Description

Technical Field

[0001] This invention belongs to the field of transformer technology, and particularly relates to a multiphase transformer. Background Technology

[0002] A transformer is a static electrical device used to transform AC voltage and current to transmit AC electrical energy. It achieves electrical energy transmission based on the principle of electromagnetic induction. Transformers can be classified according to their uses into power transformers, test transformers, instrument transformers, and transformers for special purposes: power transformers are necessary equipment for power transmission and distribution and power distribution to power users.

[0003] Transformers can be classified into single-phase transformers and multi-phase transformers according to the number of power phases. However, the installation of existing multi-phase transformers requires careful and meticulous work from the installers, consuming a great deal of their energy. It is also necessary to avoid shaking or vibration during the installation process, which could damage the internal components of the multi-phase transformer. Therefore, there is a need for a multi-phase transformer that can buffer the shaking or vibration that may occur during the installation process, thus facilitating the installation work. Summary of the Invention

[0004] In view of this, the technical problem to be solved by the present invention is to provide a multiphase transformer that can buffer the shaking or vibration that occurs during installation, thereby facilitating the installation work.

[0005] A multiphase transformer includes a mounting frame and a mounting bracket. The transformer body is fixedly connected inside the mounting bracket. Two sliders are fixedly connected to the mounting bracket, and both sliders are slidably connected to the mounting frame. Multiple buffer parts are slidably connected to the mounting frame. Each buffer part is fixedly connected to the mounting frame with a first compression spring. Multiple cylindrical rollers are fixedly connected to the mounting bracket. The multiple buffer parts can be pressed against the multiple cylindrical rollers by the elastic force of the multiple first compression springs.

[0006] It also includes multiple lifting rings fixed to the mounting frame.

[0007] It also includes multiple retaining bars fixed to the mounting frame, and multiple buffer parts can be tightly pressed against the multiple retaining bars.

[0008] It also includes multiple limiting rods that are slidably connected to the mounting frame, and the multiple limiting rods can be fixed individually by screwing bolts into them. Attached Figure Description

[0019] like Figure 1-3 As shown:

[0020] A multiphase transformer includes a mounting frame 201 and a mounting bracket 101. A transformer body 102 is fixedly connected inside the mounting bracket 101. Two sliders 205 are fixedly connected to the mounting bracket 101, and both sliders 205 are slidably connected to the mounting frame 201. Multiple buffer parts 301 are slidably connected to the mounting frame 201. Each buffer part 301 is fixedly connected to the mounting frame 201 with a first compression spring. Multiple cylindrical rollers 103 are fixedly connected to the mounting bracket 101. The multiple buffer parts 301 can be abutted against the multiple cylindrical rollers 103 by the elastic force of the multiple first compression springs. The multiple cylindrical rollers 103 are grouped in pairs, and each buffer part 301 abuts against the two cylindrical rollers 103 in the group.

[0021] When the transformer is hoisted and moved to a suitable position, the hoisting equipment can be fixed to the mounting frame 201. Then, the hoisting equipment is started to move the mounting frame 201. During the movement of the mounting frame 201, if the mounting frame 201 tilts or vibrates horizontally due to environmental factors, unstable operation of the hoisting equipment, or collision with other obstacles, the multiple first compression springs can always provide elastic force to the multiple buffer parts 301. By utilizing the setting that the multiple buffer parts 301 are always pressed against the cylindrical roller 103, the elastic force can buffer the mounting frame 101 when vibration occurs, thereby avoiding damage to the internal components of the transformer body 102 due to vibration or shaking. This facilitates the installation of the transformer and avoids damage to the transformer during hoisting and installation.

[0022] like Figure 1 As shown:

[0023] It also includes multiple lifting rings 203 fixed to the mounting frame 201.

[0024] Before hoisting, workers can wrap multiple slings around multiple lifting rings 203, so that the installation frame 201 can be lifted smoothly by the hoisting equipment, and the installation frame 101 can move upward smoothly and synchronously with the installation frame 201, thus ensuring the hoisting effect.

[0025] like Figure 1 , Figure 2 , Figure 6 As shown:

[0026] It also includes multiple retaining bars 202 fixed to the mounting frame 201, and multiple buffer parts 301 can respectively abut tightly against the multiple retaining bars 202.

[0027] When environmental factors, unstable operation of the hoisting equipment, or collision with other obstacles cause the mounting frame 201 to tilt to a certain extent or generate vibration in a certain direction, some of the multiple buffer parts 301 that can buffer the situation will slide when the tilting or collision occurs. The buffer parts 301 that cannot buffer the situation or even amplify the shaking amplitude will be blocked by multiple baffles 202 and will not slide. That is, when the mounting frame 101 shows a tendency to vibrate and slide to the right, the mounting frame 101 will contact the two buffer parts 301 on the right side to buffer the situation, while the two buffer parts 301 on the left side of the mounting frame 201 will not move, thus ensuring the buffering effect and improving the protection effect of the transformer body 102.

[0028] like Figure 3 As shown:

[0029] It also includes multiple limiting rods 204 that are slidably connected to the mounting frame 201, and the multiple limiting rods 204 can be fixed by screwing bolts into them.

