Abstract
The utility model provides a multi-function interval discharge wire clamp for a distribution network tower insulation cross arm. The multi-function interval discharge wire clamp includes an upper metal plate, a middle metal plate and a lower metal plate. Through bolt holes are disposed at two ends of the three combined metal plates and are equipped with fastening bolts and nuts for fastening the upper metal plate, the middle metal plate, the insulation cross arm, the lower metal plate into an integral whole. The middle part of the combined metal plates by the upper and middle metal plates is provided with a through groove for wire fixing. The upper half of the through groove is disposed on the upper metal plate, and the lower half of the through groove is disposed on the middle metal plate. The through groove makes contact with an exposed core of the wire via a cavity wall of the upper and lower half of the through groove to fix the wire. Or, metal tines of the cavity wall of the upper and lower half of the through groove are used for puncturing the wire sheath so that the through groove makes contact with the wire to fix the wire. The lower metal plate is a tower insulation cross arm supporting plate, and a metal interval discharge rod is disposed at the bottom of the lower metal plate. The multi-function interval discharge wire clamp has advantages of achieving three functions of wire fastening, line broken protection and interval discharge lightning protection, effectively protecting a tower transmission line from breakdown and flashover by lightning stoke and preventing tripping due to lightning stoke.
