[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0039] It should be understood that the "one embodiment" or "an embodiment" mentioned throughout the specification means that the specific features, structures, or characteristics related to the embodiment are included in at least one embodiment of the present invention. Therefore, the "in one embodiment" or "in an embodiment" that appears throughout the specification does not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics can be combined in one or more embodiments in any suitable manner.

[0040] Figure 1 is the circuit diagram of a hydrogen production power supply control device according to an embodiment of the present invention, Figure 2 is the circuit diagram of another hydrogen production power supply control device according to an embodiment of the present invention, Figure 3This is a schematic diagram of the external structure of a hydrogen production power supply control device according to an embodiment of the present utility model. As shown in Figure 1 , Figure 2 and as shown in Figure 3 , the hydrogen production power supply control device includes:

[0041] A transformer assembly 1, the transformer assembly 1 includes a voltage regulating transformer 11 and at least two rectifier transformers 12, and each rectifier transformer 12 is electrically connected to the voltage regulating transformer 11;

[0042] At least two load terminals 2, and each load terminal 2 is electrically connected to a rectifier transformer 12;

[0043] A power-off assembly 3, the power-off assembly 3 is electrically connected in the electrical connection line between each rectifier transformer 12 and the voltage regulating transformer 11, or the power-off assembly 3 is electrically connected in the electrical connection line between the load terminal 2 and the rectifier transformer 12, or the power-off assembly 3 is electrically connected in the electrical connection line between the load terminal 2 and the rectifier transformer 12 and the electrical connection line between each rectifier transformer 12 and the voltage regulating transformer 11. Among them, the power-off assembly 3 is used to disconnect the electrical connection state between the rectifier transformer 12 and the voltage regulating transformer 11, or to disconnect the electrical connection state between the load terminal 2 and the rectifier transformer 12.

[0044] As can be seen from the above embodiments, in the embodiments of the present utility model, since the transformer assembly 1 includes a voltage regulating transformer 11 and at least two rectifier transformers 12, each rectifier transformer 12 is electrically connected to the voltage regulating transformer 11, and there are at least two load terminals 2, each load terminal 2 is electrically connected to a rectifier transformer 12. Therefore, a voltage regulating transformer 11 can be used to control multiple rectifier transformers 12 simultaneously, and then the load terminals can be controlled through the rectifier transformers 12, so as to achieve the effect of a voltage regulating transformer 11 controlling multiple load terminals 2, which is conducive to reducing the manufacturing cost of the hydrogen production power supply control device. Also, since the power-off component 3 is electrically connected in the electrical connection line between each rectifier transformer 12 and the voltage regulating transformer 11, or the power-off component 3 is electrically connected in the electrical connection line between the load terminal 2 and the rectifier transformer 12, or the power-off component 3 is electrically connected in the electrical connection line between the load terminal 2 and the rectifier transformer 12 and the electrical connection line between each rectifier transformer 12 and the voltage regulating transformer 11. Herein, the power-off component 3 is used to disconnect the electrical connection state between the rectifier transformer 12 and the voltage regulating transformer 11, or to disconnect the electrical connection state between the load terminal 2 and the rectifier transformer 12. Therefore, when any load terminal 2 or any rectifier transformer 12 fails, it only needs to disconnect the electrical connection line between the corresponding rectifier transformer 12 and the voltage regulating transformer 11 through the power-off component 3, or disconnect the electrical connection line between the corresponding load terminal 2 and the rectifier transformer 12 through the power-off component 3, that is, only need to disconnect the electrical connection state between the faulty load terminal 2 and the corresponding rectifier transformer 12, or disconnect the electrical connection state between the faulty rectifier transformer 12 and the voltage regulating transformer 11, and the remaining load terminals 2 can operate normally.

[0045] In summary, in the hydrogen production power supply control device provided by the embodiments of the present utility model, even when any load terminal 2 or any rectifier transformer 12 fails for maintenance, the remaining load terminals 2 can continue to operate normally. Thus, while not affecting the maintenance of the faulty load terminal 2 or rectifier transformer 12, the overall hydrogen production efficiency can be improved, and power waste can be avoided.

