Abstract
The invention relates to an overhead wire fixing device, which comprises an angular lower base plate composed of two semi-rings, an upper press plate, and bolts, wherein the two ends of each semi-ring are respectively provided with a projecting lug, a bolt hole for connecting the bolt is provided on each projecting lug, and the two ends of the upper press plate are respectively provided with a through-hole corresponding to the bolt hole on the projecting lug of the semi-ring and passing through the bolt. By using the device, the overhead wire can be directly and conveniently fixed on the insulator, instead of the original fixation mode by a metal binding wire. The inventive device has the advantages of simple installation, low labor intensity, exemption from inspection and maintenance during operation, excellent burn-out proof performance, safe operation, and high reliability; and is suitable for being used on the copper and aluminum overhead wire with 10 KV.
Description
Technical field
The present invention relates to be used for the fixing device for air lead of electric power system overhead distribution, belong to power distribution network technology field.
Background technology
Generally all adopting metal bundle silk to carry out colligation between the lead of 10kV overhead distribution and the insulator fixes.It has three big shortcomings: (1) troublesome poeration, and labor strength is big; (2) colligation intensity is low, and each workman's colligation quality degree difference is very big; (3) poor stability.In case take place between lead and the earth between single-phase short circuit or lead and the lead phase fault to take place, electric arc probably blows metal pricks silk, thereby being in, lead do not have and the fixing unsafe condition of insulator, safe operation to system constitutes grave danger, and the situation that metal bundle silk is blown is not easy to be found toward contact.How to improve the lead of 10kV overhead distribution and the fixed mode between the insulator, it is the problem that extremely presses for solution in the distribution network system.
Summary of the invention
The objective of the invention is provides fixing device for air lead a kind of easy to use, safe and reliable for overcoming the defective of prior art.
Fixing device for air lead of the present invention comprises ring-type low bottom-disc, top board and the bolt of being made up of two semi-rings, the two ends of each semi-ring have lug respectively, lug is provided with the screw for bolted on connection, the two ends of top board have respectively with the semi-ring lug on the corresponding through hole that passes through bolt of screw.
During use, earlier low bottom-disc is stuck in the neck location of insulator, utilizes bolt that low bottom-disc and top board are fastened on the insulator upper end, make the lead and the insulator that are arranged in insulator tip position U type groove realize well secured.
Further feature of the present invention, the lower surface of top board can have the circular arc to fovea superior, thereby lead can be fixed between the U of insulator type groove and last concave arc better.
Further feature of the present invention radially is provided with the electrode that extends to both sides at the device low bottom-disc.Like this, when thunderbolt causes electric arc, because the effect of load current or short circuit current; electric arc can be subjected to electric power and waft to the extension electrode outside; thereby electric arc is burnt in the air gap, no longer, protected insulator surface to exempt from electric arc like this and burnt damage along the insulator surface burning.
Low bottom-disc described in the present invention, top board and bolt can be made preferred metal materials by metal material or insulating material.
Because the low bottom-disc of metal fixing device for air lead is pricked silk with original metal and compared, and has bigger cross section and thickness, just is not easy like this to be burnt out under the effect of power frequency continued flow electric arc, its flashback performance is improved greatly, guarantees the safety of system's operation.
Beneficial effect of the present invention is:
(1) simple installation, labour intensity is low;
(2) exemption from inspection is safeguarded in the running, and the anti-performance of burning is outstanding;
(3) security of operation, the reliability height is particluarly suitable for using on the 10kV aerial condutor, is applicable to copper, aluminium aerial condutor.

Embodiment
A kind of typical structure with fixing device for air lead is that example (low bottom-disc is an annulus in the legend) further specifies the present invention below.Certainly, the present invention is not limited only to a kind of structure in this introduction, can further expand based on claim of the present invention.
With reference to Fig. 1～Fig. 3, fixing device for air lead of the present invention comprises circular low bottom-disc 1, top board 2 and the bolt of being made up of two semicircular ring 3, the two ends of each semicircular ring have lug respectively, lug is provided with the screw 4 that connects for bolt 3, the two ends of top board 2 have respectively with the semicircular ring lug on screw 4 corresponding through holes 5.Bolt 3 passes screw 4 stubborn the connecing of through hole 5 and two semicircular ring lugs of low bottom-disc of top board, constitutes whole fixing device for air lead (see figure 1).
Installation steps are specific as follows:
Screw out wherein one piece of bolt of device, two semicircular ring of low bottom-disc are pulled open;
Top board is removed;
Two semicircular ring of low bottom-disc are closed up, block insulator 6 necks;
Aerial condutor 7 is put into the U type groove of insulator;
Mobile top board is pushed down aerial condutor 7 to aerial condutor 7 upper ends with top board, and aerial condutor 7 is between the U type groove of the circular arc of top board and insulator;
The bolt that originally unclamped is passed top board, and enters in the semicircular ring screwed hole of low bottom-disc.;
Evenly tighten both sides and connect top board and two pieces of bolts of low bottom-disc, device is fixed on the insulator neck, so just make aerial condutor 7 and insulator 6 realize fixedly (see figure 4) well.
