Hot air circulates through the air outlet filter 23 and the air inlet filter 32. The temperature detector 4 monitors the temperature inside the cabinet in real time and feeds back to the control system to adjust the air conditioner power. PACK5 is connected to the bidirectional inverter 10 through the battery high-voltage box 8 to realize the storage and release of electrical energy.

[0025] Example 2

[0026] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a battery high-voltage box 8 is fixedly connected inside the energy storage dedicated power distribution cabinet 18; an access control switch 9 is provided on the front of the energy storage dedicated power distribution cabinet 18; a bidirectional inverter 10 is fixedly connected to the inner wall of the control cavity of the energy storage dedicated power distribution cabinet 18; an emergency stop switch 11 is fixedly connected to one side of the control cabinet door 29; a running indicator light 12 is provided on one side of the emergency stop switch 11; an alarm indicator light 13 is provided on one side of the running indicator light 12; a fault indicator light 14 is provided on one side of the alarm indicator light 13; and an EMS controller 15 is provided below the emergency stop switch 11. Below the EMS controller 15 is a UPS 16, and below the UPS 16 is a fire controller 17. The lower end of the control cavity of the energy storage special distribution cabinet 18 is equipped with a grid connection terminal 19. The bottom of the control cavity of the energy storage special distribution cabinet 18 is equipped with a water immersion switch 21. The front of the energy storage special distribution cabinet 18 is equipped with a door opening and positioning mechanism 20.

EMS controller 15 monitors the charging and discharging status throughout the process, and operation indicator 12 displays the normal operating status in real time. The safety protection system works simultaneously: smoke detector 3 continuously monitors smoke, and water immersion switch 21 detects humidity inside the cabinet.

[0028] Example 3

[0029] like Figure 1-4As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a fire sprinkler mechanism 26 is provided on the inner wall of the control cavity of the energy storage special power distribution cabinet 18, a fire gas cylinder 27 is provided at the bottom of the inner cavity of the control cavity of the energy storage special power distribution cabinet 18, an EMS protective cover 30 is provided at the upper end of the front of the control cabinet door 29, a metal door lock 31 is provided on the front of the energy storage special power distribution cabinet 18, an air inlet filter 32 is provided at the lower end of the front of the control cabinet door 29, a control compartment rear door 33 is provided on one side of the back of the energy storage special power distribution cabinet 18, a battery compartment rear cover 34 is provided on the other side of the back of the energy storage special power distribution cabinet 18, and a fire water inlet 35 is provided on the surface of the battery compartment rear cover 34.

The inlet air filter 32 and outlet air filter 23 can be periodically disassembled and cleaned to ensure efficient heat dissipation.

[0031] The working principle of this air-cooled energy storage outdoor cabinet will be explained in detail below.

[0032] like Figure 1-4As shown, before system startup, the electrical cabinet door 28 and control cabinet door 29 are closed by metal door lock 31. After the access control switch 9 and door opening positioning mechanism 20 detect that the cabinet door is closed and locked, the system is allowed to start. If the cabinet door is not closed tightly, the alarm indicator light 13 will light up to indicate this. During operation, the air conditioner 1 starts, and cold air enters the air conditioner cold air duct 6 through the air conditioner cold air outlet duct 2, and flows evenly to the inside of the energy storage special distribution cabinet 18 to cool components such as PACK 5 and battery high voltage box 8. Hot air circulates through the air outlet filter 23 and the air inlet filter 32. The temperature detector 4 monitors the temperature inside the cabinet in real time and feeds it back to the control system to adjust the air conditioner power. PACK5 is connected to the bidirectional inverter 10 via the battery high-voltage box 8 to achieve energy storage and release: during charging, grid power is input through the grid connection terminal 19 and converted into DC power by the bidirectional inverter 10 and stored in PACK5; during discharging, the DC power released by PACK5 is converted into AC power by the bidirectional inverter 10 and transmitted to the grid through the grid connection terminal 19. The EMS controller 15 monitors the charging and discharging status throughout the process, and the operation indicator 12 displays the normal operating status in real time. The safety protection system works synchronously: the smoke detector 3 continuously monitors smoke, and the water immersion switch 21 detects the humidity inside the cabinet. If a fire or water leakage is detected, the fire controller 17 immediately activates the fire protection system, the fire extinguishing gas cylinder 27 releases the extinguishing medium, which is diffused into the cabinet through the fire pipe 24, fire sprinkler heads 25, and fire spraying mechanism 26. At the same time, the alarm indicator 13 flashes, the fault indicator 14 lights up, and the EMS controller 15 cuts off the main circuit. In an emergency, pressing the emergency stop switch 11 on the control cabinet door 29 can force a shutdown; the UPS 16 ensures that the control system continues to work during power outages. During maintenance, the electrical cabinet door 28 can be opened, and internal components can be easily removed via the guide rail mechanism 22. The control compartment rear door 33 and the battery compartment rear cover 34 are easy to inspect. In the event of an explosion, the fire water inlet 35 can inject water into the cabinet to extinguish the fire. The air inlet filter 32 and the air outlet filter 23 can be disassembled and cleaned regularly to ensure heat dissipation efficiency.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
