Antistatic daim kab xev nrhiav kom tau
Ua ntej, point-to-point resistance thiab system tsis kam mus kuaj
Qhov kub thiab ntsuas huab cua thaum lub sijhawm ntsuas yog: ntsuas kub: 23 ± 3 C, txheeb ze cov av noo: 40% - 60% ± 5%.
Txheeb xyuas cov cuab yeej hauv qab sim thiab lub tshuab hluav taws xob megger kom huv. Yog tias tsim nyog, ntxuav nrog daim ntaub mos muag dampened nrog 70% isopropyl cawv.
Muab cov qauv coj los ntsuas rau ntawm cov rwb thaiv tsev, thiab tom qab ntawd ntxig rau lub tshuab hluav taws xob micro-ntsuas lub khob rau hauv qhov dav ntawm qhov megohmmeter raws li xim.
Lub tshuab hluav taws xob mini yog tusyees nias rau ib nrab, thiab 10V cov ntaub ntawv ntawm lub megohmmeter kaw rau kev kuaj. Yog tias nyeem ntawv yog <1.0 ×="" 10="" ^="" 7="" ohms,="" txuas="" ntxiv="" qhov="" kev="" sim="" nrog="" cov="" ntawv=""> Yog tias nyeem ntawv yog> 1.0 × 10 ^ 7 ohm, hloov nws nrog 100V. Cov ntaub ntawv rau kuaj. Tos rau qhov kev nyeem ntawv ruaj khov tus nyeem ntawv kom ua tiav qhov kev xeem. Siv cov txheej txheem sib xyaw ua ntau qhov chaw nyob ntawm tus qauv coj mus kuaj rau kev sim.
Thib ob, kev sib txhuam voltage ntsuas
Kev txhuam txhuam yog siv rau kev tsim hluav taws xob ua kom muaj hluav taws xob thiab qhov sib txhuam hluav taws xob hluav taws xob tau sim siv qhov tsis muaj sib tiv toj ntawm electrostatic voltmeter. Kev sib txhuam hluav taws xob txhuam hluav taws xob yog qhov sib npaug, nrog txoj kab uas hla ntawm 50mm mus rau 60mm, qhov hnyav ntawm 1kg, qhov ntim ntawm ntau dua li 1 × 10 ^ 13 ohms, thiab yog qhwv nrog cov ntaub rwb thaiv tsev siab nylon (qhov chaw tiv thaiv tsis tsawg dua 1 × 10 ^ 13 ohms) txhawm rau kom muaj kev sib txhuam. coefficient. Thaum lub sijhawm ntsuas, lub tshuab hluav taws xob txhuam pib pib txhuam cov txhuam hluav taws xob nrog lub ntsuas kom ntsuas, thiab txoj kev sib txhuam ib leeg tau nres 20 zaug (sijhawm 20 s), thiab txhuam kev sib txhuam hluav taws xob hluav taws xob tau kuaj nrog qhov tsis sib chwv. ntsuas hluav taws xob voltmeter hauv 10 s. (Npav SJT 10694-2006)
Siv sijhawm ntev ntawm tus qauv coj mus kuaj thiab muab tso rau hauv pawg thawj coj saib rwb thaiv tsev, thiab txuas cov hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob hauv av mus rau qhov chaw sib tshooj. Qhib lub ntsuas hluav taws xob voltmeter zoo li qub thiab pib ua haujlwm pib qhov hluav taws xob voltmeter zoo li qub mus rau xoom raws li cov lus qhia ua haujlwm ntawm lub rooj. Tso cov kev sojntsuam ntawm qhov ntsuas hluav taws xob qhov ntsuas hluav taws xob ze rau cov qauv kom ntsuas 2 cm. Tom qab nyeem ntawv tseem ruaj khov, nyeem cov ntawv nyeem thiab sau cia. Yog hais tias qhov hluav taws xob voltmeter zoo li infrared-nkag siab, kho qhov kev ncua deb ntawm qhov ntsuas hluav taws xob thiab qhov ntsuas qhov ntsuas, thiab pib pib nyeem tom qab ob lub qhov hluav taws xob sib txuas ua ke rau ib qho infrared taw tes. Thaum kuaj cov hluav taws xob hluav taws xob zoo li qub ntawm qhov sib txhuam, kho lub ntsuas voltmeter mus rau qhov chaw deb uas haum raws li cov sib txawv voltmeter. Rub cov qauv mus rau kev sim nrog cov hnab looj tes electrostatic rau li 20 zaus, tom qab ntawd nyeem thiab sau cov kev nyeem ntawv siab tshaj plaws ntawm voltmeter.
Kev txhuam txhuam hluav taws xob hluav taws xob thiab qhov ntsuas hluav taws xob zoo: txiav txim siab raws ntau qib EHA, qib 1 <100v, qib=""><>
Thib peb, ntsuas hluav taws xob sib cais
Qhov av ntawm txoj kab hluav taws xob ntawm qhov hluav taws xob voltmeter zoo li qub thiab txhim kho tus qauv coj los ntsuas qhov ntsuas cov kab xev.
Ceev nrawm nrawm rau daim kab xev thiab coj cov voltmeter kaw ze thiab ruaj ntseg tus qauv los ntsuas ntawm daim kab xev txhawb nqa.
Separation voltage txheem: txiav txim siab raws ntau qib EHA, qib 1 <100v qib=""><>
Cov qauv ntxiv raug sim ua qhov no.
Yog tias sim nrog tus ntsuas ntsuas nyiaj them nqi, thawj kho cov hom rau "Field Meter" thiab tshem daim phaj electrode. Dua daim kab xev kom raug sim thiab muab tso dua lub ntsuas, mam li nyeem thiab sau rau hauv KV / M.
