Yintoni umkhuseli wokuqhafaza? Umkhuseli wotyando, okwabizwa ngokuba ngumkhuseli wombane, sisixhobo sombane esibonelela ukhuseleko lokhuseleko lwezixhobo ezahlukeneyo zombane, izixhobo, kunye nemigca yonxibelelwano. Xa i-spike yangoku okanye i-voltage ivele ngokukhawuleza kwisekethe yombane okanye isiphaluka sonxibelelwano ngenxa yokuphazamiseka kwangaphandle, umkhuseli wokunyuka unokuqhuba kwaye shunt ngexesha elifutshane kakhulu, ukuze uthintele ukuqhuma ekonakalisa ezinye izixhobo kwi isiphaluka. Kutheni sifuna umkhuseli wotyando? Iintlekele zemibane yenye yeentlekele zemvelo eziyingozi kakhulu. Nyaka ngamnye, kukho iingxwelerha ezingenakubalwa kunye nelahleko yepropathi ebangelwa yintlekele yombane kwihlabathi. Nge usetyenziso olukhulu lwezixhobo ezidibeneyo zombane kunye ne-microelectronic, apho ziya ngakumbi nangakumbi umonakalo kwiinkqubo kunye nezixhobo ezibangelwa overvoltages umbane kunye umbane we-electromagnetic pulses. Ngoko ke, kubaluleke kakhulu ukusombulula umbane iingxaki zokukhuselwa kweentlekele zezakhiwo kunye neenkqubo zolwazi lwe-elektroniki ngokukhawuleza kunokwenzeka. Ngeemfuno ezingqongqo zezixhobo ezinxulumeneyo zokukhusela umbane, ukufakwa kwezikhuseli zotyando ukucinezela i-surge kunye no-overvoltage kwangoko umgca, kunye ne-overcurrent kumgca wokukhupha uye waba yinxalenye ebalulekileyo yanamhlanje iteknoloji yokukhusela umbane. Usebenza njani umkhuseli wotyando? Umgaqo osebenzayo wemveliso yethu kukuba: xa kungekho overvoltage, imveliso ingaphakathi i-off state, kwaye ukuxhathisa akunasiphelo. Xa kukho overvoltage kwinkqubo, i imveliso ikwimeko evaliweyo kwaye ukuxhathisa kuncinci ngokungenasiphelo, kunye nengaphakathi Amacandelo aya kubamba i-voltage ngaphakathi koluhlu oluthile. , Umsinga oqukuqela kwi umgca uya kutsalwa kwaye ukhululwe. Emva kokuba ukukhutshwa kugqityiwe, imveliso ibuya kwimo ephezulu yokuchasa (ilizwe eliqhawulwe) ukuze lingabi nezinye iziphumo kwi izixhobo. Ziziphi iiparamitha ezibalulekileyo zomkhuseli wokutyanda? 1.Ubukhulu bombane obusebenzayo (Uc): Ibhekisa kwelona xabiso lisebenzayo le-AC Umbane wombane okanye i-DC enokuthi isetyenziswe ngokuqhubekayo kwi-SPD. I-2.Max yokukhupha yangoku (Imax):Ibhekisa kubuninzi bokukhupha okwangoku iSPD inakho. ukumelana kanye usebenzisa i-8/20μs igagasi langoku ukuchaphazela iSPD. 3.I-Minimun discharge current (In):Ibhekisa kwi-dicharge current apho iSPD inokusebenza khona. ngokwesiqhelo 4.Inqanaba lokhuseleko: Ixabiso eliphezulu lombane phakathi kwe-terminals ye-SPD kwi ubukho be-impulsive overvoltage.lt yiparameter esisiseko ukukhetha ngokuchanekileyo i SPD; i-akhawunti yayo kufuneka ithathwe ngokunxulumene nombane we-impulse wesixhobo esiya kuba ekhuselweyo. Wenza ntoni uTHOR? Ukusukela ekusekweni kwayo, iThor ibithobela umbane wamazwe ngamazwe umgangatho wokhuseleko (IEC61643-1) kwaye uzibophelele kwimveliso kunye nophando kunye uphuhliso lwezikhuseli zotyando. Iimveliso ziquka izikhuseli zombane wendlu, Abakhuseli be-photovoltaic surge, abakhuseli botyando kwimizi-mveliso, kunye nabakhuseli botyando lwenethiwekhi, umqondiso wokukhusela umbane, njl.njl ukubonelela abathengi ngeendlela ezingcono zombane iimveliso zokhuseleko.
