Copper-aluminum transition connecting piece for fixing transformer pile head and aluminum conductor
2014
The invention relates to a copper-aluminum transition connecting piece for fixing a transformer pile head and an aluminum conductor. Compared with the prior art, the copper-aluminum transition connecting piece overcomes the defect that a copper-aluminum transition connecting piece applicable to pile heads with various specifications does not exist. The copper-aluminum transition connecting piece further comprises a copper sheet (3) and an aluminum sheet (4). The copper sheet (3) and the aluminum sheet (4) are welded together horizontally. An aluminum wire fixing support (5) is fixedly arranged on the aluminum sheet (4). The aluminum wire fixing support (5) is provided with aluminum wire supports (6). The aluminum wire supports (6) are provided with aluminum wire mounting bases (7). A reinforcing copper plate (8) is located on the copper sheet (3) and the aluminum sheet (4) and fixedly arranged on the aluminum sheet (4) through a bolt (10). The reinforcing copper plate (8) and the copper sheet (3) are jointly provided with a pile head mounting hole (9). The reinforcing copper plate (8) and the copper sheet (3) are arranged on a pile head (2) through the pile head mounting hole (9). The copper-aluminum transition connecting piece is applicable to the pile heads with any specification and can be connected with multiple aluminum wires.