[0030] Before hoisting, multiple limiting rods 204 are fixed in the appropriate positions by tightening bolts. During the hoisting operation, if the shaking or vibration amplitude of the mounting frame 201 is too large, causing the buffer part 301 in a certain direction to slide too far, the buffer part 301 on that side will press against the limiting rod 204 after contacting it, thereby further limiting the sliding amplitude of the mounting frame 101. This prevents the mounting frame 101 from shaking too much and causing damage to the internal components of the transformer body 102. In other words, when vibration occurs, this transformer can first buffer the vibration force and then limit the vibration amplitude, thereby preventing the damage to the internal components of the transformer body 102 caused by excessive vibration force or amplitude.

[0031] like Figure 4 , Figure 9 As shown:

[0032] It also includes two slide rods 401 that are slidably connected to the mounting bracket 101. Two electric push rods that can push the two slide rods 401 to slide are fixed on the mounting bracket 101. Each of the buffer parts 301 is provided with a threaded hole.

[0033] After being hoisted to the appropriate position, the bolts securing the multiple limiting rods 204 can be loosened. Then, the two sliding rods 401 can be operated to slide downwards, causing both sliding rods 401 to move downwards and push the multiple buffer parts 301 away from the mounting frame 101. Bolts are then screwed into the multiple buffer parts 301 to secure them. Afterwards, the two sliding rods 401 are reset, so that the multiple buffer parts 301 can no longer obstruct the sliding of the mounting frame 101. At this point, the operator can easily operate the mounting frame 101 to slide on the mounting frame 201 to select a suitable position for fixing the mounting frame 101, thus further facilitating the operator's installation work.

[0034] like Figure 3 As shown:

[0035] Each of the buffer sections 301 is fixedly connected to a connecting plate 302, and each connecting plate 302 is detachably connected to a fan with its own power supply by bolts.

[0036] After the installation of the mounting bracket 101 is completed, loosen the bolts used to fix the buffer part 301, so that the multiple buffer parts are automatically slid by the elastic force of the multiple first compression springs. Then, connect the multiple self-powered fans to the multiple connecting plates 302 by tightening the bolts. Then, if the transformer body 102 overheats during normal operation of the transformer, the multiple fans can be started to perform external heat dissipation treatment on the transformer body 102. At the same time, the two sliding rods 401 can be operated to slide up and down periodically, so that the two sliding rods 401 push the multiple buffer parts 301 to slide repeatedly, thereby changing the blowing position of the multiple fans and improving the heat dissipation effect on the transformer body 102.

[0037] like Figure 4 , Figure 9 As shown:

[0038] It also includes multiple slides 404 that are slidably connected to the mounting bracket 101, and each slide 404 is fixedly connected to an auxiliary plate 405.

[0039] Two blowers can be connected to two auxiliary plates 405 by tightening bolts. When the transformer body 102 overheats, multiple slides 404 can slide on the mounting frame 101 and start the blowers. This allows the blowers to work with the fan to further enhance the heat dissipation of the transformer body 102. The blowers are a very mature technology in the prior art and will not be described in detail here.

[0040] like Figure 7 , Figure 9 As shown:

[0041] Each slide bar 401 is rotatably connected to one end of two hinge rods 402, and the other ends of the multiple hinge rods 402 are respectively fixedly connected to multiple slide blocks 404.

[0042] When the two slide rods 401 slide up and down, and then the sliding slide rods 401 reciprocate to move multiple buffer parts 301, thereby changing the blowing position of multiple fans, the two slide rods 401 can simultaneously push one end of multiple hinge rods 402 to move, and then the other end of multiple hinge rods 402 pushes multiple slide blocks 404 to slide, thereby simultaneously changing the position of the blower, and thus simultaneously achieving the two effects of changing the blowing position of the fans and changing the position of the blower.

[0043] like Figure 4 As shown:

[0044] Each of the hinge rods 402 is slidably connected to a cooling strip 403, and each cooling strip 403 is provided with a water inlet and a water outlet.

[0045] A water storage container with a water pump can be connected to the inlet of multiple cooling bars 403 via a hose, and the outlet of the cooling bars 403 can also be connected to the water storage container to form a circulation. When the two slide rods 401 are operated to slide up and down, thereby causing the two hinge rods 402 to move continuously, the multiple cooling bars 403 can be operated periodically to slide on the multiple hinge rods 402, thereby causing the multiple hinge rods 402 with circulating water inside to contact the two side surfaces of the transformer body 102, thereby further improving the heat dissipation effect of the transformer body 102.

[0046] like Figure 8-10 As shown:

[0047] Both the mounting bracket 101 and the mounting frame 201 are provided with multiple threaded holes.

[0048] After placing the mounting frame 201 in a suitable position and sliding the mounting bracket 101 on the mounting frame 201 to a suitable position, bolts can be screwed into the multiple threaded holes on the mounting bracket 101 and the mounting frame 201 to fix the mounting bracket 101 and the mounting frame 201, thereby completing the installation work.
