1. Txoj hauj lwm pab tiv thaiv tsis tsim nyog.
Tom qab qhov hloov pauv poob rau ntau zaus, cov khoom siv kho tshuab muaj qhov txav thiab hnav tshwm sim, ua rau muaj qhov sib txawv ntawm qhov chaw sib tiv tauj mus rau txoj haujlwm raug. Nyob rau hauv kev tiv thaiv kev mus ncig, thaum lub koom haum pab tsis tau txiav tawm, cov khoom siv hluav taws xob xa tawm, cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob tau rov qab los, uas yog, cov khoom siv hluav taws xob nruab nrab thiab kev sib txuas lus sib txuas tau raug txiav ua ntej kev sib cuag.
Qhov no ua rau cov khoom siv nruab nrab, cov kev sib txuas lus sib txuas kom tsis txhob cuam tshuam DC fais fab mov thiab hlawv. Yog li ntawd, nyob rau hauv kev huam yuaj, txawm tias qhov kev tiv thaiv tau tsiv mus, tab sis qhov hloov pauv tsis txav, ua rau muaj kev mus los ntawm leapfrog.
2, qhov hloov pauv mus txawv tebchaws mechanism daim npav lub zog.
Hloov tshuab vim tsis muaj kev saib xyuas, kev ua haujlwm tsis zoo, muaj qhov chaw muaj zog, tsis tuaj yeem mus txawv tebchaws, ua rau cov khoom siv nruab nrab, relay coil tau ntev, ua rau cov khoom nruab nrab, relay coil hlawv, tsis tuaj yeem. ua kom raug.
3, hloov coil core tawm los yog daig.
Vim qhov kev ua haujlwm ib txwm muaj ntawm qhov hloov pauv thiab qhov tsis ua haujlwm, cov hlau sab saum toj yog xoob, ua rau lub hauv paus hloov mus poob. Thaum qhov tsis ua haujlwm tshwm sim, qhov hloov pauv tsis tuaj yeem poob, ua rau lub qhov hluav taws xob nruab nrab ntawm cov khoom siv hluav taws xob thiab relay tau them rau lub sijhawm ntev, thiab hlawv cov khoom siv hluav taws xob, relay coil lossis kev sib cuag.
Cov ntaub ntawv txuas ntxiv
Relays feem ntau muaj induction mechanism (input part) uas tuaj yeem cuam tshuam qee qhov kev hloov pauv (xws li tam sim no, voltage, kub, siab, ceev, lub teeb, thiab lwm yam); thiab muaj actuator (tso tawm ib feem) uas tuaj yeem paub "ntawm" thiab "so" tswj ntawm cov tswj Circuit Court.
Kuj tseem muaj cov txheej txheem nruab nrab (tsav ib feem) rau kev sib txuas ntawm cov khoom siv thiab kev sib cais ntawm cov khoom nkag thiab cov khoom tso tawm ntawm cov relay, kev ua haujlwm thiab tsav cov khoom tso tawm.
Raws li kev tswj hwm, hauv cov ntsiab lus, lub relay muaj cov haujlwm hauv qab no:
1) Nthuav cov tswj ntau yam: piv txwv li, thaum lub teeb liab tswj ntawm ntau qhov sib tiv tauj relay nce mus txog ib qho nqi, nws tuaj yeem hloov pauv, qhib thiab txuas ntau lub voj voog raws li ntau hom kev sib cuag ntawm pawg.
2) amplification: piv txwv li, rhiab relay, intermediate relay, thiab lwm yam, nrog ib tug heev me me tswj tus nqi, yuav tswj tau ib tug siab zog Circuit Court.
3) Cov teeb liab dav dav: Piv txwv li, thaum lub plurality ntawm cov teeb liab tswj tau nkag mus rau hauv ntau qhov cua relay nyob rau hauv daim ntawv sau npe, qhov kev txiav txim siab tswj tau ua tiav los ntawm kev sib txuas ntau dua.
4) Tsis siv neeg, chaw taws teeb tswj, saib xyuas: piv txwv li, lub relay ntawm lub tshuab tsis siv neeg, ua ke nrog lwm cov khoom siv hluav taws xob, tuaj yeem tsim cov kab kev tswj hwm, kom paub txog kev ua haujlwm tsis siv neeg.
