Kev sib txuas: Hluav taws xob & hluav taws xob sib npaug ntawm cov tshuab

Walmart qhov kev iab liam tias qee qhov hluav taws kub hauv cov nroj tsuag hnub ci ntawm lub ru tsev ntawm nws cov khw muag khoom tau pib los ntawm cov khoom sib txuas echoes txhawj xeeb txog kev lag luam tau muaj qee lub sijhawm.Thiab cov teeb meem mus deb dhau ib qho chaw tsim khoom lossis tus neeg tsim khoom.

Ntau tus cwj mem tau nchuav dhau qhov kev foob foob los ntawm Walmart tawm tsam Tesla, ntsig txog qhov hluav taws kub ntawm hnub ci kev teeb tsa ntawm lub ru tsev ntawm nws lub khw.Tab sis ob peb tus neeg sau xov xwm tau nug tias vim li cas cov hluav taws kub no tshwm sim thawj zaug, tshwj xeeb tshaj yog nrog cov ntaub ntawv qhia meej meej tias cov hnub ci teeb pom kev zoo tsis pib hluav taws.

Thiab txoj cai muaj thawj qhov tsis paub - tias cov teeb meem yuav tsis nyob hauv cov arrays lawv tus kheej, ntau npaum li lawv tau teeb tsa li cas.Kev tshawb nrhiav sai rau "connector" qhia tau hais tias lo lus no tshwm sim ntau zaus hauv cov lus hu los ntawm Walmart thaum Lub Yim Hli 20, 2019.

Tsis tsuas yog Walmart liam tias qhov hluav taws kub ntawm cov khw muag khoom hauv Milpitas thiab Lakeside, California tau pib los ntawm kev sib txuas tsis raug, tab sis lub tuam txhab kuj tau lees tias Tesla cov neeg ua haujlwm tau sib txuas cov khoom sib txuas uas tsis sib haum xeeb, uas lawv tau ua tsis tiav ntawm cov khoom sib txuas kom txaus, thiab tau ua tsis tau tejyam los hloov faulty connectors los yog kom zoo torque cov nram qab no soj ntsuam, tag nrho cov uas ua rau tsis zoo tej yam kev mob.

Raws li tau tshaj tawm hauv tsab ntawv tshaj tawm tom qab los ntawm Kev Lag Luam Insider, Tesla tau ua haujlwm sab hauv los hloov cov khoom sib txuas, uas tau txheeb xyuas tias yog Amphenol H4 connectors.Amphenol tau tsis kam lees tias nws cov khoom txuas tsis muaj dab tsi cuam tshuam nrog hluav taws, tab sis cov xov xwm tshiab kawg no yog lwm qhov muag dub rau lub tuam txhab tom qab SolarWorld rov qab los ntawm cov qauv siv Amphenol connectors ob thiab ib nrab xyoo dhau los.

Txawm li cas los xij, pv cov ntawv xov xwm tshawb fawb qhia tias cov teeb meem nrog cov khoom sib txuas thiab lawv cov kev teeb tsa yog qhov tob dua li ib qho chaw tsim khoom lossis cov neeg tsim khoom, thiab cov teeb meem nrog cov khoom sib txuas tuaj yeem yog lub foob pob tawg rau lub hnub ci kev lag luam.

"Kuv xav hais tias nws yog ib qho xwm txheej, tab sis nws yog qhov teeb meem loj heev hauv kev lag luam," sau tseg Brian Mills, tus thawj tswj khoom lag luam - photovoltaics rau Stäubli, uas nyob rau hauv lub npe qub ntawm Multi-Contact muab cov khoom sib txuas rau ze li ntawm ib nrab ntawm hnub ci online thoob ntiaj teb.

Stäubli hais txog Kev Ua Haujlwm Tsis Ua Haujlwm thiab Kev Tshawb Fawb Txog Kev Tshawb Fawb (FMEA) los ntawm EU-nyiaj pab rau Hnub Ci Kev Lag Luam Kev Lag Luam, uas txheeb xyuas kev siv ntau hom kev sib txuas - kev coj ua paub hauv kev lag luam "kev sib txuas lus" - raws li deb ntawm qhov ua rau ntawm module tsis ua haujlwm, nrog rau ntau yam kev sib txuas tsis ua haujlwm tau pom tias yog cov teeb meem kim tshaj plaws.

Kom meej meej, qhov no tsis tau txhais hais tias txhua qhov teeb meem connector xaus rau hauv lub ru tsev blazing los yog teb.Tab sis nws qhia tau hais tias cov connectors tau ua qhov teeb meem loj.

Yuav kom nkag siab tias yog vim li cas qhov no yog qhov teeb meem, qee qhov tseeb ntawm cov connectors yuav tsum to taub.Txhua lub chaw tsim khoom sib txuas ua rau lawv cov khoom lag luam rau lawv tus kheej cov qauv sab hauv, thiab thaum cov khoom no feem ntau tau lees paub los ntawm UL lossis lwm lub koom haum, tsis muaj ib qho qauv rau cov khoom sib txuas zoo li muaj rau cov khoom siv hluav taws xob uas nkag mus rau hauv phab ntsa.

Thiab qhov sib txawv tsis yog superficial.Cov khoom sib txuas yog tsim los ntawm ntau cov ntaub ntawv sib txawv, thiab Shoals Technologies CEO Dean Solon sau tseg tias thaum muaj ntau lub high-end connectors muaj tooj liab, qee qhov chaw tsim khoom siv tooj liab lossis txhuas alloys, thiab hais tias nws tau pom txawm tias muaj kev sib cuag hlau.

