[0041] In the utility model embodiment, external AC power is input into the rectifier power mechanism 2 through the first AC input row 11, is changed into DC power after rectification of the rectifier power mechanism 2, and the DC power is transmitted to hydrogen production equipment through the first DC output row 12 after passing through the disconnecting switch 4, while starting the cooling mechanism 3, and the cooling water is input into the cooling mechanism 3 from the inlet and outlet water port 13 through the water pump, and then is transmitted to the rectifier power mechanism 2, to cool the rectifier power mechanism 2, to complete rectification and heat dissipation of the rectifier power supply device.

[0042] The current hydrogen production method is electrolytic hydrogen production, which needs to use a rectifier power supply. The rectifier power supply is usually set in a scattered and independent cabinet, which needs complex on-site construction during installation, thereby causing low installation efficiency and long time consumption. When the installation site needs to be changed, the rectifier power supply device needs to be disassembled and moved. Since the rectifier power supply is large in size and scattered in structure, the rectifier power supply is difficult to disassemble and transport, and is inconvenient to reuse. In addition, the electrolytic hydrogen production system is usually installed in a harsh environment, thereby causing the rectifier power supply device to be easily affected by the external environment and causing faults, thereby affecting the stable operation of the electrolytic hydrogen production system. In the embodiment of the utility model, the rectifier power supply mechanism 2, the cooling mechanism 3 and the disconnecting switch 4 are all arranged in the container 1, so that a complete and independent power supply system is formed. Therefore, during installation at the construction site, complex assembly is not needed.

[0044] Further, the rectifier power supply mechanism 2 is provided with a second AC input row and a second DC output row. The second AC input row is connected with the first AC input row 11.

The first water inlet and outlet pipe 21 is suitable for introducing cooling water to dissipate the heat generated by the rectifier power supply mechanism 2. The cooling water in the cooling mechanism 3 enters the rectifier power supply mechanism 2 through the first water inlet and outlet pipe 21 to cool the rectifier power supply mechanism 2.

[0046] Further, the cooling mechanism 3 is provided with a second water inlet and outlet pipe 31 and a third water inlet and outlet pipe 32, the second water inlet and outlet pipe 31 is connected with the water inlet and outlet 13, and the third water inlet and outlet pipe 32 is connected with the first water inlet and outlet pipe 21. The cooling water enters from the water inlet and outlet 13, enters the cooling mechanism 3 through the second water inlet and outlet pipe 31, and then enters the radiator in the rectifier power supply mechanism 2 through the third water inlet and outlet pipe 32. The cooling water absorbs heat in the radiator and then returns to the cooling mechanism 3 for cooling, and then returns to the radiator in the rectifier power supply mechanism 2, which circulates repeatedly to dissipate heat for the rectifier power supply mechanism 2.

[0047] Further, the container 1 is provided with a support frame 7 below the disconnecting switch 4, and the disconnecting switch 4 is installed on the support frame 7. By providing the disconnecting switch 4, the on-off control of the circuit can be realized, thereby protecting the rectifier power supply device, and at the same time ensuring sufficient insulation distance and breaking point in the breaking state, thereby ensuring the safe isolation of the circuit.

[0048] Further, as shown in Figure 2 , the top of the container 1 is provided with a top light 14, which is suitable for illuminating the inside of the container 1. When the equipment inside the container 1 needs to be maintained, the top light 14 can provide convenient lighting.

[0049] Further, the back of the container 1 is provided with an axial flow fan 15 near the disconnecting switch 4, which is suitable for ventilating the inside of the container 1. By providing the axial flow fan 15, the inside of the container 1 can be ventilated to ensure the circulation of air flow in the container 1.

[0050] Further, as shown in Figure 4 , the back of the container 1 is provided with an outdoor air conditioner 16 near the cooling mechanism 3, which is suitable for dissipating heat in the inside of the container 1. By providing the outdoor air conditioner 16, the temperature in the inside of the container 1 can be adjusted, which is not affected by the external environment temperature, thereby avoiding the influence of the overheating of the equipment in the container 1 on the normal operation.

[0051] Further, as shown in Figure 3 and Figure 5 , the front of the container 1 is provided with a double-door 17, which is suitable for the installation of equipment, and the left side wall of the container 1 is provided with a single-door 18, which is suitable for the entry and exit of workers.

[0053] In the embodiment of the utility model, by setting the rectifier power mechanism 2, the cooling mechanism 3 and the disconnecting switch 4 in the container 1, the dust outside can be prevented from entering the container 1, thereby reducing the risk of equipment failure in the container 1, and ensuring the stable operation of the rectifier power device. In addition, by integrating various devices into the container 1, the power supply system of the hydrogen production equipment can occupy less space, saving the installation space of the rectifier power device, and being suitable for hydrogen production projects with limited space. When it is necessary to change the location of the hydrogen production device, whether it is a small hydrogen production station in the city or a large hydrogen production station in a remote area, the container 1 can be quickly delivered.

[0054] The specific working process of the container type rectifier power device for electrolytic hydrogen production provided by the utility model is as follows:

[0055] First, the external alternating current is input into the rectifier power mechanism 2 through the first alternating current input row 11 and the second alternating current input row, and is converted into direct current through the rectification of the rectifier power mechanism 2. The direct current is transmitted to the direct current sensor 6 through the second direct current output row, and then is transmitted to the disconnecting switch 4. The direct current is output from the first direct current output row 12 and enters the hydrogen production device, electrolyzes water to produce hydrogen. In the hydrogen production process, the cooling water enters the cooling mechanism 3 through the water inlet and outlet 13 and the second water inlet and outlet pipe 31, and then enters the rectifier power mechanism 2 through the third water inlet and outlet pipe 32 and the first water inlet and outlet pipe 21, so as to cool and dissipate heat of the rectifier power mechanism 2, thereby completing the rectification and heat dissipation of the rectifier power device.

[0056] Obviously, the above embodiments are only examples for clearly illustrating, and not limit the implementation. For ordinary skilled in the art, on the basis of the above description, other different forms of changes or variations can be made. Here, all the implementation ways need not and cannot be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the utility model.
