Lub hauv paus ntsiab lus ntawm DC resistance testing yog dab tsi? Wuhan UHV tshwj xeeb hauv kev tsim khoomDC tiv thaiv testersnrog ntau yam khoom xaiv. Thaum tab tom nrhiav DC qhov ntsuas ntsuas, xaiv Wuhan UHV.
CovDC tiv thaiv testerrau transformer windings yog ib qho tseem ceeb ntawm cov khoom siv rau kev hloov pauv tom qab kev xa khoom, kev kho loj, thiab kev hloov pauv rau cov kais hloov pauv. Los ntawm kev ntsuas qhov DC tsis kam ntawm transformer winding, vuam lossis kev sib txuas zoo ntawm cov hlau lead, muaj qhov sib cuam tshuam luv luv lossis qhib circuits hauv winding, thiab kev sib cuag zoo ntawm tus kais hloov pauv tuaj yeem kuaj xyuas.
DC tsis kam ntawm transformers yog cov khoom ntsuas tsim nyog rau ib nrab- cov khoom tiav thiab tiav hauv kev tsim khoom siv hluav taws xob, kev kuaj xyuas lub Hoobkas, kev teeb tsa, kev kho loj, kev hloov pauv rau cov hloov pauv, kev xa mus kuaj, thiab kev ntsuas kev tiv thaiv los ntawm lub tuam tsev fais fab. Nws yog ib qho ua tau los xyuas qhov zoo ntawm cov vuam zoo ntawm cov pob qij txha winding thiab seb puas muaj qhov tig los tig luv luv hauv lub winding. Nws tseem tuaj yeem txheeb xyuas seb qhov ntau txoj haujlwm ntawm lub tshuab hluav taws xob hloov pauv puas muaj kev sib cuag zoo, txawm tias qhov tseeb ntawm qhov hloov pauv hloov pauv qhov sib luag ntawm txoj haujlwm qhia, seb cov hlau lead puas tawg, thiab seb puas muaj cov xov hlau tawg thaum ntau cov xov hlau raug mob ua ke. Yuav kom ua tau raws li qhov xav tau ntawm kev ntsuas ceev ntawm transformer DC tsis kam, peb lub tuam txhab tau tsim UHV-100ADC tiv thaiv tester. Cov cuab yeej no siv cov cuab yeej siv hluav taws xob tshiab, uas muaj cov yam ntxwv ntawm qhov me me, lub teeb yuag, cov zis loj tam sim no, rov ua tau zoo, muaj zog tiv thaiv - muaj peev xwm cuam tshuam, thiab ua tiav kev tiv thaiv. Lub tshuab tag nrho yog tswj hwm los ntawm lub siab - ceev microcontroller, nrog rau qib siab ntawm automation thiab tsis siv neeg tso tawm thiab tawm lub tswb ua haujlwm. Cov cuab yeej muaj qhov ntsuas qhov tseeb, kev ua haujlwm yooj yim, thiab tuaj yeem ua tiav kev ntsuas nrawm ntawm transformer ncaj qha tsis kam.
CovDC tiv thaiv testeryog lub cim tshiab ntawm transformer DC tsis kam ntsuas ntsuas, uas tuaj yeem xaiv qhov ntsuas tam sim no raws li cov qauv sib txawv ntawm lub zog hloov hluav taws xob thiab tso saib cov txiaj ntsig ntawm qhov ceev tshaj plaws. DC resistance tester muaj lub luag haujlwm xws li them nyiaj thiab tso tawm cov ntsuas, thiab kev siv lub LCD ua rau lub ntsuas hluav taws xob muaj tib neeg zoo - tshuab interface, ua rau nws nyiam cov khoom siv rau DC tsis kam kuaj ua haujlwm. DC resistance tester yog qhov siab -cov khoom hloov pauv rau DC ib leeg thiab ob sab caj npab choj. Cov cuab yeej siv cov cuab yeej siv hluav taws xob hloov pauv siab heev, thiab nws qhov ntsuas ceev yog ntau dua 100 npaug sai dua li ntawm tus choj. Cov khoom siv qhia txog qhov ntsuas ntsuas ntawm plaub thiab ib nrab tus lej LCD kua siv lead ua kua zaub, thiab peb thiab ib nrab tus lej LCD kua siv lead ua qhia qhov ntsuas kub lossis ntsuas tus nqi tam sim no, kov yeej qhov tsis zoo ntawm lwm yam khoom zoo sib xws uas tsis yooj yim nyeem hauv qab hnub ci. Nyob rau tib lub sijhawm, nws muaj qhov tsis siv neeg arc extinguishing muaj nuj nqi. 3A DC tiv thaiv sai tester muaj qhov zoo ntawm kev ntsuas ceev ceev, qhov tseeb siab, cov khoom siv nkag siab, muaj zog tiv thaiv- muaj peev xwm cuam tshuam, me me, siv hluav taws xob tsawg, ruaj khov thiab txhim khu kev qha cov ntaub ntawv, thiab tsis cuam tshuam los ntawm tib neeg yam. Lub ntsuas hluav taws xob tau nruab nrog lub pob roj teeb rov qab (12V), uas tuaj yeem siv rau ob qho tib si AC thiab DC, ua kom yooj yim rau ntawm - qhov chaw thiab kev sim.
