Uhlalutyo lwe-Thyristor Ukutshintsha iSekethe kwi-Medium Frequency Inverter Spot Welding Machine

I-thyristor switching circuit idlala indima ebalulekileyo ekusebenzeni kwe-medium frequency inverter spot welding machine. Iququzelela ukulawulwa kunye nokulawulwa kwamandla ombane, okwenza ukuba iinkqubo ze-welding ezichanekileyo nezisebenzayo. Kweli nqaku, siya kunika uhlalutyo olunzulu lwesekethe yokutshintsha i-thyristor kumatshini we-welding we-medium frequency inverter.

1. Isakhiwo esiSiseko seSekethe yokuTshintsha i-Thyristor: I-thyristor switching circuit iqulethe izinto ezininzi eziphambili, ezibandakanya i-thyristors (eyaziwa ngokuba yi-silicon-controlled rectifiers), iisekethe zokulawula isango, iisekethe ze-trigger, kunye nezixhobo zokukhusela. Ezi zixhobo zisebenza kunye ukulawula ukuhamba kombane kunye nokuqinisekisa ukusebenza okukhuselekileyo nokuthembekileyo komatshini we-welding.
2. Umsebenzi wee-Thyristors: I-Thyristors zizixhobo ze-semiconductor ezisebenza njengezitshixo ezilawulwa ngombane. Bavumela i-current ukuba ihambe kwicala elinye xa iqhutywe, kwaye xa iqhuba, ihlala iqhuba kude kube ngoku ihla phantsi komda othile. Kwisekethe yokutshintsha, i-thyristors isetyenziselwa ukulawula ukunikezelwa kwamandla kwi-welding transformer.
3. Iisekethe zokulawula isango: Iisekethe zokulawula isango zijongene nokubangela i-thyristors kunye nokulawula isenzo sabo sokutshintsha. Bavelisa imiqondiso yesango echanekileyo kunye nexesha eqalisa ukuqhutyelwa kwe-thyristors. Iisekethe zokulawula isango zenzelwe ukuqinisekisa ulungelelwaniso oluchanekileyo kunye nokulungelelaniswa kwenkqubo yokutshintsha i-thyristor.
4. Iisekethe ze-Trigger: Iisekethe ze-trigger zibonelela ngeempawu ezifunekayo zokuqalisa kwiisekethe zokulawula isango. Ezi zibonakaliso zenziwa ngokusekwe kwiiparamitha ezifunwayo ze-welding, ezifana ne-welding yangoku, ixesha le-welding, kunye ne-electrode force. Iisekethe ze-trigger ziqinisekisa ukuba i-thyristors iqhutywe ngexesha elifanelekileyo ukufezekisa iimpawu ze-welding ezifunwayo.
5. Izixhobo zokukhusela: Ukuqinisekisa ukhuseleko lomatshini we-welding kunye nokukhusela umonakalo kumacandelo, izixhobo zokukhusela zifakwe kwi-thyristor switching circuit. Ezi zixhobo ziquka ukhuseleko olugqithisiweyo, ukukhuselwa kwe-overvoltage, kunye nokubeka iliso lobushushu. Bafumanisa kwaye baphendule kwiimeko ezingaqhelekanga, ezifana nokugqithiswa kwangoku okanye i-voltage, kwaye bavule amanyathelo okukhusela ukukhusela inkqubo okanye umonakalo.
6. Ukulawula kunye nokuLawulwa kwamandla: I-thyristor switching circuit yenza ulawulo oluchanekileyo kunye nokulawulwa kwamandla kumatshini we-welding welding ophakathi. Ngokuhlengahlengisa iimpawu ezibangelayo kunye neesekethe zokulawula isango, amandla anikezelwe kwi-welding transformer anokuguqulwa ukuze afezekise iimpawu ezifunwayo ze-welding, njengamandla e-weld, ukungena, kunye nokufaka ukushisa.

I-thyristor switching circuit kumatshini we-welding we-medium frequency inverter iyinxalenye ebalulekileyo eyenza ulawulo oluchanekileyo kunye nokulawulwa kwamandla ombane. Ngokulungelelaniswa kwe-thyristors, iisekethe zokulawula isango, iisekethe zokubangela, kunye nezixhobo zokukhusela, umatshini we-welding unokuhambisa iinkqubo ezichanekileyo kunye nezisebenzayo. Uhlalutyo lwesiphaluka sokutshintsha i-thyristor sinika ingqiqo kwisakhiwo sayo esisisiseko kunye nokusebenza, kugxininisa ukubaluleka kwayo ekufezekiseni i-welds ephezulu kunye nokuqinisekisa ukusebenza ngokukhuselekileyo komatshini we-welding.
