Description

Technical Field

[0001] The invention relates to the technical field of transformers, and in particular to a box-type transformer suitable for outdoor use. Background Art

[0002] Transformers are common and important equipment in power systems. Their main function is to achieve the rise and fall of AC voltage through the principle of electromagnetic induction. They are widely used in power transmission and distribution, industrial production, building power supply and other fields. When the transformer is working, its external structure is under a certain load. Especially in high wind speed environments, the impact of external wind on the transformer is more significant. Therefore, when designing the external support system of the transformer, windproof design becomes an important technical issue.

[0003] The external structure of the transformer is usually composed of a metal casing and a heat sink, etc. These components have a certain wind resistance area, especially for transformers installed in open air or high wind speed areas. The wind acting on these structures may generate strong lateral and torsional forces on the transformer body, resulting in the following potential problems for the transformer: 1. Structural deformation and damage: The direct effect of strong winds will affect the normal operation of the equipment, especially when exposed to high wind speeds for a long time, structural parts may suffer fatigue damage or even rupture.

[0004] 2. Safety hazards: Wind force may cause the transformer to shake or move, which will not only affect the stability of the equipment, but also pose a threat to the safety of surrounding facilities and personnel, causing serious safety accidents.

[0005] 3. Generate vibrations: Wind not only acts on the transformer through lateral force, but may also be transmitted to the transformer through the windproof structure of the equipment to cause vibrations and other phenomena. These vibrations can cause potential damage to the internal electrical components, mechanical structure and external equipment of the transformer. Summary of the invention

[0006] In view of the deficiencies in the prior art, the purpose of the present invention is to propose a box-type transformer suitable for outdoor use.

[0015] The present invention also claims a method for using a box-type transformer suitable for outdoor use, comprising the following steps: S1: Drive the wind speed sensor to monitor the wind speed. When the wind speed is greater than the threshold set by the controller, the controller drives the motor to rotate. The rotation of the motor drives the rotating shaft to rotate, and at the same time drives the chain to rotate; when the sprocket rotates, the chain that meshes with the sprocket rotates, thereby driving the sprockets and the rotating shaft around the box to rotate; when the chain rotates, the connecting block fixedly connected between the chain and the slider drives the slider to slide to the other end of the sliding track. At this time, the sliding shaft slides between the upper and lower sliding tracks. At the same time, the rotation of the rotating shaft also drives the sliding shaft to stretch toward the other end of the sliding track, so that the plastic wind shield is gradually opened. When opening, the first supporting component located on the inner side of the plastic wind shield is also gradually opened. When the first supporting component is opened, the resilience of the plastic sleeve makes it gradually straighten. At the same time, through the tension of the fifth spring connected on both sides, the plastic sleeve is rotated along the mounting seat toward the vertical direction of the plastic wind shield. After driving the first spring to rotate, the first The bottom of the spring abuts against the plastic wind shield plate. At the same time, when the plastic sleeve straightens back, the first supporting connecting block and the second supporting connecting block inside also straighten back, driving the second spring inside to be tightened, and the first supporting connecting block and the second supporting connecting block are connected and tightened through the conical circular groove and the conical circular protrusion; the first supporting connecting block at the lowest end abuts against the top of the first spring; as the plastic wind shield plate continues to open, when the top of the second supporting connecting block contacts the notch of the semi-cylinder, under the pull of the fifth spring, the second supporting connecting block is pressed against the arc-shaped sliders on both sides, and under the compression force of the internal third spring, the arc-shaped slider slides into the arc-shaped groove to squeeze the third spring, so that the second supporting connecting block slides into the interior of the semi-cylinder, at this time, the third spring is not subjected to force, so that the arc-shaped slider returns to its position, limiting the second supporting connecting block; after limiting, the plastic wind shield plate slides to the other end of the sliding track, stops the rotation of the motor, and realizes that multiple plastic wind shields resist wind from the box body; S2: When the wind speed drops to the low threshold value set by the controller, the driving motor reverses, and the rotation of the motor drives the shaft to reverse, and at the same time drives the chain to reverse; when the sprocket reverses, the chain meshing with the sprocket reverses, and when the chain reverses, the connecting block fixedly connected between the chain and the slider drives the slider to slide toward the other end of the plastic windshield, and at this time the sliding shaft slides in the opposite direction between the upper and lower sliding tracks, and at the same time the reversal of the shaft also drives the sliding shaft to slide toward the other end of the plastic windshield; the plastic windshield gradually closes, and the second supporting connecting block is pulled, and when it is pulled , presses toward the arc-shaped slider, and the arc-shaped slider slides into the arc-shaped groove to squeeze the third spring, so that the second supporting connecting block is separated from the semi-cylinder, and curled under the continued recovery of the plastic wind shield. During curling, the plastic sleeve rotates at the hinge, driving the first spring to tilt and press down, and at the same time the second spring is stretched. Under the curling of the plastic wind shield, the curling force of the plastic wind shield is dispersed between multiple first supporting connecting blocks through the plastic wind shield, and the fifth spring is also compressed, curled, and gathered into the plastic wind shield; when the slider slides to the edge of the sliding groove, the rotation of the motor is stopped, and the winding of the plastic wind shield is completed.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) The windshield assembly provided in the present invention monitors the wind speed and takes windshield measures. When the wind speed is high, the plastic windshield is opened to surround the transformer to intercept the wind. At the same time, the arc-shaped setting of the plastic windshield allows the wind to pass through the outside of the windshield more smoothly, avoiding the transformer body from generating strong lateral force and torsional force, thereby causing structural deformation and damage. At the same time, when the plastic windshield is opened, springs are provided at both ends of the first support connecting plate and the second support connecting plate after they are connected, so as to provide middle support for the plastic windshield. At the same time, when the wind speed is high, the plastic windshield is also damped by the setting of the support shock-absorbing assembly to prevent the shaking generated by the plastic windshield from being transmitted to the transformer and causing damage to the components inside the transformer, thereby preventing resonance and ensuring the stability of the transformer operation.

