Iyo ushyizeho imirasire y'izuba, insinga nziza ni ngombwa cyane. Bafasha kurinda sisitemu umutekano no gukora neza. UL4703 insinga zizuba nuburyo bwizewe bwo gushiraho izuba. Yakozwe kugirango yujuje ubuziranenge bwo hejuru kandi imara igihe kirekire. Izi nsinga zirashobora gukoresha ubushyuhe, ibihe bibi, kandi bigakora neza. Ibi bituma bagomba-kugira imishinga igezweho yizuba, nkibisenge hejuru yinzu cyangwa imirima minini yizuba.
Ibyingenzi
- UL4703 insinga zizuba zikoresha ingufu nyinshi zumuriro wizuba. Ibi bifasha ingufu kugenda neza kandi bizamura imikorere ya sisitemu.
- Umugozi ukora mubihe bishyushye cyangwa bikonje cyane, kuva -40 ° F kugeza + 248 ° F. Ibi bituma bigira akamaro mubihe byinshi bitandukanye.
- Igishushanyo cyacyo kigoramye cyorohereza gushiraho, ndetse no mumwanya muto. Ibi bizigama umwanya kandi bigabanya amahirwe yo kwangirika mugihe cyo kwishyiriraho.
- Gutora insinga zemewe na UL nka UL4703 zujuje amategeko yumutekano. Igabanya ingaruka zumuriro kandi igenzura byoroshye.
- UL4703 insinga zizuba zigura byinshi mbere ariko uzigama amafaranga nyuma. Igabanya gusana no kunoza uburyo ingufu zitemba neza.
Ibidasanzwe bya UL4703 Imirasire y'izuba
Umuvuduko mwinshi wa voltage kubikorwa byizewe
Imirasire y'izuba, ubushobozi bwa voltage ni ngombwa cyane. Ifasha sisitemu gukora neza no gukomeza kwizerwa. UL4703 insinga zizuba zidasanzwe kuko ikora voltage nyinshi. Ikorana na 600-1000VAC na 2000VDC, bivuze ko ishobora gucunga imitwaro minini y'amashanyarazi neza. Izi nsinga zapimwe kuri 6500V muminota 10 kugirango zerekane imbaraga zazo.
- Inyungu zo hejuru ya voltage nyinshi:
- Ingufu nziza zitemba no gukoresha.
- Gukoresha neza amashanyarazi akomoka ku mirasire y'izuba.
- Imikorere ikomeye kumazu no mubucuruzi.
Iyi mikorere ituma izuba ryizuba rihoraho kandi neza. Haba hejuru y'inzu cyangwa umurima munini w'izuba, insinga ya UL4703 ikora akazi neza.
Kurwanya Ubushyuhe budasanzwe
Imirasire y'izuba ihura nikirere gikaze, kuva izuba ryinshi kugeza imbeho ikonje. UL4703 insinga zizuba zubatswe kugirango zikemure izo ntagondwa. Ikora mu bushyuhe kuva kuri -40 ° C kugeza kuri + 120 ° C. Mumuzunguruko mugufi, irashobora gukora kugeza kuri + 250 ° C kumasegonda 5.
| Ibisobanuro | Agaciro |
|---|---|
| Icyiza. ubushyuhe bwibidukikije | + 120 ° C. |
| Min. ubushyuhe bwakazi | -40 ° C. |
| Icyiza. ubushyuhe bwuyobora | + 120 ° C. |
| Icyiza. ubushyuhe buke | + 250 ° C (max 5s) |
| UL 4703 igipimo cy'ubushyuhe | 90 ° C itose / yumye |
| Ibipimo by'inyongera | 105 ° C, 125 ° C, 150 ° C yumye |
Igishushanyo cyoroshye cyo kwishyiriraho byoroshye
Gushiraho insinga zizuba birashobora kuba ingorabahizi, cyane cyane ahantu hafatanye. UL4703 insinga yizuba yorohereza nigishushanyo cyayo cyoroshye. Yunamye byoroshye ariko ikomeza gukomera. Bitandukanye ninsinga zisanzwe za USE-2, UL4703 ikozwe mumirasire y'izuba kandi ikora neza.
| Ikiranga | UL4703 Imirasire y'izuba | Imirasire y'izuba isanzwe (USE-2) |
|---|---|---|
| Guhinduka | Buri gihe byoroshye | Ntabwo bose bapimwe kugirango bahinduke |
| Gusaba muri array | Irashobora gukoreshwa muburyo budafite aho bugarukira | Gusa kuri sisitemu ishingiye |
| Ikigereranyo cya Gauge | Kuboneka mubipimo bito | Guhera kuri 14 AWG |
Ihinduka ritwara igihe kandi rikirinda kwangirika mugihe cyo gushiraho. Haba ku gisenge cyangwa ku zuba rireremba, insinga ya UL4703 ihuye nibyo ukeneye kandi ikora byoroshye.
