Indima yomvikeli ohlinzayo

I-Surge, (Idivayisi Yokuvikela Ukuhlinza) iyithuluzi elibalulekile ekuvikelweni kombani kwezinto zikagesi.Umsebenzi wesivikeli sokuhlinza ukukhawulela ukugcwala ngamandla okungaphezu kwalokho okungena entanjeni yamandla kanye nolayini wokudlulisa isignali ngaphakathi kwebanga lamandla kagesi imishini noma isistimu engakwazi ukumelana nayo, noma ukukhipha amandla ombani anamandla emhlabathini ukuze kuvikelwe amathuluzi noma uhlelo oluvikelekile. ekulimaleni.ilinyazwe umthelela.

Isimiso somvikeli we-Surge

Umgomo wokusebenza wesivikeli sokuhlinza umi kanje: isivikelo sokuhlinza ngokuvamile sifakwa kuzo zombili iziphetho zedivayisi evikelwe futhi sisekelwe phansi.Ngaphansi kwezimo ezijwayelekile zokusebenza, umvikeli ohlinzayo uveza ukuvinjelwa okuphezulu ku-voltage yemvamisa yamandla evamile, futhi cishe akukho okwamanje okugeleza kuyo, okulingana nesekethe evulekile;lapho kwenzeka i-overvoltage yesikhashana ohlelweni, isivikeli sokuhlinza sizophendula ku-overvoltage yesikhashana ephezulu.I-voltage iveza ukuthintana okuphansi, okulingana nokujikeleza isikhashana okokusebenza okuvikelwe.

1. Uhlobo lokushintsha: Isimiso sayo sokusebenza siwukuthi lapho kungekho overvoltage esheshayo, iveza i-impedance ephezulu, kodwa uma isabela ekuvukeni kombani ngokushesha, ukuvimbela kwayo kushintsha kungazelelwe kube inani eliphansi, okuvumela umbani ukuba udlule.Uma isetshenziswa njengamadivayisi anjalo, amadivaysi afaka phakathi: izikhala zokukhishwa, amashubhu okukhipha igesi, i-thyristors, njll.

2. Uhlobo lwe-voltage-limiting: Isimiso sayo sokusebenza siwukuthi i-impedance ephezulu uma kungekho overvoltage esheshayo, kodwa i-impedance yayo izoqhubeka nokwehla ngokunyuka kwamandla okushisa amanje kanye ne-voltage, futhi isici sayo samanje se-voltage asiyona into eqondile.Amadivayisi asetshenziswa kumadivayisi anjalo: zinc oxide, varistor, suppressor diode, avalanche diode, njll.

3. Uhlobo lwe-Shunt noma uhlobo lokuminyanisa

Uhlobo lwe-shunt: ngokuhambisana nezinto ezivikelwe, luveza ukuthintana okuphansi kokushaya kombani kanye nokuphazamiseka okuphezulu kumaza okusebenza ajwayelekile.

Uhlobo lwe-Choke: Ochungechungeni olunezinto ezivikelwe, luveza ukuthintana okuphezulu kokushaya kombani kanye nokuphazamiseka okuphansi kumaza okusebenza ajwayelekile.

Amadivayisi asetshenziswa njengalawa madivayisi ahlanganisa: amakhoyili amakhoyili, izihlungi zephasi ephezulu, izihlungi ezidlula kancane, ama-wavelength short-circuiters angu-1/4, nokunye okunjalo.
