Taw qhia

Tus neeg tsav tsheb lub cev muaj zog yog qhov hloov pauv, vim tias lub cev muaj zog tsav tam sim no loj heev lossis qhov hluav taws xob siab heev, thiab cov kev hloov pauv dav dav lossis cov khoom siv hluav taws xob tsis tuaj yeem siv los ua kev hloov pauv los tswj lub cev muaj zog.

Lub luag haujlwm ntawm tus tsav lub cev muaj zog: Lub luag haujlwm ntawm tus tsav lub cev muaj zog yog hais txog txoj hauv kev kom ua tiav qhov kev tswj ntawm lub cev muaj zog tsis ua haujlwm los ntawm kev tswj lub kaum sab xis thiab kev khiav hauj lwm ceev ntawm lub cev muaj zog, thiaj li ua tiav kev tswj ntawm lub luag haujlwm lub voj voog.

Lub cev muaj zog tsav Circuit Court schematic daim duab: Lub cev muaj zog tsav Circuit Court tuaj yeem tsav los ntawm relay lossis fais fab transistor, lossis siv lub thyristor lossis lub zog MOS FET.Txhawm rau hloov kho kom haum rau kev tswj hwm sib txawv (xws li kev ua haujlwm tam sim no thiab qhov hluav taws xob ntawm lub cev muaj zog, kev tswj ceev ntawm lub cev muaj zog, kev tswj rau pem hauv ntej thiab thim rov qab ntawm DC lub cev muaj zog, thiab lwm yam), ntau hom kev tsav lub cev muaj zog yuav tsum tau ua raws li cov kev cai ntawm kev tswj hwm. muaj feem cuam tshuam.

Lub tsheb fais fab tsis pib thaum nws muaj zog, thiab nws ua haujlwm hnyav dua los thawb thiab nrog lub suab "choking".Qhov teeb meem no yog hais tias lub cev muaj zog cable yog luv luv vim yog kev sib cuag nrog lub virtual kev twb kev txuas, thiab qhov tshwm sim ntawm thawb lub laub nrog peb tuab theem kab ntawm lub cev muaj zog yuav unplugged thiab ploj, qhia tias tus maub los yog tawg thiab yuav tsum tau. hloov nyob rau hauv lub sij hawm.Yog tias nws tseem nyuaj rau kev siv, nws txhais tau hais tias muaj teeb meem nrog lub cev muaj zog, thiab nws yuav tshwm sim los ntawm qhov luv luv ntawm lub cev muaj zog coil raug hlawv.
