Dab tsi yog Qhov Zoo ntawm PV Firefighter Safety Switches?

   PV firefighter kev nyab xeeb hloovyog ib qho tshiab hnub ci vaj huam sib luag kaw kev daws teeb meem tau tshaj txhua txoj hlua inverter.Tam sim no, lub ru tsev faib photovoltaics tau siv dav hauv Tuam Tshoj, Tebchaws Asmeskas, Australia, Europe thiab Nyiv.Yuav ua li cas kom muaj kev nyab xeeb ntawm tus kheej, yuav ua li cas tiv thaiv hluav taws kev pheej hmoo ntawm cov chaw photovoltaic, thiab yuav ua li cas kom ntseeg tau tias cov neeg tsis muaj peev xwm txheeb xyuas thiab txiav cov kev pheej hmoo ntawm thawj zaug tau dhau los ua kev txhawj xeeb hauv txhua lub teb chaws.Slocable yog nyob rau hauv pem hauv ntej ntawm cov thev naus laus zis tsim tshwj xeeb rau kev lag luam hluav taws xob tauj dua tshiab, tshwj xeeb tshaj yog lub hnub ci zog, ua tau raws li cov kev xav tau ntawm kev nyab xeeb thiab siv tau zoo DC hloov, ua tau raws li cov qauv kev lag luam siab tshaj plaws.

Rau cov tshuab hluav taws xob photovoltaic, muaj ob qhov kev pheej hmoo kev nyab xeeb: "DC siab voltage" thiab "kev pheej hmoo cawm".Hauv cov kab ke ib txwm muaj, tag nrho qhov hluav taws xob ntawm tag nrho cov kab hluav taws xob tuaj yeem ncav cuag 600V ~ 1000V.Vim yog qhov xoob ntawm cov khoom sib txuas photovoltaic, kev sib cuag tsis zoo, cov xov hlau tsis zoo, thiab cov rwb thaiv tsev tawg, nws yooj yim ua rau DC arcing, uas yuav ua rau hluav taws kub.Tsis tas li ntawd, thaum muaj hluav taws kub nyhiab tshwm sim vim yog arc rub los yog sab nraud ua rau, nyob rau hauv rooj plaub ntawm DC sab, tam sim no yog generated tsuav yog muaj ib lub teeb tivthaiv.High voltage yog ib txwm muaj.Kev tua hluav taws yog qhov txaus ntshai heev thiab cov neeg tua hluav taws tsis muaj peev xwm cawm tau qhov chaw thiab tsuas yog tswj tau hluav taws los ntawm qhov deb.

Slocable tau pib DC rho tawm hloov pauv thiab PV hluav taws tua hluav taws kev nyab xeeb hloov raws li kev lag luam xav tau.Hauv feem ntau PV systems,DC disconnect keyboardstau muab tso rau hauv DC / AC fais fab inverter, thiab lawv lub hom phiaj tseem ceeb yog txiav tawm lub inverter DC thaum lub sij hawm tu, tab sis nws tsis tuaj yeem ua dab tsi txog DC (600 ~ 1500V) los ntawm lub ru tsev mus rau ntu inverter.Cov kab hluav taws xob nruab nrab ntawm DC hnub ci modules thiab DC / AC fais fab inverters tseem raug mus txog 1000 VDC thaum ua haujlwm hauv lub tsev tom qab DC disconnect hloov mus.Thaum muaj hluav taws kub, cov neeg tua hluav taws tuaj yeem ua rau muaj kev phom sij loj heev.

Lub Slocable firefighter kev nyab xeeb hloov muab kev daws teeb meem uas cov neeg tua hluav taws tua hluav taws xob txuas hluav taws xob AC ua ntej tso hluav taws kom lawv tuaj yeem pib tua hluav taws yam tsis muaj kev pheej hmoo ntawm hluav taws xob.Qhov hluav taws kub kev nyab xeeb hloov pom daim phiaj tsis ua haujlwm thiab cia li kaw qhov kev hloov pauv hloov tom qab 5 vib nas this, tsim kom muaj kev nyab xeeb rau cov neeg tua hluav taws.(AC fais fab tuag = DC fais fab tuag txiav; tsis siv neeg rov pib dua thaum AC fais fab rov qab = DC fais fab rov qab) PV fireman txoj kev nyab xeeb hloov qhov system tuaj yeem ua tau sai, tag nrho thiab remotely disconnected los ntawm PV installation nrog ib tug yooj yim kev txiav txim ntawm lub tswj vaj huam sib luag interface, thiab tseem tuaj yeem ua remotely actuated hla lub xov tooj ntawm tes network.Los ntawm kev tshem tawm PV kev teeb tsa, tsis muaj DC lub zog ua los ntawm PV array, thiab lub zog hluav taws xob DC los ntawm PV modules yuav raug cais tag nrho, uas muaj kev nyab xeeb rau cov neeg tua hluav taws tua hluav taws thiab nkag mus rau hauv lub tsev.

