Description

An energy-saving transformer protection system Technical Field

[0001] This invention relates to the field of power equipment technology, specifically to an energy-saving transformer protection system. Background Technology

[0002] A transformer is a static electrical device that uses the principle of electromagnetic induction to transform AC voltage, current, or impedance. Its core function is to convert input AC power into output power of different voltage levels by changing the winding turns ratio, while maintaining a basically constant power. An energy-saving transformer, on the other hand, is a power transformer that significantly reduces no-load loss and load loss through optimized design, material upgrades, and process improvements, thereby improving energy utilization efficiency, reducing reactive power consumption of the power grid, and meeting national or international energy efficiency standards. Its core objective is to achieve lower energy consumption, higher environmental protection, and economic benefits throughout its entire life cycle.

[0003] Currently, energy-saving transformers typically dissipate heat by having heat sink fins contact the external environment. To ensure the heat dissipation effect of the fins, anti-rust paint is usually applied to the surface of the fins to prevent corrosion. However, since the heat sink fins are in direct contact with the external environment, they are easily affected by it. For example, dust accumulation reduces the contact area between the fins and the environment, affecting the heat dissipation effect. Long-term exposure to sunlight or water can cause cracks in the paint at the edges of the fins, leading to peeling and affecting the anti-rust effect. This, in turn, affects the heat dissipation effect and poses a certain threat to the normal operation of the transformer. Summary of the Invention

[0004] The purpose of this invention is to provide an energy-saving transformer protection system to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: The present invention is an energy-saving transformer protection system, including a transformer, on which heat dissipation fins are provided for heat dissipation of the transformer, and a protective frame is fitted on the heat dissipation fins. The inner sidewall of the protective frame is concave to wrap the corners of the heat dissipation fins. The protective frame is made of thermally conductive material and is in close contact with the heat dissipation fins. A sunshade is provided on the protective frame to shield the heat dissipation fins. The top of the sunshade is sloped to remove dust from the top of the sunshade.

[0006] Furthermore, a fixed base is installed on the sunshade, an adjusting screw is rotatably installed on the fixed base, and an adjusting cylinder is slidably installed on the fixed base. The adjusting cylinder is fitted onto the adjusting screw. A sealing plate is slidably installed on the sunshade and connected to the adjusting cylinder. A rubber strip is provided on one side of the sealing plate. After the sunshade is installed, rotating the adjusting screw moves the adjusting cylinder, causing the sealing plate to push the rubber strip into close contact with the transformer, reducing the flow of water along the outer wall of the transformer to the heat dissipation fins.

[0007] Furthermore, a reinforcing block is installed on the protective frame, and a rotating bolt is provided on the reinforcing block. A reinforcing abutment is provided on the other side of the reinforcing block. The reinforcing abutment is connected to one end of the rotating bolt, and the rotating bolt is threadedly connected to the reinforcing block. By rotating the rotating bolt, the reinforcing abutment is pushed to move, so that the reinforcing abutment contacts the outer wall of the heat dissipation fins. Through the interaction of forces, the protective frame and the heat dissipation fins are firmly connected.

[0008] Furthermore, a cooling fan is installed on the sunshade, and a wind deflector is installed on the protective frame. The wind deflector guides the airflow blown by the cooling fan to the space between the two corresponding heat dissipation fins, thereby improving the heat dissipation effect of the heat dissipation fins.

[0009] Furthermore, the number of wind deflectors is set to multiple, and the height of the multiple wind deflectors increases with the distance from the cooling fan, in order to evenly disperse the airflow blown out by the cooling fan. The wind deflectors are made of rubber material with high hardness.

