Description

Technical Field

[0001] The invention relates to the technical field of transformers, and in particular to a transformer with a protective structure. Background Art

[0002] A power transformer is a static electric energy conversion device that works based on the principle of electromagnetic induction. It is mainly used to realize energy transmission and distribution of different voltage levels in AC power systems. Its core function is to convert the AC voltage and current at the input end into output electric energy with the same frequency but adjusted amplitude through magnetic coupling between windings. When the AC power supply is connected to the primary winding, the current-carrying conductor excites the alternating magnetic flux in the magnetic circuit of the iron core. When the time-varying magnetic field penetrates the secondary winding, it generates an induced electromotive force according to Faraday's law of electromagnetic induction. This energy transfer method without mechanical motion enables the transformer to achieve both boost transmission and reduce line losses, and to match the needs of electrical equipment by reducing voltage, becoming a core component for modern power networks to achieve efficient and safe power allocation.

[0003] However, for traditional transformer equipment, traditional transformers have the following defects when operating outdoors: the fixed heat sink cannot actively adjust the heat dissipation area in a low wind speed environment, resulting in uneven heat dissipation. Actual measurements show that the temperature difference in the same winding area can reach more than 25°C. At the same time, when the equipment is in use, in the case of uneven heat dissipation, the local temperature inside the transformer is too high. The insulation materials, windings and other components will be in a high temperature environment for a long time, which will accelerate the aging process. For example, after the insulation material ages, the insulation performance decreases, which can easily cause electrical breakdown and other faults, shortening the service life of the transformer. This needs to be improved. Summary of the invention

[0031] Working principle: When the equipment is working, the umbrella-shaped centrifugal impeller 8 on the top of the box cover 3 is first driven to rotate by natural wind force, and then the umbrella-shaped centrifugal impeller 8 rotates to drive the rotating rod 7 to rotate. When the rotating rod 7 rotates, the bearing 6 is driven to rotate at the same time. As the rotating rod 7 rotates, the gear 2 15 and the circular plate 16 are driven to rotate at the same time. Then, the gear 2 15 rotates to drive the gear 5 36 to rotate, and then the gear 5 36 rotates to drive the rotating rod 5 37 to rotate, and at the same time, the rotating rod 5 37 rotates to drive the pulley 4 38 to rotate at the same time, and then the belt 2 39 is driven to move by the rotation of the pulley 4 38, and then the belt 2 39 is driven to rotate by the movement of the belt 2 39, and at the same time, the pulley 3 35 at the other end of the belt 2 39 is driven to rotate through the pulley 3 The rotation of the rotating rod 4 31 drives the rotating rod 4 31 to rotate synchronously, and then the rotating rod 4 31 drives the gear 3 29 to rotate, and then the gear 3 29 drives the gear 4 30 to rotate, and then the gear 4 30 drives another set of gears 3 29 to rotate, and then the other set of gears 3 29 drives another set of rotating rods 4 31 to rotate synchronously, and then the two sets of rotating rods 4 31 rotate synchronously to drive the fan blades 32 to rotate synchronously, and at the same time, when the rotating rod 1 7 rotates, the pulley 14 is synchronously driven to rotate, and when the pulley 14 rotates, the belt 19 is driven to move, and then the pulley 2 18 set inside the other end is driven to rotate through the movement of the belt 19, and then the rotation of the pulley 2 18 drives the rotating rod 3 17 rotates synchronously, and then the rotating rod three 17 and the rotating rod one 7 rotate synchronously to drive the circular plate one 16 and the circular plate two 20 to rotate simultaneously, and the circular plate one 16 and the circular plate two 20 rotate to drive the tooth block 21 to move, and when the tooth block 21 rotates, it will drive the rack two 25 to move, and the movement of the rack two 25 will synchronously drive the moving block 23 and the rack one 24 to move simultaneously. Because the force of the spring one 26 is lower than the wind force, when the moving block 23 moves, it will drive the spring one 26 to stretch. Then, when the moving block 23 moves, it will drive the fan gear one 13 to rotate. When the fan gear one 13 rotates, it will synchronously drive the rotating rod two 11 and the heat sink 12 to rotate synchronously, and then the natural wind will keep blowing. The umbrella-shaped centrifugal impeller 8 rotates, and the rotation of the umbrella-shaped centrifugal impeller 8 can continuously drive the rotating rod 7 to rotate, and then the continuous rotation of the rotating rod 7 can drive the circular plate 16 and the circular plate 20 to rotate continuously. Due to the number limit of the tooth block 21, when the circular plate 16 and the circular plate 20 rotate, the rack 24 will be separated from the tooth block 21, and then the spring 26 will drive the moving block 23 to perform a reset movement. By continuously driving the heat sink 12 to rotate back and forth and the fan blades 32 to rotate continuously, the transformer can be continuously cooled, the heat dissipation effect of the transformer can be enhanced, and the transformer can be effectively cooled and protected. In addition, air is transferred from the air inlet slot 33 to the fan blades 32, and the protective baffle 34 can prevent foreign matter from entering the air inlet slot 33.

[0032] At the same time, by setting the spring 2 47, when a larger transformer component is placed inside the device, it can effectively ensure that the copper-nickel alloy thermistor push rod 45 can always be attached to the surface of the device. When the temperature inside the transformer rises to the set threshold, the copper-nickel alloy thermistor push rod 45 is heated to produce linear expansion, pushing the top moving plate 48 to move, and the moving plate 48 moves to drive the rotating column 43 to rotate, and then the rotating column 43 rotates to drive the rotating rod 6 41 to rotate, and then the rotating rod 6 41 rotates to drive the closing plate 42 to rotate, and the rotating rod 6 41 rotates to drive the torsion spring 51 to rotate synchronously. At this time, the transformer will be opened from the top through the rotation of the closing plate 42, and emergency heat dissipation can be performed. After the temperature drops, the thermistor push rod shrinks, and the closing plate 42 automatically resets under the reset action of the torsion spring 51.

[0033] When it is necessary to adjust the height or level, the hand first contacts the surface of the handwheel 60, and then the hand rotates to drive the bidirectional threaded rod 58 to rotate. The rotation of the bidirectional threaded rod 58 will drive the two sets of fixed blocks 57 to move outward, and when the fixed block 57 moves, the rotating plate 56 will be driven to rotate. At this time, the rotation of the bidirectional threaded rod 58 will synchronously drive the bevel gear seven 61 to rotate synchronously, and the rotation of the bevel gear seven 61 will drive the bevel gear six 54 to rotate, and then the rotation of the bevel gear six 54 will synchronously drive the support rod 53 to rotate. Since the support rod 53 is threadedly connected to the insertion groove 52, when the support rod 53 and the rotating plate 56 rotate, the equipment will be driven to move slowly to the upper end. When the rotating plate 56 rotates and the support rod 53 rotates, the downward force of the equipment can be reduced from three points, so that the operator can easily turn the handwheel 60. The height adjustment and equipment leveling can be achieved through the movement of the rotating plate 56 and the support rod 53.
