Vim li cas Capacitors tuaj yeem tawg
Dec 18, 2025| Ⅰ.Ua kom muaj zog Capacitor tawg:
Overvoltage:Lub hwj chim capacitor muaj qhov txwv siab tshaj rau cov ntsuas hluav taws xob. Thaum lub kaw lus voltage siab dhau los yog muaj kev cuam tshuam dhau los ntawm cov hluav taws xob overvoltages (xws li xob laim, hloov pauv, thiab lwm yam), lub zog hluav taws xob sab hauv ntawm lub capacitor tuaj yeem tshaj qhov muaj peev xwm ntawm nws cov khoom siv insulating, ua rau cov rwb thaiv tsev tawg.
Harmonic Influence:Cov capacitors yog cov rhiab heev rau siab - zaus tam sim no (harmonics). Tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj coob tus uas tsis yog - linear loads, harmonic tam sim no nyob rau hauv lub kaw lus yuav ua rau kom muaj cua sov sab hauv thiab ceev rwb thaiv tsev aging nyob rau hauv lub capacitor, uas tej zaum yuav kawg ua rau puas.
Kev laus ntawm Insulating Material:Sab hauv insulating dielectric ntawm lub capacitor maj mam muaj hnub nyoog dhau sijhawm thiab nyob rau hauv kev ua haujlwm (xws li qhov kub thiab txias, qhov hloov pauv ntawm qhov hluav taws xob), ua rau poob qis hauv kev ua haujlwm rwb thaiv tsev. Aged dielectric yog qhov ua rau me me tawm thaum nyob hauv qhov hluav taws xob; Cov txiaj ntsig ntawm cov kev tso tawm no tuaj yeem ua rau dielectric tawg.
Tsis zoo Installation Ib puag ncig:Qhov kub thiab txias, cov av noo siab, lossis cov plua plav ib puag ncig tuaj yeem ua rau lub sijhawm laus ntawm lub capacitor lub rwb thaiv tsev sab hauv thiab tuaj yeem ua rau qee qhov tawm thiab tawg. Piv txwv li, qhov kub thiab txias ntau dhau ua rau lub capacitor ua haujlwm tam sim no, yog li ua kom muaj cua sov ntau ntxiv thiab muaj peev xwm ua rau tawg.
Manufacturing Defects:Yog hais tias muaj cov txheej txheem tsis zoo thaum lub sij hawm tsim khoom ntawm lub capacitor (xws li cov dielectric tsis sib npaug, cov vuam tsis zoo ntawm cov ntawv ci lossis cov hlau lead, thiab lwm yam), lawv tuaj yeem ua rau qee qhov tawm lossis luv luv thaum lub sijhawm ua haujlwm, ua rau tawg.
Overcurrent:Capacitors yog tsim los nrog cov ntsuas tam sim no. Yog tias lub kaw lus tam sim no dhau qhov kev txwv no, ua rau lub capacitor ua haujlwm nyob rau hauv cov xwm txheej overcurrent, hnyav sab hauv yuav tshwm sim. Cov khoom siv insulating, raug rau ntev -lub sij hawm kub thiab siab siab, ua rau muaj kev cuam tshuam ntau dua.
II. Txhawm rau tiv thaiv Capacitor tawg, cov kev ntsuas hauv qab no tau pom zoo:
Siv cov khoom siv tiv thaiv overvoltage tsim nyog.
Txhim kho cov cuab yeej lim dej kom txo qis kev sib haum xeeb.
Xaiv lub siab -zoo, txhim khu kev qha capacitors uas ua tau raws li qhov system qhov voltage thiab tam sim no.
Tsis tu ncua tshuaj xyuas thiab tswj cov capacitors kom ntseeg tau tias lawv ua haujlwm hauv ib puag ncig zoo.
