Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and in particular to a three-electrode smelting transformer. Background Technology

[0002] Three-electrode smelting transformers are mainly used for power supply and control in the smelting process. They can convert the input electrical energy into high current and low voltage to supply power to industrial electric arc furnaces, so as to generate a strong electric arc between the electrodes, thereby heating and melting the metal. Smelting transformers are also called electric arc furnace transformers in the metallurgical industry, and are a special type of transformer.

[0003] As described in announcement number CN219832365U, a transformer heat dissipation structure includes a transformer protective enclosure, a transparent enclosed door, a transformer fixing and mounting assembly, and a transformer heat dissipation assembly. The transformer fixing and mounting assembly includes shock-absorbing and anti-collision pads, a clamping plate groove, a clamping plate slider, a movable clamping plate, a rotating threaded rod, and a rotating handle. The transformer heat dissipation assembly includes a cold water box fixing seat, a cold water storage box, a cold water suction pump, a cold water circulation and delivery pipe, a connecting frame shock absorber, a ring plate connecting frame, a heat dissipation support ring plate, a motor support shaft, a wind-cooled heat dissipation motor, a rotating heat dissipation transmission shaft, rotating heat dissipation fan blades, and a heat dissipation ventilation mesh plate. The transformer fixing and mounting assembly facilitates the fixing and installation of the transformer, and allows for a combination of wind-cooling and water-cooling heat dissipation, resulting in good heat dissipation and protection.

[0004] This patent combines air cooling and water cooling to dissipate heat from the transformer. However, existing transformers do not have dustproof features when dissipating heat. Over time, the surface of the transformer will accumulate a lot of dust, which not only affects the cleanliness of the radiator but also affects heat dissipation, thus reducing the heat dissipation effect.

[0005] Therefore, we propose a novel three-electrode smelting transformer. Utility Model Content

[0006] The purpose of this invention is to solve the problem that existing transformers do not have a dustproof function when dissipating heat. Over a long period of use, the surface of the transformer will accumulate a lot of dust, which not only affects the cleanliness of the radiator but also affects heat dissipation, thus reducing the heat dissipation effect.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a three-electrode smelting transformer, comprising a housing, a transformer body disposed inside the housing, dustproof and heat dissipation components connected to both sides of the housing, the dustproof and heat dissipation components comprising a connecting frame connected to one outer surface of the housing, a temperature-controlled fan connected to the inside of the housing near the connecting frame, a dustproof mesh disposed inside the connecting frame, slots provided on both sides of the dustproof mesh, magnetic insertion rods inserted into the slots, a fixing frame connected to the other side of the housing, a movable plate disposed inside the fixing frame, a threaded hole provided at the bottom of the movable plate, a servo motor connected to the bottom of one side of the fixing frame, a one-way screw connected to the output end of the servo motor, and heat dissipation holes provided on the other side of the housing.

[0008] Furthermore, the outer surfaces of both sides of the dustproof net are in contact with the inner walls of both sides of the connecting frame, and a sliding connection is formed between the dustproof net and the connecting frame.

[0009] Furthermore, both the temperature-controlled fan and the servo motor are electrically connected to an external power source via a controller, and the output end of the servo motor is fixedly connected to the unidirectional screw.

[0010] Furthermore, the movable plate is threadedly connected to the one-way screw via a threaded hole, and the movable plate is slidably connected to the fixed frame.

[0011] Furthermore, a protective assembly is connected to the top of the outer shell, the protective assembly including four sets of fixing blocks, which are respectively connected to the four corners of the top of the outer shell.

[0012] Furthermore, a spring is provided inside the fixing block, and a connecting rod is connected to the top of the spring. Protective plates are fixedly connected to the tops of the four sets of connecting rods.

[0013] Furthermore, the bottom outer surface of the connecting rod is in contact with the inner wall of the fixing block, and the connecting rod and the spring form an elastic structure.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, when the transformer body operates for a long time and high temperature occurs, the temperature control fan will automatically turn on to dissipate heat from the transformer body. Then, the servo motor, under the action of the controller, will drive the one-way screw to rotate, thereby moving the moving plate through the screw rotation. This allows the slot of the moving plate to be aligned with the heat dissipation hole, enabling the heat dissipation hole to work with the temperature control fan for heat dissipation. After use, the moving plate will reset to seal the heat dissipation hole. This not only dissipates heat from the transformer body but also prevents dust, improving the cleanliness and service life of the transformer body.

[0016] 2. In this utility model, when the transformer body is in use, if a falling object occurs at the top, the transformer body can be protected by a protective plate. Under the elastic force of the spring, the impact force of the falling object can also be reduced, avoiding the problem that falling objects can easily damage the transformer body, thus improving the protective performance of the transformer body.

