An optimization method for the installation of gapped conductor balance hanging wire

Abstract

The invention discloses a method for optimizing the installation of intermittent wire balance hanging wires, which includes the following steps: S1. Construction preparation: determining the length of the replacement wire segment, the number and type of iron towers in the interval of the replacement wire segment, calculating the tension of the ground wire, and installing accessories. Wire force; determine the wire hanging scheme, wire lifting scheme, and the type and specification of installation construction tools; S2, installation of construction tools; S3, wire hanging and pressing operations; S4, tightening operations; S5, marking and crimping operations; replacement There are N tension towers in the section of the wire segment, and a straight tower is arranged in the middle of each adjacent tension tower, where N is an odd number. The program adopts changing the operation sequence and tightening method to greatly reduce the workload and shorten the construction period. The aluminum layer and the steel core are crimped into a whole by using the special traction head of the gap type wire, and then the wire is directly tightened on the ground and marked at high altitude through the wire pulley. , crimping to reduce labor, improve efficiency, and reduce labor intensity.

Description

technical field [0001] The invention relates to the field of construction technology of power transmission and transformation power lines, and in particular relates to an optimization method for installation of gapped wire balance hanging wires. Background technique [0002] With the rapid development of social economy, the transmission capacity of the original transmission line cannot meet the needs of current economic development, and the new line faces problems such as land requisition, high cost investment, and long construction period. The use of gap-type conductors can use the iron tower of the original line Only need to replace the suspension clamps and tension clamps, its low sag characteristics (both aluminum wire and steel core are made of heat-resistant materials) can avoid the safety distance between the wires and the ground and the crossing objects caused by the insufficient height of the original tower, The normal operating temperature of the wire can be greatl...
