Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and more specifically, to an intelligent transformer with an intelligent protection function. Background Art

[0002] The most basic function of a transformer is to change voltage. When high voltage needs to be reduced to a level suitable for equipment, a step-down transformer is used. This voltage conversion function enables electricity to be transmitted and distributed efficiently and safely. Transformers can also be used to adjust the voltage level in the power grid to meet the voltage requirements of different regions and equipment, ensuring the stability and reliability of power supply.

[0003] After searching the existing published technical documents, the Chinese patent announcement number CN111508696A discloses a dry-type transformer, which is connected to a second air intake valve through an air return pipe, so that the temperature and humidity sensor monitors the air humidity at the fan port in real time. When the humidity is high, the first air intake valve is closed, and the air is dried through the drying plate. After drying, the air enters the fan through the second air intake valve to improve the dryness of the air. At the same time, a rotating part is set at the air duct to rotate the drying plate to facilitate drying the drying plate. The transformer also has the following defects during use.

[0004] When the transformer terminals have abnormal temperatures during the transformer transformation process, the terminals need to be powered off to achieve self-protection of the transformer. However, an arc will be generated at the terminals during the power-off process, and the arc on the terminals will continue to discharge and generate high temperature, which will cause the insulating material inside the transformer to age, deform, or even burn rapidly. Therefore, it is difficult to achieve multi-point synchronous separation and power off, and it is difficult to quickly disperse and isolate the arc energy on the terminals, resulting in poor transformer protection effect. Therefore, an intelligent transformer with intelligent protection function is needed. Summary of the invention

[0015] Technical effects and advantages of the present invention:

[0016] 1. The present invention uses a first-level horizontal synchronous separation and blocking mechanism. When the abnormal temperature sensed by the temperature sensor is higher than the temperature set by the wireless controller, the wireless controller immediately starts the electric cylinder, the hinged ring carries the connecting shaft forward, the connecting shaft drives the rear end of the sleeve rod to move forward, and the sleeve strip carries multiple detachment terminals to move rightward.

[0017] 2. The present invention adopts a vertical synchronous separation and blocking mechanism.

[0018] 3. The present invention utilizes a two-level horizontal synchronous separation and blocking mechanism. When the articulated ring moves forward, it will drive the articulated shaft to move forward at the same time. The articulated shaft carries the rear end of the linkage sleeve rod to move forward. The linkage sleeve rod carries the articulated rod to move left. The separation plate drives multiple horizontal separation terminals to move left. The horizontal separation terminals, docking terminals, and collecting terminals are separated and disconnected by moving left. The isolation baffle is located between the docking terminals and the collecting terminals to insulate and block the arc. The arc between the docking terminals and the collecting terminals can be quickly blocked and extinguished, and multi-point synchronous separation and power-off can be achieved. The arc energy is quickly dispersed and isolated, and the arc extinguishing speed is faster.

[0019] The above-mentioned multiple effects influence each other. First, the detached terminal is quickly separated and disconnected from the contact terminal and the power-on terminal. The insulating block is located between the contact terminal and the power-on terminal to perform insulation blocking. At the same time, the vertically separated terminal is synchronously separated from the power-on terminal and the docking terminal by sliding down. The insulating partition is located between the docking terminal and the power-on terminal to perform insulation blocking. At the same time, the horizontally separated terminal is separated and disconnected from the docking terminal and the collecting terminal by moving left. The isolating baffle is located between the docking terminal and the collecting terminal to perform insulation blocking of the arc. In summary, the first and second level horizontal synchronous separation and arc blocking can be achieved, as well as the vertical synchronous separation and arc blocking can be achieved at the same time. The multi-point synchronous separation and power-off can quickly disperse and isolate the arc energy, and the arc can be extinguished faster, thereby achieving intelligent protection effect and greatly improving the transformer protection effect.

[0038] The working principle of the intelligent transformer with intelligent protection function in this technical solution is as follows:

[0039] Step 1: When using the transformer, multiple high-voltage connectors 14 are docked on the high-voltage wire harness, so that the high voltage is directed to the contact terminal 2 through the high-voltage connector 14, and then to the disengagement terminal 3 through the contact terminal 2. The disengagement terminal 3 is directed to the vertical separation terminal 28 through the power-on terminal 30, and the vertical separation terminal 28 is directed to the docking terminal 37. The high-voltage current is directed along the docking terminal 37 to the horizontal separation terminal 36 and then to the collection terminal 38, which is connected to the winding 19 by the harness. The magnetic coupling effect is enhanced inside the winding 19 through the iron core 20, and is transmitted to the harness 18 through the winding 19, and then to the step-down terminal 17 by the harness 18. The step-down terminal 17 is transformed and transmitted through the step-down connector 16 to realize the transformer operation. At the same time, the protective door 15 closes the housing 1 to prevent non-professionals from getting an electric shock, and to realize the protective operation.

