Description
Technical field
This utility model relates to a kind of insulator, particularly relates to a kind of anti-Broken of Overhead Insulation Lines By Lightning insulator.
Background technology
Suspended insulated guide wire is a kind of Novel wire grown up in 10 kV distribution network constructions in recent years, have many advantages compared with common overhead bare conductor, common overhead bare conductor can be solved be in operation the difficult problem run into, and price is far below power cable, therefore, in 10 kV distribution network constructions progressively selected by people.
After suspended insulated guide wire circuit is struck by lightning, direct lightning strike or lightning induced voltage act on wire, cause the position of insulated conductor breakage to have focused largely on straight line pole the load side away from support insulator fixing point about 200mm；
Straight line pole supports the support insulator of suspended insulated guide wire, and the mode of fixing wire is divided into binding-type and bolt compression joint type；Due to binding-type or bolt compression joint type fixed insulation wire, binding wire or impacted bolt constitute the floating potential annular that has of a ring wire and close conductor and wire insulation, when thunder and lightning hits insulated conductor, insulated conductor overvoltage, wire changes at electric field at annular Guan Bi conductor, causes wire to fuse in the load side away from insulator fixing point about 200mm.
Utility model content
For achieving the above object, the technical solution adopted in the utility model is: a kind of anti-Broken of Overhead Insulation Lines By Lightning insulator, including support insulator, it is characterized in that: described support insulator upper end is designed with wire clamp, wire clamp includes wire clamp seat, wire clamp seat upward opening, it is designed with taper groove in wire clamp seat, wire clamp seat innermost insert has nylon compound bar and nylon to be combined voussoir, it is corresponding with described taper groove that nylon is combined voussoir, wire clamp seat bottom is designed with screw, screw female thread connects bolt, the end of bolt is with pad, the big end that pad is combined voussoir with described nylon is corresponding.
In this structure, described wire clamp seat is C-shaped wire clamp seat.
In this structure, the opening part both sides of described wire clamp seat are respectively designed with long baffle plate and short shutter, and it is corresponding that described long baffle plate is combined voussoir with described nylon, and described short shutter is corresponding with described nylon compound bar.
In this structure, the inner side of described nylon compound bar is designed with the first arc groove, and described nylon is combined the inner side of voussoir, and to be designed with the second arc groove, the first arc groove and the second arc groove corresponding.
The utility model has the advantages of and be: due to this structure of the present utility model, so being avoided that the galvanic circle forming Guan Bi when using this practicality, avoid when being struck by lightning, insulator top does not haves induced overvoltage, the electric current occurred because of lightning current and voltage, and fastening a bolt can be by conductor compression jointing on the top of insulator, easy for installation, conductor compression jointing is firm.
