Iyo Mamiriro uye Makuru Mabasa eSolar Panel Yekubatanidza Bhokisi

       Solar panel yekubatanidza mabhokisianoshandiswa nevanogadzira magetsi kudzivirira tambo kubva pakuvhundutswa kwenyama uye kurumwa netumbuyu kuburikidza nekushandisa matambo etambo kunze kwetambo.Uye pakubatanidzwa kwetambo (kana pakona yepombi yetambo), shandisa bhokisi rejunction sekuchinja.Machubhu maviri etambo akabatanidzwa kune junction box, uye tambo dziri mukati mechubhu dzakabatana mukati mejinji bhokisi.Solar yekubatanidza bhokisi inoita basa rekudzivirira nekubatanidza tambo.

Basa reSolar junction box nderekubatanidza magetsi anogadzirwa nePV module kune yekunze wiring.Sezvo solar panels dzinowanzoda kushandiswa munzvimbo dzakaoma dzekunze uye dzine waranti inosvika makore makumi maviri nemashanu, solar panels inewo zvakakwirira zvinodikanwa zvekubatanidza mabhokisi.Pamusoro pekuona kuvimbika kwekubatana, kuve nechokwadi chekuchengetedzwa kwemukati wiring, solar panel yekubatanidza bhokisi inodawo kuve neakakwira anti-kuchembera, anti-UV kugona;kuva nehuwandu hwepamusoro hwemvura uye guruva, kazhinji kuwana IP67 kana kupfuura;inogona kumira yakakwira ikozvino (kazhinji inoda kupfuura 20A), yakakwira voltage (kazhinji 1000 volts, zvigadzirwa zvakawanda zvinogona kusvika 1500 volts);shandisa dzakasiyana tembiricha (-40 ℃ ~ 85 ℃), yakaderera kushanda tembiricha uye zvakatevedzana zvinodiwa.Zvakare, kudzikisira uye kudzivirira iyo inopisa nzvimbo mhedzisiro, madhiodhi anosanganisirwa mukati meiyo solar junction bhokisi.

Kuumbwa kwepv panel junction bhokisi: chivharo chebhokisi (kusanganisira chisimbiso mhete), muviri webhokisi, zviteshi, diode, tambo, uye zvinobatanidza.

Chimiro cheSolar Panel Connection Bhokisi

1. Bhokisi remuviri uye chivharo chebhokisi rekusangana

Iyo yakadzika zvinhu zvebhokisi muviri uye chivharo che solar panel yekubatanidza bhokisi inowanzoshandiswa PPO, iyo ine zvakanakira kusimba kwakanaka, kupisa kwakanyanya kupikisa, kusapisa, kusimba kukuru uye yakanakisa magetsi emagetsi.Pamusoro pezvo, PPO inewo zvakanakira kupfeka kuramba, kusiri muchetura, kusvibiswa kwemhepo, kunaka kwemamiriro ekunze, etc. PPO ine imwe yediki diki dielectric constants uye dielectric kurasikirwa pakati peinjiniya mapurasitiki, uye inenge isingabatsirwe nekushisa uye humidity, inobvumira. inofanira kushandiswa munzvimbo dzakaderera, dzepakati nepamusoro dzemagetsi emagetsi.Iyo isina kugadziridzwa yakachena PPO ine yakakwira melt viscosity, isina kunaka processability uye moldability, uye haigone kuumbwa nemuchina wekuumba jekiseni.Kuti ugadzirise dambudziko iri, PPO inogona kugadziridzwa nenzira dzemuviri kana dzemakemikari, uye iyo yakagadziridzwa PPO inonzi MPPO.Inopisa inonyungudika mhando MPPO inoumbwa nemuchina wekuumba jekiseni kuti ugadzire muviri webhokisi.Nzira yekugadzira yevhavha yakafanana nebhokisi rebhokisi, chete mold yakasiyana.Kuti uvandudze kushanda kwemvura, chivharo chichava nechisimbiso chakagadzirwa nesilicone.

2. Terminal

Rutivi rwekupinza rweterminal rwakabatana kune sink bar ye solar panel, uye divi rekubuda rakabatana netambo.Zvinhu zvechigumisiro zvinowanzoita mhangura yakachena kana mhangura yakanamirwa, tin-plated mhangura imhangura ine simbi yakatetepa yakanamwa pamusoro.Tin inonyanya kuita basa mukuchengetedza mhangura kudzivirira mhangura kubva pakuiswa oxidized kuti iumbe mhangura yakasvibira kukanganisa conductivity.Panguva imwecheteyo, iyo yakaderera kunyungudika kweti, nyore kupinza, uye yakanaka magetsi conductivity, unogona zvakare kushandisa chromium-yakapfatwa mhangura kuita iyo terminal.

3. Diode

Diode dzine hunhu hwemuperekedzi mumwe chete.Madhiodhi anogona kuverengerwa seanogadzirisa diode, anokurumidza diodes, voltage regulator diode uye mwenje emitting diode.

