Dunhu guru rekutanga rakapfava rinoshandisa thyristor.Nekuchinja zvishoma nezvishoma kona yekuvhura ye thyristor, iyo voltage inosimudzwa kuti ipedze maitiro ekutanga.Uyu ndiwo musimboti wekutanga weiyo soft starter.Mumusika wepasi-voltage munyoro wekutanga, kune zvakawanda zvigadzirwa, asi iyomedium-voltage soft starterzvigadzirwa zvichiri zvishoma.
Nheyo yekutanga yepakati-voltage yakapfava yekutangisa yakafanana neyeyepasi-voltage yakapfava yekutangisa, asi pane inotevera misiyano pakati payo: (1) Medium-voltage soft starter inoshanda munzvimbo ine high-voltage, iyo insulation performance yakasiyana-siyana. zvikamu zvemagetsi zviri nani, uye simba rinopesana-kupindira remagetsi chip rakasimba.Apo iyomedium-voltage soft starterinoumbwa kuva kabati yemagetsi, kurongeka kwezvikamu zvemagetsi uye kubatanidzwa nepakati-voltage soft starter uye zvimwe zvigadzirwa zvemagetsi zvakakoshawo.(2) Iyo yepakati voltage soft starter ine yakakwira performance control musimboti, iyo inogona kugadzirisa chiratidzo panguva uye nekukurumidza.Naizvozvo, iyo yakakosha yekudzora inowanzo shandisa yakakwirira-inoshanda DSP chip, pane yakaderera-voltage yakapfava yekutanga yeMCU musimboti.Iyo huru yedunhu yeyakaderera voltage yakapfava starter inoumbwa neatatu inversely parallel thyristors.Zvisinei, mu-high-pressure soft starter, multiple high-voltage thyristors munhevedzano inoshandiswa pakuparadzana kwemagetsi nekuda kwekusakwana kwemagetsi ekupikisa kweimwe high-voltage thyristor.Asi maitiro ekuita ega ega thyristor haana kunyatsoenderana.Kusagadzikana kwe thyristor parameters kunotungamirira kune kusagadzikana kwe thyristor kuzarura nguva, izvo zvinotungamirira mukukuvadzwa kwe thyristor.Nokudaro, pakusarudzwa kwe thyristors, thyristor parameters yechikamu chimwe nechimwe inofanira kunge yakafanana sezvinobvira, uye zvikamu zvezvikamu zveRC filter circuit yechikamu chimwe nechimwe inofanira kunge yakafanana sezvinobvira.(3) Nzvimbo yekushanda yepakati-voltage yakapfava inotangisa inotarisana nekukanganiswa kwakasiyana kwemagetsi, saka kutapurirana kwechiratidzo chetrigger kwakachengeteka uye kwakavimbika.
Mune yepakati-voltage yakapfava yekutanga, iyo inokonzeresa siginecha inowanzo fambiswa neoptical fiber, iyo inogona kunyatso kudzivirira kwakasiyana kukanganiswa kwemagetsi.Pane nzira mbiri dzekutumira masaini kuburikidza neoptical fibers: imwe ine-multi-fiber, uye imwe yacho imwe-fiber.Mune akawanda-fiber modhi, imwe neimwe trigger board ine one optical fiber.Mune imwe-fiber mode, pane imwe chete fiber muchikamu chimwe nechimwe, uye chiratidzo chinotumirwa kune imwe huru trigger board, uye yozoendeswa kune mamwe matrigger board muchikamu chimwe chete neiyo main trigger board.Sezvo photoelectric transmission kurasikirwa kwega yega optical fiber isingaenderani, iyo imwe chete optical fiber inovimbika kupfuura yakawanda-optical fiber kubva pakuona kwe trigger consistency.(4) Medium-voltage soft starter ine zvakakwirira zvinodiwa pakuonekwa kwechiratidzo pane yakaderera-voltage soft starter.Kune kwakawanda kwekukanganisa kwemagetsi munzvimbo umo iyo yepakati-voltage yakapfava inotangisa iripo, uye vacuum yekubatanidza uye vacuum circuit breaker inoshandiswa munemedium-voltage soft starterichaburitsa yakawanda yekukanganisa kwemagetsi mukuita kwekupwanya nekuvhara.Naizvozvo, chiratidzo chakaonekwa hachifanirwe kungosefa nehardware, asiwo nesoftware kubvisa chiratidzo chekukanganisa.(5) Mushure mekunge iyo nyoro yekutanga yapedza maitiro ekutanga, inoda kushandura kune bypass inomhanya mamiriro.Maitiro ekushandura zvakanaka kune bypass inomhanya mamiriro zvakare kuomerwa kune yakapfava initiator.Nzira yekusarudza poindi yekunzvenga yakakosha.Iyo yekutanga bypass poindi, iko kuvhunduka kwazvino kwakasimba, kunyangwe pasi pemhepo yakadzika, inokonzeresa matatu-chikamu magetsi emagetsi wedunhu rwendo, kana kukuvadza wedunhu.Kukuvadza kwakakura pasi pemamiriro ekudzvinyirirwa.Iyo bypass point yanonoka, uye mota jitter zvakaipa, izvo zvinokanganisa kushanda kwakajairika kwemutoro.Naizvozvo, iyo bypass siginecha yekuona hardware yedunhu yakanyanya, uye chirongwa chekugadzirisa chinofanira kunge chakanyatso.
