Description

Technical Field

[0001] This utility model belongs to the field of transformer technology, and specifically refers to an American-style transformer with anti-condensation function. Background Technology

[0002] In modern power systems, American-style transformers are a commonly used power distribution device, widely applied in various power demand scenarios such as residential communities, commercial sites, and factories. They convert high-voltage electrical energy into low-voltage electrical energy suitable for user needs, playing an indispensable role in power distribution and supply, and providing stable and reliable power support for people's daily lives and industrial production.

[0003] However, traditional American-style transformers exhibit significant shortcomings in their anti-condensation capabilities during actual operation. The drying devices in traditional American-style transformers often use disposable desiccants, which cannot be recycled. Once the desiccant expires, it can no longer absorb moisture. Furthermore, the installation location of the drying devices is often fixed and singular, making it difficult to cover the entire internal space of the transformer, leaving some areas still at risk of condensation. Due to the inadequate design of the ventilation and drying systems in traditional American-style transformers, they cannot effectively cope with complex and changing environmental conditions, resulting in a significant reduction in anti-condensation effectiveness and failing to meet the ever-increasing demands for power reliability. Utility Model Content

[0004] The purpose of this invention is to provide an American-style transformer with anti-condensation function. Through the coordinated operation of the ventilation and drying mechanism and the diffusion mechanism, it effectively alleviates the problem that traditional American-style transformers are prone to condensation in complex environments, which leads to frequent short-circuit faults in electrical components and low operational reliability.

[0005] The purpose of this utility model is achieved as follows: an American-style transformer with anti-condensation function includes a body, an air intake mounting chamber connected to one side of the body, and an exhaust port connected to the other side of the body, and further includes:

[0006] A diffusion mechanism includes an exhaust fan located inside an exhaust port and a diffusion assembly located outside the exhaust port for diffusing the range of gas discharge.

[0007] The ventilation and drying mechanism includes an adjustable air intake guide plate located outside the air intake installation room, an air intake fan located inside the air intake installation room, a replaceable drying box located inside the air intake installation room for absorbing moisture, and a heating component located inside the air intake installation room for increasing the internal temperature of the machine body.

[0008] The present invention is further configured such that the adjustable air intake guide vane includes:

[0009] A flow guide frame is connected to the outside of the air intake mounting chamber;

[0010] The guide vanes are arranged obliquely in sequence along the longitudinal direction within the guide frame, and the guide vanes are rotatably connected to the guide frame via a rotating shaft;

[0011] An angle adjustment component is used to adjust the tilt angle of the guide vanes.

[0012] The present invention is further configured such that the angle adjustment component includes:

[0013] A connecting gear, which is connected to a rotating shaft and corresponds one-to-one with multiple rotating shafts, is disposed outside the flow guide frame, and the connecting gears mesh with each other;

[0014] A drive gear meshes with a connecting gear located at the bottom, and a drive motor for driving the drive gear to rotate is also provided outside the flow guide frame;

[0015] The drive chamber, located below the flow guide frame, is used to house the drive motor.

[0016] The present invention is further configured such that the replaceable drying box includes:

[0017] The housing is located inside the intake fan;

[0018] A movable guide rail is provided on the inner bottom surface of the air intake installation chamber, and a movable guide block that cooperates with the guide rail is provided at the bottom of the box body;

[0019] The handle is used to drive the box to move on the guide rail.

[0020] The present invention is further configured such that the heating assembly includes:

[0022] Heating wires are arranged longitudinally within a fixed frame;

[0023] A connecting sleeve is fitted onto both ends of each heating wire, and the connecting sleeve is connected to the fixed frame.

[0024] The present invention is further configured such that the diffusion component includes:

[0025] An exhaust section is located on the outside of the exhaust port, and the exhaust section has a funnel-shaped structure with the diameter gradually increasing from the inside to the outside.

[0026] The diffuser is connected to the outlet of the exhaust section, and the diffuser has a funnel-shaped structure similar to that of the exhaust section.

