Yuav Ua Li Cas Kom Siv Siab -Voltage Testing Instruments?
Tso lus
Koj tab tom tuav - kev pheej hmoo ua haujlwm xws li siab - cov khoom siv hluav taws xob ntsuas. Txhua kauj ruam ntawm kev ua haujlwm yog cuam tshuam nrog kev nyab xeeb ntawm tus kheej thiab khoom siv. Nug cov lus nug ceev faj yog qhov qhia txog kev tshaj lij, thiab qhov no yog qhov qhuas.
Cov ntsiab cai tseem ceeb rau Kev Siv Siab -Voltage Testing Instruments
Kev nyab xeeb ua ntej, kev ua haujlwm tau zoo, thiab cov ntaub ntawv raug yog peb tus ncej ntawm kev ntsuas siab -voltage. Cov cuab yeej sib txawv muaj kev siv sib txawv, thiab cov txheej txheem ua haujlwm yuav tsum tau ua raws li lawv hom. Cov hauv qab no yog cov qauv qhia kev khiav hauj lwm raws li cov khoom siv ntsuas hluav taws xob siab - cov khoom siv ntsuas hluav taws xob, muab tso ua ke raws li kev tswj hwm kev nyab xeeb hluav taws xob.
Kev Siv Cov Kauj Ruam rau Kev Tiv Thaiv Voltage Testers (tseem siv tau rau Kev Ntsuas Kev Ntsuas Hluav Taws Xob)
Cov cuab yeej no yog siv los txheeb xyuas qhov rwb thaiv tsev lub zog ntawm cov khoom siv hluav taws xob nyob rau hauv ib qho kev ntsuas voltage. Nws yog feem ntau siv rau hauv kev sim ntawm transformers, switchgear, cables, thiab lwm yam.
Kev Npaj Kev Nyab Xeeb Ib puag ncig
Qhov chaw kuaj yuav tsum qhib, tsis muaj cov neeg ua haujlwm lossis cov khoom siv hlau tsis pub dhau 1 meter. Ib qho insulating lev nrog lub thickness ntawm ntau dua los yog sib npaug li 5 hli yuav tsum tau muab tso rau hauv av.
Tshaj tawm "High-Voltage Testing, Do Not Approach" ceeb toom cov paib thiab teeb tsa kab ceeb toom.
Cov neeg ua haujlwm yuav tsum hnav cov hnab looj tes insulating nrog lub zog tiv taus ntau dua lossis sib npaug ntawm 10kV thiab cov khau insulating nrog lub zog tiv taus ntau dua lossis sib npaug ntawm 6kV. Cov plaub hau ntev yuav tsum tau khi, thiab cov hniav nyiaj hniav kub raug txwv.
Cov khoom siv thiab cov khoom kuaj xyuas:
Tshawb xyuas cov khoom siv: xyuas kom meej tias qhov siab -voltage output wire (liab) thiab grounding wire (dub) tsis puas thiab cov plugs muaj kev sib cuag zoo.
Ntsuas Tus Kheej-Test: Tom qab lub hwj chim qhib, saib lub vijtsam zaub rau kev ua haujlwm ib txwm muaj. Teem lub siab -voltage adjustment knob rau 0, luv-circuit lub output davhlau ya nyob twg thiab lub grounding davhlau ya nyob twg, thiab pib qhov kev xeem. Paub meej tias qhov tso tawm tam sim no yog 0 lossis ze rau 0.
Parameter Chaw:
Teem lub ntsuas hluav taws xob (piv txwv li, 3.5kV), lub sijhawm sim (piv txwv li, 60 vib nas this), thiab cov dej xau tam sim no txwv (piv txwv li, 5mA).
Xaiv "Timed" lossis "Manual" hom: "Timed" feem ntau siv hauv cov kab ntau lawm, thaum "Manual" tuaj yeem siv los tswj cov txheej txheem kev txhawb zog rau kev tshawb fawb tshawb fawb.
