A liquid storage chamber is connected to the inner wall surface of the housing, and a delivery pipe is connected to the lower end of the liquid storage chamber. A detection component is connected to the end of the delivery pipe furthest from the liquid storage chamber. The detection component is installed next to the transformer windings.

Description

Technical Field

[0001] This invention relates to the field of transformer technology, and more specifically, to an amorphous alloy dry-type distribution transformer. Background Technology

[0002] Amorphous alloy dry-type distribution transformers are widely used in various scenarios such as industrial production, residential power distribution, and commercial buildings due to their advantages of low loss, high efficiency, no oil pollution, and excellent insulation performance. Their operational stability is directly related to the safe and reliable power supply of the power system. As the core component of the transformer, the windings continuously generate heat during long-term operation. If the heat cannot be dissipated in time, it will cause the winding temperature to rise abnormally, which will not only accelerate the aging of insulation materials and reduce the service life of the transformer, but also cause safety accidents such as winding insulation breakdown and fire in severe cases. Therefore, accurate monitoring and effective protection of the winding temperature of amorphous alloy dry-type distribution transformers are the key to ensuring their long-term stable operation.

[0003] Existing overheat protection for amorphous alloy dry-type distribution transformers mostly employs temperature controllers in conjunction with resistance temperature detectors (RTDs), infrared sensors, or fiber optic sensors. Among these, RTD and infrared temperature protection systems are the most widely used. However, these protection methods generally suffer from slow response speeds and low triggering accuracy, making it difficult to quickly respond to sudden changes in winding temperature. This often results in delayed activation of the cooling mechanism, failing to promptly curb the temperature rise and hindering the achievement of precise multi-stage overheat protection. Furthermore, the thermal triggering media used in existing technologies to trigger cooling or protection mechanisms are either easily decomposable and corrosive chemical agents that generate harmful gases during use, corroding internal transformer components and posing safety hazards, or ordinary liquid media with unstable vaporization temperatures that cannot accurately match the safe temperature threshold of the transformer windings, leading to significant deviations in trigger timing and affecting protection effectiveness. In addition, some thermal triggering media cannot be recycled, requiring frequent replenishment over long-term use, increasing maintenance costs and operational complexity, and making the protection mechanism prone to failure due to media depletion. Summary of the Invention

The circular cavity is made of a heat-conducting material, and an infrared sensor is installed in the inner cavity of the first circular frame.

[0008] Preferably, a circular limiting block is connected to the upper surface of the lifting rod, an annular sealing block is connected to the lower surface of the circular limiting block, and an L-shaped connecting rod is connected to the top of the lifting rod. A second connecting block is connected to the end surface of the L-shaped connecting rod facing the fixing component. Fixing grooves are provided on both ends of the second connecting block, and the top of the second connecting block has a triangular structure. The initial position of the second connecting block is located below the fixing component.

[0009] Preferably, the upper surface of the first circular frame is provided with a plurality of second air leakage holes, the outer side of the second air leakage holes is connected to an annular sealing frame, and the top surface of the first circular frame is provided with an annular sealing groove.

[0010] Preferably, the first vent hole is conical, with the radius of the first vent hole gradually decreasing from the bottom to the top. The inner cavity of the circular cavity is filled with propylene glycol. The annular sealing groove fits into the annular sealing block, the fixing groove fits into the fixing block, and the second connecting block fits into the rectangular groove. When the fixing block and the fixing groove overlap, the wire, the two fixing blocks, and the second connecting block will form a circuit, thereby activating the cooling fan for cooling operation.

[0011] Preferably, the condensation assembly includes a spiral condenser tube, the top of which has a feed inlet, and both sides of the spiral condenser tube away from the feed inlet are connected to sealing components.

[0014] Compared with the prior art, the advantages of this invention are: 1. In this invention, the detection component is installed next to the transformer winding. The heat generated by the winding can be quickly transferred to the circular cavity through heat conduction. When the winding temperature exceeds the threshold, the vaporization rate of propylene glycol increases sharply, and the vapor pressure rises rapidly, pushing the first circular sliding block to rise.

