1) Dab tsi yog qhov sib txawv ntawm DC thiab AC contactors ntxiv rau lub kauj?
2) Dab tsi yog qhov teeb meem yog tias AC lub zog thiab qhov hluav taws xob txuas lub kauj ntawm lub ntsuas hluav taws xob ntawm lub kauj thaum qhov voltage thiab tam sim no zoo sib xws?
Teb rau nqe lus nug 1:
Lub kauj ntawm DC contactor yog qhov siab thiab nyias, thaum lub AC contactor coil yog luv thiab rog. Yog li ntawd, lub coil tsis kam ntawm DC coil yog loj, thiab coil kuj ntawm AC coil yog me me.
DC contactors thiab DC relays feem ntau siv ob lub kauj, qhov tam sim no coil yog siv rau kev nqus thiab cov kauj hluav taws xob yog siv los nqus tuav.
AC contactor yog ib lub kauj.
Cov tub ntxhais hlau thiab armature ntawm DC contactor yog tag nrho cov hluav taws xob muag hlau, thiab AC contactor yog silicon steel ntawv pawg txhawm rau txo qhov poob ntawm AC.
Lub flux nyob rau hauv AC contactor core yog alternating thiab muaj tshaj xoom.Lub sij hawm no, lub armature yuav thaws rov qab nyob rau hauv cov tshuaj tiv thaiv quab yuam, thiab ces tuav tom qab xoom, yog li ntawd lub AC contactor core yuav tsum tau nruab nrog ib tug luv luv Circuit Court voj kom tshem tawm. magnetic los ntawm xoom oscillation.
contactors thiab relay coils tsim overvoltage thaum tso tawm, DC contactors thiab relays feem ntau tshem tawm nrog rov qab diodes, thiab AC contactors thiab relays nrog RC circuits.
DC contactor tiv tauj arc nyuaj, kom phim sib nqus tshuab arc.AC contactor yog qhov yooj yim rau arc, siv C-zoo li tus qauv thiab lub rooj vag arc.
Teb rau lo lus nug 2:
Lub DC contactor coil tam sim no me me thaum lub DC voltage yog AC zoo voltage. Yog li ntawd, thaum ob lub hwj huam mov hloov, lub DC contactor yuav tsis koom, thiab AC contactor hlawv tam sim ntawd.
Tsis tas li ntawd, DC contactor tam sim ntawd kub hnyiab tom qab qhov kev txhawb nqa txuas ntxiv ntawm AC Circuit Court.
