Odvodniki z vgrajenimi ZnO varistorji imajo veliko upornost. Ob nastopu prenapetosti se upornost zmanjša v času 25 ns. Zaradi tega ima odvodnik sposobnost odvajanja velikih impulzivnih tokov v kratkem času. Po prenehanju prenapetosti se upornost ponovno poveča na prvotno stanje. Odvodniki tip 2SS15N in 2SS15N-N vzdržijo najmanj 20 udarov atmosferskih praznjenj. Izračun in izbira Posebno pozornost je potrebno nameniti izbiri ustreznega tipa ZnO odvodnika. 1.

36 Podporni kompozitni izolatorji PKI Splošno Izkušnje uporabnikov in termovizijski posnetki daljnovodov dokazujejo, da v času življenjske dobe prihaja do parcialnih praznitev, kadar je goli ali pol izoliran vodnik vpet v kovinsko pritrdišče. Študija porazdelitve električne poljske jakosti na kovinski glavi kompozitnega podpornega izolatorja potrjuje, da obstaja velika verjetnost, da bo zaradi previsoke električne poljske jakosti ob dolgotrajni uporabi izolatorjev z zgornjim kovinskim priključkom, prišlo do prežiga na mestu spodnjega roba zgornjega priključka izolatorja ali do odžiga vodnika na mestu pritrditve. Teoretične raziskave so pokazale, da se v obratovanju vzdolž izolatorja vzpostavi električno polje, ki ni homogeno temveč je odvisno od lastnosti materialov in geometrije. To vpliva na dielektrične obremenitve izolatorja, ki so odvisne od oblike prevodnih delov in rastejo z velikostjo napetosti U oziroma električnega polja E. Post line composite insulators PKI Generally Experiences of users and thermo-vision snaps of power lines are proving that partial discharges occur in time of lifespan when bare conductor or covered conductor is fastened to metal fitting. Study of distribution of electric field strength on metal upper fitting of composite line post (support) insulator confirms that there is high probability that because of too high electric field strength, at long duration use of insulators with upper metal fitting, will come to burns on spot of lower end of upper fitting of insulator or that conductor will burn off from its place of fixation. Theoretical researches showed, that while in operation a non-homogenous electric field, which depends on material characteristics and insulator geometry, is established along the insulator. This affects on dielectric loads of insulator, which depends upon the shape of conducting parts and increases with height of voltage U or of electric field E. 36 Diagram električne poljske jakosti (MV/m) 8,0 7,0 6,0 5,0 4,0 3,0 2,0 1,0 MEJNA VREDNOST izolator z izolacijsko glavo izolator s kovinsko glavo Distribution of electric field strength (mm) Izolator tip PKI PA z zgornjim priključkom iz izolacijskega materiala je rezultat strokovnih raziskav in praktičnih izkušenj uporabnikov naših izdelkov. Odpravlja pomanjkljivosti izolatorjev s kovinskim zgornjim priključkom. Zgornji priključek je izdelan iz poliamida PA6 z dodatkom steklenih vlaken, kar mu zagotavlja ustrezne mehanske lastnosti, časovno stabilnost, odpornost na atmosferske vplive in UV svetlobo. Je značilne črne barve. Ta material že več kot deset let uspešno uporabljamo v naši nihajni sponki. Insulator type PKI PA with upper fitting from insulating material is result of professional researches and of practical experiences of users of our products. It eliminates deficiencies of insulators with metal upper fitting. Upper fitting is made from polyamide PA6 with addition of glass fibres, which is assuring suitable mechanical characteristics, lifetime stability, resistance to atmospheric influences and UV light. It has characteristically black colour. Already more than ten years we successfully use this material for our spring clamp.
