Iyini i-phase angle angle control scr power regulator?

Amakhasimende amaningi abuza ukuthi yini isilawuli samandla se-phase angle scr?Namuhla sizokunikeza isingeniso.

Thatha uhlelo lwezigaba ezintathu njengesibonelo, njengoba sazi sonke.Esigabeni ngasinye, kunama-SCR amabili ahambisanayo.Ekulawulweni kwe-engeli yesigaba, i-SCR ngayinye yokubhangqa okubuyela emuva ivuliwe ngengxenye eguquguqukayo yomjikelezo oyingxenye ewuqhubayo.Amandla alawulwa ngokuthuthukisa noma ukubambezeleka kwendawo lapho i-SCR ivulwa khona phakathi komjikelezo ngamunye.Isignali ye-analog engu-4-20mA inquma indawo nosayizi we-engeli yokushintsha kwesigaba.Ngokulungisa isignali ye-analog, okukhiphayo kungalawulwa.

Ukulawulwa kwe-Phase-angle kunikeza ukulungiswa okuhle kakhulu kwamandla futhi kusetshenziselwa ukulawula imithwalo ephendula ngokushesha njengezibani ze-tungsten-filament noma imithwalo lapho ukumelana kushintsha khona njengomsebenzi wokushisa.Ekukhetheni umkhiqizo kufanele unake, uma umthwalo wakho uguquguqukayo noma i-transformer, kufanele usebenzise isilawuli se-engeli yesigaba, imodi yokuwela i-zero izoholela ohambweni lwamanje.

Izilawuli zamandla ze-scr zesigaba-engelingokuvamile zibiza kakhulu kunezilawuli ze-zero-cross ngoba isekethe ye-engeli yesigaba idinga ubunkimbinkimbi kunomjikelezo oyiziro-cross.Ukuze kuhlangatshezwane nezidingo zamakhasimende ku-isilawuli samandla, imikhiqizo yesilawuli samandla enkampani yethu ongasetha ukuze ulawule isigaba noma ulawule uziro, kulula kakhulu.Ingasetshenziswa ezimweni ezihlukahlukene zomthwalo.

Inzuzo yokulawula i-engeli yesigaba ukuthi ukunemba kokulawula kuphezulu, futhi okukhiphayo kwesilawuli samandla kukhuphuka kancane kancane ngokuya ngevelu enikeziwe kuze kube ivelu emisiwe.Ingakha isistimu yokulawula iluphu evaliwe enesignali yamanje, isignali ye-voltage, isignali yezinga lokushisa, njll. Ngokulawulwa kwe-PID, lonke uhlelo lokulawula luzinzile futhi luthembekile.

Ukulawula i-engeli yesigaba kanye nokulawula ukuwela u-zero izindlela ezimbili ezihlukene zokulawulascr amandla abalawuli, banezimo zabo zohlelo lokusebenza ezahlukene.Awukwazi ukumane usho ukuthi iyiphi indlela engcono, ingasho kuphela ukuthi izinhlelo zokusebenza ezahlukene zidinga izilawuli ezahlukene.
