Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation, and in particular to an intelligent temperature-controlled transformer for wind power generation. Background Art

[0002] Wind power transformers are key equipment for voltage conversion, electrical isolation and energy transmission in wind power systems. Wind power generation mostly uses oil-immersed transformers, which are often used in offshore wind power and some large onshore wind farms with high requirements for stability and heat dissipation. They have reliable insulation performance and strong overload capacity, and can adapt to long-term stable operation in harsh environments such as offshore wind power. They use high and low voltage coil winding types, excellent mechanical properties, and an internal top-down integral frame structure, which can effectively avoid vibration resonance of the cabin. When the primary coil in the transformer is connected to an AC power supply, the alternating current will generate an alternating magnetic field in the primary coil, and this alternating magnetic field will be transmitted to the secondary coil through the iron core. According to the law of electromagnetic induction, when the magnetic flux passing through the secondary coil changes, an induced electromotive force will be generated in the secondary coil. If the secondary coil is in a closed loop, an induced current will be generated, thereby realizing the transfer of electrical energy from the primary coil to the secondary coil.

[0003] From the perspective of existing technology, common transformers use heat sinks to dissipate heat inside the transformer. Using heat sinks alone for heat dissipation has low heat dissipation efficiency and cannot be controlled, resulting in excessive internal temperature and pressure. When the pressure is too high, a pressure relief valve is usually used to relieve the pressure. The high-temperature gas discharged from the pressure relief has a high discharge temperature, which can easily cause harm to maintenance personnel. In addition, wind power transformers are often installed inside wind turbine cabins, with poor ventilation and heat that cannot be discharged well. The few substations are installed outside the wind turbine cabin. Transformers installed outside the wind turbine cabin are difficult to maintain and are located at high altitudes, making maintenance difficult. For this reason, we propose an intelligent temperature-controlled transformer for wind power generation. Summary of the invention

[0015] In summary, the technical effects and advantages of the present invention are as follows: 1. In the present invention, the heat dissipation of the transformer is carried out by the heat sinks on both sides of the transformer, and the heat sinks are supported by the pipe bracket. Since the pipe bracket is connected to the inside of the transformer and the heat sinks are inserted inside the pipe bracket, the heat sink is used to transfer the temperature inside the pipe bracket to the outside for heat dissipation, and the air supply fan on one side of the heat sink is used to transport the air into the gaps between the heat sinks, and the exhaust fan is used to suck out the air inside the heat sink, thereby increasing the flow rate of the air between the heat sinks and accelerating the heat dissipation efficiency.

[0016] 2. In the present invention, a temperature control component is used to detect the internal temperature of the transformer, and the temperature control component is used to control the exhaust fan, the air supply fan, the drive motor and the water pump to control the temperature of the transformer.

[0019] 5. In the present invention, the high-temperature and high-pressure gas generated inside the transformer is released through the pressure relief port opened on the surface of the transformer. When the pressure is too high, the pressure cap is lifted up to drive the touch rod close to the alarm device. When the trigger rod triggers the alarm device to alarm, it reminds the staff that the transformer is overloaded.

A heat exchanger is installed in the middle position of the gas pipe to cool the gas pipe, so that the temperature of the air discharged from the gas pipe is low. The air is discharged into the cooling pipe along the gas hole in the surrounding groove and mixed with the high-temperature and high-pressure gas, so that the temperature of the gas discharged from the exhaust pipe is rapidly reduced.

Since the drive wheel 16 is meshed with the driven wheel 23, and the driven wheel 23 is fixedly connected to the cross bar 14, the drive motor 17 drives the cross bar 14 to rotate. The two ends of the cross bar 14 are provided with thread grooves 15, and the thread grooves 15 are meshed with the gears 13. The rotation of the two sets of gears 13 drives the two sets of threaded rods 9 to rotate. A slider 10 is sleeved on the rod 9, and the slider 10 is slidably connected to the inside of the guide rail 8, so that the threaded rod 9 rotates to drive the slider 10 to move, and the movement of the slider 10 drives the nozzle 12 to slide, and the nozzle on the nozzle 12 sprays water to the heat sink 3 to accelerate heat dissipation. A water pump 20 is placed in the collection tank, and the water is guided to the nozzle 12 position through the water pipe 19 for spraying, thereby further improving the heat dissipation efficiency; the collection pool 6 is filled with water, and the water in the collection pool 6 is guided to the nozzle 12 position for spraying through the water pump 20, and the sprayed water flows along the heat sink 3 The dripping water is collected and recycled by utilizing the inclined structure of the guide plate 29. One side of the wind turbine cabin 28 is slidably connected with a shell 24, which is placed on the outside of the transformer 1 and the collection tank 6 to protect the transformer 1. The transformer 1 is placed on the outside of the wind turbine cabin 28 as a whole to improve the overall heat dissipation. Since the transformer 1 is placed in the wind turbine cabin 28 to affect the maintenance, the electric telescopic rod 30 is used to drive the driving frame 25 to slide, and the driving frame 25 is slidably connected to the sliding rod 27, so that the shell 24 slides into the maintenance cabin 31 to facilitate the maintenance of the transformer 1.

[0029] The high-temperature and high-pressure gas generated inside the transformer 1 is released through the pressure relief port 35 opened on the surface of the transformer 1. When the pressure is too high, the pressure cap 36 is lifted up, driving the touch rod to approach the alarm device 34. When the trigger rod 37 triggers the alarm device 34 to alarm, it reminds the staff that the transformer 1 is overloaded. When the pressure cap 36 is lifted up, the gas is discharged from the exhaust hole on the buffer sleeve 39 and discharged through the exhaust pipe 40. A cooling pipe 44 is installed inside the exhaust pipe 40. While the gas flows to the cooling pipe 44, the air bag 41 works, and the compressed air is discharged from the gas pipe 42 to the position of the surrounding groove 46. A heat exchanger 43 is installed in the middle position of the gas pipe 42 to cool the gas pipe 42, so that the temperature of the air discharged from the gas pipe 42 is low. The air is discharged into the cooling pipe 44 along the gas hole 45 in the surrounding groove 46, and mixed with the high-temperature and high-pressure gas, so that the temperature of the gas discharged from the exhaust pipe 40 is rapidly reduced.
