Adjustable tubular bus fitting

Abstract

The invention discloses an adjustable tubular bus fitting, and belongs to the technical field of tubular bus connection. The adjustable tubular bus fitting comprises a tubular busbar clamp, a guide rod, an expansion joint and an aluminum section, wherein an upper tubular busbar and a lower tubular busbar are connected by the tubular busbar clamp and the expansion joint; the two ends of the aluminum section are respectively connected with one side of the expansion joint; the two ends of the guide rod are respectively connected with the other side of the expansion joint; the tubular busbar clamp comprises an upper tubular busbar clamp and a lower tubular busbar clamp, wherein the upper tubular busbar clamp clamps the upper tubular busbar, the upper tubular busbar is provided with an upper cover plate, and the upper cover plate is connected with the upper tubular busbar clamp through a bolt; the lower tubular busbar clamp clamps the lower tubular busbar, the lower tubular busbar is provided with a lower cover plate and the lower cover plate is connected with the lower tubular busbar clamp through a bolt; the adjustable tubular bus fitting further comprises an upper clamping plate and a lower clamping plate; the lower end of the upper tubular busbar clamp is provided with the upper clamping plate; the upper end of the lower tubular busbar clamp is provided with the lower clamping plate; the upper tubular busbar clamp, the upper clamping plate, the lower tubular busbar clamp and the lower clamping plate are one-time molded by casting by using aluminum alloys; and the mounting distance can be adjusted without field setting-out and processing.

Description

technical field [0001] The invention relates to the technical field of pipe-female connection, in particular to an adjustable pipe-female fitting. Background technique [0002] Pipe bus is mainly used in the conductor connection between the power grid transmission wire and the substation transformer in my country's electric power construction projects, the jumper in the transmission line, the connecting conductor in the power equipment, and the overcurrent conductor in the high-current DC ice-melting device. The new conductors of traditional rectangular, slotted, rod-shaped busbars and flexible wires are one of the key equipment or materials in power transmission and transformation systems, and play a vital role in the safe and reliable operation of power transmission and transformation systems and power equipment role. The installation distance cannot be adjusted when the traditional pipe-female fittings are connected, and the lofting process must be carried out according to...
