Abstract
The utility model provides a low-voltage distribution cabinet bus protective cover capable of preventing eddy current. The protective cover comprises an integrated aluminum-magnesium alloy cover body which is a U-shaped accommodation cavity. At least two opposite upturned edges are arranged at the open end of the cover body. A connecting part for connection with a switch cabinet is arranged on each upturned edge. The cover body is cubic. The surface of each upturned edge is a horizontal plane. The connecting part on each upturned edge of the cover body is a connecting hole for the connection with the switch cabinet. The stability of connection between the bus protective cover and a switch cabinet body can be improved, the overall weight of the switch cabinet can be decreased, and the eddy current produced in the electrified running of a vertical bus is prevented; and due to the adoption of a die pressing technology, standardized production can be realized, an assembly process is simple, and production efficiency can be improved.
Description
[technical field]
The utility model relates to a kind of device of low-voltage distribution cabinet, particularly a kind of bus protective cover of low-voltage distribution cabinet.
[background technology]
Low pressure drawer-type switch cabinet is applicable to the power plant, electric substation, and industrial and mining enterprises, places such as communications and transportation, control, illumination, the electric energy that is mainly used in distribution, motor and power consumption equipment changed, power back-off.The tank bracket of switch cubicle adopts the C type beam of standard module and application specific architecture assembly to form, and is formed by connecting mutually through self-tapping lock screw is fastening, needs by the scheme variation again; Add corresponding door, shrouding, dividing plate; The bus protective cover, mounting bracket, and bus; Parts such as functional unit are assembled into a complete device.
Low pressure drawer-type switch cabinet all need be provided with vertical bus row because of the needs of structure, and vertical bus row's exterior protection cover.Present protective cover has two kinds basically, and first kind of two blocks of side plates and cover plate by iron plate or galvanized sheet (covering the aluminium zine plate) system formed a containing cavity, and said two blocks of side plates and a cover plate are to link together through bolt, and bus row place in the containing cavity.But there is following shortcoming in this kind way: iron plate or galvanized sheet (covering the aluminium zine plate) needs are processed once more, and like shear, punching press, bending even must spray, manufacturing procedure is loaded down with trivial details; Whole heavy; And cost of labor is high, relates to the problem that spraying also maybe influence ecological environment, and bus row is connected through bolt exist on the sidewall of containing cavity and connects unsettled shortcoming; Should adopt ferrous material simultaneously; In bus row energising running, be easy to generate eddy current loss, influence the loss of product safety performance and energy consumption;
It is another kind of that extrusion modling is a cover body through mould by the PVC material; Said cover body is barrel-shaped containing cavity; Bus row place in the containing cavity; But following shortcoming is arranged: have basically no anti-fire-retardant performance, even add the flame retardant products that other synthetic materials are processed, but because of the shortcoming of plastic products protection insufficient strength.
[summary of the invention]
The technical problem that the utility model will solve; Be to provide a kind of low-voltage distribution cabinet bus protective cover that prevents that eddy current from producing, it can improve connection stability between bus protective cover and switch cabinet, and easy for installation; Enhance productivity, can also prevent the generation of eddy current simultaneously.
The utility model is achieved in that a kind of low-voltage distribution cabinet bus protective cover that prevents that eddy current from producing; It comprises an integrated almag cover body; Said cover body is a U-shaped containing cavity; The openend of said cover body is provided with the outer of at least two correspondences and turns edge, said outer turn edge to be provided be used for the connecting portion that is connected with the switch cabinet.
Further, said cover body is side's shape.
Further, the said outer surface that turns edge is a horizontal plane.
Further, the connecting portion on said cover body turns edge outward is to be used for the connecting hole that is connected with the switch cabinet.
Further, evenly be provided with a plurality of ventilation holes on the said cover body.
The advantage of the utility model is:
The connecting hole of the utility model is positioned on outer the turning edge, and the particularly said outer surface that turns edge is a horizontal plane, therefore when the switch cabinet is connected with the bus protective cover, has just improved connection stability, is not easy displacement, perhaps bolt failure;
The utility model adopts the one-body molded extrusion technique of mould, but standardized production, and do not need secondary operations, and reduce influence ecological environment, adopt hydronalium simultaneously, can prevent that eddy current from producing, the installation production process is simple, and production efficiency is high.
[description of drawings]
Combine embodiment that the utility model is further described with reference to the accompanying drawings.
Fig. 1 is the structural representation of the utility model.
[embodiment]
See also shown in Figure 1ly, the embodiment of the utility model is carried out detailed explanation.
Like Fig. 1, a kind of low-voltage distribution cabinet bus protective cover that prevents that eddy current from producing of the utility model, it comprises an integrated almag cover body 1, the material of said cover body 1 is a hydronalium.Said cover body 1 is a U-shaped containing cavity, and the said cover body 1 of the utility model is side's shape.Said cover body 1 evenly is provided with rectangular ventilation hole 4.The openend of said cover body 1 is provided with the outer of two correspondences and turns edge 2; Said outer turning edge 2 is provided with and is used for the connecting portion that is connected with the switch cabinet; Said bus protective cover is connected with the switch cabinet through connecting portion, and connected mode can adopt buckle structure, chute structure and screw fixed structure.What the utility model adopted is bolted structure.Be that said outer 2 the surface of turning edge is a horizontal plane, said outer turning edge 2 is provided with and is used for the connecting hole 3 that is connected with the switch cabinet.Then said bus protective cover is linked together through bolt and switch cabinet, therefore when the switch cabinet is connected with the bus protective cover, just improved connection stability, be not easy displacement, perhaps bolt failure.
The utility model adopts the one-body molded extrusion technique of mould, but therefore standardized production, production process is simple, and production efficiency is high; Base material uses hydronalium simultaneously, and its material has following characteristics: a, the hydronalium surface does not need aftertreatment (as: spraying etc.), and resistance to corrosion prolongs 10-20 than galvanized steel plain sheet after the aluminium surface anodic oxidation, helps the biological environment balance; The almag shell of b, weak magnetic can not produce eddy current and magnetic hysteresis loss, has improved current capacity; C, almag shell heat-sinking capability are strong, have also improved current capacity; D, almag shell electrostatic screen are made good use of, and aluminium section bar can be made complicated shape, and rigidity is better than steel plate bending, but large span production and installation; E, in light weight, easy for installation, good looking appearance can keep for a long time.
The above; Be merely the utility model preferred embodiment; So can not limit the scope that the utility model is implemented according to this, the equivalence of promptly doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
