Chekutanga, iyo yekutanga performance research yemidziyo yemagetsi
nyika yangu yakatanga kushandisa vacuum chubhu mukutanga 1980s.Parizvino, ma switch evacuum emugodhi anoputika ave kushandiswa zvakanyanya mumigodhi yepasi.Kushandiswa kwevacuum chubhu kwaita basa guru mukuchengetedza magetsi mumigodhi yemarasha.Semuyenzaniso, kuputika-proof vacuum electromagnetic starter zvigadzirwa zvemigodhi zvine simba rekupedzisira rekupwanya, iyo inokodzera kugara uchitanga mota dzepasi pevhu uye yakaderera kugadzirisa;mine kuputika-uchapupu zvigadzirwa Nguva yakazara yekupwanya yerudzi rwevacuum feed switch idiki, uye pamwe nekudzivirira kwekukurumidza kuvuza, inovandudza kuchengetedzwa kwe-anti-shock uye anti-gasi kuputika.Iko kudiwa kwevacuum contactors uye vacuum circuit breakers yakakura kwazvo, asi mhando yevacuum chubhu mumusika wazvino hauna kuenzana.Mazhinji maitiro ekugadzira achiri akavakirwa pamavambo ma1980 uye achiri akakura zvichienzaniswa nemaitiro ekunze.gap.Mukushandiswa kwevacuum tubes, kunewo simba rekushanda overvoltage uye vimbiso yevacuum.Kudzikira kwevacuum kunogona kukonzera tsaona yekudonha mutsime, zvichikanganisa kugadzirwa uye tsaona.Mamwe makambani atangawo kuzvipira kutsvagurudzo yevacuum chubhu yemagetsi midziyo yemagetsi, uye Tsvagiridzo yekudzivirira kubuda kwemhepo yakafambira mberi mukudzivirira kubuda kwemhepo uye vacuum chubhu adhesion kuchengetedza nzira.Iri ndiro remangwana
Ipa vimbiso yekushanda kwakachengeteka kwemidziyo yemagetsi yepasi pevhu.Nekuenderera mberi kwekuvandudza tekinoroji yemagetsi, kushandiswa kwemagetsi emagetsi kutsiva vacuum machubhu kuona kutanga uye kumisa kutonga kwemota kuchave nzira yekusimudzira.Yakashandiswa mukutonga kwekuchengetedzwa kwakazara kwemarasha emagetsi emagetsi, akadai seasina kuonana kuvhara kwe thyristors.Kudzora, kuwedzera hupenyu hwesevhisi, yakachengeteka uye yakavimbika.Iko kushandiswa kwepamusoro-simba SCR mukutanga kwakashandurawo mashandiro echinyakare kutanga.Nepo kushandiswa kwemagetsi emagetsi kunopa hutsva hutsva mukuita uye kuvimbika kwekuputika-kusaputsika zvigadzirwa zvemagetsi, zvinounza zvakare nyaya nyowani kune inoputika-uchapupu uye kuchengetedza tekinoroji zvinodiwa zvezvigadzirwa.
Chechipiri, iyo yakasarudzika leakage tsvakiridzo yeyakaderera-voltage feed switch
Dziviriro yekuvuza ndechimwe chezvitatu zvakakura dziviriro yemidziyo yemagetsi yepasi pevhu mumigodhi yemarasha, uye kuvimbika kwekuchengetedzwa kwayo kunokanganisa kugadzirwa kwekuchengetedza mugodhi wemarasha.Iyo yazvino yakasarudzika yekudzivirira yekudzivirira misimboti yeyakaderera-voltage feeder switch ichiri yakavakirwa pakudzivirira modhi ye zero-kutevedzana voltage uye zero-kutevedzana ikozvino;uyezve, yekunze DC inoshandiswa kuramba ichitarisisa kuvharwa kweiyo magetsi ekupa network.Nekuda kwekurebesa kwesimba rekupa magetsi uye kushandiswa kwetambo dzakavharidzirwa, pamwe nekushandiswa kwemagetsi emagetsi emagetsi senge ma frequency converter, network yepasi pevhu yemagetsi yakaoma.Kune akawanda akarasika maitiro mukusarudza leakage dziviriro uye kusavimbika kwekugovaniswa capacitance.Zvinodiwa zvekudzivirira kudonha zvinoiswa pamberi.Uchishandisa tekinoroji yepamusoro yekutora dhijitari, maitiro ekuongorora mamiriro eiyo yakagovaniswa capacitance mutsime, kuwana chaiyo yakasarudzika yekutsika uye kucheka bazi rine mhosva pasina kukanganisa mamwe matavi anoshanda, uye kuve nechokwadi kuti yakavimbika uye yakachengeteka magetsi epasi pevhu zvakare itsva. musoro unoda kukurumidza kudzidzwa.