[0027] The present invention is further configured such that a filter plate is provided in the air intake installation chamber, and the filter plate is located between the adjustable air intake guide plate and the air intake fan.

[0028] The present invention is further configured such that a temperature sensor for real-time monitoring of the internal temperature of the machine body and a humidity sensor for measuring the air humidity are provided on the inner side of the filter plate.

[0029] By adopting the above technical solution, the beneficial effects that this utility model can achieve are:

[0039] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-5 :

[0040] Example 1:

[0041] This embodiment provides an American-style transformer with anti-condensation function, including a body 1, an air intake mounting chamber 2 connected to one side of the body 1, and an exhaust port 10 connected to the other side of the body 1, and further including:

[0042] The diffusion mechanism 3 includes an exhaust fan 30 disposed inside the exhaust port 10 and a diffusion component 31 disposed outside the exhaust port 10 for diffusing the gas discharge range;

[0043] The ventilation and drying mechanism 4 includes an adjustable air intake guide plate 40 located outside the air intake installation chamber 2, an air intake fan 41 located inside the air intake installation chamber 2, a replaceable drying box 42 located inside the air intake installation chamber 2 for absorbing moisture, and a heating component 43 located inside the air intake installation chamber 2 for increasing the internal temperature of the machine body 1.

[0044] The main body (body 1) serves as the core structure of an American-style transformer, providing installation space and protection for the various electrical components, ensuring the transformer's normal operation. Body 1 is typically a closed, box-like structure, often rectangular in shape, to house the internal electrical equipment and related components.

[0045] The air intake chamber 2 serves as the channel and processing space for air to enter the transformer, providing conditions for subsequent ventilation and drying. The air intake chamber 2 is generally a relatively independent chamber, connected to the main body 1, and is typically square in shape. The air intake chamber 2 and the main body 1 can be connected by welding or bolts, ensuring a secure and well-sealed connection.

[0046] The exhaust port 10 is used to discharge the gas inside the transformer and maintain the circulation and balance of internal air. The exhaust port 10 is usually an open structure, and its shape is generally circular or square.

[0047] The diffusion mechanism 3 is used to enable the gas discharged from the transformer to exchange better with the outside air, allowing the hot air or moisture inside the body 1 to be discharged into a larger space in a timely manner, maintaining the air circulation and renewal inside the body 1, and preventing the gas from accumulating in a local area.

[0048] The exhaust fan 30 provides suction power to extract gas from the transformer, promoting airflow and achieving ventilation to prevent moisture buildup inside the transformer. The exhaust fan 30 mainly consists of a motor and fan blades. The motor is the power source, driving the fan blades to rotate. The fan blades are generally radial, commonly with three or more blades, while the motor is usually cylindrical. The motor can be fixedly connected to the inner wall of the exhaust port 10 via a bracket, and the fan blades are mounted on the motor's output shaft and driven to rotate by the motor.

[0049] The diffuser assembly 31 allows the gas discharged from the American transformer to diffuse to a larger spatial area, avoiding the gas from being concentrated in a small area, which is conducive to better mixing and exchange between the surrounding air and the discharged gas.

[0050] The ventilation and drying mechanism 4 effectively reduces the humidity inside the transformer 1 by introducing relatively dry outside air and expelling the humid air inside. This lowers the dew point temperature of the air, preventing water vapor from condensing into condensation at low temperatures. While expelling moisture, it also regulates the internal temperature of the transformer. Proper ventilation removes excess heat, preventing condensation caused by excessively high or low temperatures, maintaining a stable internal temperature, and ensuring the transformer operates in a suitable environment.

[0051] The adjustable air intake baffle 40 can control the amount of air entering the transformer by adjusting its own state. According to the actual operating needs of the transformer, the amount of air intake can be flexibly adjusted to achieve a suitable ventilation and heat dissipation effect.

