Abstract
An auxiliary support system for use with a line-post insulator of an electric power transmission system includes a tension member of electrically insulating material coupled between a tower and the junction of a conductor support with the outboard terminus of the line-post insulator. A clamp formed of two juxtaposed jaws bends downwards to clear the conductor and support, and then bends inwardly to grip the terminus and secure it to the tension member. Attachment of the auxiliary support can be accomplished without disruption of the electric power.
Claims10
An electric power transmission system comprising:
- a tower and an electrical conductor;
- a line-post insulator extending horizontally from said tower and supporting said conductor at an outer terminus of said line-post insulator away from said tower;
- an insulating tension member extending outwardly and downwardly from said tower to meet the outer terminus of said line-post insulator;
- means for securing said conductor adjacent said outer terminus of said line-post insulator, said terminus of said line-post insulator having a generally convex surface;
- a clamp secured to said tension member, said clamp comprising:
- a first jaw and a second jaw passing between said conductor and said line-post insulator for engagement with said convex surface, said second jaw being the mirror image of said first jaw as reflected about a plane including axes of said line-post insulator and said tension member, each of said jaws having a concave arcuate gripping portion configured for mating with said convex surface of said terminus, said gripping portions of said first and said second jaws contacting said convex surface on opposite sides of said plane, each of said jaws having an arm portion curved about a line perpendicular to said plane for clearing said conductor, said arm portions extending from said gripping portions of respective ones of said jaws to a point of engagement of said clamp with said tension member;
- and
- urging means for urging said jaws together for secure engagement of said gripping portions of said jaws with said outer terminus of said line-post insulator.
In an electric power transmission system comprising:
- a tower and an electrical conductor;
- a line-post insulator extending horizontally from said tower and supporting said conductor at an outer terminus of said line-post insulator away from said tower;
- a method of securing said outer terminus of said line-post insulator to said tower during a state of power flow through said conductor comprising:
- extending an electrically-insulating tension member from said tower to said terminus;
- securing a clamp to an outer end of said tension member, said clamp comprising a pair of opposed jaws, each of said jaws including an arm portion extending toward said tension member;
- positioning said clamp between said conductor and said terminus, said positioning including a spacing of said jaws on opposite sides of said insulator at said terminus;
- and
- urging said jaws together while orienting a bend in each of said arm portions of said jaws for providing clearance of said conductor and connection of said tension member with said terminus.
A clamp for securing the outer end of a horizontal line-post insulator of an electric power transmission system comprising:
- a first jaw and a second jaw, said second jaw being the mirror image of said first jaw as reflected about a central plane of said clamp, each of said jaws having a concave arcuate gripping portion configured for mating with a convex surface of an outer end of said line-post insulator, the concave portions of each of said jaws facing said central plane to permit said first jaw and said second jaw to contact opposite sides of the outer end of said line-post insulator, each of said jaws having an arm portion curved about a line perpendicular to said plane to provide clearance of an electrical conductor at the outer end of said line-post insulator, said arm portions extending from said gripping portions of respective ones of said jaws to permit engagement with a tension member of a power transmission system;
- and
- urging means for urging the arm portions of said first and said second jaws toward each other to permit secure engagement of said gripping portions of said jaws with said outer end of said line-post insulator.
A clamp for engagement with the outer end of a horizontal line-post insulator in an electric power transmission system wherein a tension member extends between a tower of the system and the outer end of the line-post insulator, the clamp comprising:
- a first jaw and a second jaw arranged in opposed configuration, one of said jaws being the mirror image of the other of said jaws, each of said jaws having gripping portions configured for enclosing a portion of an outer perimeter of an outer end of said line-post insulator;
- first and second arms extending from said first and said second jaws, each of said arms having end fittings to permit engagement with a tension member of a power transmission system, each of said arms being configured for closure towards each other in juxtaposed relation;
- and
- means coupling said first arm with said second arm for retaining said first arm and said second arm in said juxtaposed relation as said first and said second jaws extend respectively from said first arm and said second arm to permit a holding of said line-post insulator.
