Lub "Lub Plawv Zoo" ntawm Cov Txheej Txheem Khaws Cia Zog: YMIN Capacitors

Hauv lub caij nyoog tshiab ntawm lub zog, cov txheej txheem khaws cia lub zog yog lub hauv paus tseem ceeb rau kev siv lub zog zoo. YMIN capacitors, nrog lawv cov kev ua tau zoo tshaj plaws, yog cov khoom tseem ceeb rau kev txhim kho kev ruaj khov, kev ua haujlwm zoo, thiab kev ntseeg siab ntawm cov txheej txheem khaws cia lub zog. Cov hauv qab no yog lawv lub luag haujlwm tseem ceeb hauv cov txheej txheem khaws cia lub zog:

1. Lub Chaw Fais Fab ntawm Lub Tshuab Hloov Fais Fab (PCS)

Cov cuab yeej hloov pauv hluav taws xob yuav tsum ua tiav kev hloov pauv hluav taws xob ob txoj kev ntawm cov roj teeb thiab lub grid. Cov capacitors YMIN ua peb lub luag haujlwm tseem ceeb hauv cov txheej txheem no:

• Muaj peev xwm khaws cia hluav taws xob loj: Nws nqus thiab tso tawm hluav taws xob sai sai kom txo qhov kev hloov pauv ntawm lub zog hluav taws xob hauv lub network, ua kom lub kaw lus ua haujlwm tas mus li. Lawv kuj muab kev them rov qab rau lub zog hluav taws xob rau cov khoom siv inductive thiab txhim kho kev ua haujlwm ntawm lub cev muaj zog.

• Kev tiv thaiv hluav taws xob siab heev: Tiv taus cov hluav taws xob siab ntawm 1500V txog 2700V, nqus cov hluav taws xob nce siab, thiab tiv thaiv cov khoom siv fais fab xws li IGBTs thiab SiC ntawm kev puas tsuaj.

• Kev tiv thaiv hluav taws xob siab: Tus qauv tsim ESR qis (mus txog 6mΩ) nqus tau cov hluav taws xob siab ntawm DC-Link, ua kom qhov kev tswj hwm hluav taws xob raug, thiab txhawb nqa kev pib mos kom txo qhov kev poob siab ntawm cov khoom siv.

2. Lub zog tswj hluav taws xob rau Inverters

Hauv cov inverters rau cov chaw siv hluav taws xob rov ua dua tshiab xws li photovoltaic thiab cua zog, YMIN capacitors muab:

• Muaj Peev Xwm Ceev: Khaws cia ntau dua ib lub ntim khoom yuav ua rau kev hloov pauv DC-rau-AC zoo dua.

• Kev Lim Harmonic: Kev kam rau siab ntawm cov hluav taws xob ripple lim tawm cov harmonics tso zis, ua kom lub zog txuas nrog grid zoo.

• Kev Ruaj Ntseg Kub: Qhov kub ua haujlwm dav dav (-40 ° C txog + 125 ° C) ua kom muaj kev ua haujlwm ruaj khov mus sij hawm ntev hauv qhov chaw kub siab.

3. Kev Tiv Thaiv Kev Nyab Xeeb rau Cov Txheej Txheem Tswj Xyuas Roj Teeb (BMS)

Hauv BMSs, YMIN capacitors tiv thaiv kev nyab xeeb ntawm lub roj teeb los ntawm peb txoj hauv kev:

• Kev Sib Npaug Hluav Taws Xob: Txuas nrog cov roj teeb ua ke, lawv yuav kho qhov sib txawv ntawm hluav taws xob ntawm lub xov tooj kom ntev lub neej ntawm lub roj teeb.

• Kev Teb Sai Sai: Lawv lub peev xwm siab tso cai rau kev tso tawm lub zog tam sim ntawd kom ua tau raws li qhov nce ntawm qhov hnyav sai sai thiab tiv thaiv kev tso tawm ntau dhau.

• Kev Tiv Thaiv Qhov Txhaum: Ua haujlwm ua lub zog thaub qab, lawv tswj kev ua haujlwm ntawm lub voj voog tiv thaiv yog tias lub kaw lus ua haujlwm tsis zoo, thiab txiav cov kev sib txuas uas tsis muaj zog sai sai.

4. Cov Supercapacitors: Zoo ib yam li Kev Nyab Xeeb thiab Lub Neej Ntev

Cov modules YMIN supercapacitor muab cov kev xaiv tshiab rau kev nyab xeeb rau cov roj teeb lithium ib txwm muaj:

• Kev Nyab Xeeb Siab: Tsis muaj hluav taws lossis tawg thaum muaj kev sib tsoo, kev sib tsoo, lossis kev luv luv, tau ntawv pov thawj rau kev nyab xeeb ntawm tsheb.

• Siv tau ntev, Tsis tas yuav kho: Lub neej voj voog ntau tshaj 100,000 voj voog, ua rau lub neej ua haujlwm ntev txog ntau xyoo, nrog rau kev siv hluav taws xob zoo li qub tsawg li 1–2μA.

• Kev Hloov Kho Tau Thaum Kub Qis: Kev muab hluav taws xob ruaj khov hauv qhov kub thiab txias heev ntawm -40°C, daws cov teeb meem kaw thaum txias rau cov ntsuas ntse thiab cov khoom siv hauv tsheb.

Xaus lus

Cov YMIN capacitors, nrog lawv cov txiaj ntsig tseem ceeb ntawm kev tiv taus hluav taws xob siab, muaj peev xwm loj, lub neej ntev, thiab kev nyab xeeb tshwj xeeb, tau koom ua ke tob rau hauv cov converters, inverters, BMSs, thiab supercapacitor modules ntawm cov txheej txheem khaws cia hluav taws xob, ua lub hauv paus ntawm kev hloov pauv hluav taws xob zoo thiab kev tswj hwm kev nyab xeeb. Lawv cov thev naus laus zis tsis yog tsuas yog thawb cov txheej txheem khaws cia hluav taws xob mus rau lub sijhawm "tsis tas yuav saib xyuas", tab sis kuj ua kom nrawm dua kev hloov pauv thoob ntiaj teb mus rau qhov qauv hluav taws xob ntsuab, ntse, thiab txhim khu kev qha.
