Umlawuli wamandla we-GS40 we-oven scr

Uluhlu lwabalawuli bamandla be-GS40ziyilelwe ukulinganisa amandla ombane axhathisekunye ne-inductiveimithwalo, njengee-oveni, iziko,ii-transformer,abatywini bobushushu, njl.Umlawuli wamandla wamkela i-4 ukuya kwi-20 mA dc ephuma kumlawuli weqondo lokushisa okanye unokubonelelwa ngenketho ye-manual usebenzisa i-potentiometer ekude.

Abalawuli be-GS40 Series banikezela ngeendlela ezimbini zokulawula ukulingana: i-Zero crossing switched kunye ne-Phase angled fired.

Ngemo yokutshintsha kweZero, umlawuli utshintshela kwimijikelo epheleleyo yombane we-ac.Isekethe ye-trigger yenzelwe ukuvula ii-SCRs ngokusondeleyo kangangoko kunokwenzeka ukuya kwindawo apho i-AC sine wave inqumla nge-zero.Enyanisweni, i-voltage yomgca ivuliwe kwaye ivaliwe kwaye isetyenziswe kwii-heaters kwimijikelezo epheleleyo.Ngegalelo le-4 ukuya kwi-20 mA, imveliso iya kuba phantsi kwe-4 mA kwaye igcwele kwi-20 mA.

Inyathelo lokulinganisa lifunyanwa ngokutshintsha inani lemijikelo ukuya kwinani lemijikelo ephumileyo.Isiphumo siya kwahluka ukusuka kumjikelo omnye ukuya kwimijikelo elithoba kwigalelo eliphantsi, ukuya kuyo yonke imijikelo ngokowona mkhulu.Le mveliso idityaniswe ngabafudumezi abavelisa ubushushu obulungelelanisiweyo obuguquguqukayo ngokuthe ngqo kunye nomqondiso wokungenisa.Kule ndlela yokulawula, i-waveform ye-voltage ephumayo yi-sine wave ecocekileyo, ke akufuneki ube nexhala malunga nesizukulwana se-harmonic.

Ngemo yeSigaba sokudubula i-angle, amandla kumthwalo alawulwa ngokulawula indawo yokuvula (ukudubula) kwisiqingatha ngasinye somjikelezo we-AC sine wave epheleleyo.Kule ndlela yokulawula, i-waveform ye-voltage ephumayo ayikho into ecocekileyo. i-sine wave, kunye negalelo le-4-20mA yesiginali, i-voltage chopper ephumayo, iya kuvelisa inani elithile le-harmonics, xa imveliso yamandla egcweleyo, imveliso iya kuba yi-sine wave.

Iimpawu zeIzilawuli zamandla ze-GS40 scrnjengoko kungezantsi:

I-1.I-microcontroller eyakhelwe ngaphakathi yokusebenza ephezulu.

2.Uyilo lokusetyenziswa kwamandla aphantsi.

3.Igalelo lombane obanzi obanzi (AC110–440V).

I-4.Uyilo oluncinci, umlinganiselo omncinci.

5.Inkxaso ye-4-20mA,0-10v igalelo le-analogue.

I-6.Ukukhuselwa okugqibeleleyo: Isigaba silahlekelwa, sigqithise, sigqithise, silahlekelwe ngumthwalo.

Unxibelelwano lwe-7.Modbus.
