However, during the actual construction and installation of the busbar, the construction personnel will stand on the top cover and move around. The open top cover is not strong enough, and the phenomenon of stampede and collapse often occurs, which directly leads to insufficient electrical clearance between the top cover and the main busbar. There is a great security risk

Embodiment Construction
[0009] The present invention will be described in further detail below in conjunction with the embodiments in the accompanying drawings, but this does not constitute any limitation to the present invention.
[0010] Such as figure 1 As shown, a detachable top cover installation structure of a low-voltage power distribution cabinet provided by the present invention includes a bracket 1, a support beam 2 and a top cover 3. The bracket 1 is in an inverted L-shaped structure and is fixed to the power distribution cabinet by bolts. On the front and back sides of the main busbar room, the support beam 2 is installed on the bracket 1 by bolts to keep it flush with the top beam 4 of the cabinet body, and the top cover 3 is installed on the support beam 2 and the top beam 4, and is supported by the bolts. The beam 2 and the top beam 4 are fixedly connected.
[0011] Such as figure 2 As shown, the support beam 2 is composed of a top panel 21, a bottom panel 22 opposite to the top pan...

Abstract
The invention discloses a detachable top cover mounting structure of a low-voltage power distribution cabinet. The structure comprises a support, a support beam and a top cover, wherein the support isof an inverted-L-shaped structure and is fixed to the front side and the rear side of a main bus chamber of the power distribution cabinet through bolts, the support beam is installed on the supportthrough bolts and is aligned with a top cross beam of a cabinet body, and the top cover is installed on the support beam and a top cross beam and is fixedly connected with the support beam and the topcross beam through bolts. The structure is simple, the support and the support beam as well as the support beam and the top cover are installed and fixed through bolts, so the structure is easy to disassemble, and the main busbar is convenient to install; the high-strength bearing capacity of the support beam enables constructors not to easily tread and sink when the constructors move on the cabinet top, and the electrical gap between the top cover and the main busbar is effectively guaranteed.
Description
technical field [0001] The invention relates to the technical field of power distribution equipment, and more specifically relates to a detachable top cover installation structure of a low-voltage power distribution cabinet. Background technique [0002] When designing the top cover of the existing MNS, GCK, and GCS low-voltage power distribution cabinets, in order to facilitate the installation of the main busbar behind the cabinet, the main busbar room is usually designed as an open structure, and the two sides of the top cover are reinforced by bending. However, during the actual construction and installation of the busbar, the construction personnel will stand on the top cover and move around. The open top cover is not strong enough, and the phenomenon of stampede and collapse often occurs, which directly leads to insufficient electrical clearance between the top cover and the main busbar. There are great security risks. Contents of the invention [0003] The purpose ...
