Description

Technical Field

[0001] The present invention relates to the technical field of double-star rectifier transformers, and specifically to a double-star rectifier transformer for a low-loss hydrogen production system. Background Art

[0002] Electrolytic water hydrogen production requires long-term stable high-power direct current. Traditional rectification schemes have problems such as harmonic pollution, low efficiency, and large equipment volume. The double-star rectifier transformer can significantly reduce the harmonic content of the input current and improve grid compatibility through special winding connections. By adopting a split core or wound core structure, the no-load loss is reduced, which is 30%-50% less than that of the traditional laminated core. High-purity electrolytic copper wires are used, combined with transposed wire and foil winding technologies. The low-loss of the double-star rectifier transformer is the key technical support for the transformation of the hydrogen production system from high energy consumption to high efficiency and low carbon. Its technological innovation and industrial application will directly promote the large-scale development of the green hydrogen economy. However, the transformer oil in the existing double-star rectifier transformer cannot be quickly cooled and evenly diffused in the box, reducing the cooling efficiency and increasing hydrogen production losses.

[0003] The defects of the existing double-star rectifier transformer are as follows: 1. Patent document CN102403104A discloses a double-star rectifier transformer, "including an upper clamping piece, a lower clamping piece located below the upper clamping piece, a coil clamped between the upper clamping piece and the lower clamping piece, multiple screw rods, and a balance reactor. The upper end of the screw rod is connected with an upper locking nut, and the upper locking nut abuts against the upper surface of the upper clamping piece. The lower end of the screw rod is connected with a lower locking nut, and the lower locking nut abuts against the lower surface of the lower clamping piece. The screw rod is also provided with an upper limit nut for restricting the downward movement of the upper clamping piece and a lower limit nut for restricting the upward movement of the lower clamping piece. The upper limit nut abuts against the lower surface of the upper clamping piece, and the lower limit nut abuts against the upper surface of the lower clamping piece. By setting an upper limit nut for restricting the downward movement of the upper clamping piece and a lower limit nut for restricting the upward movement of the lower clamping piece on the screw rod, the distance between the upper clamping piece and the lower clamping piece can be effectively controlled, making the transformer an effective whole, protecting the coil, and having a relatively simple structure and low manufacturing cost", but the transformer oil in the existing double-star rectifier transformer cannot be quickly cooled and evenly diffused in the box, reducing the cooling efficiency and increasing hydrogen production losses; 2. Patent document CN106653313A discloses a double-star radial split dry-type rectifier transformer, "including two low-voltage windings and one high-voltage winding. The two low-voltage windings have the same number of turns and are simultaneously wound into a radially split first low-voltage winding, and the first low-voltage winding corresponds to the one high-voltage winding. The advantages of the present invention are that since the two low-voltage windings have the same number of turns, the copper foils of the two coils are insulated and wound simultaneously, and wound into a radial split. Since the two low-voltage windings are wound together, the casting equipment and casting time can be reduced; at the same time, one less group of high-voltage windings is wound, which also saves workload", but the existing double-star rectifier transformer has reduced heat dissipation efficiency due to the rapid replacement and cleaning of the filter screen; 3. Patent document CN107424787B discloses a double-star half-wave in-phase inverse parallel rectifier transformer, "its a1 vertical copper bar and a5 vertical copper bar are arranged vertically opposite to each other, x2 vertical copper bar and x6 vertical copper bar are arranged vertically opposite to each other, a3 vertical copper bar and a7 vertical copper bar are arranged vertically opposite to each other, x4 vertical copper bar and x8 vertical copper bar are arranged vertically opposite to each other. b1 vertical copper bar and b5 vertical copper bar are arranged vertically opposite to each other, y2 vertical copper bar and y6 vertical copper bar are arranged vertically opposite to each other, b3 vertical copper bar and b7 vertical copper bar are arranged vertically opposite to each other, y4 vertical copper bar and y8 vertical copper bar are arranged vertically opposite to each other. c1 vertical copper bar and c5 vertical copper bar are arranged vertically opposite to each other, z2 vertical copper bar and z6 vertical copper bar are arranged vertically opposite to each other, c3 vertical copper bar and c7 vertical copper bar are arranged vertically opposite to each other, z4 vertical copper bar and z8 vertical copper bar are arranged vertically opposite to each other. The present invention can be applied to a transformer with a low-voltage current above 40 kA", but the existing double-star rectifier transformer has reduced heat dissipation effect due to the inability to quickly drop the sundries on the surface of the heat sink; 4. Patent document CN206148232U discloses a three-phase five-column six-phase double-star rectifier transformer, "including a fastening device and an iron core frame connected to each other. Between the two side yokes of the iron core frame, there are three iron core columns both connected to the upper iron yoke and the lower iron yoke. On the iron core columns, there are disk windings both connected to the output row and the input row. The disk windings include a number of sub-windings arranged in sequence from top to bottom. The sub-windings include a first low-voltage winding, a high-voltage winding, and a second low-voltage winding arranged in sequence from top to bottom. The output row includes a first output row, a second output row, and a third output row arranged in sequence. The first low-voltage winding is connected to the first output row, the high-voltage winding is connected to the third output row, and the second low-voltage winding is connected to the second output row. The present utility model has a clever concept and is easy to operate, solving the technical problems of difficult heat dissipation, long installation and maintenance time, and large volume in the existing cylindrical winding transformers; and the single and fixed connection method of the coils in the disk winding transformers", but the existing double-star rectifier transformer cannot automatically adjust the cooling efficiency, increasing the hydrogen production loss.