After the condensate accumulates to a certain weight, it can push the semi-arc sealing block of the sealing component to open, and flow back into the circular cavity for reuse, realizing a closed-loop circulation of the heat triggering medium. There is no need to frequently replenish the medium, which greatly reduces maintenance costs and operational complexity. At the same time, propylene glycol is used as the heat triggering medium because it is non-corrosive, not easily decomposed, and will not produce harmful gases during use, thus avoiding corrosion of the internal components of the transformer.

[0019] Example: Please refer to Figure 1 , Figure 2 and Figure 3 An amorphous alloy dry-type distribution transformer includes a housing 1, a sliding door 2 connected to the front end of the housing 1, a liquid storage chamber 3 connected to the inner wall surface of the housing 1, a liquid delivery pipe 4 connected to the lower end of the liquid storage chamber 3, a detection component 7 connected to the end of the liquid delivery pipe 4 away from the liquid storage chamber 3, a cooling component 6 connected to one end of the detection component 7, a transformer 5 connected to the outside of the cooling component 6, and the detection component 7 installed next to the transformer windings. A temperature sensor is installed in the inner cavity of the transformer 5. The temperature sensor installed in the inner cavity of the transformer 5 monitors the winding temperature in real time. If the winding temperature is not effectively controlled after the cooling component 6 is activated and continues to rise to 140°C, the temperature sensor immediately sends a control signal to activate the circuit breaker protection mechanism, control the circuit breaker to operate, and automatically cut off the power supply circuits on the high and low voltage sides of the transformer 5, so that the transformer 5 stops operating, realizing secondary overheat protection and preventing safety accidents such as insulation breakdown and fire caused by winding overheating from the root. Please see Figure 4 The cooling component 6 includes a cooling fan 601. One end of the cooling fan 601 is connected to two wires 602. The end of the wires 602 away from the cooling fan 601 is connected to a first rectangular connecting block 603. The surface of the first rectangular connecting block 603 facing the cooling fan 601 has a rectangular groove 604. The inner cavities of the two sides of the first rectangular connecting block 603 facing the cooling fan 601 have first sliding grooves 605. A fixing component 606 is installed in the inner cavity of each first sliding groove 605. Please see Figure 6The detection component 7 includes a detection mechanism 701, a condensation component 702 connected to the outer surface of the detection mechanism 701, and a circular frame 703 connected to the outer side of the condensation component 702, and the circular frame 703 is made of heat insulation material.

[0020] Specifically, by installing the detection component 7 next to the transformer winding, the heat generated by the winding can be quickly transferred to the circular cavity 704 through heat conduction. When the winding temperature exceeds 120°C, the vaporization rate of propylene glycol increases rapidly, and the vapor pressure rises rapidly, pushing the first circular sliding block 706 to rise. Through the L-shaped connecting rod 711, the second connecting block 712 is driven to precisely connect with the fixing component 606 of the cooling component 6, quickly forming a conductive circuit to start the cooling fan 601, achieving first-level overheat protection. The entire triggering process does not need to rely entirely on external power, avoiding the protection blind spot of single electronic control triggering, thereby improving the response speed and timely curbing the rising trend of winding temperature. 1,2-Propanediol itself is low in toxicity and non-corrosive. The vapor composition produced by its vaporization is the same as that of liquid 1,2-propanediol. It does not decompose or produce harmful byproducts.

[0021] Please see Figure 5 The fixing component 606 includes a fixing block 607. A circular guide rod 608 is connected to one end of the fixing block 607 away from the rectangular groove 604. A second sliding groove 610 is provided in the inner cavity of the circular guide rod 608. A first circular connecting block 611 is connected to the inner cavity of the second sliding groove 610. An electric telescopic rod 612 is connected to one end of the first circular connecting block 611 away from the fixing block 607. A return spring 609 is sleeved on the outer side of the circular guide rod 608. The end of the fixing block 607 facing the rectangular groove 604 is arc-shaped.

