Main Classifications ntawm Contactors

Raws li lawv cov kev npaj siv thiab kev tsim qauv, contactors tuaj yeem muab faib ua ob hom loj: AC contactors thiab DC contactors. AC contactors feem ntau yog ua haujlwm hauv AC circuits; Cov yam ntxwv ntawm lawv cov qauv yooj yim, muaj peev xwm tawg siab, thiab kev ua haujlwm ruaj khov, lawv tau siv dav hauv kev tswj lub cev muaj zog, hluav taws xob tsav, thiab cov cuab yeej siv tshuab. DC contactors, conversely, feem ntau yog siv nyob rau hauv DC circuits thiab yuav tsum superior arc -extinguishing peev xwm; lawv feem ntau pom nyob rau hauv cov sectors xws li lub zog tshiab, hluav taws xob tsheb, thiab tsheb ciav hlau thauj mus los.

Tsis tas li ntawd, raws li lawv cov qauv kev khiav hauj lwm thiab cov yam ntxwv ntawm kev ua haujlwm, cov contactors tuaj yeem muab faib ua hom xws li electromagnetic contactors, lub tshuab nqus tsev contactors, thiab solid-state contactors. Electromagnetic contactors cia siab rau electromagnetic attraction los actuate qhib thiab kaw ntawm kev sib cuag thiab tam sim no sawv cev rau feem ntau siv hom. Lub tshuab nqus tsev contactors siv lub tshuab nqus tsev ib puag ncig los tua cov arcs, muab qhov zoo xws li lub neej ua haujlwm ntev thiab kev saib xyuas tsawg kawg nkaus. Khoom-lub xeev contactors, ntawm qhov tod tes, ntiav cov khoom siv hluav taws xob rau kev tswj hwm thiab tsis muaj kev sib cuag; yog li ntawd, lawv muab kev hloov ceev ceev thiab suab nrov qis, ua rau lawv haum rau siab - zaus hloov daim ntawv thov.

Contactors tseem tuaj yeem raug cais raws li lawv txoj kev txuas thiab kev ua haujlwm ib puag ncig-piv txwv li, ruaj khov -hom contactors, reversible contactors, lossis tawg-cov ntaub ntawv pov thawj. Tsau - hom contactors muaj kev ruaj khov thiab tsim nyog rau cov khoom siv dav dav. Reversible contactors pab tswj kev sib hloov ntawm lub cev muaj zog hauv ob qho tib si rau pem hauv ntej thiab rov qab cov lus qhia thiab tau siv dav hauv cov tshuab xa hluav taws xob. Explosion-cov ntaub ntawv pov thawj yog tsim los siv rau hauv qhov chaw tawg los yog tawg, qhov chaw uas lawv ua haujlwm tau zoo los tiv thaiv cov khoom siv thiab cov neeg ua haujlwm. Txhua yam sib txawv ntawm cov contactors ua lub luag haujlwm tseem ceeb hauv kev lag luam automation thiab lub zog tswj cov tshuab.
