Description

Auxiliary jig for installing double-bundle sub-conductor spacer
Technical Field
The invention belongs to the technical field of power transmission protection, and particularly relates to an auxiliary jig for installing a double-split sub-conductor spacer.
Background
With the continuous development and expansion of the scale of the power grid, the power transmission line generally adopts double split conductors in order to inhibit corona discharge and reduce line impedance. On the horizontally arranged double split conductors, in order to prevent the sub-conductors in the span from colliding and rubbing with each other and from twisting together under the action of wind, a sub-conductor spacer is required to be additionally arranged between the two sub-conductors so as to limit the relative movement between the sub-conductors and ensure the parallel state of the sub-conductors under the condition of normal operation. However, the overhead line is exposed in the natural environment for a long time and is affected by factors such as wire vibration, wind, sunlight, rain and snow erosion, or the installation of the spacer itself is not standard enough, so that the conditions such as corrosion, abrasion, looseness and even fracture are easy to occur, and the conditions seriously threaten the safe and stable operation of the power transmission line, so that the line spacer needs to be comprehensively checked and the damaged spacer needs to be replaced in time during each maintenance.
The conductor spacer of installation includes the fixing device at shaft and shaft both ends at present, and the work operation mode of repacking, change sub-conductor spacer has two kinds: equipotential elimination and power failure elimination. Equipotential disappears and lacks, means that under the normal electrified condition of circuit, the operating personnel climbs insulating rope ladder and carries out artifical installation, and the son wire down can the bearing push down because of people's gravity influence for two wire interval grow, cause the installation difficulty. The power failure defect elimination is that when a circuit has a power failure, an operator drives the spacer to install the spacer by means of a flying vehicle, and pulls the upper sub-conductor by means of the protection rope until the distance between the two sub-conductors meets the requirement, and then the spacer is installed.
The installation mode of above-mentioned two kinds of circumstances all has very big potential safety hazard to hardly adjust the interval of two sub-wires to the standard distance through manual mode, greatly reduced the efficiency of conductor spacer installation.
