Abstract
The invention discloses a low-voltage bus duct side plate structure which comprises a top face and a side face. The two ends of the side face are stress enhancing structures which are curved relative to the middle of the side face. By means of the low-voltage bus duct side plate structure, the shear strength of a bus side plate can be effectively improved so that the short-circuit strength of bus products can be improved, the material cost of the bus side plate can be lowered, and meanwhile the low-voltage bus duct side plate structure is convenient to implement, and attractive and simple in appearance.
Description
Technical field
The present invention relates to a kind of low voltage bus bar groove lateral plate structure, belong to power transmission and distribution technical field.
Background technology
Bus is as important equipment for power transmission and distribution, has irreplaceable effect, and be widely used in all trades and professions such as automobile, metallurgy, electronics, petrochemical industry, business, real estate in people's production, life.The competition in bus market, the new material of enhancing product performance, use of the new technology, reduces costs and becomes industry development direction.
Bus bar products is in the market at low voltage bus bar groove side plate design aspect, generally adopt simple " U-shaped " structure (as shown in Figure 1), do not contemplate the force-bearing situation of bus under normal operation or short-circuit conditions, the Mechanical Builds of the especially suffered shear stress of bus side plate, and appropriate design bus side plate.Under generally pursuing cheaply situation in manufacturer, be easy to cause bus bar products interior quality, especially the decline of short-circuit strength index.
Summary of the invention
For the problems referred to above, the object of the invention is to propose a kind of low voltage bus bar groove lateral plate structure, reducing under the prerequisite of material cost, improve or do not reduce the shear strength of bus side plate, thereby ensure bus bar products short-circuit capacity.
To achieve these goals, technical scheme of the present invention is as follows:
Low voltage bus bar groove lateral plate structure, comprises end face and side, it is characterized in that, the two ends of described side are that the bending stress compared with middle part, side strengthens structure.
In the present invention, described side is the arcuate flanks of protruding to generatrix direction, and the thickness of arcuate flanks reduces to centre gradually from two ends.
In the present invention, be provided with to strengthen the reinforcement of bending stress ability to bear between the two ends of described side and end face, described reinforcement is connected with side on one side, is connected on one side with end face.Further, described reinforcement is rectangular configuration.Described reinforcement is arcuate structure.Described reinforcement is one or more mixed structures in arc, rectangle, triangle.
The design theory of low voltage bus bar groove lateral plate structure is according to being: the side plate to existing " U-shaped " structure carries out force analysis, the electric power q that bus produces under alternating current effect perpendicular to the stepless action of side plate direction on side plate, side plate two ends are fixed by cover plate, side plate is at the suffered and reciprocal shearing counter-force of the electric power q F with cover plate tie point, according to analyzing F=qh/2, learn the distribution situation of the suffered shearing force F of side plate, maximum shear stress qh/2 occurs in side plate two ends, and shearing force F is reduced to centre gradually by two ends; Side plate maximal bending moment is in the centre of side plate short transverse, and its value is qh2/8, and the suffered Bending moment distribution situation of side plate is for reducing gradually from the middle to both ends; According to the distribution of side plate shearing force F and moment of flexure, under the prerequisite that meets requirement of strength, side plate middle part for Bending stress little weaken structure, side plate two ends are the enhancing structure that Bending stress is large.
Adopt after the present invention, can effectively improve the shear strength of bus side plate, and then improve the short-circuit strength of bus bar products, reduce the material cost of bus side plate, to implement convenient simultaneously, good looking appearance, succinct.
Feature of the present invention can be consulted the detailed description of the graphic and following better execution mode of this case and be obtained and be well understood to.

Embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, further set forth the present invention below in conjunction with specific embodiment.
Low voltage bus bar groove lateral plate structure, comprises end face and side, and the two ends of side are that the bending stress compared with middle part, side strengthens structure.
The design theory of low voltage bus bar groove lateral plate structure is according to being: the side plate to existing " U-shaped " structure carries out force analysis, the distribution of the suffered shearing force of side plate as shown in Figure 5, the electric power q that bus produces under alternating current effect perpendicular to the stepless action of side plate direction on side plate, side plate two ends are fixed by cover plate, side plate is at the suffered and reciprocal shearing counter-force of the electric power q F with cover plate tie point, according to analyzing F=qh/2, the distribution of the suffered shearing force of side plate as shown in Figure 6, learn the distribution situation of the suffered shearing force F of side plate, maximum shear stress qh/2 occurs in side plate two ends, and shearing force F is reduced to centre gradually by two ends, Fig. 7 is the suffered Bending moment distribution schematic diagram of the side plate in Fig. 5, and side plate maximal bending moment is in the centre of side plate short transverse, and its value is qh2/8, and the suffered Bending moment distribution situation of side plate is for reducing gradually from the middle to both ends, according to the distribution of side plate shearing force F and moment of flexure, under the prerequisite that meets requirement of strength, side plate middle part for Bending stress little weaken structure, side plate two ends are the enhancing structure that Bending stress is large.
