Abstract
The invention discloses a detachable top cover mounting structure of a low-voltage power distribution cabinet, which comprises a support, support beams and a top cover, wherein the support is of an inverted L-shaped structure and is fixed on the front side and the rear side of a main bus chamber of the power distribution cabinet through bolts, the support beams are mounted on the support through bolts and are kept flush with a top cross beam of a cabinet body, and the top cover is mounted on the support beams and the top cross beam and is fixedly connected with the support beams and the top cross beam through bolts. The electric bus bar has a simple structure, the support and the support beam as well as the support beam and the top cover are fixedly installed through bolts and are easy to disassemble, so that the main bus bar is convenient to install, the high bearing capacity of the support beam enables constructors not to easily generate the phenomenon of treading depression when moving on the cabinet top, and the electric gap between the top cover and the main bus bar is effectively ensured.
Description
Technical Field
The invention relates to the technical field of distribution equipment, in particular to a detachable top cover mounting structure of a low-voltage distribution cabinet.
Background
When the top cover of the existing MNS, GCK and GCS type low-voltage power distribution cabinet is designed, a main bus chamber is usually designed into an open structure for the convenience of installation of a main bus bar behind the cabinet, and the two sides of the top cover are reinforced by bending. But actually when arranging the construction installation at female, constructor can stand and move about on the top cap, and open-type top cap intensity is not enough, often can appear trampling the phenomenon of collapsing, directly leads to the electric clearance that top cap and main female row connect not enough, has very big potential safety hazard.
Disclosure of Invention
The invention aims to provide a detachable top cover mounting structure of a low-voltage power distribution cabinet, which has stronger bearing capacity, is convenient for mounting a main bus bar and does not interfere with the normal movement of mounting constructors, aiming at overcoming the defects of the prior art.
in order to achieve the purpose, the invention adopts the technical scheme that: the utility model provides a detachable top cap mounting structure of low-voltage distribution cabinet, includes support, a supporting beam and top cap, the support is type of falling L structure, through the bolt fastening both sides around the switch board main bus-bar room, a supporting beam passes through the bolt and installs on the support and keep the parallel and level with cabinet body top crossbeam, the top cap is installed on a supporting beam and top crossbeam, through bolt and a supporting beam and top crossbeam fixed connection.
The electric bus bar has a simple structure, the support and the support beam as well as the support beam and the top cover are fixedly installed through bolts and are easy to disassemble, so that the main bus bar is convenient to install, the high bearing capacity of the support beam enables constructors not to easily generate the phenomenon of treading depression when moving on the cabinet top, and the electric gap between the top cover and the main bus bar is effectively ensured.

In the figure: 1-a scaffold; 11-bolt mounting holes; 2-a support beam; 21-a top panel; 22-bottom panel; 23-side panel; 24-end panels; 25-bolt mounting holes; 26-avoiding the notch; 3-a top cover; 4-top beam.
Detailed Description
The invention will be further described in detail with reference to examples of embodiments shown in the drawings to which, however, the invention is not restricted.
As shown in fig. 1, the detachable top cover mounting structure of the low-voltage power distribution cabinet provided by the invention comprises a support 1, a support beam 2 and a top cover 3, wherein the support 1 is of an inverted L-shaped structure and is fixed on the front side and the rear side of a main bus chamber of the power distribution cabinet through bolts, the support beam 2 is mounted on the support 1 through bolts and is flush with a top cross beam 4 of a cabinet body, and the top cover 3 is mounted on the support beam 2 and the top cross beam 4 and is fixedly connected with the support beam 2 and the top cross beam 4 through bolts.
As shown in fig. 2, the support beam 2 is composed of a top panel 21, a bottom panel 22 opposite to the top panel 21, two side panels 23 connecting the top panel 21 and the bottom panel 22, and end panels 24 connecting the top panel 21, the bottom panel 22 and the two side panels 23, wherein two bolt mounting holes 25 are respectively formed at two ends of the bottom panel 22 of the support beam 2, bolt mounting holes 11 are also formed in the transverse panels of the bracket 1 and correspond to the bolt mounting holes 25 in the bottom panel 22 of the support beam 2, and are used for mounting bolts to fix the bracket 1 and the support beam 2, and two avoidance notches 26 are respectively formed at two ends of the top panel 21 of the support beam 2 and vertically correspond to the bolt mounting holes 25 at two ends of the bottom panel 22 for facilitating the installation of the bolts.
In the invention, the thickness of the support 1 is 2.5mm, the thickness of each panel forming the support beam 2 is 2.0mm, so that the support beam 2 can bear 200 jin of heavy objects without deformation, when the main busbar is installed, the top cover 3 is firstly disassembled, the installation bolt between the support beam 2 and the support 1 is taken down through the avoidance gap 26 right above the cabinet top, the support beam 2 is taken down, and then the main busbar can be installed.
The electric bus bar has a simple structure, the support 1 and the support beam 2 as well as the support beam 2 and the top cover 3 are fixedly installed through bolts and are easy to disassemble, so that the main bus bar is convenient to install, the high bearing capacity of the support beam 2 enables constructors not to easily tread and dent when moving on the top of the bus bar, and therefore the electric gap between the top cover 3 and the main bus bar is effectively guaranteed.