[0052] The guide frame 400 serves as the basic support structure for the entire adjustable intake guide vane 40, supporting the guide vanes 401 and securely connected to the intake mounting chamber 2, guiding outside air into the intake mounting chamber 2. The guide frame 400 is a frame assembled from multiple frames, forming a regular space inside for installing the guide vanes 401. The guide frame 400 is typically rectangular, adapting to the shape of the outer opening of the intake mounting chamber 2, ensuring a tight connection and smooth air guidance. The guide frame 400 can be firmly connected to the intake mounting chamber 2 via bolts or welding.

[0053] The guide vanes 401 precisely control the airflow and direction entering the air intake installation chamber 2 by changing their tilt angle. They can flexibly adjust the air intake state under different ambient humidity, temperature, and transformer operating conditions to achieve optimal ventilation and drying effects. The guide vanes 401 are typically thin-plate structures with a rotating shaft 402 at one end for rotatable connection to the guide frame 400. They are generally elongated strips, arranged longitudinally and obliquely within the guide frame 400, maintaining a certain spacing between the vanes to ensure airflow and facilitate angle adjustment. The guide vanes 401 are rotatably connected to the guide frame 400 via the rotating shaft 402, which is fixed integrally with the guide vanes 401. Both ends of the rotating shaft 402 are installed in corresponding shaft holes in the guide frame 400, enabling flexible rotation of the vanes.

[0054] The angle adjustment component 403 optimizes the airflow direction and velocity entering the American transformer by changing the angle of the guide vane 401, so that the air can flow more rationally inside the transformer, improve the ventilation and drying effect, and better achieve the anti-condensation function.

[0055] The connecting gear 4030 is used to transmit power, converting the rotation of the drive gear 4031 into the synchronous rotation of each guide vane 401, thereby achieving the purpose of synchronously adjusting the tilt angle of the guide vanes 401. The connecting gear 4030 can be a standard gear structure with evenly distributed teeth and a central shaft hole for tight connection with the rotating shaft 402 of the guide vanes 401. The connecting gear 4030 can also be tightly connected to the rotating shaft 402 via a key.

[0056] The drive gear 4031 meshes with the connecting gear 4030, transmitting the power output from the drive motor 4032 to the connecting gear 4030, which in turn drives the guide vane 401 to rotate. It serves as the power transmission hub for the entire angle adjustment assembly 403. The drive gear 4031 is also a gear structure, with its dimensions and tooth profile matching those of the connecting gear 4030 to achieve precise meshing and transmission. The drive gear 4031 and the output shaft of the drive motor 4032 are connected via a coupling or a direct key.

[0057] The drive motor 4032 provides power to the entire angle adjustment assembly 403. The rotation of its output shaft drives the drive gear 4031, thereby adjusting the angle of the guide vanes 401. The drive motor 4032 can be connected to a power source via wires to obtain electrical energy; the output shaft and drive gear 4031 are connected via a coupling or key to transmit power.

[0058] The drive chamber 4033 provides a safe and stable installation space for the drive motor 4032, while also protecting the motor from external factors such as dust and moisture. The drive chamber 4033 is generally a closed cavity structure to ensure a tight fit of the motor; its shape is typically rectangular or square, adapting to the lower structure of the guide frame 400. The drive chamber 4033 can be connected to the guide frame 400 with bolts, facilitating installation and disassembly, and enabling convenient maintenance and repair of the drive motor 4032.

[0061] The adjustable air intake deflector 40 includes:

[0062] The airflow guide frame 400 is connected to the outside of the air intake mounting chamber 2;

[0063] The guide vanes 401 are arranged obliquely in sequence along the longitudinal direction within the guide frame 400, and the guide vanes 401 are rotatably connected to the guide frame 400 through the rotating shaft 402.

[0064] Angle adjustment component 403 is used to adjust the tilt angle of the guide vane 401.