[0014] Preferably, the usage method of this transformer includes the following steps: Step S1: The oil pump starts to suck the transformer oil in the box into the continuous "bow"-shaped pipe. At this time, the first blower starts to generate wind and blows it onto the surface of the continuous "bow"-shaped pipe, causing the transformer oil in the continuous "bow"-shaped pipe to cool down. The cooled transformer oil re-enters the box through the discharge head. At this time, the first motor rotates to drive the first striking head to rotate. The rotation of the first striking head drives the T-shaped frame to move. The movement of the T-shaped frame drives the first spring to move. The movement of the first spring causes the T-shaped frame to drive the pick-up rod to move. The pick-up rod moves to lift the transformer oil discharged by the discharge head, making it evenly spread in the box, realizing the function of quickly cooling the transformer oil in the double-star rectifier transformer, evenly spreading it in the box, improving the cooling efficiency, and reducing the hydrogen production loss; Step S2: Pull the L-shaped pull rod to drive the second cylinder to move. The movement of the second cylinder causes the L-shaped pull rod to drive the support plate to move. The movement of the support plate drives the second spring to move. The movement of the second spring causes the L-shaped pull rod to drive the pressing head to move away from the outer wall of the filter screen. At this time, pull the filter screen and remove it from the first port. After the filter screen is removed, the staff cleans it and then puts it back into the first port. At this time, release the L-shaped pull rod and press the pressing head against the outer wall of the filter screen, so that the filter screen presses against the support block for fixation, realizing the function of quickly replacing and cleaning the filter screen of the double-star rectifier transformer and improving the heat dissipation efficiency; Step S3: The electric push rod starts to drive the T-shaped cleaning head to move. While the T-shaped cleaning head is moving, the fourth motor rotates. The rotation of the fourth motor drives the third striking head to rotate. The rotation of the third striking head drives the T-shaped striking head to move. The movement of the T-shaped striking head drives the sixth spring to move. The movement of the sixth spring causes the T-shaped striking head to strike on the surface of the force-bearing plate to make it vibrate. The vibration of the force-bearing plate drives the T-shaped cleaning head to vibrate. While the T-shaped cleaning head is vibrating, it moves in the gaps between the heat sinks, scraping the sundries in the gaps between the heat sinks off the surface of the heat sinks to improve the heat dissipation effect, realizing the function of quickly scraping off the sundries on the surface of the heat sinks of the double-star rectifier transformer and improving the heat dissipation effect; Step S4: When the processing module detects a low temperature state, the processing module controls the cooling module not to start. After the cooling module does not start, the temperature sensor continuously detects the real-time working temperature data inside the transformer until the processing module detects a high temperature state or a suitable temperature state. When the processing module detects a high temperature state, the processing module controls the cooling module to increase the power. After the cooling module increases the power, the temperature sensor continuously detects the real-time working temperature data inside the transformer until the processing module detects a low temperature state or a suitable temperature state. When the processing module detects a suitable temperature state, the processing module controls the cooling module to maintain the power. After the cooling module maintains the power, the temperature sensor continuously detects the real-time working temperature data inside the transformer until the processing module detects a low temperature state or a high temperature state, realizing the function of automatically adjusting the cooling efficiency of the double-star rectifier transformer and reducing the hydrogen production loss.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In the present invention, when the oil pump is started, the transformer oil in the box body is sucked into the continuous "bow" - shaped tube. At this time, the first fan starts to generate wind and blows towards the surface of the continuous "bow" - shaped tube, causing the transformer oil in the continuous "bow" - shaped tube to cool down. The cooled transformer oil re - enters the box body through the discharge head. At this time, the first motor rotates to drive the first striking head to rotate. The rotation of the first striking head drives the T - shaped frame to move. The movement of the T - shaped frame drives the first spring to move. The movement of the first spring causes the T - shaped frame to drive the pick - up rod to move. The pick - up rod moves to pick up the transformer oil discharged by the discharge head, making it evenly spread in the box body, realizing the functions of quickly cooling the transformer oil in the double - reverse - star rectifier transformer, evenly spreading it in the box body, improving the cooling efficiency, and reducing the hydrogen production loss; 2. In the present invention, by pulling the L - shaped pull rod to drive the second cylinder to move, the movement of the second cylinder causes the L - shaped pull rod to drive the support plate to move. The movement of the support plate drives the second spring to move. The movement of the second spring causes the L - shaped pull rod to drive the pressing head to move away from the outer wall of the filter screen. At this time, pull the filter screen and move it out of the first opening. After the filter screen is removed, the staff cleans it and then puts it back into the first opening. At this time, release the L - shaped pull rod to press the pressing head towards the outer wall of the filter screen, making the filter screen press against the support block for fixation, realizing the functions of quickly replacing and cleaning the filter screen of the double - reverse - star rectifier transformer and improving the heat dissipation efficiency; 3. In the present invention, when the electric push rod is started to drive the T - shaped cleaning head to move, while the T - shaped cleaning head is moving, the fourth motor rotates. The rotation of the fourth motor drives the third striking head to rotate. The rotation of the third striking head drives the T - shaped striking head to move. The movement of the T - shaped striking head drives the sixth spring to move. The movement of the sixth spring causes the T - shaped striking head to strike on the surface of the force - receiving plate to make it vibrate. The vibration of the force - receiving plate drives the T - shaped cleaning head to vibrate. While the T - shaped cleaning head is vibrating, it moves in the gaps between the heat sinks, scraping the sundries in the gaps between the heat sinks off the surface of the heat sinks to improve the heat dissipation effect, realizing the functions of quickly scraping off the sundries on the surface of the heat sinks of the double - reverse - star rectifier transformer and improving the heat dissipation effect; 4. In the present invention, when the processing module detects a low - temperature state, the processing module controls the cooling module not to start. After the cooling module does not start, the temperature sensor continuously detects the real - time working temperature data of the transformer until the processing module detects a high - temperature state or a suitable - temperature state. When the processing module detects a high - temperature state, the processing module controls the cooling module to increase the power. After the cooling module increases the power, the temperature sensor continuously detects the real - time working temperature data of the transformer until the processing module detects a low - temperature state or a suitable - temperature state. When the processing module detects a suitable - temperature state, the processing module controls the cooling module to maintain the power. After the cooling module maintains the power, the temperature sensor continuously detects the real - time working temperature data of the transformer until the processing module detects a low - temperature state or a high - temperature state, realizing the functions of automatically adjusting the cooling efficiency of the double - reverse - star rectifier transformer and reducing the hydrogen production loss.