[0046] Among them, the number of rectifier transformers 12 included in the transformer assembly 1 provided in the above embodiments can be any number such as two, three, four, etc., and the embodiments of the present utility model do not limit this. The number of load terminals 2 is the same as the number of rectifier transformers 12 included in the transformer assembly 1. Exemplarily, if the number of rectifier transformers 12 included in the transformer assembly 1 is two, then the number of load terminals 2 connected to each transformer assembly 1 is two; if the number of rectifier transformers 12 included in the transformer assembly 1 is three, then the number of load terminals 2 connected to each transformer assembly 1 is three.

[0047] It should be noted that the voltage regulating transformer 11 can be any one of types such as a single-phase transformer, a two-phase transformer, or a three-phase transformer. The voltage regulating transformer 11 usually uses the principle of electromagnetic induction to change the AC voltage. The voltage regulating transformer 11 can include a primary coil, a secondary coil, and an iron core. The voltage regulation of the voltage regulating transformer 11 is usually achieved by changing the coupling turns. On the toroidal iron core made of silicon steel sheets, the coil wound with high-strength enameled wire serves as both the primary coil and the secondary coil. By rotating the handwheel on the panel, the position of the sliding brush on the coil changes, thereby changing the coupling turns, and finally different output voltages are obtained between the terminals. The rectifier transformer 12 is mainly based on the principle of electromagnetic induction. The rectifier transformer 12 includes a primary winding and a secondary winding, and the primary winding and the secondary winding share an iron core. When the primary winding is connected to an AC power supply, an alternating current will flow through the winding and generate a magnetic potential, thereby forming an alternating magnetic flux in the iron core. The primary winding and the secondary winding will cut the magnetic force lines, and an alternating current with the same frequency is induced in the secondary. After passing through the rectifying elements, the output becomes a direct current. Through the rectifier transformer 12, an appropriate voltage can be given to the load terminal 2, and the pollution of the power grid caused by the waveform distortion caused by the transformer assembly 1 can be reduced, ensuring the normal transmission of the control signal.

[0048] The embodiment of the present utility model also provides a power-off component 3. The power-off component 3 can be arranged in the electrical connection line between each rectifier transformer 12 and the voltage regulating transformer 11, or can be arranged in the electrical connection line between the load terminal 2 and the rectifier transformer 12, or the power-off component 3 is arranged in both the electrical connection line between each rectifier transformer 12 and the voltage regulating transformer 11 and the electrical connection line between the load terminal 2 and the rectifier transformer 12. The specific type is determined according to the type of the power-off component 3 and the cost of the hydrogen production power supply control device. The embodiment of the present utility model does not make any limitation in this regard. It should be noted that without considering the cost of the hydrogen production power supply control device, the power-off component 3 can be arranged in both the electrical connection line between each rectifier transformer 12 and the voltage regulating transformer 11 and the electrical connection line between the load terminal 2 and the rectifier transformer 12. Thus, when any load terminal 2 or any rectifier transformer 12 fails, if the power-off component 3 in the electrical connection line between the rectifier transformer 12 and the voltage regulating transformer 11 cannot cut off the power, the power-off component 3 in the electrical connection line between the load terminal 2 and the rectifier transformer 12 can still be used to cut off the power, or when the power-off component 3 in the electrical connection line between the load terminal 2 and the rectifier transformer 12 cannot cut off the power, the power-off component 3 in the electrical connection line between the rectifier transformer 12 and the voltage regulating transformer 11 can still be used to cut off the power, so as to ensure the success rate of the power-off of the power-off component 3.

