Yuav kom daws tau qhov teeb meem hluav taws xob zoo, koj yuav tsum paub tias txhua qhov hluav taws xob hauv chav tsev yuav tsum ua haujlwm li cas thiab tuaj yeem ntsuas qhov ua tau zoo ntawm txhua qhov khoom. Cov ntaub ntawv hluav taws xob, cov ntawv luam tawm, schematics, thiab cov ntaub ntawv tsim khoom-ua ke nrog koj qhov kev paub thiab kev paub dhau los-yuav pab koj txiav txim siab seb txhua yam yuav tsum ua haujlwm li cas. Tom qab txiav txim siab cov yam ntxwv ntawm kev ua haujlwm, siv cov ntsuas hluav taws xob kom tau txais cov yam ntxwv ua haujlwm tam sim no ntawm lub voj voog.

Qee qhov xwm txheej kuj xav tau kev sim rau lub zog, lub zog muaj zog, zaus, theem kev sib hloov, inductance, capacitance, thiab impedance. Ua ntej pib qhov kev xeem, teb tsib nqe lus nug nram qab no:

● Puas yog lub voj voog qhib lossis kaw?

● Cov fuses lossis breakers yog dab tsi?

● Cov txiaj ntsig ntawm kev tshuaj xyuas qhov muag yog dab tsi?

● Puas muaj kev txiav txim tsis zoo?

● Puas yog lub ntsuas ntsuas ua haujlwm?

Cov ntsuas ntsuas thiab cov cuab yeej ntsuas, nrog rau cov cuab yeej luam tawm, xws li kev khiav hauj lwm cav thiab schematics, yuav pab koj kuaj xyuas thiab daws teeb meem hluav taws xob. Cov cuab yeej siv tshuaj ntsuam xyuas thiab cov cuab yeej ntsuas yog voltmeter, ammeter, thiab ohmmeter. Cov haujlwm tseem ceeb ntawm cov ntsuas no tau muab tso rau hauv ib lub multimeter.

Voltmeters

Siv lub voltmeter los ntsuas qhov muaj peev xwm ntawm lub cev muaj zog. Nrog lub tshuab hluav taws xob khiav, qhov hloov tau kaw, thiab cov voltmeter probes txuas nrog tam sim no tus neeg xyuas pib thiab nruab nrab tus neeg xyuas pib sib txuas ntawm lub cev muaj zog, voltmeter yuav qhia qhov muaj peev xwm ntawm lub cev muaj zog. Qhov ntsuas voltmeter tsuas pom muaj qhov muaj hluav taws xob. Nws yuav tsis qhia tias lub cev muaj zog tig los yog qhov tam sim no ntws.

Ammeters

Lub clamp-on ammeter yog siv los ntsuas qhov amperage hauv lub cev muaj zog. Nrog lub tshuab hluav taws xob khiav, qhov hloov tau kaw, thiab lub puab tsaig ammeter clamped nyob ib ncig ntawm cov hlau lead, lub ammeter yuav qhia qhov amperage kos, los yog tam sim no, siv los ntawm Circuit Court. Txhawm rau kom tau txais kev nyeem ntawv tseeb thaum siv lub clamp-on ammeter, clamp lub meter lub puab tsaig nyob ib ncig ntawm ib lub xaim, lossis txhuas, ib zaug, thiab xyuas kom lub puab tsaig kaw tag.

Ohmmeters

Lub ohmmeter ntsuas qhov tsis kam ntawm lub cev muaj zog. Ua ntej pib qhov kev ntsuas ohmmeter, qhib qhov hloov pauv uas tswj lub cev muaj zog, txuas cov khoom tsim nyog kaw / tagout, thiab cais lub cev muaj zog ntawm lub voj voog. Kev ntsuas ohmmeter tuaj yeem txheeb xyuas qhov luv lossis qhib Circuit Court.

Quick-Test Instruments

Ntau qhov tshwj xeeb, siv tau, thiab pheej yig cov cuab yeej hluav taws xob muaj rau siv hauv kev daws teeb meem hluav taws xob. Ua ntej siv cov cuab yeej ntsuas hluav taws xob, nco ntsoov tias lawv ua raws li OSHA cov cai tam sim no.

Cov ntsuas hluav taws xob yog cov cuab yeej zoo li cwj mem siv los kuaj xyuas qhov muaj AC voltage tshaj 50 volts. Cov ntsuas hluav taws xob muaj txiaj ntsig zoo thaum kuaj xyuas qhov tawg hauv AC xaim. Thaum lub hau yas ntawm qhov taw qhia tau siv rau txhua qhov kev sib txuas los yog ib sab ntawm ib lub xaim nrog AC voltage, lub hau yuav ci los yog lub cuab yeej yuav tawm suab nrov. Cov ntsuas hluav taws xob tsis ntsuas qhov hluav taws xob AC ncaj qha; lawv qhia txog qhov muaj peev xwm voltage.

Circuit analyzers ntsaws rau hauv tus qauv receptacles thiab tuaj yeem ua haujlwm raws li qhov ntsuas hluav taws xob yooj yim, qhia qhov muaj hluav taws xob muaj. Cov khoom siv plug-in no feem ntau siv los ntsuas qhov tsis muaj hauv av, rov qab polarity lossis nruab nrab, thiab qhov poob qis. Lawv kuj tau siv los xyuas GFCI. Sophisticated versions ntawm cov cuab yeej no tuaj yeem tshawb xyuas qhov hluav taws xob surges, qhov tsis tseeb, lub peev xwm tam sim no, impedance, thiab kev nyab xeeb kev nyab xeeb.

