Description

Technical Field

[0001] The invention belongs to the technical field of transformers, and in particular relates to an environmentally friendly flame-retardant power transformer. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are primary coil, secondary coil and iron core (magnetic core). Its main functions include voltage conversion, current conversion, impedance conversion, isolation and voltage stabilization (magnetic saturation transformer). A power transformer is a static electrical device that is mainly used to convert a certain value of AC voltage (current) into another or several different values ​​of voltage (current) with the same frequency.

[0003] The existing power transformer includes a transformer shell, a slide groove is provided in the transformer shell, a slider is provided in the slide groove for sliding, a support plate is fixed between the sliders, a winding structure is connected to the support plate, a connecting seat is fixed on the lower surface of the transformer shell, a through hole is provided on the connecting seat, a shock absorbing component is fixed on the inner surface of the transformer shell, the shock absorbing component is fixedly connected to the lower surface of the support plate, a heat dissipation component is connected to the transformer shell, the shock absorbing component weakens the vibration generated by the winding structure, and the heat dissipation component exchanges heat with a heat conducting plate fixed on the outer wall of the transformer by circulating water.

[0004] When the existing power transformer is dissipating heat, the heat dissipation component only exchanges heat with one side of the heat conductive plate, which results in a limited heat exchange area between the heat dissipation component and the heat conductive plate, and cannot achieve rapid heat dissipation of the heat conductive plate, which in turn causes the internal temperature of the transformer to be too high. The noise generated by vibration on the transformer not only includes the winding structure, but also the deviation caused by the installation of the transformer itself will cause vibration, thereby increasing the noise during the operation of the transformer.

[0005] Therefore, in view of the above situation, it is urgent to develop an environmentally friendly flame-retardant power transformer to overcome the shortcomings in current practical applications. Summary of the invention

[0050] A wind control module 5, which is arranged on the outer wall of the transformer body 1 and located at the upper and lower ends of the plate-type heat sink 6.

The drive control unit 52 is rotatably mounted on one side of the mounting sleeve 51. One end of the drive control unit 52 extends into the mounting sleeve 51 and is respectively connected to the transmission unit 53 and a group of wind control blades 54. The transmission unit 53 is rotatably mounted on the inner wall of the mounting sleeve 51. One end of the transmission unit 53 is connected to another group of wind control blades 54. The two groups of wind control blades 54 are both arranged on one side of the mounting sleeve 51 close to the plate-type heat sink 6, and the two groups of wind control blades 54 are coaxial.

[0051] like Figures 1 to 4 As shown, as a preferred embodiment of the present invention, the drive control unit 52 includes a rotating disk 521, a rotating shaft 522, a bracket 523 and a windward plate 524, the rotating disk 521 is rotatably installed on one side of the mounting sleeve 51, a rotating shaft 522 is fixed in the middle of the rotating disk 521, one end of the rotating shaft 522 extends into the mounting sleeve 51 and is respectively connected to the transmission unit 53 and a group of wind control blades 54, the other end of the rotating shaft 522 is installed with a bracket 523, and the bracket 523 is circumferentially distributed with windward plates 524.

[0052] like Figures 1 to 4As shown, as a preferred embodiment of the present invention, the transmission unit 53 includes a bevel gear A531, a bevel gear B532, a fixed sleeve 533, a bevel gear C534 and a rotating sleeve 535, the bevel gear A531 is fixed on the rotating shaft 522, the bevel gear B532 is rotatably mounted on the fixed sleeve 533, the fixed sleeve 533 is fixed on the inner wall of the mounting sleeve 51, one side of the bevel gear B532 is meshed with the bevel gear A531, and the other side of the bevel gear B532 is meshed with the bevel gear C534 rotatably mounted on the fixed sleeve 533, a rotating sleeve 535 is fixed on the inner wall of the bevel gear C534, and another group of wind control blades 54 is fixed on the outer wall of one end of the rotating sleeve 535.

