Kungani amabhokisi okusabalalisa kudingeka afakwe idivayisi yokuvikela ukukhuphuka?

Ezweni lanamuhla elithuthukile kwezobuchwepheshe, isidingoidivayisi yokuvikela ukukhuphuka (I-SPD) emabhokisini okusabalalisa akunakuthathelwa phansi. Izivikeli zokuqhuma zidlala indima ebalulekile ekuvikeleni imishini kagesi neye-elekthronikhi ekushayweni kombani kanye nomonakalo we-overvoltage. I-voltage ephezulu kanye nogesi okhiqizwa ngesikhathi sokuqhuma kombani, kanye nesikhathi esifushane sokukhululwa kwamandla, kuba usongo olukhulu ezintanjeni zikagesi, ezintanjeni zesignali, eziphakeli ze-antenna kanye namapayipi ensimbi. Lokhu kungaba nemiphumela emibi kakhulu ezinhlotsheni zikagesi neze-elekthronikhi kanye nezinhlelo zenethiwekhi yolwazi. I-voltage eseleyo kanye nombani wokungenisa okhiqizwa ukuqhuma kombani kungabangela amasekethe amafushane, ukusha, kanye nokuqhuma emishinini kagesi, okubangela ukulahlekelwa okukhulu. Ngakho-ke, kubalulekile ukufaka amadivayisi okuvikela ukuqhuma emabhokisini okusabalalisa ukuze kuncishiswe lezi zingozi futhi kuqinisekiswe ukuvikelwa kwemishini nezinhlelo ezibalulekile.

Ngesikhathi umbani ukhishwa, amandla akhishwayo makhulu futhi angahlasela ngqo noma ngokungaqondile izinhlelo ezahlukene ezibalulekile. Izinyathelo zokuvikela umbani zangaphandle njengezinduku zombani azanele ukuvala umonakalo ongaba khona obangelwa amaza ombani. Yilapho amadivayisi okuvikela ukukhuphuka kwamandla eqala ukusebenza khona. Aklanyelwe ngqo ukuvikela ekushayweni umbani nokuxazulula ama-overvoltage azwakalayo emigqeni yokusabalalisa ene-voltage ephansi. Isivikelo sokukhuphuka kwamandla elanga sidlulisela ngokushesha i-voltage ephezulu kanye nogesi omkhulu emhlabeni ngentambo yokuvikela umbani, sivikele ibhokisi lokusabalalisa ekushayweni umbani futhi sinciphise umthelela we-overvoltage. Ngakho-ke, ukufaka isivikelo sokukhuphuka kwamandla elanga ebhokisini lokusabalalisa kuyisilinganiso sokuvikela esibalulekile ohlelweni lokunikezwa kwamandla elanga oluphansi.

Ukubaluleka kwezivikeli zokukhuphuka kwamandla emabhokisini okusabalalisa akunakweqiswa, ikakhulukazi uma ubhekene nezinhlekelele zemvelo ezinzima njengokushaywa kombani. Umonakalo ongaba khona obangelwa ukushaywa kombani kanye nokwanda kwamandla kagesi kumasistimu enethiwekhi yolwazi kanye nemishini kagesi kugcizelela isidingo esiphuthumayo sezinyathelo zokuvikela ezisebenzayo. Ngokufaka izivikeli zokukhuphuka kwamandla emabhokisini okusabalalisa, unganciphisa kakhulu ingozi yomonakalo obangelwa ukushaywa kombani kanye nokwanda kwamandla kagesi, uqinisekise ukuphepha nokusebenza kwemishini nezinhlelo ezibalulekile.