Infrared scanners yog siv tsis tu ncua los xyuas seb puas muaj teeb meem hluav taws xob. Raws li amperage dhau los ntawm ib qho khoom siv hluav taws xob, cua sov yog tsim nyob rau hauv kev faib ua feem rau qhov kev tiv thaiv tsim. Ib qho infrared scanner qhia txog qhov kub thiab txias sib txawv ntawm cov khoom thiab tuaj yeem ua haujlwm los qhia qhov kub thiab txias. Yog tias ib qho hluav taws xob lossis cov khoom kub kub dua li cov khoom nyob ib puag ncig nws tam sim ntawd, cov cuab yeej ntawd lossis kev sib txuas yuav tshwm sim raws li qhov kub ntawm lub scanner. Txhua qhov kub kub yog cov neeg sib tw rau kev tshuaj xyuas ntxiv lossis kev daws teeb meem. Cov teeb meem kub-spot feem ntau tuaj yeem daws tau los ntawm kev kho lub torque ntawm cov neeg xav tias kev sib txuas hluav taws xob mus rau theem tsim nyog lossis los ntawm kev ntxuav thiab zawm txhua qhov txuas. Cov txheej txheem no kuj tseem tuaj yeem kho cov theem tsis sib xws.

Cov kab hluav taws xob

Ib lub voj voog taug qab yog ib qho khoom siv uas, thaum txuas mus rau ib qho chaw nkag tau hauv lub voj voog, tuaj yeem taug qab txoj kab hluav taws xob los ntawm lub tsev - txhua txoj hauv kev mus rau qhov kev pabcuam nkag, yog tias tsim nyog. Circuit Court tracers muaj ob ntu:

●Teeb liab generator:Txuas mus rau lub xov tooj hluav taws xob thiab tsim cov xov tooj cua-yoj-hom teeb liab thoob plaws hauv lub voj voog.

●Lub teeb liab receiver:Nrhiav cov kab hluav taws xob los ntawm kev txais xov tooj cua teeb liab los ntawm kev xaim.

Hluav taws xob cov ntaub ntawv, luam tawm, Schematics, thiab Manufacturers cov ntaub ntawv

Raws li muaj txiaj ntsig zoo li qee yam ntawm cov cuab yeej no, cov ntaub ntawv feem ntau sib npaug lossis tseem ceeb dua. Cov ntaub ntawv soj ntsuam thiab cov cav khiav haujlwm muaj xws li cov ntaub ntawv xws li amperage draws thiab kev khiav hauj lwm kub thiab siab ntawm cov khoom. Ib qho kev hloov pauv ntawm ib qho ntawm cov kev ntsuas no tuaj yeem qhia qhov teeb meem muaj peev xwm. Thaum muaj qhov teeb meem pom tseeb, cov ntaub ntawv tshuaj xyuas thiab cov ntaub ntawv ua haujlwm tuaj yeem pab koj sib piv cov haujlwm tam sim no ntawm cov cuab yeej siv rau kev ua haujlwm ib txwm muaj. Qhov kev sib piv no tuaj yeem pab koj txheeb xyuas cov teeb meem tshwj xeeb.

Piv txwv li, qhov nce hauv kev khiav hauj lwm amperage kos ntawm lub cev muaj zog tsav lub twj tso kua mis qhia tias muaj teeb meem tshwm sim. Kev ceeb toom txog kev hloov pauv ntawm qhov qub amperage kos, koj tuaj yeem ua qhov kev ntsuam xyuas ntxiv, xws li kuaj xyuas qhov ntsuas kub ntawm cov bearings. Tsis tas li ntawd, yog tias qhov kub thiab txias ntawm cov bearings yog siab tshaj qhov kev khiav hauj lwm kub, qee hom kev kho yuav sai sai thiab yuav tsum tau npaj rau. Yog tsis hais txog kev khiav hauj lwm cav, koj yuav tsis pom cov teeb meem no. Hom kev saib xyuas no tuaj yeem ua rau cov khoom tawg.

Cov ntawv luam tawm, kos duab, thiab schematics yog qhov tseem ceeb hauv kev txiav txim siab qhov chaw ntawm cov cuab yeej siv, txheeb xyuas nws cov khoom, thiab qhia qhov ua tau zoo ntawm kev ua haujlwm. Koj yuav siv peb hom kev luam tawm thiab kos duab hauv hluav taws xob teeb meem thiab kho.

●"As-built" blueprints thiab hluav taws xob kos duabqhia qhov chaw thiab qhov loj ntawm cov khoom siv hluav taws xob tswj, xws li cov keyboards thiab Circuit Court breakers, thiab qhov chaw ntawm cov xaim thiab cables. Cov khoom feem ntau yog sawv cev los ntawm cov qauv cim. Cov khoom tsis zoo lossis txawv txav feem ntau raug txheeb xyuas ntawm daim duab lossis hauv ib qho tseem ceeb ntawm hluav taws xob kos duab.

●Installation drawingsyog cov duab sawv cev ntawm cov khoom siv hluav taws xob muaj txiaj ntsig los nrhiav cov ntsiab lus sib txuas, txuas, thiab cov khoom tshwj xeeb. Cov cim hluav taws xob txheem tsis tas yuav tsum muaj, tab sis qee qhov yuav siv tau yooj yim.

●Schematics, lossis daim duab ntaiv, yog cov duab kos kom ntxaws uas qhia tias lub cuab yeej siv hluav taws xob li cas. Cov no vam khom rau cov qauv cim thiab tsis muaj lus piav qhia me ntsis.

Cov neeg tsim khoom cov ntaub ntawv tuaj yeem suav nrog kev teeb tsa thiab cov duab kos duab, nrog rau cov lus qhia thiab cov lus piav qhia txog kev ua haujlwm tshwj xeeb lossis kev ua haujlwm tsis zoo. Tag nrho cov ntaub ntawv no yuav tsum yooj yim rau koj.
