The three-dimensional wound core transformer is an energy-saving power transformer. It creatively reforms the laminated magnetic circuit structure and three-phase layout of traditional power transformers, making product performance more optimized, such as complete symmetry of the three-phase magnetic circuit, significant power saving effect, greatly reduced noise, stronger heat dissipation and overload capacity, compact structure and small size, etc.

[0003] CN118888280B discloses a three-dimensional wound iron core transformer, comprising a base, wherein a transformer body is arranged at a center position on the top of the base, the transformer body is in a triangular shape, and three groups of identical heat dissipation fins are arranged on the outer wall of the transformer body, and three mounting blocks are arranged at the top edges of three corners of the outer wall of the transformer body, and three lead screws are rotatably installed in through holes provided on the three mounting blocks. The present invention drives the mounting frame to move up and down by driving mechanisms arranged on the tops of the three lead screws, so that the mounting frame drives multiple nozzles arranged at the bottoms of three nozzles to move up and down between the inner walls of the three groups of heat dissipation fins to wash the dust adsorbed on the inner walls. The mounting frame moves up and down and simultaneously drives multiple sponge sleeves connected to the bottom through the side walls of the U-shaped connecting frame to wipe the inner walls of the three groups of heat dissipation fins, and at the same time adsorbs the water remaining on the inner walls, so that the inner walls of the heat dissipation fins are kept clean, thereby improving the cleaning efficiency.

[0004] However, in the prior art, the heat dissipation efficiency of the three-dimensional wound core transformer is low, and the heat dissipation method mainly relies on natural heat dissipation or air cooling. However, under high load or high temperature environment, the heat dissipation efficiency is low, and it is difficult to effectively control the temperature rise, resulting in the winding and the core being in a high temperature state for a long time, accelerating insulation aging, and affecting the life of the equipment. In addition, in a high temperature environment, if the heat dissipation is not timely, it is easy to cause the transformer to catch fire, especially in the case of power failure or unattended operation. It is difficult to suppress the fire in time, increasing the risk of fire spread, and insufficient safety protection. Summary of the invention

[0011] Furthermore, a centrifugal pump is provided in one of the storage spaces, and the relay, centrifugal pump and battery are respectively arranged in different storage spaces. An auxiliary condenser is coiled inside the storage space, and the auxiliary condenser is connected to the main condenser. The auxiliary condenser is fitted with the outer wall of the relay, centrifugal pump or battery.

[0017] The beneficial effects of the present invention are: 1. The present invention divides the heat dissipation space into a heat flow space and a storage space. The main heat generation position of the transformer body is located in the heat flow space. When air flows in the heat flow space, cold air enters from the bottom and hot air is discharged from the top, so that the entire system always maintains a dynamic temperature difference heat exchange process. Guide fins are added to the heat flow space to guide the airflow to be evenly distributed along the surface of the transformer, thereby increasing the heat exchange area. The guide fins are arranged in a wave shape to increase the retention time of the airflow in the heat flow space, thereby increasing the heat exchange area and taking away more heat.

In addition, the relay, centrifugal pump and battery are in direct contact with the auxiliary condenser, and part of their heat during operation can also be taken away through the auxiliary condenser.

The heat flow spaces 511 and the storage spaces 512 are spaced and connected. A storage slot 513 is opened on the outer wall of the heat dissipation shell 3 between each heat flow space 511 and the storage space 512. A fire extinguisher 611 is arranged in the storage slot 513. A relay 711 and a battery 712 are respectively arranged in the storage space 512. A guide fin 811 is longitudinally arranged in the heat flow space 511, and a heat dissipation fin 812 is arranged on the outer wall of the heat dissipation shell 3.

The output end of the fan 814 is connected to the bottom of the storage space 512.

