Abstract
The utility model discloses a large-area self-heat-dissipation copper busbar which is composed of circular arc edges (1), side grooves (2), front grooves (3) and a copper busbar main body (4). The large-area self-heat-dissipation copper busbar is characterized in that the busbar main body (4) is of a flat structure, each side circular arc edge (1) of the busbar main body (4) is of an arc-shaped structure, the front grooves (3) which are parallel to arc-shaped edges are formed both in the upper flat surface and the lower flat surface of the copper busbar main body (4), and the side grooves (3) are arranged between the upper front groove (3) and the lower front groove (3) and between each front groove (3) and each circular arc edge (2). The large-area self-heat-dissipation copper busbar is small in installation space, and simple and fast in mounting technique. Compared with a traditional copper busbar, the large-area self-heat-dissipation copper busbar is faster in heat dissipation and has a larger current unit flow area in the same size, and the service life is long.
Description
Technical field
The utility model relates to on-insulated conductor or the conductive body field that the primary element class is distinguished by shape in the electricity, refers to that especially a kind of large tracts of land is from dispelling the heat copper busbar.
Background technology
Copper busbar is widely used in switch cubicle, bus-bar system, circuit breaker, building power supply bus, large-scale electric equipment transmission of electricity etc., traditional copper busbar mostly is rectangle, because the electric current of copper busbar carrying is very big, therefore can produce a large amount of heats, cause that easily equipment or wire installation are hot, thereby cause the low service life of equipment that reaches of power transmission efficiency to shorten, conventional art adopts the area that increases copper busbar more, reduce the electric current that flows through in the copper busbar unit are, reduce the hot or reduction ambient temperature of conductor, be convenient to the equipment cooling, this dual mode all can cause production cost to improve.
The patent No.: CN201120380010.4, this patent disclosure a kind of copper busbar, comprise the copper busbar body, the outer peripheral face of described copper busbar body is provided with some raised lines, because the outer peripheral face of described copper busbar body is provided with some raised lines, this raised line has increased the sectional area of copper busbar, reduced the flow of electric current in the unit are, avoid copper busbar hot, and raised line also plays the effect of fin, has improved the heat dispersion of copper busbar, but this device and increase installing space, the equipment that is actually used in is subjected to spatial limitation bigger when installing, the device structure of particularly having finalized the design.
Summary of the invention
The utility model provides a kind of large tracts of land from the copper busbar of dispelling the heat, little, the mounting technique simple and fast of this structure installing space, and radiating rate is fast than the traditional copper bus, has bigger current unit flow area under equal volume, long service life.
For achieving the above object, the utility model has adopted following technology to realize, a kind of large tracts of land is formed from the copper busbar structure of dispelling the heat and is comprised the circular arc limit, the side groove, positive groove, the copper busbar main body, wherein the copper busbar main body is flat configuration, the side circular arc limit of copper busbar main body is configured as arc, all be provided with the positive groove on parallel arc limit on the copper busbar main body on the lower plane, at positive groove and positive groove, all be provided with the side groove between positive groove and the circular arc limit, the circular arc limit has increased radiating surface and the unitary current area of flowing through, and groove has played effect and the thermolysis of increase electric current by area too, and the lifting of this effect does not need to increase the sectional area of copper busbar.
As further restriction of the present utility model, the quantity of positive groove is 1～6, and spacing equates evenly to distribute.
As further restriction of the present utility model, the side groove is 10～90 ° with respect to the angle of inclination of positive groove, distributes by this even angle.
