Qhov loj dua qhov capacitance ntawm cov khoom kuaj thiab cov xau reactance ntawm qhov ntsuas transformer, qhov pom tseeb dua qhov capacitance nce nyhuv.Yog li ntawd, thaum peb nqa tawm AC tiv thaiv voltage xeem ntawm series resonance loj-muaj peev xwm kuaj cov khoom, nws yuav tsum tau ncaj qha ntsuas qhov voltage ntawm qhov kawg ntawm cov khoom xeem los tiv thaiv cov khoom xeem los ntawm overvoltage voltage.
HV Hipot GDTF-800kVA / 400kV AC Resonant Test System
Lub overvoltage tshwm sim ntawm series resonance xeem ntaus ntawv yog tshwm sim los ntawm cov nram qab no yam:
(1) Thawj winding yog dheev pressurized es tsis txhob maj nce los ntawm xoom voltage.
(2) Thaum tseem muaj qhov hluav taws xob siab dua, dheev txiav tawm lub hwj huam mov, tsis txhob sib npaug rau xoom thiab txiav tawm qhov hluav taws xob.Nws tuaj yeem pom los ntawm cov txheej txheem kev hloov pauv ntawm lub transformer winding uas saum toj no ob qhov xwm txheej yuav ua rau overvoltage ntawm cov khoom kuaj, uas tsis tso cai.
Rau (1) thaiv los ntawm kev tswj Circuit Court los tiv thaiv qhov tsis-zero voltage los ntawm dheev pressurized.
Rau (2) txoj kev ua haujlwm kom raug yuav tsum tau ua nruj me ntsis kom tsis txhob muaj.
(3) Cov ntawv xeem tau tawg sai sai.Qhov no feem ntau ntsib thiab inevitable.Yog tias qhov hluav taws xob kawg ntawm qhov ntsuas transformer yog txuas ncaj qha rau cov khoom kuaj, thaum cov khoom kuaj tau tawg sai sai, lub peev xwm ntawm qhov hluav taws xob qhov hluav taws xob kawg ntawm qhov ntsuas transformer tam sim ntawd raug yuam kom xoom, uas yog sib npaug rau qhov kev txiav txim tam sim ntawd ntawm qhov hluav taws xob. Qhov kawg ntawm qhov kev sim transformer-ib nthwv dej pem hauv ntej yog qhov siab heev Lub ncov tus nqi ntawm lub impulse voltage nthwv dej yog sib npaug rau tus nqi tam sim no ntawm qhov ntsuas tam sim no ntawm cov khoom ntsuas, tab sis qhov polarity yog qhov sib txawv.Qhov no yuav ua rau muaj kev txaus ntshai overvoltages ntawm qhov ntev ntawm cov rwb thaiv tsev ntawm qhov ntsuas transformer windings.
Txoj hauv kev los tiv thaiv nws yog txhawm rau txuas tus tiv thaiv tiv thaiv nrog tus nqi tsim nyog nyob rau hauv cov kab nruab nrab ntawm lub qhov hluav taws xob hloov hluav taws xob kawg ntawm lub zog zaus series resonance kuaj cov cuab yeej thiab cov khoom ntsuas, kom cov impulse voltage ntawm opposite polarity ua nyob rau hauv series Circuit Court. tus tiv thaiv resistor thiab transformer inlet capacitance.Rau ib lub sij hawm luv luv, feem ntau ntawm cov hluav taws xob poob rau ntawm kev tiv thaiv resistor.