[0017] (2) The windshield assembly of the present invention can be folded up when not in use, and the first supporting member supporting the shock absorbing assembly is clamped in the plastic windshield plate, which accelerates the heat dissipation of the transformer and prevents the transformer from being not folded up when not in use, resulting in low heat dissipation efficiency of the transformer.

DETAILED DESCRIPTION

[0020] The preferred embodiments of the present invention are described below in conjunction with the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In addition, the embodiments of the present invention and the features in the embodiments may be combined with each other if there is no conflict. Example 1

[0021] like Figure 1 to Figure 7As shown, a box-type transformer suitable for outdoor use comprises a box body 100, a high-voltage bushing 110 and a low-voltage bushing 120 are arranged on a top plate 150 of the box body 100, an oil pillow 130 is also installed on the top of the box body 100, a radiator 140 is arranged on the side walls around the box body 100, a base 200 is arranged at the bottom of the box body 100, a plurality of windshield components 300 are arranged on the base 200, and the windshield components 300 are located around the box body 100; a wind speed sensor is also installed on the top plate 150, and the wind speed sensor is electrically connected to a controller, and the controller is installed on the box body 100; The windshield assembly 300 includes a rotating shaft 310 installed on the corner of the base 200, and the rotating shaft 310 is vertically rotatably connected between the top plate 150 and the base 200. A rollable plastic windshield 320 is fixed on the rotating shaft 310, and one end of the plastic windshield 320 is fixedly connected to the rotating shaft 310, and the other end of the plastic windshield 320 is fixedly connected to a sliding shaft 330, and sliders 340 are provided at both ends of the sliding shaft 330; sliding rails 350 are symmetrically fixed under the top plate 150 of the box 100 and on the base 200, and the sliding rails 350 are located on one side of the box 100, and the sliders 340 located at both ends of the sliding shaft 330 are both slidably connected in the sliding rails 350, and at least two groups of supporting shock-absorbing components 400 are also installed between the plastic windshield 320 and the side wall of the box 100.

