Tus Killer ntawm Photovoltaic Fais Fab Cog-DC Arc

Vim tias qhov yuav tsum tau muaj cov pa roj carbon monoxide thiab cov pa roj carbon peaking, lub zog tshiab kev lag luam yog tam sim no nrov tshwj xeeb.Txhua tus tau pom zoo nrog cov chaw nres tsheb photovoltaic, thiab ntau thiab ntau tus neeg tau nkag mus rau hauv kev lag luam photovoltaic.Txawm li cas los xij, theem ntawm cov neeg koom nrog hauv kev lag luam no tsis sib xws, thiab ntau tus neeg tsis mloog DC arcs, uas ua rau muaj ntau yam xwm txheej.

Arc yog ib yam ntawm cov pa paug tshwm sim.Lub txim hluav taws xob tam sim no tsim los ntawm tam sim no dhau los ntawm qee qhov nruab nrab insulating, xws li huab cua, hu ua arc.Ob qho tib si ncaj qha tam sim no thiab alternating tam sim no tsim arcs.Qee lub sij hawm thaum peb ntsaws rau hauv lub qhov (socket), peb yuav pom cov nplaim taws, uas yog AC arc.Nyob rau hauv DC system, xws li arc tshwm sim los ntawm cov xov tooj ntawm tes photovoltaic hu ua DC arc.Nyob rau hauv sib piv, DC systems muaj feem yuav tsim arcs tshaj AC systems, thiab ib zaug ib tug arc tshwm sim, nws yog nyuaj rau tua lub arc.

Nyob rau hauv lub chaw nres tsheb fais fab photovoltaic, lub photovoltaic panels emit DC hluav taws xob, uas hloov mus rau hauv AC hluav taws xob tsuas yog tom qab dhau los ntawm photovoltaic inverter.Qhov voltages ntawm PV panels yog siab heev, xws li los ntawm ob peb puas volts mus rau qhov siab tshaj plaws ntawm 1500 V. Qhov tseeb, ob peb kaum ntawm volts yog txaus los tsim ib tug DC arc, uas muaj peev xwm tsim tau kub txog li 4200 degrees.Thaum plaub lub tshuab hluav taws xob photovoltaic txuas ua ke, qhov hluav taws xob dav dav yuav ncav cuag li 120 volts.Kev sib txuas zoo thiab tsis zoo ntawm cov xov hlau tam sim ntawd tsim ib qho DC arc, thiab hauv ob peb feeb xwb, qhov kub siab tso cai rau cov tooj liab DC cable kom yaj ncaj qha thiab tig mus rau hauv cov tooj liab poob rau hauv av.Lub melting point ntawm tooj liab yog 1083 degrees, molten tooj liab yog dripping rau ntau lub ru tsev ntoo ntawm lub villa lub txim yog unimaginable, feem ntau yuav ua rau hluav taws, ib co ntawm cov European villa hluav taws yog vim lub ru tsev ntawm photovoltaic fais fab nroj tsuag DC arc tshwm sim. .Yog li ntawd, DC arc tiv thaiv ntawm photovoltaic fais fab nroj tsuag yog ib qho tseem ceeb heev.

Yog li, vim li cas lub chaw tsim hluav taws xob photovoltaic tsim DC arc?Lub ntsiab yog vim li cas rau qhov tshwm sim ntawm DC arc yog: lub davhlau ya nyob twg los yog lub fuse kev twb kev txuas yog tsis compressed, lub busbar ntsia liaj qhov rooj tsis nruj nreem, qhov kev twb kev txuas yog oxidized, lub rwb thaiv tsev hlau yog txo, cov khoom siv rwb thaiv tsev tsis zoo, thiab hais txog.

Dab tsi yog qhov phom sij ntawm DC arc rau photovoltaic fais fab nroj tsuag?Thawj yog kev puas tsuaj rau cov khoom siv.Combiner thawv, DC txee, roj teeb vaj huam sib luag Cheebtsam, connectors, hlws ris thawv, thiab lwm yam yog hlawv tawm.Qhov thib ob yog lub zog poob.Ib qho kev ua tsis tiav yuav ua rau tsawg lossis tsis muaj hluav taws xob.Qhov thib peb yog kev nyab xeeb.Hluav taws kub tuaj yeem ua rau muaj kev nyab xeeb ntawm tus kheej thiab khoom ntiag tug.

Yuav ua li cas yog qhov tshwm sim ntawm hluav taws xob arc tsim nyob rau hauv PV chaw nres tsheb fais fab?Piv txwv li, piv txwv li 10MW fais fab chaw nres tsheb, muaj txog 80,000 junction box connectors thiab 4,000 davhlau ya nyob twg blocks, ntxiv rau lub internal weld pob qij txha ntawm lub roj teeb panels, lub DC txee thiab cov nodes ntawm lub inverter, tag nrho cov ntxiv mus rau yam tsawg kawg yog 84,000, yog li ntawd. Yog tias qhov tshwm sim tsis ua haujlwm yog 1 ntawm 10,000, muaj 8 ntawm lawv, yog li qhov tshwm sim tshwm sim yog siab heev.

Yuav ua li cas kom tsis txhob DC Arc nyob rau hauv Photovoltaic Power Station?

Ua ntej, nco ntsoov siv cov khoom tsis tu ncua thiab tsim nyog, tsis yog cov khoom cuav thiab cov khoom tsis zoo.Zoo li Slocable'smc4 inline fuse connectorthiabsplit hlws ris box.
Qhov thib ob, tus naj npawb ntawm cov nodes yuav tsum raug txo kom ntau li ntau tau.
Thib peb, cov neeg ua haujlwm tsim kho yuav tsum siv cov cuab yeej tshaj lij thiab yuav tsum tau txais kev cob qhia thiab tsim nyog los ntawm kev cob qhia ua haujlwm thiab kev xeem ua ntej lawv raug tso rau hauv txoj haujlwm.
Plaub, tom qab lub chaw nres tsheb fais fab raug teeb tsa, kev tshuaj xyuas cuam tshuam yuav tsum tau ua.
Thib tsib, yuav tsum muaj cov cuab yeej tshawb nrhiav tau sib xws, xws li DC arc nrhiav pom sensor, lawv yuav ceeb toom thiab txiav tawm lub voj voog thaum lawv ntes DC arc kom tshem tawm cov kev phom sij zais.
Thib rau, yuav tsum muaj lub zog saib xyuas lub platform los saib xyuas tag nrho cov ntaub ntawv ua haujlwm hauv lub sijhawm tiag tiag, yog li ntawd thaum pom muaj kev phom sij zais, cov neeg ua haujlwm tuaj yeem raug ceeb toom tam sim los daws lawv.

Qhov tseeb, DC arc tsis txaus ntshai.Tsuav koj paub txoj hauv kev kom raug thiab siv cov tshuaj tiv thaiv kev tshawb fawb, koj tuaj yeem tiv thaiv tau zoo thiab nrog nws.Ib yam li AC fais fab hauv tsev, kev nyab xeeb yog lav tag nrho.Los ntawm cov txheej txheem tseem ceeb, qhov teeb meem ntawm DC arc tiv thaiv thiab tswj tau tuaj yeem daws tau ntawm tus nqi qis.
