Wotsegula Dera Wanzeru LKB3-100

LKB3-100 ndi chotsukira maginito chapadera cha Photovoltaic Grid-Connection Circuit Breaker chomwe chapangidwira kuphatikiza bwino komanso mwanzeru makina a PV ogawidwa. Chimapereka chitetezo chokwanira, kuphatikiza overload, short-circuit, over-voltage, under-voltage, ndi kutayika kwa magetsi. Chinthu chofunikira kwambiri ndi ntchito yake yodzitsekera yokha, yomwe imabwezeretsa mphamvu zokha zinthu zikangoyamba kukhala bwino, zomwe zimathandiza kuti ntchito isagwiritsidwe ntchito mosasamala. Yoyesedwa pa makina a 50Hz, 230V/400V AC okhala ndi mafunde ochokera ku 6A mpaka 100A, imathandizira njira zoyendetsera manual/automatic komanso remote control kudzera pa RS-485/Bluetooth. Ndi makina opirira kwambiri a ma cycle 10,000 komanso kuyika njanji ya DIN yaying'ono, ndi gawo lolimba komanso lofunikira kwambiri pakugwiritsa ntchito mphamvu za dzuwa zamakono.

Kufotokozera kwa Zamalonda

Chotsukira cha LKB3-100 Photovoltaic Grid-Connection Circuit Breaker ndi chipangizo choteteza chapamwamba chomwe chapangidwa makamaka kuti chigwirizane ndi zofunikira za makina ogawa a solar photovoltaic (PV). Ntchito yake yayikulu ndikuteteza chingwe chamagetsi ku overloads ndi short-circuits, pomwe luso lake lalikulu lili pakuwongolera kusinthasintha kwa magetsi a grid komwe ndikofunikira kwambiri pakulumikizana kwa PV.

Imaphatikiza ntchito zambiri zoteteza mu unit imodzi: chitetezo cha over-voltage (ulendo pa 290V ± 10V), chitetezo cha under-voltage (ulendo pa 160V ± 10V), ndi chitetezo cha kutaya mphamvu. Chinthu chanzeru kwambiri ndi ntchito yake yodzitsekera yokha, yomwe imadzipangitsanso kugwira ntchito pambuyo poti vuto la magetsi layamba kugwira ntchito bwino, zomwe zimathandiza kuti ntchitoyo isayang'aniridwe bwino. Luntha ili limakulitsidwa kudzera mu chithandizo cha remote control, monitoring, ndi configuration kudzera mu ma interfaces olumikizirana monga RS-485 ndi Bluetooth.

Pamagetsi, imayesedwa pamakina a 50Hz, yokhala ndi zosankha za 1P+N mpaka 4P. Mphamvu yoyesedwa imayambira pa 6A mpaka 100A, yokhala ndi mphamvu yosweka (Ics) ya 6kA komanso ma curve a C ndi D tripping. Chipangizochi chimapereka kuchedwa kwa maulendo komwe kungakonzedwe pamikhalidwe ya under-voltage/loss-of-voltage (masekondi 0-10), zomwe zimathandiza kusintha kutengera zomwe zimafunika pa gridi. Nthawi yake yogwira ntchito ndi yachangu pamasekondi ≤0.5.

Yopangidwa kuti ikhale yolimba komanso yodalirika, ili ndi mphamvu yolimba yamakina komanso yamagetsi ya ma cycle 10,000. Imagwira ntchito bwino mkati mwa kutentha kwa -25°C mpaka +65°C (ndi malire kuyambira -40°C mpaka +70°C) ndipo ili ndi choyikira njanji cha 35mm DIN chokhazikika kuti chiyike mosavuta. Kuphatikiza chitetezo champhamvu cha dera ndi luso lanzeru la gridi, LKB3-100 ndi gawo lofunikira kwambiri pakuwonetsetsa kuti ma PV okhala m'nyumba ndi m'mabizinesi ndi otetezeka komanso odalirika.
