A low-loss superconducting transformer arrangement

Abstract

This invention discloses a low-loss superconducting transformer device, comprising an internal transformer unit with a coil inside, and including a cooling mechanism, a ventilation mechanism, and an alarm mechanism. The cooling mechanism is used to reduce the temperature of the internal transformer unit and is located outside the internal transformer unit. The ventilation mechanism is used to ventilate the cooling mechanism and is located on top of the cooling mechanism. Activating the cooling mechanism lowers the temperature inside the internal transformer unit, allowing the superconducting material used in the internal transformer unit to operate normally, thereby reducing energy loss. The ventilation mechanism ensures sufficient air inside the alarm mechanism. When the cooling mechanism malfunctions, liquid nitrogen leaks, liquefying the surrounding air.

Description

Technical Field

[0001] This invention relates to transformers. 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. The main functions of a transformer include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization. Based on their application, transformers can be divided into power transformers and special-purpose transformers. Transformers are fundamental equipment for power transmission and distribution, and are widely used in industry, agriculture, transportation, and urban communities.

[0003] Modern transformers typically use copper or silver core coils. However, during long-term operation, the energy loss during transmission is still significant, and a large amount of heat is generated, posing a fire hazard. Using coils made of superconducting materials can greatly reduce energy loss during transmission. However, this presents a problem: the transformer temperature needs to be kept low. Otherwise, the superconducting material cannot achieve its near-zero resistance physical function. Therefore, cooling the transformer is necessary. Summary of the Invention

[0004] The purpose of this invention is to overcome the drawback of large power loss in transformers and provide a low-loss superconducting transformer device.

[0005] The technical solution to achieve the above objective is: a low-loss superconducting transformer device, including a transformer built-in device, wherein a coil is provided inside the transformer built-in device, and a cooling mechanism, a ventilation mechanism and an alarm mechanism are included.

[0006] A cooling mechanism is provided to reduce the temperature of the transformer's internal components, and the cooling mechanism is located outside the transformer's internal components.

[0007] A ventilation mechanism is used to ventilate the cooling mechanism, and the ventilation mechanism is mounted on the cooling mechanism.

[0008] An alarm mechanism is provided to alert the cooling mechanism of a malfunction, and the alarm mechanism is located at the bottom of the cooling mechanism.

[0009] Preferably, the cooling mechanism includes a transformer oil tank, a cooling box, connecting plates, an outer shell, a liquid nitrogen generator, and a solar panel. The transformer oil tank is connected to the bottom of the outer wall of the transformer's internal device. The cooling box is connected to the bottom of the transformer oil tank. Multiple connecting plates are connected to the outer wall of the cooling box. The outer shell is connected to the outer wall of the connecting plates. Sealing plates are provided at the top and bottom of the transformer oil tank and the cooling box. A U-shaped sealing block is provided at the top of the outer shell. A liquid nitrogen generator is provided on the outer wall of the cooling box. A solar panel is provided on the outer wall of the outer shell. The solar panel and the liquid nitrogen generator are electrically connected. The output end of the liquid nitrogen generator is connected to the inside of the cooling box.

[0010] Preferably, the ventilation mechanism includes a ventilation pipe, a base plate, a baffle, a support spring, a round rod, a support plate, an absorbent sponge, a connecting rod, and a fixed plate. The ventilation pipe is inserted into the upper end of the outer shell, and one end of the ventilation pipe communicates with the space between the outer shell and the cooling box. The inner wall of the ventilation pipe is connected to the base plate. The upper end of the base plate is connected to the support spring, and the upper end of the support spring is connected to the support plate. The bottom end of the support plate is connected to the round rod, and the bottom end of the round rod penetrates the base plate. An absorbent sponge is placed on the upper end of the support plate. The top end of the support plate is connected to the connecting rod, and the outer wall of the connecting rod penetrates the absorbent sponge. The upper end of the connecting rod is connected to the fixed plate, and the bottom end of the fixed plate is in contact with the top end of the absorbent sponge.

[0011] Preferably, the alarm mechanism includes a receiver box, a receiver tube, an alarm, a carrier plate, a guide rod, a return spring, a partition, a conductive block, and electrical contacts. The receiver box is connected to the bottom end of the outer shell, and the receiver box communicates with the space between the outer shell and the cooling box. A partition is connected to the inner wall of the receiver tube, a return spring is connected to the upper end of the partition, a carrier plate is connected to the upper end of the return spring, a guide rod is connected to the bottom end of the carrier plate, the bottom end of the guide rod passes through the partition, a conductive block is connected to the bottom surface of the guide rod, and two symmetrically distributed electrical contacts are provided on the inner wall of the bottom end of the receiver tube. The electrical contacts are electrically connected to the alarm.

