Iyo inorwadza poindi ye photovoltaic mc4 yekubatanidza yekuisa: Crimping

Nekukurumidza kukura kwekuparadzirwa, kunyanya mhuri photovoltaic market mumakore achangopfuura, zvinetso zvehutano zve photovoltaic systems zvave zvichinyanya kuzivikanwa.Moto uri mu photovoltaic system hauzongoisa pangozi kuchengetedzwa kwemunhu, asiwo une simba rakaipa pamhizha.Zvinoenderana nemishumo yekutsvagisa yekune dzimwe nyika, yekubatanidza mutual kuisa uye isina kujairika yekubatanidza yekuisa chinzvimbo chekutanga neyechitatu zvikonzero zvemoto.Ichi chinyorwa chinotarisa kuongororwa kwekusagadzikana kwekuiswa kwezvibatanidza, kunyanya crimping ye photovoltaic tambo uye yekubatanidza simbi core, kuitira kupa vashandisi imwe referensi, kuchengetedza iyo photovoltaic system, uye kudzivirira mabhenefiti evashandisi.

Market Situation

Mune photovoltaic power generation system, photovoltaic connectors inonyanya kushandiswa muzvikamu, mabhokisi ekubatanidza, inverters uye zvinobatanidza pakati pavo, zvizhinji zvacho zvakaiswa mufekitari, uye crimp quality inovimbika.Inenge 10% yezvibatanidza zvakasara zvinoda kuiswa nemaoko panzvimbo yeprojekti, kunyanya kureva kudiwa kwekuisa zvibatanidza kumativi ose maviri e photovoltaic cable inobatanidza chimwe nechimwe.Zvinoenderana neruzivo rwemakore mazhinji ekushanya kwevatengi, nekuda kwekushaikwa kwekudzidziswa kwevashandi vekuisa pasaiti uye nekushandiswa kwehunyanzvi hwekuita crimping maturusi, crimping zvisirizvo zvakajairika, sezvaratidzwa pazasi.

Mhando uye maitiro esimbi cores

Nheyo yesimbi ndiyo mutumbi mukuru wekubatanidza uye inonyanya kukosha nzira yekuyerera.Parizvino, iyo yakawanda yakawanda ye photovoltaic connectors pamusika inoshandisa "U"-yakaita sesimbi yesimbi, iyo yakadhindwa uye inoumbwa kubva papepa remhangura, inozivikanwawo sesimbi yakadhindwa.Nekuda kwemaitiro ekudhinda, iyo "U"-yakaita sesimbi musimboti haingove nehunyanzvi hwekugadzira, asi zvakare inogona kurongeka mumaketani, ayo akanyatsokodzera kugadzirwa kwewaya hanzi.

Mamwe ma-photovoltaic connectors anoshandisa "O"-shaped metal core, iyo inoumbwa nekuchera maburi kumativi ose emudonzvo wemhangura yakaonda, iyo inonziwo machined metal core.Iyo "O"-yakaumbwa nesimbi musimboti inogona chete kuremerwa yega yega, iyo isingakodzeri kushandiswa mune otomatiki michina.

【Mufananidzo 2: Metal core type】

Iko kune zvakare isingawanzo simbi musimboti iyo isina crimp-isina, iyo yakabatana netambo nespring sheet.Sezvo pasina maturusi ecrimping anodiwa, kuisirwa kuri nyore uye kuri nyore.Zvisinei, kubatanidzwa kweshizha rechirimo kuchaita kuti pave nekurwisana kukuru, uye kuvimbika kwenguva refu hakugoni kuvimbiswa.Mamwe masangano ezvitupa zvakare haatenderi rudzi urwu rwesimbi musimboti.

Ruzivo rwekutanga rwecrimping

Crimping ndeimwe yeakanyanya uye akajairika nzira dzekubatanidza.Kusaverengeka crimping kunoitika zuva nezuva.Panguva imwecheteyo, crimping yakaratidza kuve yakakura uye yakavimbika yekubatanidza tekinoroji.

Crimping process

Kuvimbika kwecrimping kunoenderana zvakanyanya nezvishandiso uye mashandiro, ese ari maviri anoona kana yekupedzisira crimping mhedzisiro inosangana nezvinodiwa zveyero.Tora "U"-yakaumbwa nesimbi core semuenzaniso.Iyo inongova yemhangura tin-plated zvinhu uye inoda kubatanidzwa kune photovoltaic tambo necrimping.Iyo crimping process ndeiyi inotevera:

【Mufananidzo 3: Kuita crimping】

Hazvina kuoma kuona kuti "U"-yakaita simbi core crimping inzira iyo apo kureba kwecrimping kunoderera zvishoma nezvishoma (apo simba rekurovera richiwedzera zvishoma nezvishoma), pepa remhangura rakaputirwa netambo waya yemhangura inomanikidzwa zvishoma nezvishoma.Mukuita uku, kutonga kwecrimping kureba kunotarisisa kunaka kwecrimping.Kudzora kwehupamhi hwecrimp hakuna kunyanya kukosha, nekuti iyo crimp inofa inosarudza kukosha kwehupamhi.

