Abstract

The utility model provides a low-voltage power distribution cabinet. The low-voltage power distribution cabinet comprises a cabinet body the inside of which is provided with electrical components, an upper cover that is arranged on the top of the cabinet body and a busbar clamp that is fixed in the cabinet body; one side of the upper cover is hinged on the cabinet body and the other side is tightly locked with and matches the cabinet body; the busbar clamp is fixed in the cabinet body under the upper cover and consists of an upper busbar clamp and a lower busbar clamp that are semi-symmetric; the top part of the cabinet body is provided with a slinger; and the upper part of a standing beam close to the slinger is fixedly provided with a stiffener. The low-voltage power distribution cabinet has the following beneficial effects: the upper cover can be easily opened; no matter how small the space on the spot is for installing the low-voltage power distribution, the copper row of busbar can be quite easily installed from the top of the cabinet only after the upper cover is opened, the bolt is disassembled, and the busbar clamp is disassembled. The fixed arrangement of the stiffener on the upper part of the standing beam can increase the bearing strength of the standing beam so as to improve the overall strength of the low-voltage power distribution cabinet; and the stiffener has the advantages of simplicity, low costs and so on.

Description

Low-voltage distribution cabinet

Technical field

The utility model relates to low-voltage distribution cabinet.

Background technology

Summary of the invention

The purpose of this utility model is to overcome the deficiency of above-mentioned technology, provides a kind of and can open loam cake, the convenient copper bar bus of installing, the local a kind of low-voltage distribution cabinet that increases upright beam strength.

The technical scheme that solves the problems of the technologies described above is: a kind of low-voltage distribution cabinet, and this low-voltage distribution cabinet comprises: the cabinet of electric elements is equipped with in inside; Be positioned at the loam cake of this cabinet end face; Be fixed on the bus clip in the cabinet, described loam cake one side is hinged on the cabinet, and its opposite side cooperates with cabinet locking; Described bus clip is fixed in the cabinet below the loam cake, and this bus clip is to be pressed from both sides by the Up Highway UHW folder of two hemihedrism and Down Highway to constitute; At the cabinet top suspension ring are arranged, the Li Liang top of close suspension ring is set with reinforcement.

The beneficial effects of the utility model are: the loam cake of the utility model low-voltage distribution cabinet can be easy to open, when this low-voltage distribution cabinet is installed, how petty narrow no matter the space of erecting bed is, as long as open loam cake, the bolt of dismantling, lay down the Up Highway UHW folder, the copper bar bus can be installed very easily from the low-voltage distribution cabinet end face.In addition, be set with reinforcement on Li Liang top, increase the bearing strength of upright beam, make the whole intensity that improves of low-voltage distribution cabinet, the reinforcement syndeton has simply, low cost and other advantages.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

Fig. 1 is the front view of the utility model partial cutaway; Fig. 2 is that Fig. 1 median generatrix folds up big partial sectional view; Fig. 3 is the vertical view of Fig. 2; Fig. 4 is the vertical view of Fig. 1; Fig. 5 is an A-A cutaway view among Fig. 1.

To shown in Figure 5, the utility model provides a kind of low-voltage distribution cabinet 30 as Fig. 1, and this low-voltage distribution cabinet 30 comprises: the cabinet 21 of electric elements is equipped with in inside; Be positioned at the loam cake 1 of these cabinet 21 end faces; Be fixed on the bus clip 20 in the cabinet 21.

As Fig. 1, shown in Figure 4, described loam cake 1 one sides are hinged on cabinet 21 tops, and its opposite side cooperates with cabinet 21 lockings; Described bus clip 20 is fixed in the cabinet 21 below the loam cake 1, and this bus clip 20 is to be constituted by the Up Highway UHW folder 4 of two hemihedrism and Down Highway folder 5; At cabinet 21 tops suspension ring 16 are arranged, upright beam 9 tops of close suspension ring 16 are set with reinforcement 15.

Described loam cake 1 one sides are hinged with hinge 7 and cabinet 21, and its opposite side is provided with the lock 8 that cooperates with cabinet 21 lockings.When low-voltage distribution cabinet of the present utility model dispatches from the factory loam cake 1 securely is locked in cabinet 21 tops, can be easy to open when installation need be opened.
