Description

Technical Field

[0001] This utility model relates to the technical field of medium and high voltage water-cooled rectifier transformers, and in particular to a medium and high voltage water-cooled rectifier transformer that facilitates heat dissipation. Background Technology

[0002] Medium and high voltage water-cooled rectifier transformers are special transformers designed specifically for high-power rectifier systems. They are widely used in industries with high DC power requirements, such as metallurgy (e.g., vacuum arc furnaces for sponge titanium), chemical industry, electrolysis, and rail transportation. Their core feature is the combination of water-cooling technology and rectifier transformation functions, solving the heat dissipation bottleneck problem under high current and high power density conditions.

[0003] Existing medium- and high-voltage water-cooled rectifier transformers typically dissipate heat into the outside air during operation. However, during peak electricity consumption periods, the overall temperature of these transformers is high, and the efficiency of dissipating heat into the air is limited, resulting in insufficient overall heat dissipation and an inability to quickly cool down the system. Therefore, we propose a medium- and high-voltage water-cooled rectifier transformer that facilitates heat dissipation. Utility Model Content

[0032] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0033] Example:

[0034] like Figures 1-7 As shown, a medium- and high-voltage water-cooled rectifier transformer that facilitates heat dissipation includes a transformer body 1. A connecting base frame 2 is symmetrically provided at the bottom end of the transformer body 1. A first mounting hole 4 and a second mounting hole 5 are symmetrically opened on the surface of the connecting base frame 2. A connecting heat dissipation mechanism 3 is movably sleeved on the outer side of the surface of the transformer body 1. The connecting heat dissipation mechanism 3 is connected and installed to the top of the connecting base frame 2 by threaded fasteners.

[0035] The working principle of the above technical solution is as follows:

[0036] During use, the heat dissipation mechanism 3 can dissipate heat from the entire connecting base frame 2. In subsequent use, the internal components of the heat dissipation mechanism 3 can be quickly disassembled for rapid inspection and maintenance. The overall structure is simple and the operation is convenient and quick.

[0037] In another embodiment, such as Figure 3As shown, the connecting heat dissipation mechanism 3 includes a connecting mounting frame 31. Ventilation holes 36 are provided on both sides and the rear surface of the connecting mounting frame 31. A fixing through groove 32 is provided on the top of the connecting mounting frame 31. Connecting side covers 33 are fixedly connected to both sides of the connecting mounting frame 31. A connecting rear cover 34 is fixedly connected to the rear surface of the connecting mounting frame 31. A rectangular through groove is provided on the front surface of the connecting mounting frame 31. First limiting blocks 35 are symmetrically provided at the bottom end of the connecting side covers 33. A connecting... The limiting frame 37 and the connecting mounting frame 31 have symmetrically opened fixed threaded holes 38 on their front surfaces. The connecting limiting frame 37 is movably inserted with a connecting exhaust assembly 39. The lower middle part of the rear surface of the connecting rear cover 34 is fixedly connected with a connecting positioning assembly 310. The bottom end of the connecting rear cover 34 is symmetrically provided with a second limiting block 313. The bottom front and rear ends of the connecting mounting frame 31 are symmetrically provided with connecting feet 311. The inner sides of the first limiting block 35 and the second limiting block 313 are movably inserted with a connecting filter assembly 312.

[0038] During operation, the connecting exhaust assembly 39 can exhaust the air inside the connecting mounting frame 31 to the outside. At the same time, the outside air can be filtered by the connecting filter assembly 312 and then supplied to the inside of the connecting mounting frame 31 to absorb the internal heat. The air is then exhausted to the outside again through the connecting exhaust assembly 39, thus achieving stable heat dissipation and making operation convenient.

[0039] In another embodiment, such as Figure 5 As shown, the connecting exhaust assembly 39 includes a connecting mounting plate 391. A connecting mounting cylinder 392 is fixedly connected to the middle of the front surface of the connecting mounting plate 391. An exhaust fan 393 is provided on the inner side of the connecting mounting cylinder 392. A connecting protective plate 394 is fixedly connected to the front end of the connecting mounting cylinder 392. Fixed handles 395 are symmetrically provided on the front surface of the connecting mounting plate 391. Fixed connecting seats 396 are symmetrically provided on the upper part of the front surface of the connecting mounting plate 391. A movable deflection arm 397 is movably connected to the inner side of the fixed connecting seat 396 through a connecting shaft. A fixed through hole 398 is provided at the end of the movable deflection arm 397.