[0065] The guide frame 400 serves as the basic support structure for the entire adjustable intake guide vane 40, supporting the guide vanes 401 and securely connected to the intake mounting chamber 2, guiding outside air into the intake mounting chamber 2. The guide frame 400 is a frame assembled from multiple frames, forming a regular space inside for installing the guide vanes 401.

The guide frame 400 can be firmly connected to the intake mounting chamber 2 via bolts or welding.

[0066] The guide vanes 401 precisely control the airflow and direction entering the air intake installation chamber 2 by changing their tilt angle.

The guide vanes 401 are typically thin-plate structures with a rotating shaft 402 at one end for rotatable connection to the guide frame 400. They are generally elongated strips, arranged longitudinally and obliquely within the guide frame 400, maintaining a certain spacing between the vanes to ensure airflow and facilitate angle adjustment. The guide vanes 401 are rotatably connected to the guide frame 400 via the rotating shaft 402, which is fixed integrally with the guide vanes 401.

[0067] Example 3:

[0068] This embodiment provides an American-style transformer with anti-condensation function, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0069] The angle adjustment component 403 includes:

[0070] A connecting gear 4030 is provided outside the flow guide frame 400, which is connected to the rotating shaft 402 and corresponds one-to-one with multiple rotating shafts 402. The connecting gears 4030 mesh with each other.

[0071] The drive gear 4031 meshes with the connecting gear 4030 located at the bottom. The guide frame 400 is also provided with a drive motor 4032 for driving the drive gear 4031 to rotate.

[0072] The drive chamber 4033 is located below the flow guide frame 400 and is used to house the drive motor 4032.

[0073] The connecting gear 4030 is used to transmit power, converting the rotation of the drive gear 4031 into the synchronous rotation of each guide vane 401, thereby achieving the purpose of synchronously adjusting the tilt angle of the guide vanes 401. The connecting gear 4030 can be a standard gear structure with evenly distributed teeth and a central shaft hole for tight connection with the rotating shaft 402 of the guide vanes 401. The connecting gear 4030 can also be tightly connected to the rotating shaft 402 via a key.

[0074] The drive gear 4031 meshes with the connecting gear 4030, transmitting the power output from the drive motor 4032 to the connecting gear 4030, which in turn drives the guide vane 401 to rotate. It serves as the power transmission hub for the entire angle adjustment assembly 403. The drive gear 4031 is also a gear structure, with its dimensions and tooth profile matching those of the connecting gear 4030 to achieve precise meshing and transmission. The drive gear 4031 and the output shaft of the drive motor 4032 are connected via a coupling or a direct key.

[0075] The drive motor 4032 provides power to the entire angle adjustment assembly 403.

The drive chamber 4033 can be connected to the guide frame 400 with bolts, facilitating installation and disassembly, and enabling convenient maintenance and repair of the drive motor 4032.

[0077] Example 4:

[0078] This embodiment provides an American-style transformer with anti-condensation function, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0079] The replaceable drying box 42 includes:

[0080] The housing 420 is located inside the intake fan 41;

[0081] A movable guide rail 421 is provided on the inner bottom surface of the air intake installation chamber 2, and a movable guide block 422 that cooperates with the guide rail is provided at the bottom of the box body 420.

[0082] Handle 423 is used to drive the box 420 to move on the moving guide rail 421.

[0083] The housing 420 is used to hold desiccant, which absorbs moisture from the air entering the air intake chamber 2, reducing air humidity and preventing condensation inside the transformer, thus ensuring the normal operation of electrical components. The housing 420 is generally designed as a cuboid, a shape that facilitates efficient layout within the air intake chamber 2 and maximizes the use of internal space for desiccant placement. The housing 420 is slidably connected to the air intake chamber 2 via a sliding guide rail 421 and a sliding guide block 422.

