Kodi Ubwino wa PV Firefighter Safety Switches ndi chiyani?

   PV firefighter chitetezo switchndi njira yatsopano yotsekera ya solar panel yogwirizana ndi ma inverters onse azingwe.Pakalipano, ma photovoltais omwe amagawidwa padenga akhala akugwiritsidwa ntchito kwambiri ku China, United States, Australia, Europe ndi Japan.Momwe mungawonetsere chitetezo chaumwini, momwe mungapewere kuopsa kwa moto wa malo opangira photovoltaic, komanso momwe mungawonetsere kuti anthu omwe si akatswiri amazindikira ndikudula zoopsa pa nthawi yoyamba zakhala zodetsa nkhawa m'mayiko onse.Slocable ili patsogolo pa matekinoloje opangidwa makamaka pamsika wamagetsi ongowonjezwdwa, makamaka mphamvu ya dzuwa, kukwaniritsa zosowa zakusintha kwa DC kotetezeka komanso koyenera, kukwaniritsa miyezo yapamwamba kwambiri yaukadaulo ndi malonda.

Kwa machitidwe a photovoltaic, pali ngozi ziwiri zotetezera: "DC high voltage risk" ndi "rescue risk".M'dongosolo lachikhalidwe, voteji yonse ya mzere wonsewo imatha kufika 600V ~ 1000V.Chifukwa cha kukhudzana kotayirira kwa zolumikizira za photovoltaic, kukhudzana kosauka, mawaya onyowa, ndi kuphulika kwa insulation, ndizosavuta kuyambitsa DC arcing, zomwe zingayambitse moto.Kuonjezera apo, pamene ngozi yamoto imachitika chifukwa cha kukoka kwa arc kapena zifukwa zakunja, pankhani ya mbali ya DC, zamakono zimapangidwira malinga ngati pali gawo lowala.Mphamvu yapamwamba imakhalapo nthawi zonse.Kuzimitsa moto ndikoopsa kwambiri ndipo ozimitsa moto sangathe kupulumutsa malowa ndipo amatha kuwongolera motowo patali.

Slocable yakhazikitsa ma switch a DC isolator ndi masiwichi achitetezo a PV ozimitsa moto malinga ndi kufunikira kwa msika.Mu machitidwe ambiri a PV,DC yodula masiwichiamaphatikizidwa mu inverter yamagetsi ya DC / AC, ndipo cholinga chawo chachikulu ndikudula inverter DC panthawi yokonza, koma sichingachite chilichonse chokhudza DC (600 ~ 1500V) kuchokera padenga kupita ku gawo la inverter.Zingwe zomwe zili pakati pa ma module a solar a DC ndi ma inverters amagetsi a DC / AC akadali pansi mpaka 1000 VDC pomwe akugwira ntchito mkati mwa nyumbayo pambuyo pozimitsa chosinthira cha DC.Pakachitika moto, ozimitsa moto amatha kukumana ndi zoopsa zomwe zingachitike.

Slocable firefighter switch switch imapereka yankho pomwe ozimitsa moto amachotsa gawo lamagetsi a AC asanazimitse moto kuti ayambe kulimbana ndi moto popanda chiopsezo cha electrocution.Chosinthira chitetezo chamoto chimazindikira kulephera kwa gridi ndikuzimitsa chosinthira chopatula pambuyo pa masekondi a 5, ndikupanga malo otetezeka kwa ozimitsa moto.(Kuzimitsa magetsi kwa AC = Kuzimitsa kwa DC zokha; kukonzanso zokha pamene mphamvu ya AC yabwezeretsedwa = DC mphamvu yobwezeretsa) Njira yosinthira chitetezo ya PV yozimitsa moto imatha kulumikizidwa mwachangu, kwathunthu komanso kutali ndi kuyika kwa PV ndikuchita kosavuta pamawonekedwe owongolera, ndipo imatha kulumikizidwa patali ndi netiweki yamafoni.Pochotsa makina a PV, palibe mphamvu ya DC yomwe imayendetsedwa kuchokera ku PV array, ndipo mphamvu yapamwamba ya DC yochokera ku ma modules a PV idzakhala yokhayokha, yomwe imapereka malo otetezeka kwa ozimitsa moto kuti azimitsa moto ndikulowa m'nyumba.