[0040] Step 2, during the first-level horizontal synchronous separation and blocking, when the temperature sensor 39 realizes temperature sensing of the collecting terminal 38, the reinforcement frame 27 can provide support for the temperature sensor 39. When the abnormal temperature sensed by the temperature sensor 39 is higher than the temperature set by the wireless controller 43, the backup battery 44 can provide backup power to the wireless controller 43 to ensure that the wireless controller 43 can continue to be used after power failure.

[0041] The wireless controller 43 immediately starts the electric cylinder 12, which pushes the connection block 11 forward, and the connection block 11 drives the connection rod 10 forward, and the connection rod 10 drives the hinge ring 9 forward, and the hinge ring 9 carries the connection shaft 8 forward, and the connection shaft 8 drives the rear end of the sleeve rod 7 forward, and the sleeve rod 7 carries the support shaft 6 to move rightward, and the support shaft 6 drives the sleeve strip 5 to move rightward, and the sleeve strip 5 slides rightward along the outer wall of the sliding column 41. At the same time, the sleeve strip 5 moves rightward along the inner wall of the sliding frame 42, and the sleeve strip 5 carries multiple detachment terminals 3 to move rightward, and the detachment terminals 3 are quickly separated and disconnected from the contact terminals 2 and the power-on terminals 30. At the same time, the detachment terminals 3 drive the insulation block 13 to move rightward, and the insulation block 13 is located between the contact terminals 2 and the power-on terminals 30 for insulation blocking, so that the arc between the contact terminals 2 and the power-on terminals 30 can be quickly blocked and extinguished.

[0042] Step 3: When the vertical synchronous separation is blocked, when the hinged ring 9 moves forward, the hinged support shaft 21 will be driven forward, and the hinged support shaft 21 will carry the bottom end of the sleeve pull rod 22 forward, and the sleeve pull rod 22 will carry the hinged pull rod 23 downward, and the hinged pull rod 23 will drive the groove plate 24 downward, and the groove plate 24 will carry the sleeve slider 25 to slide down along the outer wall of the slide rod 26, and the reinforcement frame 27 will support the slide rod 26 to increase the stability of the slide rod 26. The groove plate 24 will also drive the vertical separation terminal 28 to move downward, and the vertical separation terminal 28 will move downward and separate from the power-on terminal 30, and the reinforcement frame 27 will support the insulating support plate 46, the insulating support plate 46 will support the insulating bracket 45, and the insulating bracket 45 will support the docking terminal 37. Keep the docking terminal 37 immovable, and the insulating support plate 46 can provide support force for the power-on terminal 30, keeping the power-on terminal 30 immovable. At the same time, the vertical separation terminal 28 and the docking terminal 37 slide down and separate, and the power is quickly separated and cut off. The vertical separation terminal 28 can drive the insulating partition 29 to move downward. The insulating partition 29 is located between the docking terminal 37 and the power terminal 30 to perform insulation blocking. The arc between the docking terminal 37 and the power terminal 30 can be quickly blocked and extinguished.

[0043] Step 4: During the second-level horizontal synchronous separation and blocking, when the hinge ring 9 moves forward, the hinge shaft 31 will be driven to move forward at the same time, and the hinge shaft 31 carries the rear end of the linkage sleeve rod 32 to move forward, and the linkage sleeve rod 32 carries the hinge rod 33 to move left, and the hinge rod 33 drives the linkage slot plate 34 to move left. The linkage slot plate 34 moves left along the outer wall of the sliding column 41, and the linkage slot plate 34 moves left along the inner wall of the sliding frame 42. The linkage slot plate 34 drives the separation plate 35 to move left, and the separation plate 35 drives multiple horizontal separation terminals 36 to move left, and the horizontal separation terminals 36 and the docking terminals 37 and the collection terminals 38 are separated and disconnected by left movement. At the same time, the horizontal separation terminals 36 can drive the isolation baffle 40 to move left, and the isolation baffle 40 is located between the docking terminals 37 and the collection terminals 38 to insulate and block the arc, and the arc between the docking terminals 37 and the collection terminals 38 can be quickly blocked and extinguished.
