Lub Rwb thaiv tsev Resistance Tester tuaj yeem siv los ntsuas qhov ntsuas tus nqi ntawm ntau yam khoom siv rwb thaiv tsev thiab cov rwb thaiv tsev tiv thaiv ntawm Transformers, Motors, Cables, Cov khoom siv hluav taws xob, thiab lwm yam hauv qab no peb yuav tham txog qee yam teeb meem.
01
Qhov Output Short-Circuit Tam Sim No Ntawm Cov Hluav Taws Xob Resistance Tester txhais li cas?
Ntev Cables, Motors Nrog Ntau Windings, Transformers, thiab lwm yam yog cais raws li Capacitive Loads.Thaum ntsuas qhov tsis kam ntawm cov khoom zoo li no, cov zis luv luv-Circuit tam sim no ntawm Cov Hluav Taws Xob Hluav Taws Xob Resistance Tester tuaj yeem cuam tshuam qhov kev tiv thaiv sab hauv ntawm Internal Output High-Voltage Source ntawm Megger..
02
Vim li cas thiaj siv Sab Nraud "G" Xaus los ntsuas qhov siab dua
Qhov "G" Terminal (Shielding Terminal) ntawm sab nrauv, Nws txoj haujlwm yog txhawm rau tshem tawm qhov cuam tshuam ntawm cov av noo thiab av hauv qhov ntsuas qhov ntsuas ntawm qhov ntsuas tau.Thaum ntsuas qhov kev tiv thaiv siab dua, yog tias koj pom tias cov txiaj ntsig nyuaj kom ruaj khov, koj tuaj yeem txiav txim siab siv G Terminal txhawm rau tshem tawm qhov yuam kev.
03
Ntxiv rau Kev Ntsuas Kev Tiv Thaiv, Vim Li Cas Peb Yuav Tsum Ntsuas Qhov Ntsuas Qhov Ntsuas Thiab Qhov Ntsuas Polarization?
Hauv Kev Ntsuas Hluav Taws Xob, Cov Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Ntawm Ib Lub Sijhawm Tsis tuaj yeem cuam tshuam tag nrho cov txiaj ntsig thiab qhov tsis zoo ntawm Cov Hluav Taws Xob Ua Haujlwm ntawm Cov Qauv Ntsuas.Ntawm qhov one tes, vim yog cov khoom siv rwb thaiv tsev ntawm tib lub luag haujlwm, qhov rwb thaiv tsev tsis zoo tshwm sim thaum lub ntim loj, thiab cov rwb thaiv tsev tsis zoo tshwm sim thaum lub ntim me me.Loj.Ntawm qhov tod tes, cov khoom siv rwb thaiv tsev muaj cov txheej txheem them nqi (DAR) thiab Polarization (PI) txheej txheem tom qab siv cov hluav taws xob siab.
04
Vim li cas thiaj tuaj yeem Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Ua Hluav Taws Xob Ua Hluav Taws Xob DC High Voltage
Raws li Txoj Cai ntawm DC hloov dua siab tshiab, Ib qho hluav taws xob rwb thaiv tsev tiv thaiv Tester Powered los ntawm ob peb lub roj teeb tau ua tiav los ntawm Booster Circuit.Qhov qis zog muab hluav taws xob Voltage yuav nce mus rau ib tug siab dua tso zis DC Voltage.Lub High Voltage Generated yog siab dua tab sis lub zog tso zis qis dua.
Kev Ceeb Toom Rau Kev Siv Hluav Taws Xob Resistance Tester
1. Ua ntej ntsuas, ua qhov qhib Circuit Court thiab luv Circuit Court Test ntawm lub rwb thaiv tsev Resistance Tester los xyuas seb lub rwb thaiv tsev Resistance Tester puas zoo li qub.Kev ua haujlwm tshwj xeeb yog: Qhib Ob Qhov Txuas Txuas Txuas, Tus pointer ntawm lub viav vias tuav yuav tsum taw tes rau qhov tsis muaj tseeb, thiab tom qab ntawd luv ob txoj hlua txuas, tus taw tes yuav tsum taw tes rau xoom.
