Indlela yokubuyisela kunye nokulungelelanisa i ubushushu obuphezulu kwiziko lombane thyristor?

Ukutshintshwa Ukutshintsha iyunithi ye-thyristor, qale uhlukanise isithando sombane esinobushushu obuphezulu kunikezelo lwamandla, uze ususe isiciko secala lasekhohlo (0). Rekhoda zonke iidibansi kwi-thyristor, uze uyikhuphe. Buyisela isixhobo, kwaye emva koko uxhume kwakhona.

Qaphela: Ukuba utshintsha umbane we-208V, kufuneka ubuyisele iyunithi ye-thyristor.

Ukuba iyunithi ye-thyristor ithathelwe indawo ngenxa yokutshintsha kwe-voltage, ukulungiswa kwempompo ye-transformer echanekileyo kufuneka kumiselwe. Emva kokutshintsha nayiphi na iyunithi ye-thyristor, okanye emva kokutshintsha i-voltage okanye i-transformer tap, i-potentiometer kwi-thyristor kufuneka ihlengahlengiswe ukuze inike amacandelo achanekileyo ngoku. Lo msebenzi kufuneka wenziwe ngabasebenzi abaqeqeshiweyo, kuba kukho amandla ombane ayingozi kwigumbi lokulawula.

Ukongeza, i-ammeter ye-clamp ye-calibrated non-intrusive iyafuneka. Ngaphambi kokudibanisa ukunikezelwa kwamandla, vula i-potentiometer kwi-thyristor ukuya ngakwesobunxele (i-counterclockwise). Oku kucwangcisa imveliso yangoku ye-thyristor ukuba “yicime”. Xhuma umbane xa uvala isiciko esisecaleni. Lumka! Misela ubushushu bomlilo kwixabiso elikhulu. Vumela isitovu siqalise ukufudumala. Ukulinganisa umsinga ngokusebenzisa isiphaluka secandelo. Xa ulinganisa, sebenzisa iperi eshinyeneyo yeentambo kwicala lasekhohlo le-transformer ukuvunguza i-ammeter yokubamba. Lungisa i-potentiometer ebekwe phezu kwendawo yeyunithi ye-thyristor. Kancinci ulungelelanisa ekunene (ukuhamba kwewotshi) ukwandisa okwangoku, kwaye unqumame ukwenza i-ammeter iphendule.

Qhubeka ukulungelelanisa ukuze ukufunda ammeter phakathi (149 ukuba 150 A-for HTF 17) okanye (139 ukuba 140A-for HTF 18). Olu lungelelaniso kufuneka lwenziwe kwimizuzu emi-5 yokuqala yokufudumeza, kwaye uvavanyo lokugqibela kufuneka lwenziwe xa ubushushu besithando somlilo sombane sisezantsi kunobushushu obuphezulu malunga ne-100 ° C. Ukuba kuyimfuneko, qhubeka ulungelelanisa phantsi kwesi simo sokushisa. Nqamula unikezelo lwamandla kwaye uqinisekise ukuba ubuyisela indawo yolawulo esecaleni.