Ubwino wa Slocable PV Firefighter Safety Switch/Rapid Shutdown Switch:

1. Zogulitsa zosiyanasiyana kuti zikwaniritse zofunikira zamitundu yosiyanasiyana yogwirira ntchito
2. Yoyenera 600V/1000V/1500V photovoltaic system
3. Kukula ndi kukulirapo kwapano: mpaka 40A
4. Wider AC voteji osiyanasiyana 100 ~ 270V AC
5. Njinga zoyendetsedwa lophimba kusagwirizana
6. Chizindikiro cha LED, ON kapena OFF chikhoza kuzindikira mosavuta chikhalidwe
7. IP65 kalasi, yoyenera kuyika panja
8. Kugogoda |cholumikizira chingwe |Cholumikizira cha MC4 / 1m AC chingwe chosankha, chosavuta kuyika kwamakasitomala
9. Okonzeka ndi valavu kupuma kupewa conden-sation mkati mpanda
10. Sensa yomangidwa mkati, yozimitsa yokha ikapitilira 80°C
11. Phokoso lochepa panthawi ya ntchito, silimakhudza moyo wamba wa anthu
12. Mapangidwe amtundu wamagulu azinthu, kukonza mwachangu komanso kosavuta pambuyo pogulitsa

Ndi ntchito yabwino kwambiri, nthawi yobweretsera mofulumira komanso gulu la akatswiri pambuyo pogulitsa malonda kuti ayankhe mwamsanga zosowa za makasitomala, Slocable's firefighter switches amagulitsa bwino pamsika wa ku Ulaya ndikupitirizabe kulandiridwa bwino ndi makasitomala.

Ngakhale tili ndi mizere yopangira makina opangira zinthu zambiri komanso mayankho athunthu, makasitomala athu amakhalanso ndi zosowa zapadera, ndipo tidzagwira ntchito ndi makasitomalawa kuti tipeze yankho labwino kwambiri pazosowa zawo.

Zofuna zamakasitomala zitha kusiyanasiyana malinga ndi kuphatikiza kwazinthu zomwe zilipo kale, koma zitha kuphatikizanso kupanga makono kapena makina apadera.Slocable imatha kupatsa makasitomala ntchito zambiri, tili ndi gulu la mainjiniya, opanga ndi akatswiri.

NEC2017 imafuna makhazikitsidwe a PV panyumba zonse kuti athe kukwaniritsa mwachangu kutsekeka kwa ma module pakagwa mwadzidzidzi.NEC 2017 690.12 ilinso ndi zofunika kwambiri zosinthira mwachangu.Mtunda mkati mwa 305mm kuchokera ku photovoltaic array ndi malire.Mkati mwa 30s chipangizo chozimitsa msanga chikayambika, mphamvu yamagetsi kunja kwa malire imatsika pansi pa 30V, ndipo voteji mkati mwa malire amatsika pansi pa 80V, ndiko kuti, kutsekedwa kwa mlingo kumafunika.Izi zidayamba kugwira ntchito pa Januware 1, 2019.

Pambuyo kukhazikitsa PV firefighter chitetezo chosinthira, gawo lililonse la photovoltaic likhoza kugawidwa kuti lisawonongeke kuopsa kwa magetsi apamwamba.Pakakhala moto, mphamvu yotulutsa module imatha kudulidwa nthawi yoyamba kuti zitsimikizire chitetezo cha ozimitsa moto.

Momwe Mungasankhire Mtundu Woyenera Kuwotcha Moto Wozimitsa Moto:

1. Tsimikizani voteji ndi zamakono zomwe zimafunidwa ndi photovoltaic system
2. Zofunikira za mawonekedwe: Knockouts |Zingwe za chingwe |Cholumikizira cha MC4 chosasankha
3. 1 mita AC chingwe chofunika kapena ayi
4. 1 ~ 5 zingwe zilipo