[0022] The wind speed sensor is used to monitor the wind speed at the transformer installation location, and the controller is used to receive the wind speed data detected by the wind speed sensor and control the wind shield assembly 300 according to the relevant data. When the wind speed is high, the wind shield assembly 300 is opened for wind protection, and when the wind speed decreases, the wind shield assembly 300 is closed for folding to maintain good heat dissipation performance. It should be noted that the controller is a PLC controller, and a battery is installed in the controller to provide long-term power for it.

[0023] Whether the windshield assembly 300 blocks wind mainly depends on whether the plastic windshield plate 320 is unfolded. One end of the plastic windshield plate is connected to the rotating shaft 310, and the other end is connected to the sliding shaft 330. The sliding shaft 330 slides on the sliding track 350 to unfold and achieve wind blocking. The plastic windshield plate 320 is arc-shaped when it is turned open, which can reduce resistance, allow wind to pass through better, and reduce the vibration caused by wind passing through.

[0024] In this embodiment, sprockets 370 are fixedly installed at both ends of the rotating shaft 310, and chains 380 are provided on the top and bottom of the box body 100, one of the chains 380 is meshed and connected between the multiple sprockets 370 at the bottom, and the other chain 380 is meshed and connected between the multiple sprockets 370 at the top; a sprocket slideway 351 is provided on the sliding track 350, and the chains 380 located between adjacent sprockets 370 are all slidably connected to the outside of the sprocket slideway 351; a plurality of connecting blocks 390 are evenly fixed on the chain 380; one end of the connecting block 390 is fixed to the chain 380, and the other end of the connecting block 390 is fixedly connected to the corresponding slider 340; a motor is fixedly installed on the top plate 150 or the base 200 of the box body 100, and the output end of the motor is fixedly connected to one end of one of the rotating shafts 310, and the motor is electrically connected to the controller.

[0025] The motor drives the rotating shaft 310 to rotate, so that multiple groups of windshield assemblies 300 can be unfolded or reeled up at the same time. The motor drives the sprocket 370 and the rotating shaft 310 to rotate, so that the chain 380 drives the slider 340 to slide to the other side of the connected rotating shaft 310. At the same time, the rotation of the rotating shaft 310 will also push the plastic windshield plate 320 forward. The two work together to enable the plastic windshield plate 320 to be better unfolded, thereby achieving the purpose of windshielding the transformer.

[0026] In this embodiment, the support and shock absorbing component 400 includes a first support component 410 installed on the plastic windshield plate 320 and a second support component 420 fixedly installed on the outer side wall of the box body 100; The first supporting component 410 includes a plastic sleeve 411 rotatably connected to the mounting seat 416 inside the plastic windshield 320, a first spring 413 is placed at the bottom of the plastic sleeve 411, a plurality of first supporting connecting blocks 412 are slidably connected to the middle of the plastic sleeve 411, and a second supporting connecting block 414 is slidably connected to the top of the plastic sleeve 411; a through hole is provided in the middle of the first supporting connecting block 412, a first connecting block 415 is provided at the bottom of the second supporting connecting block 414, a second connecting block 417 is provided on the inner side of the mounting seat 416, a second spring 418 is hinged on the second connecting block 417, the other end of the second spring 418 passes through the middle of the first spring 413 and the through hole and is hinged to the first connecting block 415; fifth springs 419 are also connected to both sides of the plastic sleeve 411, one end of the fifth spring 419 is hinged to the side wall of the plastic sleeve 411, and the other end of the fifth spring 419 is hinged to the connecting seat 430.

