Izinzuzo ze-66kV zinc oxide arrester

Njengoba isidingo sezinhlelo zokusabalalisa amandla ezithembekile nezisebenzayo siqhubeka nokukhula, isidingo semishini yokuvikela ukukhuphuka okuthuthukisiwe sesibe yinto ebalulekile. Umdlali obalulekile kulo mkhakha yi-Isivimbeli sokukhuphuka kwe-zinc oxide esingu-66kV,yakhelwe ukuhlinzeka ngokuvikelwa okuphezulu kwe-overvoltage kwemigqa yokusabalalisa kanye nemishini yesiteshi sikagesi. Lesi sibambeli esisezingeni eliphezulu sisebenzisa i-zinc oxide kanye nezinye i-metal oxides njengediski yokumelana eyinhloko, okuthuthukisa kakhulu izici zayo ze-volt-ampere kanye namakhono okudlulisa ugesi uma kuqhathaniswa nezibambeli zendabuko.

Ama-66kV zinc oxide surge arresters anikeza izinzuzo eziningana ezibalulekile ezenza zibe yingxenye ebalulekile yanoma yiluphi uhlelo lokusabalalisa lwesimanje. Enye yezinzuzo zayo ezibaluleke kakhulu ukwanda kwamandla okuphatha amandla kagesi ku-voltage yokusebenza ejwayelekile. Lokhu kusho ukuthi ama-light arresters anganciphisa ngempumelelo imiphumela yezehlakalo ze-overvoltage, avikele imishini ebalulekile kanye nengqalasizinda ekulimaleni okungenzeka. Ngaphezu kwalokho, ukusetshenziswa kwe-zinc oxide kanye nezinye i-metal oxides njengediski yokumelana eyinhloko kuthuthukisa ukuqina nokuthembeka kwe-arrester, okuqinisekisa ukusebenza kwesikhathi eside ezindaweni zokusebenza eziyinselele.

Ngaphezu kokusebenza okuthuthukisiwe, izibambi ze-zinc oxide ezingama-66kV zinikeza amakhono okuphatha amandla athuthukisiwe, okwenza zibe zilungele ukusetshenziswa kokusabalalisa amandla okunzima. Umklamo kanye nesakhiwo sazo esithuthukisiwe kuqeda amandla ngempumelelo ngesikhathi semicimbi ye-overvoltage, kuvikela ngempumelelo lonke uhlelo lokusabalalisa emiphumeleni elimazayo yokushaya kombani kanye nokunye ukuphazamiseka kukagesi. Leli zinga lokuvikela libalulekile ekugcineni ubuqotho bengqalasizinda ebalulekile kanye nokunciphisa isikhathi sokungasebenzi ngenxa yokuphela kukagesi.

Ngaphezu kwalokho, izibambi zokushisa ze-zinc oxide ezingama-66kV zenzelwe ukuhlinzeka ngokuvikelwa kwe-overvoltage okungabizi kakhulu, okwenza kube utshalomali oluhlelekile lwezinsizakusebenza zokusabalalisa kanye nabaqhubi. Ukusebenza kwayo okuphezulu kanye nokuthembeka kunciphisa isidingo sokulungiswa nokufakwa kabusha njalo, okuholela ekongeni izindleko zokusebenza zesikhathi eside. Ngaphezu kwalokho, ikhono layo lokusingatha ngempumelelo ukwanda kwamandla aphezulu kunciphisa ingozi yokulimala kanye nokwehluleka kwemishini, okuqhubeka nokuba negalelo ekongeni izindleko kanye nokusebenza kahle kokusebenza.

Ngamafuphi, i-66kV zinc oxide arrester imelela intuthuko enkulu kubuchwepheshe bokuvikela i-overvoltage yezinhlelo zokusabalalisa. Ukusebenza kwayo okuphezulu, amakhono okuphatha amandla kanye nokusebenza kahle kwezindleko kuyenza ibe yingxenye ebalulekile ekuqinisekiseni ukuthembeka nokuqina kwengqalasizinda yokusabalalisa amandla yesimanje. Ngokufaka izinto ezithuthukisiwe namasu okwakha, i-arrester ibeka indinganiso entsha yokunciphisa imiphumela yezehlakalo ze-overvoltage, ukuvikela imishini ebalulekile kanye nokunciphisa ingozi yokusebenza. Njengoba isidingo sokusabalalisa amandla okuthembekile nokusebenza kahle siqhubeka nokukhula, ama-66kV zinc oxide surge arresters ayisisombululo esithembekile nesibalulekile sokuhlangabezana nezidingo ezishintshayo zemboni.