[0049] In some embodiments, the voltage regulating transformer 11 includes a voltage regulating transformer output terminal 111 and a high-voltage incoming line terminal 112, and the rectifier transformer 12 includes a rectifier transformer incoming line terminal 121 and a rectifier transformer output terminal 122; the voltage regulating transformer output terminal 111 is electrically connected to the rectifier transformer incoming line terminal 121, the rectifier transformer output terminal 122 is electrically connected to the load terminal 2, and the high-voltage incoming line terminal 112 is used to be electrically connected to a hydrogen production power source.

[0050] In this embodiment, the electrical connection between the voltage regulating transformer 11 and the rectifier transformer 12 is achieved through the electrical connection between the voltage regulating transformer output terminal 111 and the rectifier transformer incoming line terminal 121, and the electrical connection between the rectifier transformer 12 and the load terminal 2 is achieved through the electrical connection between the rectifier transformer output terminal 122 and the load terminal 2. In this way, it is convenient to set a disconnector between the voltage regulating transformer 11 and the rectifier transformer 12, and it is convenient to set a power-off component 3 between the rectifier transformer output terminal 122 and the load terminal 2.

[0051] In some embodiments, the power-off component 3 includes a high-voltage switch 31; the high-voltage switch 31 is electrically connected in the electrical connection line between the voltage regulating transformer output terminal 111 and the rectifier transformer incoming line terminal 121.

[0052] In this embodiment, the high-voltage switch 31 can be any one of the forms such as a manual knife switch, a remote control knife switch, a high-voltage switch cabinet, a high-voltage knife switch, etc., and the embodiments of the present invention do not limit this. When the high-voltage switch 31 is a manual knife switch, the manual knife switch can be any one of the types such as a pneumatic knife gate valve, an electric knife gate valve, a non-rising stem pneumatic knife gate valve, a wall-mounted knife switch, etc. Exemplarily, when the manual knife switch is a wall-mounted knife switch, the manual knife switch can be installed on any outer wall of the transformer assembly 1, thereby saving the space occupied by the high-voltage switch 31. When the high-voltage switch 31 is a remote control knife switch, through remote operation, the high-voltage switch 31 can be automatically opened and closed, which is more convenient to control the high-voltage switch 31, and at the same time, the safety and stability of the control can be improved.

[0053] In some embodiments, the transformer assembly 1 includes a housing 13, the rectifier transformer 12 and the voltage regulating transformer 11 are arranged inside the housing 13, the voltage regulating transformer output terminal 111, the high-voltage incoming line terminal 112, the rectifier transformer incoming line terminal 121 and the rectifier transformer output terminal 122 are all arranged on any outer surface of the housing 13, and the voltage regulating transformer 11 is led out of the housing 13 through the voltage regulating transformer output terminal 111 and electrically connected to the rectifier transformer incoming line terminal 121.

[0054] In this embodiment, the outer shell 13 is a housing structure for accommodating the rectifier transformer 12 and the voltage regulating transformer 11. The outer shell 13 can be a square housing, a cylindrical housing, or a housing structure of other shapes, and the embodiments of the present utility model do not limit this. Multiple partition structures can be formed inside the outer shell 13, thereby partitioning multiple relatively independent cavity regions, so that the rectifier transformer 12 and the rectifier transformer 12 can be respectively installed in independent cavity regions. In this way, while facilitating installation, mutual interference between the rectifier transformer 12 and the rectifier transformer 12 can be avoided. In addition, since the voltage regulating transformer output terminal 111, the high-voltage incoming line terminal 112, the rectifier transformer incoming line terminal 121, and the rectifier transformer output terminal 122 are all arranged on any outer surface of the outer shell 13, the voltage regulating transformer output terminal 111, the high-voltage incoming line terminal 112, the rectifier transformer incoming line terminal 121, and the rectifier transformer output terminal 122 are all arranged on the same surface of the outer shell 13. That is, the electrical connection cables between the rectifier transformer incoming line terminal 121 and the voltage regulating transformer output terminal 111, between the high-voltage incoming line terminal 112 and the hydrogen production power supply, and between the rectifier transformer output terminal 122 and the load terminal 2 can all be arranged on the same surface of the outer shell 13. In this way, while facilitating the maintenance and installation of the cables, it is beneficial to reduce the space occupied by the electrical connection between the connection terminals. In addition, when the rectifier transformer output terminal 122 is relatively complexly distributed, a cable combing assembly can be provided to guide the corresponding electrical connection cables to be electrically connected to the corresponding connection terminals, which can avoid the crossing and entanglement of the electrical connection cable routing, thereby reducing the failure rate and mis-touch rate of the electrical connection cables.

