[0056] According to some embodiments of the present application, optionally, the energy storage power station further includes a circuit breaker 10. The high-voltage box 3 is electrically connected to the circuit breaker 10, and the circuit breaker 10 is electrically connected to the energy storage converter 5. The circuit breaker 10 is installed on the second mounting rack 8, and the circuit breaker 10 is installed above the energy storage converter 5.

[0057] In this way, the circuit breaker 10 is installed on the energy storage converter 5, and the circuit breaker 10 is located at the top of the second mounting rack 8, making full use of the space above the second mounting rack 8, utilizing the space in the vertical direction, and reducing the floor area of the energy storage power station in the horizontal direction.

[0060] According to some embodiments of the present application, optionally, the height of the first mounting rack 2 is greater than the height of the second mounting rack 8.

[0061] In this way, by setting mounting racks with different heights, the layout of the energy storage devices can be better arranged and organized, facilitating maintenance and installation. The lower mounting rack is convenient for staff to enter and operate in the space, making maintenance and repair easier.

[0062] Different from the prior art, the technical solution of the present application arranges the first mounting rack 2 and the second mounting rack 8 side by side on the base 1, and fixes the high-voltage box 3 on the middle layer board 21 of the first mounting rack 2. Compared with the prior art where the high-voltage box 3 is set at the top position, the height of the high-voltage box 3 is reduced, which is convenient for staff to operate.