The electric push rod 28 moves through the fifth opening 29. The third striking head 36 is located on one side of the T-shaped striking head 32. The T-shaped impurity removal head 30 moves in the gap between the heat sinks 2. When the electric push rod 28 is started, it drives the T-shaped impurity removal head 30 to move. While the T-shaped impurity removal head 30 is moving, the fourth motor 35 rotates. The rotation of the fourth motor 35 drives the third striking head 36 to rotate. The rotation of the third striking head 36 drives the T-shaped striking head 32 to move. The movement of the T-shaped striking head 32 drives the sixth spring 33 to move. The movement of the sixth spring 33 causes the T-shaped striking head 32 to strike the surface of the force-bearing plate 34 to make it vibrate. The vibration of the force-bearing plate 34 drives the T-shaped impurity removal head 30 to vibrate. While the T-shaped impurity removal head 30 is vibrating, it moves in the gap between the heat sinks 2, scraping the sundries in the gap between the heat sinks 2 from the surface of the heat sinks 2 to improve the heat dissipation effect, realizing the function of quickly dropping the sundries on the surface of the heat sinks 2 of the double-star rectifier transformer to improve the heat dissipation effect.

[0024] Example 4: Please refer to Figure 2 , Figure 9 and Figure 10, an embodiment provided by the present invention: The temperature control module includes a temperature sensor 38 and a processing module. The processing module is installed on the outer wall of the box body 1, and the temperature sensor 38 is located on the inner wall of the box body 1. The temperature sensor 38 is electrically connected to the processing module, and the cooling module is electrically connected to the processing module. The temperature sensor 38 is used to detect the real-time working temperature data inside the transformer. The processing module stores the appropriate working temperature data inside the transformer, and the appropriate working temperature data is 85-115°C. The real-time working temperature data inside the transformer is transmitted into the processing module. The processing module compares the real-time working temperature data inside the transformer with the appropriate working temperature data inside the transformer. When the real-time working temperature data inside the transformer is lower than the appropriate working temperature data inside the transformer, it is set as the low-temperature state. When the real-time working temperature data inside the transformer is higher than the appropriate working temperature data inside the transformer, it is set as the high-temperature state. When the real-time working temperature data inside the transformer is within the appropriate working temperature data inside the transformer, it is set as the appropriate-temperature state. When the processing module detects the low-temperature state, the processing module controls the cooling module not to start. After the cooling module does not start, the temperature sensor 38 continuously detects the real-time working temperature data inside the transformer until the processing module detects the high-temperature state or the appropriate-temperature state. When the processing module detects the high-temperature state, the processing module controls the cooling module to increase the power. After the cooling module increases the power, the temperature sensor 38 continuously detects the real-time working temperature data inside the transformer until the processing module detects the low-temperature state or the appropriate-temperature state. When the processing module detects the appropriate-temperature state, the processing module controls the cooling module to maintain the power. After the cooling module maintains the power, the temperature sensor 38 continuously detects the real-time working temperature data inside the transformer until the processing module detects the low-temperature state or the high-temperature state, realizing the function of automatically adjusting the cooling efficiency of the double-star rectifier transformer to reduce the hydrogen production loss.

