Electrolytic Capacitor Explosion: Ib Hom Hluav Taws Xob
Thaum lub electrolytic capacitor tawg, nws lub hwj chim yuav tsum tsis txhob underestimated. Ntawm no yog cov feem ntau ua rau lub capacitor tawg, yog li ceev faj thaum sib dhos!
1. Rov qab polarity
- Rau cov polarized capacitors zoo li bullhorn capacitors, txuas qhov zoo thiab qhov tsis zoo terminals nyob rau hauv rov qab tuaj yeem ua rau lub capacitor kub hnyiab tawm hauv cov mob me me, lossis ua rau muaj kev tawg nyob rau hauv cov xwm txheej hnyav dua.
2. Bulging
- Thaum ib nrab tso tawm, dielectric tawg, thiab hnyav ionization tshwm sim hauv lubcapacitor, lub overvoltage txo qhov pib ionization voltage hauv qab lub zog hluav taws xob ua haujlwm. Qhov no ua rau muaj kev cuam tshuam ntawm lub cev, tshuaj lom neeg, thiab hluav taws xob, ua kom cov rwb thaiv tsev tsis zoo, tsim cov pa roj, thiab tsim kom muaj lub voj voog tsis zoo. Qhov nce hauv siab ua rau lub plhaub capacitor tuaj yeem ua rau tawg thiab tuaj yeem tawg.
3.Kev puas tsuaj rwb thaiv tsev ntawm lub plhaub
- High-voltage sab ntawm ibelectrolytic capacitor's leads yog ua los ntawm nyias steel los xij. Yog tias kev tsim khoom tsis zoo - xws li cov npoo tsis sib xws, burrs, lossis khoov ntse - cov ntsiab lus ntse tuaj yeem ua rau ib nrab tawm. Qhov kev tso tawm no tuaj yeem rhuav tshem cov roj, ua rau lub casing nthuav dav, thiab txo cov roj theem, ua rau lub rwb thaiv tsev tsis ua haujlwm. Tsis tas li ntawd, yog tias lub kaum sab xis welds overheated thaum lub sij hawm sealing, nws tuaj yeem ua rau cov rwb thaiv tsev puas, ua cov roj stains thiab roj, txo qis voltage thiab ua rau tsis ua haujlwm.
4.Capacitor tawg tshwm sim los ntawm kev them nyiaj thaum nyob
- Cov tsev txhab nyiaj capacitor ntawm txhua qhov ntsuas hluav taws xob yuav tsum tsis txhob rov txuas mus rau lub voj voog nyob. Txhua lub sij hawm ib lub txhab nyiaj capacitor reconnected, nws yuav tsum tau muab tso tawm tag nrho tsawg kawg yog 3 feeb nrog rau qhov qhib qhib. Txwv tsis pub, qhov polarity ntawm qhov tam sim no voltage thaum kaw yuav rov qab mus rau qhov seem seem ntawm lub capacitor, ua rau tawg.
5. Kub kub ua rau lub Capacitor tawg
- Yog hais tias qhov kub ntawm lub electrolytic capacitor siab dhau lawm, cov electrolyte sab hauv yuav vaporize sai thiab nthuav, nws thiaj li tawg lub plhaub thiab ua rau tawg. Cov laj thawj rau qhov no yog:
- Ntau dhau voltage ua rau kev puas tsuaj thiab nce sai ntawm cov dej ntws los ntawm lub capacitor.
- Ambient kub tshaj lub capacitor qhov tso cai ua haujlwm kub, ua rau cov electrolyte boil.
- Rov qab polarity kev twb kev txuas.
Tam sim no koj nkag siab qhov ua rau ntawm electrolytic capacitor tawg, nws yog ib qho tseem ceeb los hais txog cov hauv paus ntsiab lus kom tsis txhob muaj qhov ua tsis tiav. Kev khaws cia kom zoo kuj tseem ceeb. Yog tias cov capacitors raug tshav ntuj ncaj qha, qhov sib txawv ntawm qhov kub thiab txias, corrosive gases, kub kub, lossis av noo, kev ua haujlwm ntawm kev ruaj ntseg capacitors yuav degrade. Yog tias lub capacitor kev nyab xeeb tau khaws cia rau ntau tshaj ib xyoos, nco ntsoov xyuas nws cov kev ua tau zoo ua ntej siv.