[0040] This facilitates the insertion of the connecting mounting plate 391 into the inner side of the connecting limiting frame 37. Then, one end of the movable deflection arm 397 is deflected inside the fixed connecting seat 396, so that one side of the movable deflection arm 397 fits against the surface of the connecting mounting frame 31 and is connected and fixed by bolts. This allows the exhaust fan 393 to be used stably, exhausting the hot air inside the connecting mounting frame 31 to the outside, thereby achieving stable heat dissipation and convenient operation.

[0041] In another embodiment, such as Figure 5As shown, the end of the movable deflection arm 397 is connected and fixed to the surface of the connecting mounting frame 31 by bolts.

[0042] The movable deflection arm 397 can be stably connected to the connecting mounting frame 31 via threads, making operation convenient.

[0043] In another embodiment, such as Figure 6 As shown, the connection positioning assembly 310 includes a connection mounting sleeve 3101. A movable positioning rod 3102 is movably connected inside the connection mounting sleeve 3101. A force-bearing collar 3103 is fixedly sleeved on the outer surface of the movable positioning rod 3102. A force-bearing spring 3104 is fixedly connected between the top of the force-bearing collar 3103 and the inner top of the connection mounting sleeve 3101. A connection pull ring 3105 is fixedly connected to the top of the movable positioning rod 3102.

[0044] The connecting pull ring 3105 is easy to pull up, which drives the movable positioning rod 3102 and the force-bearing collar 3103 to move, compressing the force-bearing spring 3104, thereby making quick adjustment and convenient to use.

[0045] In another embodiment, such as Figure 7 As shown, the connecting filter assembly 312 includes a first filter plate 3121 and a second filter plate 3122 that are movably inserted into the inner sides of the first limiting block 35 and the second limiting block 313. One end of the first filter plate 3121 and the second filter plate 3122 are fixedly connected to a connecting mounting bracket 3125. The first side block 3123 is fixedly connected to both sides of the first filter plate 3121, and the second side block 3124 is fixedly connected to both sides of the second filter plate 3122. A fixing positioning sleeve block 3126 is fixedly connected to the middle of one side of the connecting mounting bracket 3125, and a connecting handle 3127 is symmetrically provided on one side of the connecting mounting bracket 3125.

[0046] This allows the first filter plate 3121 and the second filter plate 3122 to be stably inserted into the inner side of the first limiting block 35 and the second limiting block 313. Then, the fixed positioning sleeve 3126 is connected and engaged with the connecting positioning component 310 to perform installation and positioning, thereby ensuring stable use and convenient operation.

[0047] In another embodiment, such as Figure 7 As shown, the outer surface of the bottom end of the movable positioning rod 3102 slides and fits against the inside of the fixed positioning sleeve 3126.

[0048] The bottom end of the movable positioning rod 3102 can be stably inserted into the fixed positioning sleeve 3126 for connection and positioning, making operation convenient.

[0049] The working principle of this utility model is as follows: During use, the entire assembly is first connected. Then, the exhaust fan 393 operates, expelling air from the inside of the connecting frame 31 to the outside. Simultaneously, external air is filtered by the first filter plate 3121 and the second filter plate 3122 before being supplied to the inside of the connecting frame 31. This absorbs heat from inside the connecting frame 31, which is then expelled to the outside by the exhaust fan 393, thus achieving stable heat dissipation. In subsequent use, when disassembly and maintenance of the exhaust fan 393, the first filter plate 3121, and the second filter plate 3122 are required, first, the bolts connecting the movable deflection arm 397 to the connecting frame 31 are rotated and disassembled. Then, the movable deflection arm 397 is deflected so that it can deflect inside the fixed connecting seat 396. Finally, the fixed handle 395... Move upwards to allow the connecting mounting plate 391 to detach from the inside of the connecting limiting frame 37, enabling quick disassembly, inspection, and maintenance. Then, pull the connecting pull ring 3105 to move the movable positioning rod 3102 and the force-bearing collar 3103, compressing the force spring 3104. This causes the bottom end of the movable positioning rod 3102 to be pulled out from the inside of the fixed positioning sleeve 3126, ceasing connection and positioning. Then, pull the connecting handle 3127 to move the connecting mounting frame 3125, the second filter plate 3122, the second side block 3124, the first filter plate 3121, and the first side block 3123. This allows the first filter plate 3121, the first side block 3123, the second filter plate 3122, and the second side block 3124 to be pulled out from the inside of the first limiting block 35 and the second limiting block 313, respectively, enabling disassembly, inspection, and maintenance. The overall structure is simple and the operation is convenient and quick.

[0050] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