[0010] Furthermore, a connecting frame is installed on the sun visor, and a rotating shaft is rotatably mounted on the connecting frame. A power fan blade is sleeved on the rotating shaft. An adjusting frame is set on the connecting frame, and some components of the adjusting frame are connected to the rotating shaft. An air guide tube is set on the adjusting frame, and a piston is set on the air guide tube. The piston is connected to some components of the adjusting frame. The rotating shaft is driven to rotate by the power fan blade, and the piston is driven to reciprocate within the air guide tube by the adjusting frame. An air guide strip is installed on the protective frame. The air guide strip has a hollow structure. An air guide pipe is installed on the air guide tube and is connected to the air guide strip. An exhaust hole is set on the air guide strip, and an air inlet pipe is set on the air guide tube. Both the air inlet pipe and the air guide pipe are equipped with one-way valves.

[0011] Furthermore, the air guide is located in the middle of the heat dissipation fins, and the side of the air guide near the heat dissipation fins is provided with two inclined surfaces with an inclination between 45 and 60 degrees. The exhaust port is located on the inclined surface.

[0012] Furthermore, a T-shaped groove is provided on the air guide strip, and a vibrating block is installed in the T-shaped groove. A connecting hole is provided on the air guide strip, and one end of the connecting hole is connected to the bottom inner wall of the T-shaped groove. After the airflow flows into the air guide strip, it acts on the vibrating block through the connecting hole, pushing the vibrating block to rise. After the airflow supply stops, the vibrating block falls and collides with the air guide strip, generating vibration. The vibration force causes the dust on the heat dissipation fins to fall off.

[0013] Furthermore, the adjusting frame consists of a limiting frame, a moving rod, a first connecting plate, and a second connecting plate. The limiting frame is installed on the connecting frame and connected to the air guide cylinder. The moving rod is slidably installed inside the limiting frame, with one end extending into the air guide cylinder and connected to the piston. The first connecting plate is installed on the rotating shaft, and the second connecting plate is rotatably installed on the first connecting plate. The second connecting plate is rotatably connected to the moving rod. An opening is provided on one side of the air guide cylinder, through which the moving rod passes and is movably connected. The opening avoids obstructing the movement of the piston.

[0014] The present invention has the following beneficial effects: (1) By setting a protective frame and fitting the protective frame onto the heat dissipation fins, the corners of the heat dissipation fins are protected, thereby reducing the probability of the anti-rust paint on the surface of the heat dissipation fins peeling off, ensuring the heat dissipation effect of the heat dissipation fins, and also reducing the maintenance cost of the transformer. By setting a sunshade above the heat dissipation fins, water flow can be effectively reduced from adhering to the heat dissipation fins, and direct exposure of the heat dissipation fins to sunlight can also be reduced, thus reducing the peeling of the paint on the surface of the heat dissipation fins, improving the protection effect of the heat dissipation fins, and ensuring the stable heat dissipation of the transformer.

[0015] (2) By setting up a baffle plate, the airflow blown by the cooling fan is guided to the space between the two corresponding heat dissipation fins, thereby improving the heat dissipation effect of the heat dissipation fins on the transformer. At the same time, by guiding the airflow, the airflow acts on the surface of the heat dissipation fins, and the airflow removes the dust on the surface of the heat dissipation fins, preventing dust or water from adhering and improving the protection effect of the heat dissipation fins. In addition, by setting an arc-shaped top plate on the protective frame, dust can also be blocked to a certain extent and water can be guided, so that the heat dissipation fins are less in contact with dust and water, further improving the protection effect of the heat dissipation fins.

[0016] (3) By setting up air guide strips and exhaust holes, as well as by setting up power fan blades and adjustment frame, the power fan blades are rotated under the action of external wind force. The adjustment frame applies the rotational force to the piston, causing the piston to move back and forth in the air guide tube, stirring the airflow. The airflow is then applied to the air guide hook strip through the air guide pipe and discharged through the exhaust hole, which can form an airflow impact. This airflow impact can better remove impurities from the surface of the heat dissipation fins and improve the protection effect of the heat dissipation fins.

