IEC 60364-7-712: 2017

Kukhazikitsa kwamagetsi kwamagetsi otsika pang'ono - Gawo 7-712: Zofunikira pakukhazikitsa kwapadera kapena malo - Solar photovoltaic (PV) magetsi

International Electrotechnical Commission (IEC) yatulutsa IEC 60364-7-712: 2017 ya "Makina ochepa amagetsi - Gawo 7-712: Zofunikira pakukhazikitsa kwapadera kapena malo - Solar photovoltaic (PV) magetsi".

Kufotokozera: "IEC 60364-7-712: 2017 imagwira ntchito pakuyika kwamagetsi kwamakina a PV omwe amaperekedwa kuti azipereka zonse kapena gawo loyikapo. Zida zopangira PV, monga zida zina zilizonse, zimangoyang'aniridwa pokhapokha pakusankhidwa kwake ndikugwiritsa ntchito pakuyikako. Kusindikiza kwatsopanoku kumaphatikizaponso kukonzanso kwakukulu ndi kukulitsa, poganizira zomwe zachitika pomanga ndi kuyendetsa makina a PV, ndi chitukuko chaukadaulo, kuyambira pomwe kope loyamba la muyezowu lidasindikizidwa. "

Kukula:

Gawo ili la IEC 60364 limagwira pamagetsi opangira makina a PV omwe cholinga chake ndi kupereka zonse kapena gawo lina la kukhazikitsa.

Zida zokhazikitsa PV, monga chinthu china chilichonse chogwiritsira ntchito, zimangogwira ntchito mpaka pomwe amasankhidwa ndikugwiritsa ntchito kukhazikitsa.

Kukhazikitsa kwa PV kumayambira pa module ya PV kapena seti ya ma PV yolumikizidwa motsatana ndi zingwe zawo, zoperekedwa ndi wopanga module wa PV, mpaka kwa ogwiritsa ntchito kapena malo ogwiritsira ntchito (point of coupling wamba).

Zofunika za chikalatachi zimagwiranso ntchito

• Makina a PV osalumikizidwa ndi njira yogawa magetsi kwa anthu,
• Kuyika kwa PV mofananira ndi njira yogawa magetsi kwa anthu,
• Kukhazikitsa kwa PV ngati njira ina yothandizira magetsi kwa anthu,
• kuphatikiza koyenera pamwambapa. Chikalatachi sichikutanthauza zofunikira pakukhazikitsa mabatire kapena njira zina zosungira magetsi.

Dziwani 1 Zowonjezera zowonjezera pakukhazikitsa kwa PV yokhala ndi mphamvu yosungira batire mbali ya DC ikuwunikidwa.

Dziwani 2 Chikalatachi chimafotokoza za chitetezo cha magulu a PV omwe amayamba chifukwa chogwiritsa ntchito mabatire m'makina a PV.

Kwa makina ogwiritsa ntchito otembenuza DC-DC, zowonjezera zowonjezera pamagetsi ndi kuchuluka kwaposachedwa, kusintha, ndi zida zoteteza zitha kugwiritsidwa ntchito. Izi ndizofunikira.

Cholinga cha chikalatachi ndi kuthana ndi zofunikira pakapangidwe kazotetezedwa chifukwa cha kukhazikitsa kwa PV. Makina a DC, ndi magulu a PV makamaka, amabweretsa zoopsa zina kuphatikizira zomwe zimachokera pamakonzedwe amagetsi a AC, kuphatikiza kuthekera kopanga ndikusunga ma arcs amagetsi ndi mafunde omwe sali akulu kuposa magwiridwe antchito wamba.

M'makina olumikizidwa ndi PV olumikizidwa ndi zida zofunikira kuti chikalatachi chikhale chitetezo, zimadalira PCE yokhudzana ndi magulu a PV kutsatira zofuna za IEC 62109-1 ndi IEC 62109-2.
