Abstract

In order to solve the defect that exists among the prior art, the utility model particularly designs a two -way lightning protection fastener, including the fastener body, be provided with gland and bits on the fastener body, the bits inside lining is on the gland, and the design has saucer -type spring on the gland, and gland, bits and butterfly type spring pass through the moment nut and the screw rod connection is fixed, gland, bits and butterfly type spring fixed connection structure are equipped with the sheath outward, it has starting rod sheath integrated configuration still to design on the fastener body, a discharge gap ball is established to fastener body lower extreme, and discharge gap ball both sides are respectively established one and are led the arc foot, leads the terminal ball -type structural design of being of arc foot.

Description

Bidirectional lightning protection wire clamp

Technical field

The utility model relates to technical field of electricity, particularly relates to a kind of Bidirectional lightning protection wire clamp.

Background technology

Isolation power-frequency voltage in air gap during normal operating voltage, lightning arrester body does not bear voltage; Under the lightning overvoltage effect that induced lightening or direct lightning strike produce, air gap is breakdown, and penetrating electrodes is to the electric discharge of lightning arrester body top, and high voltage piercing electrode makes insulated conductor local exposed and there is the problem of insulation defect; Unidirectional striking in the ordinary course of things, discharging gap ball can tolerate about 5 times, durable not.

Summary of the invention

In order to solve the defect existed in prior art, the utility model devises a kind of Bidirectional lightning protection wire clamp especially, and this product can well overcome the defect existed in prior art.

The technical scheme that the utility model adopts is as follows:

Bidirectional lightning protection wire clamp, comprise wire clip body, described wire clip body is provided with gland and gear piece, gear piece liner is on gland, gland is designed with disk spring, gland, gear piece and butterfly spring are connected and fixed by torque nut and screw rod, be provided with sheath, described wire clip body is also designed with starting rod protecting cover combined structure outside described gland, gear piece and butterfly spring fixed connection structure; A discharging gap ball is established in wire clip body lower end, and discharging gap ball both sides respectively establish one to lead arc pin, leads arc pin end for ball shape structure to design.

The beneficial effects of the utility model are the pointed tooths by adopting said structure design to add some on gear piece, under pressure, pointed tooth punctures wire insulation and core close contact, contact resistance value between the two is little, due to pointed tooth squeezed tight insulating barrier, need not additionally consider wire sealing problem; Add insulating case overwrap designs, the problem that there is insulation defect because installation high-voltage penetrating electrodes makes insulated conductor local exposed can well be solved; Prior art is generally unidirectional striking, gap ball can tolerate burning of about 5 times power frequency heavy-current electric arcs, now change two-way preventing arc corner structure into, decrease the degree that gap ball burns out, thus extend the life-span of gap ball, simultaneously because adopt ball-type discharge mode, rescinded angle radius is large, electric field is more even, and the possibility that therefore corona discharge occurs in atmosphere is less, and stability is higher.
