Indlela yokukhetha i-Thyristor Power Regulator?

Umlawuli wamandla we-Thyristorwamkela thyristor njengento yokutshintshela, nto leyo iswitshi non-contact enokulawulwa.Ineempawu zolawulo oluchanekileyo kunye nempembelelo encinci.Kubalulekile ukuba uqaphele ukuba ulawulo oluhlukeneyo lunokukhethwa ngokwemithwalo eyahlukeneyo kunye neendawo zokusebenza.Iindlela zokulawula eziqhelekileyo ziquka ukulawulwa kwe-angle yesigaba, ukulawulwa kwe-zero crossing, i-angle yesigaba + i-zero yokulawula ukuwela, njl.
Isilawuli samandla se-Thyristor sinokwahlulwa sibe sisilawuli samandla se-thyristor sesigaba esisodwa kunye nesigaba sesithathu solawulo lwamandla e-thyristor ngokohlobo lomthwalo, uhlobo lonikezelo lwamandla kunye nenqanaba lombane lombane.Okulandelayo, siza kwazisa iingxaki ezifuna ingqalelo ekukhetheni imveliso:

1. Xa amandla omthwalo omncinci kakhulu, isigaba esisodwa sisigqibo esihle kakhulu, esingayi kubangela ukungalingani kwesigaba sesithathu kwigridi yamandla.Xa usebenzisa umlawuli wesigaba esisodwa, qwalasela umthamo wesiphambano sesiphaluka kunye nomthamo wekhebula wesiphaluka sombane.Ukuze unciphise impembelelo yomlawuli kwigridi yamandla, zama ukusebenzisa i-380V.
2. Amandla omthwalo opheleleyo makhulu kwaye anokwahlulwa abe ngamaqela amaninzi omthwalo wesigaba esisodwa.Ngoko ke, kucetyiswa ukuba ukhethe abalawuli bamandla e-thyristor amacandelo amaninzi.Ekusetyenzisweni, umlawuli wamandla we-thyristor kunye nomthwalo usasazwa ngokulinganayo kunikezelo lwamandla amanqanaba amathathu.Inzuzo yale nto ayikho kuphela ukugcina ibhalansi yesigaba sesithathu, kodwa nokunciphisa umsebenzi wezixhobo zombane.
3. Umthwalo wokulawula amandla wesigaba sesithathu se-thyristor ngokubanzi uneendlela ezintathu zokudibanisa, uxhulumaniso lukanxantathu, uxhulumaniso lwenkwenkwezi olungathathi hlangothi lwe-zero, uxhulumaniso lweenkwenkwezi olungathathi hlangothi lwe-zero.Ulawulo lwamandla oluphezulu lwesigaba sesithathu se-thyristor ludinga ibha yobhedu okanye ikhebula kunye nommandla omkhulu onqamlezayo kunye neemeko ezilungileyo zokutshatyalaliswa kobushushu.
Nokuba ukhetha aumlawuli wamandla wesigaba esinyeokanye aumlawuli wamandla wesigaba sesithathu, kufuneka uqinisekise inqanaba lakho lombane, inqanaba langoku elifunekayo kunye nendlela yokulawula esetyenziswayo.Ekukhethweni kwayo nayiphi na ingxaki, siya kukubonelela ngenkonzo yobungcali.
