Lub rwb thaiv tsev tsis kam sim test rau ntsuas cov khoom siv tsis kam ntawm cov khoom siv hluav taws xob, cov khoom siv hluav taws xob ua haujlwm hauv lub xeev thiab tsis txhob muaj cov xwm txheej hluav taws xob xws li hluav taws xob kev raug mob thiab khoom puas tsuaj.
Cov teeb meem nquag ntawm rwb thaiv tsev tsis kam mus kuaj yog li nram no:
1. Thaum ntsuas ntsuas ntsuas hluav taws xob tawm, qhov kev sib raug zoo ntawm cov khoom tawm luv luv ntawm Rwb thaiv tsev thiab cov ntaub ntawv ntsuas, thiab yog vim li cas?
Cov zis luv luv ntawm cov rwb thaiv tsev luv ntawm cov rwb thaiv tsev tsis kam mus kuaj cov neeg ua haujlwm tuaj yeem cuam tshuam txog kev tiv thaiv sab hauv ntawm cov hluav taws xob siab.
Ntau cov khoom ntsuas muaj peev xwm siv tau, xws li cov khoom ntsuas ntev, thaum pib ntawm cov txheej txheem sib tw, thaum pib siv hluav taws xob, qhov kev ntsuas siab nyob rau hauv lub rwb thaiv tsev yuav tsum them Lub capacitor los ntawm nws sab hauv kev tiv thaiv, thiab maj mam them lub voltage rau cov zis ntsuas siab ntsuas ntawm lub rwb thaiv tsev rwb thaiv tsev. Yog tias lub peev xwm muaj txiaj ntsig ntawm cov khoom ntsuas yog qhov loj, lossis sab hauv kev tawm tsam ntawm qhov siab voltage yog loj, txoj kev them nqi yuav siv sijhawm ntev dua.
Nws qhov ntev tuaj yeem txiav txim siab los ntawm cov khoom ntawm r thiab c thauj (hauv vib nas this (hauv vib nas this), piv txwv li t = r = r * r * r * c thauj khoom.
Yog li ntawd, thaum lub sijhawm kuaj, thauj khoom lub peev xwm uas yuav tsum tau them rau qhov ntsuas hluav taws xob, thiab cov twj them ua ke ntawm kev them nqi tam sim no thiab cov ntaub ntawv uas yog DV / DT = I / C.
Yog li ntawd, qhov me dua sab hauv kev tawm tsam yog, qhov loj dua ntawm kev them nyiaj tam sim no yog, thiab nrawm dua li qhov kev ntsuas ntsuas tau yog.
2. Dab tsi yog qhov ua haujlwm ntawm "g" kawg ntawm kev ntsuas? Hauv kev sim ib puag ncig ntawm cov hluav taws xob ntau thiab cov tsis kam, vim li cas qhov ntsuas txuas nrog "g" davhlau ya nyob twg?
Lub "g" kawg ntawm lub twj paj nruag yog kev tiv thaiv davhlau ya nyob twg, uas yog siv los tshem tawm cov cawv ntawm noo noo thiab av hauv qhov chaw xeem ntawm kev ntsuas cov txiaj ntsig. Qhov "g" kawg ntawm lub ntsuas yog los bypass qhov xau tam sim no nyob rau ntawm qhov kev sim tam sim no tsis dhau qhov ntsuas ntawm lub twj paj nruag, tshem tawm qhov yuam kev los ntawm kev xau dej tam sim no. Thaum kuaj cov txiaj ntsig siab tiv taus tus nqi, lub g kawg yuav tsum tau siv.
Feem ntau hais lus, G-Terminal tuaj yeem txiav txim siab thaum nws siab dua 10G. Txawm li cas los xij, qhov no tiv taus ntau yog tsis meej. Nws yog huv thiab qhuav, thiab cov ntim ntawm cov khoom ntsuas yog me me, yog li nws tuaj yeem ruaj khov yam tsis muaj ntsuas 500g ntawm G-xaus; Nyob rau hauv cov chaw ntub dej thiab av ib puag ncig, cov khoom tsis tuaj yeem tseem xav tau G lub davhlau ya nyob twg. Tshwj xeeb, yog tias nws pom tias qhov tshwm sim nyuaj rau kev ruaj khov thaum ntsuas qhov siab tsis kam, lub g-terminal yuav suav tau. Ib qho ntxiv, nws yuav tsum tau sau tseg tias cov shielding terminal g tsis txuas nrog insulator txheej, tab sis txuas nrog cov insulator txheej ntawm l thiab e, lossis hauv ntau cov strand xaim, tsis yog rau lwm cov xov hlau.
3. Vim li cas nws thiaj li tsim nyog los ntsuas tsis tsuas yog cov ntshiab tsis yog, tab sis kuj tseem qhov ntsuas tsis haum thiab polarization index thaum ntsuas cov rwb thaiv tsev?
PI Puas yog qhov ntsuas polarization, uas yog hais txog kev sib piv ntawm rwb thaiv tsev tsis kam hauv 10 feeb thiab 1 feeb thaum lub sijhawm rwb thaiv tsev;
Dar yog lub dielectric kev sib xws, uas yog hais txog kev sib piv ntawm cov rwb thaiv tsev tsis kam nyob rau hauv ib feeb thiab uas nyob rau hauv 15s;
Nyob rau hauv cov rwb thaiv tsev kuaj, lub rwb thaiv tsev rwb thaiv tsev tsis kam lees txog tus nqi tsis tuaj yeem ua rau muaj kev ua haujlwm zoo ntawm kev ntsuas ntawm cov khoom ntsuas. Qhov no yog vim ob qho laj thawj hauv qab no: Ntawm ib sab, lub rwb thaiv tsev rwb thaiv tsev yog me me thaum lub ntim loj, thiab loj thaum lub ntim me me. Ntawm qhov tod tes, tau them tus nqi ua tiav thiab cov txheej txheem polarization hauv insulating cov ntaub ntawv thaum HEEV voltage yog thov. Yog li ntawd, lub zog hluav taws xob yuav tsum tau hais tias qhov kev nqus tau sib xws (R60s rau R1Ming kev ntsuas, cable, tsav thiab ntau lwm lub sijhawm tuaj yeem raug txiav txim los ntawm Cov ntaub ntawv no.
4. Vim li cas thiaj tuaj yeem siv ntau lub roj teeb hluav taws xob rwb thaiv tsev hluav taws xob tsis kam ua cov dc voltage? Qhov no yog raws li txoj ntsiab cai ntawm kev hloov dua siab tshiab. Tom qab kev txhawb nqa hluav taws xob ua tiav, cov khoom siv qis dua hluav taws xob tau tsa mus rau qhov kev tawm suab dua DC voltage. Txawm hais tias qhov tsim hluav taws xob siab yog siab dua, cov zis zog yog qhov me dua (lub zog qis thiab me me tam sim no).
Nco tseg: txawm hais tias lub zog me me heev, nws tsis pom zoo kom kov tau cov kev xeem xeem, tseem yuav muaj kev sojntsuam kev xeem, tseem yuav muaj tingling.
