Hardware fitting for cross connection of tubular bus Technical Field The utility model relates to the field of transformer substation equipment, in particular to a hardware fitting for cross connection of tubular buses. Background At present, the new energy projects develop rapidly, and large new energy projects are matched with large collecting stations, and the collecting stations are characterized in that a main transformer adopts double-loop transformer, the capacity of the low-voltage side of the main transformer is large, the current of the low-voltage side is huge, a section of bus is usually arranged on the low-voltage side of the main transformer to meet the current carrying requirement, and the bus is often a tubular bus due to the conductor current carrying capacity and the attractive field. The condition that the upper and lower dislocation and cross arrangement exists from the outlet tubular bus to the bus position of the main transformer is usually adopted, the scheme that the T-joint hardware of the integrated tubular bus is connected after the tubular bus with low cloth is bent to the bus is adopted, but due to construction errors and equipment production errors, the original integrated tubular bus T-joint hardware is easy to cause difficult installation due to height differences in the installation stage, the problem that the current-carrying capacity is influenced by the bending of the tubular bus with low cloth easily occurs after the integrated hardware is connected, the problem that the heat expansion and cold contraction stress of the tubular bus is easily transmitted to the high-cloth tubular bus through the integrated tubular bus T-joint hardware is solved, the problem that the heat expansion and cold contraction of the high-cloth tubular bus are easy to cause the deformation of the high-cloth tubular bus is solved, and the problem that the low-cloth tubular bus and a post insulator are inclined is solved. The traditional solution considers that the four-split steel-cored aluminum stranded wires are used for replacing the bending part of the tubular bus, but because the distance is short, the steel-cored aluminum stranded wires are easy to generate scattered strands, and the connecting points are more easy to generate heat.
