Idivayisi ye-TRS4 Surge Protection

Incazelo emfushane:

Umgomo wokusebenza wedivayisi yokuvikela ukuhlinza: Izibambisi zokuhlinza ezivame ukuchazwa ngokuthi ama-SPD (Amadivayisi Okuvikela Ukuhlinza), zingamadivayisi aklanyelwe ukuvikela amasistimu kagesi nezisetshenziswa ekuvimbeleni ukuqhuma okudlulayo nokunamandla njengalokho okubangelwa ukushaywa kombani kanye nokushintshwa kukagesi. Umsebenzi wabo ukuphambukisa ukukhishwa noma umfutho wamanje owenziwe yi-overvoltage emhlabeni/emhlabathini, ngaleyo ndlela kuvikelwe okokusebenza phansi komfula.Ama-SPD afakwe ngokuhambisana nogesi...

Umgomo wokusebenza wedivayisi yokuvikela ukuhlinza: Izibambisi ezihlinzayo ezivame ukuchazwa ngokuthi ama-SPD (Amadivayisi Okuvikela Ukuhlinza), zingamadivayisi aklanyelwe ukuvikela amasistimu kagesi nezinto zokusebenza ngokumelene nokuqhuma kwesikhashana nokudlulele okufana nalokhu okubangelwa umbani kanye nokushintshwa kukagesi. Umsebenzi wabo ukuphambukisa ukukhishwa noma umfutho wamanje owenziwe yi-overvoltage emhlabeni/emhlabathini, ngaleyo ndlela kuvikelwe okokusebenza phansi komfula.Ama-SPD afakwe ngokuhambisana nentambo kagesi okufanele ivikelwe. Ku-voltage elinganiselwe yama-mains, aqhathaniswa nesekethe evulekile futhi ane-impedance ephezulu ekugcineni kwawo. Lapho kukhona i-overvoltage, le impedance iwela kumanani aphansi kakhulu, ukuvala isekethe emhlabeni/emhlabathini. Uma i-overvoltage isiphelile, i-impedance yabo ikhuphuka futhi ngokushesha kunani lokuqala (eliphezulu kakhulu), libuyela ezimeni ezivulekile ze-loop. I-Type 2 SPD iwuhlelo oluyinhloko lokuvikela kukho konke ukufakwa kukagesi wamandla aphansi. Ifakwe ebhodini lokushintshwa likagesi ngalinye, ivimbela ukusabalala kwama-overvoltages ekufakweni kukagesi futhi ivikela imithwalo. Amadivayisi okuvikela ohlobo lwe-2 (ama-SPD) aklanyelwe ukuvikela ukufakwa kukagesi nezisetshenziswa ezizwelayo ekuhlinzeni okungaqondile kanye nokuqinisekisa ileveli yokuvikela ephansi (Phezulu). Imishini yokuvikela yohlobo 2 yokuhlinza inikeza isivikelo esisebenzayo kulokhu okuguquguqukayo kokuphazamiseka. Kungakhathaliseki ukuthi kusendaweni yezimboni noma esakhiweni sokuhlala, ukuvikelwa kohlobo 2 kuqinisekisa ukuvikeleka okuyisisekelo kokufaka kwakho namadivayisi. Uchungechunge lwe-TRS4 lohlobo 2 SPDs luyatholakala lunamandla okukhipha angu-10kA, 20KA, 40KA, 60KA ekucushweni kwesigaba esisodwa noma sesigaba esingu-3 kanye nama-voltage ahlukahlukene ukuze kuvikelwe noma yiluphi uhlobo lwesistimu yokuphakelwa kwamandla. Izici ze-THOR Type 2 DIN-rail SPD zinikeza impendulo esheshayo eshisayo nomsebenzi ophelele wokunqamula futhi zinikeza ukuvikelwa okusheshayo nokuthembekile kwezinhlelo ezihlukahlukene zokuphakela amandla.Nomthamo wayo wokukhipha amandla amanje ngokuphephile nge-waveform engu-8/20 μs. Yakhelwe ngesibonakaliso sephutha lewindi kanye nokuxhumana kwe-alamu okukude ngokuzikhethela, ingaqapha isimo sokusebenza se-SPD ngokwayo.
