Ukuqonda isethi epheleleyo yeekhoyili zokucinezelwa kwe-arc

Inqanaba lilawulwaI-arc suppression coils, eyaziwa ngokuba "yi-high short-circuit impedance type", zizinto eziphambili kuthungelwano lokuhambisa amandla.Umoya wayo ophambili uqhagamshelwe kwindawo engathathi hlangothi yenethiwekhi yokusabalalisanjengomsebenzi ojikelezayo.Umgaqo wolwakhiwo wesixhobo kukujikeleza i-thyristors ezimbini ezibuyela umva ezidityanisiweyo, kunye ne-second winding esebenza njenge-winging control.Ngokulungelelanisa i-angle conduction ye-thyristor, i-short-circuit current ye-second winding inokulawulwa, ngaloo ndlela ilungisa ixabiso lokuphendula.

Enye yeempawu eziphambili zeekhoyili zokucinezelwa kwe-arc kukulawulwa kwazo.I-angle conduction ye-thyristor inokuhluka ukusuka kwi-0 ° ukuya kwi-180 °, ibangela ukuba i-impedance elinganayo ihluke kwi-infinity ukuya kwi-zero.Oku kulandelana kuvumela imbuyekezo yesiphumo yangoku ukuba iqhubeke kwaye ihlengahlengiswe ngaphandle kwenyathelo phakathi kwe-zero kunye nexabiso elilinganisiweyo.

Eli nqanaba lolawulo libalulekile ekulawuleni uthungelwano losasazo njengoko livumela abaqhubi ukuba bahlengahlengise amaxabiso okusabela kwiimfuno ezithile.Ngokulungelelanisa i-angle conduction ye-thyristor, i-coil yokunciphisa i-arc elawulwa yisigaba inokunciphisa ngokufanelekileyo impembelelo ye-short-circuit current kwaye iqinisekise ukuzinza nokuthembeka kwenethiwekhi yokusabalalisa.

Kwizicelo eziphathekayo, iikhoyili zokunciphisa i-arc ezilawulwa yisigaba zidlala indima ebalulekileyo ekuphuculeni ukusebenza ngokubanzi kweenkqubo zombane.Ukukwazi kwayo ukubonelela ngolawulo olulawulwayo lwexabiso lokusabela kuyenza ibe yi-asethi exabisekileyo yokulawula umgangatho wamandla kunye nokuqinisekisa ukusebenza ngokufanelekileyo kothungelwano lokuhambisa.

Isishwankathelo, isethi epheleleyo yee-coil zokunciphisa i-arc enezigaba zibonelela ngesisombululo esinzima sokulawula ii-currents ezimfutshane kunye nokuphucula ukusebenza kwamanethiwekhi okusabalalisa.Imithetho-siseko yayo yesakhiwo kunye nokulawula iyenza ibe yinxalenye ebalulekileyo yeenkqubo zamandla zanamhlanje, igalelo ekuthembekeni okupheleleyo kunye nozinzo lweziseko zombane.
