[0002] Amorphous alloy is a new type of material formed by rapidly cooling molten iron-based alloy material under specific conditions before crystallization. Since the metal atoms are in irregular state without crystal lattice and grain boundaries, it is in amorphous state. Amorphous alloy strip has high saturation magnetic induction, high permeability, low coercive force, low loss, low excitation current, and good degree stability and aging stability. The transformer using amorphous alloy strip as the core is one of the most energy-saving transformers. The no-load loss performance of amorphous alloy transformer is superior, and it is especially suitable for the application scenario of long no-load time in the subway industry.

The dry amorphous alloy distribution transformer solves the problem that the distribution transformer cannot be sealed and protected when it rains outside and the problem that the dry amorphous alloy distribution transformer inside the shell generates moisture when there is sufficient sunlight, and meets the use requirements of residents.

[0004] The patent with publication number CN118053651A discloses an energy-saving and environment-friendly amorphous alloy dry transformer, which relates to the technical field of transformers and comprises a walking wheel. When the temperature inside the heat dissipation box is too high, hot air flows into the heat dissipation frame through the heat dissipation pipe, the heat-sensitive rubber inside the heat dissipation frame deforms due to thermal expansion and pushes the two sides of the stamping plate to move outward, so that the gas inside the heat dissipation frame is extruded, the air pressure moves to the support frame, and the contactor one on the inner wall of the support frame slides upward to contact the contactor two, so that the heat dissipation leaves are rotated to cool the transformer inside the heat dissipation box. When the temperature inside decreases, the heat-sensitive rubber contracts, the contactor one and the contactor two are separated, and the cooling stops, thereby reducing the power consumption. The thermal expansion and contraction of the heat-sensitive rubber can make the device more energy-saving and environment-friendly.

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

[0033] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0034] Example 1

[0035] like Figures 1-9 As shown, the structure of an amorphous alloy dry-type distribution transformer includes a transformer casing. A mounting plate 1 is disposed at the top of the transformer casing. Multiple first screws 2 are threaded onto the mounting plate 1, and the first screws 2 are threaded to the top of the transformer casing. A sphere 24 is disposed below the mounting plate 1, with its top fixed to the bottom surface of the mounting plate 1. A support column 12 is also disposed below the mounting plate 1, with the sphere 24 movably embedded in the top of the support column 12. A connecting plate 13 is disposed below the support column 12, and is fixed to the bottom of the support column 12. A heat dissipation mechanism is disposed at the bottom of the connecting plate 13, and an angle adjustment mechanism for driving the rotation of the heat dissipation mechanism is installed on the heat dissipation mechanism.

[0036] In use, take the finished amorphous alloy dry-type distribution transformer shell, and then connect the mounting plate 1 to the top of the transformer shell through the first screw 2, thereby fixing the device inside the transformer shell. Since the top of the ball 24 is fixed to the bottom surface of the mounting plate 1, and the ball 24 is movably embedded in the top of the support column 12, the support column 12 is movable and can rotate in all directions.

[0037] Example 2

[0038] As Figures 1-9 shown, in the case of other parts are same with example 1, the difference between this embodiment and example 1 is that: the heat dissipation mechanism includes driving motor 11, driving motor 11 is located below the connecting disc 13, a plurality of second screw rod 14 is screwed on the connecting disc 13, the second screw rod 14 is screwed with the top of driving motor 11; the power output end 25 of driving motor 11 is located at the bottom of driving motor 11, the driving shaft 26 is arranged below the power output end 25, the upper end of driving shaft 26 is fixedly connected with the power output end 25, a plurality of connecting shafts 27 is arranged on the surface of driving shaft 26 along the circumferential direction of driving shaft 26, one end of connecting shaft 27 is fixedly connected with driving shaft 26, the other end of connecting shaft 27 is fixedly connected with fan blade 7.

[0039] In use, the connecting disc 13 is connected with the top of driving motor 11 through the second screw rod 14, the driving motor 11 is started, the power output end 25 of driving motor 11 drives the driving shaft 26 to rotate, the driving shaft 26 drives the fan blade 7 to rotate, so that the fan blade 7 blows and dissipates heat inside the transformer, and the temperature inside the transformer is suppressed to within 40 degrees.

[0040] Example 3

[0041] As Figures 1-9 shown, in the case of other parts are same with example 2, the difference between this embodiment and example 2 is that: the angle adjusting mechanism includes a ring 10, the inside of the ring 10 is hollow, the driving motor 11 is located in the ring 10, a plurality of supports 3 is arranged between the driving motor 11 and the ring 10, one end of the support 3 is fixedly connected with the driving motor 11, the other end of the support 3 is fixedly connected with the ring 10, and the ring 10 is filled with paraffin.