[0053] like Figures 1 to 4 As shown, as a preferred embodiment of the present invention, the bevel gear A531, bevel gear C534, rotating sleeve 535, rotating shaft 522 and two groups of wind control blades 54 are all coaxial, and the inner diameters of the rotating sleeve 535 and the bevel gear C534 are larger than the outer diameter of the rotating shaft 522, so that the rotating shaft 522 can pass through the rotating sleeve 535 and the bevel gear C534 and be fixedly connected to a group of wind control blades 54, thereby realizing the coaxial reversal of the two groups of wind control blades 54.

[0054] In this embodiment, the external wind can drive the rotating shaft 522 to rotate through the windward plate 524 and the bracket 523, and the rotating shaft 522 simultaneously drives the bevel gear A531 and a group of wind control blades 54 to rotate, and the bevel gear A531 drives the bevel gear C534 to rotate through the bevel gear B532, and the bevel gear C534 drives another group of wind control blades 54 to rotate through the rotating sleeve 535. By utilizing the transmission characteristics of the bevel gears, the coaxial reversal of the two groups of wind control blades 54 is realized. The coaxial reversal of the two groups of wind control blades 54 can not only increase the airflow entering the plate-type radiator 6, but also increase the airflow discharged from the plate-type radiator 6. The coaxial reversal of the two groups of wind control blades 54 can reduce noise to a certain extent, reduce airflow turbulence and disturbance, provide a smoother airflow output, help improve the heat exchange efficiency of the plate-type radiator 6, and effectively extend the service life of the transformer.

[0055] For the fin-type radiator 6, when the wind control modules 5 arranged on both sides thereof blow air toward the inside at the same time, the air inside the fin-type radiator 6 will be convected, thereby accelerating the flow of air inside the fin-type radiator 6, thereby improving the heat exchange efficiency of the fin-type radiator 6; and when the two groups of wind control modules 5 blow air in the opposite direction away from the fin-type radiator 6 at the same time, that is, when the air carrying heat inside the fin-type radiator 6 is sucked, the circulation rate of the air around the fin-type radiator 6 can also be accelerated, thereby also improving the heat exchange efficiency of the fin-type radiator 6. Therefore, no matter how the external wind drives the wind control module 5 to work, that is, as long as the external wind can drive the wind control fan blades 54 to rotate, the circulation rate of the air around the fin-type radiator 6 can be accelerated, and the cooling effect of the entire transformer can be optimized, so that under different wind direction conditions, the heat dissipation system can still maintain efficient operation, ensuring that the transformer can operate at a relatively ideal temperature and extending its service life.

[0056] In a preferred embodiment, the drive control unit 52 may also adopt an electric control structure, that is, the rotating shaft 522 is driven to rotate by a motor, and the power source of the motor can be output by a transformer. However, when designing the electric control structure, it is necessary to use appropriate sound insulation and flame retardant materials to wrap the motor to reduce the noise generated during operation and meet the environmental protection and flame retardant characteristics of the transformer.

[0057] like Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, as a preferred embodiment of the present invention, the correction module 7 includes a connecting base plate 71, a connecting column 72, a correction seat 73 and a correction unit 74, the connecting base plate 71 is symmetrically fixed at both ends of the bottom of the transformer body 1, the connecting column 72 is fixed on the connecting base plate 71, one end of the connecting column 72 extends into the correction seat 73 and conflicts with the correction unit 74, one end of the correction seat 73 is installed on the fixed base frame 8, the other end of the correction seat 73 is installed on the base support 9, and the correction unit 74 is installed in the correction seat 73.

[0058] like Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, as a preferred embodiment of the present invention, the correcting seat 73 preferably adopts a split structure, which is mainly composed of two semicircular structures, and the two semicircular structures are connected to each other by fixing bolts, so that the correcting unit 74 and the connecting column 72 can be easily inserted therein, and the correcting seat 73 itself can be easily installed on the fixed base frame 8 and the base support 9.

[0059] like Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, as a preferred embodiment of the present invention, an arc groove 731 is opened on the inner wall of the bottom of the correcting seat 73, and the arc groove 731 is slidably matched with the spherical end 721 set at one end of the connecting column 72. When the correcting unit 74 corrects the connecting column 72, the spherical end 721 of the connecting column 72 can slide on the arc groove 731, which not only makes it convenient for the correcting unit 74 to quickly correct the connecting column 72, but also increases the contact area between the connecting column 72 and the correcting seat 73, thereby improving the installation stability of the transformer, and the inner wall of the bottom of the correcting seat 73 is circumferentially distributed around the arc groove 731 with sliding grooves 732 for installing the correcting unit 74.

