Description

Technical Field

[0001] The present invention relates to the technical field of power equipment, and particularly to a transformer housing with a noise reduction function. Background Art

[0002] After the transformer works for a long time, its internal components will emit a large amount of heat, which accumulates inside the transformer. To enable the normal operation of the transformer, ventilation and heat dissipation are required for the transformer.

[0003] The existing heat dissipation method is to control the fan to suck the external cold air into the housing through the ventilation holes on the transformer housing to dissipate heat from the transformer. The following problems exist in this method.

[0004] First, when the fan is working, it will generate a lot of noise. During the operation of the transformer, due to the change of the internal magnetic field, high-frequency jitter will continuously occur. During the jitter process, the connecting base will be driven to jitter, so the transformer will generate a lot of noise, and the noise generated by the fan and the transformer jitter will be directly transmitted to the outside through the ventilation holes. During the jitter process, the cables and fixing screws connected to the transformer will become loose.

[0005] Second, in the existing transformer, the external air is directly sucked into the housing by the fan to dissipate heat from the transformer. During this process, a large amount of dust and water vapor will enter the transformer through the ventilation holes. If the connection of the transformer cable becomes loose at this time, the dust and water vapor will enter the interface, which will cause a short circuit fault in the transformer.

[0006] Third, when the existing transformer works in places with a large amount of dust such as steel mills, the method of sucking the external air into the housing by the fan to dissipate heat from the transformer cannot block the dust from entering the transformer interior, and frequent maintenance is required to ensure the normal and stable operation of the transformer. At the same time, the power consumption in the steel mill is large, and the transformer needs to maintain long-term and high-efficiency operation, which will cause the temperature inside the transformer to rise rapidly. However, the heat dissipation method by the fan for the transformer has poor effect and cannot dissipate the heat in time, resulting in heat accumulation and making the transformer unable to work normally. Summary of the Invention

[0007] In order to overcome the disadvantages that the heat dissipation fan of the existing transformer will generate a lot of noise during operation, and during the operation of the transformer, due to the change of the internal magnetic field, high-frequency jitter will continuously occur. During the jitter process, the connecting base will be driven to jitter, so the transformer will generate a lot of noise, and the noise generated by the fan and the transformer jitter will be directly transmitted to the outside through the ventilation holes.

[0022] By setting two narrow ventilation slots in the present invention, compared with the existing transformer heat dissipation and exhaust device, the number and size of the exhaust ports are greatly reduced. And during the process of hot air discharge, the sound insulation board absorbs the noise brought by the hot air circulation, effectively reducing the generation and output of noise;

[0023] After the air inlet plate has undergone long-term ventilation operation, the wiper blade pushes the water collected at the water collection tank into the water pipe, and sprays it towards the air inlet plate through the water spraying slots of the water pipe. The water sprayed washes the dust at the ventilation holes of the air inlet plate clean, ensuring that the air inlet plate can work normally and stably. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] When a new transformer needs to be installed:

[0052] First, open the two safety doors of the housing 3, and control the telescopic part of the first electric push rod 101 to drive the connecting plate 102, the first ventilation pipe 103 and the top heat dissipation system to move upward, leaving a suitable space for installing the transformer equipment 001. Subsequently, install the transformer equipment 001 on the heat dissipation rack 2, so that the heat dissipation fins on the front, back, left and right four parts of the transformer equipment 001 correspond to the four rows of ventilation openings 2a on the heat dissipation rack 2. Then, screw the connector 002 onto the transformer equipment 001. At this time, the connector 002 is directly below the wind power ring 323. Then, control the telescopic part of the first electric push rod 101 to drive the connecting plate 102, the first ventilation pipe 103 and the top heat dissipation system to move downward. During this process, the upper half of the connector 002 will pass through the wind power ring 323. At this time, the middle part of the connector 002 is fixed by the wind power ring 323. Then, the cable 003 of the external power equipment passes through the hollow heat dissipation plate 301 and the movable disk 303 in sequence and is connected to the connector 002, and then close the two safety doors of the housing 3;

[0053] After the voltage transformation device 001 has been working for a period of time, a large amount of heat is dissipated inside the housing 3. At this time, the control air inlet plate 202a is opened to input the air outside the housing 3 into the housing 3, so that the outside air passes through the air inlet plate 202a and the hollow plate 202 in sequence and enters the air inlet box 201. In this process, the dust in the air is filtered out by the air inlet plate 202a first. Then, the air entering from the hollow plate 202 contacts the condensation part 201a, causing the relatively low-temperature condensation part 201a to condense with the outside air entering, condensing the moisture in the air into water droplets, which flow along the inclined direction of the condensation part 201a into the water collection tank 221 for storage. At the same time, the condensation part 201a reduces the temperature of the air in contact with it, making the outside air entering become low-temperature and dry air. Subsequently, most of the cold air in the air inlet box 201 is blown upward from the air outlet 201c and the ventilation opening 2a. This part of the cold air is continuously blown onto the heat sink with the highest temperature in the voltage transformation device 001 above, so that the heat sink of the voltage transformation device 001 is quickly cooled, achieving a significant heat dissipation effect.

[0054] In this way, the temperature of the air is reduced by the condensation part 201a in the air inlet box 201, and the moisture in the air is removed, so that the subsequent air in contact with each part of the voltage transformation device 001 is low-temperature and dry air, which will neither cause a circuit failure of the voltage transformation device 001 due to water vapor, and at the same time the low-temperature air can make the voltage transformation device 001 have a better cooling effect.