[0042] The angle adjusting mechanism further includes a paraffin collecting cylinder 9, the paraffin collecting cylinder 9 is located below the driving shaft 26, a plurality of conveying pipes 4 is arranged obliquely around the paraffin collecting cylinder 9, the conveying pipes 4 are arranged in annular array around the paraffin collecting cylinder 9, the lower end of the conveying pipe 4 is fixedly connected with and communicated with the paraffin collecting cylinder 9, and the upper end of the conveying pipe 4 is fixedly connected with and communicated with the ring 10. A plurality of first heaters 18 is arranged above the ring 10, the first heating end 17 of the first heater 18 penetrates through the ring 10 and extends into the inside of the ring 10, and the first heating end is fixedly connected with the ring 10. A plurality of paraffin adding pipes 20 is arranged on the top of the ring 10, the paraffin adding pipe 20 is fixedly connected with and communicated with the ring 10. A plurality of heat conducting ropes 5 is fixedly arranged on the ring 10, the heat conducting rope 5 extends into the inside of the ring 10, and one end of the heat conducting rope 5 away from the ring 10 is fixedly provided with a heat conducting sheet 6.

[0043] The heat conducting sheet 6 is fixed at the easily heated part inside the transformer, so that the heat conducting sheet 6, the connection part of the heat conducting rope 5 and the ring 10, and the power output end 25 of the driving motor 11 are located in the same plane.

[0044] When abnormal heat is generated at a certain point inside the transformer, the heat is transferred to the ring 10 through the heat-conducting plate 6 and the heat-conducting rope 5, causing the paraffin at the connection between the heat-conducting rope 5 and the ring 10 to gradually melt. The melted paraffin transfers heat to the paraffin in the conveying pipe 4 connected to it, causing the paraffin in the conveying pipe 4 to melt synchronously, so that the melted paraffin flows into the paraffin collection cylinder 9 through the conveying pipe 4.

[0045] As the paraffin wax in that section of the ring 10 gradually melts and decreases, the weight of that section of the ring 10 decreases, causing the center of gravity of the ring 10 to shift. The half of the ring 10 missing paraffin wax rises, while the other half lowers. This causes the ring 10, via the bracket 3, to drive the motor 11 to rotate towards the area where the malfunction occurred, ultimately directing the fan blades 7 directly at the hot spot, accelerating heat dissipation and cooling.

[0046] Example 4

[0047] like Figures 1-9 As shown, while all other parts are the same as in Example 3, the difference between this example and Example 2 is that the top of the paraffin wax adding tube 20 is threadedly connected to the sealing cap 19. The top of the paraffin wax adding tube 20 is threadedly connected to the bottom of the connecting tube 22, and a funnel 21 is provided above the connecting tube 22. The bottom of the funnel 21 is fixedly connected to and communicates with the top of the connecting tube 22.

[0048] A sealing plug 16 is provided at the top of the paraffin collection cylinder 9. The sealing plug 16 is threadedly connected to the paraffin collection cylinder 9. A limiting cover 15 is provided above the sealing plug 16. The limiting cover 15 is fixedly connected to the top of the sealing plug 16. A second heater 8 is provided below the paraffin collection cylinder 9. The second heating end 23 of the second heater 8 passes through the paraffin collection cylinder 9 and extends into the interior of the paraffin collection cylinder 9. The second heating end 23 is fixedly connected to the paraffin collection cylinder 9.

[0049] After a certain amount of paraffin wax is collected in the paraffin wax collection cylinder 9, the sealing plug 16 is removed, and then the second heater 8 and the first heater 18 are turned on. The first heating end 17 of the first heater 18 heats and melts the paraffin wax inside the ring 10, and the second heating end 23 of the second heater 8 melts the paraffin wax inside the paraffin wax collection cylinder 9. Then, the paraffin wax in the paraffin wax collection cylinder 9 is taken out, the sealing cap 19 is removed, and the connecting pipe 22 is threadedly connected to the paraffin wax adding pipe 20. The taken-out paraffin wax is then added back into the ring 10 through the funnel 21 to replenish the paraffin wax in the ring 10.

[0050] Further, after the paraffin wax in the paraffin wax collecting cylinder 9 is taken out, the sealing plug 16 is rethreaded with the paraffin wax collecting cylinder 9, so that the sealing plug 16 blocks the connection between the delivery pipe 4 and the paraffin wax collecting cylinder 9, so that when the taken-out paraffin wax is readded into the circular ring 10 through the funnel 21, the paraffin wax will not flow into the paraffin wax collecting cylinder 9 through the delivery pipe 4 any more. After the paraffin wax to be introduced is solidified, the sealing plug 16 is reversely rotated so that the sealing plug 16 no longer blocks the connection between the delivery pipe 4 and the paraffin wax collecting cylinder 9.

[0051] The basic principles and main features of the present application and the advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above-described embodiments, and the above-described embodiments and the description in the specification are only illustrative of the principles of the present application.