[0012] Preferably, the solar panel is equipped with a storage battery, and the transformer tank, cooling box, connecting plate and outer casing are all made of metal steel.

[0013] Preferably, the vent pipe includes a U-shaped pipe and an L-shaped pipe, one end of the U-shaped pipe is connected to the top of the outer shell, the bottom end of the U-shaped pipe is connected to the L-shaped pipe, and the base plate is located inside the U-shaped pipe.

[0014] Preferably, the receiving box is square-shaped, the receiving tube is connected to the receiving box, and a sealing plate is connected to the bottom end of the receiving tube.

[0015] The beneficial effects of this invention are:

[0016] 1. Activate the cooling mechanism to reduce the temperature inside the transformer's internal components, ensuring the normal operation of the superconducting materials used in the internal components and thus reducing energy loss. Utilize the ventilation mechanism to ensure sufficient air inside the alarm mechanism. When the cooling mechanism malfunctions, liquid nitrogen leakage will liquefy the surrounding air, and the resulting water will activate the alarm mechanism, alerting personnel to the leak in the cooling mechanism.

[0017] 2. When the air is relatively dry, air can pass through the absorbent sponge to ensure the air content inside the casing. When there is a humid airflow, the humid airflow will enter the vent pipe, and the moisture in the humid airflow will be absorbed by the absorbent sponge, preventing the humid airflow from carrying a large amount of water vapor into the casing and then into the receiver box, which could cause a false alarm. When the absorbent sponge absorbs a lot of water, the absorbent sponge will press down on the support plate, causing the support plate to press down on the support spring and the round rod. At the same time, the support plate will also drive the fixed plate to move downward through the connecting rod. When the support plate passes the baffle, the absorbent sponge will be squeezed by the fixed plate and the baffle, causing the absorbent sponge to squeeze out some water. The support spring will push the support plate upward, and then the water will be discharged from the vent pipe, thus ensuring that the absorbent sponge can be used continuously.

[0018] 3. When liquid nitrogen leaks from the cooling chamber, the air moisture in the space between the cooling chamber and the outer shell will liquefy, causing the water to fall onto the carrier plate. The carrier plate will then press down on the guide rod and the return spring, causing the conductive block to contact the two electrical contacts, thus connecting the circuit and triggering the alarm to alert personnel of the liquid nitrogen leak.

[0028] The invention will now be further described with reference to the accompanying drawings.

[0029] Reference Appendix Figure 1-7 A low-loss superconducting transformer device includes a transformer built-in device 1, a coil is installed inside the transformer built-in device 1, and a cooling mechanism 2, a ventilation mechanism 3 and an alarm mechanism 4.

[0030] Cooling mechanism 2 is used to reduce the temperature of transformer internal device 1. Cooling mechanism 2 is located outside transformer internal device 1.

[0031] Ventilation mechanism 3 is used to ventilate and cool the cooling mechanism 2, and the ventilation mechanism 3 is installed on the cooling mechanism 2;

[0032] Alarm mechanism 4 is used to alert the cooling mechanism 2 to malfunction, and alarm mechanism 4 is located at the bottom of cooling mechanism 2.

[0033] A controller is set up and electrically connected to the cooling mechanism 2. The transformer's built-in device 1 is made of superconducting material. The cooling mechanism 2 is activated to reduce the temperature inside the transformer's built-in device 1, so that the superconducting material in the transformer's built-in device 1 can operate normally, thereby reducing the energy loss of the transformer's built-in device 1. The ventilation mechanism 3 is used to ensure that there is enough air inside the alarm mechanism 4. When the cooling mechanism 2 malfunctions, liquid nitrogen leaks, which will liquefy the surrounding air. The water formed will activate the alarm mechanism 4, thereby alerting personnel that the cooling mechanism 2 has leaked.

[0034] Reference Appendix Figure 2-4 The cooling mechanism 2 includes a transformer oil tank 201, a cooling box 202, connecting plates 203, a shell 204, a liquid nitrogen generator 205, and a solar panel 206. The transformer oil tank 201 is connected to the bottom of the outer wall of the transformer internal device 1. The cooling box 202 is connected to the bottom of the transformer oil tank 201. Multiple connecting plates 203 are connected to the outer wall of the cooling box 202. The shell 204 is connected to the outer wall of the connecting plates 203. The top and bottom of the transformer oil tank 201 and the cooling box 202 are... A sealing plate is provided, and a U-shaped sealing block is provided at the top of the outer shell 204. A liquid nitrogen generator 205 is provided on the outer wall of the cooling box 202, and a solar panel 206 is provided on the outer wall of the outer shell 204. The solar panel 206 is electrically connected to the liquid nitrogen generator 205. The output end of the liquid nitrogen generator 205 is connected to the inside of the cooling box 202. A storage battery is provided on the solar panel 206. The transformer oil tank 201, the cooling box 202, the connecting plate 203 and the outer shell 204 are all made of metal steel.

