Description
Technical field
The present invention relates to a kind of insulator, particularly relate 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 10kV distribution network construction 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 10kV distribution network construction 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 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, changing through annular Guan Bi conductor place electric field, causes wire to fuse in the load side from insulator fixing point about 200mm.
For achieving the above object, the technical solution used in the present invention is: a kind of anti-Broken of Overhead Insulation Lines By Lightning insulator, including support insulator, it is characterized in that: the design of described support insulator upper end has wire clamp, wire clamp includes wire clamp seat, wire clamp seat upward opening, tapered groove is designed in wire clamp seat, wire clamp seat innermost insert has nylon compound bar and nylon compound voussoir, nylon compound voussoir is corresponding with described taper groove, the design of wire clamp seat bottom has screw, screw female thread is connected to bolt, the end of bolt is with pad, pad is corresponding with the big end of described nylon compound voussoir.
In this structure, described wire clamp seat is C shape 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 described long baffle plate is corresponding with described nylon compound voussoir, and described short shutter is corresponding with described nylon compound bar.
In this structure, the inner side design of described nylon compound bar has the first arc groove, and the inner side design of described nylon compound voussoir has the second arc groove, and the first arc groove and the second arc groove are corresponding.
Advantages of the present invention effect is in that: due to this structure of the present invention, so being avoided that the galvanic circle forming Guan Bi when using this practicality, avoid when being struck by lightning, insulator top does not have the induced overvoltage, the electric current that occur because of lightning current and voltage, and fastening a bolt can by the conductor compression jointing top at insulator, easy for installation, conductor compression jointing is firm.
