The conventional hydrogen production process requires the use of direct current, so the hydrogen production power supply usually needs to include an AC / DC conversion circuit, which needs to rectify the AC into DC. The hydrogen production power supply consists of a transformer, a rectifier and a low-voltage hydrogen distribution cabinet. The transformer reduces the three-phase AC input from the grid side to a rated low-voltage AC; the rectifier converts the low-voltage AC into DC through a rectifier circuit; the DC output of the rectifier is connected to the hydrogen production electrolyzer to provide power for the electrolyzer.

[0003] The transformer box is a box in the hydrogen production power system where the voltage and current of electric energy are transformed, concentrated and distributed. In order to ensure the quality of electric energy and the safety of equipment, voltage adjustment, flow (the flow and distribution of voltage, current and power in each node and branch of the power system) control and protection of transmission and distribution lines and major electrical equipment are also required in the transformer box. It is mainly used to protect power facilities. However, in the prior art of alkali liquid hydrogen production, the transformer box can generally only exchange temperature through natural wind convection and then cool down, and cannot cool down autonomously. In addition, the power is relatively high during the hydrogen production process, and there is a common problem: most transformer boxes will experience unexpected power outages due to high temperatures, which will lead to the failure of continuous production of hydrogen in the alkali liquid electrolysis cell and even crystallization problems.

[0017] 1. The KOH intelligent long-time power supply device is provided with a cooling transformer assembly. The transformer for hydrogen production by electrolysis and the rectifier circuit components can be installed in an independent cabinet and can be fixed in parallel on the component mounting plate. When the electrolyzer is running, only one of the cooling transformer assemblies is running. At this time, the cooling water will fill the inside of the two cooling frames from above, and the cooling water will flow through the cooling frames from top to bottom and be discharged from the drainer.

When the equipment runs continuously and a high-temperature fault occurs, another cooling substation component can be switched at any time. When the water circuit switching is difficult to operate, the manual operating handle can be manually pulled to supply most of the cooling water to the running cooling substation component, and at the same time pre-cool another cooling substation component for switching at any time.

[0020] 4. The KOH intelligent long-time power supply device has an outer box body, in which the circuit components of the device are installed, and the main heat-generating rectifiers are installed in independent cabinets, so the temperature inside the outer box rises slowly.

[0041] A single independent cabinet 401 is fixed to the outer box 1 by bolts and feet, and the cooling frame 402 is fixed at the inner center of the independent cabinet 401. The connecting beam 407 and the bottom beam 403 are hollowed out, which can increase the structural strength while reducing the overall weight of the independent cabinet 401. There is space between the two cooling frames 402 to facilitate exhaust and avoid excessive heating.

[0042] The two cooling frames 402 are arranged in opposite directions, and a plurality of ridges 411 are provided on the sides away from each other. The ridges 411 are arranged equidistantly up and down, and equidistant bars 412 are fixed at the grooves corresponding to the ridges 411 in the cooling frame 402. Both ends of the equidistant bars 412 are fixed to the inner wall of the cooling frame 402. There is a flow channel 413 between the equidistant bars 412 and the inner wall of the ridges 411. Both the head and the tail of the flow channel 413 are connected to the chamber 406, and a component mounting plate 414 is fixedly installed at the convex part of the outer surface of the ridge 411.

[0043] The cooling frames 402 are arranged back to back with reserved space, the ridges 411 can be customized according to the actual number of components, and the components can be installed in parallel. The cooling frames 402 and the ridges 411 are made by integrated stamping, which can not only realize the natural flow of internal cooling water, but also transfer heat as a whole.

[0044] The cooling and substation assembly 4 also includes a cabinet door 415. Both ends of the independent cabinet 401 are provided with openings 416. The convex strips 411 and the component mounting plate 414 correspond to the openings 416. The cabinet door 415 is installed on the independent cabinet 401 to close the openings 416. It also includes a plurality of fans 417, which are installed together on one side of the independent cabinet 401. A breathable net 418 is installed on the corresponding side of the independent cabinet 401. The breathable net 418 corresponds to the number and position of the fans 417.

[0045] Three cooling and transformer subassemblies 4 are installed in parallel in the outer box body 1, and maintenance space is reserved between any two of them for maintenance personnel, and no interference occurs when the cabinet door 415 is opened, ensuring that the cabinet door 415 can be fully opened during maintenance. Multiple fans 417 can be set, and the fan 417 is set opposite to the breathable net 418 to assist in heat dissipation.

[0046] The water distribution component 2 includes a water distributor 201, a main water inlet pipe 202, a motor 203 and an output pipe 204. The water distributor 201 and the motor 203 are both fixed to the inner top wall of the outer box body 1. The output end of the motor 203 is fixedly installed with a rotating shaft 205, and the rotating shaft 205 is connected to the water distributor 201, and is used to drive the water distributor 201 to input cooling water into two of the cooling and transformer components 4. The output end of the water distributor 201 is provided with three connectors 206, and the output pipe 204 is provided with three, one end of which is connected to the connector 206, and the other end is connected to the water inlet 404; one end of the main water inlet pipe 202 is outside the outer box body 1, and the other end is connected to the water distributor 201.

[0047] The main water inlet pipe 202 is connected to the electrolysis water circuit. A reducer is provided inside the motor 203 . The motor 203 is controlled by a servo driver to ensure the operating angle of the water distributor 201 .

