Abstract
The utility model discloses a triangular connecting plate connector used for a double bundled conductor in a power transmission line. The triangular connecting plate connector comprises a U-shaped plate supporting rack which has double structures with a certain distance. The bottom of the U-shaped plate supporting rack is a planar structure. A connecting block is disposed on the lower part of the planar structure and connects the double structures by using bolts on the lower part of the planar structure. A left side plate and a right side plate are disposed on the two sides of each top of the U-shaped plate supporting rack and are arranged in parallel. Screw holes are correspondingly disposed on the left side plate and the right side plate. A Bolt passes through the bolt holes on the left side plate and right side plate and is fixed by a screw nut. The distance between the left side plate and the right side plate is more than the thickness of the insulating pulling plate of a triangular connecting plate lifting device. The left side plate, the right side plate, and the triangular connecting plate lifting device are fixed together by a screw nut and a bolt. The triangular connecting plate connector is capable of maintaining a line insulator at a loose state so as to easily overhaul or replace an insulator chain and is capable of achieving a purpose of overhauling or replacing the line insulator by using power-on indirect operation.
