Description

Technical Field

[0001] This invention relates to the field of dry-type rectifier voltage regulating transformer technology, and more particularly to a dry-type rectifier voltage regulating transformer. Background Technology

[0002] Dry-type rectifier voltage regulating transformers employ epoxy resin casting or vacuum impregnation dry-type insulation structures, are oil-free, fireproof, and explosion-proof. They integrate voltage regulating windings and multi-pulse rectifier windings, allowing for precise adjustment of AC output voltage and conversion to stable DC power with a rectifier. Utilizing H-class high-temperature resistant insulation, they possess strong overload and impact resistance. An internal phase-shifting structure suppresses grid harmonics, resulting in low-noise operation, oil-leakage-free maintenance, and flexible installation. They are widely applicable to high-power DC power supply scenarios such as water electrolysis for hydrogen production, electroplating and metallurgy, rail transit traction, and high-voltage frequency conversion. They can adapt to load fluctuations to achieve stable DC voltage output. Furthermore, their high short-circuit impedance design limits commutation inrush current, making them safe, environmentally friendly, and suitable for harsh environments such as indoor, underground, and high-risk chemical plants.

[0003] During use, existing dry-type rectifier voltage regulating transformers require regular maintenance of the high-voltage connecting plates. Since existing dry-type rectifier voltage regulating transformers are not convenient for automatic maintenance of the high-voltage connecting plates, manual maintenance is required.

At the same time, the electric push rod can drive the grinding plate connected to the spring to move up and down reciprocally, automatically grinding and maintaining the contact surface of the high-voltage connecting piece.

[0017] 2. By setting up a storage tank and a grease application component, the storage tank can be continuously pressurized and inflated as the processing component moves up and down. This allows the conductive grease in the storage tank to be automatically sprayed out by the grease application component to automatically apply the grease to the contact surface of the high-voltage connecting piece after processing. This eliminates the need for manual application of conductive grease, ensures even application and controllable dosage, and completes the protective process simultaneously after grinding and rust removal. This avoids problems such as uneven thickness and missed application caused by manual application, which can accelerate oxidation of the connecting piece and increase contact resistance. It continuously ensures the conductivity of the high-voltage connecting piece and extends its service life.

[0018] 3. By setting transmission gears on the processing component, the processing component can move up and down while retracting and resetting, automatically completing the application of conductive grease. At the same time, by setting a triangular plate on the fixed frame, the cover on the processing seat can be automatically moved up and closed after the high-voltage connecting piece is maintained, protecting the internal structure and ensuring the effectiveness of subsequent maintenance.

[0030] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0031] like Figures 1-10 The dry-type rectifier voltage regulating transformer shown includes a mounting frame 1, on which a transformer 2 is mounted and fixed. A fixed frame 3 is fixedly connected to the mounting frame 1. A movable frame 4 is slidably fitted onto the fixed frame 3. A processing seat 5 is fixedly connected to the movable frame 4. A movable plate 6 is disposed inside the processing seat 5. A disassembly and assembly component 7 for automatically disassembling and assembling the high-voltage connecting pieces on the transformer 2 is disposed on one side of the movable plate 6. A processing component 8 for maintaining the contact surface of the high-voltage connecting pieces is fixedly connected to the inner wall of the bottom end of the processing seat 5. A processing component 8 is provided above the processing component 8. The processing unit 8 is equipped with a grease applicator 9 for applying conductive grease to the contact surface of the high-voltage connecting piece. A storage tank 10 is fixedly connected to the inner wall of the top of the processing base 5. The processing unit 8 includes a movable frame 801. An electric push rod is fixedly connected between one side of the top of the movable frame 801 and the inner wall of the processing base 5. A grinding plate 802 is slidably fitted through one side of the movable frame 801. The grinding plate 802 abuts against the contact surface of the high-voltage connecting piece. Multiple springs 803 are fixedly connected between the grinding plate 802 and the movable frame 801. Both the upper and lower ends of the grinding plate 802 are provided with inclined surfaces.

[0032] By setting up the processing component 8, the high-voltage connecting piece on the transformer 2 can be automatically removed and retracted into the processing seat 5 using the disassembly and assembly component 7. At the same time, the electric push rod can drive the grinding plate 802 connected to the spring 803 to move up and down reciprocally, automatically grinding and maintaining the contact surface of the high-voltage connecting piece. This eliminates the need for manual close-range high-altitude operations, completely avoiding the safety hazards of electric shock and burns. The grinding operation is uniform and thorough, effectively eliminating the contact heating, arcing and short circuit problems caused by incomplete manual cleaning and rust removal, and greatly improving the level of automated operation and maintenance and overall practicality of the equipment.

