Imbaraga za Electronics Ibikoresho byo Gushyushya Induction

Gushyushya induction bikoreshwa cyane cyane mu gushonga ibyuma, kubika ubushyuhe, gucumura, gusudira, kuzimya, ubushyuhe, diathermy, kweza ibyuma byamazi, gutunganya ubushyuhe, kunama imiyoboro, no gukura kwa kirisiti.Amashanyarazi ya induction agizwe numuzunguruko ukosora, umuzenguruko wa inverter, imizigo yimizigo, kugenzura no kurinda umutekano.

Ikoreshwa rya tekinoroji yo gukwirakwiza amashanyarazi yo gushyushya induction ni tekinoroji ikosora uburyo bwo guhinduranya amashanyarazi agezweho (50Hz) kugirango yerekane ingufu hanyuma ihindurwe mumashanyarazi yo hagati (400Hz ~ 200kHz) binyuze mumashanyarazi ya semiconductor nka thyristor, MOSFET cyangwa IGBT.Ikoranabuhanga riranga muburyo bworoshye bwo kugenzura, imbaraga nini zisohoka, hamwe nubushobozi buhanitse kurenza igice, kandi byoroshye guhindura inshuro ukurikije ubushyuhe busabwa.

Ikosora ryibikoresho bito n'ibiciriritse bitanga amashanyarazi bifata ibyiciro bitatu byo gukosora thyristor.Kubikoresho bitanga amashanyarazi menshi, hazakoreshwa 12-pulse ya thyristor ikosora kugirango urwego rwamashanyarazi rutangwe kandi bigabanye imiyoboro ihuza imiyoboro.Inverter power unit igizwe na voltage nini-nini-yihuta yihuta ya thyristor parallel hanyuma urukurikirane ruhujwe no kumenya ingufu nyinshi zisohoka.

Inverter na resonant umuzenguruko urashobora kugabanwa muburyo bubiri ukurikije imiterere yuburyo: 1) ubwoko bwa parallel resonant, 2) ubwoko bwa resonant ubwoko.

Ubwoko bubangikanye na rezont: umuyaga mwinshi-mwinshi-ukonjesha amazi-thyristor (SCR) ukoreshwa mugukora amashanyarazi agezweho-inverter power power, kandi ingufu nyinshi ziva mubikorwa na superistosition ya thyristors.Umuzunguruko wa resonant muri rusange ukoresha imiterere ya parallel yuzuye ya resonance, uhitemo kandi na voltage ebyiri cyangwa transformateur kugirango wongere imbaraga kuri inductor ukurikije ibisabwa bitandukanye, bikoreshwa cyane muburyo bwo kuvura ubushyuhe.

Ubwoko bwa resonant ubwoko: voltage-nini-y-amazi-akonje ya thyristor (SCR) hamwe na diode yihuta bikoreshwa mugukora amashanyarazi ya voltage yo mu bwoko bwa inverter power, kandi ingufu nyinshi zigerwaho no kurengerwa na thyristors.Inzira ya resonance ikoresha urukurikirane rw'imiterere, kandi transformateur yemewe kugirango ihuze umutwaro usabwa.Usibye ibyiza byingufu zingirakamaro kuri Grid-kuruhande, uburyo bwagutse bwo guhindura ingufu, ubushyuhe bwinshi hamwe nigipimo kinini cyo gutangiza, cyarushijeho gukoreshwa cyane mumyaka yubu kandi gikoreshwa cyane mugushonga.

Nyuma yo kunoza imikorere yinganda, Runau yakoze byihuse yihuta ya thyristor ikoresha imirasire ya neutron nibindi bikorwa kugirango irusheho kugabanya igihe cyo kuzimya kandi imbaraga zongerewe imbaraga.

Induction yo gushyushya imashini itanga amashanyarazi ikoresha thyristor nkigikoresho nyamukuru cyamashanyarazi cyatwikiriye imirima yose hamwe na frequency ikora munsi ya 8kHz.Ubushobozi bwo gusohora ingufu bugabanijwemo 50, 160, 250, 500, 1000, 2000, 2500, 3000kW, 5000KW, 10000KW inshuro zikoreshwa ni 200Hz, 400Hz, 1kHz, 2.5kHz, 4kHz, 8kHz.Toni 10, toni 12, toni 20 zo gushonga ibyuma no kubika amashyuza, ibikoresho nyamukuru byamashanyarazi ni amashanyarazi yo hagati.Noneho ingufu ntarengwa zisohoka ziza kuri 20000KW ya 40Ton.Kandi thyristor nurufunguzo rwimbaraga zihindura & inversion zigomba gukoreshwa.