[0017] (4) By setting a vibration block and a T-shaped groove on the air guide strip, the present invention can cause part of the impact force of the airflow to be applied to the vibration block through the connecting hole when the airflow enters the air guide strip, so that the vibration block rises and falls and forms a collision vibration with the air guide strip. The vibration force is applied to the heat dissipation fins, which can shake off the dust on the heat dissipation fins and further improve the protection effect of the heat dissipation fins.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

By rotating the rotating bolt 12, the reinforcing abutment 13 is pushed to move, so that the reinforcing abutment 13 contacts the outer wall of the heat dissipation fin 2. Through the interaction of forces, the protective frame 3 and the heat dissipation fin 2 are firmly connected.

[0025] A cooling fan 5 is installed on the sunshade 4, and a wind deflector 10 is installed on the protective frame 3.

An air guide strip 14 is installed on the protective frame 3. The air guide strip 14 has a hollow structure. An air duct 21 is installed on the air duct 19, which is connected to the air guide strip 14. The air guide strip 14 has an exhaust port. An air inlet pipe is installed on the air duct 19. Both the air inlet pipe and the air duct 21 are equipped with one-way valves. The one-way valve on the air inlet pipe is used to input airflow into the air duct 19, and the one-way valve on the air guide strip 21 is used to discharge airflow from the air duct 19. The air duct 21 is made of flexible hose. A protective plate 22 is installed on the sunshade 4. The power fan blade 17 is located below the protective plate 22 to protect the power fan blade 17.

The exhaust port is located on the inclined surface. A T-shaped groove is formed on the air guide 14, and a vibrating block 15 is placed inside the T-shaped groove. A connecting hole is formed on the air guide 14, and one end of the connecting hole is connected to the bottom inner wall of the T-shaped groove. After the airflow flows into the air guide 14, it acts on the vibrating block 15 through the connecting hole, pushing the vibrating block 15 to rise. After the airflow is stopped, the vibrating block 15 falls and collides with the air guide 14, generating vibration. The vibration force dissipates heat. Dust falls off the fins 2.

[0027] Before use, install the protective frame 3 onto the heat dissipation fins 2 to protect the corners of the heat dissipation fins 2. Then, reinforce the connection between the protective frame 3 and the heat dissipation fins 2 by rotating the bolts 12 and the reinforcing plate 13. Next, install the sunshade 4 onto the protective frame 3 using the connecting rod, threaded rod, and threaded cylinder to shield the entire heat dissipation fins 2. Then, rotate the adjusting screw 8 to move the adjusting screw cylinder 9, which in turn moves the sealing plate 6, reinforcing the tightness of the connection between the sunshade 4 and the surface of the transformer 1. During use, start the cooling fan 5 to blow airflow. The airflow is guided to the two corresponding heat dissipation fins 2 by the baffle plate 10, which increases the heat dissipation effect of the heat dissipation fins 2 and blows away the dust attached to the surface of the heat dissipation fins 2, making the surface of the heat dissipation fins 2 clean. This process ensures greater cleanliness, thus guaranteeing the contact area between the heat dissipation fins 2 and the external environment, and ensuring the heat dissipation effect of the heat dissipation fins 2. At the same time, when there is wind blowing from the outside, it will drive the power fan blades 17 to rotate, thereby driving the rotating shaft to rotate. Then, through the adjusting bracket, the piston 20 will reciprocate within the air guide cylinder 19, thereby agitating the airflow. The airflow flows through the air guide pipe 21 into the air guide strip 14, and then acts on the surface of the heat dissipation fins 2 through the exhaust hole, forming an airflow impact on the surface of the heat dissipation fins 2, which better removes the dust or water adhering to the surface of the heat dissipation fins 2. At the same time, the airflow acts on the vibrating block 15 through the connecting hole, causing the vibrating block 15 to rise and fall, forming a vibration between it and the air guide strip 14. This vibration shakes off the dust on the surface of the heat dissipation fins 2, improving the cleaning effect on the surface of the heat dissipation fins 2.
