Chii Chinofanira Kufungwa Usati Watenga PV DC Dimbura Chinja?

Mukuisa PV, iyoDC disconnect switchakafanana neairbag mumotokari.Iyo IEC 60364-7-712 yakajairwa inoda kushandiswa kwePV DC bvisa ma switch pakati pePV array uye inverter.Slocable DC disconnect switch yakanyatsogadzirirwa kubvisa DC/AC inverters kubva kune solar panel arrays.Isu tinopa PV yekubvisa ma switch emagetsi anosvika ku1500 V DC.Inogona kushandiswa kugadzira yakazvimirira yekuchinjisa mapoinzi sezvinodiwa neVDE 6012, semuenzaniso, kubvumira kubviswa kwakachengeteka kwemainverters asina kukwana.Yese DC chinja disconnector switches pamatanda maviri uye akakodzera kune akafukunurwa masisitimu.

Imba yePV disconnect switch yakagadzirira kuiswa uye inopa kushanda ikozvino kwe30 A pa1000 V/1500 V DC.Inowanikwa mune mbiri uye ina tambo pamwe neaviri akajairika ekubatanidza mhando dzekubatanidza.MC4 kana metric cable glands inobvumira kubatanidzwa kwakatsetseka mune akasiyana system concepts.Iyo DC disconnect switch enclosure ine kirasi yekudzivirira IP66 uye saka yakanyatsokodzera kuisirwa kunze.Basa rekuvhara rinopa kudzivirira panguva yebasa nekugadzirisa.Iyo pressure compensation element inodzivirira condensation kubva pakuunganidza uye nekudaro inodzivirira kutadza nekuda kwemheni.

Chii Chinofanira Kutariswa Usati Watenga PV Disconnect Switch?

1. Unoda rudzii?

Iwe unofanirwa kufunga nezvemhando yePV yekubvisa switch inodiwa, semuenzaniso kuti unzwisise zvaunoda simba.Slocable ine disconnect switch kubva kuDC 1000V kusvika 1500V.Kana iwe uchida mhinduro yakagadziridzwa, tinogonawo kupa PV disconnect switch ye600V, 800V, 1000V, 1200V kana 1500V.

2. Voltage uye Iyezvino

Kana iwe uchida kuisa DC disconnect switch, iwe unofanirwa kukura mabiko ayo kuti uone kuti inokwanisa kugamuchira simba rinofambiswa kuburikidza negridi rayo.

Kana iwe uchida macurrents akakwira, iwe unozoda mamwe macontacts akawanda kuti uvatsigire kudzivirira kupisa kwemagetsi system.Yedu Slocable PV disconnect switch inotangira pa1000V, 1200V kusvika 1500 uye yakayerwa pa32A ne55A.

3. IEC uye AS zvitupa

Chimwe chinhu chekufunga nezvacho kuziva iyo IEC uye AS zvitupa.Kana DC disconnect switch inogadzira ine zvitupa izvi, zvinoreva kuti kambani iri kutevera nhungamiro dzepasi rose pakugadzira PV DC inobvisa zvigadzirwa zvekuchinja.

Semuyenzaniso, muchikamu chekutanga cheEIC 60204-1:2016, mugadziri anodiwa kuti ape maswiti anofambiswa nemaoko ega ega guru remagetsi arikuiswa pamwe chete nemagadzirirwo akaitwa.

4. Kuisa nzira

Iwe zvakare unozofanirwa kufunga nezve yakasarudzika nzvimbo yekumisikidza iyo DC disconnect switch uye iyo yekumisikidza chimiro inokodzera application yako.Chimiro chinonyanyozivikanwa igomo remaburi mana, rakavakwa muskweya patani nemakomba mana ekukona mukona yega yega.Iyi dhizaini yakanaka kana iwe uchifunga kukwidza switch pane yakati sandara, sezvo ichibvumira switch kuti iite senge ichiita.

Zvimiro zveSlocable PV DC disconnect switch:

1. Yakavimbika zvakanyanya kumucheto kwebanga uye yakareba arc inotonhorera kamuri inovimbisa kuparadzaniswa kwakachengeteka kweDC voltage.
2. Wedzera chengetedzo neSlocable's patented "Security Lock" chimiro.
3. The Slocable PV disconnect switch series inowanikwa mu2 kusvika ku8 pole versions uye mune zvakasiyana-siyana zvekuisa uye kubata zvigadziriso zveOEM yakawanda kana minda yekuisa zvikumbiro.

Aya maPV switch akaedzwa nevanoongorora uye ari UL508i, TUV (60947-1 & 60947-3), CE uye CCC dzakasimbiswa.

Slocable inopawo zvimwe solar PV accessories, zvinosanganisira Solar MC4 zvibatanidza, MC4 fuse holders, photovoltaic junction mabhokisi uye DC surge vadziviriri.
