[0037] Example

[0038] In this embodiment, a 200kWh industrial and commercial energy storage integrated machine is used as an example for modification, and the newly added UPS5 adopts the model UPS-N-1K with a power of 1KV / 0.9KW.

[0039] Inside the distribution box, the molded case circuit breaker 2, the miniature circuit breaker 3, the relay 4, the traditional tower UPS device, the copper bus 15, the cables and other auxiliary materials are assembled together with the UPS 5, and a reasonable and effective layout is carried out according to the system electrical function design to achieve the system power distribution reliability requirements.

External AC power is introduced into the distribution box from the AC input terminal 13. In the distribution box, the AC current is transmitted to the molded case circuit breaker 2 after passing through the copper bus 15, and the molded case circuit breaker 2 then transmits the current to the relay 4 and UPS5 respectively. The UPS5 eventually transmits the current to the plug-in output terminal 11 connected to the more important power supply circuits such as lighting, control power supply, and BMS power supply. The relay 4 eventually transmits the current to the output terminal 11 such as the cooling fan. In addition, the AC input terminal 13 also transmits current to the PCS AC side. As Figure 4 As shown, QF1 in this embodiment adopts Schneider 4P circuit breaker, QF2, QF3, QF4, QF5 adopt Schneider small circuit breaker 1P+N, L1, L2, L3, N are 4P AC terminals, and P+, P- are 2P DC terminals.

[0041] After the transformation of this embodiment is completed, a UPS device is installed inside the distribution box, which not only meets the power reliability of the system, but also saves the space of the energy storage cabinet, and at the same time increases the original 200kWh energy storage system to 215kWh, greatly improving the product space utilization, product energy density and product economy.

[0042] To sum up, the utility model adds a UPS in the distribution box so that the distribution box itself has a backup power supply function, so it can provide safe and reliable power supply to the control system, heat dissipation system, temperature control system and fire protection system of the industrial and commercial storage machine, saving the space occupied by the original UPS device of the industrial and commercial storage machine, thereby improving the product energy density and space utilization of the industrial and commercial storage machine, making the industrial and commercial storage machine more compact, more integrated and more competitive.
