Qhov Sib txawv ntawm Kev Ntsuas Cov Txheej Txheem Ntawm Cov Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob thiab Cov Khoom Siv Hluav Taws Xob
(1) Kev Ntsuas Cov Txheej Txheem Kev Ruaj Ntseg Ua Haujlwm Tester
Rwb thaiv tsev Resistance Tester yog txhawm rau kuaj cov qib ntawm rwb thaiv tsev ntawm theem, txheej thiab nruab nrab cov ntsiab lus ntawm cov hlau thiab cables.Qhov siab dua qhov ntsuas tus nqi, qhov zoo dua qhov kev ua haujlwm rwb thaiv tsev.Lub rwb thaiv tsev tiv thaiv tuaj yeem ntsuas tau los ntawm UMG2672 Electronic Megohmmeter.
(2) Test Method of Grounding Resistance Tester
Lub Grounding Resistance Tester yog ib qho khoom siv hluav taws xob uas tshawb pom seb qhov kev tiv thaiv hauv av puas tsim nyog.Txoj Kev Ntsuas Kev Ntsuas Kev Ntsuas Kev Ntsuas Qhov Ntsuas yog qhov khoom siv hluav taws xob txuas nrog tib lub peev xwm los ntawm lub ntiaj teb, thiab nws yog qhov kaw ntawm cov xov hlau tsis zoo lossis xob laim rau lub ntiaj teb.Tus nqi ntsuas los ntawm Grounding Resistance Tester yog ib qho kev ntsuas zoo los ua kom muaj kev nyab xeeb ntawm tus kheej.Koj tuaj yeem xaiv DER2571 Digital Grounding Resistance Tester tsim los ntawm WeiA Fais Fab.
Plaub, Txoj Cai Sib Txawv Ntawm Cov Hluav Taws Xob Resistance Tester Thiab Av Resistance Tester
(1) Lub hauv paus ntsiab lus ntawm Rwb thaiv tsev Resistance Tester
Thaum Cov Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Siv Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob, DC Voltage U yog siv rau lub rwb thaiv tsev.Lub sijhawm no, Ib qho tam sim no hloov pauv nrog lub sijhawm, thiab thaum kawg Tens mus rau tus nqi ruaj khov.
Feem ntau, Tam sim no ntawm Ib qho Kev Ntsuas Hluav Taws Xob Hluav Taws Xob yog qhov suav ntawm Capacitance Current, Absorption Current thiab Conduction Tam Sim No.Capacitive Tam sim no Ic, Nws qhov ceev nrawm nrawm heev;Absorption tam sim no Iaδc, Nws lwj qeeb qeeb dua li tam sim no Capacitive;Kev coj ua tam sim no Inp, Nws Nyuaj kom ruaj khov nyob rau lub sijhawm luv luv.
Thaum lub sij hawm qhov kev xeem siv lub rwb thaiv tsev tiv thaiv Tester, Yog hais tias lub rwb thaiv tsev tsis damp thiab qhov nto yog huv si, lub Transient tam sim no Cheebtsam Ic thiab Iaδc yuav sai sai lwj mus rau xoom, tawm tsuas yog ib tug me me conduction tam sim no inp mus dhau, vim hais tias cov rwb thaiv tsev kuj yog inversely. Raws li qhov cuam tshuam rau qhov tam sim no, cov rwb thaiv tsev tiv thaiv yuav nce nrawm thiab ruaj khov ntawm tus nqi loj.Conversely, Yog hais tias lub rwb thaiv tsev yog damp, qhov conduction tam sim no nce tseem ceeb, txawm sai dua qhov pib tus nqi ntawm lub nqus tam sim no Iaδc, lub sij hawm tam sim no cov khoom yog txo qis, thiab cov rwb thaiv tsev kuj nqi tsawg heev, thiab nws hloov tau zoo heev nrog lub sij hawm.Micro.
Yog li ntawd, nyob rau hauv qhov kev sim ntawm lub rwb thaiv tsev Resistance Tester, cov ntsiab lus noo noo ntawm lub rwb thaiv tsev yog feem ntau txiav txim los ntawm lub absorption ratio.Thaum Qhov Kev Ntsuas Qhov Ntsuas Zoo Tshaj 1.3, Nws qhia tau tias qhov rwb thaiv tsev zoo heev.Yog tias qhov kev nqus nqus yog ze rau 1, nws qhia tau tias cov rwb thaiv tsev yog damp.
(2) Txoj Cai ntawm Grounding Resistance Tester
Grounding Resistance Tester tseem hu ua Grounding Resistance Measuring Instrument, Grounding Shaker.Lub hauv paus ntsiab lus ntawm Kev Ntsuas Kev Ntsuas hauv av yog kom tau txais qhov txiaj ntsig hauv av "Rx" Los ntawm AC tas li tam sim no "I" nruab nrab ntawm av hluav taws xob "E" Thiab Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob "H(C)" Ntawm Cov Khoom Hauv Kev Xeem, Thiab Qhov Kev Pom Zoo Pom Pom Qhov Qhov Sib Txawv "V" Ntawm Cov Hluav Taws Xob "E" Thiab Kev Ntsuas Electrode "S(P)".