[0025] The usage method of this transformer includes the following steps: Step S1, the oil pump 7 starts to suck the transformer oil in the box body 1 into the continuous "bow" - shaped tube 8. At this time, the first fan 6 starts to generate wind and blows towards the surface of the continuous "bow" - shaped tube 8, so that the transformer oil in the continuous "bow" - shaped tube 8 is cooled. The cooled transformer oil re - enters the box body 1 through the discharge head 9. At this time, the first motor 11 rotates to drive the first hitting head 12 to rotate. The rotation of the first hitting head 12 drives the T - shaped frame 14 to move. The movement of the T - shaped frame 14 drives the first spring 15 to move. The movement of the first spring 15 makes the T - shaped frame 14 drive the pick - rod 16 to move. The pick - rod 16 moves to lift the transformer oil discharged from the discharge head 9, so that it evenly diffuses in the box body 1, realizing the function of quickly cooling the transformer oil in the double - star rectifier transformer, evenly diffusing it in the box body 1, improving the cooling efficiency and reducing the hydrogen production loss. Step S2: Pull the L-shaped pull rod 21 to drive the second cylinder 24 to move. The movement of the second cylinder 24 causes the L-shaped pull rod 21 to drive the support plate 26 to move. The movement of the support plate 26 drives the second spring 25 to move. The movement of the second spring 25 causes the L-shaped pull rod 21 to drive the pressing head 22 to move away from the outer wall of the filter screen 17. At this time, pull the filter screen 17 and remove it from the first opening 18. After the filter screen 17 is removed, the staff cleans it and then puts it back into the first opening 18. At this time, release the L-shaped pull rod 21 and press the pressing head 22 against the outer wall of the filter screen 17, so that the filter screen 17 is pressed against the support block 19 for fixation, realizing the function of quickly replacing and cleaning the filter screen 17 of the double reverse star rectifier transformer to improve the heat dissipation efficiency; Step S3: Start the electric push rod 28 to drive the T-shaped impurity cleaning head 30 to move. While the T-shaped impurity cleaning head 30 is moving, the fourth motor 35 rotates. The rotation of the fourth motor 35 drives the third hitting head 36 to rotate. The rotation of the third hitting head 36 drives the T-shaped hitting head 32 to move. The movement of the T-shaped hitting head 32 drives the sixth spring 33 to move. The movement of the sixth spring 33 causes the T-shaped hitting head 32 to hit the surface of the force receiving plate 34 to make it vibrate. The vibration of the force receiving plate 34 drives the T-shaped impurity cleaning head 30 to vibrate. While the T-shaped impurity cleaning head 30 is vibrating, it moves in the gap between the heat sinks 2, and scrapes the sundries in the gap between the heat sinks 2 from the surface of the heat sinks 2 to improve the heat dissipation effect, realizing the function of quickly dropping the sundries on the surface of the heat sinks 2 of the double reverse star rectifier transformer to improve the heat dissipation effect; Step S4: When the processing module detects a low temperature state, the processing module controls the cooling module not to start. After the cooling module does not start, the temperature sensor 38 continuously detects the real-time working temperature data inside the transformer until the processing module detects a high temperature state or a suitable temperature state. When the processing module detects a high temperature state, the processing module controls the cooling module to increase the power. After the cooling module increases the power, the temperature sensor 38 continuously detects the real-time working temperature data inside the transformer until the processing module detects a low temperature state or a suitable temperature state. When the processing module detects a suitable temperature state, the processing module controls the cooling module to maintain the power. After the cooling module maintains the power, the temperature sensor 38 continuously detects the real-time working temperature data inside the transformer until the processing module detects a low temperature state or a high temperature state, realizing the function of automatically adjusting the cooling efficiency of the double reverse star rectifier transformer to reduce the hydrogen production loss.

