Description

A kind of lightning-arrest wave resistance device downlead support
Technical field
The utility model relates to shaft tower line construction technical field, is specifically related to a kind of lightning-arrest wave resistance device downlead support.
Background technology
At traditional Franklin lightning rod, owing to having the effect of good direct striking thunder prevention, also because the simple construction cost of its structure is low, and be applied in widely on the building of higher level, its principle is formed upward leader by point discharge effect and drawn to connect lightning current, and lightning current enters the earth by down conductor earial drainage the most at last.But for power high-tension transmission line, traditional Franklin lightning rod, can only be used for the shielding prevented near shaft tower, the counterattack that the shaft tower that can not prevent from being struck by lightning is formed.
Lightning-arrest wave resistance device is a kind of novel ultra-high-tension power transmission line thunder resisting equipment, be arranged on high-voltage transmission line pole tower top, form upward leader by point discharge effect and draw and connect lightning current, simultaneously, utilize the wave resistance body of its uniqueness, change the transmission characteristic of thunder and lightning, effectively reduce leading-edge steepness and the amplitude of lightning wave, realize the double effects that Lightning Shielding and the counterattack of Lightening zone near shaft tower are protected.Meanwhile, because lightning-arrest wave resistance device and tower top insulate, this special structure, will redistribute the Lightning Over-voltage of electric power line pole tower tower top, reduces the Lightning Over-voltage value of insulator further, effectively reduces the tripping rate with lightning strike of transmission line.
Be different from conventional tower top lightning rod, lightning-arrest wave resistance device is not directly enter the earth by steel tower top head tower earial drainage, but pass through an independently passage importing the earth, and require the insulation distance that down conductor and steel tower keep enough, to guarantee the reasonable distribution of thunder and lightning current potential in head of mast.Lightning-arrest wave resistance device and shaft tower insulate, and its lightning down conductor also maintains and insulate with electric power line pole tower.
In order to ensure the insulation of lightning-arrest wave resistance device lightning down conductor and shaft tower, in lightning-arrest wave resistance device system, by special insulating supporting, make the electric insulation distance that lightning down conductor and steel tower keep enough.One end of insulating rod is arranged on steel tower, and the other end is used for supporting lightning down conductor.The connection of insulating rod and shaft tower, has been come by lightning down conductor support.Conventional downlead support, is by perforate on steel tower corner iron, is connected by bolt with insulating rod termination, can cause certain damage to the structure of shaft tower, cannot change support installing position flexibly, add support installing difficulty, improve installation cost.
Utility model content
Problem to be solved in the utility model is to provide a kind of lightning-arrest wave resistance device downlead support, avoid and carry out perforate on steel tower, do not destroy former steel tower corner iron, do not affect this body structure of steel tower, can adjusting pole installation site flexibly, improve the convenience of support installing.
A kind of lightning-arrest wave resistance device downlead support, comprise steel tower corner iron and insulation support rod, described steel tower corner iron is arranged Boards wall mechanism, described Boards wall mechanism one end arranges screwed hole, described insulation support rod one end arranges set bolt, the described insulation support rod other end arranges solidus gold utensil, and described set bolt is connected with described screwed hole.
Further, described Boards wall mechanism comprise to match with described steel tower corner iron in L-type clamping plate and outer L-type clamping plate, described interior L-type clamping plate are connected by fastening bolt with described outer L-type clamping plate two ends.
Further, described outer L-type clamping plate arrange L-type support, described L-type support is arranged the retainer ring matched with described insulation support rod.
Further, described solidus gold utensil comprises hanging wire ring, and described hanging wire ring inner surface arranges elastic protective layer.
The utility model provides a kind of lightning-arrest wave resistance device downlead support, comprise steel tower corner iron and insulation support rod, described steel tower corner iron is arranged Boards wall mechanism, described Boards wall mechanism one end arranges screwed hole, described insulation support rod one end arranges set bolt, the described insulation support rod other end arranges solidus gold utensil, and described set bolt is connected with described screwed hole.Boards wall mechanism clamps steel tower corner iron, as the brace foundation of downlead support, Boards wall mechanism is wrapped steel tower corner iron by two-layer clamping plate, avoid steel tower corner iron in traditional construction and need perforated defect, and by movablely its fixed position can be set to the adjustment of Boards wall mechanism, flexible for installation.The screwed hole of Boards wall mechanism one end is connected with the set bolt of insulation support rod one end, play the fixed support effect to insulation support rod, the effect played and downlead is supported is coordinated, the simple to operate but line construction difficult problem solved in the past with the solidus gold utensil of the insulation support rod other end.
Described Boards wall mechanism comprise to match with described steel tower corner iron in L-type clamping plate and outer L-type clamping plate, described interior L-type clamping plate are connected by fastening bolt with described outer L-type clamping plate two ends.This is the one of the shape of Boards wall mechanism, specifically can for L-type clamping plate in steel tower corner iron mechanism design and outer L-type clamping plate, and two laminated plank edge correspondences arrange screwed hole, by tightened bolt presses, play the supporting role to insulation support rod.
Described outer L-type clamping plate arrange L-type support, described L-type support is arranged the retainer ring matched with described insulation support rod.Screwed hole in only dependence scheme and set bolt play the effect of fixed support to insulation support rod, at strong wind and heavy rain weather because acutely rocking of insulation support rod very easily causes the weakness of set bolt to rupture, cause damage to equipment.L-type support is arranged on outer L-type clamping plate, and the one end arranging retainer ring is connected with insulation support rod, plays fixing effect by retainer ring to insulation support rod, increases the support degree of downlead support.
Described solidus gold utensil comprises hanging wire ring, and described hanging wire ring inner surface arranges elastic protective layer.Hanging wire ring adopts steel annulus, downlead can be inserted in, more fragile in order to prevent downlead and hanging wire loop contacts from rubbing, and arranges elastic protective layer and protects.
The beneficial effects of the utility model: the utility model avoids and carry out perforate on steel tower, do not destroy former steel tower corner iron, do not affect this body structure of steel tower, can adjusting pole installation site flexibly, improve the convenience of support installing, reduce the installation cost of support, be applicable to the steel tower corner iron of various different azimuth, structure is simple, is applicable to promoting.
