Description

TECHNICAL FIELD

[0001] The utility model relates to the field of switchgear, more specifically, to an indoor AC metal armored movable switchgear small busbar room. BACKGROUND

[0002] The small busbar room of KYN44-12 indoor AC metal armored movable switchgear is generally placed on the cabinet top as an independent compartment. The structure mainly consists of a cabinet top cover, a brow, a groove plate and a small busbar room cover plate; and the cabinet top groove plate and the small busbar room cover plate are generally connected by hinges, which can be flipped for the installation of the small busbar and its terminal wiring.

[0003] However, in the engineering scheme, if the cabinet top wiring and the cabinet top bridge design are adopted, or the switch cabinet is installed in the prefabricated cabin, the small busbar room cover plate may not be flipped, which makes the hinges unable to play their due role. This will result in two different structural forms of the small busbar compartment, not only increasing the complexity and diversity of the structure, but also relatively high cost of the two hinges, thereby leading to time-consuming and laborious installation and maintenance process.

[0007] As a further description of the above technical scheme:

[0008] A handle is welded to the top of the cover plate.

[0009] As a further description of the above technical scheme:

[0010] The side view sections of the brow plate and the groove plate are both C-shaped, and the top heights of the brow plate and the groove plate are flush.

[0011] As a further description of the above technical scheme:

[0012] The front surface of the brow plate is convex, and the front surface of the brow plate is flush with the cabinet door of the front surface of the switch cabinet body.
