AC zolumikiziraamagawidwa mu AC contactors (ntchito voteji AC) ndi DC contactors (voltage DC), amene amagwiritsidwa ntchito uinjiniya mphamvu, zipangizo kugawa mphamvu ndi malo engineering mphamvu.AC contactor theoretically amatanthauza chipangizo chapakhomo chomwe chimagwiritsa ntchito koyilo kupanga gawo lamagetsi amagetsi malinga ndi kuchuluka kwa mafakitale omwe amapanga kuti azimitse cholumikizira cha AC kuti chiwongolere katundu.
AC contactor ndi mphamvu lophimba ndi ulamuliro dera ambiri ntchito monga kotunga magetsi.Imagwiritsa ntchito gawo lalikulu lolumikizirana kuti muyatse ndikuzimitsa dera lamagetsi, ndipo imagwiritsa ntchito malo olumikizirana othandizira kuti akwaniritse zowongolera pulogalamu.Malo olumikizana nawo nthawi zambiri amakhala ndi malo olumikizirana otsegula ndi otseka, ndipo malo olumikizirana othandizira nthawi zambiri amakhala ndi magawo awiri olumikizana ndi ntchito zotsegula ndi kutseka komanso zotseka nthawi zambiri.Zolumikizira zazing'ono za AC nthawi zambiri zimagwiritsidwa ntchito ngati ma relay ang'onoang'ono komanso mabwalo akuluakulu amagetsi.The kukhudzana pamwamba pa AC contactor amapangidwa ndi aloyi silver-tungsten, amene ali madutsidwe wabwino magetsi ndi kukana matenthedwe mng'alu.
A DC contactor ndi AC contactor ntchito dera DC.Imafanana ndi AC contactor ndipo kawirikawiri ali chachikulu kukhudzana pamwamba.Thandizani ndi malo olumikizirana komanso malo olumikizirana ma coil.Tengani DC contactor akuwonetsedwa mu chithunzi monga chitsanzo.Imatengera ma modularization ndipo imatha kusonkhanitsa machitidwe okhudza kukhudza ndi njira zomwe makasitomala amafunikira (nthawi zambiri amayatsidwa, nthawi zambiri amazimitsa ndikusintha);mndandanda mankhwala ali mkulu kukhudza mphamvu lophimba ntchito voteji ndi mlingo kuwomba electromagnetic munda arc kuzimitsa, pazipita mphamvu lophimba ntchito voteji chingapezeke 220VDC.Izi ndizoyenera kuwongolera makina osinthira magetsi kapena pulogalamu yamagetsi yamagetsi, forklift yamagetsi, pulogalamu yamagetsi yamakina amagetsi amagetsi atsopano.
Mapangidwe ndi mfundo za olumikizirana ndi DC ndizofanana ndi zolumikizira ma AC, ndipo amapangidwanso ndi bungwe la electromagnetic induction, pulogalamu ya touch system ndi zida zozimitsira ma arc, koma bungwe la electromagnetic induction ndi losiyana.
Nthawi zambiri, kusiyana kwa kapangidwe ka DC contactor ndi AC contactor zimadalira: chitsulo pachimake koyilo si zophweka chifukwa Eddy ndi Eddy panopa imfa kuwonongeka malinga ndi magetsi DC, choncho n'kosavuta kutentha.Pofuna kuwongolera bwino kupanga ndi kukonza, chitsulo chachitsulo chimapangidwa ndi zitsulo zonse zofatsa.Pofuna kupangitsa kuti kutentha kwa koyilo kukhale bwino, koyiloyo nthawi zambiri imadulidwa kukhala mawonekedwe owonda kwambiri, omwe amalumikizana mwachindunji ndi chitsulo, chomwe chimakhala chosavuta kutentha kutentha.Tiyeni tione kusiyana zinayi pakati pa DC contactors ndi AC contactors.
Kusiyana kwakukulu ndi AC contactor ndi DC contactor.
