Ukuqonda imisebenzi kunye nokubaluleka kwabakhuseli botyando (SPDs)

Izixhobo ezikhuselayo ze-Surge(SPDs)dlala indima ebalulekileyo ekukhuseleni uthungelwano losasazo lwamandla ukusuka kwi-overvoltage kunye nee-surge currents.Ukukwazi kwe-SPD ukunciphisa i-overvoltages kuthungelwano losasazo ngokuguqula i-surge current ngoku kuxhomekeke kumacandelo okukhusela okutshatyalaliswa, ukwakheka komatshini we-SPD, kunye nokudibanisa kwinethiwekhi yokusabalalisa.I-SPDs ziyilelwe ukunciphisa umbane ogqithisayo kunye nokuguqula imisinga ye-inrush, okanye zombini.Iqulethe ubuncinane icandelo elinye elingenamgca.Ukubeka nje, ii-SPD zenzelwe ukunciphisa ukugqithisa okwethutyana ukuthintela umonakalo wesixhobo.

Ukubaluleka kwe-SPD akunakugqithiswa, ngakumbi kule mihla kunye neminyaka apho izixhobo ze-elektroniki ezibuthathaka zikho yonke indawo kwiindawo zokuhlala kunye nezorhwebo.Njengoko ukuthembela kwizixhobo ze-elektroniki kunye nezixhobo kusanda, umngcipheko womonakalo ovela kumandla ombane kunye nokugqithisa okwethutyana kuya kubaluleka ngakumbi.I-SPDs ngumgca wokuqala wokukhusela kulolu hlobo lokuphazamiseka kombane, ukuqinisekisa ukuba izixhobo ezixabisekileyo zikhuselwe kwaye zikhusela ixesha lokunciphisa ngenxa yomonakalo.

Imisebenzi yeSPD inamacala amaninzi.Ayikhawuleli kuphela ukugqithisa okugqithise okwexeshana ngokuphambukisa imisinga yokunyuka, kodwa ikwaqinisekisa ukuba uthungelwano losasazo lwamandla luhlala luzinzile kwaye luthembekile.Ngokuphambukisa imisinga yokunyuka, ii-SPDs zinceda ukuthintela uxinzelelo olunokukhokelela ekuqhekekeni kwe-insulation, ukonakala kwezixhobo kunye neengozi ezinokuthi zibekho zokhuseleko.Ukongeza, babonelela ngenqanaba lokhuselo lwezixhobo zombane ezibuthathaka ezinokuthi zibe sesichengeni sokuguquguquka okuncinci kwamandla ombane.

Amacandelo angaphakathi kweSPD adlala indima ebalulekileyo ekusebenzeni kwayo ngokubanzi.Amacandelo angenawo umgca wenzelwe ukukhusela izixhobo ezixhunyiwe ngokunika indlela ephantsi yokuthintela ukunyanzeliswa kwemisinga ukuze kuphendule ukugqithisa.Isakhiwo soomatshini seSPD sikwanegalelo ekusebenzeni kwayo, njengoko kufuneka ikwazi ukumelana namandla okwanda ngaphandle kokusilela.Ukongeza, uqhagamshelo kuthungelwano lokuhambisa amandla lubaluleke kakhulu, njengoko ukufakela okuchanekileyo kunye nokubekwa phantsi kubalulekile ekusebenzeni ngokufanelekileyo kweSPD.

Xa uqwalasela ukhetho kunye nokufakwa kwe-SPD, kubalulekile ukuvavanya iimfuno ezithile zenkqubo yombane kunye nezixhobo ezixhasayo.Ii-SPD zifumaneka kwiindidi ezahlukeneyo kunye nokucwangciswa, kubandakanywa udidi lwe-1, uhlobo lwe-2 kunye ne-Type 3 izixhobo, nganye ifanelekile kwizicelo ezahlukeneyo kunye neendawo zokufakela.Kunconywa ukubonisana nochwepheshe oqeqeshiweyo ukuqinisekisa ukuba i-SPD ikhethwe ngokufanelekileyo kwaye ifakwe ukubonelela ngenqanaba elifunekayo lokukhusela.

Isishwankathelo, izixhobo zokukhusela i-surge (SPDs) zidlala indima ebalulekileyo ekukhuseleni uthungelwano lokuhambisa amandla kunye nezixhobo ze-elektroniki ezinobuthathaka kwimiphumo eyonakalisayo yokugqithisa kunye nokunyuka kwangoku.Ukukwazi kwabo ukunciphisa i-overvoltages edlulayo kunye nokuguqula i-inrush currents kubalulekile ukugcina uzinzo kunye nokuthembeka kweenkqubo zombane.Njengoko izixhobo ze-elektroniki ziqhubeka zikhula, ukubaluleka kwe-SPD ekukhuseleni ukutshatyalaliswa kwamandla kunye nokugqithisa okwethutyana akukwazi ukujongelwa phantsi.Ukukhethwa ngokufanelekileyo, ukufakwa kunye nokugcinwa kwe-SPD kubalulekile ekuqinisekiseni ukukhuselwa okuqhubekayo kwezixhobo ezixabisekileyo kunye nokusebenza okungaphazamisekiyo kweenkqubo zombane.