Tsis tas li ntawd, tsis muaj ib qho qauv rau qhov loj me los yog kam rau ua ntawm cov khoom sib txuas, uas txhais tau hais tias txawm tias ob qho khoom sib txuas los ntawm cov tuam txhab sib txawv zoo li lawv yog tib qhov loj thiab cov duab, qhov sib txawv imperceptible tuaj yeem yog tiag tiag - thiab damning.

Brian Mills ntawm Stäubli hais tias kev sib txuas lus sib txuas yog ua txhaum cai ntawm National Electrical Code (NEC), tab sis hais tias nws tsis tau tso tseg ntau tus installers los ntawm kev ua raws nraim qhov no.

"Peb tau tso tseg cov neeg siv khoom uas xav tau kev sib txuas sib txuas," Shoals CEO Dean Solon hais rau pv magazine."Peb hais rau lawv tias peb tsis xav ua ib feem ntawm kev foob."

Muab hais tias kev sib txuas lus sib txuas ua txhaum NEC thiab cov khoom sib txuas sib txawv los ntawm cov tuam txhab sib txawv tuaj yeem muaj qhov sib txawv tsis pom zoo, koj xav tias cov tuam txhab yuav xav kom meej tias lawv cov khoom tsis tuaj yeem cuam tshuam nrog cov khoom los ntawm cov chaw tsim khoom sib txawv.

Tab sis qhov ntawd yuav tsis hnov ​​​​qab tib neeg tsis muaj zog ntawm avarice, thiab yuav ua li cas qhov no tuaj yeem cuam tshuam rau lub sijhawm ntev.Solon thiab Mills ob qho tib si nco ntsoov tias ntau cov khoom sib txuas tau piav qhia tias "MC-4 tau tshaj" ntawm cov ntawv tsim qauv cov ntaub ntawv, tawm tswv yim rau cov neeg nruab tias lawv tuaj yeem cuam tshuam nrog Stäubli's MC-4.

Thiab txawm hais tias cov lus qhia meej los ntawm Stäubli tias nws qhov kev lees paub yuav raug ua txhaum yog tias nws cov khoom sib txuas tau sib raug zoo nrog cov khoom lag luam los ntawm lwm tus neeg muag khoom, qhov no tsis tau tso tseg "MC-4 tshaj" daim ntawv lo.

Shoals hais tias cov neeg tsim qauv yuav tsum tau hais txog ntawm no, thiab tias thaum nws muab cov pob khoom nrog rau cov khoom siv rau cov neeg siv khoom, nws xav kom cov neeg muag khoom sau tag nrho cov lus qhia tshwj xeeb, suav nrog cov npe ntawm cov chaw tsim khoom uas tsim cov khoom sib txuas uas nyob ntawm cov modules.

Ob leeg Mills thiab Solon nco ntsoov tias qhov teeb meem nrog kev siv cov khoom siv pheej yig thiab / lossis cuam tshuam cov no rau lwm cov khoom sib txuas yog qhov tsis txaus ntseeg, muab qhov txuas me me ntxiv rau tag nrho cov nqi ntawm cov qauv.

"Koj tab tom tham txog 1% ntawm tag nrho cov nyiaj tshuav ntawm cov ntaub ntawv rau cov tuam txhab txuag kom pheej yig," hais tias Dean Solon ntawm Shoals.Nws hais tias vim yog qhov nws tau piav qhia tias yog qhov ua yuam kev ruam, nws pab neeg tam sim no rov ua haujlwm ib puag ncig 800 MW ntawm cov phiaj xwm hnub ci uas tau teeb tsa tsuas yog ob peb xyoos dhau los, suav nrog kev sib pauv hluav taws xob sib npaug ntawm cov kab ke.

Thiab txawm hais tias tsis yog txhua qhov kev sib txuas tsis ua haujlwm ua rau muaj hluav taws, muaj kev phom sij tiag tiag - suav nrog rau cov neeg teeb tsa."Lawv tsis nkag siab tias kev sib cuam tshuam hauv PV system yog cov ntsiab lus txaus ntshai tshaj plaws," hais tawm Mills.

“Lub zog uas muaj nyob rau ntawm lub sijhawm ntawd yog qhov loj heev.Nws yog qhov kev txiav txim siab ntau dua li txhua yam koj yuav ntsib hauv koj lub tsev, nws yog DC kev sib txuas, thiab nws sab nraud. "

Shoals 'Dean Solon sau tseg tias qhov no tseem tuaj yeem ua rau muaj teeb meem kev cai lij choj loj."Thawj zaug ib tus neeg raug hluav taws xob, cov kws lij choj yuav yog cov neeg zoo siab tshaj plaws hauv chav."

Dean Solon, Brian Mills thiab Jan Mastny ntawm LEONi yuav sib tham txog yuav ua li cas kom tsis txhob muaj hluav taws kub, nrog rau cov teeb meem nrog cov khoom sib txuas, ntawm pv magazine's Quality Roundtable ntawm Solar Power International kev lag luam qhia hauv Salt Lake City thaum lub Cuaj Hlis 25. Kev tuaj koom yog pub dawb rau cov neeg uas muaj SPI. hla.Nyem qhov no kom paub ntau ntxiv txog qhov kev tshwm sim no thiab sau npe.

Koj yuav xav tias cov vaj huam sib luag yuav raug xa nrog dub npog kom lawv tsis tuaj yeem electrocute lub installer.

Wow.Kuv xav tias tag nrho cov connectors no yog standardized.Lawv yuav tsum yog.Kuv tau pom tias qhov zoo ntawm cov neeg tsim khoom sib txawv heev.Tab sis tag nrho cov connectors kuv tau pom zoo heev tib yam thiab interconnect.Teeb meem loj nyob ntawd cov neeg.Zoo dua ua ib yam ASAP.
