Vim li cas thiaj ua qis voltage hloov pauv qhov yuav tsum tau them capacitance?
Dec 30, 2020
Hauv qhov hluav taws xob tsis tshua muaj hluav taws xob faib tawm, muaj cov khoom xa hluav taws xob, cov khoom hluav taws xob sab nraud, thiab tau kawg ntawm cov khoom siv hluav taws xob. Dab tsi yog lub luag haujlwm ntawm lub capacitor raug foob? Raws li lub npe pom zoo, nws ua lub luag haujlwm hauv cov nyiaj them cov nqi them capacitor. Cia wb mus saib ntawm lub hauv paus ntsiab lus ntawm lub peev xwm them nyiaj. Thaum kev them nyiaj, lub capacitor thiab cov load tau sib txuas ua ke. Lub capacitor yog tib yam li lub txhab nyiaj hluav taws xob. Thaum lub thauj khoom nce, qhov tso tawm qhov hluav taws xob ntawm lub zog hluav taws xob yuav poob vim tias muaj peev xwm sab hauv ntawm qhov fais fab mov. Qhov ob xaus ntawm tus capacitor yuav tsum tswj cov qub hluav taws xob, uas yog Ib feem ntawm hluav taws xob hauv lub capacitor yuav ntws tawm, ncua qhov qis ntawm qhov poob ntawm qhov hluav taws xob, uas yog lub hauv paus ntsiab lus ntawm capacitor them.
1. Lub ntsiab cai them nqi ntawm cov tswj fais fab
Hauv paus ntsiab lus, tus ntsuas hluav taws xob yog sib npaug rau lub tshuab hluav taws xob uas ua kom muaj lub zog rov qab ua haujlwm. Lub hauv paus ntsiab lus ntawm cov nyiaj them rov qab lub zog yog los txuas cov cuab yeej nrog lub zog ua haujlwm nrog lub zog sib npaug thiab lub zog sib ntxiv nyob rau hauv parallel ntawm tib lub capacitor, thiab lub zog tau hloov ntawm ob lub nra. Nyob rau hauv txoj kev no, lub load ntawm cov hloov pauv thiab kis kab hauv kab sib chaws yog txo qis, yog li ua kom cov zis muaj nuj nqi ntau. Nyob rau hauv cov ntaub ntawv ntawm outputting ib tug tej yam hwj huam nquag, poob ntawm lub hwj huam mov system yog txo. Hauv kev sib piv, cov twj siv tau yog qhov yooj yim tshaj plaws thiab kev lag luam zoo tshaj plaws los txo cov load ntawm transformers, kev siv hluav taws xob, thiab cov faib khoom lag luam. Yog li ntawd, nws yog qhov yuav tsum tau siv cov capacitors ua kev hloov kho lub zog hauv cov hluav taws xob. Tam sim no, nws yog qhov nquag siv shunt capacitors li reactive fais fab nyiaj pab
2. Cov yam ntxwv ntawm lub zog tso nrog them
qhov zoo dua
Lub hwj chim hluav taws xob tiv thaiv cov hluav taws xob cov cuab yeej them nqi hluav taws xob tau yooj yim rau nruab, yooj yim nce lossis tsawg dua rau qhov chaw nruab; qis zog hluav taws xob poob (tsuas yog kwv yees 0.4% ntawm cov peev txheej ntsuas); lub sij hawm tsim kho luv luv; kev nqis peev me; tsis muaj kev sib hloov yam, ua haujlwm yooj yim thiab txij nkawm; ib tug neeg cov peev txheej hauv lub tuam txhab nyiaj puas, Tsis muaj kev cuam tshuam rau kev ua haujlwm ntawm lub txhab nyiaj tag nrho thiab lwm yam zoo.
Nyias tsis zoo
Qhov tsis zoo ntawm lub hwj chim hluav taws xob muaj hluav taws xob tiv thaiv hluav taws xob tiv thaiv cov khoom siv hluav taws xob yog: nws tsuas tuaj yeem hloov kho hauv qib, thiab tsis tuaj yeem hloov kho kom zoo; lub tshuab ua pa tsis zoo, thaum lub kaw lus capacitor ua haujlwm kub dua 70 ℃, nws nquag nthuav dav thiab tawg; cov yam ntxwv tsis zoo rau hluav taws xob, tsis zoo rau luv luv-kev ruaj ntseg, Muaj cov teeb meem tom qab tshem tawm; qhov tseeb ntawm cov hluav taws xob reactive tsawg, uas yog yooj yim rau cuam tshuam rau cov txiaj ntsig nyiaj them rov qab; kev ua haujlwm thiab kev tswj hwm ntawm tus neeg ua kom them nyiaj yog qhov nyuaj thiab qhov teeb meem ntawm kev ua haujlwm nyab xeeb ntawm tus capacitor tsis raug coj los ua tiag.