[0033] like Figure 4 As shown, a lead screw 301 is rotatably connected through the fixed frame 3. A motor 302 is fixedly connected to one end of the lead screw 301. The motor 302 is fixedly connected to the fixed frame 3. The lead screw 301 is threadedly connected to the bottom end of the movable frame 4. Triangular plates 303 are fixedly connected to both ends of the fixed frame 3.

[0034] Motor 302 precisely drives the moving frame 4 to slide horizontally along the fixed frame 3 via threaded transmission, accurately aligning it with the working position of the high-voltage connecting piece of transformer 2.

[0035] like Figure 5 As shown, a cover 501 is slidably fitted at the opening on one side of the processing seat 5. Contact rods 502 are fixedly connected to both sides of the top of the cover 501. The bottom of the contact rods 502 is slidably in contact with the inclined surface of the triangular plate 303.

[0036] When the processing seat 5 is moved to both sides of the fixed frame 3 for parking, the cover 501 can be automatically moved up and closed by the action of the triangular plate 303.

[0037] like Figure 6 As shown, electric push rods are fixedly connected to the upper and lower ends of one side of the movable plate 6 and the inner wall of the processing seat 5. A transmission rod 601 is rotatably connected through the middle of the movable plate 6. A transmission groove 602 is provided on the outer wall of the transmission rod 601. The transmission groove 602 is composed of two parts: a straight line and a spiral. A guide rod 603 is slidably fitted on the inner wall of the transmission groove 602. One end of the guide rod 603 is fixedly connected to the inner wall of the processing seat 5.

[0038] The spiral part of the transmission groove 602 enables the transmission rod 601 to drive the disassembly and assembly component 7 to rotate from the angle of the high-pressure connecting piece to a vertical state, which facilitates maintenance and handling.

[0039] like Figure 7 As shown, the assembly / disassembly component 7 includes a rotating frame 701. One end of the rotating frame 701 is fixedly connected to one end of the transmission rod 601. Both ends of the rotating frame 701 are fixedly connected to a second motor 702. The output end of the second motor 702 passes through the rotating frame 701 and is fixedly connected to an internal hexagonal sleeve 703. An electric push rod 3 is fixedly connected through the middle of the rotating frame 701. The output end of the electric push rod 3 is fixedly connected to a U-shaped frame 704.

[0040] The 703 internal hex socket has a magnet installed inside, which can magnetically attract the fastening bolts of the high-voltage connecting plate, ensuring the stability of the fastening bolts when removing them.

[0041] Both ends of the U-shaped frame 704 are fitted with sliding clamps 705 on their inner sides. The clamps 705 have grooves that are compatible with the high-voltage connecting pieces. The side of the clamps 705 facing the U-shaped frame 704 is fixedly connected to the U-shaped frame 704 with an electric push rod four.

[0042] The electric actuator four pushes the high-voltage connecting piece held by the clamping plate 705, causing its two ends to detach from the fastening bolts, making it easier to maintain the contact surface.

[0043] like Figure 8 As shown, a contact plate 804 is fixedly connected to the bottom of the movable frame 801, and a gear frame is fixedly connected to one side of the contact plate 804. Multiple transmission teeth 805 are rotatably connected in a linear structure inside the gear frame, and a spring 806 is fixedly connected between the transmission teeth 805 and the inner wall of the gear frame.

[0044] Spring 2 806 enables the transmission gear 805 to drive the grease application assembly 9 to automatically complete the process of moving down and up during the process of the movable frame 801 moving down and resetting.

[0045] like Figure 9 As shown, the grease application assembly 9 includes a sliding frame 901. An L-shaped rod 902 is slidably fitted on the inner wall of the sliding frame 901. The other end of the L-shaped rod 902 is rotatably connected to the inner wall of the treatment seat 5. A one-way wheel 903 is fixedly connected to the end of the L-shaped rod 902 connected to the treatment seat 5. The one-way wheel 903 is unidirectionally meshed with the transmission gear 805 for transmission. An applicator 904 is fixedly connected to the top of the sliding frame 901. A rectangular opening is provided at the bottom of the applicator 904. An output pipe 905 is fixedly connected through the inner wall of the applicator 904.

[0046] There is a certain gap between the rectangular opening at the bottom of the 904 applicator and the contact surface of the high-voltage connecting piece to ensure the thickness of the conductive grease application. The rectangular opening structure can evenly disperse the grease and ensure a smooth and regular application surface.

[0047] like Figure 10 As shown, a guide pipe 1001 is fixedly connected to the top of the storage tank 10. The other end of the guide pipe 1001 extends through the inner wall of the top of the processing seat 5 to the outside and is slidably engaged with the inner wall of the output pipe 905. An air cylinder 1002 is fixedly connected to the bottom of the storage tank 10. The output end of the air cylinder 1002 is fixedly connected to the inner wall of the bottom of the storage tank 10 through a pipe. A pressure plug 1003 is fixedly connected to the inner wall of the bottom of the air cylinder 1002. A contact frame 1004 is fixedly connected to the bottom of the pressure plug 1003. The bottom of the contact frame 1004 is in movable contact with the top of the contact plate 804.

