Description

Technical Field

[0001] This invention relates to the field of transformer technology, and in particular to a dry-type transformer with high-temperature protection function. Background Technology

[0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery and equipment and other places. A dry-type transformer is a transformer whose core and windings are not immersed in insulating oil.

[0003] Existing dry-type transformers primarily utilize the principle of electromagnetic induction to transfer electrical energy or transmit signals from one circuit to another, converting current and voltage in the circuit to reduce energy consumption during transmission. For example, application number CN201910519329.1 discloses a dry-type transformer, including a transformer body, a casing, a base plate, and a fan. The transformer body is composed of multiple sets of encapsulated windings arrayed together, and a support rod is provided at the bottom of the transformer body, connecting each set of encapsulated windings to each other. However, in the above technology, the fan is directly directed at the transformer body for heat dissipation, but the rapid cooling rate can easily damage the transformer body. Therefore, we propose a dry-type transformer with high-temperature protection function to solve the above problems. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a dry-type transformer with high-temperature protection. This high-temperature protection dry-type transformer mainly utilizes a control mechanism installed inside the casing. A built-in temperature sensor detects and tests the temperature of the equipment during operation, transmitting the signal to the control mechanism. A built-in motor outputs power to drive a meshing gear set, which in turn drives a lead screw assembly. This adjusts the size of the opening by changing the position of the adjustment plate and the housing. With the help of the cooling fan in the heat dissipation components, the high-temperature air inside the equipment can be expelled in a timely manner, achieving a gradual cooling effect and avoiding irreversible damage to the transformer mechanism caused by excessively rapid cooling.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-7 In this embodiment of the invention, a dry-type transformer with high-temperature protection function includes a base assembly 1 and a control mechanism 5. A bolt-assembled housing component 2 is provided on the top side of the base assembly 1, and a plug-in connected opening and closing component 3 is provided on one side of the housing component 2. A fitted transformer mechanism 4 is provided on the inner top side of the housing component 2. The control mechanism 5 is provided inside the housing component 2, and a plug-in connected heat dissipation component 6 is provided on the rear side of the housing component 2.

[0030] The base assembly 1 includes a reinforced concrete block 101, a shock-absorbing damper 102, a base plate 103, an insulating column 104, a pad 105, and a buried pipe 106. The shock-absorbing damper 102 is provided on the top side of the reinforced concrete block 101, and the base plate 103 is provided on the top side of the shock-absorbing damper 102. The pad 105 is bolted to the top side of the base plate 103 through the insulating column 104. The buried pipe 106 is sleeved between the pad 105 and the inner side of the base plate 103.

[0031] In an embodiment of the present invention, the steel-concrete block 101 and the shock-absorbing damper 102 are placed in the soil for backfilling, so that the base plate 103 above the shock-absorbing damper 102 is above the soil. Before backfilling, the backfilling pipe 106 is installed through the inner side of the base plate 103 and the pad 105, and the base plate 103 and the pad 105 are bolted together by the insulating column 104. After the installation is completed, the cable is laid through the backfilling pipe 106.

[0032] The housing component 2 includes a bolt base plate 201, a housing 202, a plug groove 203, finned protrusions 204, a side cover 205, a bolt locking plate 206, a top pad 207, a bolt connecting column 208, and a top plate 209. The housing 202 is bolted to the top side of the pad 105 via the bolt base plate 201. The plug groove 203 is provided on the rear side of the housing 202. The finned protrusions 204 are provided on the inner side of the housing 202. The side covers 205 are provided on both sides of the housing 202 and bolted to the bolt locking plate 206.

[0033] In an embodiment of the present invention, after the base assembly 1 is set up, the housing 202 is connected and fixed by using a bolt base plate 201 on the top side of the pad 105, and the heat dissipation component 6 is inserted and fixed by using a plug groove 203 on the rear side of the housing 202. Since the inner side of the housing 202 is provided with finned protrusions 204, the heat generated by the equipment can be quickly absorbed during the use of the equipment.

[0034] A top pad shell 207 is provided on the top side of the outer casing 202, and a top plate 209 is bolted to the top side of the top pad shell 207 via a bolt connecting column 208.

[0035] In the embodiments of the present invention, since the top plate 209 has a trapezoidal structure and a slope angle at one end, it has the effect of blocking light in hot weather, which helps the equipment avoid the rapid temperature rise caused by direct sunlight, and also has the effect of guiding water to avoid rain.

[0036] The opening and closing assembly 3 includes a lead screw compartment 301, a drive lead screw 302, a sliding bar 303, a door panel 304, an insert bar 305, and a control panel 306. The lead screw compartment 301 is located on the outer side of the outer casing 202. The sliding bar 303 is threadedly connected to the lead screw compartment 301 via the drive lead screw 302. A door panel 304 is located on the inner side of one end of the sliding bar 303. The door panel 304 is inserted into the outer casing 202 via the insert bar 305. The control panel 306 is located on the front side of the door panel 304.

[0037] In an embodiment of the present invention, when the equipment needs maintenance, the side cover 205 connected by bolts and the bolt locking plate 206 are disassembled. Then, the drive screw 302 on the screw compartment 301 is started to output power to drive the output end of the drive screw 302 to run. This causes the output end of the drive screw 302 to drive the sliding strip 303 to push the door panel 304 out of the outer casing 202, allowing the insert strip 305 to leave the outer casing 202, so as to facilitate the user to perform maintenance on the equipment. Since the front side of the door panel 304 is provided with a control panel 306, it can display the operating status of the equipment to reflect the working process of the equipment.

