AC contactorsmuab faib ua AC contactors (ua hauj lwm voltage AC) thiab DC contactors (voltage DC), uas yog siv nyob rau hauv hluav taws xob engineering, hluav taws xob faib khoom thiab hluav taws xob engineering chaw.AC contactor theoretically yog hais txog cov khoom siv hauv tsev uas siv lub kauj los tsim cov khoom siv hluav taws xob raws li cov khoom lag luam tam sim no los tua AC contactor los tswj cov khoom thauj.
AC contactor yog lub hwj chim hloov thiab tswj Circuit Court feem ntau siv los ua lub zog hloov hluav taws xob.Nws siv lub ntsiab tiv tauj saum npoo los qhib thiab tawm lub zog hluav taws xob, thiab siv qhov chaw sib tiv tauj los siv kev tswj hwm.Qhov chaw sib cuag tseem ceeb feem ntau tsuas yog qhib thiab kaw qhov chaw sib cuag, thiab qhov chaw sib tiv tauj feem ntau muaj ob khub ntawm qhov chaw sib cuag nrog lub luag haujlwm ntawm kev qhib thiab kaw thiab ib txwm kaw.Me AC contactors feem ntau yog siv los ua cov relays me me thiab lub zog hluav taws xob loj.Kev sib cuag ntawm AC contactor yog ua los ntawm cov nyiaj-tungsten alloy, uas muaj cov hluav taws xob zoo thiab thermal tawg tsis kam.
DC contactor yog AC contactor siv nyob rau hauv DC Circuit Court.Nws phim AC contactor thiab feem ntau muaj qhov sib tiv tauj loj.Pab nrog cov chaw sib cuag thiab cov ntsiab lus coil.Coj tus DC contactor qhia hauv daim duab ua piv txwv.Nws txais yuav modularization thiab tuaj yeem sib sau ua ke cov txheej txheem kov thiab kov txoj kev xav tau los ntawm cov neeg siv khoom (feem ntau tig, feem ntau tua thiab hloov);Cov khoom no muaj lub siab kov lub zog hloov kev khiav hauj lwm voltage thiab theem tshuab electromagnetic teb arc extinguishing, lub siab tshaj plaws fais fab hloov kev khiav hauj lwm voltage yuav ua tau tiav 220VDC.Cov khoom no yog tsim rau kev tswj kev hloov hluav taws xob hloov hluav taws xob lossis ups fais fab system software, hluav taws xob forklift, lub zog tshiab hluav taws xob tsheb siv tshuab khoom siv software.
Cov yam ntxwv thiab cov ntsiab lus ntawm DC contactors yog ib qho zoo ib yam li cov AC contactors, thiab lawv kuj yog tsim los ntawm electromagnetic induction lub koom haum, kov system software thiab arc extinguishing khoom, tab sis lub koom haum electromagnetic induction yog txawv.
Feem ntau hais lus, qhov sib txawv ntawm cov qauv ntawm DC contactor thiab AC contactor nyob ntawm: cov tub ntxhais hlau coil tsis yooj yim ua rau eddy thiab eddy tam sim no poob kev puas tsuaj raws li DC fais fab mov, yog li nws tsis yooj yim rau kub.Txhawm rau txhim kho kev tsim khoom thiab ua kom zoo dua qub, cov tub ntxhais hlau yog ua los ntawm cov hlau me me.Txhawm rau ua kom cov coil cua sov dissipation zoo tshaj plaws, lub kauj yog feem ntau raug mob rau hauv cov duab cylindrical nyias, uas ncaj qha hu rau cov tub ntxhais hlau, uas yooj yim heev rau cua sov dissipation.Cia peb saib plaub qhov sib txawv ntawm DC contactors thiab AC contactors.
Qhov sib txawv tseem ceeb yog AC contactor thiab DC contactor.
1. Cov tub ntxhais hlau yog txawv: cov tub ntxhais hlau ntawm AC contactor yuav ua rau eddy thiab eddy tam sim no poob kev puas tsuaj, thaum lub DC contactor tsis muaj hlau core puas.Yog li ntawd, cov tub ntxhais hlau ntawm AC contactor yog tsim los ntawm silicon steel daim hlau nrog cov txheej txheem insulating, feem ntau E-puab;Cov tub ntxhais hlau ntawm DC contactor yog ua los ntawm cov hlau me me, feem ntau yog U-shaped.
2. Lub software ntawm lub arc extinguishing system yog txawv: daim phiaj arc extinguishing khoom raug xaiv rau AC contactor, thiab lub magnetic blowing arc extinguishing device yog xaiv rau DC contactor.
3. Tus naj npawb ntawm cov kauj hloov yog txawv: tus naj npawb ntawm cov kauj hloov ntawm AC contactor yog me me, tus lej hloov ntawm DC contactor coil yog ntau dua nyob rau hauv DC fais fab mov, AC contactor muab faib ua AC Circuit Court, thiab DC contactor muab faib ua DC Circuit Court.
4. Qhov tseeb kev khiav hauj lwm zaus yog txawv: AC contactor muaj kev khiav hauj lwm loj tam sim no, qhov siab tshaj plaws yog 600 zaug / teev, thiab daim ntawv thov yog tus nqi qis.DC contactor tuaj yeem ncav cuag 2000 zaug / teev, thiab daim ntawv thov raug nqi siab.
AC contactors thiab DC contactors puas tuaj yeem hloov pauv?
1. Lub AC contactor tuaj yeem siv rau DC contactor thaum muaj xwm txheej ceev, thiab lub sijhawm rub tawm tsis tuaj yeem tshaj 2 teev (vim tias cov cua kub dissipation ntawm AC coil yog qhov phem dua li ntawm DC, uas nyob hauv nws cov qauv sib txawv) .Nws yog qhov zoo tshaj plaws los txuas cov kev tiv thaiv hauv koob nrog AC coil, tab sis DC tsis tuaj yeem hloov AC contactor;
2. Tus naj npawb ntawm cov lem ntawm AC contactor coil yog me me, thiab tus naj npawb ntawm cov lem ntawm DC contactor coil yog loj.Thaum lub tam sim no ntawm lub ntsiab fais fab Circuit Court loj dhau (IE250A), AC contactor siv ib tug series-txuas ob-winding coil;
3. DC relay coil resistor yog loj thiab tam sim no me me.Yog tias nws tsis yooj yim puas los ntawm kev txuas mus rau AC fais fab, thov tso nws tam sim ntawd.Txawm li cas los xij, AC tsheb relay coil muaj qhov me me resistor thiab muaj qhov loj ntawm tam sim no.Yog tias nws txuas nrog DC tswj fais fab mov, lub kauj yuav raug rhuav tshem;
4. Tus naj npawb ntawm cov lem ntawm AC contactor coil yog me me thiab cov resistor me me.Thaum lub kauj nkag mus rau qhov hloov pauv tam sim no, yuav muaj qhov sib nqus sib nqus loj induction kev sib txhuam, uas deb tshaj qhov tsis kam ntawm lub kauj.Tus yuam sij rau lub zog excitation ntawm lub kauj yog qhov loj ntawm qhov sib nqus induction kev sib txhuam.Yog hais tias lub DC tam sim no yuav tsum ntws mus rau hauv, lub kauj yuav dhau los ua ib qho kev tiv thaiv tsis muaj zog.Lub sijhawm no, tus nqi tam sim no dhau los ntawm lub kauj yuav loj heev, ua rau lub kauj kub kub lossis txawm tias hlawv.Yog li, AC contactors tsis tuaj yeem siv ua DC contactors.