[0035] Cooling oil is injected into the transformer oil tank 201. The solar panel 206 supplies power to the liquid nitrogen generator 205, which generates liquid nitrogen that is input into the cooling box 202. Since the transformer oil tank 201, cooling box 202, connecting plate 203 and outer shell 204 are all made of metal steel, the transformer oil tank 201 conducts heat into the cooling box 202, thereby cooling the transformer's internal device 1.

[0036] Reference Appendix Figure 2-6The ventilation mechanism 3 includes a ventilation pipe 301, a base plate 302, a baffle 303, a support spring 304, a round rod 305, a support plate 306, an absorbent sponge 307, a connecting rod 308, and a fixed plate 309. The ventilation pipe 301 is inserted into the upper end of the outer shell 204. The ventilation pipe 301 includes a U-shaped pipe and an L-shaped pipe. One end of the U-shaped pipe is connected to the outer shell 204. The top end of the U-shaped tube is connected to the bottom end of the L-shaped tube. The bottom plate 302 is located inside the U-shaped tube. One end of the vent pipe 301 is connected to the gap between the outer shell 204 and the cooling box 202. The inner wall of the vent pipe 301 is connected to the bottom plate 302. The upper end of the bottom plate 302 is connected to the support spring 304. The upper end of the support spring 304 is connected to the support plate 306. The bottom end of the support plate 306 is connected to the round rod 305. The bottom end of the round rod 305 passes through the bottom plate 302. The upper end of the support plate 306 is placed with a water-absorbing sponge 307. The top end of the support plate 306 is connected to the connecting rod 308. The outer wall of the connecting rod 308 passes through the water-absorbing sponge 307. The upper end of the connecting rod 308 is connected to the fixed plate 309. The bottom end of the fixed plate 309 is in contact with the top end of the water-absorbing sponge 307.

[0037] When the air is relatively dry, air can pass through the absorbent sponge 307 to ensure the air content inside the outer casing 204. When there is a humid airflow, the humid airflow will enter the vent pipe 301, and the moisture in the humid airflow will be absorbed by the absorbent sponge 307, preventing the humid airflow from carrying a large amount of water vapor into the outer casing 204 and then into the receiver box 401, causing a false triggering of the alarm mechanism 4. When the absorbent sponge 307 absorbs a large amount of moisture, the absorbent sponge 307 will press down on the support plate 306, causing the support plate 306 to press down on the support spring 304 and the round rod 305. Simultaneously, the connecting rod 308 drives the fixed plate 309 to move downward. When the support plate 306 passes the baffle 303, the water-absorbing sponge 307 will be squeezed by the fixed plate 309 and the baffle 303, causing the water-absorbing sponge 307 to squeeze out some water. The support spring 304 will push the support plate 306 upward, and then discharge it from the vent pipe 301, thereby ensuring that the water-absorbing sponge 307 can be used continuously.

[0038] Reference Appendix Figure 2-6The alarm mechanism 4 includes a receiver box 401, a receiver tube 402, an alarm 403, a carrier plate 404, a guide rod 405, a reset spring 406, a partition 407, a conductive block 408, and an electrical contact 409, and a housing 204. The bottom end of the receiver tube 402 is connected to a receiving box 401, which is square and truncated. The receiving tube 402 is connected to the receiving box 401. The bottom end of the receiving tube 402 is connected to a sealing plate. The receiving box 401 is connected to the gap between the outer shell 204 and the cooling box 202. The inner wall of the receiving tube 402 is connected to a partition 407. The upper end of the partition 407 is connected to a return spring 406. The upper end of the return spring 406 is connected to a carrier plate 404. A sealing ring is sleeved on the outer side of the carrier plate 404. The bottom end of the carrier plate 404 is connected to a guide rod 405. The bottom end of the guide rod 405 passes through the partition 407. The bottom surface of the guide rod 405 is connected to a conductive block 408. The inner wall of the bottom end of the receiving tube 402 is provided with two symmetrically distributed electrical contacts 409. The electrical contacts 409 are electrically connected to the alarm 403.

[0039] When liquid nitrogen leaks from the cooling chamber 202, the air moisture in the space between the cooling chamber 202 and the outer shell 204 will liquefy, causing water to fall onto the carrier plate 404. The carrier plate 404 will then press down on the guide rod 405 and the return spring 406, causing the conductive block 408 to contact the two electrical contacts 409, thus connecting the circuit and triggering the alarm 403 to alert personnel of the liquid nitrogen leak.
