Isivikelo sokwanda: Ukuvikelwa okubalulekile kwamadivayisi kagesi
Ezweni eliya ngokuya likhula ngedijithali, abantu bathembele kakhulu kumadivayisi kagesi kunanini ngaphambili. Kusukela kuma-smartphone nama-laptop kuya kumishini yasekhaya kanye nemishini yezimboni, la madivayisi aseyingxenye ebalulekile yempilo yethu yansuku zonke. Kodwa-ke, lokhu kuncika kuletha nengozi yokwanda kwamandla kagesi, okungadala umonakalo omkhulu kumadivayisi ethu kagesi. Yilapho amadivayisi okuvikela ukuqhuma (ama-SPD) eba abaluleke kakhulu.
Izivikelo zokuphakama kwegesi zenzelwe ukuvikela imishini kagesi ekukhuphukeni kwamandla kagesi. Lezi zinhlayiya zingabangelwa yizizathu ezahlukahlukene, okuhlanganisa ukushaywa kombani, ukucima kukagesi, ngisho nokusebenza kwemishini emikhulu esebenzisa amandla amaningi. Uma kwenzeka ukuqhuma okukhulu, kungadlula izingxenye ze-elekthronikhi zedivayisi, kubangele ukuthi isebenze kabi noma yehluleke ngokuphelele. Ama-SPD asebenza njengesivikelo, ephambukisa amandla kagesi amaningi asuke emishinini ebucayi, egcina iphephile.
Ukubaluleka kokuvikelwa kokukhuphuka kwamandla akunakweqiswa. Ngokusho kweNational Fire Protection Association (NFPA), ukwanda kwamandla kagesi kubangela izinkulungwane zemililo kanye nezigidi zamaRandi emonakalweni wempahla minyaka yonke. Ngokutshala imali ku-protector yokukhuphuka kwamandla esezingeni eliphezulu, abantu ngabanye kanye namabhizinisi bangavikela ukutshalwa kwezimali kwabo futhi bagweme ukulungiswa okubizayo noma ukushintshwa.
Kunezinhlobo ezahlukene zezivikeli zokukhuphuka (ama-SPD) ezitholakala emakethe, ngayinye inenhloso ethile. Izivikeli zokukhuphuka ezifakwayo zivamile kakhulu eziphakelini zamandla zasekhaya. Lawa madivayisi afana nemigqa yamandla, kodwa anezivikelo zokukhuphuka ezakhelwe ngaphakathi. Zilungele ukuvikela amadivayisi kagesi omuntu siqu njengamakhompyutha, ama-TV, nama-consoles emidlalo. Ukuze uthole isivikelo esibanzi, izivikeli zokukhuphuka zendlu yonke zingafakwa ebhodini lokusabalalisa. Lawa madivayisi angumugqa wokuqala wokuzivikela ekukhuphukeni okungenela uhlelo lukagesi lwendlu.
Ezindaweni zezentengiselwano nezezimboni, isidingo sokuvikelwa okuqinile kokukhuphuka kwamandla sibaluleke kakhulu. Amabhizinisi avame ukuthembela emishinini nasemishinini ebizayo engathinteka kakhulu ukukhuphuka kwamandla. Amadivayisi okuvikela ukukhuphuka kwamandla ezimboni (ama-SPD) aklanyelwe ukuphatha amazinga aphezulu kagesi futhi angavikela lonke uhlelo, aqinisekise ukuthi ukusebenza akuphazanyiswa nokuthi imishini ihlala isebenza.
Uma ukhetha isivikelo sokukhuphuka, kunezinto eziningana okumele zicatshangelwe. I-voltage yedivayisi yokubopha, isikhathi sokuphendula, kanye nomthamo wokumunca amandla yizinto ezibalulekile ezinquma ukusebenza kwayo. I-voltage yokubopha ibhekisela ezingeni le-voltage lapho isivikelo sokukhuphuka (i-SPD) siqala khona ukuguqula i-overvoltage. Uma i-voltage yokubopha iphansi, kulapho isivikelo semishini ebucayi siba ngcono khona. Isikhathi sokuphendula sibonisa ukuthi idivayisi isabela ngokushesha kangakanani ekukhuphukeni, futhi lapho isikhathi sokuphendula sishesha, kulapho isivikelo siba ngcono khona. Umthamo wokumunca amandla ulinganisa inani lamandla idivayisi engawamunca ngaphambi kokuba yehluleke, ngakho-ke kuyisici esibalulekile ezindaweni ezinamandla aphezulu.
Ngaphezu kokuvikela imishini, ama-SPD andisa impilo yamadivayisi kagesi. Ngokuvimbela umonakalo ovela ekukhuphukeni kwamandla, la madivayisi asiza ekugcineni ukusebenza kwemishini nokuthembeka kwayo isikhathi eside. Lokhu kubaluleke kakhulu kumabhizinisi athembele kubuchwepheshe ukuze asebenze, njengoba isikhathi sokungasebenzi singaholela ekulahlekelweni kwemali engenayo kanye nokukhiqiza.
Sekukonke, isivikelo sokukhuphuka kwamandla kagesi siwutshalomali olubalulekile kunoma ubani osebenzisa amadivayisi kagesi. Kungakhathaliseki ukuthi kusemakhaya noma endaweni yezentengiselwano, ukuvikela ekukhuphukeni kwamandla kagesi kubalulekile ekugcineni ukusebenza kanye nesikhathi sokuphila kwemishini yakho. Kunezinhlobonhlobo zezivikelo zokukhuphuka kwamandla kagesi ezitholakala emakethe, futhi kubalulekile ukukhetha eyodwa ehlangabezana nezidingo zakho ezithile. Ngale ndlela, ungaqinisekisa ukuthi amadivayisi akho kagesi asebenza ngokuphepha nangokuthembekile, okukunikeza ukuthula kwengqondo kuleli zwe elikhula ngamandla kagesi.