[0022] Please see Figure 7 and Figure 8 The detection mechanism 701 includes a circular cavity 704, with a first circular frame 705 connected to the upper end of the circular cavity 704. A first circular sliding block 706 is connected to the inner cavity of the upper end of the first circular frame 705. Several first air leakage holes 707 are opened on the surface of the first circular sliding block 706, and a lifting rod 708 is connected to the top surface of the first circular sliding block 706. The circular cavity 704 is made of a thermally conductive material. An infrared sensor is installed in the inner cavity of the first circular frame 705. The infrared sensor detects the volume of propylene glycol liquid in the inner cavity of the circular cavity 704 in real time. Since propylene glycol may be slightly lost during long-term cyclic use, when the volume of propylene glycol liquid drops to a preset threshold, the infrared sensor sends a control signal to control the liquid storage chamber 3 to deliver propylene glycol liquid into the circular cavity 704 through the infusion tube 4 until the propylene glycol liquid level in the circular cavity 704 returns to the initial standard position, ensuring the triggering sensitivity and working stability of the detection component 7.

[0023] Please see Figure 7 and Figure 8 A circular limiting block 709 is connected to the upper surface of the lifting rod 708, and an annular sealing block 710 is connected to the lower surface of the circular limiting block 709. An L-shaped connecting rod 711 is connected to the top of the lifting rod 708. A second connecting block 712 is connected to the end surface of the L-shaped connecting rod 711 facing the fixing component 606. Fixing grooves 713 are provided on both ends of the second connecting block 712, and the top of the second connecting block 712 has a triangular structure. The initial position of the second connecting block 712 is below the fixing component 606.

[0024] Please see Figure 7 and Figure 8 The upper surface of the first circular frame 705 is provided with a plurality of second air leakage holes 714, and an annular sealing frame 715 is connected to the outside of the second air leakage holes 714, and an annular sealing groove 716 is provided on the top surface of the first circular frame 705.

[0025] Please see Figure 7 and Figure 8 The first vent 707 is conical, with its radius gradually decreasing from the bottom to the top. The inner cavity of the circular cavity 704 is filled with propylene glycol. The annular sealing groove 716 fits into the annular sealing block 710, the fixing groove 713 fits into the fixing block 607, and the second connecting block 712 fits into the rectangular groove 604. When the fixing block 607 overlaps with the fixing groove 713, the wire 602, the two fixing blocks 607, and the second connecting block 712 will form a circuit, thereby activating the cooling fan 601 to perform cooling operations. The bottom radius of the first vent 707 is larger than its top radius, which can slow down the steam flow rate and avoid abnormal pressure.

[0026] Please see Figure 9 The condensing assembly 702 includes a spiral condensing tube 717, with a feed inlet 718 at the top of the spiral condensing tube 717, and sealing assemblies 719 connected to both sides of the end of the spiral condensing tube 717 away from the feed inlet 718.

[0027] Specifically, through the spiral condenser tube 717 design of the condenser assembly 702, the vapor generated by the vaporization of propylene glycol can be quickly condensed into liquid. After the condensate accumulates to a certain weight, it can push the semi-arc sealing block 720 of the sealing assembly 719 to open, and flow back into the circular cavity 704 for reuse, realizing a closed-loop circulation of the heat triggering medium. There is no need to frequently replenish the medium, which greatly reduces maintenance costs and operational complexity. At the same time, 1,2-propanediol is used as the heat triggering medium because it is non-corrosive, does not easily decompose, and does not produce harmful gases during use, thus avoiding corrosion of the internal components of the transformer.

[0028] Please see Figure 10 The sealing assembly 719 includes a semi-circular sealing block 720. A third connecting block 721 is connected to the surface of the semi-circular sealing block 720 facing the feed port 718. A slanted return spring 722 is connected to the surface of the third connecting block 721 away from the semi-circular sealing block 720. The circular frame 703 on the outside of the detection assembly 7 is made of heat-insulating material, which can effectively isolate the heat generated by the transformer winding from spreading to the outside, ensuring that the heat of propylene glycol is concentrated and improving the accuracy of temperature triggering.

