Isihloko: Ukubaluleka kwezithiyo zokuvimba umbani ekuvikeleni umbani

Ukwandaababophi, okwaziwa nangokuthi i-surgeababophi, ziyingxenye ebalulekile yanoma yiluphi uhlelo lokuvikela umbani. Ukushaywa kombani kungaba yinhlekelele futhi kusongela impilo, ngakho-ke ukusetshenziswaizibambi zombaniKubalulekile ukunciphisa imiphumela yokushaywa kombani. Kule bhulogi, sizoxoxa ngokubaluleka kwezithiyo zokuvimba ukukhuphuka kombani ekuvikeleni umbani, ngenkathi sihlola nezingxenye ezakha isithiyo sokuvimbela ukukhuphuka kombani esisezingeni eliphezulu.

Enye yezingxenye ezibalulekile ze-arter yekhwalithi enhle yi-insulation ye-EPDM ephiliswe nge-sulfur esetshenziswa ekwakhiweni kwayo. Ukushaya kombani kudala ama-voltage aphezulu angalimaza imishini ethintana nayo. I-insulation ye-EPDM isiza ukuvikela izingxenye ze-arter ngokunikeza isithiyo phakathi kwe-voltage ephezulu nezingxenye zangaphakathi ze-arter.

Esinye isici esibalulekile sama-surge arresters ukuvikela kwawo ama-semiconductor. Lesi sivikelo esibunjiwe siphinde sisize ekuvikeleni i-arrester ekukhuphukeni kwamandla kagesi aphezulu, njengoba sinikeza indlela yokuthi amandla amaningi alahlwe phansi. Ngaphezu kwalokho, ibhuthi le-EPDM elibunjiwe elinomoya ophansi lihlangabezana nezidingo ze-ANSI/IEEE Standard 592, okuqinisekisa ukuthi linikeza isivikelo esifanele.

I-arrester core ingenye ingxenye ebalulekile ye-arrester esezingeni eliphezulu. I-core iqukethe ipuleti le-valve ye-zinc oxide surge arrester eliphathwe ngenqubo ekhethekile, okwenza lisebenze kahle kakhulu ekusingatheni ukukhuphuka kwamandla kagesi. I-arrester core inesibopho sokuvimbela noma yimuphi umonakalo kagesi emishinini ngokuphambukisa i-voltage eyeqile iye phansi.

Izithiyo zokuvimba ukukhuphuka kwegesi zifaka phakathi ama-probe ahlinzeka ngendlela ethembekile yokuqhuba kanye nokuhlangana kwabesifazane. Ama-probe asetshenziselwa ukuvimbela ukuqhekeka okungenzeka ezindaweni zokuhlangana kwemishini. Ngaphezu kwalokho, ucingo olujiyile lokufaka igesi lungasetshenziswa ukukhipha i-voltage esebenzayo yokucindezela ngemva kokufinyelela endaweni yokubeka igesi, okunciphisa kakhulu amathuba okulimala kwemishini.

Kubalulekile ukuqaphela ukuthi i-arrester kufanele ifakwe endaweni efanele futhi uqaphele lapho uyisebenzisa. I-surge arrester kumele ifakwe kahle futhi ifakwe endaweni efinyeleleka kalula ukuze ilungiswe. Futhi, kufanele ihlolwe njalo ukuqinisekisa ukuthi isebenza kahle.

Ngamafuphi, i-arrester iyingxenye ebalulekile yesistimu yokuvikela umbani. Ngaphezu kokuvikela ekushayweni umbani, ukusetshenziswa kwayo kubalulekile futhi ekunciphiseni umonakalo wemishini nokuvimbela ukulahleka kwedatha ngenxa yokwanda kwamandla. Ukuqonda indima yengxenye ngayinye ye-surge arrester kubalulekile ekunqumeni uhlobo olufanele lwe-arrester okufanele isetshenziswe. Ngomshini wokuvimbela umbani osezingeni eliphezulu kanye nokufakwa nokugcinwa okufanele, amabhizinisi angaphumula ngokuthula azi ukuthi avikelwe kahle kunoma yimiphi imiphumela emibi ebangelwa ukushaywa umbani.
