Idivayisi ye-TRS-A Surge Protection

Incazelo emfushane:

Uchungechunge lwe-TRSA lwedivayisi yokuvikela ukuhlinza luhlangabezana nezimfuneko ze-IEC61643 ejwayelekile yesibambisi sombani sesigaba sokuqala. Uma isetshenziswa nesibambisi sombani esinciphisa umbani wesigaba sokugcina, isibambisi sombani esinezigaba ezimbili singafakwa ndawonye. Ngenxa yesakhiwo esivalwe ngokuhlukile, ngeke kube khona i-arc yokuvuza ngisho nangesikhathi sokusebenza.

TRS-A SPD

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.

Idivayisi yokuvikela umbani yezinga lokuqala ingakhipha umbani oqondile wamanje, noma ikhiphe amandla amakhulu aqhutshwa lapho ulayini wokudlulisa amandla ushaywa umbani ngokuqondile. Ezindaweni lapho kungenzeka umbani oqondile, ukuvikela kombani kwe-CLASS-I kufanele kwenziwe.

Uchungechunge lwe-TRS-A yohlobo 1 lwe-SPD luyatholakala lunamandla amanje ashukumisayo angu-15kA, 25KA, 50KA ekucushweni kwesigaba esisodwa noma sesigaba esingu-3 kanye nama-voltage ahlukahlukene ukuze kuvikelwe noma yiluphi uhlobo lwesistimu yokuphakela amandla.

I-THOR Type 1 DIN-rail SPD izici zinikeza impendulo esheshayo eshisayo nomsebenzi ophelele wokunqamula futhi inikeza isivikelo esisheshayo nesithembekile sezinhlelo ezihlukahlukene zokuphakela amandla.Nomthamo wayo wokukhipha amandla amanje ngokuphephile nge-waveform engu-10/350 μs.