Umutekano no kubahiriza UL Yemerewe izuba
Kuki ibyemezo bya UL bifite akamaro mumirasire y'izuba
Icyemezo cya UL ni urufunguzo rwo kurinda imirasire y'izuba umutekano kandi wizewe. Gutora insinga zemewe za UL bivuze ko zujuje amategeko akomeye yumutekano. Izi nsinga zinyura mubizamini bikomeye, kuburyo zishobora gukoreshwa ako kanya. Ibi bituma ama code yinyubako yoroshye kandi byihuta kugenzura.
UL Intsinga izwi nayo irafasha. Bageragejwe kubintu bimwe kandi bakorana neza nibindi bice. Mugihe gifite umutekano, bakeneye cheque yinyongera kugirango yemeze sisitemu yuzuye.
Ibipimo byingenzi nkaUL 4703na IEC 62930 reba imbaraga z'amashanyarazi, igihe kirekire, n'umutekano wumuriro. Gukurikiza aya mategeko bituma sisitemu yizuba itekanye kandi ikayifasha gutsinda ubugenzuzi byoroshye.
Inama: Buri gihe hitamo insinga zemewe za UL kumishinga yizuba. Zujuje amategeko yumutekano agezweho hamwe na code yamashanyarazi.
Umutekano wumuriro nubuziranenge bwamashanyarazi
Umutekano wumuriro ni ingenzi cyane muri sisitemu yizuba. Intsinga zemewe za UL zitsinda ibizamini byumuriro n’amashanyarazi kugirango bigabanye ingaruka. Kurugero,UL 4703kugenzura niba insinga zishobora gukoresha urumuri rwizuba, ubushyuhe, nikirere kibi.UL 1581igerageza uburyo umuriro ukwirakwira kuri wire.
| Bisanzwe | Ikigeragezo |
|---|---|
| UL 4703 | Koresha urumuri rw'izuba, ubushyuhe, nikirere. |
| UL 1581 | Kugenzura ibirimi by'umuriro bikwirakwizwa ku bice by'insinga. |
Ibi bizamini byerekana ko insinga zemewe za UL zishobora gukemura ibibazo bikomeye. Gukoresha izo nsinga bigabanya ingaruka zumuriro kandi bigatuma sisitemu yizuba irushaho kwizerwa.
Gukurikiza amategeko y’amashanyarazi (NEC)
Imirasire y'izuba igomba gukurikiza amategeko agenga amashanyarazi (NEC). UL yemewe ya UL ihuye namategeko ya NEC, ikora neza kandi neza. Ibipimo nkaUL 4703na NFPA 70 bashiraho amategeko yo gukumira, umutekano wumuriro, nubushyuhe bwubushyuhe.
| Bisanzwe | Icyo Itwikiriye |
|---|---|
| UL-4703 | Yujuje amategeko ya UL kumashanyarazi yizuba. |
| NFPA 70 | Kurikiza NEC kugirango ushyireho umutekano. |
Izi mpamyabumenyi zemeza ko insinga zirwanya izuba, ubushuhe, kandi bigakorera ahantu hatose, hashyushye. Ukurikije NEC, sisitemu yizuba yawe irinda umutekano kandi ikora neza kumyaka.
Inyungu zifatika za UL4703 Photovoltaic Wire
Kuramba kuramba mubihe bikomeye
Imirasire y'izuba ikenera insinga zikomeye kugirango zimare igihe kirekire. UL4703 insinga ya Photovoltaque ikorwa kugirango ikirere gikemuke. Ikoresha umuringa usizwe hamwe na insulation idasanzwe kugirango ikomeze gukomera. Ibi bikoresho bifunga imirasire ya UV, amazi, nubushyuhe bukabije cyangwa ubukonje. Ibi bituma insinga zikora neza imyaka myinshi. Haba mubutayu cyangwa hafi yinyanja, izi nsinga zirashobora gukemura byose.
