technical field

The utility model belongs to the technical field of power transmission and distribution, and in particular relates to a joint structure of a tubular busway conductor.

Background technique

The conductors of tubular bus ducts mainly use tubular conductors as the transmission medium of electric energy, and the connection between tubular bus ducts has become an urgent problem to be solved. At present, most of the busway products are mainly rectangular conductors. The connection problem between the conductors can be solved by plane contact. The tubular conductors are all curved surfaces. If the curved surface contact method is used, the contact surface is likely to be incomplete. If the contact pressure is small, the contact resistance of the final joint will increase, and the heat of the joint will be too large, so that the joint will be burned.

Screw holes are set on the middle plane.

Further, a chamfer is provided at the connection between the pipeline connection end and the pipeline conductor.
