PV Grid-yolumikizidwa Combiner Box
Zowonetsa Zamalonda
Bokosi lolumikizana ndi gridi ya photovoltaic limaphatikiza zolowetsa za DC mpaka 24 ma cell a photovoltaic motsatizana kukhala chotuluka chimodzi kapena zingapo, ndikutulutsa kulikonse kumakhala ndi ma fuse, zomangira mphezi, ndi zophulitsa madera.Izi zimathandizira mawaya olowera a makabati ogawa a DC ndi ma inverters, kupereka chitetezo ku mphezi, mabwalo amfupi, ndi pansi.Bokosi lolumikizana likupezeka mumitundu iwiri: yanzeru komanso yopanda nzeru.Bokosi loteteza mphezi lanzeru lili ndi gawo loyang'anira mkati mwake lomwe limatha kuyang'anira zomwe zikuchitika pamtundu uliwonse wa cell ya photovoltaic ndi mphamvu yonse yotulutsa mphamvu, komanso kutentha mkati mwa bokosilo, momwe womanga mphezi alili, komanso momwe alili. wa wowononga dera.
Maonekedwe amkati a chipangizocho ndi osavuta komanso omveka bwino, okhala ndi mawaya abwino komanso omveka.Chipangizocho chimakhala chodalirika kwambiri ndipo n'chosavuta kuchisunga.Ikhoza kuikidwa panja pakhoma, ndipo imatha kusinthasintha kumadera osiyanasiyana ovuta.Kuphatikiza pazofunikira zazikuluzikulu, zina zitha kusinthidwa malinga ndi zomwe wogwiritsa ntchito akufuna.
Zogulitsa
★Chitetezo cha bokosi lophatikizira chimafika ku IP65, ndipo chimakhala ndi ntchito zosalowa madzi, zopanda fumbi, zosagwira dzimbiri, komanso zotsimikizira kutsitsi kwa mchere, kukwaniritsa zofunika pakuyika panja:
★ Itha kulumikiza nthawi imodzi mpaka zingwe 24 za batri:
★Pali iliyonse yabwino ndi yoipa ya mndandanda wa batri mu njira iliyonse imakhala ndi fuse yodzipatulira ya photovoltaic kuteteza mndandanda wa zigawo ku zolakwika.Ma fusesi ndi fusesi amaphatikizidwa kuti agwiritsidwe ntchito, kuchepetsa mtengo wokonza wa eni ake ndikuteteza bwino chitetezo cha anthu ogwira ntchito yokonza:
★Pogwiritsa ntchito ma photovoltaic odzipatulira oteteza ma voltage apamwamba, ma terminals abwino ndi oyipa a busbar pambuyo polumikizana amatha kutetezedwa kumtunda, ndipo mphamvu yopitilirabe yogwira ntchito (Uc) imatha kufikira 1000VDC:
★Mphamvu yamagetsi mu bokosi lophatikizira imatha kulumikizana ndi magetsi ochulukirapo a photovoltaic a 1000DCV:
★Magawo owongolera a bokosi lophatikizira amatengera zinthu zodalirika za Honeywell Hall (masensa a DC CT) kuti asonkhanitse deta pamagetsi apano ndi mabasi a chingwe chilichonse cha photovoltaic, kuyang'anira ndi kupeza ma alarm ndi zolakwika zakomweko, ndikuyesa kutentha mkati mwa bokosi lophatikiza, monga komanso kuzindikira momwe zida zotetezera mphezi zilili ndi zowononga ma circuit etc:
★Ili ndi RS485/MODBUS-RTU serial communication kuthekera:
★Pali chitetezo champhezi pazigawo zonse zakunja:
★Ikhoza kulandira kutsitsa kwa magawo kuchokera kuzipangizo zowunikira kwanuko kuti ziwunikidwe ndikuwunikidwa:
★ Mphamvu yogwira ntchito ya bokosi lolumikizira imatha kusankhidwa kuchokera ku 220VAC / DC yakunja kapena magetsi operekedwa ndi bokosi lolumikizana lokha.Ngati magetsi omwe amaperekedwa ndi bokosi lolumikizana lokha agwiritsidwa ntchito, palibe chifukwa chopangira mawaya apadera pamalopo:
