Zomwe Muyenera Kuziganizira Musanagule PV DC Disconnect switch?

Mu kukhazikitsa PV, ndiKusintha kwa DCali ngati airbag m'galimoto.Muyezo wa IEC 60364-7-712 umafunika kugwiritsa ntchito PV DC kulumikiza masiwichi pakati pa gulu la PV ndi inverter.Ma Slocable DC disconnect switches adapangidwa makamaka kuti asalumikize ma inverter a DC/AC kuchokera kumagulu a solar.Timapereka ma switch a PV osalumikiza ma voltages mpaka 1500 V DC.Atha kugwiritsidwa ntchito popanga zosinthira zodziyimira pawokha monga momwe VDE 6012 imafunira, mwachitsanzo, kulola kulumikizidwa kotetezeka kwa ma inverters opanda vuto.Ma switch onse a DC switch cholumikizira pamitengo iwiri ndipo ndi oyenera makina omwe adafukulidwa.

Nyumba ya PV disconnect switch ndi yokonzeka kukhazikitsidwa ndipo imapereka ntchito ya 30 A pa 1000 V/1500 V DC.Zopezeka mu zingwe ziwiri ndi zinayi komanso mitundu iwiri yolumikizira yolumikizira.MC4 kapena ma metric cable glands amalola kusakanikirana kosalala mumalingaliro osiyanasiyana amachitidwe.Chotsekera chotchinga cha DC chili ndi gulu lachitetezo cha IP66 ndipo ndichoyenera kuyika panja.Ntchito yotseka imapereka chitetezo panthawi yautumiki ndi kukonza.The pressure compensation element imalepheretsa condensation kusonkhanitsidwa motero imalepheretsa kulephera chifukwa cha mphezi.

Zomwe Ziyenera Kuganiziridwa Musanagule Kusintha kwa PV Disconnect?

1. Mukufuna mtundu wanji?

Muyenera kuganizira za mtundu wa PV disconnect switch yomwe ikufunika, mwachitsanzo kuti mumvetsetse mphamvu zanu.Slocable ili ndi masiwichi osalumikiza kuyambira pa DC 1000V mpaka 1500V.Ngati mukufuna yankho makonda, titha kuperekanso PV kusagwirizana masiwichi kwa 600V, 800V, 1000V, 1200V kapena 1500V.

2. Voltage ndi Current

Ngati mukufuna kuyika chosinthira cholumikizira cha DC, muyenera kukula kwa omwe akulumikizana nawo kuti muwonetsetse kuti atha kutengera mphamvu zomwe zimaperekedwa kudzera mu gridi yake.

Ngati mukufuna mafunde okwera kwambiri, mufunika kulumikizana kowonjezereka kuti muwathandize kupewa kutenthedwa kwamagetsi.Zosintha zathu za Slocable PV zimayambira pa 1000V, 1200V mpaka 1500 ndipo zimavoteledwa pa 32A ndi 55A.

3. Zikalata za IEC ndi AS

Chinthu china choyenera kuganizira ndikudziwa satifiketi za IEC ndi AS.Ngati wopanga ma switch switch a DC ali ndi ziphaso izi, zikutanthauza kuti kampaniyo ikutsatira malangizo apadziko lonse lapansi popanga PV DC yochotsa zinthu zosinthira.

Mwachitsanzo, mu gawo loyamba la EIC 60204-1: 2016, wopanga amayenera kupereka zosinthira pamanja pa gwero lililonse lamagetsi lomwe likuyikidwa limodzi ndi magawo enaake apangidwe.

4. Njira yoyika

Muyeneranso kuganizira za malo omwe mungakhazikitse chosinthira cha DC disconnect ndi masitayilo okwera omwe ali oyenerera pulogalamu yanu.Kalembedwe kofala kwambiri ndi phiri la mabowo anayi, omangidwa mozungulira ndi mabowo anayi pakona iliyonse.Mawonekedwe awa ndi abwino ngati mukufuna kuyika chosinthira pamalo athyathyathya, chifukwa amalola kuti chosinthiracho chikhale chopepuka momwe mungathere.

Mawonekedwe a Slocable PV DC disconnect switch:

1. Kulumikizana kwa mpeni wodalirika kwambiri ndi chipinda chozizira cha arc yayitali zimatsimikizira kudzipatula kotetezeka kwa magetsi a DC.
2. Wonjezerani chitetezo ndi Slocable's patented "Security Lock" mbali.
3. The Slocable PV disconnect switch series likupezeka mu 2 mpaka 8 pole Mabaibulo ndi zosiyanasiyana kukwera ndi kagwiridwe kasinthidwe kwa OEM ambiri kapena ntchito unsembe munda.

Zosintha za PV izi zayesedwa ndi oyendera ndipo ndi UL508i, TUV (60947-1 & 60947-3), CE ndi CCC zovomerezeka.

Slocable imaperekanso zida zina za solar PV, kuphatikiza zolumikizira za Solar MC4, zonyamula ma fuse za MC4, mabokosi ophatikizira ma photovoltaic ndi oteteza DC.
