Remote manipulator for manipulating live multiple sub-conductors in a single phase bundle
A manipulator for separating sub-conductors in an energized single phase bundle includes a rigid support member and first and second actuators mounted on the support member, wherein each actuator is independently actuable of the other. Insulators are mounted on each actuator. A selectively releasable coupler is mounted on each insulator for selectively releasable coupling of each insulator to a corresponding sub-conductor. The actuators extend corresponding insulators independently of one another from the support member to thereby separate from each other by an optimized separation distance the distal ends of each insulator. When the corresponding sub-conductors of the single phase bundle are releasably coupled to the corresponding distal ends of the insulators the surge impedance loading of the single phase bundle may be improved by separation of the corresponding distal ends of the insulators and the sub-conductors by the optimized separation distance.
1. A method for separating multiple sub-conductors in a live single phase bundle, comprising the steps of:
providing a rigid support member mountable on the end of a boom
providing at least first and second actuators mounted on said support member, wherein each actuator of said at least first and second actuators is independently actuable,
providing an insulator mounted on said each actuator of said at least first and second actuators and a selectively releasable coupler mounted on each said insulator for selectively releasable coupling of said each insulator to a corresponding sub-conductor in an energized single phase bundle of sub-conductors, wherein said each insulator has a distal end,
arranging said at least first and second actuators and actuating by actuation means said at least first and second actuators so as to extend corresponding said insulators independently of one another from said support member,
releasably coupling to the distal ends of said each insulator the corresponding sub-conductors of the energized single phase bundle,
increasing the surge impedance loading of the single phase bundle by separating from each other by an optimized separation distance said distal ends of said each insulator.
2. The method of claim 1 further comprising the steps of:
providing that said each actuator actuates a corresponding said each insulator linearly along a linear actuation trajectory and that said actuation trajectories for said each actuator are parallel.
3. The method of claim 2 further comprising the steps of providing a common base and that said each actuator is mounted on said common base and said base is mounted on said support member and providing that said base is selectively pivotally mounted on said support member and providing a selectively actuable pivoting means for pivoting said base support member.
4. The method of claim 3 further comprising the steps of orienting said each actuator so that said actuation trajectories extend upwardly from said support and said base, wherein said optimized separation distance is a substantially vertical spacing between the corresponding separated sub-conductors.
5. The method of claim 3 further comprising the steps of orienting said each actuator so that said actuation trajectories extend downwardly from said support and said base, wherein said optimized separation distance is a substantially vertical spacing between the corresponding separated sub-conductors.
6. The method of claim 3 wherein each of said actuators has a distal end, said method further comprising the steps of laterally spacing said actuators along said base so that the lateral spacing between the distal ends of said actuators is substantially equal to lateral spacing between the corresponding sub-conductors in the single phase bundle.
7. The method of claim 3 further comprising the steps of extending said actuation trajectories substantially horizontally from said base so that said optimized separation distance is a substantially lateral spacing between the corresponding separated sub-conductors in the single phase bundle.
