I-Solar Surge Protection Device Slocable

Uyini umgomo wedivayisi yokuvikela ukukhuphuka kwelanga nokuthi ungakhetha kanjani umvikeli ofanele wokushisa kwelanga?

       Idivayisi yokuvikela ukukhuphuka kwelangaluhlobo lwensiza ye-elekthronikhi ehlinzeka ngokuvikeleka kokuphepha kwezinto ezihlukahlukene zikagesi kanye nemigqa yokuxhumana.Lapho amandla aphezulu noma i-voltage kukhiqizwa ngokuzumayo kusekethe kagesi noma isekethe yokuxhumana ngenxa yokuphazamiseka kwangaphandle, ukuvikelwa kwe-pv surge kungaqhuba futhi kuvimbe ngesikhathi esifushane kakhulu, ukuze kugwenywe ukulimala kokuhlinzwa kwezinye izinto ezisesekethe. .Lesi sihloko sigxile ekutheni uyini umgomo wesivikeli sokuhlinza elanga nokuthi ungakhetha kanjani umvikeli ohlinzayo ofanelekile.

Uyini umgomo wedivayisi yokuvikela ukukhuphuka kwelanga?

Amadivayisi okuvikela ukukhuphuka kwelanga abizwa nangokuthi amadivaysi okuvikela umbani.Ngokwamazinga e-IEC kazwelonke, asetshenziswa kakhulu ukukhawulela ukugcwala ngokweqile kanye nokugeleza ngokweqile kulayini.Umvikeli we-solar surge unomphumela wokuvikela osebenzayo emishinini ye-elekthronikhi, uthwala umbani olindelekile wamanje.Ngemuva kokucindezelwa okuphezulu kwesivikeli se-pv surge, imunca ngempumelelo imvamisa yamandla eqhubekayo yamanje ekhiqizwa ngemuva kokudlula kombani, futhi izodlula kulayini wamandla kanye nolayini wokudlulisa isignali.I-overvoltage esheshayo noma i-overcurrent icindezelwa ngaphakathi kwe-voltage isisetshenziswa nesivikeli esingamelana nayo, noma umbani omkhulu ungeniswa emhlabathini ukuze kuvikelwe okokusebenza.

Idivayisi evamile yokuvikela ukukhuphuka kwelanga iletha okwamanje kusuka kusokhethi yamandla kuya kumishini eminingi kagesi neye-elekthronikhi exhunywe ebhodini lamandla.Uma i-surge noma i-spike ibangela ukuthi i-voltage idlule izinga elamukelekayo, i-Solar SPD izodlulisela amandla amanje ngokweqile emhlabathini we-outlet yamandla.

Emishinini evame kakhulu yokuvikela ukukhuphuka kwelanga, kunengxenye ebizwa ngokuthi i-metal oxide varistor, esetshenziselwa ukudlulisa i-voltage ngokweqile.I-MOV yakhiwe izingxenye ezintathu: Phakathi nendawo kukhona insimbi ye-oxide, futhi ama-semiconductors amabili axhunywe kugesi kanye nomhlabathi.

Lawa ma-semiconductors anokumelana okuguquguqukayo okushintsha ngokushintsha kwamandla kagesi.Uma i-voltage ingaphansi kwenani elithile, ukunyakaza kwama-electron ku-semiconductor kuzokhiqiza ukumelana okuphezulu kakhulu.Ngokuphambene nalokho, lapho i-voltage idlula leli nani elithile, ukunyakaza kwama-electron kuzoshintsha futhi ukumelana kwe-semiconductor kuzoncishiswa kakhulu.

Ungakhetha kanjani idivayisi efanele yokuvikela ukukhuphuka kwelanga?

Lapho uthenga idivayisi yokuvikela ukukhuphuka kwelanga, ngokuvamile udinga ukuqaphela kakhulu.Isizathu esikhulu ukuthi imakethe yamanje igcwele imikhiqizo engenawo umphumela.Indlela engcono kakhulu yokuthenga umkhiqizo ofanelekayo ngokuyinhloko ukucwaninga imodeli ethile.Yiqiniso, kufanele unake ngokucophelela amamaki ekhwalithi amaningana, futhi ngesikhathi esifanayo kufanele uqonde kangcono izinga lokusebenza lomkhiqizo.

Lapho ukhetha, kufanele uhlole intengo ehambisanayo.Ngaphansi kwezimo ezijwayelekile, ungalindeli okuningi kakhulu ngenani eliphansi le-DC SPD.Isizathu esiyinhloko ukuthi la madivayisi ngokuvamile asebenzisa ama-MOV alula futhi angabizi, ngakho umthamo wawo ulinganiselwe.Ngesikhathi sokusetshenziswa kwansuku zonke, uma kwenzeka ukuqhuma okukhulu noma i-spike, isistimu yomsebenzisi ngeke ikwazi ukuvikela isistimu yomsebenzisi.

Vele, i-solar yokuvikela i-dc enenani eliphezulu ayisho ikhwalithi enhle.Kubathengi abafuna ukukhetha umvikeli ofaneleka kakhulu, kufanele bahlole izimpawu ezihambisanayo.Lokhu kubalulekile uma kuqhathaniswa.

Lesi sihloko sigxile kumgomo wedivayisi yokuvikela ukukhuphuka kwelanga kanye nendlela yokukhetha umvikeli ofanele wokushisa kwelanga.Ngalezi zinto, wonke umuntu kufanele akwazi ukuqonda umgomo we-solar DC SPD.Indima yabavikeli bokuhlinzwa isobala, kodwa wonke umuntu kufanele anake ukukhetha ukuthenga ngekhwalithi enhle.
