Uas Tseem Ceeb ntawm Capacitor Failure

1.Electrical Overstress

Overvoltage

Cov capacitors yog tsim los nrog lub ntsuas hluav taws xob, thiab siv qhov ntsuas hluav taws xob ntau tshaj qhov ntsuas no tuaj yeem ua rau cov khoom siv hluav taws xob hauv lub capacitor tawg, ua rau luv luv lossis xau. Sustained raug rau overvoltage kuj accelerates kev laus ntawm lub capacitor.

Overcurrent

Tshaj tam sim no tuaj yeem ua rau lub dielectric hauv lub capacitor degrade vim overheating. Qhov cua sov no tsis tsuas yog ua kom cov laus ntawm cov khoom siv dielectric tab sis kuj tuaj yeem deform lossis tawg lub capacitor lub encapsulation.

2. Thermal Stress

Kub kub

Thaum lub capacitor ua haujlwm nyob rau hauv qhov chaw kub kub, nws cov ntaub ntawv sab hauv muaj hnub nyoog sai dua. Piv txwv li, electrolytes tuaj yeem evaporate lossis decompose ntawm qhov kub thiab txias, ua rau txo qis hauv capacitance thiab txawm tias tsis ua haujlwm.

Kub Cycling

Kev hloov pauv kub tsis tu ncua ua rau lub capacitor nthuav dav thiab kev cog lus, uas ua rau muaj kev ntxhov siab ntawm cov khoom siv sab hauv, ua rau poob lossis tawg kev sib txuas.

3. Mechanical Stress

Kev vibration thiab poob siab

Capacitors tuaj yeem muaj kev vibration lossis poob siab thaum siv, uas tuaj yeem ua rau kev sib txuas sab hauv tawg lossis xoob. Qhov no yog tshwj xeeb tshaj yog muaj nyob rau hauv automotive electronics thiab industrial cov khoom.

Lub cev puas tsuaj

Thaum lub sij hawm installation thiab ua hauj lwm, capacitors yuav raug kev puas tsuaj rau lub cev, xws li crushing los yog deformation. Xws li kev puas tsuaj tuaj yeem cuam tshuam rau lub capacitor kev ua haujlwm lossis ua rau tsis ua haujlwm.

4. Tshuaj Stress

Electrolyte Leakage

In electrolytic capacitor, cov electrolyte tuaj yeem xau, ua rau poob qis hauv kev ua haujlwm lossis ua tsis tiav. Electrolyte leakage feem ntau yog vim tsis zoo sealing los yog laus los ntawm kev siv mus ntev.

Tshuaj Corrosion

Lub capacitor lub casing los yog leads yuav corroded los ntawm cov tshuaj nyob rau hauv ib puag ncig, ua rau tsis zoo kev sib cuag los yog luv luv circuits. Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv cov av ntub lossis corrosive gas ib puag ncig.

5. Kev laus

Kev laus ntawm cov khoom siv

Cov ntaub ntawv dielectric nyob rau hauv capacitors degrade nyob rau lub sij hawm, ua rau txo capacitance los yog nce dielectric poob. Piv txwv li, dielectric zaj duab xis hauv zaj duab xis capacitors tuaj yeem ua nkig dhau sijhawm.

Electrolyte Evaporation

Hauv electrolytic capacitors, cov electrolyte maj mam evaporates lub sijhawm, txo cov capacitance. Qhov tshwm sim no tau tshaj tawm nyob rau hauv qhov chaw kub kub. 

6. Kev tsim khoom tsis raug

Kev puas tsuaj hauv cov txheej txheem ntau lawm

Capacitors tej zaum yuav muaj qhov tsis xws luag los ntawm cov txheej txheem tsim khoom, xws li cov teeb meem me me hauv cov yeeb yaj kiab dielectric lossis tsis zoo soldering. Cov teeb meem no tuaj yeem ua rau tsis ua haujlwm thaum siv.
