Iingenelo zeZinc Oxide Arresters ezinee-Convents zangoku ezakhelwe ngaphakathi

1). Iingxaki ngemveliizithinteli ze-zinc oxide.

1. Kukho ingozi efihlakeleyo yokhuseleko emsebenzini
Okwangoku,izithinteli ze-zinc oxidezifakelwe kunye nezixhobo zokubeka esweni, kwaye ulwakhiwo lwazo luboniswe kumfanekiso ongezantsi.

Xaisithinteli se-zinc oxideXa isebenza, uxinzelelo oluthile olushiyekileyo luya kuveliswa kwi-R1 kwisixhobo sokujonga. I-voltage eseleyo eveliswa zizixhobo ezahlukeneyo zokujonga iya kwahluka, kodwa ngokwemigaqo ye-“AC Gapless Metal Oxide Lightning Arrester” (GB 11032), i-voltage eshiyekileyo inokufikelela kwi-3kV. Ngamanye amazwi, i-terminal yokufaka yesixhobo sokujonga iya kuba ne-voltage eshiyekileyo ukuya kuthi ga kwi-3kV xa i-arrester isebenza. Le voltage eshiyekileyo iya kufakwa kwi-voltage eshiyekileyo emva kokuba i-zinc oxide arrester isebenze, nto leyo enyusa ixabiso le-voltage eshiyekileyo iyonke ye-zinc oxide arrester, enefuthe elibi ekucinezeleni ngempumelelo i-overvoltage. Umzekelo, iisithinteli-mbanekwisitishi esingaphantsi esine-voltage elinganisiweyo ye-10kV, kunye nomsinga wokukhupha oqhelekileyo we-5kA, ixabiso eliqhelekileyo le-voltage eseleyo yomsinga wombane yi-27kV. Ukuba i-voltage eseleyo ye-3kV yesixhobo sokujonga ibekwe ngaphezulu, i-voltage eseleyo iyonke ye-arrester iya kufikelela kwi-30kV, kwaye i-voltage eseleyo iya kunyuka nge-11.1%, eya kutshintsha kakhulu iimpawu zokusebenza ze-arrester kwaye yenze buthathaka isiphumo se-arrester sokucinezela i-overvoltage.

Ukuze kube lula ukuba abasebenzi abasebenza apho bajonge baze babhale phantsi idatha,isithinteli se-zinc oxideisixhobo sokujonga ngokubanzi sifakwa kwindawo emalunga ne-1.8m ukusuka emhlabeni. Ukuba kukho i-voltage ephezulu ye-3kV xa isixhobo sokujonga singena, kuya kubakho umngcipheko omkhulu wokhuseleko kukhuseleko lomntu lomsebenzi.

2. Kukho iingozi ezifihlakeleyo ekuthembekeni kokusebenza

Ucingo lwendlela yendabukoisithinteli se-zinc oxidekwaye isixhobo sokufumanisa siboniswe kuMfanekiso 1 ngezantsi. Phakathi kwazo, isiseko sokukhusela, ucingo, kunye nesixhobo sokujonga zonke zizixhobo ezongezelelweyo zokulinganisa umbane ovuzayo we-zinc oxide arrester phantsi kwevolthi yokusebenza. Ezi zixhobo azifuneki ekusebenzeni okuqhelekileyo kwe-zinc oxide arrester ngokwayo. Ukongezwa kwezi zixhobo ezongezelelweyo kwandisa amathuba okuba kubekho iziphene kwizixhobo. Nokuba zeziphi izixhobo ezineziphene, kunokubangela ukuba i-arrester iyeke ukusebenza kwaye kuchaphazele ukuzinza kokusebenza kwezixhobo. Umzekelo, kumsebenzi wokwenyani, isiseko sokukhusela sihlala sineengxaki zokufuma, ukufakelwa okungaqhelekanga okanye umonakalo, oya kuchaphazela ukusebenza kunye nokubekwa kweliso kwe-arrester.

Ngokwezibalo ezikwi-intanethi, phakathi kweziphene ezinzulu nezibalulekileyo ze-zinc oxide arresters kunyaka othile, bekukho iziphene ezingama-21 emzimbeni, i-110 leaking currents engaqhelekanga, i-13 engaqhelekanga ye-insulation yangaphandle, i-1 engaqhelekanga yesiseko (i-flange), ii-conductors ezingaqhelekanga ezi-8, kunye neengxaki ze-drainage line ezili-10. Isixhobo sokujonga besingaqhelekanga izihlandlo ezili-183. Kuyabonakala ukuba izixhobo ezongezelelweyo ziya kuba nefuthe elikhulu ekusebenzeni okuzinzileyo kwe-arrester. Olunye ulwazi lwezibalo lubonisa ukuba iziphene ezingama-2,509 zenzeka kwi-light arresters ezingama-110 (66) kV nangaphezulu kunyaka othile, apho iziphene ze-arrester ngenxa yokulinganisa i-leaking current engaqhelekanga zaba yi-31.79% yenani lilonke leziphene, kwaye iziphene zezixhobo zokujonga zaba yi-52.89%.