[0084] The movable guide rail 421 provides guidance and support for the movement of the housing 420, ensuring that the housing 420 can smoothly and easily enter and exit the air inlet installation chamber 2 when the desiccant is replaced, while also ensuring the stability of the housing 420 in the working state. The movable guide rail 421 is generally a long strip-shaped groove structure and can be integrally molded with the air inlet installation chamber 2.

[0085] The movable guide block 422 cooperates with the movable guide rail 421, allowing the box 420 to move freely on the guide rail. The guide block transfers the weight of the box 420 to the guide rail while limiting the direction of movement of the box 420, ensuring the stability and accuracy of the box 420 during movement. The movable guide block 422 is a block-shaped structure that matches the movable guide rail 421. Its shape is commonly T-shaped or dovetail-shaped, ensuring a tight fit with the guide rail and preventing the box 420 from shaking or derailing during movement. The movable guide block 422 can be connected to the bottom or top of the box 420 by screws or by integral molding.

[0086] Handle 423 allows operators to manually pull the box body 420 to replace the dryer box. Handle 423 provides a comfortable grip, allowing operators to easily pull or push the box body 420 out of the air inlet chamber 2. Handle 423 is typically a handle-like structure, with one end connected to the box body 420 and the other end designed for easy hand gripping, such as an arc or straight rod shape. Some handles 423 may also have an anti-slip design. Handle 423 and box body 420 can be connected by screws, snap-fit ​​connections, or integral molding.

[0087] Example 5:

[0088] This embodiment provides an American-style transformer with anti-condensation function, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0089] The heating component 43 includes:

[0090] The fixed frame 430 is located inside the air intake installation chamber 2 and inside the replaceable dryer box 42;

[0091] Heating wires 431 are arranged longitudinally within the fixed frame 430;

[0092] A connecting sleeve 432 is fitted onto both ends of each heating wire 431, and the connecting sleeve 432 is connected to the fixed frame 430.

[0093] The fixing frame 430 provides stable support and fixation for the heating wire 431, ensuring that the heating wire 431 maintains the correct position during operation and preventing displacement due to vibration or other factors that could affect the heating effect or cause safety issues. Simultaneously, it connects the heating assembly 43 to the air intake mounting chamber 2, making it a single integrated structure. The fixing frame 430 can be a frame structure composed of multiple frames, typically rectangular in shape. This shape facilitates reasonable layout within the air intake mounting chamber 2 and effectively supports the linear arrangement of the heating wire 431. The fixing frame 430 is fixed within the air intake mounting chamber 2 by welding or bolting.

[0094] When current flows through the heating wire 431, it generates resistance heat, converting electrical energy into heat energy. This raises the temperature of the air inside the air intake chamber 2, thereby increasing the internal temperature of the transformer and preventing condensation of moisture in the air due to excessively low temperatures, thus protecting the electrical components inside the transformer. The heating wire 431 can be made of a metal wire with high resistance, arranged in a spiral or straight shape closely within the fixed frame 430 to increase the heating area and improve heating efficiency. Both ends of the heating wire 431 are connected to the fixed frame 430 via connecting sleeves 432.

[0095] The connecting sleeve 432 serves two purposes: firstly, it enables the electrical connection between the heating wire 431 and the fixed frame 430, ensuring that current can smoothly pass through the heating wire 431 to generate heat; secondly, it securely fixes the heating wire 431 to the fixed frame 430, preventing it from loosening or shifting during operation. The connecting sleeve 432 is generally a hollow sleeve structure with an internal diameter matching the diameter of the heating wire 431. Its shape is typically cylindrical, open at both ends, with one end fitted onto the heating wire 431 and the other end connected to the fixed frame 430. The connecting sleeve 432 and the heating wire 431 are tightly fitted, such as with an interference fit or by welding, to ensure the reliability of the electrical connection; and it is fastened to the fixed frame 430 with screws or welded to ensure the strength of the connection.