2. Cov cuab yeej nyob rau hauv kev sim yuav tsum tau txiav los ntawm lwm qhov chaw fais fab.Tom qab kev ntsuas tiav lawm, Cov cuab yeej nyob rau hauv kev sim yuav tsum tau muab tso tawm tag nrho (kwv yees li 2 ~ 3 feeb) txhawm rau tiv thaiv cov khoom siv thiab kev nyab xeeb ntawm tus kheej.
3. Lub rwb thaiv tsev tiv thaiv Tester thiab cov cuab yeej nyob rau hauv kev sim yuav tsum tau sib cais thiab txuas sib cais los ntawm ib lub xaim, thiab qhov saum npoo ntawm lub Circuit Court yuav tsum tau muab ntxuav thiab qhuav kom tsis txhob muaj teeb meem tshwm sim los ntawm cov rwb thaiv tsev tsis zoo ntawm cov hlau.
4. Thaum lub sij hawm co co, muab lub rwb thaiv tsev tiv thaiv Tester nyob rau hauv ib tug kab rov tav txoj hauj lwm, thiab tsis muaj luv luv Circuit Court ntawm lub Terminal nyees khawm raug tso cai thaum lub tuav yog dov.Thaum kuaj cov capacitors thiab cables, nws yog ib qho tsim nyog yuav tsum tau txiav cov xov hlau thaum lub crank tuav yog dov, txwv tsis pub tus nqi rov qab yuav ua rau lub rwb thaiv tsev tiv thaiv tester.
5. Thaum viav vias tus tuav, nws yuav tsum tau qeeb dua thiab nrawm dua, thiab nrawm dua mus txog 120r / min, thiab xyuam xim tiv thaiv hluav taws xob poob siab.Thaum lub sij hawm viav vias txheej txheem, thaum tus pointer tau mus txog xoom, nws tsis tuaj yeem txuas ntxiv viav vias kom tiv thaiv kom tsis txhob muaj cua sov thiab puas tsuaj rau lub kauj hauv Watch.
6. Txhawm rau tiv thaiv kom tsis txhob muaj qhov dej tsis haum ntawm cov cuab yeej hauv kev sim, thaum siv cov khoom siv hluav taws xob tiv thaiv hluav taws xob, cov txheej txheem nruab nrab ntawm cov cuab yeej nyob rau hauv kev sim (xws li cov rwb thaiv tsev sab hauv nruab nrab ntawm cov tub ntxhais cable) yuav tsum tau txuas nrog lub nplhaib tiv thaiv.
7. Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob uas tsim nyog yuav tsum tau xaiv nyob ntawm qhov ntsuas hluav taws xob ntawm cov khoom hauv qab kev sim.Feem ntau, Rau cov khoom siv nrog qhov ntsuas hluav taws xob qis dua 500 volts, xaiv qhov ntsuas hluav taws xob tiv thaiv hluav taws xob ntawm 500 volts lossis 1000 volts;Rau cov khoom siv nrog qhov ntsuas hluav taws xob ntawm 500 volts thiab saum toj no, xaiv qhov ntsuas hluav taws xob tiv thaiv hluav taws xob ntawm 1000 txog 2500 volts.Nyob rau hauv qhov kev xaiv ntawm qhov ntsuas qhov ntsuas, kev saib xyuas yuav tsum tsis txhob ua kom qhov ntsuas ntsuas qhov ntsuas ntau dhau ntawm qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas ntawm cov cuab yeej hauv qab ntsuas kom tsis txhob muaj qhov yuam kev loj hauv kev nyeem ntawv.
8. Tiv thaiv kev siv cov rwb thaiv tsev tiv thaiv kev ntsuas ntsuas hauv huab cua xob laim lossis cov khoom nyob ze nrog cov neeg siv hluav taws xob siab.
