Abstract
Description
Technical Field
[0001] This utility model belongs to the field of transformer technology, and in particular to a transformer with overheat protection. Background Technology
[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil, and the iron core. Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization.
[0003] Most existing transformers are installed outdoors and are exposed to the elements. Therefore, during daily use, the high temperatures and heavy loads on their electronic components can cause the transformers to overheat, leading to damage and safety accidents. However, existing transformers lack overheat protection devices, so they cannot cut off the power supply in time when high temperatures occur, allowing the high temperatures to persist until the transformer is damaged and a safety accident occurs. Therefore, there is an urgent need for a transformer with overheat protection to solve this problem. Utility Model Content
[0004] The purpose of this invention is to provide a transformer with overheat protection to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a transformer with overheat protection, comprising a base plate for transformer mounting and a housing for transformer overheat protection mounting, wherein a controller and a temperature sensor are mounted on the top surface of the transformer, the transformer is fixedly mounted on the top surface of the base plate, the housing is fixedly connected to the top surface of the transformer, two input lines are fixedly connected to the top surface of the housing and extend into the interior of the housing, two fixing posts are fixedly connected to the top surface inside the housing, fixing plates are fixedly connected to the bottom of the fixing posts, springs are connected to the bottom of the fixing plates, pressure plates are fixedly connected to the bottom of the springs, and electromagnets for transformer overheat protection are mounted on the bottom of the fixing plates and the top surface of the pressure plates;
[0006] Two arc-shaped plates are fixedly connected to the bottom of the pressure plate, and two connecting columns are fixedly connected to the lower interior of the housing. Output lines are fixedly connected to the side walls of the connecting columns. The arc-shaped plates are located above the connecting columns, and the ends of the input lines are electrically connected to the arc-shaped plates.
[0007] Preferably, the side walls of the two arc-shaped plates are fixedly connected to connecting plates, and the lower interior of the box is fixedly connected to two vertical rods.
[0008] Preferably, the two connecting plates are provided with longitudinal sliding holes, and the two vertical rods slide through the two sliding holes.
[0009] Preferably, the top surface of the pressure plate is fixedly connected with multiple limiting rods, and the fixed plate has multiple through holes.
[0010] Preferably, the multiple limiting rods fixedly connected to the top surface of the pressure plate slide through the multiple through holes opened on the fixed plate.
[0011] Preferably, the two arc-shaped plates are matched with the connecting column.
[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows:
[0013] This transformer with overheat protection works by using a fixed plate, electromagnets, springs, and pressure plates. When the temperature sensor detects that the transformer is overheating, the transformer transmits a signal to the controller. The controller then energizes the electromagnets, causing them to become magnetic and attract each other. This causes the pressure plates to lift the two arc-shaped plates at their lower ends, moving them away from the connecting posts and thus disconnecting the power to the transformer. This effectively cuts off the power to the transformer and prevents damage to its internal components.
[0014] This transformer with overheat protection benefits from the spring design. When the temperature sensor detects a drop in the transformer temperature, the controller will de-energize the two electromagnets, causing them to lose their magnetism. At this point, the spring will push the pressure plate and the two arc-shaped plates to fit tightly against the connecting column, thus making the connection between the arc-shaped plates and the connecting column more stable.
[0015] Compared with existing technologies, this transformer with overheat protection can automatically cut off the power to the transformer when the transformer reaches a high temperature, thereby protecting the internal components of the transformer and preventing safety accidents.

[0023] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.
[0024] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.
[0025] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.
[0026] like Figures 1 to 4 The main structure of a transformer with overheat protection is shown as a base plate 1 for transformer installation and a housing 4 for transformer overheat protection installation. A controller 16 and a temperature sensor 12 are installed on the top surface of the transformer 2. The temperature sensor 12, the controller 16 and two electromagnets 8 are electrically connected.
