Vikela imishini kagesi, uqale ngomvikeli wokuhlinzwa we-SPD!

Isingeniso

Umvikeli wokuhlinzwa we-SPDiwuhlobo olusha lomkhiqizo wokuvikela umbani owenziwe ngesivikelo sokuhlinza kanye nesekethe ye-elekthronikhi, esetshenziswa kakhulu ukuvikela izinto zikagesi ekushayweni kombani nombani.Umgomo osebenzayo wesivikeli sokuhlinza se-SPD ukukhawulela umbani wamanje nge-SPD uye ebangeni elithile ngokusebenzisa ishubhu elinciphisa amandla kagesi kanye ne-diode ku.I-SPD.

Izici zeAbavikeli bokuhlinzwa be-SPD:

1, Ukunciphisa umbani wokushaywa kwamanje (okubuye kubizwe ngokuthi ukukhishwa kombani wamanje);

2, Ukunciphisa umbani we-pulse voltage (okungukuthi ukukhipha i-voltage);

3, I-Electromagnetic Pulse (EMI) eneSivimbo Sombani Esikhawulelwe;

4, Ukunciphisa amandla akhiqizwa umbani;

5, Ukuvikela into emonakalweni obangelwa ukushaywa kombani oqondile noma ukuphazamiseka kukazibuthe;

6, Ukukhawulela i-over-voltage eyengelwe kusekethe (i-voltage yokungeniswa kombani noma i-over-voltage eyengelwe).

Ububanzi Besicelo

Umvikeli we-SPD ohlinzayo uyavikelaokokusebenza kukagesi kusuka ekuphakameni kombani nokunye ukugcwala ngokweqile kanye nokudlula ngokweqile ohlelweni lwamandla.Ingavikela imishini kagesi ekukhuphukeni ngokweqile futhi iqinisekise ukuphepha komuntu siqu.

I-SPD Surge Protectors isebenza kulezi zindawo ezilandelayo:

(1) Indawo yokufaka ugesi yezakhiwo eziphakeme;(2) I-inlet yezintambo ze-optical zokuxhumana kanye nezintambo zesignali emigqeni yokuphakelwa kukagesi;(3) I-inlet yamabhokisi okusabalalisa namakhabethe;(4) I-inlet yama-cable cores nezintambo ezingaphezulu;(5) Indawo yokufaka ugesi yamasistimu ekhompyutha;futhi (6) Indawo yokungena yezinto ezishintshayo ezakhiweni izohlonyiswa ngezivikeli ezikhuphukayo ze-SPD uma okokusebenza okushintshwayo kunikwe amandla okuphakela kukagesi we-AC, kuyilapho indawo yokungena kagesi we-AC izofakelwe izivikeli zokuhlinza ze-SPD.

Inkomba yokusebenza

I-1, Uma isibambi se-SPD sisebenza ngokujwayelekile, akumele kube khona ukuthintana okubi, ngaphezu kwe-voltage noma ngaphansi kwe-voltage.

2, Uma isibambi sokuhlinza se-SPD sisebenza okuvamile, akukho mfutho omkhulu wamanje odlula kumshini wokuhlinza.

3, Umthamo wamanje wesibophi se-SPD akufanele ube ngaphansi kwezikhathi ezingu-1.2 zomthamo wamanje olinganiselwe wezinto ezivikelwe, futhi akumele ube ngaphansi kuka-1000A (noma i-voltage elinganiselwe ngeke ibe ngaphansi kuka-10/350V);uma umthamo wamanje wezinto ezivikelwe ungaphezu kuka-10/350V, sicela usithinte ukuze ukhethe umthamo wamanje ofanele phakathi kwebanga eliphephile nelisebenzayo.
