Description
Technical field
The utility model relates to electric armour clamp field, in particular to a kind of lightning-protection piercing grounding wire clip.
Background technology
For reducing the overhead distribution fault that the reasons such as branch, birds, accumulated snow cause, it is to increase power supply reliability. Developed country adopts suspended insulated guide wire gradually from the later stage in the 60's in the world. Insulating transformation implemented by China's urban aerial distribution network from the 80's.
The lightning-caused breaking principle of insulation wire is different from naked cable, and when attacking thunder directly or lightning induced voltage acts on insulation wire, first thunder and lightning superpotential punctures wire insulation, and then causes insulator flashover, and breakdown insulation layer is pin hole shape. Short arc current is by the obstruction of surrounding insulation frequently for continuous print, and arc root can only go out burning in vacuum, will be blown by neat at extremely short time inside conductor, thus cause the disconnection of electrical network, affect the normal operation of power transmission network.
Lightning-protection piercing grounding wire clip, for preventing a kind of insulated wire protection gold utensil of 10KV suspended insulated guide wire lightning-caused breaking and hanging earthing conductor, the broken string being struck by lightning and causing can be effectively prevented at thunderstorm season, after thunder and lightning, line insulation can be recovered, improve the reliability of circuit, and insulator is not easy to recruit broken by lightning.
At present, application number be 201220510712.4 Chinese patent disclose a kind of lightning-protection piercing grounding wire clip, it comprises penetrating cable clamp, the ground connection ring being arranged on penetrating cable clamp and the starting rod being arranged on ground connection ring, penetrating cable clamp comprises clamp base, gland and the bolt assembly for gland crimping is fixed on clamp base, clamp base upper surface is provided with clamp groove, the upper surface of described gland and lower surface are equipped with a pressuring line groove for matching with clamp groove, although this kind of lightning-protection piercing grounding wire clip can be applicable to the cable of different thicknesses, but lightning-protection piercing grounding wire clip is generally all arranged on 10KV suspended insulated guide wire for preventing thunderbolt, but at thunderstorm season, although lightning-protection piercing grounding wire clip avoids thunderbolt, but rainwater flows in penetrating cable clamp along insulated cable, water is not discharged through drainage at clamp groove, due to the characteristic that glassware for drinking water is tensioned, easily stick between clamp groove and insulated cable, form smooth water film, penetrating cable clamp is through long-time clamping, puncture part is caused corrosion by water in insulated cable, thus affect the normal use of penetrating cable clamp.

Preferably, two described radiating grooves are equipped with the deep-slotted chip breaker outstanding to pressuring line groove side on the cell wall of pressuring line groove, and by covering of gland and clamp base, two described deep-slotted chip breakers all form drainage breach on the cell wall of pressuring line groove.
Pass through technique scheme, the setting of deep-slotted chip breaker, further increases the heat dispersion of pressuring line groove, and forms drainage breach when gland and clamp base cover, facilitate rainwater when being deposited in pressuring line groove, by the pressuring line groove of arc shape, under gravity, water flows out from drainage breach along drainage trough, thus it is discharged to outside penetrating cable clamp by radiating groove, avoid water to be deposited in pressuring line groove, the part of puncture in insulation wire is caused corrosion, thus affects the result of use of penetrating cable clamp.
Preferably, described penetrating cable clamp is coated with insulating boot.
Pass through technique scheme; insulating boot is coated on penetrating cable clamp; protection penetrating cable clamp can not only be played; there is the effect of lightning protection; when being struck by lightning; thunder and lightning can not be acted directly on penetrating cable clamp by the obstruct of insulating boot, and make to act on and play lightning protection effect by penetrating cable clamp ground connection on insulated cable, and extraneous dust, rainwater also can be stoped to enter into penetrating cable clamp and cause the corrosion of penetrating cable clamp.
Preferably, described ground connection ring comprises ring body and the naked section away from penetrating cable clamp side, and described ring body is arranged with insulating sheath.
By technique scheme, insulating sheath has and cuts off the effect that thunder and lightning avoids conduction, can be used as ground connection, electrical verification when facilitating maintenance by naked section, and operation is more for convenience.
Preferably, described striking ball is coated with uncovered spherical cover.
Pass through technique scheme; when thunder and lightning occurs; discharge between striking ball and ground plate; make afterflow altogether frequently electric arc move to striking ball burn; thus protect insulation wire injury-free; not only played the effect of striking by uncovered spherical cover, and avoid completely coated spherical cover heat build-up on striking ball, play the effect of heat radiation.