[0027] A transformer 2 is fixedly installed on the top surface of the base plate 1. The housing 4 is fixedly connected to the top surface of the transformer 2. Two input lines 5 are fixedly connected to the top surface of the housing 4 and extend into the interior of the housing 4. Two fixed posts 6 are fixedly connected to the top surface inside the housing 4. A fixed plate 7 is fixedly connected to the bottom of the fixed post 6. A spring 14 is connected to the bottom of the fixed plate 7. A pressure plate 9 is fixedly connected to the bottom of the spring 14. When the temperature sensor 12 detects that the temperature of the transformer 2 has dropped to a safe value, the controller 16 will de-energize the two electromagnets 8. At this time, the spring 14 will push the pressure plate 9 and the arc plate 10 to move downward. Then, the spring 14 will press the two arc plates 10 against the side wall of the connecting post 11 again, thereby re-energizing the transformer 2.
[0028] Electromagnets 8 for transformer overheat protection are installed on the bottom of the fixing plate 7 and the top surface of the pressure plate 9. When the temperature of the transformer 2 exceeds the predetermined temperature, the temperature sensor 12 will output an electrical signal to the controller 16 because the temperature sensor 12 is electrically connected to the controller 16. At this time, the controller 16 will energize the two electromagnets 8, which will generate magnetism and cause the pressure plate 9 to move upward. The pressure plate 9 will then lift the two arc plates 10, thereby moving the arc plates 10 away from the connecting column 11, thus disconnecting the power to the transformer 2 and preventing the transformer 2 from continuing to overheat.
[0029] Two arc-shaped plates 10 are fixedly connected to the bottom of the pressure plate 9. The arc-shaped plates 10 are electrically connected to the input line 5 through a flexible connecting wire.
[0030] Two connecting posts 11 are fixedly connected to the lower part of the inner side of the housing 4. Output lines are fixedly connected to the side walls of the connecting posts 11. The arc plate 10 is located above the connecting posts 11, and the end of the input line 5 is electrically connected to the arc plate 10.
[0031] Both arc-shaped plates 10 are fixedly connected to the side walls of the two arc-shaped plates 10. Two vertical rods 3 are fixedly connected to the lower end of the inner side of the box body 4. The two connecting plates 13 are longitudinally provided with sliding holes. The two vertical rods 3 slide through the two sliding holes. Thanks to the setting of the vertical rods 3, the sliding direction of the two arc-shaped plates 10 can be effectively limited, and the stability of the arc-shaped plates 10 during sliding can be further improved.
[0032] Multiple limiting rods 15 are fixedly connected to the top surface of the pressure plate 9. Multiple through holes are opened on the fixing plate 7. The multiple limiting rods 15 fixedly connected to the top surface of the pressure plate 9 slide through the multiple through holes opened on the fixing plate 7. Thanks to the setting of multiple limiting rods 15, the sliding direction of the pressure plate 9 and the two arc plates 10 can be effectively limited.
[0033] The two arc-shaped plates 10 are matched with the connecting post 11, so that the arc-shaped plates 10 fit more closely when connected to the connecting post 11, thereby making the electrical connection more stable.
[0034] Working principle
[0035] When the transformer 2 experiences high temperature during use, the temperature sensor 12 detects the temperature of the transformer 2. When the temperature of the transformer 2 exceeds the predetermined temperature, since the temperature sensor 12 is electrically connected to the controller 16, the temperature sensor 12 outputs an electrical signal to the controller 16. At this time, the controller 16 energizes the two electromagnets 8, which generate magnetism and cause the pressure plate 9 to move upward. The pressure plate 9 lifts the two arc-shaped plates 10, moving them away from the connecting post 11, thereby disconnecting the power to the transformer 2 and preventing the transformer 2 from continuing to overheat and damaging its internal components. When the temperature sensor 12 detects that the temperature of the transformer 2 has dropped to a safe value, the controller 16 disconnects the power to the two electromagnets 8. At this time, the spring 14 pushes the pressure plate 9 and the arc-shaped plates 10 downward, and the spring 14 brings the two arc-shaped plates 10 back onto the side wall of the connecting post 11, thereby re-energizing the transformer 2.
