Ntchito ya capacitor cabinet

Mfundo zoyambira zamakabati olipira ma capacitor okwera kwambiri: M'makina enieni amagetsi, katundu wambiri ndi ma asynchronous motors.Dera lawo lofanana limatha kuonedwa ngati gawo lotsatizana la kukana ndi inductance, ndi kusiyana kwakukulu pakati pa voteji ndi mphamvu yapano komanso yotsika mphamvu.Pamene ma capacitor akugwirizanitsidwa mofanana, mphamvu ya capacitor idzachotsa gawo lamagetsi opangidwa, potero kuchepetsa mphamvu yowonongeka, kuchepetsa chiwerengero chamakono, kuchepetsa kusiyana kwa gawo pakati pa magetsi ndi magetsi, ndikuwongolera mphamvu yamagetsi.1. Capacitor cabinet switching process.Pamene kabati ya capacitor yatsekedwa, gawo loyamba liyenera kutsekedwa poyamba, ndiyeno gawo lachiwiri;potseka, zosiyana ndi zoona.Kusinthana kwa makabati ogwiritsira ntchito capacitor.Kutseka pamanja: Tsekani chosinthira chodzipatula → sinthani chosinthira chowongolera chachiwiri kupita kumalo amanja ndikutseka gulu lililonse la ma capacitor amodzi ndi amodzi.Kutsegula pamanja: sinthani chosinthira chowongolera chachiwiri kupita kumalo amanja, tsegulani gulu lililonse la ma capacitor amodzi ndi amodzi → kuswa chosinthira chodzipatula.Kutseka kokha: Tsekani chosinthira chodzipatula → sinthani chosinthira chowongolera chachiwiri kuti chikhale chodziwikiratu, ndipo chowongolera mphamvu chimangotseka capacitor.Zindikirani: Ngati mukufuna kutuluka mu nduna ya capacitor panthawi yogwira ntchito, mutha kukanikiza batani lokhazikitsiranso pa chowongolera mphamvu kapena kutembenuza chosinthira chachiwiri kukhala zero kuti mutuluke pa capacitor.Osagwiritsa ntchito chosinthira chodzipatula kuti mutuluke molunjika pa capacitor!Pamene kusintha kwamanja kapena kwadzidzidzi, chidwi chiyenera kulipidwa pakusintha mobwerezabwereza kwa banki ya capacitor mu nthawi yochepa.Nthawi yochedwa yosinthira siyenera kukhala yochepera masekondi a 30, makamaka kuposa masekondi a 60, kuti alole nthawi yokwanira yotulutsa ma capacitor.2. Imani ndikupereka mphamvu ku nduna ya capacitor.Asanapereke mphamvu ku nduna ya capacitor, wophwanya dera ayenera kukhala pamalo otseguka, chosinthira cholamula pagawo la opareshoni chiyenera kukhala pagawo la "Stop", ndipo chowongolera chowongolera mphamvu chiyenera kukhala pa "OFF".Pokhapokha makinawo atayimitsidwa kwathunthu ndikuyendetsa bwino mphamvu zitha kuperekedwa ku nduna ya capacitor.Kugwiritsa ntchito pamanja kabati ya capacitor: kutseka chowotcha cha capacitor capacitor, sinthani chosinthira chowongolera pagawo la opareshoni kupita ku malo 1 ndi 2, ndikulumikiza pamanja chipukuta misozi 1 ndi 2;tembenuzirani chosinthira cholamula kukhala "mayeso", ndipo nduna ya capacitor idzayesedwa mabanki a Capacitor.Kugwira ntchito kwa capacitor capacitor: kutseka chowotcha cha capacitor capacitor, sinthani cholumikizira cholumikizira pagawo la opareshoni kupita pagawo la "automatic", kutseka chowongolera chowongolera mphamvu (ON), ndikusintha kusintha kwa lamulo ku "run". ” udindo.” udindo.Kabati ya capacitor imangolipira mphamvu yamagetsi yamagetsi malinga ndi makonda adongosolo.Malipiro a pamanja angagwiritsidwe ntchito pokhapokha kubweza kwa capacitor capacitor kulephera.Pamene kusintha kwa lamulo pa gulu la opareshoni la capacitor capacitor kusinthidwa kukhala "kuyimitsa", nduna ya capacitor imasiya kuthamanga.atatu.Zowonjezerapo za makabati a capacitor.Chifukwa chiyani nduna yamalipiro ya capacitor ilibe chosinthira mpweya koma imadalira fuse kuti itetezere dera lalifupi?Ma fuse amagwiritsidwa ntchito makamaka poteteza dera lalifupi, ndipo ma fuse othamanga ayenera kusankhidwa.Miniature circuit breakers (MCBs) ali ndi mawonekedwe osiyana ndi ma fuse.Kuthyoka kwa MCB ndikotsika kwambiri (<=6000A).Ngozi ikachitika, nthawi yoyankhira ya kabowo kakang'ono sikothamanga ngati fusesi.Mukakumana ndi ma harmonics apamwamba kwambiri, chowotcha chaching'ono sichingathe kusokoneza katundu wamakono, zomwe zingapangitse kuti kusinthaku kuphulika ndikuwonongeka.Chifukwa cholakwacho ndi chachikulu kwambiri, zolumikizirana ndi chowotcha chaching'ono zitha kutenthedwa, zomwe zimapangitsa kuti zikhale zosatheka kuthyoka, kukulitsa kukula kwa vutolo.Zikavuta kwambiri, zimatha kuyambitsa kuzungulira kwachidule kapena kuzimitsa kwamagetsi muzomera zonse.Chifukwa chake, MCB singagwiritsidwe ntchito ngati m'malo mwa fuse mu makabati a capacitor.Momwe fusesi imagwirira ntchito: Fuseyi imalumikizidwa motsatizana ndi dera lotetezedwa.Muzochitika zabwinobwino, fusesi imalola kuchuluka kwa mphamvu yamagetsi kudutsa.Pamene dera liri lalifupi kapena lolemedwa kwambiri, mphamvu yaikulu yowonongeka imadutsa mu fusesi.Pamene kutentha kopangidwa ndi panopa kufika pa malo osungunuka a fuse, fuseyi imasungunuka ndikudula dera, potero kukwaniritsa cholinga cha chitetezo.Chitetezo cha ma capacitor ambiri chimagwiritsa ntchito ma fuse kuteteza ma capacitor, ndipo zowononga madera sizigwiritsidwa ntchito kawirikawiri, pafupifupi palibe.Kusankhidwa kwa ma fuse kuti muteteze ma capacitor: Mawonekedwe amakono a fusesi sayenera kuchepera 1.43 nthawi yamagetsi ya capacitor, ndipo sayenera kukhala wamkulu kuposa 1.55 nthawi yamagetsi ya capacitor.Yang'anani kuti muwone ngati wowononga dera lanu ndi wocheperapo.Capacitor idzapanga mafunde enaake akamalumikizidwa kapena kulumikizidwa, kotero chophwanya dera ndi fusesi ziyenera kusankhidwa kuti zikhale zazikulu pang'ono.
