Contactor yog ib qho khoom siv hloov pauv tsis siv neeg siv los nquag hloov los yog tawm cov hluav taws xob tam sim no xws li AC thiab DC lub ntsiab circuits thiab cov khoom siv hluav taws xob loj.Nyob rau hauv cov nqe lus ntawm kev ua haujlwm, ntxiv rau kev hloov pauv tsis siv neeg, tus contactor kuj tseem muaj cov haujlwm ua haujlwm hauv chaw taws teeb thiab qhov poob ntawm qhov hluav taws xob (lossis undervoltage) kev tiv thaiv kev ua haujlwm uas phau ntawv hloov pauv tsis muaj, tab sis nws tsis muaj lub zog dhau thiab kev tiv thaiv luv luv ntawm lub zog. Tsawg-voltage Circuit Court breaker.
Qhov zoo thiab kev faib cov contactors
Lub contactor muaj qhov zoo ntawm kev ua haujlwm siab, lub neej ua haujlwm ntev, kev ua haujlwm ruaj khov, kev ua haujlwm ruaj khov, tus nqi qis, thiab kev saib xyuas yooj yim.Nws yog tsuas yog siv los tswj cov motors, hluav taws xob cua sov khoom, hluav taws xob vuam tshuab, capacitor banks, thiab lwm yam., thiab yog cov feem ntau siv nyob rau hauv hluav taws xob tsav tswj Circuit Court ib tug ntau yam ntawm kev tswj cov khoom.
Raws li daim ntawv ntawm lub ntsiab kev sib txuas Circuit Court, nws muab faib ua: DC contactor thiab AC contactor.
Raws li kev khiav hauj lwm mechanism, nws tau muab faib ua: electromagnetic contactor thiab mus tas li hlau nplaum contactor.
Cov qauv thiab kev ua haujlwm ntawm cov hluav taws xob qis AC contactor
Structure: AC contactor muaj xws li electromagnetic mechanism (coil, hlau core thiab armature), lub ntsiab kev sib cuag thiab arc extinguishing system, auxiliary contact thiab caij nplooj ntoos hlav.Cov kev sib cuag tseem ceeb tau muab faib ua choj hu xov tooj thiab cov ntiv tes sib cuag raws li lawv lub peev xwm.AC contactors nrog tam sim no ntawm ntau tshaj 20A yog nruab nrog arc extinguishing npog, thiab qee qhov kuj muaj cov phiajcim lossis sib nqus tshuab arc extinguishing;auxiliary contacts Cov ntsiab lus tau muab faib ua ib txwm qhib (tsiv los ze) kev sib cuag thiab ib txwm kaw (tsiv qhib) kev sib cuag, tag nrho cov uas yog choj-hom ob-tawg qauv.Kev sib tiv tauj muaj lub peev xwm me me thiab feem ntau yog siv rau kev sib cuam tshuam hauv kev tswj Circuit Court, thiab tsis muaj arc extinguishing ntaus ntawv, yog li nws tsis tuaj yeem siv los hloov lub ntsiab Circuit Court.Cov qauv yog qhia hauv daim duab hauv qab no:
Lub hauv paus ntsiab lus: Tom qab lub coil ntawm lub tshuab electromagnetic yog energized, magnetic flux yog generated nyob rau hauv lub hlau core, thiab electromagnetic attraction yog generated nyob rau hauv lub armature air gap, uas ua rau lub armature kaw.Lub ntsiab kev sib cuag tseem raug kaw nyob rau hauv lub tsav ntawm lub armature, yog li ntawd lub Circuit Court yog kev cob cog rua.Nyob rau tib lub sij hawm, lub armature tseem tsav cov neeg pab cuam los kaw cov kev sib txuas ib txwm qhib thiab qhib cov neeg uas ib txwm kaw.Thaum lub kauj yog de-energized los yog qhov voltage yog txo qis, lub zog nqus los yog tsis muaj zog, lub armature opens nyob rau hauv qhov kev txiav txim ntawm lub caij nplooj ntoos hlav tso tawm, thiab lub ntsiab thiab pab tiv tauj rov qab mus rau lawv cov qub lub xeev.Cov cim ntawm txhua feem ntawm AC contactor yog qhia hauv daim duab hauv qab no:
Cov qauv thiab cov cim qhia ntawm cov hluav taws xob qis AC contactors
1. Qauv ntawm low-voltage AC contactor
Feem ntau siv AC contactors tsim nyob rau hauv kuv lub teb chaws yog CJ0, CJ1, CJ10, CJ12, CJ20 thiab lwm yam ntawm cov khoom.Nyob rau hauv CJ10 thiab CJ12 series ntawm cov khoom, tag nrho cov cuam tshuam qhov chaw txais yuav ib tug buffer ntaus ntawv, uas yog tsim nyog yuav txo tau qhov kev sib cuag deb thiab mob stroke.Lub zog txav tau muaj qhov tsim nyog tsim nyog, cov qauv sib cog lus, thiab cov qauv kev sib txuas tsis muaj cov ntsia hlau, uas yooj yim rau kev txij nkawm.CJ30 tuaj yeem siv rau kev sib txuas ntawm cov chaw taws teeb thiab kev tawg ntawm circuits, thiab yog tsim rau nquag pib thiab tswj AC motors.
2. Kev ntsuas ntsuas ntawm cov hluav taws xob qis AC contactors
⑴ Rated voltage: yog hais txog qhov ntsuas hluav taws xob ntawm lub ntsiab tiv tauj.Cov qib siv feem ntau yog: 220V, 380V, thiab 500V.
⑵ Rated tam sim no: yog hais txog qhov ntsuas tam sim no ntawm lub ntsiab tiv tauj.Cov qib siv feem ntau yog: 5A, 10A, 20A, 40A, 60A, 100A, 150A, 250A, 400A, 600A.
⑶ Cov qib siv feem ntau ntawm cov ntsuas hluav taws xob ntawm lub kauj yog: 36V, 127V, 220V, 380V.
⑷ Rated ua hauj lwm zaus: yog hais txog tus naj npawb ntawm kev sib txuas hauv ib teev.
Kev xaiv lub hauv paus ntsiab lus ntawm low voltage AC contactor
1. Xaiv hom contactor raws li hom load tam sim no hauv Circuit Court;
2. Qhov ntsuas hluav taws xob ntawm lub contactor yuav tsum siab dua lossis sib npaug ntawm qhov ntsuas hluav taws xob ntawm lub voj voog load;
3. Qhov ntsuas qhov hluav taws xob ntawm cov coil attracting yuav tsum ua raws li qhov ntsuas hluav taws xob ntawm kev sib txuas tswj Circuit Court;
4. Qhov ntsuas tam sim no yuav tsum siab dua lossis sib npaug ntawm qhov ntsuas tam sim no ntawm cov tswj lub ntsiab.
