Method for shearing and reconnecting 10kV overhead bare conductor on load

Abstract

The invention relates to a method for on-load shearing and reconnecting a 10kV overhead bare conductor, which comprises the following steps: S1, hanging a conductor clamping device, a tension traction conversion tool, a backup protection conductor clamping device and an insulating rope, S2, installing an insulating drainage wire, S3, measuring current, S4, cutting off the conductor and connecting and pressing the conductors on two sides by using a conductor connecting fitting, S5, measuring current, S6, cutting off the conductor, and S5, reconnecting the conductor. S6, the tension traction conversion tool and the wire clamping device are dismantled; the tension traction conversion tool has the advantages that when the wire is cut off and the wire connection fitting is used for connecting and pressing the wires on the two sides, the insulation drainage wire is mounted on the tension traction conversion tool, so that the current of the wire can be shunted to the insulation drainage wire, and after the wire connection fitting is connected and pressed with the wires on the two sides, the current circulation can be realized through the wire connection fitting; therefore, reconnection of the overhead bare conductor can be realized in an on-load state, power failure of a user is avoided, the conductor operates in an on-load manner in the whole process, power utilization of any user is not affected, and power utilization stability is guaranteed.

Description

technical field [0001] The invention relates to a method for cutting and reconnecting 10kV overhead bare conductors with load. Background technique [0002] The 10kV overhead line will cause wear and damage to the 10kV overhead bare wire when crossing the road with taller vehicles passing by or trees touching the wire for a long time, affecting the mechanical properties of the wire, and in severe cases, it will cause the wire to break and pull. According to the relevant regulations of the 10kV distribution network live work regulations, the damaged wire should be cut and reconnected in the following three situations: the damage area of ​​the aluminum strand of the same section of the steel cored aluminum strand conductor exceeds 25% of the aluminum area; the damage of the aluminum strand of the same section of the single metal wire The area exceeds 17% of the aluminum area; although the continuous damage of the wire is within the allowable repair range, the length of the dam...