Crimp urefu

Vanhu vazhinji vanoziva kuti crimping yakanyanyisa kusununguka kana kusimba zvakanyanya haina kunaka, saka sezvo crimping inofambira mberi, kureba kwecrimping kunofanirwa kudzorwa zvakadii?Mukuwedzera, zviratidzo zviviri zvakakosha zvehutano, zvinoti kudhonza-kubvisa simba uye conductivity yemagetsi, zvinoshanduka sei panguva iyi?

[Mufananidzo 4: Kudhonza-kubvisa simba uye kureba kwecrimp]

Sezvo kureba kunoderera zvishoma nezvishoma, simba rekudhonza-kubva pakati petambo nesimbi yesimbi ichawedzera zvishoma nezvishoma kusvika yasvika pa "X" pamufananidzo uri pamusoro.Kana kureba kwecrimping kukaramba kuchidzikira, simba rekudhonza rinoramba richidzikira nekuda kwekuparadzwa zvishoma nezvishoma kwechimiro chetambo yemhangura.

[Mufananidzo 5: Conductivity uye kureba kwecrimp]

Mufananidzo uri pamusoro unotsanangura maitiro emagetsi enguva refu yecrimping.Iyo yakakura kukosha, zviri nani kufambiswa kwemagetsi, uye zvirinani maitiro emagetsi etambo nesimbi core connection."X" inomiririra yakanakisa poindi.

Kana maviri ari pamusoro apa macurves akaiswa kumusoro pamwe chete, tinogona kuwana mhedziso nyore:

        TheKureba kwepamusoro kunogona kungove kutarisisa kwakadzama kwekudhonza-kure simba uye conductivity, uye kukosha munzvimbo iri pakati pemapoinzi maviri akanakisa., sezvinoratidzwa pasi apa.

Crimping quality evaluation

Nzira dzekutonga dzinowanzo shandiswa muindasitiri ndedzinotevera:

∎ Kureba/kufara kunogona kuyerwa ne vernier caliper mukati mechikamu chakatsanangurwa;

■ Simba rekudhonza, kureva kuti, simba rinodiwa kudhonza kana kuputsa tambo yemhangura kubva panzvimbo yekucheka, yakadai se4mm2 cable, IEC 60352-2 inoda zvishoma 310N;

■ Kupokana, kutora 4mm2 tambo semuenzaniso, IEC 60352-2 inoda kushorwa pacrimp kuve isingasviki 135 microohms;

■ Kuongororwa kwechikamu-chepakati, kucheka kusingaparadzi kwenzvimbo yecrimping, kuongororwa kwehupamhi, kureba, chiyero chekumanikidza, symmetry, kuputika uye burrs, nezvimwe.

Kana iri yekuburitsa mudziyo mutsva kana crimping nyowani inofa, mukuwedzera kune ari pamusoro mapoinzi, zvakare inofanirwa kutarisa kugadzikana kwekupokana pasi pemamiriro ekushisa bhasikoro, tarisa kune yakajairwa IEC 60352-2.

Crimping tool

Iyo yakawanda yakawanda ye photovoltaic connectors inoiswa mufekitari kuburikidza nemagetsi emagetsi, uye crimp quality yakakwirira.Nekudaro, kune zvinongedzo zvinofanirwa kuiswa panzvimbo yeprojekiti, crimping inogona chete kuitwa ne crimping pliers.Iyo yepakutanga nyanzvi crimping pliers inofanirwa kushandiswa kugadzira crimping.Zvakajairika vise kana tsono-mhino pliers haigone kushandiswa kukwenya.Kune rimwe divi, mhando yecrimping yakaderera, uye iyi zvakare inzira isingazivikanwe nevagadziri vekubatanidza uye masangano ezvitupa.

Irregular crimping ngozi

Kusa crimping kunogona kutungamira mukusatevedzera zvakatemwa, kusagadzikana kubata kuramba, uye kutadza kuvhara.Icho chinhu chikuru chengozi chinokanganisa basa rose uye purofiti yemagetsi emagetsi e photovoltaic.

Summary

■ Chibatanidza chikamu chiduku, asi chichakanganisa kushanda kwekushanda kweprojekti ye photovoltaic.Kupindirana nemhando kazhinji kunoreva kurasikirwa kwakanyanya kunotevera uye njodzi, izvo zvingadai zvakadziviswa;

■ Nekuiswa kwe photovoltaic connectors, iyo crimping link ndiyo inonyanya kukosha, uye inokurudzirwa kushandisa hunyanzvi hwekuita crimping zvishandiso.Kune vanoisa mainjiniya, crimping kudzidziswa chinhu chakakosha chinongedzo.
