating plate 7 is fixedly installed at the bottom end of the pressure rod 6. A sealing plate 8 is provided at the lower end of the pressure rod 6 near the replenishment port 5. The diameter of the sealing plate 8 is larger than the diameter of the replenishment port 5. The volume of the oil storage tank 2 is five times that of the replenishment tank 4. An oil outlet 20 is provided on one side of the bottom of the oil storage tank 2. The oil outlet 20 is connected to the interior of the oil-immersed transformer body 1.

[0029] In this embodiment, when the insulating oil level inside the oil storage tank 2 is insufficient, the first float 7 will descend synchronously with the decrease of insulating oil. When the first float 7 descends, it drives the sealing plate 8 to descend synchronously through the pressure rod 6. When the sealing plate 8 descends, the oil replenishment port 5 opens. At this time, the insulating oil inside the oil replenishment tank 4 automatically passes through the oil replenishment port 5 and enters the oil storage tank 2 to replenish the oil. As the oil in the oil replenishment tank 4 enters the oil storage tank 2, the liquid level rises accordingly. At this time, the first float 7 controls the sealing plate 8 to rise synchronously and seal the oil replenishment port 5 again. In this way, when there is a shortage of oil, it can be replenished in real time without waiting for manual handling by workers, which can improve the oil replenishment efficiency.

[0030] like Figure 2 and Figure 5 As shown, a rectangular bar 11 is provided through the middle of the top of the oil tank 4. A second float 12 is fixedly installed at the bottom of the rectangular bar 11. A rack 13 is fixedly installed at the top of the rectangular bar 11. A dial 15 is fixedly installed on the side of the oil tank 4 near the rack 13 via a mounting base 14. A connector 16 is movably installed on the center of the front of the dial 15 via a rotating shaft. A pointer 17 is provided on the side of the connector 16 away from the rack 13. A gear ring 18 is provided on the front side of the connector 16, and the gear ring 18 meshes with the rack 13.

[0031] In this embodiment, when the oil in the replenishment tank 4 is replenished into the oil storage tank 2, the second floating plate 12 descends synchronously as the liquid level drops, and then drives the rack 13 to descend through the rectangular bar 11. When the rack 13 descends, it controls the toothed ring 18 to rotate. After the toothed ring 18 rotates, it drives the pointer 17 on one side to swing through the connector 16. In this way, the remaining amount of insulating oil in the replenishment tank 4 can be known from the outside of the equipment.

[0032] like Figure 3 and Figure 4 As shown, a second spring 19 is fixedly installed on both sides of the top of the second floating plate 12, and the other ends of the two second springs 19 are located on both sides of the upper part of the inside of the oil tank 4; a first spring 9 is provided on the upper part of the oil tank 4 near the oil filling port 5, and a baffle 10 is fixedly installed on the outside of the top of the pressure rod 6, and the other end of the first spring 9 is located below the baffle 10.

[0033] In this embodiment, the first spring 9 and the second spring 19 have the same function. When the liquid level in the oil storage tank 2 drops, the first spring 9 rebounds to control the first floating plate 7 to drop synchronously. When the liquid level in the replenishment tank 4 drops, the second spring 19 controls the second floating plate 12 to drop synchronously. In this way, when the liquid level of the insulating oil decreases, it can react quickly.

[0034] Working principle: When the insulating oil level inside the oil storage tank 2 is insufficient, the first float 7 will descend synchronously with the decrease of insulating oil. When the first float 7 descends, it drives the sealing plate 8 to descend synchronously through the pressure rod 6. When the sealing plate 8 descends, the oil replenishment port 5 opens. At this time, the insulating oil inside the oil replenishment tank 4 automatically enters the oil storage tank 2 through the oil replenishment port 5 to replenish the oil. As the oil in the oil replenishment tank 4 enters the oil storage tank 2, the liquid level rises accordingly. At this time, the first float 7 controls the sealing plate 8 to rise synchronously and seal the oil replenishment port 5 again. After the oil inside the oil replenishment tank 4 is replenished into the oil storage tank 2, the second float 12 descends synchronously with the decrease of liquid level, and then drives the rack 13 to descend through the rectangular bar 11. When the rack 13 descends, it controls the gear ring 18 to rotate. After the gear ring 18 rotates, it drives the pointer 17 on one side to swing through the connector 16.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
