    Idivayisi Yokuvikela Ukuqhuma 1 (1)

    Ezweni lanamuhla eliqhutshwa ubuchwepheshe, amadivayisi kagesi abe yingxenye ebalulekile yempilo yethu yansuku zonke, futhi ukuqinisekisa ukuphepha nokuphila isikhathi eside kwala madivayisi kubalulekile. Njengoba ukwanda kwamandla kwenzeka kakhulu, ukutshala imali kumadivayisi okuvikela ukukhuphuka kwamandla kuba yinto ebalulekile. Lawa madivayisi ahlinzeka ngesendlalelo esengeziwe sokuzivikela ekukhuphukeni kwamandla kagesi okungazelelwe okungalimaza noma kubhubhise imishini yakho kagesi.

    Amadivayisi okuvikela ukukhuphuka (ama-SPD) aklanyelwe ukuphambukisa i-voltage eyengeziwe kude nemishini yakho ngesikhathi sokukhuphuka kwamandla. Ukukhuphuka kwamandla kungabangelwa ukushaya kombani, ukushintsha kwegridi yokusetshenziswa, noma ukwehluleka kwemishini. Ngaphandle kokuvikelwa okwanele, lokhu kukhuphuka kwamandla kungalimaza imishini yakho kagesi, kubangele umonakalo ongenakulungiswa kanye nokulahlekelwa yimali.

    Ama-SPD asebenza ngokuqapha nokulawula ukugeleza kwamandla kagesi kudivayisi. Uma kutholwa ukuqhuma okukhulu, idivayisi idlulisela ngokushesha i-voltage eyeqile phansi, iyivimbele ukuthi ifinyelele imishini yakho eyigugu. Lokhu kuqinisekisa ukuthi amadivayisi akho kagesi athola amandla aqhubekayo futhi aphephile, okwandisa isikhathi sawo sokuphila futhi agweme ukulungiswa okubizayo noma ukushintshwa.

    Enye yezinzuzo eziyinhloko zesivikelo sokukhuphuka kwamandla kagesi ukuthi sisebenza ngezindlela eziningi. Singasetshenziswa ezindaweni zokuhlala, zezentengiselwano kanye nezezimboni ukuvikela imishini ehlukahlukene kagesi. Kusukela kuma-TV namakhompyutha kuya eziqandisini kanye nama-air conditioner, yonke imishini kagesi ingazuza ngokufaka i-SPD.

    Ngaphezu kwalokho, amadivayisi okuvikela ukukhuphuka kwegesi kulula ukuwafaka futhi ahlinzeka ngesisombululo esingabizi kakhulu sokuvikela imishini yakho kagesi. Ngomklamo wawo omncane, angaxhunywa kalula kusokhethi kagesi noma ahlanganiswe nebhodi lokushintsha. Ukutshala imali ku-SPD kuyintengo encane okufanele uyikhokhele ukuvikelwa kwesikhathi eside ekunikezayo, okungenzeka kukusindise amakhulu noma ngisho nezinkulungwane zamaRandi uma kwenzeka ukwanda kwamandla.

    Uma ukhetha idivayisi yokuvikela ukukhuphuka, kubalulekile ukucabangela izici ezifana ne-voltage yokubopha, isikhathi sokuphendula, kanye nesilinganiso se-Joule. I-voltage yokubopha imelela izinga le-voltage lapho idivayisi idlulisela khona amandla amaningi. I-voltage ephansi yokubopha iqinisekisa ukuvikelwa okungcono. Isikhathi sokuphendula sibhekisela ekutheni idivayisi isabela ngokushesha kangakanani ekukhuphukeni, kuyilapho isilinganiso se-Joule sibonisa ikhono ledivayisi lokumunca amandla ngesikhathi sesehlakalo sokukhuphuka.

    Ekuphetheni, ukuthembela okwandayo emishinini kagesi kudinga izinyathelo ezisebenzayo zokuvikela ekukhuphukeni kwamandla. Imishini yokuvikela ukukhuphuka kwamandla iyindlela ebalulekile yokuzivikela ekuvimbeleni umonakalo ongaba yindleko emishinini yakho ye-elekthronikhi eyigugu. Ngokutshala imali ku-SPD, ungaba nokuthula kwengqondo kokuthi imishini yakho ngeke ithintwe ukukhuphuka kwamandla okungalindelekile futhi izohlala isikhathi eside. Thatha izinyathelo ezidingekayo zokuvikela imishini yakho ye-elekthronikhi ngokuvikela ukukhuphuka kwamandla namuhla.
