Idivayisi ye-TRS9 Surge Protection

Incazelo emfushane:

Idivayisi yokuvikela uchungechunge lwe-TRS9 (ngemuva kwalokhu ebizwa ngokuthi i-SPD) ilungele i-AC 50/60HZ, i-voltage elinganiselwe ukuya ku-380v LT, TT, TN-C, TN-S, TN-C-S nolunye uhlelo lokuphakelwa kwamandla, ivikela ngokungaqondile futhi ukukhanyisa okuqondile noma okunye okudlulayo phezu komklamo we-voltageSPD ngokuya nge-GB18802.1/IEC61643-1 ejwayelekile.

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 okuphumayo noma umfutho wamanje odalwe yi-overvoltage emhlabeni/emhlabathini, ngaleyo ndlela kuvikelwe okokusebenza ezansi nomfula. Ama-SPD afakwe ngokuhambisana nolayini kagesi okufanele avikelwe. 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-TRS9 uhlobo 2 SPDs luyatholakala lunamandla okukhipha angu-80kA, 100KA, 120KA, 150KA ekucushweni kwesigaba esisodwa noma sesigaba esingu-3 kanye nama-voltage ahlukahlukene ukuze kuvikelwe noma yiluphi uhlobo lwesistimu yokuphakela amandla. 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.
