Description

Technical Field

[0001] This invention relates to the field of transformer equipment technology, specifically to a nanocrystalline toroidal encapsulated transformer. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are the primary coil, secondary coil, and iron core. Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization. In existing technology, the transformer itself is a crucial component in the circuit operation process. However, traditional transformers generate a large amount of heat during operation. This heat accumulation leads to temperature rise, and excessively high temperatures can corrode the internal components of the transformer. A solution is needed to address these technical problems.

[0003] As described in the patent document with publication number CN211265215U, the device uses a first motor, a transmission belt, a toothed gear, a transmission shaft, a first gear, a torsion spring, heat dissipation fins, and a mounting shaft to generate airflow through a mechanical structure and dissipate heat, thereby accelerating the heat dissipation speed; and uses a second motor, a second gear, a rack, and a partition to assist the device in heat dissipation by opening and closing the heat dissipation vents.

[0004] However, the aforementioned device requires drilling holes in the transformer casing to dissipate heat, which can easily cause dust to enter the transformer casing, affecting the normal operation of the transformer. External heat sinks alone are insufficient to effectively dissipate heat from the transformer casing. Furthermore, when the transformer is operating under high load, the heat sinks are less efficient at dissipating heat, preventing heat from being dissipated in time and reducing the transformer's lifespan. Summary of the Invention

[0005] The technical problem that this solution addresses is:

[0006] (1) How to solve the problem of ensuring rapid cooling of transformers under high load conditions;

[0007] (2) How to solve the problem of effective heat dissipation of transformers under normal working conditions.

[0008] The objective of this invention can be achieved through the following technical solution: a nanocrystalline toroidal encapsulated transformer, comprising a transformer casing and a cover fixedly installed on its top, wherein a plurality of heat sinks are fixedly installed on the bottom of the transformer casing, and a water cooling mechanism for cooling the transformer casing is provided on the side of the transformer casing; the water cooling mechanism includes a water storage tank fixedly connected to the transformer casing, the water storage tank containing sufficient cooling water, a return water pipe fixedly connected to the back of the water storage tank, one end of the return water pipe being connected to an S-shaped heat conduction pipe for cooling the transformer casing, the S-shaped heat conduction pipe being in close contact with the transformer casing, and one end of the S-shaped heat conduction pipe being connected to a U-shaped water inlet pipe, and an adjustment unit for further cooling the transformer casing being movably arranged between the U-shaped water inlet pipe and the front of the water storage tank.

[0009] A further technical improvement of the present invention is that: an air inlet pipe is fixedly connected to the bottom of the water storage tank, and a one-way valve is fixedly installed in the middle of the air inlet pipe. The opening direction of the one-way valve is the same as the direction in which external air enters the water storage tank. When the transformer is working normally, the extended end of the electric push rod is in its shortest state. By turning on the water pump, the cooling water in the water storage tank enters the S-shaped heat conduction pipe through the connecting pipe and the U-shaped water inlet pipe. The cooling water flowing in the S-shaped heat conduction pipe carries away the heat from the surface of the transformer shell, and then flows back to the water storage tank through the return water pipe, which assists several heat sinks in effectively cooling the transformer shell.

[0010] A further technical improvement of the present invention is that: the regulating unit includes a water pump fixedly installed on the front of the water storage tank, the water pump being model NKP-DC-S10B, with its input end connected to the bottom of the water storage tank, and its output end connected to a connecting pipe. An regulating pipe is movably inserted into the middle of the connecting pipe, and a through hole is opened in the middle of the regulating pipe, the opening of which faces the middle of several heat sinks. An atomizing nozzle is fixedly installed at the bottom of the regulating pipe, facing the bottom of several heat sinks. One end of the connecting pipe is connected to a U-shaped water inlet pipe, and a sealing ring is provided at the connection between the connecting pipe and the regulating pipe. When the transformer is operating under high load, it is electrically... As the extended end of the electric push rod extends to its longest position, the regulating tube moves downward. During this downward movement, a small amount of cooling water injected from the connecting pipe into the regulating tube is sprayed out through the through hole. The sprayed cooling water is applied to the center of several heat sinks. When the extended end of the electric push rod is at its longest position, the opening of the through hole is located inside the connecting pipe. A portion of the cooling water flowing in the connecting pipe flows into the regulating tube. Due to the water pressure, the cooling water in the regulating tube is atomized by the atomizing nozzle and sprayed onto the bottom of several heat sinks. Combined with the cooling water sprayed out through the through hole, this water-cooling effect on the heat sinks greatly improves the heat dissipation effect of the heat sinks on the transformer casing.

