Idivayisi ye-TRS-C Surge Protection

Incazelo emfushane:

Uchungechunge lwe-TRSC lwezivikeli zokuhlinza amandla ezimodulayo luklanywe ngokuvumelana namazinga e-IEC ne-GB, futhi uchungechunge lwe-TRS lwabavikeli bokuhlinzwa (kamuva olubizwa ngokuthi SPD) lufanele i-AC 50/60Hz, 380V ne-TT, TN-C, TN-S, I-IT kanye nezinye izinhlelo zokuphakela amandla, zombani ongaqondile noma ithonya lombani oqondile noma okunye ukuvikela okungaphezu kwamandla. Igobolondo lalo mkhiqizo lidizayinelwe ukuthi lifakwe kumareyili kagesi angu-35mm, nedivayisi eyakhelwe ngaphakathi yokukhulula ukwehluleka, lapho isivikelo sombani sihluleka ngenxa yokudlula i-current, ukushisa ngokweqile, nokuwohloka, Idivayisi yokungaphumeleli yokunqamula ingayinqamula ngokuzenzakalelayo kugridi yamandla. , futhi inkomba ye-alamu ebonakalayo iyashintsha isuke kokuluhlaza (evamile) iye kokubomvu (inephutha).Imojula yokuvikela ingashintshwa uma kunogesi osebenzayo.

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.

I-TRS-B,C,D yochungechunge lwe-2 SPDs iyatholakala inamandla 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 eshisayo esheshayo nomsebenzi wokunqamula ophelele futhi zinikeza ukuvikeleka okusheshayo nokuthembekile kwezinhlelo ezihlukahlukene zokuphakela amandla. Kanye nekhono layo lokukhipha 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.
