Mune photovoltaic system, kutonhora kwe ACcableinosiyanawo nekuda kwenzvimbo dzakasiyana umo mitsetse yakaiswa.Nharaunda pakati pe inverter uye grid yekubatanidza nzvimbo yakasiyana, zvichikonzera kudonha kwakasiyana kwevoltage patambo.Zvese tembiricha uye kudonha kwevoltage zvinokanganisa kurasikirwa kwehurongwa.Naizvozvo, zvinodikanwa kugadzira zvine musoro dhayamita yewaya yekubuda ikozvino kweiyo inverter, uye kunyatso funga zvinhu zvakasiyana-siyana, kuitira kuti uderedze mari yekutanga kweiyo photovoltaic magetsi chiteshi uye kuderedza mutsara kurasikirwa kwehurongwa.
Paunenge uchigadzira nekusarudza tambo, tekinoroji paramita seyakayerwa ikozvino kutakura simba, voltage, uye tembiricha yetambo zvinonyanya kutariswa.Panguva yekuisa, iyo yekunze dhayamita, bending radius, kudzivirira moto, nezvimwe zvetambo zvinotariswa zvakare.Paunenge uchiverenga mutengo, funga mutengo wetambo.
1. Ikozvino inobuda ye inverter inofanirwa kuenderana neiyo ikozvino kutakura kugona kwetambo
Ikozvino yakabuda ye inverter inotarirwa nesimba.Iyo imwe-phase inverter ikozvino = simba / 230, iyo yechitatu-phase inverter ikozvino = simba / (400 * 1.732), uye mamwe inverters anogona zvakare kuwandisa ne1.1 nguva.
Ikozvino kutakura kugona kwetambo kunotarirwa nezvinhu, waya dhayamita uye tembiricha.Kune marudzi maviri etambo: waya yemhangura uye aluminium wire, imwe neimwe inobatsira.Kubva pakuona kwekuchengetedza, zvinokurudzirwa kushandisa waya yemhangura kune inobuda AC tambo ye inverter, uye BVR yakapfava waya inowanzosarudzwa kune imwe-chikamu.Waya, PVC insulation, copper core (nyoro) jira waya voltage kirasi iri 300/500V, matatu-chikamu sarudza 450/750 voltage (kana 0.6kV/1kV) kirasi YJV, YJLV irradiated XLPE insulated PVC Sheathed simba tambo, hukama pakati peiyo cutoff ye conductor uye tembiricha, kana ambient tembiricha yakakwira kupfuura 35 ° C, ikozvino inobvumirwa inofanira kuderedzwa ne10% pakuwedzera kwe5 ° C kwese kwekushisa;kana ambient tembiricha yakaderera pane 35 ° C, tembiricha Kana tembiricha inodonha ne5 ° C, inobvumirwa ikozvino inogona kuwedzerwa neinenge 10%.Kazhinji, kana tambo yakaiswa munzvimbo yemukati inofefetera.
2. Cablekugadzirwa kwehupfumi
Mune dzimwe nzvimbo, inverter iri kure kure nenzvimbo yekubatanidza grid.Kunyange zvazvo tambo inogona kusangana nezvinodiwa zveyazvino kutakura simba, kurasikirwa kwemutsara kwakakura nekuda kwetambo refu.Iyo yakakura iyo warp, iyo inoderera kushomeka kwemukati.Asi zvakare funga mutengo wetambo, iyo yekunze dhayamita ye inverter AC inobuda yakavharwa materminal.