[0027] When the plastic windshield 320 is opened, the first support component 410 is spread open so as to be connected to the second support component 420. After the two are connected, good shock absorption and support effects can be achieved, and the plastic windshield 320 can be prevented from being deformed. At the same time, the vibration generated by the plastic windshield 320 when blocking the wind can be prevented from being transmitted to the transformer, thereby avoiding damage to the internal structure of the transformer and ensuring the stable operation of the transformer. The plastic sleeve 411 is used to cover the first support connection block 412 and the second support connection block 414, so that when it becomes a straight cylinder after rebounding, it can drive the first support connection block 412 and the second support connection block 414 to be connected into one body. At the same time, the first spring 413 and the second spring 418 are set to assist the first support connection block 412 and the second support connection block 414 to be connected into a straight line. The fifth spring 419, when opened, can first support the plastic sleeve 411 on both sides of the plastic sleeve 411, so as to facilitate its rotation in the vertical direction of the plastic wind shield 320. Later, the fifth spring 419 is used to generate a pulling force on the second support connection block 414, so that when the second support connection block 414 reaches the cutout of the semi-cylinder 422, the second support connection block 414 can slide into the semi-cylinder 422 under the continued stretching of the plastic wind shield 320. The setting of the first spring 413 and the fourth spring 427 enables the support and shock-absorbing component 400 to achieve the supporting and shock-absorbing effects.

[0028] In this embodiment, the second supporting member 420 includes a second sleeve 421 fixedly connected to the outer wall of the box body 100, the top of the second sleeve 421 extends out of the outside of the radiator 140, and a semi-cylinder 422 is provided at one end of the second sleeve 421 away from the box body 100, and arc grooves 423 are provided on both sides of the semi-cylinder 422, and an arc through hole 424 is provided in the semi-cylinder 422 between the two arc grooves 423, and a third spring 425 is clamped in the arc through hole 424, and both ends of the third spring 425 extend out of the arc through hole. The hole 424 is located in the arc groove 423, and an arc slider 426 slides in the arc groove 423 on both sides. The side of the arc slider 426 located in the arc groove 423 is fixedly connected to the third spring 425; a fourth spring 427 is installed on the inner side of the second sleeve 421, and the bottom of the fourth spring 427 is fixedly connected to the side wall of the box body 100. When the top of the second supporting connecting block 414 is located in the semi-cylinder 422, the end of the second supporting connecting block 414 located in the semi-cylinder 422 can be contacted and abutted with the fourth spring 427.

[0029] The third spring 425 is provided so that the arc-shaped slider 426 can be slidably connected in the arc-shaped groove 423. When the second supporting connecting block 414 reaches the notch, the arc-shaped slider 426 is squeezed, and the arc-shaped slider 426 squeezes the third spring 425 inward, so that the second supporting connecting block 414 slides into the semi-cylinder 422 to achieve a overlapping effect. At the same time, the arc-shaped slider is provided so that the second supporting connecting block 414 is not easy to separate from the semi-cylinder 422 without external force.

[0030] Furthermore, the arc-shaped slider 426 can be located on one side outside the arc-shaped groove 423 and provided with an outward flare to facilitate the second supporting connecting block 414 to dock with the notch of the semi-cylinder 422, thereby avoiding misalignment that causes unsuccessful overlap between the top of the second supporting connecting block 414 and the semi-cylinder 422.

[0031] In this embodiment, the material of the plastic windshield plate 320 is one of stainless steel, aluminum alloy, polyester film or carbon steel; the material of the plastic sleeve 411 is polyester film or nylon.

[0032] In this embodiment, a sliding groove 352 is provided on the sliding rail 350, and arc-shaped sliding holes 353 are provided on the sliding rail 350 on both sides of the sliding groove 352. Both sides of the slider 340 are located in the arc-shaped sliding holes 353, and the other end of the connecting block 390 is fixedly connected to the slider 340 through the arc-shaped sliding hole 353.

[0033] The two sides of the slider 340 are clamped in the arc-shaped sliding hole 353 to facilitate positioning. At the same time, it is convenient to fix the connecting block 390 and the slider to achieve a better transmission effect.

