Kev xaiv lub sij hawm relay feem ntau yog ib qho teeb meem ntawm kev ncua sijhawm thiab kev sib koom ua ke. Cov nram qab no yuav tsum tau txiav txim siab thaum xaiv.
(1) Xaiv qhov ncua sij hawm. Muaj ob hom relays lub sij hawm: lub hwj chim-on ncua los yog lub hwj chim-off ncua, uas yuav tsum tau xaiv raws li qhov yuav tsum tau ntawm kev tswj Circuit Court. Lub sijhawm rov pib dua tom qab ua haujlwm ntev dua li lub sijhawm ua haujlwm hauv lub cev kom tsis txhob ua haujlwm tsis zoo lossis txawm tias tsis ncua sijhawm. Qhov no yog ib qho tseem ceeb tshwj xeeb tshaj yog nyob rau hauv kev rov ncua circuits thiab nquag ua haujlwm.
(2) Hom kev xaiv. Rau lub sijhawm uas qhov kev ncua sijhawm tsis yog siab, cov nqi qis dua electromagnetic lossis cua damping lub sij hawm relays feem ntau yog siv; conversely, rau lub sij hawm uas ncua qhov tseeb yog siab, hluav taws xob lub sij hawm relays yuav siv tau.
(3) Coil voltage xaiv. Qhov voltage ntawm lub sij hawm relay attraction coil yog xaiv raws li kev tswj Circuit Court voltage.
(4) Kev xaiv cov khoom siv hluav taws xob hloov pauv. Nyob rau hauv cov xwm txheej uas lub hwj chim mov voltage fluctuates zoo heev, nws yog zoo dua los siv cua-damped los yog hluav taws xob lub sij hawm relays dua transistor hom. Txawm li cas los xij, nyob rau hauv cov xwm txheej uas cov khoom siv hluav taws xob hloov pauv tau zoo heev, nws tsis tsim nyog siv hluav taws xob lub sij hawm relays. Nyob rau hauv qhov chaw uas qhov kub hloov pauv zoo heev, nws tsis tsim nyog siv cov cua-damped lub sij hawm relays. Damped lub sij hawm relay.
