The utility model discloses a same surface area copper return bend flattens the both ends of copper return bend, has guaranteed that the copper return bend has greatly made things convenient for the copper return bend both ends to be connected with other products when great current-carrying capacity.
Description
Technical Field
The utility model relates to an electric power facility technical field, concretely relates to large-scale water and electricity engineering is with high reliable nanometer copper arc connecting piece.
Background
In large-scale hydroelectric engineering, large-scale copper materials are required for connection, but the cost is increased due to the high price of copper. In order to reduce the cost, according to the skin effect of current, under the condition that the cross section of a conductor is the same, the current-carrying capacity of a copper pipe is greatly higher than that of rectangular copper, but because the copper pipe is circular, the copper pipe is difficult to be connected with other products on site, under the condition that the copper pipe is longer, the connection workload is large, and if the copper pipe is required to have radian for a special structure, the connection workload is larger.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome above-mentioned not enough, provide a large-scale hydroelectric engineering is with high reliable nanometer copper arc connecting piece, adopt same surface area copper return bend, flatten the both ends of copper return bend, greatly made things convenient for copper return bend both ends and other product connections when having guaranteed that the copper return bend has great current-carrying capacity.
The purpose of the utility model is realized like this:
the utility model provides a large-scale hydroelectric engineering is with high reliable nanometer copper arc connecting piece, includes the copper return bend, the both ends of copper return bend are flattened respectively and are formed first flattening portion and second flattening portion, and the copper return bend after being flattened forms new both ends, is equipped with first changeover portion between one end and the first flattening portion, and the other end flattens and is equipped with the second changeover portion between the portion with the second.
Preferably, the first flattening portion and the second flattening portion are perpendicular to each other.
Preferably, the first and second flattened portions have a flat key-shaped cross section.
The utility model has the advantages that:
the utility model discloses a same surface area copper return bend flattens the both ends of copper return bend, has guaranteed that the copper return bend has greatly made things convenient for the copper return bend both ends to be connected with other products when great current-carrying capacity, and simple to operate is reliable, and is electrically conductive effectual.
