Technical Field

The invention relates to the technical field of wire repair, in particular to a wire repair device for a 220KV power transmission line.

Background

High voltage line generally refers to a transmission line carrying voltages above 10 kV. High pressures are generally free of 1000V, as specified in GB/T2900.50-2008, definition 2.1. The voltage grades of the high-voltage transmission lines in China are generally divided into: 35kV, 110kV, 220kV, 330kV, 500kV, 750kV and the like. Wherein 110kV and 330kV are mostly used in northern areas. Generally, transmission voltages of 220kv or less are called high-voltage transmission, transmission voltages of 330 to 750kv are called ultra-high-voltage transmission, and transmission voltages of 1000 kv or more are called ultra-high-voltage transmission. High-voltage transmission is generally transmitted underground by cables with insulating layers in cities, and is transmitted by overhead lines carried by iron towers in the field.

The steel-cored aluminum conductor is a mainstream conductor which is used in a large amount in a distribution network 220kV line, has a series of advantages of high tensile strength, good lightning protection performance, low manufacturing cost and the like, and is widely applied to suburb joints and rural network lines. However, once the steel core aluminum conductor line is damaged by external force or affected by bad weather, the mixed connection short circuit fault of the conductor is very easy to occur, and the strand breaking phenomenon of the conductor can occur after the mixed connection short circuit occurs. The wire repair method has the advantages that proper wire repair treatment is required in time, the mechanical performance and the conductivity of the wire are prevented from being reduced due to the continuation of strand scattering, the wire is repaired by the pre-twisted wire, the covering strength loss of the wire does not exceed 5% of the total breaking force, the cross section damage of the wire does not exceed 7% of the total cross section of the conductive part, the pre-twisted wire is used for connecting hardware fittings of overhead power wires, overhead power cable terminals, suspensions, joints and the like, and the pre-twisted wire hardware fitting is widely applied to the fields of power transmission and distribution, optical fiber communication, electrified railways, cable televisions, buildings, agriculture and the like.

The repair for the 220KV transmission line conductor in the prior art publication generally adopts the preformed armor rods for repair, generally adopts manual winding, wastes time and labor in winding and has low efficiency, and the stress at two ends of the manually operated conductor is uneven, so that the repair using effect is not good enough.
