Abstract
The invention discloses a GIL (gas insulated high voltage transmission line) transition section conductor connecting structure, which comprises a base, a shielding case, a conductor and a plum-blossom contact assembly. The plum-blossom contact assembly comprises a plurality of groups of contact fingers, a guide sheet, a fixed stop guide plate and fastening springs. Each group of contact fingers consists of a main contact finger, an auxiliary contact finger and a pressing and fixing piece. The fixed stop guide plate is fixedly arranged on the base through a guide rod. The conductor is inserted into the plum-blossom contact assembly. Each main contact finger is inserted into the fixed stop guide plate and the guide sheet from bottom to top and is pressed and fixed with the base and the conductor through the fastening springs. Each auxiliary contact finger is rotatably and fixedly arranged on the corresponding main contact finger through the pressing and fixing piece and is pressed and fixed with the conductor through the fastening springs. The GIL transition section conductor connecting structure can nicely realize the permanent and tight pressing contact between the contact fingers and the conductor and ensure the operating safety of equipment.
