Ua ntej, peb yam tseem ceeb ntawm AC contactor:
1. AC contactor coil.Ccoils feem ntau raug txheeb xyuas los ntawm A1 thiab A2, thiab tuaj yeem muab faib ua AC contactors thiab DC contactors.Peb feem ntau siv AC contactors, uas 220 / 380V yog qhov feem ntau siv:
2. AC Contactor Main tiv tauj.L1-L2-L3 yog txuas nrog peb-theem fais fab mov inlet kab, thiab T1 T2-T3 txuas nrog lub hwj chim qhov hluav taws xob kab, thiab siv tau los txuas rau cov kab load.Cov kev sib cuag tseem ceeb ntawm AC contactor feem ntau yog qhib kev sib cuag, feem ntau txuas nrog lub ntsiab Circuit Court, tswj kev pib thiab nres ntawm lub cev muaj zog thiab lwm yam khoom siv!
3. Pab tiv tauj ntawm AC contactor.Cov neeg pabcuam pabcuam tuaj yeem muab faib ua qhov qhib qhov chaw tsis tu ncua thiab ib txwm kaw qhov chaw NC.
3-1 Feem ntau qhib taw tes NO, feem ntau yog qhib taw tes NO yog tsuas yog siv rau contactor nws tus kheej-locking tswj thiab hloov chaw ua hauj lwm teeb liab siv, xws li: AC contactor feem ntau qhib taw tes NO mus rau ib tug liab qhia lub teeb yuav siv tau raws li lub cev muaj zog ua hauj lwm. qhov taw qhia lub teeb, thaum lub zog AC contactor, feem ntau qhib taw tes NO kaw, tig rau lub teeb qhia, xa lub cev muaj zog lossis lub teeb liab ua haujlwm.
3-2.Ib txwm-kaw point NC ntawm AC contactor.Feem ntau, NC feem ntau yog siv rau kev sib cuam tshuam hauv Circuit Court thiab teeb liab kis.
Piv txwv li, lub cev muaj zog zoo thiab rov qab tswj Circuit Court siv cov kev cuam tshuam kev ua haujlwm ntawm tus contactor tas li kaw point NC.
Piv txwv li, AC contactor tas li kaw point NC txuas nrog lub teeb pom kev ntsuab, uas tuaj yeem siv los ua qhov taw qhia nres ntawm lub voj voog lossis lub cev muaj zog.Thaum lub AC contactor yog powered up, qhov tas li kaw taw tes NC yog disconnected, lub nres qhov taw qhia lub teeb tawm, lub coj lub teeb qhia lub teeb nyob rau hauv, thiab lub Circuit Court khiav.
Qhov thib ob, kuv nkag siab peb yam ntxwv sab nraud ntawm AC contactor, thiab tom qab ntawd ua tib zoo saib sab hauv ntawm AC contactor:
Ua ntej, cov khoom tseem ceeb ntawm AC contactor: coil, hlau core, rov pib caij nplooj ntoos hlav, kev sib cuag system thiab armature thiab lwm yam khoom tsim.
1. Tsuas yog nkag siab txog qhov armature ntawm AC contactor.Lub armature txuas cov kev sib cuag, thaum lub armature txav nce thiab nqis, qhov chaw tiv tauj yuav hloov raws li, xws li: feem ntau qhib taw tes NO kaw, feem ntau kaw point NC disconnected thiab hais txog, qhov no yog qhov yooj yim siv!
2. Lwm yam khoom tseem ceeb: core, coils thiab pib dua springs!Kev nkag siab luv luv ntawm cov ntaub ntawv no yog:
Nov yog li cas AC contactors ua haujlwm hauv hom lus siv tau tshaj plaws:
Ua ntej AC contactor tsis siv hluav taws xob: lub kauj tsis tuaj yeem ua hluav taws xob, cov tub ntxhais tsis muaj hluav taws xob nqus, lub armature yuav tsis txav, lub caij nplooj ntoos hlav elasticity tseem zoo li qub, lub sij hawm no feem ntau qhib taw tes NO yog tawm, feem ntau kaw taw tes NC yog ntawm, qhov no yog lub xeev qub.
AC contactor hluav taws xob: coil hluav taws xob, hlau tub ntxhais tsim hluav taws xob nqus, tuaj yeem kov yeej lub caij nplooj ntoos hlav rov qab elasticity, rub lub ntsis txav, lub sijhawm no yuav hloov pauv: feem ntau qhib taw tes TSIS kaw, feem ntau kaw taw tes NC disconnected, qhov no yog qhov yooj yim tshaj plaws. contactor tswj, contactor yog los ntawm kev sib cuag on-off hloov mus indirectly tswj lub Circuit Court!
Tom qab AC contactor poob lub zog lossis lub zog tawm, lub kauj tsis tuaj yeem ua hluav taws xob, cov tub ntxhais tsis muaj hluav taws xob nqus, lub sij hawm no lub caij nplooj ntoos hlav elasticity rov pib dua, rov pib dua, armature bounce, lub sij hawm no lub armature tsav lub AC contactor hu rau lub zog txav, rov qab mus rau lub xeev pib: feem ntau qhib taw tes TSIS tau txiav, feem ntau kaw taw tes NC kaw rau.
