Detailed implementation manners

[0019] As Figures 1 to 6 shown, a detection and display device for an industrial and commercial energy storage system is characterized in that: a fixing flange 102 is arranged on the outer side of the base body 101, and the base body 101 is detachably connected to the energy storage cabinet through the fixing flange 102. A panel body 201 is arranged inside the base body 101, and the base body 101 is detachably connected to the upper cover body 301.

[0020] The surface of the base body 101 is longitudinally provided with an indication lamp 103 of no entry for gas release, an operation status indication lamp 104 and an emergency stop button fixing hole 105. O-ring seals 401 are respectively arranged in the indication lamp 103 of no entry for gas release, the operation status indication lamp 104 and the emergency stop button fixing hole 105 for sealing. The font of no entry for gas release is silk-screened on the indication lamp 103 of no entry for gas release, and the fonts of operation, fault and alarm are silk-screened on the operation status indication lamp 104. The emergency stop button 501 is connected to the emergency stop button fixing hole 105 through threads. A wiring pin is arranged at the bottom of the emergency stop button 501, and the wiring pin is electrically connected to the panel body 201 through a wire harness. The emergency stop button 501 is used to make the system enter a power-off and shutdown state. A plurality of control board fixing posts 107 are symmetrically arranged inside the base body 101, and a wire outlet hole 108 is arranged at the bottom of the base body 101.

[0021] The panel main body 201 is detachably connected to the control board fixing post 107. An upper lamp bead array 202 and a lower lamp bead array 203 are respectively arranged on the panel main body 201. The position of the upper lamp bead array 202 corresponds to that of the do not enter when deflating indicator lamp 103, and the position of the lower lamp bead array 203 corresponds to that of the operation status indicator lamp 104. A combustible gas composite detection unit is arranged on the panel main body 201. The combustible gas composite detection unit detects the temperature and flammable and explosive gases in the energy storage cabinet through the air permeable hole 302 of the upper cover main body 301. The panel main body 201 receives the detection signal of the combustible gas composite detection unit and controls the opening and closing of the upper lamp bead array 202 and the lower lamp bead array 203 to display the operation status. The communication line and power line of the panel main body 201 are connected to the energy storage system energy management unit EMS through the wire outlet hole 108.

[0022] The upper cover main body 301 is provided with upper cover fixing holes 303. The positions of the upper cover fixing holes 303 correspond to those of the base fixing holes 106 of the base main body 101 for the detachable connection of the upper cover main body 301 and the base main body 101. The air permeable hole 302 is arranged on the upper cover main body 301.

[0023] In the embodiment, when the energy storage cabinet operates normally, the energy storage system energy management unit EMS sends a signal of normal system operation to the panel main body 201.

[0024] When the energy storage cabinet fails, the energy storage system energy management unit EMS sends a signal of system failure to the panel main body 201, so that the failure indicator lamp on the operation status indicator lamp 104 lights up, thereby indicating that the energy storage cabinet fails, and at the same time, the operation indicator lamp goes out.

[0025] When there is a potential safety risk in the energy storage cabinet, the energy storage system energy management unit EMS sends a signal of potential safety risk in the system to the panel main body 201, so that the warning indicator lamp on the operation status indicator lamp 104 lights up, thereby indicating that there is a potential safety risk in the energy storage cabinet, and at the same time, the operation and failure indicator lamps go out.

[0026] When the combustible gas composite detection unit detects flammable and explosive gases generated in the energy storage cabinet, after the panel main body 201 receives the detection signal, it lights up the upper lamp bead array 202, making the do not enter when deflating indicator lamp 103 light up, and the fire protection system in the energy storage cabinet starts.

[0027] Regardless of whether the energy storage cabinet is in the state of operation, fault, or alarm, simply pressing the emergency stop button 501 will disconnect the main circuit breaker inside the energy storage cabinet, and the energy storage cabinet will enter the power-off and shutdown state. Only by manually closing the main circuit breaker can the energy storage cabinet restart and operate again.

[0028] The above description is illustrative rather than restrictive to the present utility model. Those of ordinary skill in the art understand that without departing from the spirit and scope defined by the claims, many modifications, variations, or equivalents can be made, but all will fall within the protection scope of the present utility model.
