[0049] Wherein, the front of the cabinet 112 is provided with an electrical cabinet door 113, and the back is provided with a rear maintenance door 114. When performing early installation and later maintenance, the cabinet door that is more convenient to install or maintain is selected according to the actual situation, avoiding a large amount of disassembly and repair work on one cabinet door, greatly reducing the risk of damage to the energy storage cabinet door. By setting the liquid cooling device 180 at the bottom end of the inner cavity of the cabinet, due to the high protection level of the liquid cooling device 180, the electrical part in the energy storage cabinet can be raised, so that the electrical part and the battery system are not threatened by rain in the case of bottom immersion in bad weather, preventing the energy storage box from being scrapped due to immersion, ensuring its service life. The fire extinguishing system 230 includes a fire extinguishing host 231, a temperature sensor 232, a smoke sensor 233, an aerosol 234, a perfluorohexanone 235, and an explosion-proof valve 236.

The box 112 can be externally connected separately, and the external terminal box is connected between the box 112 by using a quick plug terminal. The modular design improves the space utilization rate in the box 112. The liquid cooling device 180 is arranged at the bottom end of the box cavity. Due to the high protection grade of the liquid cooling device 180, the electrical part in the energy storage cabinet can be raised. In the case of immersion of the bottom of the energy storage cabinet in bad weather, the electrical part and the battery system are not threatened by rainwater, preventing the energy storage cabinet from being scrapped due to immersion, and ensuring the service life. When the temperature sensor 232 detects that the temperature in the box 112 is too high, and the smoke sensor 233 detects that smoke appears in the box 112, the information is transmitted to the fire host 231. Then, the aerosol contacts the flame, quickly absorbs the heat in the flame, thereby reducing the temperature of the combustion area. At the same time, the aerosol 234 and the free radicals in the flame undergo a chemical reaction, blocking the chain reaction of the flame, so that the flame cannot continue to burn. The perfluorohexone 235 is easy to vaporize, has obvious cooling effect, and does not remain on the site after vaporization, which will not cause secondary damage to the equipment and cleaning difficulty. The aerosol 234 and the perfluorohexone 235 can quickly achieve the effect of extinguishing the fire without damaging the equipment. The explosion-proof valve 236 is fixedly installed on the back part of the energy storage cabinet cabinet 110, and the position and height thereof can effectively ensure the personal safety of the workers, and ensure the safety of the workers during maintenance.
