Description

Technical Field

[0001] The utility model belongs to the technical field of outdoor cabinet energy storage equipment, in particular to an outdoor string type integrated energy storage cabinet. Background Art

[0002] With the rapid development of renewable energy, the overall capacity of energy storage systems is also growing. The most popular way to increase capacity in the market is the string solution. This requires an integrated device with reliable system operation and reasonable structure to achieve a large-capacity market. At present, there are many string energy storage cabinet solutions on the market, each with its own advantages and disadvantages.

[0003] An outdoor cabinet energy storage system with publication number CN114759471A includes at least one cabinet, which has a cavity inside and a cabinet door outside; the energy storage module unit is installed on one side of the cabinet; the high-voltage box is installed on the top of the other side of the cabinet; the PCS cabinet is installed in the middle of the other side of the cabinet and installed at the bottom of the high-voltage box, which is close to the energy storage module unit; the DCDC module is installed in the middle of the other side of the cabinet and installed at the bottom of the high-voltage box, which is far away from the energy storage module unit; the ATS module is installed in the middle of the other side of the cabinet and installed at the bottom of the PCS cabinet; the switch control circuit unit is installed at the bottom of the other side of the cabinet; the air conditioner is installed at the top of the cabinet and its air outlet is suitable for connecting the energy storage module unit; the cabinet door is also provided with a PCS air inlet and a PCS air exchange outlet. The system has high integration, the air conditioner is integrated at the top of the cabinet, the appearance is beautiful, and the heat dissipation power consumption is small.

[0004] In the existing outdoor cabinet energy storage system, the air conditioner is placed on the top of the cabinet. This solution is beautiful, but the heat dissipation effect of the bottom of the cabinet is relatively poor, and the heat dissipation of the components in the cabinet is uneven, which leads to the aging of some components. This solution lacks a fire protection system in the cabinet. When the battery cluster catches fire, the cabinet itself has no fire extinguishing ability. The fire itself will affect other equipment, which is a great hidden danger to the safety of the entire energy storage system. Now more and more attention is paid to the safety of industrial production, which requires a reliable fire protection system to monitor and extinguish the battery cluster. Summary of the invention
