The busbar assembly 30 includes a horizontal busbar 31 and a vertical busbar 32 arranged inside the cabinet body 10. The horizontal busbar 31 is arranged below the disconnecting switch 20 and is arranged along the length direction of the cabinet body 10. The vertical busbar 32 is arranged between the disconnecting switch 20 and the horizontal busbar 31, and both ends of the vertical busbar 32 are respectively connected to the disconnecting switch 20 and the horizontal busbar 31. The circuit breaker 40 is used for connecting with the cables of external energy storage devices. The circuit breaker 40 is arranged inside the cabinet body 10 and is arranged below the busbar assembly 30, and the circuit breaker 40 is connected to the horizontal busbar 31.

[0040] In some embodiments of this application, the cabinet body 10 is an overall cube structure, which includes a cabinet main body 11, a front door 12, and a rear door 13.

[0041] An installation space is provided inside the cabinet main body 11 for the assembly of relevant components in the busbar cabinet 100. In some examples, the front door 12 and the rear door 13 can be rotatably connected to the cabinet main body 11 to facilitate the user to open and close the cabinet body 10 from the front side and the rear side of the cabinet body 10, so as to facilitate the user to maintain and repair the busbar cabinet 100.

This busbar cabinet can achieve the busbar connection of multiple energy storage devices by means of the lower part of the cabinet body for incoming lines and the cables being connected from bottom to top, effectively separating the incoming lines and outgoing lines, reasonably arranging each component inside the cabinet body, avoiding cable overlap, ensuring the overall safety of the busbar cabinet, and ensuring the normal use of users.

[0093] Although the present utility model has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present utility model can be embodied in many forms without departing from the spirit or essence of the utility model, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be broadly interpreted within the spirit and scope defined by the appended claims. Therefore, all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
