Ikibazo cyo Guhitamo Ibikoresho Bifunga Amadirishya yo Gufunga Amadirishya

Ikibazo cya 1: Umugozi umwe wa MCB mu ruganda (Schneider iC65N)
Aho ibintu bibera: Amatara yo mu iduka/imiyoboro y'amatara, umukingo muto w'imiyoboro imwe, umukingo ufite umwobo usanzwe wo gufunga
Imashini igabanya urujya n'uruza rw'amashanyarazi: Schneider iC65N 1P C16
Amahitamo: Gufunga byagenewe Snap-on (nk'uko Schneider A9A26970 / Badi 65387)
Impamvu yo guhitamo:
Iyi snap-on yagenewe ijyanye neza n'umugozi wa iC65, ikarinda guhinda no gucika kw'imitsi
Nta bikoresho, kuyishyiraho vuba, amasegonda 10 kugira ngo umuntu umwe arangije kuyifunga
Ihuye n'ingufuri zisanzwe, ihuye n'ibisabwa na LOTO y'umuntu umwe
Ubwuzuzi: Bihuye na GB/T 14048.2, NFPA 70E, aho umuntu ahagarara hagaragara + aho afungira
Urugero rwa 2: Akabati ko gukwirakwiza ibirango bivanze (ibirango byinshi bya MCB)
Aho ibintu bibera: Icyumba cyo gukwirakwiza imitungo, harimo Schneider, Siemens, ZTE, n'ibindi. MCB zifite inkingi imwe
Imashini igabanya urujya n'uruza rw'amashanyarazi: Ubugari bw'umugozi ni mm 12–20, zimwe nta mwobo wo kuzifunga
Amahitamo: Ingufuri rusange ishobora guhindurwa yo gufungura uruziga (nk'iya BOZZYS D18 / Master 493B)
Impamvu yo guhitamo:
Ibipfukisho bishobora guhindurwa bifite imikandara ya 12–23mm, bihuye n'ibirango byinshi
Gufunga ibyuma bifunga, bikwiranye na MCB zifite cyangwa zidafite imyobo yo gufunga
Nylon y'ubuhanga + icyuma kidashonga, kirwanya ibizinga by'amavuta, kirwanya ingaruka
Gukurikiza amategeko: Bihuye na NEC 110.25, bikwiriye gukoreshwa mu guhitamo ubwoko buvanze bw'ibicuruzwa aho bikorera.
Igice cya 3: Urugendo rw'ingenzi rw'inganda rufite ibyiciro bitatu (icyuma cya pulasitiki MCCB)
Aho ibintu bibera: Umuyoboro mukuru wa moteri wa 37kW, Schneider NSX100N 3P
Imashini igabanya urujya n'uruza rw'amashanyarazi: Igikonoshwa cya pulasitiki gifite inkingi eshatu, ubugari bw'umukingo ni mm 25, nta mwobo usanzwe wo gufunga
Guhitamo: Guhuza lock y'ibiti bitatu (nk'iya Loko M-K24 / ETA X4230)
Impamvu yo guhitamo:
Guhuza umugozi w'inkingi eshatu n'umugozi, birinda kugwa ku bw'impanuka
Imbaraga nini zo gufunga zikwiriye umugozi uremereye wa MCCB, zikarinda gufungura ku buryo butunguranye
Ishyigikira uburyo bwo gufunga abantu benshi, ikubahiriza ibisabwa na LOTO yo kubungabunga itsinda
Ubwuzuzi: Ikurikiza IEC 60947-3, ikwiriye insinga z'inganda zikoresha ingufu nyinshi
Agasanduku ka 4: Imashini ikoresha amashanyarazi ya pulasitiki idafite imyobo (ABB Tmax)
Aho ibintu bibera: Akabati ko gukwirakwizamo ibintu mu gice cy'ibinyabutabire, ABB Tmax T1N 3P, umukingo udafite umwobo wo gufunga, n'umwanya muto
Imashini igabanya urujya n'uruza rw'amashanyarazi: Nta mwobo wo gufunga, ingendo ngufi
Guhitamo: Ingufuri yo gufunga idafite imyobo (nk'iya Badi 65680 / Master 495)
Impamvu yo guhitamo:
Gufunga byuzuye, bidashingiye ku mwobo wo gufunga, bikwiriye gukoreshwa muri MCCB yihariye
Igishushanyo mbonera gito cyane, gikwiriye amakabati yo gukwirakwizamo ibintu byinshi
Inyubako irwanya itora, yujuje ibisabwa ku buziranenge bw'ahantu hakoreshwa imiti
Iyubahirizwa: Yujuje ibisabwa na ATEX mu kwirinda guturika, ikwiriye ibyuma byihariye byabugenewe byo gukata uruziga
Agasanduku ka 5: Akabati k'icyumba cyo gukwirakwizamo ibintu (agace kagabanya urujya n'uruza rw'ibintu)
Aho ibintu bibera: 1000A universal circuit breaker (DW45), kubungabunga akabati kose
Akamashini gakoresha uruziga: Urugi rw'akabati rushobora gukingurwa mu bwoko bwa kabati / Agasanduku gafite imiterere ihamye
Amahitamo: Ingufuri y'urugi rw'akabati + ifunguzo ry'umubiri w'imashini igabanya urujya n'uruza rw'amashanyarazi ifite imfunguzo ebyiri
Impamvu yo guhitamo:
Ingufuri y'ibice ifunga urugi rw'akabati, ikabuza abakozi batabifitiye uburenganzira kwinjira
Gufunga umubiri hakoreshejwe imfunguzo ebyiri, bisaba imfunguzo ebyiri kugira ngo ukingure, kugenzura abantu babiri
Uburinzi bw'urwego rwinshi, buhuye n'ibipimo bya LOTO byo mu cyumba cyo gukwirakwizamo ibintu bifite ibyago byinshi
Iyubahirizwa: Yujuje amabwiriza y'umutekano mu nganda z'amashanyarazi, ikwiriye imiyoboro migari yinjiye/iy'ingenzi ya transfoma
Igice cya 6: Gukorera hamwe (gufunga icyarimwe imiyoboro myinshi)
Aho ibintu bibera: Gusana ibikoresho 10 icyarimwe, abantu benshi bakora
Circuit breaker: MCB nyinshi imwe / eshatu zifite inkingi imwe + MCCB zivanze
Guhitamo: Udukingirizo twinshi two gufunga + agasanduku k'ingufuri rusange + utwo gufunga twihariye ku ruziga
Impamvu yo guhitamo:
Buri ruziga rufunze ku giti cyarwo hakoreshejwe ifunga ryarwo
Udukingirizo twinshi dushyigikira gufunga urukiramende rumwe icyarimwe n'abantu benshi
Agasanduku k'imfunguzo gacunga imfunguzo mu buryo bumwe, gufungura bisaba kwemeza abakozi bose
Iyubahirizwa ry'amategeko: Yujuje ibisabwa na OSHA 1910.147, yujuje ibisabwa na LOTO mu bufatanye