[0048] The water distributor 201 includes a conical water distributor 2011, a sealed water distributor plate 2012 and a sealed bottom shell 2013. The conical water distributor 2011 is fixed on the sealed bottom shell 2013 to form a cavity structure. The sealed water distributor plate 2012 is located in the sealed bottom shell 2013, and its diameter matches the inner diameter of the sealed bottom shell 2013. The sealed water distributor plate 2012 is rotatably connected to the sealed bottom shell 2013. The rotating shaft 205 is fixedly connected to the main shaft of the sealed water distributor plate 2012. A manual operating handle 201 is fixedly installed on one end of the rotating shaft 205 outside the sealed water distributor plate 2012. 4. The bottom surface of the sealed bottom shell 2013 is provided with three drain holes 2015 which penetrate up and down, and the three drain holes 2015 correspond to the three connectors 206 respectively. The sealed water separation plate 2012 is provided with large holes 2016 and small holes 2017 which penetrate up and down respectively, and the large holes 2016 and the small holes 2017 correspond to two of the drain holes 2015 respectively. The inner cavity of the conical water separation cover 2011 corresponds to the large holes 2016 and the small holes 2017. The rotating shaft 205 penetrates the center of the conical water separation cover 2011. The main water inlet pipe 202 is fixed to the conical water separation cover 2011 and the two are connected to each other.

[0049] When the manual operating handle 2014 is in use, the coupling between the rotating shaft 205 and the main shaft of the motor 203 needs to be disconnected, so as to manually control the rotation position of the sealed water separation plate 2012. The upper end of the conical water separation cover 2011 is a trumpet-shaped structure, which can connect the incoming water to the large hole 2016 and the small hole 2017 respectively.

[0050] The drainage assembly 3 includes a drainage pipe 301 , which is connected to three drains 405 , and one end of the drainage pipe 301 passes through the outer box 1 .

[0051] The drain pipe 301 can be connected to the electrolytic circulation water circuit after passing through the outer box 1 to supply the electrolytic cell.

[0052] Two protectors 5 are fixed to the inner bottom wall of the outer box body 1 , respectively located between two adjacent independent cabinets 401 , and the drain pipe 301 passes through the lower end of the protector 5 .

[0053] The protector 5 is used to prevent maintenance personnel from stepping on the drain pipe 301 during maintenance, thereby protecting the maintenance personnel from tripping.

[0054] An inspection door 6 is installed on the outer box body 1.

[0055] A plurality of exhaust fans 7 are provided at the upper end of the outer box body 1 .

[0056] When in use, the transformer and rectifier circuit components of the electrolytic hydrogen production can be installed in an independent cabinet 401 and can be fixed in parallel on the component mounting plate 414. When the electrolyzer is running, only one of the cooling transformer components 4 is powered on at high power, and the remaining two cooling transformer components 4 are powered on at low power as standby. At this time, the cooling water will fill the inside of the two cooling frames 402 from the top through the cooling water tank and the water pump. The cooling water will flow through the cooling frames 402 from top to bottom and be discharged from the drainer 405. The cooling water flow rate can be adjusted according to the rectifier, transformer, and other components. The load size of the device is adjusted. The cooling water after being heated will be squeezed to the bottom of the cooling frame 402. The cooling water inside the cooling frame 402 will pass through the flow channel 413 between the equidistant strips 412 and the convex strips 411. The cooling water will mix inside it during this process, thereby cooling the convex strips 411. The heat generated by the electronic components will be transferred to the convex strips 411 and then taken away by the cooling water, ensuring that the electronic components always operate in an environment not exceeding 45°C. The fan 417 on the independent cabinet 401 is used to further exhaust the hot gas inside the independent cabinet 401.

[0057] When the electrolysis operation is in progress, one of the cooling transformer components 4 is in operation. At this time, the large hole 2016 on the sealed water distribution plate 2012 corresponds to the output pipe 204 connected to the cooling frame 402 in the cooling transformer component 4, and the other small hole 2017 corresponds to the output pipe 204 of another cooling transformer component 4. Therefore, the running components can be cooled at full flow rate, and the last cooling transformer component 4 that has completed operation can be pre-cooled at a low flow rate.

[0058] Since most of the energy for hydrogen production by alkaline solution electrolysis comes from wind and solar power, there is a large volatility in energy. When the equipment is running continuously and a high-temperature fault occurs, another cooling substation assembly 4 can be switched at any time. When the water switch is difficult to operate due to a power outage, the manual operating handle 2014 can be manually pulled to supply most of the cooling water to the running cooling substation assembly 4, and at the same time, another cooling substation assembly 4 can be pre-cooled for switching at any time. During peak operation, the operating interval of each cooling substation assembly 4 can be dynamically adjusted according to the operating time to achieve three-way non-stop exchange to ensure uninterrupted hydrogen production.

[0059] The circuit components of the device are all installed in the outer box body 1, and the main heat-generating rectifier parts are installed in the independent cabinet 401, so the temperature inside the outer box body 1 rises slowly. An exhaust fan 7 is provided to discharge the internal hot air upward in time. An inspection door 6 is provided so that maintenance personnel can enter for maintenance at any time. The entire outer box body 1 is integrated and can be moved to any position by hoisting equipment, and can also be changed at will.

[0060] After running inside the cooling frame 402, the cooling water is used to replenish the electrolytic cell, thus completing a water circuit.
