Daim ntawv thov Clamp Ammeter nyob rau hauv Kev Tshuaj Xyuas ntawm Cov Poob Platform Cheeb Tsam
Cov chaw nres tsheb loj heev feem ntau nrog cov teeb meem xws li hluav taws xob tub sab nyiag, xau, thiab ntsuas qhov tsis ua haujlwm. Nws tsis tsuas yog cuam tshuam rau cov txiaj ntsig kev lag luam ntawm cov khoom lag luam hluav taws xob, tab sis tseem cuam tshuam qhov kev txiav txim ntawm kev siv hluav taws xob. Nyob rau tib lub sijhawm, qhov teeb meem ntawm kev poob siab feem ntau tsis yog tshwm sim los ntawm ib qho teeb meem, tab sis kev sib xyaw ua ke ntawm ntau yam teeb meem, xws li 'meter' tsis ua haujlwm, hluav taws xob tub sab nyiag, lossis lwm yam teeb meem sib koom ua ke tib lub sijhawm. Yog li ntawd, nws yog ib qho nyuaj thiab nyuaj ua hauj lwm los kho qhov siab-poob platform cheeb tsam thiab txo cov kab poob ntawm high-loss platform cheeb tsam. Ntawm no peb tsuas yog tham txog qhov teeb meem leakage hauv siab poob. Muaj ntau yam teeb meem los ntawm kev poob siab, yuav ua li cas thiaj nrhiav tau lawv? Kev ua haujlwm tiag tiag ua pov thawj tias siv lub clamp ammeter los kuaj xyuas qhov xau sai thiab yooj yim.
Clamp ammeter: Ib qho ntsuas ntsuas uas tuaj yeem ntsuas qhov tam sim no hauv cov hlau los ntawm clamping lub puab tsaig ntawm cov hlau. Nws yog ib qho yooj yim mus use yam tsis muaj disconnecting cov hlau. Tam sim no, lub clamp ammeter tseem tuaj yeem paub txog kev ua haujlwm xws li ntsuas qhov ntsuas hluav taws xob thiab kev tiv thaiv los ntawm nws tus kheej ntsuas cwj mem.
High-loss platform thaj tsam: Cov kab poob tus nqi ntawm cov pej xeem transformer cheeb tsam yog tsawg dua 0, thiab nws yog ntau dua li cov theoretical kab poob, uas belongs rau qhov txawv txav platform poob. Ntawm lawv, kab poob tus nqi ntau dua li qhov theoretical kab poob belongs rau qhov poob siab platform. Raws li kev sib txawv hauv cheeb tsam, nws feem ntau tau teev tseg tias kab poob tus nqi ntau dua li ib qho nqi thiab yog nyob rau hauv qhov poob siab platform [1].
