[0035] In combination with Figure 4 and Figure 6As shown, the box 112 is externally provided with a pair of plug-in terminals for connecting the primary cable incoming line 240 to the PCS 120, the secondary equipment 130, the heat dissipation fan 140, the temperature and humidity controller 150, the liquid cooling system 160, the EMS 170, the human-computer interaction interface 180, the fire-fighting system 190, the communication module 200, the lighting system 210, the battery system 220, the UPS 230, and the dehumidifier 250.

[0036] The primary circuit electrical components are packaged in the box 112, and the connections between the lines are realized outside the box 112 by using the plug-in terminals, so that the entire power distribution cabinet can be externally and individually connected, without the need for complex internal connection and assembly, thereby reducing the assembly difficulty.

[0037] As shown in Figure 4 The fire-fighting system 190 includes a fire-fighting host 191, a warm smoke sensor 192, an aerosol 193, and four heat dissipation fans 194, which are respectively fixed on the sheet metal accessory 115 by bolts.

When the warm smoke sensor 192 senses that the temperature in the box 112 is too high, the fire-fighting host 191 can drive the heat dissipation fan 194 to dissipate heat from the box 112 to prevent the temperature in the box 112 from being too high. When the warm smoke sensor 192 detects that the temperature in the box 112 is too high and smoke appears at the same time, the aerosol 193 is used. The aerosol 193 is cracked, so that the aerosol particles come into contact with the flame, quickly absorb the heat in the flame, thereby reducing the temperature of the combustion area. Secondly, the aerosol particles and the free radicals in the flame react chemically, block the chain reaction of the flame, and make the flame unable to continue to burn. In addition, the high specific surface area and low ignition point of the aerosol particles can effectively limit the oxygen supply of the combustion area, further inhibiting the development of the fire.

[0041] As shown in the figure, Figure 5 The heat dissipation fan 140 is arranged on the sheet metal accessory 115 of the electrical cabinet door 114 close to the rear end of the box 112, and a dustproof filter screen 141 is arranged between the heat dissipation fan 140 and the PCS 120.

[0042] Among them, the dustproof filter screen 141 is arranged between the heat dissipation fan 140 and the PCS 120, since the energy storage cabinet is used outdoors, by adding a layer of dustproof filter screen between the PCS and the fan, the situation that dust enters the box 112 is reduced, and the setting of the dustproof filter screen also plays an electrical isolation role, so that the worker will not directly contact the high-voltage during maintenance, and the safety of the worker is improved when the dustproof effect of the electrical cabin is improved.

[0043] As shown in the figure, Figure 7 The frame 116 is composed of square tubes welded into a cage type steel skeleton.

[0044] Among them, the frame 116 is welded by square tubes, and the frame 116 is assembled into a cage type steel skeleton, which can effectively resist impact in all directions, enhance the firmness and reliability of the entire cabinet during transportation, and reduce the risk of frame damage caused by impact on the cabinet.