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1, such as Figure 1 - Figure 5 As shown, this utility model provides a three-electrode smelting transformer, including a housing 1. A transformer body 5 is disposed inside the housing 1. Dustproof and heat dissipation components 2 are connected to both sides of the housing 1. The dustproof and heat dissipation components 2 include a connecting frame 201, which is connected to one outer surface of the housing 1. A temperature-controlled fan 202 is connected to the inside of the housing 1 near the connecting frame 201. A dustproof mesh 203 is disposed inside the connecting frame 201. Slots 204 are provided on both sides of the dustproof mesh 203, and magnetic insertion rods 205 are inserted into the slots 204. A fixing frame 206 is connected to the other side of the housing 1. A movable plate 207 is disposed inside the fixing frame 206, and the bottom of the movable plate 207 is open... The mounting bracket 206 has a threaded hole and a servo motor 209 is connected to one side of the bottom. The output end of the servo motor 209 is connected to a one-way screw 208. The other side of the housing 1 has a heat dissipation hole 210. The outer surfaces of the dustproof net 203 are in contact with the inner walls of the connecting bracket 201. The dustproof net 203 and the connecting bracket 201 are slidably connected. The temperature control fan 202 and the servo motor 209 are both electrically connected to an external power supply through a controller. The output end of the servo motor 209 is fixedly connected to the one-way screw 208. The moving plate 207 is threadedly connected to the one-way screw 208 through a threaded hole. The moving plate 207 and the mounting bracket 206 are slidably connected.

[0027] The overall effect of Embodiment 1 is that, under prolonged use, the interior of the transformer body 5 will experience high temperatures. The temperature-controlled fan 202 will then automatically activate to dissipate heat from the transformer body 5. The installed dust filter 203 provides dust protection. Simultaneously, the controller activates the reverse rotation function of the servo motor 209. When the output of the servo motor 209 rotates in reverse, it also drives the one-way screw 208 to reverse. When the one-way screw 208 reverses, it rotates in the opposite direction through the threaded hole with the moving plate 207, allowing the moving plate 207 to move within the fixed frame 206 via this threaded rotation. This ensures that the slot of the moving plate 207 is aligned with the heat dissipation hole 210. Combined with the temperature-controlled fan 202, this effectively dissipates heat from the transformer body 5. The high-temperature air inside the shell 1 is discharged, thus achieving a heat dissipation effect. When the internal temperature of the shell 1 drops, the temperature control fan 202 will automatically turn off. At this time, the controller will turn on the forward rotation function of the temperature control fan 202, so that the moving plate 207 can move in the reverse direction within the fixed bracket 206, thereby sealing the heat dissipation hole 210 to prevent dust from entering the shell 1 and adhering to the surface of the transformer body 5. It can be pulled out from the slot 204 by pulling the magnetic plug 205 to both sides. Then the dust filter 203 can be removed for dust cleaning. The magnetic connection method can improve the convenience of disassembling and assembling the dust filter 203 and achieve the sealing of the heat dissipation hole 210. This not only achieves heat dissipation of the transformer body 5, but also has a dust prevention effect, improving the cleanliness and service life of the transformer body 5.

[0028] Example 2, as Figure 1 and Figure 6 As shown, a protective component 3 is connected to the top of the outer shell 1. The protective component 3 includes four sets of fixing blocks 301. The four sets of fixing blocks 301 are respectively connected to the four corners of the top of the outer shell 1. A spring 302 is provided inside the fixing block 301. A connecting rod 303 is connected to the top of the spring 302. A protective plate 304 is fixedly connected to the top of the four sets of connecting rods 303. The bottom outer surface of the connecting rod 303 is in contact with the inner wall of the fixing block 301. An elastic structure is formed between the connecting rod 303 and the spring 302.

[0029] The effect achieved by the entire embodiment 2 is that when a falling object occurs on the top of the transformer body 5, the transformer body 5 can be protected by the protective plate 304. After being impacted, the protective plate 304 will be squeezed against the spring 302. Under the elastic force of the spring 302, the impact force of the falling object can be reduced, avoiding the problem that falling objects can easily damage the transformer body 5, and improving the protection of the transformer body 5.

[0030] Working principle: When the transformer body 5 operates for a long time and reaches a high temperature, the temperature control fan 202 will automatically turn on to dissipate heat from the transformer body 5. Then, the servo motor 209, under the control of the controller, will drive the one-way screw 208 to rotate, thereby moving the moving plate 207 through the screw rotation. This allows the slot of the moving plate 207 to be aligned with the heat dissipation hole 210, enabling the heat dissipation hole 210 to work with the temperature control fan 202 for heat dissipation. After use, the moving plate 207 will reset to seal the heat dissipation hole 210. This not only dissipates heat from the transformer body 5 but also prevents dust, improving the cleanliness and service life of the transformer body 5. In the event of falling objects from above the transformer body 5 during use, the protective plate 304 can protect the transformer body 5. The elastic force of the spring 302 can also reduce the impact of falling objects, preventing damage to the transformer body 5 from falling objects and improving the protection of the transformer body 5.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