[0060] like Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, as a preferred embodiment of the present invention, the correction unit 74 includes a fixing screw head 741, a control member 742, a correction member 743 and a spring 744, the fixing screw head 741 is fixed to one end of the control member 742, the other end of the control member 742 extends into the correction seat 73 and is slidably matched with the correction member 743, the outer wall of the other end of the control member 742 is threadedly matched with the inner wall of the correction seat 73, the correction member 743 is circumferentially distributed in the correction seat 73 along the connecting column 72, and the bottom of the correction member 743 is slidably installed in the sliding groove 732 and is connected to the spring 744 installed in the sliding groove 732, and the surfaces of the correction member 743 and the control member 742 that contact each other are both set as inclined surfaces;

[0061] The fixing screw head 741 and the control member 742 are both provided with through holes in the middle thereof for the connecting column 72 to pass through, and the diameter of the through hole is larger than the outer diameter of the deviation correcting member 743 .

[0062] In this embodiment, in order to correct the installation deviation between the transformer body 1 and the two groups of fixed base frames 8, the fixed screw head 741 is rotated by a wrench, and the fixed screw head 741 drives the control member 742 to rotate and move toward the correction seat 73. The control member 742 can drive the circumferentially distributed correction members 743 to gather in the direction close to the connecting column 72 by moving. Through the coordinated movement of multiple groups of correction members 743, the connecting column 72 can be adjusted in an inclined state until it is perpendicular to the fixed base frame 8. In this way, not only can the installation deviation between the two groups of fixed base frames 8 and the transformer body 1 be effectively corrected, ensuring the correct alignment between the two, reducing swing and vibration during operation, thereby reducing noise caused by vibration, and improving the running stability of the transformer, but also the center of gravity of the transformer body 1 can be maintained at the center position of the two groups of fixed base frames 8, which helps to maintain the balance of the equipment, reduce stress concentration or uneven load distribution caused by the offset of the center of gravity, effectively control and reduce the vibration and noise generated during the operation of the transformer, and improve the operating efficiency and environmental adaptability of the transformer.

[0063] In a preferred embodiment, the control member 742 preferably adopts an annular block structure;

[0064] The deflection-correcting member 743 preferably adopts an arc-shaped block structure.

[0065] like Figures 1 to 7 As shown, as a preferred embodiment of the present invention, in order to achieve the flame retardant and environmental protection functions of the transformer, the following aspects can be set:

[0066] In terms of functional design: for the lines inside or outside the transformer body 1, enhanced insulating materials can be used, which can effectively prevent fires caused by insulation aging; for the coils inside the transformer body 1, a continuous coil layout can be used, which can effectively enhance its heat dissipation performance, thereby reducing the risk of fire, and to a certain extent, can also achieve the flame retardant function; and through the external wind control module 5, as long as there is external wind, it can accelerate the circulation rate of air around the plate heat sink 6, optimize the cooling effect of the entire transformer, ensure that the heat dissipation system can operate efficiently and continuously, ensure that the transformer can work at a relatively ideal temperature, and also achieve the flame retardant function of the transformer;

[0067] The power of the wind control module 5 comes from the external wind, which avoids the power consumption required by traditional electric fans, thereby directly reducing the demand for energy and reducing the carbon emissions related to power production. Since wind power is a free and renewable energy source, the use of the wind control module 5 can significantly reduce long-term operating costs, especially in windy areas. Therefore, the design of the wind control module 5 can not only improve energy efficiency and reduce energy consumption, but also help reduce environmental pollution and the impact of climate change, and realize the environmental protection function of the transformer;

[0068] 2. Material selection: A layer of coating with good fire resistance is applied to both the inner and outer sides of the transformer body 1 and the transformer cover 2, and the connection between the two is sealed with a sealing strip with good sealing and fire resistance, so that it can prevent external fire from entering the transformer body 1, and the surface of the transformer body 1 and the transformer cover 2 can also be attached with a material that can intelligently change color at high temperature. When a fire occurs inside the transformer body 1 or the internal temperature is too high, the color change of the color-changing material attached to the surface can be used to achieve early warning of the fire, helping to take timely measures to control the fire;

