Koj tau nqis peev hauv lub hnub ci vaj huam sib luag, optimizers, thiab lub zog inverter. Koj tab tom saib lub ntsuas hluav taws xob tig rov qab, zoo siab txog cov kilowatts huv. Tab sis muaj ib qho me me, qhov tseem ceeb ua haujlwm tom qab qhov xwm txheej uas tsim nyog lub suab nrov: DC Fuse.
Xav txog koj lub hnub ci array ua ib qho kev sib txuas ntawm cov dej muaj zog. Lub hnub ci yog qhov chaw, cov kab hluav taws xob yog cov dej ntws, thiab koj lub inverter yog qhov chaw ua haujlwm. Tam sim no, xav txog qhov tam sim ntawd, kev puas tsuaj loj los yog muaj kev kub ntxhov - luv luv los yog ua txhaum. Yog tias tsis muaj kev tswj hwm kev tso tawm, lub zog ntawd tsis muaj qhov mus rau qhov twg tab sis tsim kev puas tsuaj, overheating cables, thiab txawm tias hluav taws.
Qhov no yog qhov uas tus txo hwj chim DC fuse dhau los ua tus superhero.
DC Fuse Ua li cas hauv cov ntsiab lus yooj yim?
Nws yog ib qho kev sib txuas tsis muaj zog. Nws txoj hauj lwm ib leeg yog ua tsis tau zoo. Thaum qhov hluav taws xob ua txhaum cai ua rau tam sim no ua rau muaj kev phom sij tshaj qhov tsim ntawm lub cev, cov hlau me me hauv lub fuses sai sai thiab yaj. Qhov kev txiav txim no rhuav tshem lub voj voog, nres qhov txawv txav tam sim no, thiab cais cov seem faulty.
Vim li cas DC Fuse tshwj xeeb yog qhov tseem ceeb hauv hnub ci?
"Lub DC phom sij": Tsis zoo li AC sab ntawm koj lub inverter, DC sab ntawm koj cov vaj huam sib luag muaj qhov tsis tu ncua, siab -voltage tam sim no. Tsis muaj qhov "zero crossing" taw tes los pab tua qhov arc. DC hluav taws xob txhaum cai tuaj yeem ua rau muaj kev phom sij, hluav taws kub hnyiab tau ntev dua. Lub fuse yog tsim los tua qhov arc sai sai thiab txiav txim siab.
Kev tiv thaiv nyob rau hauv Ob qho kev taw qhia: Koj cov vaj huam sib luag tsim hluav taws xob, tab sis qhov txhaum kuj tuaj yeem xa rov qab mus rau hauv txoj hlua puas. Fuses tiv thaiv modules los ntawm qhov rov qab tam sim no los ntawm kev tsis sib xws lossis kev ua tsis tiav nyob rau lwm qhov hauv cov array.
Cov teeb meem cais tawm: Hauv lub kaw lus loj nrog ntau txoj hlua, qhov txhaum hauv ib txoj hlua yuav tsum tsis txhob muab koj lub hnub ci tag nrho. Txoj hlua fuses cais ib txoj hlua uas muaj teeb meem, tso cai rau tus so kom tsim lub zog thaum koj hais qhov teeb meem.
Cov cuab yeej tiv thaiv: Nws yog thawj kab ntawm kev tiv thaiv rau koj lub inverter muaj txiaj ntsig. Los ntawm kev tso tseg qhov txhaum ntawm cov kab DC, nws tiv thaiv kev puas tsuaj rau cov khoom siv hluav taws xob hauv inverter.
Koj yuav nrhiav tau lawv qhov twg?
Feem ntau nyob rau hauv DC combiner lub thawv (qhov twg ntau lub vaj huam sib luag cov hlua tuaj ua ke), thiab qee zaum yog ib feem tseem ceeb ntawm inverter's DC input seem.
Kab hauv qab:
Lub DC fuse yog ib qho khoom siv tsis muaj -negotiable. Nws yog ib qho kev nqis peev me me rau kev nyab xeeb, kev ntseeg siab, thiab kev tiv thaiv khoom vaj khoom tsev. Nws ua haujlwm ntsiag to, tsis pom, thiab koj vam tias koj yuav tsis xav tau. Tab sis yog tias muaj ib qho txhaum tshwm sim, koj yuav zoo siab heev uas nws nyob ntawd, sawv zov.
