Hloov mus tswj cov hluav taws xob xaim nrog tus cwj mem los ntsuas xoom xaim me ntsis ntawm lub teeb, nws zoo li cas?
Ua ntej tshaj plaws, nws yuav tsum paub meej tias, txawm hais tias qhov hluav taws xob xaim (lub sij hawm thev naus laus zis rau theem kab) tsis tau raug txiav tawm, txoj kab xoom hauv qhov xwm txheej tsis raug them. Yog tias txoj kab xoom muaj zog, kab qhov chaw muaj teeb meem, ces yuav ua li cas thiaj paub qhov teeb meem nyob qhov twg? Rau cov neeg siv hluav taws xob dav dav, sib qhia ib txoj hauv kev yooj yim thiab siv tau sai sai nrhiav thiab daws nrog:
Ua ntej, rau cov lus piav qhia txog qhov teeb meem no, vim tias txoj kab xoom yog me ntsis ci, qhov ua rau ntawm qhov tshwm sim no, feem ntau yog xoom kab lap ntawm qhov tshwm sim oxidation, uas ua rau kev sib cuag tsis zoo, tab sis qhov xwm txheej no tuaj yeem txiav txim siab yog lub ntsiab kab xoom kab. tawg teeb meem, vim hais tias lub ntsiab kab xoom kab tawg lossis kev sib cuag tsis zoo, uas ua rau qhov tshwm sim tsis ua haujlwm thiab qhov tshwm sim ntawm qhov sib txawv, ntawm no yuav tsis raug tshuaj xyuas.
Thib ob, segmented kev tshawb nrhiav, nqaim lub peev xwm, ua ntej kos tus tswv hloov hauv qhov chaw kaw, qhov hloov pauv nce thiab nqis ntawm pawg lub taub hau xoom kab yog qhov qub, yog tias xoom kab yog ib txwm tsis muaj hluav taws xob, feem ntau yog qhov hloov pauv tom qab seem ntawm cov qhov teeb meem, koj tuaj yeem tshawb xyuas cov pob qij txha ntawm kab los ntawm ntu kom pom qhov yuam kev tom qab rewiring thiab wrapping tuaj yeem ua tau. Vim tias qhov teeb meem feem ntau yog nyob rau hauv txoj kab kev sib txuas. Qhov xwm txheej no tshwm sim feem ntau, feem ntau ntev dhau los, cov kab hluav taws xob qub, tam sim no cov kab hluav taws xob sab hauv tsev thiab kev teeb tsa yog kev tshawb fawb heev, feem ntau yuav tsis tshwm sim qhov teeb meem no.
Thib peb, yog tias koj xyuas qhov hloov pauv nce thiab nqis ntawm pawg, tsis muaj lub zog ntawm pawg lub taub hau xoom kab, nyob rau hauv pawg lub taub hau lub zog, qhov no feem ntau yog qhov hloov pauv tsis zoo, koj tuaj yeem qhib thiab kaw qhov hloov pauv ob peb zaug, thiab qee zaum tuaj yeem kho lub zog ib ntus, tab sis tseem yuav tsum tau hloov pauv raws sijhawm.
Xyuas yog tias qhov hloov ntawm pawg lub taub hau xoom kab kuj raug them, qhov xwm txheej no feem ntau tuaj yeem hu rau kev kho xov tooj xwb, vim tias tej zaum yuav muaj kev tshuaj ntsuam xyuas, tus neeg siv tsis tuaj yeem daws tau yooj yim.
Muaj ob txoj hauv kev, ua ntej, qee qhov hloov pauv ntawm phab ntsa txhawm rau tso cai rau cov neeg siv kom pom qhov hloov pauv hauv qhov tsaus ntuj tuaj yeem ua tau zoo, nyob rau hauv kev hloov ntawm lub teeb, thaum lub teeb tawm, lub teeb no tseem muaj me me tam sim no los ntawm lub teeb. hloov. Qhov thib ob, tag nrho cov teeb fluorescent, txawm tias cov raj fluorescent zoo tib yam lossis lub teeb txuag hluav taws xob, cov phosphor muaj qee lub sij hawm ncua kev ploj tuag, hu ua "afterglow". Niaj hnub no, nrog rau kev nce qib ntawm kev tshawb fawb, cov kua siv lead ua kua thiab cov khoom siv sib xyaw ua ke, nws yog ib qho yooj yim los tso saib tej yam uas tsis tshwm sim tib lub sijhawm hauv tib lub vijtsam. Piv txwv li, lub ntsuas hluav taws xob electrocardiogram (ECG) qhia txog kab uas hloov pauv mus thiab nqis raws li lub plawv dhia, tab sis qhov tseeb txhua qhov kev hloov pauv ntawm kab no tsis yog tib yam tshwm sim tib lub sijhawm, tab sis kuj muaj qhov sib txawv. txheej txheem ntawm lub sijhawm. Yav dhau los, tsuas yog CRT saib lub sijhawm, tsuas yog ib qho taw tes nrog lub plawv dhia thiab hloov pauv, txhawm rau ua kom pom ib kab, koj yuav tsum siv lub ntsuas "ntev tom qab", kom qhov ntsuas qhov taw qhia tom qab dhau los tsis yog tam sim ntawd tua. , tab sis tom qab ib lub sij hawm ntev ntawm lub sij hawm thiab ces maj mam extinguished, kom lub zog ntawm ib tug taw tes mus rau hauv ib tug kab ntawm cov zaub. Tseem muaj oscilloscopes thaum lub sij hawm ntawm tib txoj cai.
Zero Zero kab yog lub voj voog ntawm txhua yam khoom siv hluav taws xob, vim tias muaj qee qhov kev tiv thaiv ntawm xoom kab, qhov ntau dua qhov kev tiv thaiv ntawm xoom kab lossis ntau dua qhov tam sim no ntawm xoom kab, qhov siab dua qhov sib thooj voltage saum toj no. Yog li cov kab xoom tsis yog tag nrho tsis muaj hluav taws xob, lub stylus yog me ntsis ci kuj ua tau. Tau kawg, yog tias xoom kab hluav taws xob muaj kev sib cuag tsis zoo, thiab lwm yam, yuav ua rau xoom kab hluav taws xob siab. Yog li nws yog qhov zoo tshaj plaws los siv lub voltmeter los ntsuas qhov voltage.
Transformer tawm ntawm ib theem ntawm lub fuse yuav kuj ua rau xoom kab nrog ib tug hluav taws xob cwj mem los ntsuas lub teeb, thaum muaj ib tug lub cev muaj zog hlawv tawm nyob rau hauv txoj kab nyob deb tawm muaj ib theem ntawm lub cev muaj zog grounded yuav kuj ua rau hluav taws xob cwj mem. ntsuas qhov zero kab teeb. Zero line disconnected fais fab mov los ntawm cov khoom siv kuj yuav ntsuas qhov xoom kab nrog hluav taws xob cwj mem yog ci dua.
Nws yog qhov yooj yim heev, tsuav yog qhov xoom Circuit Court yog qhov zoo conduction, nws tsis tuaj yeem tshwm sim qhov tshwm sim no. Qhov tshwm sim no paub tseeb tias qhov xoom kab hluav taws xob qhov chaw muaj qhov tawg lossis tsis zoo conduction lossis strung rau hauv cov khoom siv. Txoj kev daws teeb meem yog txiav tawm qhov xoom Circuit Court lossis qhov tsis zoo ntawm qhov kev sib txuas, yog tias ib lub voj voog rau hauv ob lub cuab yeej, txiav tawm ib qho khoom siv, tsuas yog ib qho khoom siv tau khaws cia.
