Abstract
The utility model discloses a lightning puncture-prevention wire clip which comprises an upper cover and a base provided with a wire holding chase and convex thorns. Through holes are formed on the base and the upper cover on two sides of a wiring groove, and screw rod components used for fixedly connecting the base and the upper cover are arranged in the through holes; a main arc striking rod extending aslant downwards is arranged at one end of the bottom of the base and faces to the outer side of the end, and an auxiliary arc striking rod extending aslant downwards is arranged at the other end of that and faces to the outer side of the end; and an arc striking ball is arranged at the tail end of the main arc striking rod. The wire clip is matched with an external ground plate for use, and an external ground rod points to the arc striking ball on the main arc striking rod in the wire clip. In case of thunder and lightning, electricity is discharged between the metal arc striking ball and the ground plate and the afterflow power frequency arc moves to the metal arc striking ball to burn, so as to protect an insulated conductor positioned in the wire holding chase from damage.
Description
Technical field
The utility model belongs to the electric armour clamp technical field, is specifically related to a kind of lightning protection penetrating cable clamp.
Background technology
The skyborne insulated conductor of frame is easy to because of thunderbolt causes broken string at thunderstorm weather, so the lightning protection of suspended insulated guide wire is the important topic of electric utility with protection always.Taking precautions against suspended insulated guide wire is exactly with near the local bare wireization of the insulated conductor the insulator by the main method of lightning-caused breaking, make power frequency arc arc root shift or be fixed on the special gold utensil and burn, thereby guardwire avoids burn.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 penetrating cable clamp that a kind of structure is comparatively reasonable, have better lightning protection effect.
The technical scheme that realizes the utility model purpose is: a kind of lightning protection penetrating cable clamp, comprise the base and the loam cake that are provided with clamp groove and protruding thorn, described base and loam cake respectively are provided with an open-work in the both sides of connecting groove, are provided with in described each open-work to be used for screw arbor assembly that base is fixedlyed connected with loam cake; One end of described base bottom is provided with towards this end lateral direction and is tilted to down the main starting rod that extends, and the other end is provided with towards this end lateral direction and is tilted to down the secondary starting rod that extends, and the end of described main starting rod is provided with the striking ball.
In the technique scheme, described screw arbor assembly comprises a torque nut and a screw rod.
In the technique scheme, be provided with the insulating case that is used for being enclosed within on the screw arbor assembly screw rod outer wall in described each open-work.
In the technique scheme, described going up on the lid top wall is arranged with the silicon rubber insulation protective sleeve, and described protective sleeve is provided with the protective trough that is used to be enclosed within on the external cable.
The utlity model has positive effect: (1) the utility model in use; need with the supporting use of external ground plate; striking ball on the main starting rod in described external earth rod sensing the utility model; 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, injury-free thereby protection is arranged in the insulated conductor of clamp groove.In addition, the utility model adopts piercing to continue, and installation is convenient, alleviates labor intensity of operating personnel.Clamp nut adopts the aluminium alloy torque nut, and thrust is constant, avoids twisted wire impaired, and installation quality is more reliable and more stable.
