Abstract

The utility model provides a take resilient means's metal oxide lightning arrester, includes base, arrester inner core, insulating layer, lead wire is down connected to arrester inner core lower extreme, the one end that goes between is connected to arrester inner core upper end through the elastic mechanism other end connectiong lead flange that goes between on, the utility model relates to a take resilient means's metal oxide lightning arrester adopts all insulation composite covering insulating layer, and it is big to have a security, and the reliability is high, a plurality of advantages that the appearance is pleasing to the eye. And set up the arrester elastic mechanism, and making the installation, repacking strong adaptability has avoided the resource -wasting, has strengthened the durability of equipment, the reliability.

Description

A kind of metal oxide arrester of band elastic device
Technical field
This utility model relates to a kind of lightning arrester, the metal oxide arrester of a kind of band elastic device.
Background technology
In the wild in distribution facility, various lightning arresters are requisite, and spark gap is to be widely used in distribution transformer, on-load switch and the important device of other distribution facility lightning protections.The most commonly used connected mode has dock, separate type, even direct-type.
Dock: be to be blocked by lead-in wire, and crimp binding post respectively, is fixed on spark gap binding post by binding post, uses dock method of attachment, uses binding post two, and need to use relevant crimping tool on material.
Separate type: being gone out to draw at least two lead-in wires by power supply, wherein a lead-in wire is directly connected to spark gap binding post, and remaining lead-in wire is connected to be protected electric utility; it is that spark gap need to access special lead-in wire in brief; this type of connection, adds wire and uses, add cost payout.
Direct-type: be lead-in wire to be fabricated to screw eye be directly crimped on spark gap binding post, though this connection labor and material saving, but due to the directly contact of different metal, affected by natural climate, easily cause oxidation and cause loose contact, even can not play lightning protection function, and not meet installation provision requirement.
Summary of the invention
For solving above-mentioned technical problem, this utility model provides the metal oxide arrester of a kind of band elastic device, and whole lightning arrester insulated enclosure is protected, and is arranged on electic protection position;Owing to being provided with on spark gap lead-in wire spring caps, lead-in wire is mobile and external equipment moves and can adapt to.
This utility model be the technical scheme is that
The metal oxide arrester of a kind of band elastic device, including base, spark gap inner core, insulating barrier, spark gap inner core lower end connects lower lead-in wire, and spark gap inner core upper end connects the one end that goes between, upper lead-in wire other end connecting lead wire flange by elastic mechanism.
Described insulating barrier sealed envelope spark gap inner core, elastic mechanism, upper lead-in wire.
Described elastic mechanism is the helical spring body that a lead material is made, and this helical spring body freely stretches along with upper lead-in wire displacement energy.
Described lower lead-in wire connects ground wire.
Being provided with circular hole in the middle part of described lead-in wire flange, this circular hole is for being connected with outside line bolt.
Outside described lead-in wire flange, sheath is set.
The metal oxide arrester of this utility model a kind of band elastic device, uses all insulation composite sheath insulating barrier, has safety big, and reliability is high, multiple advantages of good looking appearance.And spark gap elastic mechanism is set, make installation, reequip strong adaptability, it is to avoid waste resource, enhance the ruggedness of equipment, reliability.
Accompanying drawing explanation
Fig. 1 is this utility model spark gap structural representation.
Detailed description of the invention
As shown in Figure 1, a kind of metal oxide arrester of band elastic device, including base 1, spark gap inner core 2, insulating barrier 5, spark gap inner core 2 lower end connects lower lead-in wire 4, spark gap inner core 2 upper end connects upper lead-in wire 3 one end, upper lead-in wire 3 other end connecting lead wire flange 7 by elastic mechanism 6.
Base 1 is circular, is positioned at this utility model spark gap lower end.
The lightning-arrest main core that spark gap inner core 2 is made for metal-oxide.
Described insulating barrier 5 sealed envelope spark gap inner core 2, elastic mechanism 6, upper lead-in wire 3.Insulating barrier 5 is to be attached to the composite insulation layer outside spark gap, and whole lightning arrester insulation is sealed protection.
Described elastic mechanism 6 is the helical spring body that a lead material is made, and this helical spring body freely stretches along with upper lead-in wire 3 displacement energy.
Described lower lead-in wire 4 is positioned at the downside of this utility model spark gap, is connected with ground wire.
Being provided with circular hole in the middle part of described lead-in wire flange 7, this circular hole is for being connected with outside line bolt.
Described lead-in wire flange 7 is outside arranges sheath 8.
The metal oxide arrester of this utility model a kind of band elastic device, is arranged on electic protection position, and owing to arranging elastic mechanism 6, the upper lead-in wire 3 of spark gap moves and moves can adapt to external equipment.