Daim ntawv thov ntawm DC resistance tester
DC grounding resistance tester yog ib qho cuab yeej zoo tshaj plaws rau kev ntsuas DC tsis kam ntawm ntau yam inductive loads xws li lub zog hloov hluav taws xob, lub cev muaj zog loj, thiab hloov pauv, nrog rau kev sib cuag ntawm qis -voltage keyboards thiab qhov cuam tshuam ntawm cov xov hlau, cables, lossis welds.
Cov kev ceev faj
1. Ua ntej kuaj qhov tsis muaj -load kais hloov pauv ntawm lub tshuab hloov pauv, nws yuav tsum rov pib dua. Tom qab qhov tso tawm tiav lawm, lub tswb nrov yuav tsum nres ntau dua 10 vib nas this ua ntej hloov tus kais hloov pauv.
2. Ua ntej disconnecting, nco ntsoov tos kom qhov tso tawm kom tiav thiab lub tswb nrov kom nres. Nws yog qhov zoo tshaj kom tos ntev dua 10 vib nas this ua ntej txiav tawm kom ntseeg tau tias cov nqi raug tso tawm tag nrho.
3. Thaum xaiv qhov tam sim no, xa mus rau ntau yam hauv kab lus qhia tshwj xeeb thiab tsis txhob siv nws dhau lossis qis dua qhov ntau. Thaum qhov tam sim no tshaj tus nqi preset, qhov ntsuas tseem nyob rau hauv lub xeev "them nqi". Thaum qhov ntau yam tsis txaus, nws qhia 'tam sim no tsawg dhau'. Thaum ob lub xeev no tshwm sim, lees paub qhov ntau thiab xaiv qhov tsim nyog tam sim no rau kev sim.
4. Ua tib zoo saib xyuas qhov ntau thaum siv txoj kev sib nqus pab. Vim hais tias ob lub siab -voltage coils txuas nrog nyob rau hauv parallel thiab ib qho yog txuas nrog rau hauv series, 1.5 npaug ntawm qhov kev tiv thaiv ntawm high-voltage coil yog ntxiv rau tag nrho cov kev ntsuam xyuas Circuit Court, thiab ntau yam kev xaiv yuav tsum tau muab rau hauv tus account. Yog tias cov zis tam sim no tsis tuaj yeem ncav cuag tus nqi teev lossis tsis ruaj khov thaum siv dhau qhov ntau.
5. Thaum cov kev sib cuag luv luv ntawm peb lub xov hlau ntawm txoj kev sib nqus pab tau raug tshem tawm tom qab tso tawm, tej zaum yuav muaj qhov seem tam sim no, uas yuav ua rau hluav taws kub hnyiab thiab tawm thaum tshem tawm. Qhov no yog ib qho tshwm sim.
6.Thaum txuas cov kev sim clamp mus rau cov hlau lead tawm davhlau ya nyob twg ntawm transformer winding, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov hlau lead tawm davhlau ya nyob twg raug rau huab cua ntev, thiab qhov saum npoo ntawm cov hlau lead tawm davhlau ya nyob twg yog them nrog oxide zaj duab xis, uas yuav ua rau tsis ruaj khov lossis tsis raug ntsuas. Yog li ntawd, thaum xaim, yuav tsum tau them nyiaj rau kev tu cov oxide zaj duab xis, los yog tom qab txuas lub xeem clamp mus rau cov hlau lead tawm davhlau ya nyob twg, twist lub xeem clamp vigorously ob peb zaug txiav los ntawm oxide zaj duab xis los xyuas kom meej kev twb kev txuas zoo.
