A two-position valve switches between high (21 MPa) and low (5 MPa) pressure, improving the efficiency of the hydraulic pump station 4. The chiller 6 provides cooling water for the system. On the one hand, it provides cooling water for the welding head to limit the temperature rise of the welding machine; on the other hand, it provides cooling for the return oil of the hydraulic pump station 4 to ensure that the temperature of the hydraulic oil is controlled within a certain range.

[0044] In this embodiment, Figure 3 and Figure 4The diagram shows the second container from various angles. The overall layout of the second container is divided into two compartments: a battery compartment and an electrical compartment. Fireproof insulation panels are used to physically separate the two compartments to prevent a fire in the battery compartment from spreading to the electrical compartment and damaging other equipment. The battery compartment primarily houses lithium iron phosphate batteries 13, supercapacitors 11, cooling air conditioners, and fire protection systems. The fire protection system monitors each battery pack for abnormalities. In the event of high temperatures or smoke, it immediately cuts off power and initiates firefighting measures, effectively preventing further malfunctions. The electrical compartment primarily houses a bidirectional DC / DC converter 14, a high-power bidirectional 3AC / DC converter 17, a transformer 16, and a second power distribution cabinet 15.

[0045] In this embodiment, the shutters 9 are conducive to cooling the equipment and ensuring the working stability of the electrical equipment.