[0055] It should also be noted that in this embodiment, since the voltage regulating transformer 11 is led out to the outside of the outer shell 13 through the voltage regulating transformer output terminal 111 and is electrically connected to the rectifier transformer incoming line terminal 121, the electrical connection cable needs to be led out to the outside of the outer shell 13 through the voltage regulating transformer output terminal 111, electrically connected to the rectifier transformer incoming line terminal 121, and then introduced into the housing interior through the rectifier transformer incoming line terminal 121. Based on this, a wire harness seal and a guiding member can be provided in the voltage regulating transformer output terminal 111 and the rectifier transformer incoming line terminal 121, which can improve the sealing performance inside the transformer assembly 1 while facilitating the introduction or extraction of the electrical connection cable, and extend the service life of the transformer assembly 1.

[0056] In some embodiments, the power-off assembly 3 includes a circuit breaker 32; the circuit breaker 32 is electrically connected in the electrical connection line between the load terminal 2 and each rectifier transformer 12.

[0057] In this embodiment, the circuit breaker 32 is a switching device capable of closing, carrying, and interrupting the current under normal circuit conditions, and is also a switching device capable of closing, carrying, and interrupting the current under abnormal circuit conditions within a specified time. Thus, when the circuit breaker 32 is provided in the electrical connection line between the load terminal 2 and each rectifier transformer 12, in the event of a failure of any load terminal 2 or any rectifier transformer 12, the electrical connection line between the corresponding load terminal 2 and the rectifier transformer 12 can be disconnected through the circuit breaker 32, achieving the effect of separately disconnecting the corresponding load terminal 2.

[0058] In some embodiments, the transformer assembly 1 includes a housing 13; the rectifier transformer and the voltage regulating transformer are disposed inside the housing, the output terminal 111 of the voltage regulating transformer and the input terminal 121 of the rectifier transformer are disposed inside the housing 13, and the high-voltage input terminal 112 and the output terminal 122 of the rectifier transformer are disposed on any outer surface of the housing 13.

[0059] In this embodiment, the output terminal 111 of the voltage regulating transformer and the input terminal 121 of the rectifier transformer can be electrically connected inside the housing 13, that is, the voltage regulating transformer 11 and the rectifier transformer 12 are electrically connected inside the housing 13. In this way, only the high-voltage input terminal 112 and the output terminal 122 of the rectifier transformer are disposed on any outer surface of the housing 13, so that the electrical connection cables between the high-voltage input terminal 112 and the hydrogen production power supply and between the output terminal 122 of the rectifier transformer and the load terminal 2 are located outside the housing 13. Furthermore, the exterior of the transformer assembly 1 is made more concise, that is, the arrangement of the electrical connection cables outside the transformer assembly 1 can be reduced. While reducing costs, the crossing and entanglement of the electrical connection cables can be avoided, thereby reducing the failure rate and mis-touch rate of the electrical connection cables.

[0060] In some embodiments, both the voltage regulating transformer 11 and the rectifier transformer 12 are three-phase transformers.