[0029] Specifically, through the linkage structure and sealing design of the detection component 7 and the cooling component 6, the triangular structure at the top of the second connecting block 712 facilitates precise embedding into the rectangular groove 604. The fitting design of the fixing block 607 and the fixing groove 713 can quickly realize the switching on and off of the conductive circuit, ensuring that the cooling fan 601 starts and stops in time. The conical first vent hole 707 can slow down the steam flow rate and avoid abnormal pressure. The setting of the annular sealing frame 715 improves the sealing performance of steam transportation and prevents trigger failure caused by steam leakage. The sealing component 719, composed of the semi-arc sealing block 720 and the inclined return spring 722, can realize the orderly return and sealing of condensate, further ensuring the stability of the propylene glycol cycle.

[0030] The feed inlet 718 is connected to the annular sealing frame 715, and the lower end of the spiral condenser tube 717 is connected to the circular cavity 704.

[0031] Specifically, the detection component 7 responds in real time to changes in the transformer winding temperature, and the thermal vaporization characteristics of 1,2-propanediol trigger the cooling component 6 to start. This, in conjunction with the temperature sensor, enables multi-stage overheat protection. At the same time, the condensation component 702 enables the recycling of propylene glycol, ensuring the long-term stable operation of the transformer 5.

[0032] Working principle: When transformer 5 is working normally, its internal windings continuously generate heat. According to the operating standards for amorphous alloy dry-type distribution transformers, the normal operating temperature of the windings must be maintained at 120℃ or below. Since the detection component 7 is installed next to the transformer windings, and the circular cavity 704 in the detection mechanism 701 is made of thermally conductive material, the heat generated by the windings is quickly transferred to the interior of the circular cavity 704 through thermal conduction, continuously heating the 1,2-propanediol liquid contained within the cavity. Under normal operating conditions with a winding temperature ≤120℃, propylene glycol will vaporize slightly upon heating, generating steam. This steam will be slowly transported to the upper inner cavity of the first circular frame 705 through several conical first vent holes 707 on the surface of the first circular sliding block 706. Then, it will enter the annular sealing frame 715, which communicates with the second vent holes 714, through several second vent holes 714 on the upper surface of the first circular frame 705. Since the annular sealing frame 715 is connected to the feed inlet 718 at the top of the spiral condenser tube 717 of the condenser assembly 702, the steam will further enter the spiral... Inside the condenser tube 717, under the condensing action of the spiral condenser tube 717, the vapor rapidly condenses into 1,2-propanediol liquid. The condensed liquid flows into the inner cavity of the sealing component 719 at the lower end of the spiral condenser tube 717. At this time, the weight of the condensed 1,2-propanediol liquid is less than the restoring force of the inclined return spring 722 in the sealing component 719. The inclined return spring 722 maintains its initial state, pushing the third connecting block 721 and the semi-arc sealing block 720 to fit tightly together, thereby achieving a seal at the lower end of the spiral condenser tube 717, preventing the condensate from flowing back prematurely, and ensuring the stable operation of the condensation process. When transformer 5 operates under high load for a long time, or when abnormal operating conditions occur causing the winding temperature to exceed 120°C, the heat generated by the winding will increase significantly, and the heat transferred to the circular cavity 704 will also increase accordingly. This will cause the propylene glycol in the circular cavity 704 to be heated more intensely, the vaporization rate to accelerate, and the steam production to increase sharply. At this time, the amount of steam generated by propylene glycol is much greater than the exhaust capacity of the first vent hole 707, which will cause the steam pressure in the sealed space formed by the circular cavity 704 and the first circular frame 705 to continue to rise, forming an upward thrust acting on the first circular sliding block 706. Under the action of this thrust, the first circular sliding block 706 slides upward along the inner cavity of the first circular frame 705 until the top of the first circular sliding block 706 is in close contact with the top of the