Reactive zog them nyiaj ntsig txog cov ntsiab lus
Feb 10, 2026| 1.Basic txoj cai ntawm reactive fais fab nyiaj them
Lub hauv paus ntsiab lus tseem ceeb suav nrog kev sib txuas cov cuab yeej nrog lub zog hluav taws xob hauv qhov sib npaug nrog lub zog inductive hauv tib lub voj voog. Thaum lub capacitive load tso tawm lub zog, lub inductive load absorbs nws; conversely, thaum lub inductive load tso tawm lub zog, lub capacitive load absorbs nws. Qhov kev sib pauv ntawm lub zog ntawm ob hom kev thauj khoom tso cai rau lub zog reactive absorbed los ntawm inductive load yuav tsum tau them los ntawm reactive zog tso zis los ntawm lub capacitive load. Qhov no yog lub hauv paus ntsiab lus ntawm reactive zog them nyiaj.
2. Lub hwj chim yam raug nplua
Qhov no yog hais txog tus nqi ntxiv rau cov neeg siv hluav taws xob raws li feem pua ntawm lawv cov nqi hluav taws xob thaum lub zog siv hluav taws xob ntawm lawv cov khoom siv hluav taws xob ntau dhau, ua rau lub zog hluav taws xob poob qis dua lub teb chaws cov qauv.
3. Inrush tam sim no thiab overvoltage
Inrush tam sim no yog tam sim no tam sim no generated thaum lub capacitor hloov. Piv txwv li, thaum lub contactor hloov ntawm lub capacitor yam tsis tau hla qhov xoom-voltage point, lub capacitor coj zoo li lub voj voog luv luv thaum lub sijhawm hloov, ua rau muaj qhov tam sim no uas tuaj yeem yog kaum lossis ntau pua zaus ntau dua li lub capacitor qhov ntsuas tam sim no. Qhov no tuaj yeem cuam tshuam ntau cov ntsiab lus tsis muaj zog hauv lub capacitor lub dielectric txheej, ua rau lub capacitor tsis tuaj yeem khaws lub zog thiab ua rau nws lub neej ua haujlwm luv. Yog li ntawd, contactor-raws li lub tsev txhab nyiaj capacitor yuav tsum tsis txhob hloov ntau zaus.
Overvoltage yog qhov voltage instantaneous generated thaum lub capacitor raug kaw. Thaum lub capacitor raug rho tawm, daim phiaj voltage thiab lub capacitor lub davhlau ya nyob twg voltage superimpose, ua rau overvoltage.
4. Hloov oscillation
Hloov oscillation tshwm sim thaum hloov ntawm lub capacitor ua rau overcompensation, thaum hloov nws tawm ua rau undercompensation, ua rau lub capacitor hloov thiab tawm ntau zaus thiab tsim oscillations.
5. Overcompensation thiab undercompensation
Undercompensation yog hais txog qhov xwm txheej hauv lub zog siv hluav taws xob uas lub zog inductive reactive tshaj li lub zog reactive zog.
Overcompensation yog hais txog qhov xwm txheej hauv lub zog siv hluav taws xob uas lub zog muaj zog reactive tshaj inductive reactive zog.
6. Kev puas tsuaj ntawm kev xa rov qab reactive zog
Rov qab reactive fais fab kis tau tus mob, zoo li undercompensation, ua rau ib theem sib txawv ntawm voltage thiab tam sim no, uas ua rau ib tug heev tsawg zog yam tseem ceeb.