[0026] Working principle: When the oil pump 7 starts, it sucks the transformer oil in the box body 1 into the continuous "bow" - shaped pipe 8. At this time, the first blower 6 starts to generate wind and blows towards the surface of the continuous "bow" - shaped pipe 8, causing the transformer oil in the continuous "bow" - shaped pipe 8 to cool down. The cooled transformer oil re - enters the box body 1 through the discharge head 9. At this time, the first motor 11 rotates to drive the first striking head 12 to rotate. The rotation of the first striking head 12 drives the T - shaped frame 14 to move. The movement of the T - shaped frame 14 drives the first spring 15 to move. The movement of the first spring 15 causes the T - shaped frame 14 to drive the pick - up rod 16 to move. The pick - up rod 16 moves to lift the transformer oil discharged from the discharge head 9, making it evenly spread in the box body 1, realizing the function of quickly cooling the transformer oil in the double - reverse star rectifier transformer, evenly spreading it in the box body 1, improving the cooling efficiency, and reducing the hydrogen production loss. Pull the L - shaped pull rod 21 to drive the second cylinder 24 to move. The movement of the second cylinder 24 causes the L - shaped pull rod 21 to drive the support plate 26 to move. The movement of the support plate 26 drives the second spring 25 to move. The movement of the second spring 25 causes the L - shaped pull rod 21 to drive the pressing head 22 to move away from the outer wall of the filter screen 17. At this time, pull the filter screen 17 to move it out of the first opening 18. After the filter screen 17 is removed, the staff cleans it and then puts it back into the first opening 18. At this time, release the L - shaped pull rod 21 to press the pressing head 22 against the outer wall of the filter screen 17, making the filter screen 17 press against the support block 19 for fixation, realizing the function of quickly replacing and cleaning the filter screen 17 of the double - reverse star rectifier transformer and improving the heat dissipation efficiency. The electric push rod 28 starts to drive the T - shaped cleaning head 30 to move. While the T - shaped cleaning head 30 is moving, the fourth motor 35 rotates. The rotation of the fourth motor 35 drives the third striking head 36 to rotate. The rotation of the third striking head 36 drives the T - shaped striking head 32 to move. The movement of the T - shaped striking head 32 drives the sixth spring 33 to move. The movement of the sixth spring 33 causes the T - shaped striking head 32 to strike the surface of the stress plate 34 to make it vibrate. The vibration of the stress plate 34 drives the T - shaped cleaning head 30 to vibrate. While the T - shaped cleaning head 30 is vibrating, it moves in the gap between the heat sinks 2, scraping the sundries in the gap between the heat sinks 2 off the surface of the heat sinks 2 to improve the heat dissipation effect, realizing the function of quickly scraping off the sundries on the surface of the heat sinks 2 of the double - reverse star rectifier transformer and improving the heat dissipation effect. When the processing module detects a low - temperature state, the processing module controls the cooling module not to start. After the cooling module does not start, the temperature sensor 38 continuously detects the real - time working temperature data of the transformer until the processing module detects a high - temperature state or a suitable - temperature state. When the processing module detects a high - temperature state, the processing module controls the cooling module to increase the power. After the cooling module increases the power, the temperature sensor 38 continuously detects the real - time working temperature data of the transformer until the processing module detects a low - temperature state or a suitable - temperature state. When the processing module detects a suitable - temperature state, the processing module controls the cooling module to maintain the power. After the cooling module maintains the power, the temperature sensor 38 continuously detects the real - time working temperature data of the transformer until the processing module detects a low - temperature state or a high - temperature state.The function of automatically adjusting the cooling efficiency and reducing the hydrogen production loss of the double-anti-star rectifier transformer is realized.