[0036] The storage space 512 is connected to the bottom of the heat flow space 511, and a plurality of nozzles 612 connected to the fire extinguisher 611 are arranged above the heat dissipation shell 3. An electromagnetic valve 613 is arranged at the output end of the fire extinguisher 611. A memory metal sheet 614 is arranged on the outer wall of the transformer body 1 at the heat flow space 511. The memory metal sheet 614 is electrically connected to the battery 712. The electromagnetic valve 613 is electrically connected to the battery 712 through the relay 711, and the fan 814 is powered by the battery 712.

[0037] A guide pipe 911 is provided below the heat flow space 511, and the guide pipe 911 is connected to the storage space 512. A through hole 912 is provided on the guide pipe 911 to connect to adjacent guide fins 811.

[0038] The guide fins 811 are arranged in a wave-like structure, and the distance between adjacent guide fins 811 is 10-20 mm, which increases the heat exchange area, increases the contact amount between air and the inner wall, improves the heat dissipation capacity, accelerates the flow rate of hot air, and enhances the convection effect.

[0039] See also Figure 3 as well as Figure 7-Figure 8 A centrifugal pump 713 is provided in a storage space 512, and the relay 711, the centrifugal pump 713 and the battery 712 are respectively arranged in different storage spaces 512. An auxiliary condenser 714 is coiled inside the storage space 512. The auxiliary condenser 714 is connected to the main condenser 4. The auxiliary condenser 714 is in contact with the outer wall of the relay 711, the centrifugal pump 713 or the battery 712. The main condenser 4 is driven by the centrifugal pump 713. The main condenser 4 takes away the heat after passing through the heat flow space 511. When passing through the storage space 512, the condensate in the main condenser 4 enters the auxiliary condenser 714, and the fan 814 directly contacts the first cold air introduced from the outside with the auxiliary condenser 714, so as to quickly cool down the auxiliary condenser 714.

[0040] A heat dissipation groove 101 is provided above the storage space 512, and an air duct 102 connected to the air outlet end of the fan 814 is provided below the storage space 512. Guide strips 103 are symmetrically provided on both sides of the upper end of the air duct 102, and the guide strips 103 are arranged toward the guide pipe 911. Most of the gas can be led out of the guide pipe 911 through the guide pipe 911, and the other part remains in the storage space 512 for cooling the auxiliary condenser 714 in the storage space 512. The heat in the storage space 512 flows away from the heat dissipation groove 101 to achieve the heat dissipation effect.

[0041] A mesh seat 111 is provided at the lower end of the heat dissipation housing 3, and filters 112 are provided at the bottom and sides of the mesh seat 111. The fan 814 is located inside the mesh seat 111. An exhaust pipe 113 is connected to the upper end of the exhaust port 813. The air outlet end of the exhaust pipe 113 is arranged away from the transformer body 1. The filter 112 can effectively reduce the possibility of external dust entering the heat dissipation space through the fan 814, thereby ensuring the heat dissipation effect.

[0042] A main pipe 121 and a fixed pipe 122 are provided on the upper part of the heat dissipation housing 3, the output ends of multiple fire extinguishers 611 are connected to the main pipe 121, the output end of the main pipe 121 is connected to the end face of the fixed pipe 122, the solenoid valve 613 is arranged between the main pipe 121 and the fixed pipe 122, and the nozzle 612 is connected to the fixed pipe 122. By energizing the solenoid valve 613, the fire extinguishing agent in the fire extinguisher 611 can be sprayed outward through the nozzle 612, and the solenoid valve 613 is powered off to close the connection between the main pipe 121 and the fixed pipe 122.

[0043] like Figure 5-Figure 6 As shown, a rack 131 is provided in the heat flow space 511, a memory metal sheet 614 is arranged in the rack 131, a bracket 132 is provided in the rack 131, a seesaw 133 is rotatably provided at the upper end of the bracket 132, the bracket 132 is located near one end of the seesaw 133, the lower end of the memory metal sheet 614 is connected to the lower part of the rack 131, and the upper end is connected to one end of the seesaw 133.