[0011] A further technical improvement of the present invention is that the diameter of the regulating tube is smaller than the inner diameter of the connecting tube.

[0012] A further technical improvement of the present invention is that a heat-conducting plate is fixedly embedded on the side of the water storage tank away from the transformer shell, and an electric push rod for driving the longitudinal movement of the regulating pipe is also fixedly installed on the front of the water storage tank; the cooling water in the water storage tank is cooled by the heat-conducting plate, thus ensuring the normal cooling effect of the cooling water on the transformer shell.

[0013] A further technical improvement of the present invention is that: a first limiting frame and a second limiting frame for limiting and guiding the adjusting pipe are fixedly installed on the water storage tank; the first limiting frame and the second limiting frame cooperate with each other to enable the adjusting pipe to move smoothly longitudinally.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] When the transformer is under high load, as the electric push rod extends to its longest position, the regulating pipe moves downward. During this downward movement, a small amount of cooling water injected from the connecting pipe is sprayed out through the through hole. This sprayed cooling water is applied to the center of several heat sinks. When the electric push rod is at its longest position, the opening of the through hole is located inside the connecting pipe. A portion of the cooling water flowing in the connecting pipe flows into the regulating pipe. Due to water pressure, the cooling water in the regulating pipe is atomized by the atomizing nozzle and sprayed onto the bottom of several heat sinks. This, combined with the cooling water sprayed through the through hole, provides water cooling to the heat sinks, greatly improving the heat dissipation effect of the heat sinks on the transformer casing.

[0016] When the transformer is in normal operation, the extended end of the electric push rod is in its shortest state. By turning on the water pump, the cooling water in the water tank enters the S-shaped heat conduction pipe through the connecting pipe and the U-shaped water inlet pipe. The cooling water flowing in the S-shaped heat conduction pipe carries away the heat from the surface of the transformer shell and then flows back to the water tank through the return pipe. This, along with several heat sinks, effectively cools the transformer shell. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-5 As shown, a nanocrystalline toroidal encapsulated transformer includes a transformer housing 3 and a cover 4 fixedly installed on its top. Several heat sinks 2 are fixedly installed on the bottom of the transformer housing 3, and a water cooling mechanism 1 for cooling the transformer housing 3 is provided on the side of the transformer housing 3.

[0026] Please see Figure 1 and Figure 2 As shown, the water cooling mechanism 1 includes a water storage tank 109 fixedly connected to the transformer housing 3. The water storage tank 109 contains a sufficient amount of cooling water. A return water pipe 108 is fixedly connected to the back of the water storage tank 109. One end of the return water pipe 108 is connected to an S-shaped heat conduction pipe 107 for cooling the transformer housing 3. The S-shaped heat conduction pipe 107 is in close contact with the transformer housing 3, and one end of the S-shaped heat conduction pipe 107 is connected to a U-shaped water inlet pipe 105. An adjustment unit 106 for further cooling the transformer housing 3 is movably arranged between the U-shaped water inlet pipe 105 and the front of the water storage tank 109.

[0027] Please see Figure 2As shown, the bottom of the aforementioned water storage tank 109 is fixedly connected to an air inlet pipe 103, and a one-way valve is fixedly installed in the middle of the air inlet pipe 103. The opening direction of the one-way valve is the same as the direction in which external air enters the water storage tank 109. When the transformer is working normally, the extended end of the electric push rod 102 is in its shortest state. By turning on the water pump 1062, the cooling water in the water storage tank 109 enters the S-shaped heat conduction pipe 107 through the connecting pipe 1064 and the U-shaped water inlet pipe 105. The cooling water flowing in the S-shaped heat conduction pipe 107 carries away the heat from the surface of the transformer shell 3, and then flows back to the water storage tank 109 through the return water pipe 108, which assists several heat sinks 2 in effectively cooling the transformer shell 3.