[0096] Example 6:

[0097] This embodiment provides an American-style transformer with anti-condensation function, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0098] The diffusion component 31 includes:

[0099] The exhaust section 310 is located on the outside of the exhaust port 10, and the exhaust section 310 has a trumpet-shaped structure with the diameter gradually increasing from the inside to the outside.

[0100] The diffuser 311 is connected to the outlet of the exhaust section 310, and the diffuser 311 has a funnel-shaped structure similar to that of the exhaust section 310.

[0101] The exhaust section 310 guides the gas discharged from the exhaust port 10, initially expanding the gas discharge diameter and accelerating the gas flow rate, preparing for subsequent gas diffusion. It can initially disperse the concentrated discharged gas, preventing excessively high local gas flow rates or pressures. The exhaust section 310 is typically a cavity structure with a certain thickness, shaped like a trumpet with its diameter gradually increasing from the inside to the outside. This shape conforms to the principles of gas dynamics, facilitating gradual diffusion of the gas during discharge, reducing gas velocity and pressure, and allowing it to enter the subsequent diffuser section 311 more evenly. The exhaust section 310 and the exhaust port 10 can be connected by welding or a flange.

[0102] The diffuser 311 further expands the gas discharge range, ensuring the discharged gas is evenly dispersed into the surrounding environment. This prevents the gas from accumulating in localized areas, improves ambient air quality, and reduces the impact of concentrated gas emissions on surrounding equipment and the environment. The diffuser 311 is also a cavity structure, similar in shape to the exhaust 310, exhibiting a trumpet-like shape with its diameter gradually increasing from the inside to the outside. The outlets of the diffuser 311 and the exhaust 310 can be connected by welding or bolts.

[0103] Example 7:

[0104] This embodiment provides an American-style transformer with anti-condensation function, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0105] The air intake installation chamber 2 is equipped with a filter plate 5, which is located between the adjustable air intake guide plate 40 and the air intake fan 41.

[0106] The filter plate 5 is used to filter the air entering the air intake installation chamber 2, intercepting dust, impurities, and other particles in the air to prevent them from entering the transformer and causing wear, short circuits, or other damage to internal electrical components, the ventilation and drying mechanism 4, and other parts, thus ensuring the normal operation and service life of the transformer. The filter plate 5 generally consists of a filter layer and a support frame. The filter layer is the core component for achieving the filtration function and is usually made of a material with a certain porosity; the support frame is used to fix the filter layer and ensure its structural stability. The filter plate 5 is generally flat, and its dimensions are adapted to the cross-section of the air intake channel in the air intake installation chamber 2 to ensure complete coverage of the air intake channel and effective air filtration. The filter plate 5 can be fixed in the air intake installation chamber 2 by means of slots, bolts, or welding.

[0107] Example 8:

[0108] This embodiment provides an American-style transformer with anti-condensation function, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0109] The filter plate 5 is equipped with a temperature sensor 6 for real-time monitoring of the internal temperature of the body 1 and a humidity sensor 7 for measuring air humidity.

[0110] Temperature sensor 6 is used to monitor the internal temperature of the transformer body 1 in real time, providing accurate temperature data to the system. This allows the control system to make corresponding decisions based on temperature changes, such as adjusting the working status of the heating component 43 and controlling the operating intensity of the ventilation system. This effectively prevents condensation inside the transformer due to abnormal temperature, ensuring stable operation of the transformer. Temperature sensor 6 can be connected to the control system via wires to transmit the collected temperature signals.

[0111] Humidity sensor 7 is used to measure the humidity of the air inside the transformer housing 1 in real time, providing humidity data to the system so that the control system can precisely adjust the ventilation and drying mechanism 4 according to the humidity level. For example, when the humidity exceeds the standard, the intake fan 41 and exhaust fan 30 are activated to enhance ventilation, or the replaceable drying box 42 is replaced, effectively preventing condensation caused by excessive humidity and ensuring the safe operation of the electrical components inside the transformer. Humidity sensor 7 can be connected to the control system via a wire to transmit the humidity signal to the control system.
