Puas yog nws ib txwm rau lub hauv paus tsis kam ntawm qhov qis - voltage them capacitor kom loj dua 1 moreohm?

Tsawg - voltage themactrial capactrors yog cov khoom siv tseem ceeb siv rau kev siv fais fab hluav taws xob hauv lub tshuab hluav taws xob. Lawv txoj kev ua haujlwm rwb thaiv tsev ncaj qha cuam tshuam rau kev ua haujlwm zoo ntawm cov khoom siv. Lub hauv paus tsis kam, raws li tus taw qhia tseem ceeb rau kev ntsuam xyuas cov kev rwb thaiv tsev rwb thaiv tsev, nws tus nqi loj yog qhov tseem ceeb tshaj plaws rau kev txiav txim siab kev noj qab haus huv ntawm cov khoom siv.

I. Rwb thaiv tsev yuav tsum tau kom tsawg- voltage themactration capacitors

1. Rwb thaiv tsev tsis kam ua qauv:

Lub rwb thaiv tsev tsis kam ntawm qhov tshiab nruab qis - voltage them nqi Capacitor yuav tsum muaj ntau dua los yog sib npaug rau 1000 MoGohms (1Gω)
Lub rwb thaiv tsev tsis kam ntawm kev ua haujlwm tsawg - verection} Voltage them nqi lub peev xwm yuav tsum muaj ntau dua los yog sib npaug rau 1 moegohm.

2. Kuaj cov mob:

Kev Ntsuas Ntsuas: 1000V Megohmeter
Kev sim ib puag ncig: Kub20 - 30 degree, txheeb ze cov av noo tsawg dua los yog sib npaug rau 85%
Kev sim ntev: 60 vib nas this, nyeem ntawm tus nqi ruaj khov tiav.

Ii. Kev tsom xam ntawm hauv av tsis kam ntau dua li 1 MEOHHM

1. Kev Txiaj Ntsig Txog Cov Zauv Qhov Tseem Ceeb:
1-10 Moohms: Hauv kev mob tseem ceeb, txhim kho kev saib xyuas yog yuav tsum tau ua.
{{010 - 100 Meyohms: Yeej tsim nyog tab sis tsis nyob hauv lub xeev zoo tagnrho
100 cov melohms thiab saum toj no: cov xwm txheej zoo

2. Kev ntsuam xyuas ntawm cov muaj peev xwm ua tau:

Kev laus: Kev laus laus ua rau los ntawm kev ua haujlwm ntev ntawm cov khoom siv
Ib puag ncig qhov: noo noo, plua plav, thiab lwm yam kev cuam tshuam ib puag ncig
Yawg noo noo: tsis ncav qib theem ntawm kev muaj dej noo heev.
Cov khoom siv rwb thaiv tsev muaj cov tsis zoo me ntsis.

III. Cov kws tshaj lij kev daws teeb meem

1. Kev txiav txim siab ua haujlwm:

1 {-} 5 Meohms: Rectification yog yuav tsum tau nyob rau hauv ib lub sijhawm txwv. Rov xeem dua yuav raug xeem nyob hauv 3 hlis.
5 - 10 egohms: nce saib xyuas zaus thiab rov ua dua nyob hauv 6 lub hlis
Qhov siab tshaj 10 Meohms: kev saib xyuas ib txwm muaj txaus.

2. Teem cov lus ceeb toom pib:

Ceeb Toom Daj: Hauv av tsis kam tau poob mus rau 5 mineohms.
Daim ntawv ceeb toom txiv kab ntxwv: hauv av tsis kam tau poob mus rau 3 MINOHHMS.
Kev Ceeb Toom Liab: Hauv av tsis kam poob mus rau 1 MEOHHM.
