Namen
Na SN daljnovodih, kjer trasa poteka skozi gozd, pogosto
prihaja do prekinitev napajanja zaradi: neurij, podiranja
dreves, lomljenja vej, otresanja snega in žleda. V najhujših
primerih prihaja do porušitve DV. Dejstvo je, da pri teh
porušitvah v večini primerov ostane vodnik nepretrgan.
Zaradi tega smo v našem podjetju skupaj z uporabniki
in strokovnimi sodelavci izvedli študijo o varni montaži
DV skozi gozd. Raziskave smo podkrepili s preskusom v
naravi (video na
.
Oprema
Za izvedbo varne montaže skozi gozd so uporabljeni:
• podporni kompozitni izolatorji tip PKI z oslabljeno
vzmetno sponko
• kavelj
• varnostni lok
Izračuni
Premer loka in dimenzije kavlja je potrebno določiti z
izračunom.
Naročanje
Za izvedbo »varne montaže skozi gozd« zahtevajte
ponudbo na osnovi:
• trasnega načrta
• preseka vodnika
The purpose
OnMV power lines, where the route passes through the forest,
supply interruptions often come due to: storms, falling trees,
breaking branches, shaking of snowand ice. In the worst
cases, it comes towrecking of PL. The fact is that inmost cases
whenwrecking occurs the wire remains undamaged. For this
reason, we have in our company, together with customers
and technical staff conducted a study on the safe installation
of PL through the woods. Researchwas reinforced by the test
in nature (video onwww.izoelektro.com).
Equipment
To implement safe installation through the woods are used:
• post composite insulators type PKI with weakened
spring clamp
• hook
• safety wire arc
Calculations
Arc diameter and hook size should be determined by
calculation.
Ordering
To implement »safe installation through the woods« request
a quote based on:
• power line plan
• wire cross-section