[0061] In this embodiment, since both the voltage regulating transformer 11 and the rectifier transformer 12 are three-phase transformers, compared with the voltage regulating transformer 11 and the rectifier transformer 12 being two-phase transformers or single-phase transformers, the transformer assembly 1 can handle high power and current, improve the stability of the output voltage, and provide a more reliable power supply. Among them, since a three-phase transformer consists of three main windings and three secondary windings, and the angle between each winding is 120 degrees, it can handle greater power and current. In addition, the three power supplies of the three-phase transformer are balanced, that is, the voltage and current of each phase are equal. This balance helps to reduce problems such as current fluctuations and voltage instability, improving the stability and reliability of the system. At the same time, the phase difference of three-phase alternating current is 120 degrees, which can achieve a rotating magnetic field and is suitable for the starting and operation of high-power equipment, thus providing a more reliable power supply.

[0062] It should be noted that since both the voltage regulating transformer 11 and the rectifier transformer 12 are three-phase transformers, the voltage regulating transformer output terminal 111 and the high-voltage incoming line terminal 112 included in the voltage regulating transformer 11 are both three-port connection terminals, and the rectifier transformer incoming line terminal 121 and the rectifier transformer output terminal 122 included in the rectifier transformer 12 are both three-port connection terminals.

[0063] In some embodiments, a power-off component 3 is provided in the electrical connection line between the rectifier transformer 12 and the voltage regulating transformer 11 and in the electrical connection line between the load terminal 2 and the rectifier transformer 12; the transformer assembly 1 includes a housing 13, the rectifier transformer 12 and the voltage regulating transformer 11 are arranged inside the housing 13, and the voltage regulating transformer output terminal 111, the high-voltage incoming line terminal 112, the rectifier transformer incoming line terminal 121 and the rectifier transformer output terminal 122 are all arranged on any outer surface of the housing 13; the voltage regulating transformer 11 is led out to the outside of the housing 13 via the voltage regulating transformer output terminal and is electrically connected to the rectifier transformer incoming line terminal 121.

[0064] It should be noted that in this embodiment, since a power-off component 3 is provided in the electrical connection line between the rectifier transformer 12 and the voltage regulating transformer 11 and in the electrical connection line between the load terminal 2 and the rectifier transformer 12, when any load terminal 2 or any rectifier transformer 12 fails, if the power-off component 3 in the electrical connection line between the rectifier transformer 12 and the voltage regulating transformer 11 cannot cut off the power, the power can also be cut off through the power-off component 3 in the electrical connection line between the load terminal 2 and the rectifier transformer 12, or, when the power-off component 3 in the electrical connection line between the load terminal 2 and the rectifier transformer 12 cannot cut off the power, the power can also be cut off through the power-off component 3 in the electrical connection line between the rectifier transformer 12 and the voltage regulating transformer 11, so as to ensure the success rate of power-off of the power-off component 3.

[0065] In some embodiments, the hydrogen production power control device further includes a radiator 14; the radiator 14 is arranged on at least two side walls of the transformer assembly 1.

[0066] In this embodiment, the radiator 14 can be at least one of radiators 14 such as a liquid-cooled radiator 14, an air-cooled radiator 14 or a contact radiator 14. The embodiments of the present invention do not limit this. In this way, arranging the radiator 14 on at least two side walls of the transformer assembly 1 can ensure the safe and stable operation of the transformer assembly 1 in a high-temperature environment. It should be noted that as Figure 3 shown, at least two side walls of the transformer assembly 1 can be any two outer surfaces of the transformer assembly 1 that do not have connection ports, so as to avoid the influence of arranging the radiator 1 on the wiring of the rectifier transformer 12 and the voltage regulating transformer 11.

[0067] In some embodiments, the rectifier transformer 12 and the voltage regulating transformer 11 include a phase-shifting circuit for increasing the number of rectification pulses. The phase-shifting circuit is provided at least at one of the voltage regulating transformer output terminal 111, the rectifier transformer input terminal 121, and the rectifier transformer output terminal 122. The phase-shifting range of the phase-shifting circuit is between 0° and 360°.