1. Chitsulo chachitsulo ndi chosiyana: chitsulo chachitsulo cha AC contactor chidzachititsa kuwonongeka kwa eddy ndi eddy panopa, pamene contactor ya DC ilibe kuwonongeka kwachitsulo.Choncho, pachimake chitsulo cha AC contactor wapangidwa ndi silicon mbale zitsulo ndi zigawo ziwiri zoteteza, kawirikawiri E-zoboola pakati;pachimake chitsulo cholumikizira cha DC chimapangidwa ndi zitsulo zonse zofatsa, zambiri zomwe zimakhala zooneka ngati U.
2. Mapulogalamu a pulogalamu yozimitsa ya arc ndi yosiyana: zida zozimitsa za grid arc zimasankhidwa kwa AC contactor, ndipo chipangizo chozimitsa maginito cha arc chimasankhidwa kwa DC contactor.
3. Chiwerengero cha kutembenuka kwa koyilo ndi kosiyana: kuchuluka kwa koyilo yokhotakhota ya AC contactor ndi yaying'ono, kuchuluka kwa kutembenuka kwa koyilo ya DC contactor kumakhala kofala kwambiri mumagetsi a DC, AC contactor imagawidwa mudera la AC, ndipo cholumikizira cha DC chimagawidwa m'dera la DC.
4. Nthawi yeniyeni yogwiritsira ntchito ndi yosiyana: AC contactor ili ndi ntchito yaikulu yamakono, yochuluka ndi nthawi 600 / ola, ndipo ntchitoyo ndi yotsika mtengo.The DC contactor akhoza kufika 2000 nthawi/ola, ndi mtengo ntchito ndi mkulu.
Kodi ma AC olumikizirana ndi ma DC angasinthidwe?
1. AC contactor ingagwiritsidwe ntchito kwa DC contactor mwadzidzidzi, ndipo kukoka-mu nthawi sangakhoze kupitirira 2 hours (chifukwa kutentha kutentha kwa AC koyilo ndi koipa kuposa DC, amene ali mu mawonekedwe ake osiyana) .Ndi bwino kulumikiza kukana mu mndandanda ndi koyilo AC, koma DC sangathe m'malo AC contactor;
2. Chiwerengero cha kutembenukira kwa AC contactor koyilo ndi yaing'ono, ndipo chiwerengero cha mokhota wa DC contactor koyilo ndi lalikulu.Pamene panopa wa dera lalikulu mphamvu ndi lalikulu kwambiri (IE250A), ndi AC contactor ntchito mndandanda-olumikizidwa pawiri-zokhota koyilo;
3. The DC relay coil resistor ndi yaikulu ndipo panopa ndi yaying'ono.Ngati sichikuwonongeka mosavuta polumikizana ndi magetsi a AC, chonde chiyikeni pomwepo.Komabe, coil ya AC galimoto yolumikizira ili ndi chopinga chaching'ono komanso kuchuluka kwapano.Ngati ilumikizidwa ndi magetsi oyendetsedwa ndi DC, koyiloyo idzawonongedwa;
4. Chiwerengero cha kutembenukira kwa AC contactor koyilo ndi yaing'ono ndi resistor ndi yaing'ono.Koyiloyo ikalowa munjira yosinthira, padzakhala kukana kwakukulu kwa maginito, komwe kumaposa kukana kwa koyiloyo.Chinsinsi cha mphamvu yachisangalalo cha koyilo ndi kukula kwa kukana kwa maginito kugunda kwamphamvu.Ngati magetsi a DC alowa mkati, koyiloyo ingakhale katundu wodziletsa.Panthawiyi, kuchuluka kwa zomwe zikudutsa pa koyiloyo zidzakhala zazikulu kwambiri, zomwe zimapangitsa kuti koyiloyo ikhale yotentha kapena kuwotcha.Choncho, AC contactors sangathe ntchito monga DC contactors.