4. PV Cable

Tambo dzinowanzo shandiswa dzine mhangura kana tinned conductor mukati uye maviri ekudzivirira akaturikidzana kunze, anoti polyvinyl chloride (PVC) insulation pamwe nePVC bhachi, asi PVC haizadzise zvinodiwa pakuchembera uye ine halogen, iyo inoburitsa chlorine gasi kana yapiswa uye isina kunyanya kuchengetedzeka.Photovoltaic tambo dzinoda irradiated cross-linked polyolefins mukuwedzera kune conductor (irradiation cross-linking tekinoroji inoreva kuchinjika-kubatanidza kuita kwema macromolecules kunowanikwa kuburikidza neradiation, kuitira kuti mutsara wepolymer ive polima ine matatu-degree space network chimiro, kuti tembiricha yayo yenguva refu inobvumidzwa yekushanda inowedzerwa kubva pa70°C kusvika pa90°C, uye tembiricha inobvumidzwa yepfupi-dunhu inowedzerwa kubva pa140°C kusvika painodarika 250°C, ichichengeta magetsi ayo ekutanga akanakisa nekuvandudza kushandiswa chaiko kwekuita. ) Mukati me photovoltaic tambo ine waya yemhangura ine cross-sectional nzvimbo ye4mm2.Kana iyo yemazuva ano ye solar panel (isingasviki gumi amps) yakaverengerwa, waya yemhangura ye2.5mm2 inokwana, asi tichifunga kuti solar panels dzinowanzoshanda pasi pemamiriro ekushisa kwakanyanya, kana tambo yetambo yadzikiswa uye system iripo yakakwira zvakanyanya. , nzvimbo yakakura yemhangura yemhangura yemhangura inofanira kushandiswa kuve nechokwadi chekuchengetedzwa kwehurongwa.

5. Chibatanidza

Zvibatanidza zvinovharira kana kuzviparadzanisa pakati pemaseketi, kuvharira kuyerera kweazvino kuitira kuti dunhu riite basa rayo.Peya yekubatanidza inoumbwa neyechirume chinongedzo uye chechikadzi chinongedzo, uchishandisa PPO sechinhu chinodzivirira.Mukono wechirume unoshandiswa kune iyo yakanaka terminal yechikamu uye iyo yechikadzi yekubatanidza inoshandiswa kune iyo isina kunaka terminal.

6. Potting Glue

Mazhinji solar ekubatanidza mabhokisi anoshandisa silicone potting adhesives kuchengetedza yavo yemukati zvikamu uye kunatsiridza kupisa kwekuita.Junction bhokisi potting adhesive inonyanya kubva pane maviri-chikamu silicone.Maviri-component silicone anoumbwa neA, B marudzi maviri eglue, Mhando yeglue inonzi base glue, B mhando yeglue inonzi inoporesa agent.Kana iyo AB yemhando glue yakasanganiswa mune imwe chikamu isati yashandiswa, inoiswa mubhokisi rejunction yekurapa mushure mekusanganisa.Kusanganisa maitiro kunofanirwa kuve nekuchenjerera kuderedza kusanganiswa kwemhepo.Silicone potting adhesive inogona kurapwa pakamuri tembiricha (25 ℃) kana nekudziya.Tembiricha yekamuri yekurapa mapoto ekunamatira anogona zvakare kukwidziridzwa nekudziya.Iyo inorapa mumiriri inofanirwa kuve yakasanganiswa isati yashandiswa, sezvo kumwe kunaya kunogona kuitika panguva yekusununguka uye kuchengetedza.Mushonga unorapa unowanzoita nekunyorova mumhepo, saka kutarisirwa kwakanyanya kunofanirwa kutorwa kudzivirira kusangana nemhepo usati washandisa.

Basa reSolar Connection Bhokisi

1. MPPT basa: gadzirisa iyo yakanyanya simba yekutevera tekinoroji uye chigadziriso chigadziriso chepaneru yega yega kuburikidza nesoftware uye hardware, tekinoroji iyi inogona kuwedzera mukana wekuvandudza simba rekugadzira simba kuderedzwa kwechiteshi chemagetsi chinokonzerwa nehunhu hweakasiyana mapaneru arrays, uye kuderedza. iyo "barrel effect" pamagetsi ekugadzira magetsi, inogona kuwedzera zvakanyanya simba rekugadzira simba rechiteshi chemagetsi.Kubva pamhedzisiro yebvunzo, iyo yakanyanya simba kugadzirwa kwesimba kweiyo system inogona kutowedzerwa ne47.5%, ichiwedzera kudzoka pakudyara uye kuderedza zvakanyanya nguva yekubhadhara.

2. Intelligent shutdown function pasi pemamiriro asina kujairika akadai semoto: Kana pakaitika moto, solar connection box's built-in software algorithm ichashanda pamwe nehardware circuit kuona mukati megumi remamilliseconds kana abnormality yaitika, uye tora danho cheka chinongedzo pakati pepaneru yega yega, iyo voltage ye1000V ichidzika kusvika ku40V inogamuchirwa nevanhu voltage kuti ive nechokwadi chekuchengetedzwa kwevanodzima moto.

3. Kushandiswa kweMOSFET thyristor Integrated control tekinoroji, panzvimbo yechinyakare Schottky diode.Kana shading ikaitika, unogona pakarepo kutanga iyo MOSFET bypass ikozvino kuchengetedza kuchengetedzeka kwepaneru, nepo MOSFET nekuda kweiyo yakasarudzika yakaderera VF maitiro, kuitira kuti kupisa kwese chizvarwa mubhokisi rejunction chingori chikamu chimwe chete mugumi cheyakajairwa junction bhokisi. , teknolojia inowedzera zvakanyanya hupenyu hwebasa rebhokisi rekubatanidza, kuchengetedza zviri nani hupenyu hwebhatiri.