[0044] A fixed block 134 is provided on the storage rack 131 above one end of the seesaw 133 away from the memory metal sheet 614, a conductive sheet 135 is provided below the fixed block 134, a conductive block 136 adapted to the conductive sheet 135 is provided at the upper end of the seesaw 133, the conductive block 136 is electrically connected to the conductive sheet 135, the conductive block 136 is electrically connected to the battery 712, the conductive sheet 135 is electrically connected to the solenoid valve 613 through the relay 711, the memory metal sheet 614 in the initial state is in a straightened state, and the seesaw 133 is in a straightened state. In the tilted state, the conductive block 136 and the conductive sheet 135 do not contact each other. When the transformer body 1 is abnormally heated, the memory metal sheet 614 reaches the critical deformation value and gradually deforms and bends, thereby pulling one end of the seesaw 133 downward, and one end of the conductive block 136 moves upward until it contacts the conductive sheet 135, realizing a closed circuit. The solenoid valve 613 is energized and a fire extinguishing operation can be performed. The wires used for electrical connection are all heat-insulating and fire-proof wires, and are all connected to the inner wall of the heat dissipation housing 3 to protect the safety of the wires.

[0045] A support plate 137 is rotatably provided above the seesaw 133, and the support plate 137 is connected to the conductive block 136 through a sponge pad 138. When the end surface of the seesaw 133 moves up, the conductive block 136 first contacts the conductive sheet 135. As the angle changes during the rise, the support plate 137 rotates accordingly, so that the surface of the conductive block 136 is always in contact with a larger area of ​​the conductive sheet 135. The provision of the sponge pad 138 makes the contact between the conductive sheet 135 and the conductive block 136 more stable, avoiding the situation of disconnection from time to time during the contact process.

[0046] Working principle: When the inside of the transformer body 1 is hotter, start the fan 814 to introduce external cold air from the lower end of the storage space 512. Since the storage space 512 and the heat flow space 511 are connected at the bottom, the cold air enters the bottom of the heat flow space 511 and quickly contacts the heat flow in the heat flow space 511, causing the heat to flow upward along the guide fins 811 and finally be discharged from the exhaust port 813, while a portion of the heat is discharged from the heat dissipation fins 812 through the heat dissipation shell 3. In addition, the main condenser 4 is wrapped around the outer wall of the transformer body 1, and the heat dissipated by the transformer body 1 is directly water-cooled. When the heat carried away by the condensate enters the storage space 512, the first wave of cold air from the fan 814 will directly contact the main condenser 4 located in the storage space 512, directly cool the main condenser 4, and the cooled condensate enters the heat flow space 511 to continue to absorb heat, taking away the heat in the heat flow space 511, thereby achieving an effective cooling effect.

[0047] If the internal temperature of the transformer body 1 is too high and causes spontaneous combustion, the memory metal sheet 614 directly contacts the hottest position of the outer wall of the transformer body 1, and it can be determined whether the temperature of the transformer body 1 rises abnormally. If the temperature rises abnormally and reaches the spontaneous combustion temperature, the memory metal sheet 614 enters the austenite phase and undergoes reversible deformation. At this time, one end of the seesaw 133 is pulled down, and one end of the conductive block 136 is moved up until it contacts the conductive sheet 135, so that the circuit is closed, the solenoid valve 613 is energized, and the fire extinguisher 611 starts to spray the fire extinguishing agent onto the top of the transformer body 1 through the nozzle 612. When the fire is extinguished, the temperature of the transformer body 1 will gradually decrease, and the memory metal sheet 614 will also cool to the martensite phase, that is, the low-temperature original state. At this time, the contacts are disconnected, the solenoid valve 613 is powered off, and the fire extinguisher 611 stops spraying, so that the fire fighting of the transformer body 1 is more timely, and the damage to the transformer body 1 is greatly reduced.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
