Rwb thaiv tsev tiv thaiv yog qhov tsim nyog rau ntsuas cov khoom siv tsis kam ntawm ntau yam thiab cov khoom siv hluav taws xob, cov roj hluav taws xob ua haujlwm kom tsis txhob muaj hluav taws xob, kev raug mob thiab khoom siv Kev puas tsuaj.
Cov teeb meem tshwm sim ntawm rwb thaiv tsev tsis kam mus kuaj yog li nram no:
1. Thaum ntsuas ntsuas thauj khoom tawm tsam, qhov kev sib raug zoo ntawm cov chaw rwb thaiv cov chaw kuaj thiab cov ntaub ntawv ntsuas, thiab yog vim li cas?
Qhov loj me ntawm cov zis luv luv ntawm lub rwb thaiv tsev tam sim no ntawm lub rwb thaiv tsev tsis kam mus kuaj cov neeg ua haujlwm ntawm lub high-voltage hauv lub mgger.
Ntau lub rwb thaiv tsev cov phiaj xwm lub hom phiaj capacitive capacitive capacitive capacitive ceem, xws li cable ntev dua, cov motors nrog cov cua ntau dua, thiab hloov pauv. Yog li ntawd, thaum lub hom phiaj ntsuas tau muaj peev xwm siv tau, qhov pib ntawm cov chaw ntsuas kev ntsuas, thiab maj mam them tus tswv hluav taws xob yuav tsum them tus nqi hluav taws xob yuav tsum them tus nqi hluav taws xob ntxiv rau cov khoom siv ntau ntawm cov Rwb thaiv tsev tsis kam tester. Cov. Yog tias lub peev xwm muaj txiaj ntsig ntawm lub hom phiaj ntsuas yog qhov loj, lossis sab hauv kev tawm tsam ntawm cov hluav taws xob siab loj yog qhov loj, cov txheej txheem them yuav siv sijhawm ntev dua.
Nws qhov ntev tuaj yeem txiav txim siab los ntawm cov khoom ntawm r sab hauv thiab c thauj khoom (chav tsev: Thib ob), uas yog, t = r = r clener * c thauj khoom.
Yog li ntawd, thaum lub sijhawm kuaj, nws yog qhov tsim nyog los them cov peev txheej ntawm kev ntsuas DV / DT yog sib npaug ntawm cov nqi tam sim no kuv mus rau lub laub thauj khoom tam sim no C. Qhov ntawd yog, DV / DT = I / c.
Yog li ntawd, qhov me dua ntawm sab hauv kev tawm tsam thiab ntau dua qhov kev them nyiaj tam sim no, yuav ruaj khov.
2. Dab tsi yog txoj haujlwm ntawm "G" sab ntawm cov tsos? Nyob rau hauv lub high-voltage thiab kev ntsuas siab tiv thaiv ib puag ncig, vim li cas nws thiaj li yuav tsum tau txuas lub "g" lub davhlau ya nyob sab nraud?
Lub "g" kawg ntawm saum npoo yog kev tiv thaiv davhlau ya nyob twg. Txoj haujlwm ntawm kev tiv thaiv kev tiv thaiv yog kom tshem tawm cov cawv ntawm cov av noo thiab av hauv qhov chaw xeem ntawm kev ntsuas cov txiaj ntsig. Sab nraud "G" Terminal BillPasses cov xau dej tam sim no tsis dhau qhov kev sim sab nraud, thiab tias tshem tawm qhov yuam kev ntawm cov dej xau yuam kev los ntawm cov xau dej tam sim no. Lub G Underinal yog siv thaum kuaj cov siab tiv thaiv.
Feem ntau hais lus, Gentinal G tuaj yeem suav tau rau siab dua 10G. Txawm li cas los xij, qhov no tiv taus ntau yog tsis paub meej. Thaum nws huv thiab qhuav thiab ntim ntawm cov khoom xeem yog me me, nws tuaj yeem ruaj tsis tau yam tsis muaj ntsuas 500g ntawm G kawg. Hauv cov chaw qias neeg noo thiab av qias neeg, ib tus nqi qis dua kuj yuav tsum muaj g kawg. Tshwj xeeb, yog tias koj pom tias qhov tshwm sim yog qhov nyuaj rau kev ruaj khov thaum ntsuas ntau dua, koj tuaj yeem txiav txim siab siv lub G Terminal. Tsis tas li ntawd nco ntsoov tias lub shielding terminal g tsis txuas nrog daim thaiv npog txheej, tab sis mus rau insulator ntawm l thiab e lossis rau ntau cov xov hlau ntau, tsis yog rau lwm cov xov hlau tsis sib xws.
3. Vim li cas nws tsis tsuas yog yuav tsum ntsuas cov txiaj ntsig dawb huv thaum ntsuas rwb thaiv tsev, tab sis kuj ntsuas qhov kev nqus piv thiab polarization index. Dab tsi yog qhov kis?
PI Puas yog qhov ntsuas polarization, uas yog hais txog kev sib piv ntawm cov rwb thaiv tsev tsis kam ntawm 10 feeb thaum lub sijhawm kuaj cov rwb thaiv tsev;
Dar yog lub dielectric kev sib piv, uas yog hais txog kev sib piv ntawm cov rwb thaiv tsev tsis kam ntawm 1 feeb thiab lub sijhawm kuaj;
Nyob rau hauv cov rwb thaiv tsev kuaj, lub rwb thaiv tsev tsis kam lees tus nqi ntawm lub sijhawm tsis tuaj yeem xav txog kev ntsuas cov rwb thaiv tsev. Qhov no yog vim yog ob qho laj thawj hauv qab no. Ntawm ib sab tes, lub rwb thaiv tsev tsis kam ntawm tib yam kev ua haujlwm ntawm cov khoom siv rwb thaiv tsev yog qhov loj me me. , Cov rwb thaiv tsev tsis kam tshwm sim thaum lub ntim me me. Ntawm qhov tod tes, cov ntaub ntawv insulating muaj cov txheej txheem ntawm kev nqus piv thiab cov txheej txheem polarization ntawm kev them nyiaj tom qab qhov kev ntsuas siab yog siv. Yog li ntawd, lub zog hluav taws xob yuav tsum ntsuas ntsuas qhov ntsuas ntawm R10min kev ntsuas-Rwb thaiv tsev ntawm Rulation of Rwb thaiv tsev, thiab ntau lwm lub sijhawm, thiab siv qhov no Cov ntaub ntawv los txiav txim cov rwb thaiv tsev zoo los sis phem.
4. Vim li cas thiaj tuaj yeem siv hluav taws xob hluav taws xob tsis kam ua DC siab ntau dua thaum muaj ntau lub roj teeb? Qhov no yog raws li txoj ntsiab cai ntawm kev hloov dua siab tshiab. Lub Zog Hluav Taws Xob Hluav Taws Xob yog tsa mus rau cov zis siab dua DC voltage los ntawm kev txhawb nqa hluav taws xob ua. Lub siab voltage generated yog siab dua tab sis cov zis zog yog me me (lub zog qis thiab me me tam sim no).
Nco tseg: txawm hais tias lub zog me me heev, nws tsis pom zoo rau tus kheej kov cov kev kuaj mob sim, tseem yuav muaj kev sib tw tingling.
