The utility model has ingenious conception and convenient use, can be suitable for different breaker pile heads, and can greatly reduce the width of the cabinet by adopting the transfer pile head on the premise of meeting the installation requirement when being used for a multi-frame loop, thereby saving the cost; the pile head is perpendicular subsection, easily the heat dissipation of copper bar, effectively reduces the copper bar that female row generates heat and causes and falls the appearance.
Description
Technical Field
The utility model relates to a copper bar, in particular to a special-shaped switching copper bar, and belongs to the technical field of electrical equipment.
Background
At present, the switch pile head of frame circuit breaker in the trade adopts horizontal pile head or perpendicular pile head usually, these circuit breakers are arranged in the low voltage distribution product more, along with the development of trade, in order to save the cost, it installs on a frame to need a plurality of circuit breakers, install about adopting more, traditional way is that upper frame links main female row, lower floor's frame is connected to main female arranging through the side row, this kind of manufacturing approach cabinet width needs 800mm usually, along with the increase of electric current, cabinet body width also needs corresponding increase, relatively extravagant cost, be unfavorable for the cost reduction and efficiency of enterprise.
SUMMERY OF THE UTILITY MODEL
The utility model aims to: the problem of the cabinet width that the relation of connection leads to between row that exists to above-mentioned prior art is provided a dysmorphism switching copper bar, replaces original pile head on the former frame circuit breaker, realizes upper and lower two-layer switch direct vertical connection main bus, reduces the quantity of cabinet body width and copper bar.
In order to achieve the above object, the specially-shaped switching copper bar of the present invention has a first surface and a second surface that are perpendicular to each other, and the first surface and the second surface are connected to form a whole through a third surface.
The first surface is a long surface, the second surface is a short surface, and the third surface is an inclined surface.
Four mounting holes are arranged on the long surface, and two of the four mounting holes are close to the inclined surface.
The two mounting holes close to the inclined plane are in the shape of an outward-expanding circle, so that the fixing of the mounting screws is ensured, and the mounting screws are used for being connected with the circuit breaker.
The thickness of first face is less than the thickness of second face, the thickness of third face cooperatees rather than the thickness of the first face of connecting and second face respectively, guarantees pile head current-carrying capacity like this overlap joint even when arranging, can not lead to the pile head to generate heat because of the electric current is too big.
And the short surface is provided with three mounting holes for mounting the outgoing line copper bar.
The short sides have beveled corners on their inner edges to ensure that sufficient electrical clearance is maintained with the vertical rows.
The utility model has ingenious conception and convenient use, can be suitable for different breaker pile heads, and can greatly reduce the width of the cabinet by adopting the transfer pile head on the premise of meeting the installation requirement when being used for a multi-frame loop, thereby saving the cost; the pile head is perpendicular subsection, easily the heat dissipation of copper bar, effectively reduces the copper bar that female row generates heat and causes and falls the appearance.

Detailed Description
Example one
The structure of this embodiment is as shown in fig. 1-5, and a special-shaped adapter copper bar 5 has a first surface and a second surface that are perpendicular to each other, and the first surface and the second surface are connected by a third surface to form an integral body similar to an "L" shape. The method is mainly used for switching the low-voltage frame circuit breaker pile heads. The first face is long face 1, and the second face is short 2, and the third face is inclined plane 3. Four mounting holes 7 are arranged on the long surface 1, wherein two mounting holes close to the inclined surface are in the shape of an outward-expanding circle 8, so that the fixation of mounting screws is ensured, and the mounting screws are used for being connected with a circuit breaker. The thickness of the first face of dysmorphism switching copper bar is less than the thickness of second face, and the thickness of third face cooperatees rather than the first face of connecting and the thickness of second face respectively, guarantees pile head current-carrying capacity like this when the overlap joint is even arranged, can not heat because of the too big pile head that leads to of electric current. And three mounting holes 7 are formed in the short surface and used for mounting the outgoing copper bars. The short sides 2 have bevels 4 on their inner edges to ensure that a sufficient electrical gap is maintained with the vertical rows 6.
In addition to the above embodiments, the present invention may have other embodiments. All technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope of the claims of the present invention.
