Description
Technical field
The utility model belongs to arrester technical field, in particular to a kind of arrester link insulator.
Background technique
In power distribution network, solves the corridor that naked high-voltage conducting wires can't resolve using Insulating A High-Voltage conducting wire and asked with safety
Topic, but Insulating A High-Voltage conducting wire also has the weakness of its own, i.e. lightning-caused breaking problem, and so-called lightning stroke must break.With in power distribution network
The problem of increase of Insulating A High-Voltage conducting wire covering surface, lightning-caused breaking, is also increasingly apparent.It is therefore prevented that overhead insulating high-voltage conducting wires thunder
Line is struck off to become more and more important.
According to the mechanism of Insulating A High-Voltage conducting wire lightning-caused breaking, the corresponding precautionary measures have " dredge and block " two ways.
" dredging " is exactly so that power frequency arc arc root is shifted or is fixed on the Insulating A High-Voltage conducting wire part bare wire near ceramic insulator
It burns on special fitting, to protect conducting wire from burn.The mode of " leading-type " is easy to operate, small investment, but conducting wire part
Exposed, there are sealings and insulation defect." blocking " is exactly the prevention power frequency continued flow starting the arc after lightning stroke flashover.It is " stifled compared to " leading-type "
The better protecting effect of plug ", the disadvantage is that construction is relative complex, higher cost.
In high pressure overhead power line, the thunder And Lightning Preventive Measures generally used are by using Clamping porcelain insulating
Son is fixed on electric arc on insulator upper mounting seat and run-on tab and burns, prevent lightning-caused breaking and porcelain vase from bursting.In high voltage overhead
In transmission line of electricity, other than Clamping porcelain insulator, also carried out through the mode frequently with insulator parallel connection arrester with gaps
Lightning protection.Arrester with gaps uses " blocking type " lightning protection principle, can be avoided route and trips because of lightning stroke.
In high pressure overhead power line, the thunder And Lightning Preventive Measures generally used are by using Clamping porcelain insulating
Son is fixed on electric arc on insulator upper mounting seat and run-on tab and burns, prevent lightning-caused breaking and porcelain vase from bursting.But it discharges
There is the following in clamp porcelain insulator:
(1) although can prevent route from the accidents such as bursting because insulator occurs in lightning stroke, it cannot prevent route from jumping because of lightning stroke
Lock cannot reduce trip-out rate；
(2) since thunder discharge path distance insulator umbrella is closer, power frequency arc fires after lightning discharge in some cases
It will cause bursting or burning for insulator umbrella when burning.
As shown in the above, existing Clamping porcelain insulator can not reliably solve the problems, such as lightning-caused breaking, stablize
The low, poor reliability of property, there are serious security risks.
In high pressure overhead power line, other than Clamping porcelain insulator, also through frequently with insulator parallel connection interband
The mode of gap arrester carries out lightning protection.Arrester with gaps uses " blocking type " lightning protection principle, can be avoided route because of thunder
It hits and trips, protecting effect is good.But there is the following in arrester with gaps:
(1) insulator needs are used cooperatively with arrester, are installed respectively, and installation workload is increased, and are invested bigger.
(2) adjusting when lightning arrester gap distance needs to install is easy to cause protecting effect bad because of clearance distance inaccuracy,
There are security risks.
As shown in the above, existing arrester with gaps increases installation workload, and there are security risks.
In addition, existing ceramic insulator, the position of upper steel cap and conductive contact are typically provided with one with cambered
Copper sheet.The copper sheet is directly contacted with conducting wire, very thin thickness, sharp edges.In the operation of long-term, conducting wire wind put, conducting wire from
Under the action of body gravity, insulated hull even aluminium wire is easy to be cut off by copper sheet, forms fault point, exists in During Process of Long-term Operation tight
The security risk of weight.
In tension-resistant rod, link insulator is had a wide range of applications.Once link insulator broken by lightning, it is likely that can fall
Line causes to damage more serious consequence than support insulator.The country generally uses band gap to the protection of link insulator at present
The measure of arrester, but due to needing to be coupled with insulator, often it is in the presence of that protecting effect is undesirable.
