Abstract
The utility model discloses a bus duct cover plate including a straight edge and protruding edges bending inwards from the two ends of the straight edge, reinforcing ribs having the function of heat radiation are arranged at the outer side of the straight edge, the bus duct cover plate is formed by the cold bending of a aluminium magnesium alloy plate. The bus duct cover plate is simple in structure and convenient in machining, the reinforcing ribs extending in the horizontal direction are arranged on the straight edge of the cover plate, thereby improving the integral strength of the cover plate; in addition, the protruding edges arranged at the two ends of the straight edge can clamp and connect with a matched bus duct side plate to be free of bolts and less in the use of components, thereby improving the assembling efficiency.
Description
Technical field
The utility model relates to a kind of bus duct, is specifically related to a kind of bus duct cover plate.
Background technology
At present, bus is increasing to be used by electric power system, and the seal request of bus is very high; In the prior art; Bus duct system is an efficient power distribution equipment of carrying electric current, has especially adapted to the needs of increasingly high building and large-scale plant economical rationality distribution, so is widely used in being connected of low-voltage distribution panel and large and medium-sized load; Like modern workshop, factory building and skyscraper, be particularly suitable for the workshop that product is changeable, equipment is intensive.
Bus duct of the prior art is generally by upper and lower cover plate, left and right side plate, and supporting base and busbar are formed; Busbar embeds in the supporting base, and side plate and cover plate are in the same place with its sealing and fixing of spiral shell, is lined with sealing gasket between side plate and the cover plate contact-making surface; So just require cover plate intensity to get well, and the cover plate that uses now is a plane institution movement; There is aduncate flanging at its two ends, and the bus cover plate of this structure is in the bus running, because the vibrations that electric power produces; Make the intensity decreases of bus cover plate, thereby its degree of protection is reduced, the bus cover plate damages easily.
The utility model content
The utility model provides a kind of mechanical strength high, simple in structure bus duct cover plate.
The technical scheme of the utility model: a kind of bus duct cover plate, comprise the chimb that straight flange and straight flange inward at both ends are crooked, the straight flange arranged outside has the reinforcement of heat sinking function.
Said reinforcement extends along bus duct cover plate length direction, and quantity is the 2-3 bar.
Said reinforcement cross section is rectangular or trapezoidal, and width is the 1/6-1/8 of straight flange width.
Said bus duct cover plate is by almag plate clod wash machine-shaping.
The technique effect of the utility model: the bus duct covering plate structure of the utility model is simple, easy to process, is provided with the reinforcement that horizontal direction is extended on the cover plate straight flange, has improved the cover plate bulk strength; The chimb that the straight flange two ends are provided with can be connected with supporting bus duct side plate engaging, need not bolt, reduces the use of parts, has improved efficiency of assembling.
Description of drawings
Fig. 1 is the utility model cutaway view;
Fig. 2 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Like Fig. 1, shown in Figure 2, the bus duct cover plate comprises straight flange 1 and the crooked chimb 2 of straight flange 1 inward at both ends, and straight flange 1 arranged outside has the reinforcement 3 of heat sinking function, and said chimb 2 is connected with the groove engaging of supporting bus duct side plate, and fluid sealant seals.
Said reinforcement 3 extends along bus duct cover plate length direction, and quantity is the 2-3 bar.
Said reinforcement 3 cross sections are rectangular or trapezoidal, and width is the 1/6-1/8 of straight flange 1 width.
Said bus duct cover plate is by almag plate clod wash machine-shaping, and length can reach about 6 meters, and convenient the installation reduced the use of connector in the installation process, thereby practiced thrift cost.
