Description
Technical field
The utility model relates to a kind of electric equipment, particularly a kind of low voltage drawing-out switching carbinet back door.
Background technology
Switch cubicle is a kind of electric equipment, and switch cubicle outside line is introduced into master switch in cabinet, then enters sub-control switch, and each shunt needs to arrange by it.As instrument, automatic control, motor magnetic switch, various A.C. contactors etc., what have also establishes hyperbaric chamber and low-pressure chamber switch cubicle, is provided with high voltage bus, as power plant etc., the low-frequency load reduction be also provided with as protecting capital equipment had.
The Main Function of switch cubicle carries out generating electricity in electric power system, transmits electricity, in the process of distribution and electric energy conversion, carries out folding, control and protection power consumption equipment.Parts in switch cubicle mainly contain the compositions such as circuit breaker, isolating switch, on-load switch, operating mechanism, instrument transformer and various protective devices.The sorting technique of switch cubicle is a lot, as being divided into withdraw-type switch cabinet and fixed switching cabinet by circuit breaker mounting means; Or according to the difference of cabinet body structure, open type switch cubicle, metal closed switch cabinet and metal enclosed armoured switch cabinet can be divided into; High-tension switch cabinet can be divided into again, Medium Voltage Switchgear and low-tension switch cabinet etc. according to electric pressure difference.Mainly be applicable to various different occasion such as power plant, transformer station, petrochemical industry, metallurgical steel rolling, industry light industry textile industry, industrial enterprise and residential quarters, skyscraper etc.
Switch cubicle all can be provided with a back door, so that the installation of the parts of inside or maintenance.The back door of existing switch cubicle, structure is simple, in transport, use procedure, is squeezed or collides, easily deforming, have impact on the useful life of switch cubicle.After distortion, also easily damage the parts of inside switch cabinet.
Utility model content
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides a kind of novel low voltage drawing-out switching carbinet back door.
To achieve these goals, the measure taked of the utility model:
A kind of low voltage drawing-out switching carbinet back door, comprises switch cubicle, described switch cubicle is provided with back door, and the panel at back door adopts concave surface and convex surface to be arranged alternately;
Described concave surface and convex surface vertically arrange or arrange along horizontal transverse direction;
Be set to vertical concave surface in the middle of the panel at described back door, both sides are set to vertical convex surface;
The panel upper/lower terminal at described back door is all provided with stiffener;
Described back door adopts stainless steel alloy material to make;
Described concave surface and convex surface uniform circular arcs face, its circular arc curvature is equal;
Inside described back door, transverse weld or riveted joint have some reinforcements.
The beneficial effects of the utility model: practical, production cost is low, easy to use, and concavo-convex staggered design, enhances the mechanical strength at back door, extends the useful life of product, effectively can prevent crimp.
Accompanying drawing explanation
Fig. 1, structural representation of the present utility model.
Embodiment
A kind of low voltage drawing-out switching carbinet back door, comprises switch cubicle 1, described switch cubicle 1 is provided with back door 2, and the panel at back door 2 adopts concave surface 3 and convex surface 4 to be arranged alternately.
The panel at back door 2 adopts concave surface 3 and convex surface 4 to be arranged alternately, and enhances the mechanical strength at back door, when being subject to external force, not yielding.Better protect the parts of its inside.Also more attractive in appearance.
Described concave surface 3 and convex surface 4 vertically arrange or arrange along horizontal transverse direction, and usual employing is vertically arranged.
Be set to vertical concave surface 3 in the middle of the panel at described back door 2, both sides are set to vertical convex surface 4.Outward appearance is clean and tidy, is convenient to packaging, transport and installs.
The panel upper/lower terminal at described back door 2 is all provided with stiffener 5, further increases its mechanical strength, firmly, more not yielding.。
Described back door 2 adopts stainless steel alloy material to make.When outdoor application, running into rainwater immersion also can not corrosion.
Described concave surface 3 and convex surface 4 uniform circular arcs face, its circular arc curvature is equal.
Inside described back door 2, transverse weld or riveted joint have some reinforcements, further increase its mechanical strength, firmly, more not yielding.
