Abstract
The utility model discloses an open-type top cover for a low-voltage cabinet. The top cover is divided into a front cover plate, a middle cover plate, and a back cover plate, wherein the front cover plate (2) and the back cover plate (9) are fixed on a cabinet body of a switch cabinet through suspension rings (1), one end of the middle cover plate (7) is connected with the back cover plate (9) through a hinge (8), the other end of the middle cover plate (7) is fixed on a riveting nut (3) on the front cover plate (2) through a bolt (4), and a central section of the middle cover plate (7) is protruded upward for ventilation and heat dissipation. The top cover of the utility model effectively solves the problems that: when the existing top cover for a cabinet body of a low-voltage switch cabinet is dismounted, parts (such as the suspension rings, upper frames, etc. ) of the switch cabinet need to be dismounted at first; in addition, by adopting the top cover of the utility model, a main bus can be directly put into a bus clip of the switch cabinet, thus the history that the original bus of the switch cabinet only can be penetrated from a side surface is ended, and a new situation that the main bus can be put into the switch cabinet from a top of the cabinet is initiated. According to the top cover of the utility model, installation of the bus is not restricted by an extraneous space, installation and dismounting for the top cover are convenient, and many defects of the original switch cabinet are overcome.
Description
Technical field
The utility model relates to the low-voltage distribution cabinet in a kind of electrical power distribution system switchgear, and is special relevant with the top cover of low-voltage distribution cabinet.
Background technology
Low-voltage distribution cabinet is widely used in electric power occasions such as the low-voltage-powered control centre of industries such as the power plant of big single-machine capacity, extensive petrochemical industry and motor control center.Its cabinet framework adopts assembly unit and part Type of Welding, and general employing of its top cover is designed to an integral body by the cabinet profile.In actual applications, these equipment to the user scene when main bus bar is worn in the cupboard side, because of switch cubicle too near or the switchgear house overall space is limited apart from wall, the busbar of every fixed length can't pass bus clip from the side successively, to have to solve in order finishing to install, to have a strong impact on installation progress and architectural appearance like this with mode such as demolish walls, punch.Particularly in recent years, country implements strict land policy, and invisible also has requirement to switchgear house space utilization in the new projects.But the side of original switch is worn row's formula structure and is not changed, and this has become the problem that presses for solution today.
The utility model content
The utility model is to design a kind of top cover to open from the cabinet top, and main bus bar is put into the open type low-voltage cabinet top cover of switch cubicle from the cabinet top.
The technical solution adopted in the utility model is: a kind of open type low-voltage cabinet top cover, it is characterized in that, three cover plates before, during and after top cover is divided into, front shroud and back shroud are fixed on the switch cabinet body by suspension ring, cover plate one end is connected with back shroud by hinge, on the riveting nut on the front shroud, the cover plate middle part raises up with ventilation and heat the other end by bolt.
Be used as the cover plate of unlatching in the cap structure, only need turn on riveting nut and bus clip during unlatching, just can easily finish the operation that bus is installed from the cabinet top downwards; In the middle of during cover plate closing, the peculiar side girders like double-vane of its both sides supports for cabinet when four jiaos of liftings of cabinet with brute force, lifting intensity is good, the ventilation and heat effect is strong; Adopt the syndeton of riveting nut, guaranteed that top cover can be used as repeatedly unlatching and uses.
The open type low-voltage cabinet top cover that the utility model provides, solved the low voltage switchgear body top cover of present use effectively, when dismantling top cover, need lay down many troubles of the part such as suspension ring, brows of switch cubicle earlier, and can make main bus bar directly put into the switch cubicle bus clip from the cabinet top, the history that original switch cubicle bus that is through with can only side be worn has been opened main bus bar is put into switch cubicle from the cabinet top the beginning.Bus is installed and not to be subjected to extraneous spatial limitation, and installation, convenient disassembly, has overcome former many drawbacks with switch cubicle.Make simple, easy to operate.
Description of drawings
Accompanying drawing is the structural representation of the utility model open type low-voltage cabinet top cover.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, suspension ring 2, front shroud 3, riveting nut 4, bolt 5, bus clip 6, bus 7, cover plate 8, hinge 9, back shroud
As shown in drawings, three cover plates before, during and after the utility model open type low-voltage cabinet top cover is divided into, front shroud 2 and back shroud 9 are fixed on the switch cabinet body by suspension ring 1, and cover plate 7 one ends are connected with back shroud 9 by hinge 8, and the other end is fixed on the riveting nut 3 on the front shroud 2 by bolt 4.Cover plate 7 middle parts raise up with ventilation and heat.
When bus 6 is installed, bolt 4 is turned on, started cover plate 7 and bus clip 5 is opened, bus 6 is directly put into bus clip 5 from the cabinet top.
