Ndezvipi Zvakanakira zvePV Firefighter Safety switchches?

   PV firefighter kuchengetedza switchndeye inogadziridza solar panel shutdown solution inoenderana neese akajairwa tambo inverters.Parizvino, photovoltaics yakagoverwa padenga yakashandiswa zvakanyanya muChina, United States, Australia, Europe neJapan.Nzira yekuve nechokwadi chekuchengetedzwa kwemunhu, nzira yekudzivirira njodzi yemoto yezvivakwa zve photovoltaic, uye maitiro ekuona kuti vasiri nyanzvi vanoziva uye kubvisa njodzi panguva yekutanga dzave kunetseka kwakajairika munyika dzese.Slocable iri kumberi kwematekinoroji akagadziridzwa zvakanangana nemusika wesimba rinodzokororwa, kunyanya simba rezuva, rinosangana nezvinodiwa zvekuchengetedza uye zvinobudirira DC switching, kusangana nepamusoro pehunyanzvi uye kutengeserana zviyero.

Kune ma photovoltaic systems, kune ngozi mbiri dzekuchengetedza: "DC high voltage risk" uye "recue risk".Mune yechinyakare nhevedzano system, iyo yakazara voltage yeiyo yese mutsara mutsara inogona kusvika 600V ~ 1000V.Nekuda kwekusangana kwakasununguka kweiyo photovoltaic connectors, kusabatana kwakashata, waya dzakanyorova, uye kuputika kwekudzivirira, zviri nyore kukonzera DC arcing, izvo zvinogona kukonzera moto.Mukuwedzera, kana njodzi yemoto ikaitika nekuda kwekudhonza kwearc kana zvikonzero zvekunze, munyaya yeDC side, ikozvino inogadzirwa chero bedzi pane chiedza chechiedza.High voltage inogara iripo.Kudzima moto kune ngozi zvikuru uye vanodzima moto havakwanisi kununura nzvimbo uye vanogona chete kudzora moto uri kure.

Slocable yatanga DC isolator switch uye PV firefighter kuchengetedza switch zvinoenderana nekudiwa kwemusika.Mune akawanda PV masisitimu,DC bvisa ma switchdzakabatanidzwa muDC / AC magetsi inverter, uye chinangwa chavo chikuru ndechekucheka inverter DC panguva yekugadzirisa, asi haigoni kuita chero chinhu pamusoro peDC (600 ~ 1500V) kubva padenga kusvika kune chikamu che inverter.Tambo dziri pakati peDC solar modules uye DC/AC magetsi inverters dzichiri pasi pe1000 VDC ichiri kushanda mukati mechivako mushure mekunge DC yakadzimwa switch.Muchiitiko chemoto, vanodzima moto vanogona kutarisana nenjodzi dzakakomba zvikuru.

Iyo Slocable firefighter kuchengetedza switch inopa mhinduro apo vanodzima moto vanobvisa iyo AC simba redunhu vasati vadzima moto kuti vatange kurwisa moto pasina njodzi yemagetsi.Iyo yekudzivirira moto switch inoona kutadza kwegridi uye inodzima otomatiki switch ye isolator mushure memasekondi mashanu, ichigadzira nzvimbo yakachengeteka yevanodzima moto.(AC simba rinodzima = DC simba rinodzima otomatiki; reset otomatiki kana AC simba radzoreredzwa = DC simba kudzoreredza) Iyo PV fireman's kuchengetedza switch system inogona kukurumidza, zvachose uye kure kure kubva pakuisirwa kwePV nechiito chiri nyore pane control panel interface, uye inogona kutoshandiswa kure kure nenharembozha network.Nekubvisa iyo PV kuiswa, hapana simba reDC rinoitwa kubva kuPV array, uye iyo yakakwirira-voltage DC simba kubva kuPV modules ichave yakasarudzika, iyo inopa yakachengeteka mamiriro evanodzima moto kudzima moto uye kupinda muchivako.

Zvakanakira zveSlocable PV Firefighter Chengetedza Shandura/Kurumidza Shutdown Switch:

1. Zvigadzirwa zvakasiyana-siyana zvekusangana nezvinodiwa zvemamiriro akasiyana-siyana ekushanda
2. Inokodzera 600V/1000V/1500V photovoltaic system
3. Yakafara uye yakakura ikozvino: kusvika ku40A
4. Yakafara AC voltage range 100 ~ 270V AC
5. Motor inofambiswa chinja disconnection
6. Chiratidzo che LED, ON kana OFF inogona kuziva mamiriro acho nyore
7. IP65 giredhi, yakanyatsokodzera kuiswa kwekunze
8. Knock outs |cable connector |MC4 yekubatanidza / 1m AC tambo sarudzo, yakanakira kuisirwa mutengi
9. Yakashongedzerwa nevharuvhu yekufema kudzivirira conden-sation mukati meiyo yakavharirwa
10. Yakavakwa-mukati tembiricha sensor, otomatiki kudzimwa kana kupfuura 80°C
11. Mutsindo wakaderera panguva yekushanda, haukanganisi hupenyu hwevanhu
12. Modular dhizaini yezvigadzirwa zvechigadzirwa, nekukurumidza uye nyore mushure mekutengesa-kugadzirisa

Nekuita kwakanakisa, nguva yekukurumidza kuendesa uye nyanzvi mushure mekutengesa timu kuti ikurumidze kupindura kune zvinodiwa nevatengi, Slocable's firefighter security switches inotengesa zvakanaka mumusika weEurope uye inoramba ichigamuchirwa zvakanaka nevatengi.

Kunyangwe isu tiine otomatiki mitsara yekugadzira yekugadzirwa kwakawanda uye huwandu hwakazara hwemhinduro dzakajairwa, vatengi vedu vanewo zvakakosha zvakajairwa zvinodiwa, uye isu tichashanda nevatengi ava kugadzira mhinduro yakanakisa yezvavanoda.

Zvido zvemutengi zvinogona kusiyana nekusangana kwakananga kwezvinhu zviripo, asi zvinogona kusanganisira kugadzirwa kwemapfundo kana michina.Slocable inokwanisa kupa vatengi basa rakazara kwazvo, isu tine timu yeinjiniya, vagadziri uye matekiniki.

NEC2017 inoda kuiswa kwePV pazvivakwa zvese kuti ikwanise kukurumidza kuwana module-level shutdown mumamiriro enjodzi.NEC 2017 690.12 zvakare ine zvakaomesesa zvinodiwa zvekukurumidza kudzima switch.Iyo kureba mukati me305mm kubva kune photovoltaic array ndiyo muganhu.Mukati me30s mushure mekukurumidza kudzima mudziyo watanga, iyo array voltage kunze kwemuganhu inodonha pazasi 30V, uye voltage mukati memuganhu inodonha pasi pe80V, ndiko kuti, kuvharika kwepanel-level kunodiwa.Ichi chinodiwa chakatanga kushanda muna Ndira 1, 2019.

Mushure mekuisa iyo PV firefighter kuchengetedza switch, yega yega photovoltaic module inogona kukamurwa kudzivirira njodzi yekukwira voltage.Kana moto, iyo inobuda voltage yemodule inogona kugurwa panguva yekutanga kuve nechokwadi chekuchengetedzwa kwevanodzima moto.

Maitiro Ekusarudza Iyo Yakakodzera Firefighter Chengetedza Switch Model:

1. Simbisa iyo voltage uye ikozvino inodiwa ne photovoltaic system
2. Interface zvinodiwa: Knockouts |Cable glands |MC4 connector ingasarudze
3. 1 mita AC tambo inodiwa kana kwete
4. 1 ~ 5 tambo dziripo
