FJH Ging Grading for Insulator
Sharaxaad:
Giraan qiimeynta ayaa sidoo kale loo adeegsadaa qalabka korantada sareeyo.Faraanti qiimeynta waxay la mid yihiin giraangiraha koronto, laakiin waxay ku wareegaan dahaarka halkii ay ka ahaan lahaayeen kirishbooyada.In kasta oo laga yaabo inay sidoo kale u adeegaan si ay u xakameeyaan korona, ujeeddadooda ugu weyn waa inay yareeyaan qulqulka suurtagalka ah ee ku jira daaha, ka hortagga burburka korantada ee dhicisoobay.
Dheefta suurtagalka ah (beerka korantada) ee dahaarka ma aha labis, laakiin waxa ugu sarreeya dhammaadka ku xiga korantada sare ee korontada.Haddii lagu sameeyo danab sare oo ku filan, dahaadhiyuhu wuu jabayaa oo marka hore wuu socon doonaa.Marka qayb ka mid ah insulator-ka dhamaadka ay koronto ahaan u jabto oo ay noqoto mid korantada, tamarta buuxda ayaa lagu dabaqayaa dhererka soo haray, markaa burburku wuxuu si dhakhso ah uga sii gudbi doonaa dhamaadka danabka sare una gudbayaa kan kale, fallaadho toos ah ayaa bilaabmaya.Sidaa darteed, insulators-ku waxay istaagi karaan koronto aad u sarreeya haddii jaangooyooyinka suurtagalka ah ee dhamaadka danabka sare la yareeyo.
Giraanta qiimayntu waxa ay ku wareegsan tahay dhamaadka daahiyaha ee ku xiga dabaylaha tamarta sare.Waxay yaraynaysaa gradient-ka dhamaadka, taasoo keentay in xitaa korantada sii kordheysa oo weheliso insulator-ka, taas oo u oggolaanaysa insulator gaaban oo ka jaban in loo isticmaalo danab la bixiyay.Faraanti qiimeyntu waxay sidoo kale yareysaa gabowga iyo xumaanta dahaarka ka dhici kara dhamaadka HV sababtoo ah goobta koronto ee sareysa.