[0048] A solenoid valve is fixedly connected to one end of the guide pipe 1001, and a one-way valve is installed in both the input and output ends of the air cylinder 1002.

[0049] Working principle: When not in use, the treatment seat 5 rests on both ends of the fixed frame 3, the contact rod 502 is in contact with the inclined surface of the triangular plate 303, and the push cover 501 moves up to close the opening of the treatment seat 5, completely sealing and protecting the internal grinding, grease application and transmission structure, preventing dust and moisture from entering, and ensuring the cleanliness and precision of the internal structure.

[0050] When transformer 2 requires maintenance of the high-voltage connecting piece, start motor 302 drives lead screw 301 to rotate, and through threaded transmission, move the moving frame 4 along the fixed frame 3, moving the processing seat 5 to the working position of the high-voltage connecting piece of transformer 2; during the movement, the contact rod 502 disengages from the limit of the triangular plate 303, and the cover 501 automatically moves down to open the working opening of the processing seat 5.

[0051] Then, the electric push rod 2 connected to the moving plate 6 inside the processing seat 5 extends, pushing the moving plate 6 and the transmission rod 601 forward. The guide rod 603 slides along the transmission groove 602. The straight section completes the horizontal alignment feed, and the spiral section drives the transmission rod 601 to rotate automatically, adjusting the angle of the disassembly and assembly component 7 to the working angle suitable for the disassembly and assembly of the high-voltage connecting piece. At the same time, the electric push rod 4 drives the two clamping plates 705 to clamp on both sides of the high-voltage connecting piece. Then, the two internal hexagon sleeves 703 are put on the fastening bolts. Then, the motor 2 702 at both ends of the rotating frame 701 drives the internal hexagon sleeves 703 to rotate and align with the fastening bolts at both ends of the high-voltage connecting piece. The bolts are fixed by magnetic attraction using the built-in magnets. The bolts are disassembled by rotating in the forward direction. During the disassembly process, the electric push rod 2 drives the moving plate 6 to reset at a constant speed, and the high-voltage connecting piece is removed.

[0052] The connecting piece is then retracted into the processing seat 5; at the same time, the transmission rod 601 is rotated and adjusted again to adjust the tilted high-pressure connecting piece to a vertical position, fully exposing the contact surface and providing a standard working surface for grinding. Then, the electric push rod three drives the U-shaped frame 704 to move, so that the two ends of the clamped high-pressure connecting piece are detached from the bolts.

[0053] Then, the processing component 8 is activated. The electric push rod inside the processing base 5 first drives the movable frame 801 to move upward, so that the grinding plate 802 contacts the high-voltage connecting piece. Then, the electric push rod drives the movable frame 801 to move up and down quickly and short distances, causing the grinding plate 802 to repeatedly grind against the contact surface of the high-voltage connecting piece. Under the elastic action of the spring 803, the grinding plate 802 adapts to the surface of the connecting piece, thoroughly removing the oxide layer, rust and attached dust impurities from the contact surface, eliminating the risk of poor contact.

[0054] Throughout the reciprocating grinding operation of the movable frame 801, the bottom contact plate 804 continuously presses against the contact frame 1004, causing the air plug 1003 to reciprocate in the air cylinder 1002 to pressurize air. This, in conjunction with the one-way valve, continuously pressurizes the storage tank 10, keeping the conductive grease in the tank under stable pressure and ready for discharge, thus providing stable power for automatic grease application.

[0055] When a single polishing process is completed and the movable frame 801 moves down to its reset position, the contact plate 804 drives the gear frame and transmission gear 805 to move down synchronously. The spring 806 pushes the transmission gear 805 to engage with the one-way wheel 903 in one direction, driving the L-shaped rod 902 to rotate. Through the sliding frame 901, the coating rack 904 moves down smoothly and then resets and moves up. At this time, the solenoid valve of the guide tube 1001 opens, and the conductive grease in a stabilizing state is evenly coated onto the fresh contact surface after polishing through the guide tube 1001 and the output tube 905 from the rectangular opening of the coating rack 904. The fixed gap precisely controls the grease thickness, achieving uniform automated grease coating protection and immediately isolating air to prevent secondary oxidation.

[0056] After the high-voltage connecting piece is maintained, the disassembly and assembly component 7 clamps the high-voltage connecting piece again to reset and align its installation position. Motor 2 702 rotates in the opposite direction to tighten the fastening bolts, completing the automatic reset and assembly of the connecting piece.
