Description
Technical field
The utility model relates to a kind of device for carrying out isolated insulation to high-voltage arrester lead-in wire, belongs to lightning arrester equipment technical field.
Background technology
Existing 6-10KV high-voltage fence uses zinc oxide composite insulating lightning-protection device in a large number, and conveniently connecing of lightning arrester is drawn, and part lightning arrester employs the high-voltage conducting wires of the rubber-covered be connected with lightning arrester one, as the link connecting lightning arrester and high voltage bus.Certain owing to connecting length when wire dispatches from the factory, and high-voltage board inner cable room limited space, when practice of construction connects and draws, sometimes out of phase lightning arrester insulation lead-in wire is hung together, maybe lead-in wire and out of phase bus or cable are hung together.Because lightning arrester lead-in wire itself has rubber-covered to wrap up; short-period used there will not be problem; but because lap-joint's electric field is assembled in Long-Time Service; the insulation property of rubber crust can be caused to undermine; when rubber crust decreasing insulating to a certain extent after, insulating capacity can worsen rapidly, causes short circuit to be blown out; cause equipment downtime in electric power system low-voltage and system, unnecessary economic loss is caused to continuous seepage.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of lightning arrester lead-in wire isolated insulation device, this isolated insulation device can increase the distance between lightning arrester lead-in wire, improve the insulating capacity between lightning arrester lead-in wire, effectively avoid because the wire insulation that causes of lightning arrester lead-in wire hypotelorism punctures, cause lightning arrester to blow out accident.
The technical scheme solved the problems of the technologies described above is:
A kind of lightning arrester lead-in wire isolated insulation device, the annulus that it is made by insulating material or disk are formed, annulus is two annulus, two annulus are set with at grade, be connected by many pull bars between outer ring annulus with inner ring annulus, many pull bars are uniform around annular ring peripheral, and the external diameter that the internal diameter of inner ring annulus and lightning arrester go between matches, the leaded circular hole in center of disk, the external diameter that the diameter of lead-in wire circular hole and lightning arrester go between matches.
Above-mentioned lightning arrester lead-in wire isolated insulation device, the outer ring annulus of described annulus isolated insulation device and inner ring annulus there is corresponding lead-in wire inlet port, outer ring annulus has pull bar to be connected with the both sides of the lead-in wire inlet port of inner ring annulus respectively, and the external diameter that the gap between two lateral bracing struts and lightning arrester go between closely cooperates.
Above-mentioned lightning arrester lead-in wire isolated insulation device, leadedly on the disk of described disk isolated insulation device enters groove, and it is groove from disk border to lead-in wire circular hole that lead-in wire enters groove, and lead-in wire enters the external diameter that the width of groove and lightning arrester go between and closely cooperates.
The beneficial effects of the utility model are:
The utility model is manufactured by insulating material, the centre bore of annulus or disk is enclosed within lightning arrester lead-in wire, annulus or disk border prop up other phase line, it is made to keep certain distance, increase the distance not between isopic zone electricity body, improve phase insulation effect, avoid the insulator pin insulation breakdown that different phase conductor causes because of hypotelorism.The utility model structure is simple, easy to use, insulation effect remarkable, has good market prospects.
Accompanying drawing explanation
Fig. 1 is using state figure of the present utility model;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is another kind of structural representation of the present utility model.
In figure, mark is as follows: outer ring annulus 1, inner ring annulus 2, pull bar 3, lead-in wire inlet port 4, disk 5, lead-in wire circular hole 6, lead-in wire enter groove 7, lightning arrester 8, lightning arrester lead-in wire 9.
Embodiment
The utility model is the accessory strengthening high-voltage arrester lead wire insulation, adopts ambroin or bakelite manufacture, insulation itself, and has some strength.
Fig. 1,2 displays, a kind of structure of the present utility model is made up of annulus.Annulus is two annulus, and two annulus are set with at grade, are connected between outer ring annulus 1 with inner ring annulus 2 by many pull bars 3, and many pull bars 3 are uniform around annular ring peripheral, the internal diameter of inner ring annulus 2 and lightning arrester go between 9 external diameter match.Inner ring annulus 2 is enclosed within lightning arrester lead-in wire 9, and the edge of outer ring annulus 1 props up other phase line, makes it keep certain distance, increases the distance not between isopic zone electricity body, improves phase insulation effect.
Fig. 1,2 displays, outer ring annulus 1 and inner ring annulus 2 have corresponding lead-in wire inlet port 4, and outer ring annulus 1 has pull bar 3 to be connected with the both sides of the lead-in wire inlet port 4 of inner ring annulus 2 respectively, the gap between two lateral bracing struts 3 and lightning arrester go between 9 external diameter closely cooperate.During use, lightning arrester can be gone between 9 directly through inner ring annulus 2, also can push from the lead-in wire inlet port 4 outer ring annulus 1 and inner ring annulus 2, make lightning arrester lead-in wire 9 arrive inner ring annulus 2, this method is more suitable for the situation of installing this device after lightning arrester lead-in wire 9 connects again.Due to the gap between two lateral bracing struts 3 and lightning arrester go between 9 external diameter closely cooperate, after by lightning arrester lead-in wire 9, from lead-in wire, entrance 4 is forced into, lightning arrester lead-in wire 9 can not be deviate from from lead-in wire entrance 4 easily.
Fig. 3 shows, and another kind of structure of the present utility model is made up of disk 5.The leaded circular hole 6 in center of disk 5, the lead-in wire diameter of circular hole 6 and lightning arrester go between 9 external diameter match.Leadedly on disk 5 enter groove 7, it be groove from disk 5 edge to lead-in wire circular hole 6 that lead-in wire enters groove 7, the go between width that enters groove 7 and lightning arrester go between 9 external diameter closely cooperate.The using method of disk 5 is identical in annulus.
Circular ring structure of the present utility model and disc structure respectively have advantage.Be air insulation between the annulus of circular ring structure, overall weight is light, saves material, reduces costs; Disc structure is entity, and structural strength is large, not fragile.