inner cavity of the first circular frame 705. At this time, the second vent hole 714 maximizes the steam discharge efficiency, ensuring that the steam smoothly enters the spiral condenser tube 717 for condensation. As the first circular sliding block 706 moves upward, the lifting rod 708 connected to its top moves upward synchronously, causing the L-shaped connecting rod 711 at the top of the lifting rod 708 and the second connecting block 712 to move upward synchronously. Since the initial position of the second connecting block 712 is below the fixing component 606, and its top is triangular, it is easy to accurately guide it into the rectangular groove 604. When the first circular sliding block 706 moves to the top of the inner cavity of the first circular frame 705, the second connecting block 712 is exactly in perfect fit with the rectangular groove 604 opened on the surface of the first rectangular connecting block 603 in the cooling component 6. At this time, the fixing grooves 713 opened on both ends of the second connecting block 712 are in perfect fit with the first rectangular connecting block 603. The fixing block 607 in the slide 605 is precisely aligned. Under the elastic thrust of the return spring 609, the fixing block 607 moves towards the rectangular groove 604 and is inserted into the fixing groove 713, thus achieving a fixed connection between the second connecting block 712 and the first rectangular connecting block 603. Since the fixing block 607 is electrically connected to the wire 602 and the second connecting block 712 is made of conductive material, when the fixing block 607 is inserted into the fixing groove 713, the wire 602, the two fixing blocks 607 and the second connecting block 712 form a complete conductive circuit. The cooling fan 601 is powered on and starts to force the transformer winding to cool down, preventing the winding temperature from rising further and achieving first-level overheat protection. While the cooling fan 601 is working, the vapor in the spiral condenser tube 717 continuously condenses into propylene glycol liquid. As the condensate accumulates, the liquid weight gradually increases. When the liquid weight exceeds the reset force of the inclined return spring 722, it will push the semi-circular sealing block 720 to rotate towards the circular cavity 704, releasing the sealing state of the sealing component 719. The condensed propylene glycol liquid flows back into the circular cavity 704 through the lower end of the spiral condenser tube 717, realizing the recycling of propylene glycol and avoiding waste of reagents. After the condensate has flowed back, the liquid weight decreases, the inclined return spring 722 returns to its original position, and pushes the semi-circular sealing block 720 to reseal the lower end of the spiral condenser tube 717, ensuring that subsequent condensation work proceeds normally. When the cooling fan 601 continues to work and the winding temperature drops to 120°C or below, the temperature sensor detects that the temperature has reached the target and immediately sends a control signal to start the electric telescopic rod 612 in the fixed assembly 606 to retract. When the electric telescopic rod 612 retracts, it drives the first circular connecting block 611 to move away from the rectangular groove 604 along the second slide groove 610, thereby pulling the circular guide rod 608 and the fixed block 607 to move synchronously, so that the fixed block 607 is disengaged from the fixed groove 713, the fixed connection between the second connecting block 712 and the first rectangular connecting block 603 is released, the conductive circuit is broken, and the cooling fan 601 stops working. As the winding temperature drops to the normal range, the vaporization rate of propylene glycol in the circular cavity 704 slows down, the steam production decreases, and the steam pressure gradually decreases. When the steam pressure is insufficient to support the first circular sliding block 706, the first circular sliding block 706 slides downward along the inner cavity of the first circular frame 705 under its own gravity, causing the lifting rod 708, the L-shaped connecting rod 711, and the second connecting block 712 to move downward synchronously and return to the initial position. At this time, the infrared sensor installed in the inner cavity of the first circular frame 705 detects that the detection mechanism 701 has returned to its original position and immediately sends a control signal to start the electric telescopic rod 612 to perform a reset operation. The electric telescopic rod 612 extends and pushes the fixed block 607 back to the initial position with the cooperation of the reset spring 609, preparing for the next temperature trigger. This concludes all operations.