[0034] In this embodiment, a conical circular groove 4121 is provided at the top of the first supporting and connecting block 412, and a conical circular protrusion 4122 is provided at the bottom of the first supporting and connecting block 412, and two adjacent first supporting and connecting blocks 412 are connected by the conical circular groove 4121 and the conical circular protrusion 4122; a conical circular protrusion 4122 is also provided at the bottom of the second supporting and connecting block 414, and the bottom of the second supporting and connecting block 414 is connected to the conical circular groove 4121 on the top of the adjacent first supporting and connecting block 412 through the conical circular protrusion 4122.

[0035] The matching arrangement of the conical circular groove 4121 and the conical circular protrusion 4122 enables the first supporting connection block 412 and the second supporting connection block 414 to be better engaged, and the supporting effect is better.

[0036] In this embodiment, a C-shaped steel is fixedly connected to the bottom of the base 200 .

[0037] The setting of C-shaped steel makes it convenient for the installation of the transformer. Example 2

[0038] A method for using a box-type transformer suitable for outdoor use comprises the following steps: S1: Drive the wind speed sensor to monitor the wind speed. When the wind speed is greater than the threshold value set by the controller, the controller drives the motor to rotate. The rotation of the motor drives the shaft 310 to rotate, and at the same time drives the chain 380 to rotate; when the sprocket 370 rotates, the chain 380 meshing with the sprocket 370 rotates, thereby driving the sprockets 370 and the shaft 310 around the box 100 to rotate; when the chain 380 rotates, the connecting block 390 fixedly connected between the chain 380 and the slider 340 drives the slider 340 to slide toward the other end of the sliding track 350. At this time, the sliding shaft 330 moves along the upper The plastic windshield 320 slides between the two lower sliding rails 350, and the rotation of the rotating shaft 310 also drives the sliding shaft 330 to stretch toward the other end of the sliding rail 350, so that the plastic windshield 320 is gradually opened. When opening, the first supporting component 410 located on the inner side of the plastic windshield 320 is also gradually opened. When the first supporting component 410 is opened, the resilience of the plastic sleeve 411 makes it gradually straighten. At the same time, through the tension of the fifth spring 419 connected on both sides, the plastic sleeve 411 rotates along the mounting seat 416 toward the vertical direction of the plastic windshield 320, driving the first spring 413 to rotate, and the first spring 413 rotates. 3, the bottom of the plastic windshield 320 abuts against the plastic windshield 320. At the same time, when the plastic sleeve 411 straightens, the first supporting connection block 412 and the second supporting connection block 414 inside also straighten, driving the second spring 418 inside to be tightened, and the first supporting connection block 412 and the second supporting connection block 414 are connected and tightened through the conical circular groove 4121 and the conical circular protrusion 4122; the first supporting connection block 412 at the lowest end abuts against the top of the first spring 413; as the plastic windshield 320 continues to open, when the top of the second supporting connection block 414 contacts the notch of the semi-cylinder 422, at the fifth Under the pull of the spring 419, the second support connection block 414 is pressed against the arc-shaped sliders 426 on both sides. Under the compression force of the internal third spring 425, the arc-shaped slider 426 slides into the arc-shaped groove 423 to squeeze the third spring 425, so that the second support connection block 414 slides into the semi-cylinder 422. At this time, the third spring 425 is not subjected to force, so that the arc-shaped slider 426 returns to the position, and the second support connection block 414 is limited. After the position is limited, the plastic windshield plate 320 slides to the other end of the sliding track 350, stops the rotation of the motor, and realizes that the multiple plastic windshield plates 320 resist the wind for the box body 100.

When the wind speed is greater than a threshold value set by the controller, the controller drives the motor to rotate. The rotation of the motor drives the rotating shaft (310) to rotate, and at the same time drives the chain (380) to rotate. When the sprocket (370) rotates, the chain (380) meshing with the sprocket (370) rotates, thereby driving the sprockets (370) and the rotating shaft (310) around the box (100) to rotate. When the chain (380) rotates, the connecting block (390) fixedly connected between the chain (380) and the slider (340) drives the slider (340) to slide toward the other end of the sliding track (350).