[0028] Please see Figures 2-4 As shown, the aforementioned regulating unit 106 includes a water pump 1062 fixedly installed on the front of the water storage tank 109. The water pump 1062 is model NKP-DC-S10B, and its input end is connected to the bottom of the water storage tank 109. The output end of the water pump 1062 is connected to a connecting pipe 1064. A regulating pipe 1063 is movably inserted into the middle of the connecting pipe 1064. A through hole 1065 is opened in the middle of the regulating pipe 1063, and the opening direction of the through hole 1065 faces the middle of several heat sinks 2. An atomizing nozzle is fixedly installed at the bottom end of the regulating pipe 1063, and the atomizing nozzle faces the bottom of several heat sinks 2. One end of the connecting pipe 1064 is connected to a U-shaped water inlet pipe 105, and a sealing ring 1066 is provided at the connection between the connecting pipe 1064 and the regulating pipe 1063. When the transformer is working under high load, the electric push rod 1... During the process of the extended end of 02 reaching its longest state, the regulating pipe 1063 moves downward. During the downward movement of the regulating pipe 1063, a small amount of cooling water injected from the connecting pipe 1064 into the regulating pipe 1063 will be sprayed out through the through hole 1065. The sprayed cooling water will spray onto the middle of several heat sinks 2. When the extended end of the electric push rod 102 is in its longest state, the opening of the through hole 1065 is located inside the connecting pipe 1064. A portion of the cooling water flowing in the connecting pipe 1064 will flow into the regulating pipe 1063. Due to the influence of water pressure, the cooling water in the regulating pipe 1063 is sprayed onto the bottom of several heat sinks 2 by the atomizing nozzle. Combined with the cooling water sprayed out through the through hole 1065, the cooling water of several heat sinks 2 is water-cooled, which will greatly improve the heat dissipation effect of several heat sinks 2 on the transformer shell 3.

[0029] Please see Figures 2-4 As shown, the diameter of the regulating pipe 1063 is smaller than the inner diameter of the connecting pipe 1064.

[0030] Please see Figure 2As shown, a heat-conducting plate 101 is fixedly embedded on the side of the water storage tank 109 away from the transformer shell 3, and an electric push rod 102 for driving the regulating pipe 1063 to move longitudinally is also fixedly installed on the front of the water storage tank 109; the cooling water in the water storage tank 109 is cooled by the heat-conducting plate 101, ensuring the normal cooling effect of the cooling water on the transformer shell 3.

[0031] Please see Figure 2 and Figure 3 As shown, a first limiting frame 1061 and a second limiting frame 104 for limiting and guiding the regulating pipe 1063 are fixedly installed on the water storage tank 109. The first limiting frame 1061 and the second limiting frame 104 cooperate with each other to enable the regulating pipe 1063 to move smoothly longitudinally.

[0032] Please see Figure 1 As shown, the transformer housing 3 has a support base made of nanocrystalline material inside. The support base has several fiberglass tubes 5, and the fiberglass tubes 5 are fixedly inserted through the cover 4.

[0033] Working Principle: In use, when the transformer is operating normally, the extended end of the electric push rod 102 is at its shortest position. By activating the water pump 1062, cooling water in the water storage tank 109 enters the S-shaped heat pipe 107 through the connecting pipe 1064 and the U-shaped inlet pipe 105. The cooling water flowing through the S-shaped heat pipe 107 carries away heat from the surface of the transformer casing 3 and then flows back to the water storage tank 109 through the return pipe 108, assisting several heat sinks 2 in effectively cooling the transformer casing 3. When the transformer is operating under high load, as the extended end of the electric push rod 102 extends to its longest position, the regulating pipe 1063 moves downwards. During the downward movement of the regulating pipe 1063... During the process, a small amount of cooling water injected into the regulating pipe 1063 from the connecting pipe 1064 will be sprayed out through the through hole 1065. The sprayed cooling water will be sprayed onto the middle of several heat sinks 2. When the extended end of the electric push rod 102 is in its longest state, the opening of the through hole 1065 is located inside the connecting pipe 1064. A portion of the cooling water flowing in the connecting pipe 1064 will flow into the regulating pipe 1063. Due to the influence of water pressure, the cooling water in the regulating pipe 1063 is sprayed onto the bottom of several heat sinks 2 by the atomizing nozzle. Combined with the cooling water sprayed out through the through hole 1065, the cooling water of several heat sinks 2 is water-cooled, which will greatly improve the heat dissipation effect of several heat sinks 2 on the transformer shell 3.
