Yintoni isigaba solawulo lwe-engile scr umlawuli wamandla?

Abathengi abaninzi ngakumbi bayabuza malunga nokuba yintoni i-angle angle control scr power regulator?Namhlanje siza kukunika intshayelelo.

Thatha inkqubo yezigaba ezithathu njengomzekelo, njengoko sonke sisazi.Kwinqanaba ngalinye, kukho ii-SCR ezimbini ngokufanayo.Kulawulo lwe-angle-angle, i-SCR nganye ye-back-to-back pair ivuliwe kwisahlulo esiguquguqukayo somjikelezo wesiqingatha osiqhubayo.Amandla alawulwa ngokuqhubela phambili okanye ukulibazisa indawo apho i-SCR ivuliwe ngaphakathi komjikelo wesiqingatha ngasinye.I-4-20mA isignali ye-analog inquma indawo kunye nobukhulu be-angle shift shift.Ngokulungelelanisa umqondiso we-analog, imveliso inokulawulwa.

Ulawulo lwe-angle-angle lubonelela ngesisombululo esihle kakhulu samandla kwaye sisetyenziselwa ukulawula imithwalo yokuphendula ngokukhawuleza njengezibane ze-tungsten-filament okanye imithwalo apho ukuchasana kuguquka njengomsebenzi wokushisa.Kukhetho lwemveliso kufuneka uhlawule ingqalelo, ukuba umthwalo wakho u-inductive okanye i-transformer, ngoko kufuneka usebenzise ulawulo lwe-angle yesigaba, imodi yokuwela i-zero iya kukhokelela kuhambo lwangoku.

Isigaba-engile scr amandla abalawulizidla ngokubiza kakhulu kunezero-cross regulators ngenxa yokuba i-phase-angle circuit ifuna ubugocigoci obungaphezulu kune-zero-cross circuit.Ukuze kuhlangatyezwane neemfuno zabathengi kwiumlawuli wamandla, iimveliso zolawulo lwamandla enkampani yethu onokuthi uzibeke kulawulo lwesigaba okanye ulawulo lwe-zero, lulunge kakhulu.Ingasetyenziswa kwiimeko ezahlukeneyo zomthwalo.

Inzuzo yokulawulwa kwe-angle yesigaba kukuba ukuchaneka kokulawula kuphezulu, kwaye imveliso yomlawuli wamandla ikhula ngokukhawuleza kwaye ngokukhawuleza ngokwexabiso elinikeziweyo kude kube yixabiso elimiselweyo.Inokwenza inkqubo yokulawula i-loop evaliweyo kunye nesignali yangoku, umqondiso we-voltage, umqondiso weqondo lokushisa, njl. Ngokusebenzisa ulawulo lwe-PID, yonke inkqubo yokulawula izinzile kwaye inokwethenjelwa.

Ulawulo lwe-engile yeSigaba kunye nolawulo lokuwela zero ziindlela ezimbini ezahlukeneyo zokulawulascr amandla abalawuli, baneemeko zabo ezahlukeneyo zesicelo.Awunakutsho ngokulula ukuba yeyiphi na indlela engcono, inokuthi kuphela usetyenziso olwahlukileyo lufuna ulawulo olwahlukileyo.
