Voltage Tester: phau ntawv no. Yuav ua li cas yog lub voltage tester mus yuav lub tswv yim
Ua hauj lwm nrog cov uas twb muaj lawm hluav taws xob, cabling thiab thaiv cov khoom poses ib tug uas yuav kom tau ib tug hluav taws xob kev raug mob. Yog vim li cas rau qhov no yog yooj yim - cov qhia zog ntawm them hais nyob rau hauv tus neeg xyuas pib tsis tau pom nrog tus liab qab qhov muag. Yog li ntawd, thaum lub sij hawm installation, lag luam thiab cov txij nkawm ntawm hluav taws xob khoom yuav tsum tau siv los mus ntsuam xyuas tus voltage tester
tseem ceeb heev yuav tsum tau
Voltage Tester - ib tug portable hluav taws xob ntaus ntawv npaj yuav qhia tau muaj cov tej zaum nyob rau hauv lub conductive chaw. Cov hluav taws xob mov yog tsis yog txhua txhua ntawm tej yog yus mus kov. Tam sim no sib ntaus sib tua cov neeg uas tam sim no theem, tab sis ib tug pes tsawg los yog hauv av hlau yog kev ruaj ntseg. Txawm li cas los, muaj reservations.
Yuav kom to taub li cas tej zaum yuav raug nyob rau hauv lub tsev-voltage tester, qhov uas yooj yim txoj kev uas yuav muab ib tug xov tooj ntawm cov piv txwv. Xav txog tej yam uas muaj ib tug yuav tsum tau nyob rau hauv lub li (li), uas nyob rau lub sij hawm muab ib tug neeg zej zog. Tseem qauv siv, uas cov vaj tse yog ua los ntawm cov hlau. Yuav ua li cas mus xyuas hais tias cov sab hauv circuits yog lawm, thiab lub plhaub Yog tsis muaj nro? Ua hauj lwm nrog xws li ib lub cuab tam, tom qab nws tau raug soj ntsuam - ib tug heev twv txiaj. Los yog, piv txwv li, yuav tau hloov ib lub teeb teeb nyob rau hauv lub teeb, iav teeb yog nqig, thiab tsuas yog lub plinth nyob rau hauv lub cartridge. Ntseeg electrician ua tau zoo rau xov, tus tes hloov qhov tiag tiag lov cov theem neeg xyuas pib thiab ib tug uas tsis yog-xoom, thiab ua siab loj ntswj cap? Nws yog doubtful! Tej piv txwv ntau ntau. Nrog nws tus kheej voltage tester, koj yeej ib txwm sai xyuas hauv kev kawm ntawm lub installation. Nyob rau hauv tas li ntawd, ntau cov qauv pub rau kev ntsuas ntawm qhov tam sim no tus nqi.
yooj yim nta
Yuav kom tau soj ntsuam xyuas cov hav zoov ntawm cov tej zaum (theem), muaj yog tsis muaj yuav tsum tau siv cov nyiaj mus yuav kim khoom.
Raws li ib tug tester mus xyuas lub voltage? Nyob rau Upper sab ntawm lub dielectric ntawm tus kov muaj ib tug tshwj xeeb hlau "penny." Mus xyuas lub saw seem yuav tsum yog siv ib tug ntswj ntsia hlau mus kov lub xeem ua rau yus, thiab ib tug ntiv tes - ib tug "tsib kopecks." Needless rau sting thaum nws tsis tau kov. Yog hais tias cov theem yog tam sim no, lub teeb illuminates sab hauv ntswj ntsia hlau. Thib ob lub npe ntawm screwdrivers - probes. Nws yog tsim voltages txog li 250 V.
Nws tsis pom zoo kom yuav cov uas pheej yig tshaj cov qauv, raws li nyob rau hauv cov ntaub ntawv ntawm rhuav tshem ntawm lub sab hauv resistor los yog uas tsis nyob rau hauv lub tswvyim yuav tau txais ib tug hluav taws xob kev poob siab. Ntau tshaj cov ntsiab tsis tau ncaj qha kev sib cuag nrog rau hauv Circuit Court feem. Sting ib tug ntswj ntsia hlau, koj cia li yuav tau siv tshaj rau neeg xyuas pib. Tsim los rau cov voltages mus txog 600 V.
Muaj kev hloov kho uas tsis yuav tsum tau so ntawm ib tug ntiv tes mus rau lub "tsib kopecks." Koj muaj peev xwm tsis tau tej teeb meem yuav ib tug voltage tester. Cov lus qhia raws li nws yuav tsum tau nyeem. Qhov no tsis tsuas cawm lub tsev los ntawm kev puas tsuaj, tab sis kuj yuav tiv thaiv tus neeg.
dual ntswj ntsia hlau
Nyob rau tib lub sij hawm yam cuab yeej saum heev narrowly tshwj xeeb. Yog hais tias koj xav tau, rau Piv txwv li, ua ib tug yooj yim ua hauj lwm - phasing, nws yog sib tsis tau vim hais tias ntawm lub xub ntiag ntawm xwb ib tug ncej. Nyob rau hauv cov ntaub ntawv no, koj yuav tsum xyuam xim rau ntau tshaj tester - ob chav pointer tsawg voltage. Structurally, nws yuav muab piv nrog ob tug screwdrivers, ib tug hlau ntawm kev twb kev txuas. Qhov siab tshaj plaws permissible voltage ntawm 1 kV. Nqe - los ntawm 100 rubles.