[0069] 3. In terms of structural design: a blocking structure can be set inside the transformer. The blocking structure can block the transformer power supply when the transformer catches fire, including high and low voltage side switches, to prevent the current from continuing to flow through the transformer, reducing further thermal damage and electrical risks. At the same time, other equipment or systems connected to the transformer can also be installed and isolated to prevent the fire from spreading. The blocking structure can include circuit breakers, fuses, load switches, disconnectors, relays, differential protection devices, distance protection devices, and directional protection devices;

[0070] For oil-immersed transformers, an emergency control structure can be set at the position of the oil drain valve at the bottom. When the oil-immersed transformer catches fire and the oil on it overflows, the emergency control structure can quickly open the oil drain valve so that the oil on the transformer can be discharged to a safe area as soon as possible, thereby reducing the fire. The emergency control structure is mainly composed of a manual or electric oil drain valve, a remote control panel, a temperature sensor or a smoke detector, a control system and an intelligent analysis system.

[0071] Working principle of the present invention:

[0072] The external wind can drive the rotating shaft 522 to rotate through the windward plate 524 and the bracket 523. The rotating shaft 522 drives the bevel gear A531 and a group of wind control blades 54 to rotate at the same time. The bevel gear A531 drives the bevel gear C534 to rotate through the bevel gear B532. The bevel gear C534 drives another group of wind control blades 54 to rotate through the rotating sleeve 535. By utilizing the transmission characteristics of the bevel gears, the coaxial reversal of the two groups of wind control blades 54 is achieved. The coaxial reversal of the two groups of wind control blades 54 can not only increase the airflow entering the plate-type radiator 6, but also increase the airflow discharged from the plate-type radiator 6. The coaxial reversal of the two groups of wind control blades 54 can reduce noise to a certain extent, reduce airflow turbulence and disturbance, provide a smoother airflow output, help improve the heat exchange efficiency of the plate-type radiator 6, and effectively extend the service life of the transformer.

[0073] For the fin-type radiator 6, when the wind control modules 5 arranged on both sides thereof blow air toward the inside at the same time, the air inside the fin-type radiator 6 will be convected, so that the air inside the fin-type radiator 6 will flow faster, thereby improving the heat exchange efficiency of the fin-type radiator 6; and when the two groups of wind control modules 5 blow air in the opposite direction away from the fin-type radiator 6 at the same time, that is, when the air carrying heat inside the fin-type radiator 6 is sucked, the circulation rate of the air around the fin-type radiator 6 can also be accelerated, thereby improving the heat exchange efficiency of the fin-type radiator 6. Therefore, no matter how the external wind drives the wind control module 5 to work, that is, as long as the external wind can drive the wind control fan blades 54 to rotate, the circulation rate of the air around the fin-type radiator 6 can be accelerated, and the cooling effect of the entire transformer can be optimized, so that under different wind direction conditions, the heat dissipation system can still maintain efficient operation, ensuring that the transformer can operate at a relatively ideal temperature and extending its service life;

[0074] In order to correct the installation deviation between the transformer body 1 and the two groups of fixed base frames 8, the fixing screw head 741 is rotated with a wrench, and the fixing screw head 741 drives the control member 742 to rotate and move toward the correction seat 73. The control member 742 can drive the circumferentially distributed correction members 743 to gather in the direction close to the connecting column 72 by moving. Through the coordinated movement of multiple groups of correction members 743, the connecting column 72 can be adjusted in an inclined state until it is perpendicular to the fixed base frame 8. This not only allows the installation deviation between the two groups of fixed base frames 8 and the transformer body 1 to be effectively corrected, ensuring the correct alignment between the two, reducing swing and vibration during operation, thereby reducing noise caused by vibration, and improving the running stability of the transformer, but also can keep the center of gravity of the transformer body 1 at the center position of the two groups of fixed base frames 8, which helps to maintain the balance of the equipment, reduce stress concentration or uneven load distribution caused by the offset of the center of gravity, effectively control and reduce the vibration and noise generated during the operation of the transformer, and improve the operating efficiency and environmental adaptability of the transformer.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
