A High Voltage Divideryog cov circuit tshwj xeeb tsim kom muaj feem txo qis voltages rau qis dua, qib ntsuas thaum saib xyuas kev nyab xeeb thaum muaj kev nyab xeeb, thiab kev ntseeg tau. Ntawm no yog ib qho kev sib tsoo tsim:
Qhov tseem ceeb Cheebtsam & hom
-
Tiv Yaug Dividers:
-
Siv high-voltage de kom haum rau lub hwj chim dissipation thiab voltage witort lub peev xwm.
-
Qhov zoo tagnrho rau DC lossis tsawg zaus AC daim ntaub ntawv thov.
-
Cov neeg tawm tsam feem ntau tau npaj hauv koob coj los faib hluav taws xob tusyees, tiv thaiv kev tiv thaiv lossis tawg.
-
-
Muaj Peev Xwm Sib Raug:
-
Cov neeg ua haujlwm capacitors faib ua hluav taws xob ac voltages raws li referance (impedance piv).
-
Siv tau rau AC cov tshuab, raws li lawv txo qis zog poob piv rau cov diamonders tawm tsam.
-
-
Sib xyaw ua ke-capacitive:
-
Siv rau cov ntawv thov yuav tsum muaj ob qho DC thiab AC scaling (piv txwv li, oscilloscope kev ua haujlwm nrog cov nyiaj them zaus).
-
Kev txiav txim siab tsim
-
Kev xyuas xim:
-
Rwb thaiv tsev, creepage / tshem tawm kev mus deb, thiab cov qauv tsim los tiv thaiv kev ua paug lossis kev sib cuag tsis zoo.
-
Ua raws li cov qauv (piv txwv li, iec, ieee) rau cov khoom siv voltage high.
-
-
Kev ua yog:
-
High-precision detsam / capacitors nrog cov kub tsawg / voltage coefficients.
-
Tsawg tsawg ntawm Parasitic Capital Capacitance / Inductance rau cov ntawv thov siab.
-
-
Lub Zog Tuav Tes:
-
Kev tsim nyog yuav tsum muaj cov cua sov zoo; Yuav siv ceramic, roj puv, lossis xaim hluav taws xob.
-
-
Cov lus teb hloov pauv:
-
Tseem ceeb rau pulsed lossis ceev ceev-nce voltages (piv txwv li, xob laim ntsuas). Yuav tsum muaj cov khoom siv tsis tshua muaj thiab thaiv.
-
Cov Ntawv Thov
-
Qho ntsuas:
-
High-voltage probes rau multimeters / oscilloscopes (piv txwv li, 1000: 1 attenuation).
-
Peev hluavtaws hluav taws xob hloov chaw (cvts) hauv cov hwj huam sib luag rau kev ntsuas / tiv thaiv.
