Kev sib sib zog nqus dej | Yuav ua li cas YMIN lub anti-vibration capacitors daws cov kev sib tw vibration ntawm low-altitude ya tsheb hluav taws xob tswj tshuab?

Taw qhia

Tsawg-altitude ya tsheb hluav taws xob tswj tshuab feem ntau ua tsis tiav vim muaj kev vibration siab thaum lub sijhawm ya davhlau, ua rau muaj qhov txawv txav ntawm qhov system teb, degraded filtering kev ua tau zoo, thiab txawm tias davhlau ya nyob twg. Traditional capacitors muaj kev co tsis txaus (5-10g), ua rau lawv tsis tuaj yeem ua tau raws li qhov yuav tsum tau muaj kev ntseeg siab hauv qhov chaw huab cua.

YMIN's Solution

Nrog rau qhov tshwm sim ntawm SiC cov khoom siv thiab nce kev hloov pauv ntau zaus, cov khoom siv hluav taws xob hauv OBC modules yuav tsum tiv taus ntau dua ripple tam sim no thiab thermal stresses. Ordinary txhuas electrolytic capacitor yog nquag overheating thiab muaj lub neej luv luv. Ua kom muaj peev xwm ua tau zoo, siab tiv taus hluav taws xob, qis ESR, thiab lub neej ntev hauv pob khoom tau dhau los ua qhov mob tseem ceeb hauv OBC tsim.

- Root Cause Technical Analysis -

Nyob rau hauv ib qho kev vibrating ib puag ncig, cov qauv sab hauv ntawm lub capacitor yog qhov ua rau qaug zog, ua rau electrolyte to, solder joint cracking, capacitance drift, thiab nce ESR. Cov teeb meem no ntxiv dag zog rau lub suab nrov thiab voltage ripple, cuam tshuam rau kev ua haujlwm zoo ntawm cov khoom tseem ceeb xws li MCU thiab sensors.

- YMIN Solutions thiab Txheej Txheem Zoo -

YMIN cov kua-hom, tiv thaiv kev vibration baseplate nti txhuas electrolytic capacitors txhim khu kev ntseeg tau los ntawm cov qauv hauv qab no:

Ua kom muaj zog tiv thaiv kev vibration: Lub hauv paus muaj zog thiab cov khoom siv sab hauv zoo muab kev poob siab ntawm 10-30g;

Ua kua electrolyte system: Muab cov hluav taws xob ruaj khov thiab ua kom sov;

High ripple kuj thiab tsis tshua muaj to tam sim no: Haum rau high-frequency switching power supply scenarios, txhim kho system efficiency.

Kev ntseeg tau cov ntaub ntawv pov thawj & xaiv cov lus pom zoo

Kev ntsuam xyuas qhia tau hais tias tom qab 500 teev ntawm kev ua haujlwm hauv 30g kev co ib puag ncig, lub capacitor hloov pauv tus nqi qis dua 5%, thiab nws ESR tseem nyob ruaj khov. Lub kaw lus teb qeeb thaum lub sij hawm kuaj vibration yog txo qis, thiab kev tswj kev ya davhlau raug txhim kho, tshwj xeeb tshaj yog nyob rau hauv huab cua tsis zoo.

Kev khiav hauj lwm kub: -55 ° C rau + 125 ° C (Capacitance degradation tsawg dua -10% ntawm -40 ° C, kom ruaj khov zog cia thiab lim kev ua haujlwm).

Lifespan: 2000 teev

Vibration Resistance: 30G

Impedance: ≤0.25Ω @ 100kHz

Ripple Tam sim no: Mus txog 400mA @ 100kHz hauv qab 125 ° C siab ntsuas kub

- Daim ntawv thov Scenario thiab cov qauv pom zoo -

Dav siv nyob rau hauv low-altitude ya tsheb hluav taws xob tswj, OBC capacitor kev daws teeb meem, thiab kev tswj fais fab hauv tsheb.

Cov qauv pom zoo:VKL (T) 50V, 220μF, 10 * 10-20% - + 20%, Coated Aluminium Housing, 2K, Vibration-Resistant Seat Phaj, CG

Cov qauv no tau siv rau hauv kev siv tiag tiag.
