Abstract

The utility model relates to an angle-form over-voltage protection device, which is characterized in that a lightning arrester with an insulation conducting wire is connected with an common insulator for a 10kV aerial insulation circuit through a mounting bracket and an auxiliary mounting supporting bar, a spherical (or arc) discharging electrode is respectively and fixedly connected with a fixed bracket A and a fixed bracket B through threads, and the fixed brackets A and B are arranged below the lightning arrester with the insulation conducting wire and a circuit cross-arm. The angle-form over-voltage protection device has the advantages that: the gap distance is adjustable, so the gap distance between two spherical (or arc) discharging electrodes below the lightning arrester and the insulator is maintained consistent and uniform. Since the discharging electrode adopts the spherical (or arc) structure, multi-time discharging can be ensured, and the spherical structure is free from deformation after the discharging. The discharging electrode is made of copper or stainless steel material, so the discharging electrode can resist the corrosion, has elasticity and is free from deformation. The angle-form over-voltage protection device has low cost, simple and beautiful structure and strong practicability.

Description

Angle type overvoltage protection device
Technical field
The utility model is an angle type overvoltage protection device, belongs to overhead transmission line over-voltage protection technique field.
Background technology
The insulated overhead line overwhelming majority suffers indirect lightning strike; when the lightning overvoltage flashover; because overvoltage protection device is in parallel with line insulator; lightning current causes that high potential makes the series gap action of lightning arrester; reduced the potential difference between tower arm and lead; guarantee no longer flashover of insulator; thereby avoided the line tripping power failure; in order to guarantee the operate as normal of overvoltage protection device; must guarantee between outer sparking electrode clearance distance within the limits prescribed, spacer ring of the prior art is processed by 1Gr18Ni9 spring stainless steel wire integral body.Have following problem in the design: 1. processing is relatively difficult; 2. because the wind rotation is moving, can not prevent that spacer ring from moving, and the gap of insulator and spacer ring can not guarantee uniformity.
Summary of the invention
The purpose of this utility model is intended to overcome the defective that prior art exists, and proposes a kind of fixing overvoltage protection device structure of clearance distance between outer sparking electrode that satisfies.
Technical solution of the present utility model: it is characterized in that its structure is that tape insulation lead lightning arrester connects with 10kV insulated overhead line customary insulation by mounting bracket and the auxiliary support bar of installing, sphere or arc sparking electrode are fixed on A fixed support and the B fixed support with thread connection respectively, and A fixed support and B fixed support are installed in the below of tape insulation lead lightning arrester and circuit cross-arm.
With threaded adjusting two interelectrode clearance distances, guarantee that the discharging gap distance is in certain scope.
Advantage of the present utility model: clearance distance is adjustable, guarantees following two globular discharge electrode gap distance uniformities of lightning arrester and insulator.Because sparking electrode adopts spherical (arc) structure, can guarantee multiple discharge, and discharge back spherical structure is indeformable.Sparking electrode adopts stainless steel material, the energy anticorrosion, and it is indeformable to have elasticity.This product low cost, simple in structure, attractive in appearance, practical.
Description of drawings
Accompanying drawing 1 is the structural representation of angle type overvoltage protection device.
Among the figure 1 is the sub-PS-15/3N of 10kV insulated overhead line customary insulation, the 2nd, circuit cross-arm, the 3rd, globular discharge electrode, the 4th, auxiliary support bar, the 5th, A fixed support, the 6th, mounting bracket, the 7th, tape insulation lead lightning arrester, the 8th, the B fixed support installed.
Embodiment
Contrast accompanying drawing, its structure are that tape insulation lead lightning arrester 7 connects with 10kV insulated overhead line customary insulation 1 by mounting bracket 6 and the auxiliary support bar 4 of installing.Spherical (or arc) sparking electrode 3 adopts the good stainless steel material of electric conductivities, is fixed on the A fixed support 5 and B fixed support 8 under tape insulation lead lightning arrester 7 and the circuit cross-arm 2 with thread connection respectively.Can use threaded adjusting two interelectrode clearance distances, guarantee that the discharging gap distance is in certain scope.
Described tape insulation lead lightning arrester 7 is tape insulation lead composite sheath zero-clearance zinc oxide lightning arresters, its structure is that sealing cap and lightning arrester main body form integral structure by hot press moulding, thread connection between sealing cap and wiring body, heat-shrinkable T bush is contained in the binding site of sealing cap and wiring body.
At present, we as research object, discharging gap distance is at 60 ± 5mm with the sub-PS-15/3N of 10kV customary insulation.(remarks: different insulators has different discharging gap distances.Here just introduce for example.) lightning arrester is connected on the insulated overhead line by insulated conductor and penetrating cable clamp.Clearance distance is adjustable like this, guarantees following two spheries (or arc) sparking electrode clearance distance uniformity of lightning arrester and insulator.Because sparking electrode adopts spherical structure, can guarantee multiple discharge, and discharge back spherical structure is indeformable.Sparking electrode adopts copper or stainless steel material, the energy anticorrosion, and it is indeformable to have elasticity.This product low cost, simple in structure, attractive in appearance, practical.
Available threaded adjusting two interelectrode clearance distances guarantee that the discharging gap distance is in certain scope.At present, we as research object, discharging gap distance is at 60 ± 5mm with the sub-PS-15/3N of 10kV customary insulation.(remarks: different insulators has different discharging gap distances.Here just introduce for example.) lightning arrester is connected on the insulated overhead line by insulated conductor and penetrating cable clamp.