[0055] At the same time, a part of the low-temperature and dry air in the air inlet box 201 enters the bottom of the heat dissipation rack 2 through the air outlet groove 201b, thereby reducing the temperature of the bottom of the heat dissipation rack 2 and conducting it to the bottom of the voltage transformation device 001 through the heat dissipation rack 2, so that the temperature of the bottom of the voltage transformation device 001 is reduced, enabling the bottom of the voltage transformation device 001, which was originally difficult to dissipate heat, to also have a good heat dissipation effect. To prevent the air that has absorbed heat at the bottom of the heat dissipation rack 2 from accumulating all the time and causing heat accumulation, the low-temperature and dry air entering the bottom of the heat dissipation rack 2 from the air outlet groove 201b is guided towards the ventilation openings 2a on the left and right by the rhombic air guide block 211, which not only achieves the purpose of dissipating heat at the bottom of the heat dissipation rack 2, but also avoids the problem of heat accumulation at the bottom of the heat dissipation rack 2 due to the inability of air to circulate.

[0056] Meanwhile, a portion of the low-temperature dry air in the air inlet box 201 is successively conveyed through the second ventilation pipe 304 and the first ventilation pipe 103 to the heat dissipation area 301b of the hollow heat dissipation plate 301. When the heat dissipation area 301b is filled with low-temperature dry air, but the second ventilation pipe 304 and the first ventilation pipe 103 are still continuously conveying low-temperature dry air, at this time, the subsequently conveyed air will cause the air pressure in the heat dissipation area 301b to rise. Through this part of the air pressure, the movable plate 303 connected to the spring telescopic rod 302 is squeezed downward, separating from the hollow heat dissipation plate 301, so that a gap appears between the movable plate 303 and the lower part of the hollow heat dissipation plate 301. Thus, the low-temperature dry air can be conveyed from this gap to the lower part of the hollow heat dissipation plate 301, to the connection part of the higher-temperature joint 002 at the upper part of the voltage transformation device 001, and the higher-temperature joint 002 connection area at the upper part of the voltage transformation device 001 is cooled through this part of the air, achieving a good heat dissipation effect.

[0057] Meanwhile, the air passing through the gap between the movable plate 303 and the lower part of the hollow heat dissipation plate 301 flows downward, driving the wind power ring 323 to rotate. Through the rotation of the wind power ring 323, the joint 002 that is rotatably connected to the voltage transformation device 001 and has become loose is rotated tighter. This solves the problem that during the operation of the existing transformer, due to the change of the internal magnetic field, high-frequency jitter will continuously occur, and during the jitter process, the connection base will be driven to jitter, and the cables and fixing screws connected to the transformer will become loose.

[0058] The cold air blown upward from the air outlet 201c and the ventilation opening 2a continuously blows towards the heat dissipation fins with the highest temperature in the voltage transformation device 001, enabling the heat dissipation fins of the voltage transformation device 001 to quickly cool down, achieving a significant heat dissipation effect. When this part of the air blows to the top of the voltage transformation device 001 subsequently, it has absorbed a lot of heat and has changed from low-temperature dry air to hot air containing heat. To avoid the problem of heat accumulation at the top of the voltage transformation device 001, this part of the hot air will contact the outer ring inclined surface of the first air guide plate 312, and through the outer ring inclined surface of the first air guide plate 312, this part of the hot air is led to the ventilation slot 301a of the hollow heat dissipation plate 301. During this process, this part of the hot air will contact the sound insulation plate 305, and the sound insulation plate 305 will absorb the volume in this part of the hot air, reducing the noise generated when this part of the hot air is output.

[0059] Meanwhile, the air passing through the gap between the movable plate 303 and the lower part of the hollow heat dissipation plate 301 is led to the ventilation slot 301a of the hollow heat dissipation plate 301 by the inner ring inclined surface of the first air guide plate 312. The left and right ends of the first air guide plate 312 are blocked by the second air guide plate 313, so the hot air on the left and right sides can only be led to the ventilation slot 301a of the hollow heat dissipation plate 301 through the inner ring inclined surface of the first air guide plate 312 and the air outlet part 313a, achieving the purpose of heat dissipation.

[0060] In this way, only two narrow ventilation slots 301a are provided, which greatly reduces the number and size of the air outlets compared with the existing transformer heat dissipation and exhaust device. During the process of hot air discharge, the sound insulation board 305 absorbs the noise generated by the hot air flow, solving the problems that a large amount of noise is generated during the heat dissipation of the existing transformer, and during the operation of the transformer, due to the change of the internal magnetic field, high-frequency jitter will continue to occur. During the jitter process, the connecting base will be driven to jitter, so the transformer will generate a large amount of noise, and the noise generated by the jitter of the fan and the transformer will be directly transmitted to the outside through the ventilation holes.

[0061] It should be noted that after the air inlet plate 202a has undergone long-term ventilation operation, there will inevitably be a large amount of dust and other impurities in the ventilation holes of the air inlet plate 202a. To avoid blockage of the ventilation holes of the air inlet plate 202a or excessive dust, resulting in the air inlet plate 202a being unable to ensure that all dust can be filtered. At this time, stop the ventilation work of the air inlet plate 202a. Subsequently, control the telescopic part of the second electric push rod 224 to drive the wiper 225 to push towards the direction of the water collecting tank 221. The water collected at the water collecting tank 221 is pushed towards the water pipe 222 by the wiper 225 and sprayed towards the air inlet plate 202a through the spray slot 222a of the water pipe 222. The dust at the ventilation holes of the air inlet plate 202a is washed clean by the sprayed water, ensuring that the air inlet plate 202a can work normally and stably.
