Thaum lub sij hawm thauj khoom ntawm lub tshuab hluav taws xob, cov rwb thaiv tsev yuav maj mam deteriorate nyob rau hauv qhov kev txiav txim ntawm hluav taws xob teb, kub thiab mechanical vibration rau lub sij hawm ntev, nrog rau tag nrho cov deterioration thiab ib feem ntawm deterioration, ua rau tsis xws luag.Kev ntsuas hluav taws xob tiv thaiv hluav taws xob yog ib txoj hauv kev zoo thiab ncaj qha los txheeb xyuas lub zog hluav taws xob ntawm lub tshuab hluav taws xob, thiab nws yog cov ntsiab lus tseem ceeb ntawm kev ntsuas kev tiv thaiv.Yog li ntawd, Hipot xeem kuj yog ib qho tseem ceeb txhais tau tias kom muaj kev ruaj ntseg ntawm lub tshuab hluav taws xob.
HV Hipot GDVLF Series 0.1Hz Programmable Ultra-tsawg zaus (VLF) High Voltage Generator
Txoj kev ua haujlwm ntawm ultra-tsawg zaus tiv taus qhov ntsuas hluav taws xob rau lub tshuab hluav taws xob zoo ib yam li cov txheej txheem ua haujlwm rau cov cable saum toj no.Cov hauv qab no yog cov lus piav qhia ntxiv ntawm qhov chaw sib txawv ..
1. Qhov kev ntsuam xyuas no tuaj yeem ua tiav thaum lub sijhawm xa khoom, kho dua tshiab, hloov ib nrab ntawm cov windings thiab cov kev xeem niaj hnub.Kev ntsuas qhov ntsuas hluav taws xob ntawm lub cev muaj zog nrog 0.1Hz ultra-tsawg zaus yog qhov ua tau zoo dua rau qhov tsis xws luag ntawm lub tshuab hluav taws xob qhov kawg tshaj qhov hluav taws xob zaus tiv thaiv qhov ntsuas hluav taws xob.Nyob rau hauv lub hwj chim zaus voltage, txij li thaum lub capacitive tam sim no ntws los ntawm cov hlau pas nrig ua rau ib tug loj voltage poob thaum nws ntws los ntawm lub semiconductor anti-corona txheej sab nraum lub rwb thaiv tsev, qhov voltage ntawm rwb thaiv tsev ntawm cov hlau pas nrig kawg yog txo;Nyob rau hauv cov ntaub ntawv ntawm ultra-tsawg zaus, lub capacitor tam sim no yog heev txo, thiab qhov voltage poob ntawm lub semiconductor anti-corona txheej kuj zoo heev txo, yog li qhov voltage ntawm qhov kawg rwb thaiv tsev yog siab dua, uas yog ib qho yooj yim mus nrhiav tau qhov tsis xws luag. cov
2. Txoj kev sib txuas: Qhov kev ntsuam xyuas yuav tsum tau ua nyob rau hauv cov theem, qhov kev sim theem yog pressurized, thiab cov theem tsis kuaj yog luv luv-circuited rau hauv av.
3. Raws li cov kev cai ntawm cov kev cai uas cuam tshuam, lub ncov tus nqi ntawm qhov ntsuas hluav taws xob tuaj yeem txiav txim siab raws li cov qauv hauv qab no:
Umax = √2βKUo Hauv cov qauv, Umax: yog tus nqi siab tshaj ntawm 0.1Hz test voltage (kV) K: feem ntau siv 1.3 txog 1.5, feem ntau siv 1.5
Uo: tus nqi ntsuas ntawm lub tshuab hluav taws xob stator winding Voltage (kV)
β: Sib npaug coefficient ntawm 0.1Hz thiab 50Hz voltage, raws li qhov yuav tsum tau ntawm peb lub teb chaws txoj cai, coj 1.2
Piv txwv li: rau lub tshuab hluav taws xob nrog qhov ntsuas hluav taws xob ntawm 13.8kV, txoj kev suav ntawm qhov ntsuas hluav taws xob siab tshaj tus nqi ntawm ultra-low zaus yog: Umax = √2 × 1.2 × 1.5 × 13.8≈35.1 (kV)
4. Lub sijhawm xeem yog ua raws li cov kev cai cuam tshuam
5. Nyob rau hauv cov txheej txheem ntawm kev tiv thaiv hluav taws xob, yog tias tsis muaj qhov txawv txav, tsis hnov tsw, pa taws thiab cov ntaub ntawv tsis ruaj khov, nws tuaj yeem suav hais tias cov rwb thaiv tsev tau tiv thaiv qhov kev sim ntawm qhov kev sim.Txhawm rau kom nkag siab zoo dua qhov xwm txheej ntawm rwb thaiv tsev, qhov saum npoo ntawm lub rwb thaiv tsev yuav tsum tau saib xyuas kom meej raws li qhov ua tau, tshwj xeeb tshaj yog rau cov cua txias.Kev paub dhau los tau taw qhia tias kev saib xyuas tuaj yeem pom qhov txawv txav ntawm lub tshuab hluav taws xob rwb thaiv tsev uas tsis tuaj yeem cuam tshuam los ntawm cov cuab yeej, xws li nto corona, tso tawm, thiab lwm yam.