[0038] The transformer mechanism 4 includes an insulating pad 401, a transformer body 402, a plug-in connector 403, a threaded base 404, a plug-in nut 405, a safety plug plate 406, a top cylinder 407, a side socket 408, and a connecting pipe 409. The insulating pad 401 is located on the inner top side of the housing 202. The transformer body 402 is located above the insulating pad 401. The plug-in connector 403 is located on the top side of the transformer body 402. The output end of the plug-in nut 405 is connected to the threaded base 404 through the top of the plug-in connector 403.

[0039] In an embodiment of the present invention, during use, a passage is formed by inserting the safety plug 406 between the threaded base 404 and the side socket 408, and then by adjusting the plug nut 405, the plug 403 provided below the threaded base 404 is inserted into the transformer body 402 provided above the insulating pad 401 to form a closed passage, thereby achieving the effect of using the transformer mechanism 4 for transformer control.

[0040] The threaded base 404 is provided with safety plug-in plates 406 on both sides, and a top cylinder 407 is provided above the safety plug-in plates 406. A side socket 408 is provided on the outside of the safety plug-in plates 406, and a connecting pipe 409 is provided below the side socket 408.

[0041] In an embodiment of the present invention, when the equipment malfunctions, the top cylinder 407 is activated to output power and drive the output end of the top cylinder 407 to separate the safety plug 406 from the threaded base 404 and the side socket 408, thereby cutting off the circuit of the equipment and ensuring the safety of the equipment.

[0042] The control mechanism 5 includes a built-in motor 501, a drive gear 502, a driven gear 503, a drive gear 504, an adjusting screw assembly 505, a threaded block 506, an adjusting plate 507, and a housing 508. The built-in motor 501 is located inside the housing 202. The output end of the built-in motor 501 is connected to the drive gear 502, and the drive gear 502 is meshed with the driven gear 503. The driven gear 503 is meshed with the drive gear 504, and the output end of the drive gear 504 is connected to the adjusting screw assembly 505.

[0043] In an embodiment of the present invention, when the equipment is working, the transformer mechanism 4 will generate high temperature. The temperature inside the equipment is measured by the temperature detector built into the equipment. When the temperature is in a state that requires heat dissipation, the built-in motor 501 is started to output power to drive the output end of the built-in motor 501 to drive the drive gear 502 to rotate. The drive gear 502 drives the driven gear 503 and the drive gear 504 to mesh and transmit power, thereby causing the drive gear 504 to drive the adjusting screw group 505 to run in a spiral.

[0044] The adjusting screw assembly 505 is threadedly connected to a threaded block 506, and an adjusting plate 507 is provided on one side of the threaded block 506. A sleeve 508 is provided above the adjusting plate 507.

[0045] In an embodiment of the present invention, the screw block 506 is slidable on the screw assembly 505 by adjusting the screw screw assembly 505. Since the screw block 506 is fixedly connected to the adjusting plate 507, and the adjusting plate 507 and the sleeve 508 are sleeved together, the adjusting plate 507 can be inserted into the sleeve 508 to form an open and closed state when the screw block 506 slides.

[0046] The heat dissipation component 6 includes a rear insertion compartment 601, a heat insulation block 602, a fan shroud 603, and a cooling fan 604. The rear insertion compartment 601 is inserted into the outside of the insertion slot 203. An array of heat insulation blocks 602 are arranged on the outer side of the rear insertion compartment 601. The fan shroud 603, on the upper inner side of the rear insertion compartment 601, is used to install the cooling fan 604.

[0047] In an embodiment of the present invention, when the regulating plate 507 forms an open circuit under the sleeve of the housing 508, the cooling fan 604 on the inner side of the shroud 603 is started to run, so that the wind force generated by the cooling fan 604 carries the heat generated inside the housing component 2 due to the power transformer 4 out of the equipment, thereby ensuring the stability of the equipment operation.

[0048] The working principle of this invention is as follows: In use, a passage is formed by inserting the safety plug 406 between the threaded base 404 and the side socket 408. Then, by adjusting the plug nut 405, the plug connector 403 located below the threaded base 404 is inserted into the transformer body 402 located above the insulating pad 401, forming a closed passage. This achieves the effect of using the transformer mechanism 4 for transformer control. When the equipment is working, the transformer mechanism 4 generates high temperatures. The internal temperature of the equipment is measured by the built-in temperature detector. When the temperature reaches a point where heat dissipation is required, the built-in motor 501 is started to output power, driving the output end of the built-in motor 501 to drive the drive gear 502 to rotate. The drive gear 502 drives the driven gear 503 and the drive gear 504 to mesh and transmit power, thereby causing the drive gear 504 to drive the adjusting screw assembly 505 to run in a spiral motion. By adjusting the screw assembly... The spiral movement of 505 drives the threaded block 506 to slide on the adjusting screw assembly 505. Since the threaded block 506 is fixedly connected to the adjusting plate 507, and the adjusting plate 507 and the housing 508 are sleeved together, the adjusting plate 507 can be inserted into the housing 508 to form an open and closed state when the threaded block 506 slides. When the adjusting plate 507 forms an open circuit under the sleeve of the housing 508, the cooling fan 604 on the inner side of the shroud 603 is started to run. The air force generated by the cooling fan 604 carries the heat generated by the transformer mechanism 4 inside the housing component 2 out of the equipment, thereby ensuring the stability of the equipment operation. When the equipment fails, the top cylinder 407 is started to output power to drive the output end of the top cylinder 407 to separate the safety plug 406 from the threaded base 404 and the side socket 408 to cut off the circuit of the equipment, thereby ensuring the safety of the equipment.

[0049] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