1. Ntau yam khoom lag luam kom tau raws li qhov yuav tsum tau ua ntawm ntau yam kev ua haujlwm
2. Haum rau 600V / 1000V / 1500V photovoltaic system
3. Qhov dav thiab loj dua tam sim no: mus txog 40A
4. Dav AC voltage ntau 100 ~ 270V AC
5. Lub cev muaj zog tsav hloov kev txiav tawm
6. LED qhov taw qhia, ON lossis OFF tuaj yeem txheeb xyuas qhov xwm txheej yooj yim
7. IP65 qib, haum rau sab nraum zoov installation
8. Kov tawm |cable txuas |MC4 connector / 1m AC cable yeem, yooj yim rau cov neeg siv khoom
9. Nruab nrog ua pa valve kom tsis txhob conden-sation nyob rau hauv lub enclosure
10. Built-in kub sensor, tsis siv neeg kaw thaum tshaj 80 ° C
11. Tsis tshua muaj suab nrov thaum ua haujlwm, tsis cuam tshuam rau tib neeg lub neej ib txwm muaj
12. Modular tsim ntawm cov khoom siv, kev saib xyuas sai thiab yooj yim tom qab muag

Nrog rau kev ua tau zoo heev, lub sijhawm xa khoom sai thiab pab pawg tshaj lij tom qab muag tau sai sai rau cov neeg siv khoom xav tau, Slocable's firefighter kev nyab xeeb hloov pauv tau muag zoo hauv European lag luam thiab txuas ntxiv tau txais txiaj ntsig zoo los ntawm cov neeg siv khoom.

Txawm hais tias peb muaj cov kab ntau lawm rau kev tsim khoom loj thiab ua tiav ntau yam ntawm cov qauv kev daws teeb meem, peb cov neeg siv khoom kuj muaj cov kev xav tau tshwj xeeb, thiab peb yuav ua haujlwm nrog cov neeg siv khoom los tsim cov kev daws teeb meem zoo tshaj plaws rau lawv cov kev xav tau.

Cov kev xav tau tshwj xeeb ntawm cov neeg siv khoom yuav txawv nrog cov khoom sib dhos tshwj xeeb ntawm cov khoom uas twb muaj lawm, tab sis kuj tseem tuaj yeem koom nrog kev tsim cov pob tshwj xeeb lossis cov txheej txheem.Slocable muaj peev xwm muab cov neeg siv khoom nrog kev pabcuam zoo heev, peb muaj pab pawg engineers, tsim qauv thiab cov kws tshaj lij.

NEC2017 xav kom PV kev teeb tsa ntawm txhua lub tsev kom muaj peev xwm ua tiav qhov module-qib kaw sai sai thaum muaj xwm txheej ceev.NEC 2017 690.12 kuj tseem muaj cov cai nruj rau kev kaw nrawm nrawm.Qhov kev ncua deb li ntawm 305 hli los ntawm photovoltaic array yog ciam teb.Nyob rau hauv 30s tom qab lub ceev tig-tawm ntaus ntawv yog pib, lub array voltage sab nraum tus ciam teb poob qis dua 30V, thiab qhov voltage nyob rau hauv ciam teb poob qis dua 80V, uas yog, lub vaj huam sib luag-theem kaw yog yuav tsum tau.Qhov kev xav tau no tau pib siv rau lub Ib Hlis 1, 2019.

Tom qab txhim kho PV hluav taws xob hluav taws xob kev nyab xeeb hloov, txhua qhov photovoltaic module tuaj yeem muab faib kom tsis txhob muaj kev phom sij ntawm qhov hluav taws xob siab.Nyob rau hauv cov ntaub ntawv ntawm hluav taws kub, qhov tso zis voltage ntawm lub module yuav raug txiav tawm nyob rau hauv thawj lub sij hawm los xyuas kom meej kev ruaj ntseg ntawm cov hluav taws.

Yuav Ua Li Cas Xaiv Txoj Cai Firefighter Safety Switch Model:

1. Paub meej tias qhov voltage thiab tam sim no xav tau los ntawm lub tshuab photovoltaic
2. Interface yuav tsum: Knockouts |kab mob sib kis |MC4 connector yeem
3. 1 meter AC cable yuav tsum tau los yog tsis
4. 1 ~ 5 txoj hlua muaj