Chechitatu, kuvandudzwa kwemigodhi AC inverter zvigadzirwa
Nekuda kwekuenderera mberi nekufambira mberi kwesainzi uye tekinoroji, kushandiswa kwemidziyo yemagetsi ine simba guru mumigodhi yepasi pevhu kwakakura nekukurumidza.Pakati pavo, iyo AC inosiyana frequency yekumhanyisa regulation mudziyo ine zvakanakira kushanda kwakanyanya, yakaderera kutadza mwero, uye yakanaka kudzora kuita, iyo inogona zvakanyanya kuvandudza maitiro ekugadzira.Nekutarisisa kweindasitiri yekugadzira marasha, mugodhi wefrequency conversion control control mudziyo unoshandiswa kunyanya kushandiswa kudzora kumhanya kweanenge 100kW, senge marasha emigodhi emagetsi emagetsi ekudhonza zvikamu.Kazhinji, nhanho yepamberi ine shanduko yakakosha yekupa simba, iyo ine zvishoma zvinokanganisa pane gidhi remagetsi.Nekudaro, sezvo tekinoroji inoshandura tekinoroji ichiramba ichikura, kubva pakabudirira kushandiswa kwevageri vemagetsi muma1980s, midziyo yekugadzira migodhi yemarasha yakaita semamhepo, mawinji, hoist, air compressors uye zvimwe zvemichina zvemuchina zvatanga kushandisa frequency yekushandura kukurumidza kudzora tekinoroji. .Haisi kungoshandura maitiro echinyakare ekugadzira, asi zvakare anonyanya kuverengerwa mukuita kwakanyanya uye kuchengetedza simba.Semuenzaniso, fan huru yemugodhi inosarudzwa zvichienderana nehupamhi hwemhepo inodiwa yehupenyu hwebasa rekugadzira mugodhi.Kubva pakuvakwa kweshaft kusvika pakugadzirwa kusvikira mugodhi wabviswa, huwandu hwemhepo hunodiwa munguva imwe neimwe yakasiyana, uye kusiyana kwakakura zvikuru.Kushandiswa kwekugadzirisa kwemagetsi kwehuwandu hwemhepo kunokonzera kukanganisa kwakawanda kwemagetsi.Mafeni anochengetedza simba nekushandisa frequency converter tekinoroji.Mumwe muenzaniso ndewekuti mafeni emunharaunda mumigodhi yechiso akaiswa munzvimbo dzakawanda uye anomhanya kwenguva yakareba, inova mutengi mukuru wesimba.Nekuda kwekuenderera mberi kwekuwedzera kwekucherwa kwemarasha, huwandu hwemhepo hunodiwa kwenguva yakareba hwakanyanya kuderera kupfuura hwemhepo.Kuwanda kwemhepo yemuchina, tichitarisa mamiriro azvino erudzi urwu rwetrolley huru inodhonzwa nebhiza, simba rekuchengetedza simba rekushandisa frequency conversion speed regulation tekinoroji iri pachena zvakare.Nekuda kwekushanda kwakanyanya kweiyo frequency converter uye yakanaka yekumhanyisa regulation kuita, inogona kushandisa magetsi braking uye isina nhanho yekumhanya mutemo kuchengetedza simba.Itsika isingadzivisiki kushandisa tekinoroji yekushandura frequency zvakanyanya mumigodhi yemarasha.Asi parizvino, hapana kuvandudza chigadzirwa kana tekinoroji yekuyedza inogona kuenderana nezvinodiwa zvekugadzirwa kwekugadzira.
Zvinoenderana neruzivo rwechishandiso chepasi frequency shanduko yekumhanyisa kudzora mudziyo, zvinodikanwa kushandisa zvakanaka frequency yekushandura kukurumidza kudzora mudziyo, uye magetsi emagetsi, frequency inoshandura mota, uye michina yekugadzira inofanirwa kusanganiswa nehunyanzvi hwekugadzira. system yekudzidza, uye matanho akakodzera ekudzvinyirira achatorwa kune harmonics yemagetsi grid.Kuti uenderane nekuvandudza tekinoroji yemagetsi emugodhi wemarasha, tsvagurudza mashandiro emagetsi emagetsi epamusoro-soro ekushandura migodhi, tsvakiridzo yeFrequency converter EMC nemhedzisiro yemafungu ekudzvinyirira nhanho uye dzimwe nyaya dzehunyanzvi, uye kupa yepamberi. tekinoroji yemunda wekutsvagisa kwesainzi, dhizaini uye kugadzirwa kwemugodhi frequency converters.Chikuva chekuyedza chave pedyo.
Maitiro ekuita ekuona EMC kuitira kuti mine frequency converter ishandiswe mumugodhi wemarasha "girinhi" uye kuderedza kukuvadzwa kwekugadzirwa kwemigodhi yemarasha yave musoro wakakosha wedhipatimendi rekuona muchikamu chinotevera.
nyika yangu ndiyo inogadzira marasha makuru pasi rose, uye marasha ndiwo ane simba guru renyika yangu.Tichitarisa budiriro yemapoinzi matatu ari pamusoro, kuvandudzwa kwemichina yekucherwa kwemarasha nekuisa magetsi kuburikidza nekuvandudzwa kweruzivo rwemichina kwakakosha zvikuru mukuvandudzwa kwemigodhi yemarasha.Kuti isangane nezvinodiwa zvebhizinesi tekinoroji kuvandudza uye kusimudzira, sangano redu rekuyedza rinoenderera mberi nekuvandudza kugona kwaro uye nekupa nzira dzepamberi dzekuyedza uye nzira dzekuyedza.Mukupindura kune zvinodiwa zvekuvandudza tekinoroji, iyo National Safety Production Shanghai Mining Equipment Inspection Center yakaramba ichivandudza kugona kwayo kwekuongorora uye mazinga.Semuenzaniso, tangi yakakura yekuputika-proof test tank ye 3.4m yakabatanidzwa muprojekti yakarongwa kuti ienderane nekuongororwa kwezvigadzirwa zvemagetsi zvemigodhi mikuru.Kudiwa: Iko kugona kwekutarisa kwemugodhi-kuputika-proof inverters kuchasimudzwa kusvika padanho re1000kW kusangana nezvinodiwa zvekuyedzwa zvemahombe-akakwira-voltage motors uye akakwira-voltage inverters.Dhipatimendi redu rekuyedza richashandisa tekinoroji yekuyedza tekinoroji senzira yekusimbisa kuchinjana nekushandira pamwe nemabhizinesi, uye nekupa rutsigiro rwehunyanzvi hwehunyanzvi hwekuvandudza uye kuchengetedza manejimendi ezvigadzirwa zvemagetsi zvinoputika.
