Yuav ua li cas ntsuas kev ntsuas to furnage voltage thiab sib txawv ntawm cov xov tooj nyob thiab nruab nrab ntawm cov xov hlau
Yuav ua li cas ntsuas kev ntsuas to feakage nrog lub multimeter lossis hluav taws xob multimeter. Tam sim no, feem ntau ntawm cov hluav taws xob siv los ntawm cov lag luam thiab cov tsev neeg yog 220 volt ac Fais Fab. Txoj kab nruab nrab yog qhov av hauv av, thiab cov hlau tiv thaiv hauv av kuj tseem txuas nrog hauv av nyias. Yog li ntawd, qhov nruab nrab kab (ua haujlwm kab) thiab muaj cov hlau tiv thaiv hauv av tau tsim nyias, thiab tseem muaj qhov sib txawv ntawm ob hom hauv av. Yog li no, qhov sib txawv no tsuas tuaj yeem ze rau 36 volts. Yog tias qhov hluav taws xob tsawg dhau, nws yog qhov nyuaj kom paub qhov txawv ntawm kab ua haujlwm thiab cov hlau tiv thaiv hauv av, uas tau txiav txim siab yog tib tus hlau. Kev tiv thaiv lub ntiaj teb cov chaw tsis tuaj yeem muab kev tiv thaiv tsis txaus siab, uas yog qhov txaus ntshai heev.
Yog tias lub casing ntawm lub cuab yeej siv hluav taws xob siv hluav taws xob, nws yuav tsim kom muaj kev phom sij, uas tuaj yeem ua rau muaj kev txaus ntshai yog tias AC voltage ntau dua 36 volts.
Txhawm rau paub thiab ntsuas cov kev xau ntsuas qhov teeb meem, tus qauv yog yooj yim thiab siv tau, thiab cov qauv yog rudimentary. Tsuav muaj ntau npaum li ntawd muaj motionalimeter (ac iav lub taub hau los ntawm siab rau qis qis), ib sab tso rau ntawm seem ntub, thiab lwm txhais tes tau muab tso rau ntawm lub tshuab Casing. Yog tias lub voltage tshaj 36 volts, nws yog suav tias yog qhov kev nthuav dav txaus ntshai.
Ib qho ntxiv, nws yuav tsum tau sau tseg tias rau high-voltage ncaj qha hluav taws xob uas tsis ncaj qha rau hauv lwm qhov kawg, yuav tsis muaj voltage mus rau hauv av. Tab sis ceev faj tsis txhob kov ob kab hluav taws xob thib ob nrog ob txhais tes, uas tseem txaus ntshai heev.
Qhov yooj yim tshaj plaws yog kev ntsuas cov hlau nruab nrab, cov hlau nyob hauv av, thiab cov hlau sib txuas, teeb tsa cov digital puv rau AC hom, thiab teeb tus neeg kho tshuab multimeter rau ~. Qhov voltage theem yuav tsum siab dua cov ntsuas hluav taws xob, piv txwv li ntsuas 220 volts, muab tso rau 500 volts lossis 750 volts. Ib qho kawg yuav tsum tau cog rau hauv, xws li nyob rau hauv ib tug dej phwj lossis sab hauv qab xoom. Tsis yog ntawm cov chaw no tuaj yeem khi rau ntawm phab ntsa, tab sis nyob sab nraud ntawm cov nplais pob zeb sab. Nyob rau lub sijhawm no, cov voltage sib txawv vim tias cov dryness thiab ntub ntawm cov phab ntsa sib txawv, yog li cov voltage tseem yuav sib txawv. Tsuav nws nyeem ob peb kaum ntawm volts lossis ntau dua, cov xaim no yog cov hlau nyob. Disconnect lub Circuit Court breaker thiab siv ntau ntau ua ntsuas qhov tseem ceeb tshaj plaws. Tus taw tes hom yog 10K lossis 100k, thiab cov hom digital yog cov iav siab tshaj plaws. Cov hlau nrog kev nyeem tsawg tshaj plaws yog cov hlau av, thiab cov hlau nrog cov hlau loj dua yog qhov nruab nrab. Thaum lub sijhawm kev hloov dua siab tshiab ntawm tus phooj ywg lub tsev, lub zog siv hluav taws xob tom qab ua tiav. Cov neeg ua haujlwm txhim kho tshawb nrhiav rau lawv cov hluav taws xob rau ob hnub tab sis nrhiav tsis tau qhov txhaum. Lub tshuab hluav taws xob yuav tsum tau tig mus rau hluav taws xob hauv lub zos, uas tau ua haujlwm rau ob peb hnub tab sis nrhiav tsis tau muaj teeb meem. Tom qab ntawd, nws tau pom tias ob peb cov thom khwm tau sib xyaw nrog cov xov xwm tsis muaj zog thiab nyob hauv cov khoom sib xyaw, ua rau cov khoom siv hluav taws xob, uas tau ua rau cov khoom siv hluav taws xob thiab kev tawm mus.
Raws li rau kev siv hluav taws xob, yog tias nws yog cov khoom siv hauv tsev, siv ntau sib xyaw nrog 10k ntau yam los ntsuas qhov tau txais ib feem ntawm cov khoom siv. Yog tias cov kev tiv thaiv yog ntsuas kom muaj tsawg heev, ob peb ohms lossis ntau dua, cov rwb thaiv tsev lossis cov laus, thiab yuav muaj dej noo thiab noo noo. Cov khoom siv hauv tsev xws li cov khoos phis tawj, cov neeg hais lus, lwm yam yuav tsis tau sim vim tias qhov kev co meter voltage yog ntau cov hluav taws xob, uas tuaj yeem ua rau cov hluav taws xob sib xyaw. Yog tias muaj qhov xau xau nyob sab hauv tsev, koj tuaj yeem siv thawj zaug ntau ntawm kev ntsuas cov tawm tsam ntau. Kev paub qhia tias nws yuav luag tsis yooj yim sua kom ntsuas thaum nyob deb ntawm qhov chaw txhaum, uas yog, tus nqi tiv taus yog ntau thiab qee zaum nws tsis txav. Qhov ze dua rau qhov txhaum cai, tus me dua cov nqi tiv thaiv tsis kam. Qhov kev ua haujlwm no yog qhov ntau dua muaj txiaj ntsig dua li tuav lub ntsuas. Yog hais tias qhov dej xau yog qhov me me heev, lub rooj sib tuav yuav tsum tau siv rau kev ntsuas. Nyob rau hauv cov chaw nyob deb nroog, ib tus pas nrig hauv av yog ntxig thiab xaim txuas. Nyob rau sab nraud, txoj kev txiav tawm yog siv rau kev kuaj pom. Txij li thaum cov ris tsho nyob rau sab saud yog kev sib txuas nrog, kev sib tw tau swm los ntawm chav nruab nrab, ntsuas tau muab faib ua ob txoj hauv kev. Nov yog txoj kev kuaj pom yooj yim tshaj plaws.
