Anti-looseness sub-wire spacer for double split line

Abstract

The invention relates to an anti-looseness sub-wire spacer for a double split line, applies to a power transmission line on which a double split wire is employed in a power system and belongs to the technical field of power transmission line on-site overhaul. The anti-looseness sub-wire spacer comprises a connection rod and wire clips mounted at two ends of the connection rod. Through holes for mounting fastening bolts are arranged on the two wire clips. Nuts are mounted on the fastening bolts. Limiting pin holes are arranged at the upper ends of the fastening bolts. Pins for fastening and limiting the nuts are mounted in the limiting pin holes. A plurality of limiting grooves matching the pins are arranged on the upper surfaces of the nuts. According to the anti-looseness sub-wire spacer, the mounting is convenient, a power-cut range and the power-cut time are not increased, and the looseness of the fastening bolts is avoided.

Description

technical field [0001] The invention relates to a loose-proof sub-conductor spacer for double-split conductors, which is suitable for transmission lines using double-split conductors in power systems, and belongs to the technical field of on-site inspection and maintenance of transmission lines. Background technique [0002] The sub-conductor spacer is a commonly used power tool in the electric field. The sub-conductor spacer is composed of a support rod, a wire clamp and a fastening bolt. The working principle of the sub-conductor spacer is: the sub-conductor spacer fixes the wire through the clamp, and the Supporting function, avoiding friction or whipping of two same-phase sub-conductors to damage the conductors. [0003] Since the sub-conductor spacer is in the environment of vibration and swing for a long time, although the common sub-conductor spacer adopts the anti-loosening measures of the spring pad, it is easy to loosen in the environment of vibration and swing due...

AI Technical Summary

Problems solved by technology

[0003] Since the sub-conductor spacer is in the environment of vibration and swing for a long time, although the common sub-conductor spacer adopts the anti-loosening measures of the spring pad, due to the construction process and other reasons, it is easy to loosen in the environment of vibration and swing

Once the fastening bolts of the sub-conductor spacer are loosened, the wire clamp will be worn and broken in the early stage, and the sub-conductor spacer will fall off in the later stage and lose its supporting function
