▍ ANATEL Homologation yog dab tsi?

ANATEL yog luv luv rau Agencia Nacional de Telecomunicacoes uas yog Brazil tsoomfwv txoj cai tswjfwm kev sib txuas lus cov khoom lag luam rau ob qho tib si yuav tsum tau lees paub thiab yeem daim ntawv pov thawj. Nws cov kev pom zoo thiab kev ua raws cai yog tib yam rau Brazil cov khoom siv hauv tsev thiab txawv teb chaws. Yog tias cov khoom muaj feem xyuam rau cov ntawv pov thawj uas yuav tsum tau ua, cov ntawv xeem thiab daim ntawv tshaj tawm yuav tsum ua raws li cov cai thiab cov cai uas tau thov los ntawm ANATEL. Daim ntawv pov thawj khoom yuav tsum tau tso cai los ntawm ANATEL ua ntej cov khoom lag luam nthuav tawm hauv kev lag luam thiab muab tso rau hauv daim ntawv thov.

▍ Leej twg yog tus lav rau ANATEL Homologation?

Lub koom haum Brazilian tsoomfwv tus qauv, lwm lub koom haum lees paub thiab cov chaw kuaj sim yog ANATEL daim ntawv pov thawj txoj cai rau kev tshuaj xyuas cov txheej txheem tsim khoom, xws li cov txheej txheem tsim khoom, kev yuav khoom, txheej txheem tsim khoom, tom qab kev pabcuam thiab lwm yam txhawm rau txheeb xyuas cov khoom siv lub cev kom ua raws. nrog Brazil tus qauv. Tus neeg tsim khoom yuav tsum muab cov ntaub ntawv thiab cov qauv rau kev sim thiab ntsuas.

▍ Vim li cas MCM?

● MCM muaj 10 xyoo kev paub dhau los thiab cov peev txheej hauv kev sim thiab ntawv pov thawj kev lag luam: cov kev pabcuam zoo, pab pawg ua haujlwm tau zoo, ceev thiab yooj yim daim ntawv pov thawj thiab cov kev daws teeb meem.

● MCM koom tes nrog ntau lub koom haum zoo hauv zos uas tau lees paub los muab ntau yam kev daws teeb meem, kev pabcuam raug thiab yooj yim rau cov neeg siv khoom.

Qhov kev taw qhia ntawm "yuav tsum tau ua nyob rau hauv luv luv-circuit test" tau raug kev sib cav ntau dua. Lub hom phiaj yog nyob rau hauv seb lub xeev ntawm lub internal short-circuit yuav simulated kom raug. Cov lus nug uas tau tsa los mas yog raws li nram no: A) Covroj teebrhuav tshem nws qhov chaw electrochemical thaum lub sij hawm disassembly txheej txheem. Txawm hais tias cov txheej txheem disassembly xav kom cov dej lwg qis dua -25 ℃, nws tseem tsis tuaj yeem lav tag nrho tias lub roj teeb tswj nws lub xeev qub. B) Txawm hais tias daim ntawv npib tsib xee tuaj yeem tho lub diaphragm, thiab yog tias nws tsis tho, nws puas tuaj yeem hais tias qhov kev xeem tau tsim nyog. Kauj ruam 7 Installation Nruab lub jip rau nias. Hauv qab ntawm qhov txav ntawm cov khoom siv xovxwm (xws li nias jip) yog ua los ntawm nitrile roj hmab lossis acrylic resin, uas yog muab tso rau ntawm 10x10mm stainless hlau ncej. Lub nitrile roj hmab hauv qab nto yog rau kev sim cylindrical cell. Rau kev sim prismatic cell, 5 × 5 (2mm thickness) acrylic resin yog muab tso rau ntawm nitrile roj hmab. Kauj Ruam 8 Teem cov kev txwv Cov khoom siv tau txav mus los ntawm qhov nrawm ntawm 0.1mm / s. Teem lub caij txiav tawm: quab yuam ntawm cov xovxwm ncav cuag siab txog 400N rau lub prismatic cell thiab 800N rau lub cylindrical cell los yog qhov voltage poob ntau tshaj 50mV. Khaws 30s nyob rau hauv qhov kev txiav tawm. Kauj Ruam 9 Crush Cov qauv raug kuaj thaum qhov kub thiab txias ua tau raws li qhov yuav tsum tau ua. Kauj Ruam 10 Kev Txais Txais Tsis muaj hluav taws kub. Sau cov quab yuam thaum muaj ib qho luv luv-circuit tshwm sim yog tias tsis muaj hluav taws kub.
本期 主 要内 第 12 页C) Puas muaj lwm txoj hauv kev los simulate qhov luv luv ntawm lub roj teeb? Peb yuav tham txog cov teeb meem saum toj no kom meej: Raws li kev sib sau ntawm cov qauv kuaj tau ntau xyoo, cov electrolyte yog tag nrho volatilized thaum lub sij hawm disassembly txheej txheem, cov ncej yog qhuav tag thiab cov khoom txheej ntog li ntawm 5%. Qhov ua tau yog: ib puag ncig ntawm dismantling tsis ua raws li qhov yuav tsum tau ua, thiab lub sijhawm dismantling ntev dhau lawm. Rau cov ntaub ntawv uas cov nickel phaj tsis puncture lub diaphragm, qhov kev ntsuam xyuas nyob rau hauv cov ntaub ntawv no yuav tsum tau suav hais tias ua tsis tiav nyob rau hauv kuv tus kheej to taub. Yog li ntawd, seb tus qauv dhau qhov yuam kev hauv luv luv Circuit Court yuav tsum tau kuaj dua. Yog vim li cas yog lub hom phiaj ntawm qhov kev sim no yog simulate qhov tshwm sim ntawm ib qho luv luv Circuit Court. Yog hais tias lub nickel phaj tsis puncture lub diaphragm, yuav tsis muaj tshwm sim ntawm ib tug luv luv Circuit Court, uas yog, tsis muaj simulation rau qhov tshwm sim ntawm ib tug luv luv Circuit Court. Txoj hauv kev yooj yim los txiav txim siab seb lub diaphragm puas yog pierced yog saib seb puas muaj hluav taws xob poob thaum lub sijhawm kuaj