[0068] In this embodiment, the phase-shifting circuit has a phase-shifting function, that is, a circuit that can change the waveform of alternating current without changing according to the original angle. Since the rectifier transformer 12 can include multiple secondary windings, the phases of the secondary windings differ by a preset angle. The preset angle is an angle set according to different application scenarios. In actual implementation, the preset angle can be 15°. Of course, according to different application requirements, it can also be an angle of other values. This embodiment does not limit this. In this way, when the rectifier transformer 12 and the voltage regulating transformer 11 include a phase-shifting circuit and the phase-shifting circuit is provided at least at one of the voltage regulating transformer output terminal 111, the rectifier transformer input terminal 121, and the rectifier transformer output terminal 122, the number of rectification pulses can be increased through the phase-shifting circuit, and the initial phase reaching the rectifier transformer 12 can be a preset phase with any value, thereby adapting to the load terminal 2 with different pulses and improving the adaptability of the transformer assembly 1.

[0069] In some embodiments, the load terminal 2 includes at least two rectifier cabinets 21 and at least two electrolytic cells 22; each rectifier cabinet 21 is electrically connected between an electrolytic cell 22 and a rectifier transformer 12.

[0070] In this embodiment, since each rectifier cabinet 21 is electrically connected between an electrolytic cell 22 and a rectifier transformer 12, when any electrolytic cell 22 fails, it is only necessary to disconnect the electrical connection state between the rectifier cabinet 21 corresponding to the failed electrolytic cell 22 and the rectifier transformer 12, or disconnect the electrical connection state between the rectifier transformer 12 corresponding to the failed electrolytic cell 22 and the voltage regulating transformer 11. The remaining electrolytic cells 22 can operate normally. In this way, the overall efficiency of hydrogen production can be improved, and it is also convenient to repair the failed electrolytic cell 22.

[0071] As can be seen from the above embodiments, in the embodiments of the present utility model, since the transformer assembly 1 includes a voltage regulating transformer 11 and at least two rectifier transformers 12, each rectifier transformer 12 is electrically connected to the voltage regulating transformer 11, and there are at least two load terminals 2, each load terminal 2 is electrically connected to a rectifier transformer 12. Therefore, a voltage regulating transformer 11 can be used to control multiple rectifier transformers 12 at the same time, and then the load terminals can be controlled through the rectifier transformers 12, so as to achieve the effect of a voltage regulating transformer 11 controlling multiple load terminals 2, which is beneficial to reducing the manufacturing cost of the hydrogen production power supply control device. Also, since the power-off assembly 3 is electrically connected in the electrical connection line between each rectifier transformer 12 and the voltage regulating transformer 11, or the power-off assembly 3 is electrically connected in the electrical connection line between the load terminal 2 and the rectifier transformer 12, or the power-off assembly 3 is electrically connected in the electrical connection line between the load terminal 2 and the rectifier transformer 12 and the electrical connection line between each rectifier transformer 12 and the voltage regulating transformer 11. Herein, the power-off assembly 3 is used to disconnect the electrical connection state between the rectifier transformer 12 and the voltage regulating transformer 11, or to disconnect the electrical connection state between the load terminal 2 and the rectifier transformer 12. Therefore, when any load terminal 2 or any rectifier transformer 12 fails, it is only necessary to disconnect the electrical connection line between the corresponding rectifier transformer 12 and the voltage regulating transformer 11 through the power-off assembly 3, or to disconnect the electrical connection line between the corresponding load terminal 2 and the rectifier transformer 12 through the power-off assembly 3, that is, it is only necessary to disconnect the electrical connection state between the faulty load terminal 2 and the corresponding rectifier transformer 12, or to disconnect the electrical connection state between the faulty rectifier transformer 12 and the voltage regulating transformer 11, and the remaining load terminals 2 can operate normally.

[0072] In summary, in the hydrogen production power supply control device provided by the embodiments of the present utility model, even when any load terminal 2 or any rectifier transformer 12 fails and needs to be repaired, the remaining load terminals 2 can continue to operate normally. Therefore, while not affecting the repair of the faulty load terminal 2 or rectifier transformer 12, the overall efficiency of hydrogen production can be improved, and power waste can be avoided.
