Abstract
The utility model discloses a lightning-protection piercing grounding wire clip, which comprises a piercing wire clip body, a capping, a screw assembly used for fixing the capping on the piercing wire clip body, a square framework being fixed at the bottom of the piercing wire clip body, an arc striking rod at one corner of the bottom of the square framework and extending toward the outer side of the framework, and an arc striking ball arranged at the end of the arc striking rod. The lightning-protection piercing grounding wire clip has the advantages of relatively reasonable structure and good lightning protection effect.
Description
Technical field
The utility model belongs to the electric armour clamp technical field, is specifically related to a kind of lightning protection puncture earthing clamp.
Background technology
For reducing the overhead distribution fault that reasons such as branch, birds, accumulated snow cause, improve power supply reliability.Developed country gradually adopts suspended insulated guide wire from the later stage in the sixties in the world.China begins city overhead distribution net from the eighties and implements the insulating transformation.
Insulated conductor has solved corridor and safety problem that plain conductor can't resolve really, compares with cable, reduced investment, builds soon, and advantage is obvious, but the lightning-caused breaking problem is very outstanding.
The lightning-caused breaking principle of insulated conductor is different with plain conductor, and when direct lightning strike or lightning induced voltage acted on insulated conductor, lightning overvoltage at first punctured wire insulation, and then causes insulator arc-over, and breakdown insulating barrier is the pin hole shape.The short arc current of continuous frequency is subjected to the obstruction that insulate on every side, and the arc root can only be in the burning of pin hole place, will be at extremely short time inside conductor by neat blowing, thus cause the disconnection of electrical network, influence the operate as normal of power transmission network.
Therefore, the lightning protection gold utensil is installed in the anti-lightning strike broken string measure of extensively adopting both at home and abroad exactly additional on insulated conductor.But the structure of existing lightning protection penetrating cable clamp is not satisfactory, remains and is needing improvements badly.
Summary of the invention
The purpose of this utility model provides the lightning protection puncture earthing clamp that a kind of structure is comparatively reasonable, have better lightning protection effect.
The technical scheme that realizes the utility model purpose is: comprise penetrating cable clamp body, gland and be used for gland is fixed on screw arbor assembly on the penetrating cable clamp body; Its design feature is: also comprise the quadra that is fixed on penetrating cable clamp body bottom, one jiao of place is provided with the starting rod that extends towards the framework outside in described quadra bottom, is provided with the striking ball at the end of starting rod.
In the such scheme, described starting rod is along extending with the cornerwise direction of this place, angle quadra.
In the such scheme, described quadra is arranged with the silicon rubber insulation sheath outward, and the middle body of described quadra base framework is exposed in the atmosphere.
In the such scheme, described starting rod is arranged with the silicon rubber insulation sheath outward, and described striking ball is exposed in the atmosphere.
In the such scheme, described screw arbor assembly comprises torque nut.
The utlity model has positive effect: (1) the utility model is provided with quadra, starting rod and striking ball in the penetrating cable clamp bottom; when thunder and lightning takes place; discharge between striking Metal Ball and the ground plate; the afterflow power frequency arc is moved on the striking Metal Ball burn, thereby the protection insulated conductor is injury-free.
(2) in the utility model, described quadra is arranged with the silicon rubber insulation sheath outward, and the middle body of described quadra base framework is exposed in the atmosphere.Insulating sleeve adopts silicon rubber to make, and has good insulation performance performance, ageing resistace and fire resistance, and it is assemblied in the outside of quadra, can play the insulation protection effect.The middle body of quadra base framework is the position that exposes, and can be used as the usefulness of ground connection, electrical verification when maintenance.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Be labeled as shown in the accompanying drawing: penetrating cable clamp body 1, gland 2, screw arbor assembly 3, torque nut 31, quadra 4, the middle body 41 of quadra base framework, starting rod 5, striking ball 6, silicon rubber insulation sheath 7.
Embodiment
(embodiment 1)
Fig. 1 is a kind of structural representation of the present utility model, has shown a kind of embodiment of the present utility model.Present embodiment be a kind of when power circuitry engineering is constructed used lightning protection puncture earthing clamp, see Fig. 1, comprise penetrating cable clamp body 1, gland 2 and be used for gland 2 is fixed on screw arbor assembly 3 on the penetrating cable clamp body 1; It is characterized in that: also comprise the quadra 4 that is fixed on penetrating cable clamp body 1 bottom, one jiao of place is provided with the starting rod 5 that extends towards framework 4 outsides in described quadra 4 bottoms, is provided with striking ball 6 at the end of starting rod 5.

Be arranged with silicon rubber insulation sheath 7 outside the described quadra 4, and the middle body 41 of described quadra 4 base frameworks is exposed in the atmosphere.
Be arranged with silicon rubber insulation sheath 7 outside the described starting rod 5, described striking ball 6 is exposed in the atmosphere.
Described screw arbor assembly 3 comprises torque nut 31.
The utlity model has positive effect:
(1) present embodiment is provided with quadra, starting rod and striking ball in the penetrating cable clamp bottom, when thunder and lightning takes place, discharges between striking Metal Ball and the ground plate, the afterflow power frequency arc is moved on the striking Metal Ball burn, thereby the protection insulated conductor is injury-free.
(2) in the present embodiment, be arranged with silicon rubber insulation sheath 7 outside the described quadra 4, and the middle body 41 of described quadra 4 base frameworks is exposed in the atmosphere.Insulating sleeve adopts silicon rubber to make, and has good insulation performance performance, ageing resistace and fire resistance, and it is assemblied in the outside of quadra, can play the insulation protection effect.The middle body of quadra 4 base frameworks is the positions that expose, and can be used as the usefulness of ground connection, electrical verification when maintenance.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all execution modes.And these belong to conspicuous variation or the change that connotation of the present utility model extends out and still belong to protection range of the present utility model.
