Isivikelo sokuqhuma kwe-AC: isivikelo esibalulekile sezinhlelo zikagesi
Ezweni lanamuhla, lapho amadivayisi kagesi eseyingxenye ebalulekile yempilo yethu yansuku zonke, ukubaluleka kokuvikela la madivayisi ekukhuphukeni kwamandla akunakweqiswa. Ama-AC surge protectors (SPDs) ayizindlela ezibalulekile zokuzivikela ekukhuphukeni kwamandla kagesi angalimaza noma abhubhise imishini kagesi ebucayi. Ukuqonda imisebenzi, izinzuzo, kanye nokufakwa kwama-AC surge protectors kubalulekile emakhaya nasemabhizinisini.
Iyini idivayisi yokuvikela ukukhuphuka kwe-AC?
Isivikelo sokukhuphuka kwe-AC (i-SPD) siyidivayisi ekhethekile eyenzelwe ukuvikela imishini kagesi ekukhuphukeni kwamandla kagesi okubangelwa yizici ezahlukahlukene, okuhlanganisa ukushaywa kombani, ukucima kukagesi, kanye nokushintshashintsha kwegridi. Lokhu kunyuka kwamandla kagesi kungenzeka ngokuzumayo futhi ngaphandle kwesixwayiso futhi kungalimaza izinto zasekhaya, amakhompyutha, kanye neminye imishini kagesi. Ama-SPD asebenza ngokuphambukisa amandla kagesi ngokweqile kude nemishini exhunyiwe, ukuqinisekisa ukusebenza okuphephile nokuthembekile kwemishini.
Amadivayisi okuvikela ukukhuphuka kwe-AC asebenza kanjani?
Umsebenzi oyinhloko wesivikelo sokukhuphuka kwe-AC ukubona ukwanda kwe-voltage nokuqondisa amandla angaphezulu abuyele emhlabathini. Lokhu kuvame ukufezwa ngokusebenzisa i-metal oxide varistor (MOV) noma i-gas discharge tube (GDT), esebenza njengesithiyo se-voltage ephezulu. Uma kwenzeka ukuqhuma okukhulu, i-SPD iyasebenza, ivumela i-voltage eyengeziwe ukuthi igeleze kudivayisi futhi ihlakazeke ngokuphephile iye phansi, ivikele imishini exhunyiwe.
Izinzuzo zokusebenzisa idivayisi yokuvikela ukukhuphuka kwe-AC
1. Vikela Imishini Yakho Eyigugu: Enye yezinzuzo ezibaluleke kakhulu zokufaka isivikelo sokuqhuma kwe-AC yisivikelo esisinikeza amadivayisi akho kagesi abizayo. Amakhompyutha, ama-TV, kanye nezinto zasekhaya kungabiza kakhulu ukuzishintsha, kanti isivikelo sokuqhuma kwe-surge (SPD) singandisa isikhathi sazo ngokuvimbela umonakalo ovela ekukhuphukeni kwe-surge.
2. Ukuthula kwengqondo: Ungaqiniseka ukuthi uhlelo lwakho lwamandla luvikelekile ekukhuphukeni kwamandla okungalindelekile. Lokhu kubaluleke kakhulu emabhizinisini athembele emishinini ebucayi yokusebenza kwansuku zonke.
3. Isixazululo esingabizi kakhulu: Ukutshala imali kusivikelo sokuqhuma kwe-AC kungongela imali ngokuhamba kwesikhathi. Izindleko zokushintsha imishini kagesi eyonakele zingadlula kakhulu utshalomali lokuqala kusivikelo sokuqhuma kwe-AC.
4. Ukuphepha okuthuthukisiwe: Ukwanda kwamandla kagesi akugcini nje ngokulimaza imishini, kodwa futhi kungadala izingozi zokuphepha, njengemililo kagesi. Ama-SPD anciphisa lezi zingozi ngokuqinisekisa ukuthi ama-overvoltage aqondiswa ngokuphephile.
Ukufakwa kwedivayisi yokuvikela ukukhuphuka kwe-AC
Inqubo yokufaka isivikelo sokukhuphuka kwe-AC ilula, kodwa kunconywa ukuthi sifakwe uchwepheshe kagesi oqeqeshiwe ukuqinisekisa ukuphepha nokuhambisana namakhodi kagesi endawo. Ama-SPD angafakwa ezindaweni ezahlukahlukene ohlelweni lukagesi, kufaka phakathi iminyango yesevisi, amaphaneli okusabalalisa, noma njengendawo yokusetshenziswa kwezinto zikagesi ngazinye.
Uma ukhetha isivikelo sokukhuphuka kwe-AC, kufanele ucabangele i-voltage elinganisiwe yedivayisi, i-surge current elinganisiwe, kanye nesikhathi sokuphendula. Lezi zici zizonquma ukusebenza kahle kwedivayisi yokuvikela ye-SPD.
Ngokufigqiwe
Sekukonke, izivikelo zokuqhuma kwe-AC ziyingxenye ebalulekile yanoma yiluphi uhlelo lukagesi, zihlinzeka ngokuvikelwa okusebenzayo ekukhuphukeni kwamandla okungalindelekile. Ngokutshala imali ezivikelweni zokuqhuma kwegesi, amakhaya namabhizinisi angavikela amadivayisi awo kagesi abalulekile, andise ukuphepha, futhi anikeze ukuthula kwengqondo. Njengoba ubuchwepheshe buqhubeka nokuthuthuka futhi ukuthembela kwethu kumadivayisi kagesi kukhula, ukuvikelwa kokuqhuma kwegesi kuzoba kubaluleke kakhulu, okwenza kube ukutshalwa kwezimali okuhlakaniphile kwesikhathi esizayo.