Tham seb mus ntsuas qhov voltage tester ntawm no hauv chav kawm ntawv. Plev-electrode ib tug ntawm cov yuav tsum tau kov rau hauv Circuit Court nyob rau hauv kev xeem qhov chaw, thiab lwm yam - mus rau lub "lub ntiaj teb." Qhov no tej zaum yuav muaj av neeg xyuas pib thiaj li txaus ntshai tej zaum tsis ntws los ntawm lub ntaus ntawv.
qhia
Cov tom ntej no hauv chav kawm ntawv ntawm xws li yog voltage ntsuas. Qhov zoo tshaj plaws lub npe hu qauv ntawm "Tiv tauj" Ukrainian chaw tsim tshuaj paus. tus nqi pib los ntawm 400 rubles. Structurally, cov testers vaguely zoo li ob ntswj ntsia hlau, tab sis muaj ntau ntau kev nta.
Yuav ua li cas mus nrhiav tau ib tug nyob hlau
Xav txog yuav ua li cas ib tug tester mus xyuas lub voltage. Ib tug ntawm cov probes ntawm tus dais koj yuav tsum mus kov qhov ntsuam xyuas qhov chaw installation, thiab ntiv tes xoo - Ph mus rau lub electrode ntawm lub cev. Yog hais tias lub sib nug xov LED teeb, ces tus neeg xyuas pib yog energized. Txawm li cas los, muaj ib tug caveat, uas yog heev zoo paub rau cov neeg uas paub yuav ua li cas mus ua hauj lwm tester voltage ntawm no hom. Nws cov lus dag nyob rau hauv lub fact tias lub xeem theem ntawm Ph yog tsis ib txwm muaj tseeb, raws li cov zaj lus tim khawv yuav cuam tshuam cuam los ntawm ze rau tam sim no-nqa conductors. Yuav kom paub meej, muaj ob uas nyob ib sab ntawm tej, ib tug ntawm cov uas yog energized thiab lwm yam energized. Yog hais tias koj tsis paub yuav ua li cas mus ua hauj lwm tester voltage nyob rau hauv kom meej, xyuas ob conductors los ntawm kov tau lawv thiab Ph electrode hloov tawm hais tias raws li cov hais lawv yog ob leeg theem.
Irregularities ntawm lub tester pointer
Cov specification hais tias tam sim no ntws los ntawm lub Circuit Court ntaus ntawv thaum xyuas muaj peev xwm 220 yog tsis ntau tshaj 10 ma. Uas yog, yog tias koj kov ib tug ntawm cov probes mus rau lub site ntawm lub hwj chim nroj tsuag, uas yog nyob rau hauv voltage, lub ammeter kev cob cog rua rau lwm sojntsuam, cov saum toj no yuav qhia cov tam sim no tus nqi.
Mus pib nrog cov "hu"
Tag nrho cov kev daws teeb meem nyob rau hauv uas ob units sib thooj, los ntawm ib tug hlau, yog muaj yus. Ib tug ntawm lawv drawbacks - ib tug tseem ua kom cov txuas xyuas pib nyob rau pom plhaub ntseeg. Yog li ntawd, thaum khij rau theem ntawm Ph pom zoo sojntsuam txog cov kev thaiv uas lub active electrode yog muab tso rau. Nyob rau hauv cov ntaub ntawv no, lub LED yuav ua hauj lwm, txawm yog hais tias tus hlau yog puas ntsoog. Txawm li cas los, ua ntej ua ntsuas yuav tsum tau txuas lub ntaus ntawv mus rau lub network thiab los tuav nws 20 - thaum lub sij hawm lub sij hawm no them nrog hwj chim qhov twg los. Ces koj yuav tsum tau txuas nrog txhua lwm yam probes. Yog hais tias ib tug hlau, lub LED teeb "xeem."
universal lub cuab tam
Nyob rau hauv tas li ntawd rau tag nrho cov ntawm cov pab kiag li lawm, muaj ib yam zoo - multimeters. Tej zaum qhov no yog lub zoo meej tshaj plaws voltage tester. Yuav ua li cas yuav siv nws, peb yuav tam sim no piav qhia txog. Tus nqi ntawm cov feem ntau pheej yig qauv pib los ntawm 300 rubles. Lag luam yog piav nyob rau hauv lub nrog phau ntawv, uas yuav tsum tau muaj. Yog hais tias peb tham txog kev kuaj cov voltage, ib tug hlau yuav tsum tau txuas ib COM chaw nres nkoj, lwm yam - los V. Ces, teem lub mus rau 750 AC (alternating tam sim no yam, cov kev txwv ntawm 750 V) hom thiab kov probes mus rau lub "ntiaj teb" thiab lub cheeb tsam raug audited.
tshawb pom
Yog li, nws yog tsis yooj yim sua kom muab ib tug ntshiab kev pom zoo rau cov kev xaiv ntawm kev ntsuas. Txhua yam nws yog nyob ntawm lub ntau yam kev pab raws qib uas tau teem tseg yuav nyob. Yog hais tias muaj yog nyiaj ntxiv yuav zoo tshaj plaws mus yuav ib tug universal multimeter.
