Inethiwekhi ye-two-in-one isibambisi sombani
Inethiwekhi yamandla ebopha umbani we-2-in-one, inethiwekhi yokubopha umbani okubili-in-one kanye nesivikeli sokuhlinza se-two-in-one siklanyelwe ngokuvumelana namazinga e-IEC kanye ne-GB, asetshenziselwa ikakhulukazi ukuvikelwa kwe-lightning electromagnetic pulse (LEMP) ehlukahlukene. Ikhamera yenethiwekhi ye-HD nemigqa yesignali yenethiwekhi, futhi iyizivikeli zokuhlinza ezisebenzayo eziningi.
Izici zokubopha umbani okubili-kokukodwa:
1. ikhamera yenethiwekhi yokubopha umbani okubili-kokukodwa inomthamo omkhulu wamanje: 10KA (8/20μS), impendulo yesivinini (10-12ns) nokulahlekelwa okuphansi;
2. Umqondo wokuklama wokunikezwa kwamandla okubili kokukodwa kanye nokuvikelwa kombani wenethiwekhi akuthathi isikhala futhi kufanelekile ukuvikela ukukhuphuka kwamakhamera enethiwekhi ahlukene anencazelo ephezulu;
3. Ingavimbela ngempumelelo ukulimala kwemishini okubangelwa ukwanda ngokushesha komehluko ongaba khona phakathi kokunikezwa kwamandla ekhamera nezinto zenethiwekhi;
4. Ukuvikelwa kochungechunge lwezigaba ezimbili kwamukelwa ngaphakathi, ngengcindezi ephansi eyinsalela nempilo ende yesevisi;
5. Imbobo yokuvikela ukukhuphuka kwamandla inenkomba yokuhluleka kwe-LED (okuluhlaza: okuvamile; Cisha: akuvumelekile);
6. Ikhamera yenethiwekhi yokuvikela umbani ezimbili-in-one ithatha isakhiwo esihlanganisiwe, usayizi omncane, izintambo ezilula nokufakwa okulula.

Indlela yokufaka yesibambisi sombani esikabili-kokukodwa:
1. ikhamera yenethiwekhi ikhamera ye-two-in-one isibambisi sombani sifakwe ochungechungeni phambi kwembobo yekhamera yenethiwekhi (itheminali yokuhlonza ethi "INPUT" ixhunywe kulayini, futhi itheminali yokuhlonza "OUTPUT" ixhunywe kukhamera evikelwe) , bese kuthi i-PE grounding terminal ishiselwe noma ibhowulwe kugridi yaphansi ngentambo yethusi ewumgogodla.
2. Indlela yokuxhumana yetheminali yentambo kagesi yekhamera yenethiwekhi yesibambisi sombani esikabili-kokukodwa: izingxenye ezimbili zamandla kagesi zixhunywe no-"L/+"kanye no-"N/-" ngokulandelanayo.
3. Ukuxhumeka komugqa wesignali yenethiwekhi ye-RJ45 yekhamera yenethiwekhi yesibambisi sombani ezimbili-in-one: ifakwe ochungechungeni, futhi ikhanda le-crystal le-RJ45 lixhunywe ngokuqondile.
4. Indawo ephambanayo yocingo oluphansi lokuvikela umbani kufanele ibe ≥2.5mm2 futhi ibe mfushane ngangokunokwenzeka. Ukufakwa kwalo mkhiqizo wokuvikela umbani kudinga ukuthi ukumelana nomhlaba kungaphansi kuka-4Ω, futhi ukusebenza kokuvikela umbani kuhamba phambili uma intambo yaphansi kanye nokumelana nomhlaba kufanelekile.
5. Lesi sici esibamba umbani asikhathaleli, futhi isimo sokusebenza sokuvala umbani kufanele sihlolwe futhi sirekhodwe kusenesikhathi ngemva kokuduma kwezulu.
1. Ngaphambi kokuthi intambo yesivikeli sokuhlinza ixhunywe kumpahla evikelwe, amandla kufanele avaliwe, futhi ukusebenza bukhoma kunqatshelwe ngokuphelele. .
2. Kufakwe ochungechungeni phakathi kwemigqa yezinto ezivikelwe, uxhumo lwesixhumi esibonakalayo kufanele luthembeke, futhi isivikeli sokuhlinza sinamamaki okufaka (IN) kanye nawokuphumayo (OUT). Itheminali yokuphumayo ixhunywe kumpahla evikelwe, ungaxhumeki ngokuhlehla. Uma kungenjalo, umvikeli ohlinzayo uzolimala lapho umbani ushaya, futhi okokusebenza ngeke kuvikelwe ngempumelelo (bheka umdwebo wokufaka kanye nezintambo).
3. Intambo yaphansi (PE) kufanele ixhunywe ngokuthembekile ocingweni lwaphansi lwesistimu yokuvikela ukukhuphuka, futhi ubude kufanele bube bufushane kakhulu ukuze kuzuzwe umphumela wokuvikela ongcono kakhulu.
4. Izinto zokusebenza kufanele zinqanyulwe lapho kufakwa ucingo oluphansi ukuze kugwenywe ukulimala kwemishini ngenxa yokwethulwa kwemisinga enamandla njenge-welding kagesi kusukela ekugcineni kocingo oluphansi.
5. Xhuma intambo yaphansi yesivikeli sokuhlinza kanye negobolondo lensimbi lezinto zokusebenza kubha yokuqoqa phansi.
6. Ngesikhathi sokusetshenziswa, umvikeli ohlinzayo kufanele ahlolwe njalo. Uma ihluleka, kufanele ilungiswe noma ishintshwe kusenesikhathi ukuze kuqinisekiswe ukuphepha kwempahla evikelwe.
7. Abangewona ochwepheshe akufanele bayihlakaze.
