Ni iki gisobanura IEC 61643-11 Type 1 SPD?

Dukurikije ibivugwa na IEC 61643-11 Ubwoko bwa 1 SPD ibi bikoresho bigomba kwihanganira Ubwiyongere bw'umuraba wa 10/350 µs, biganisha ku muvuduko w'inkuba ikubita mu buryo butaziguye.

Bitandukanye n'ibikoresho byo kurinda biri inyuma y'amazi, Ubwoko bwa 1 bw'igikoresho cyo kurinda umuvuduko SPD ishyirwa ku muryango wa serivisi cyangwa ku kibaho gikuru cyo gukwirakwiza ibicuruzwa kugira ngo ibe urwego rwa mbere rw'ubwirinzi mu buryo bwuzuye sisitemu yo guhuza uburyo bwo kurinda umuvuduko.

Mu buryo bugezweho bw'ingufu z'inganda, icyuma gikingira inkuba yemeza ko imirasire y'amashanyarazi ijyanwa hasi mu mutekano mbere yuko ikwirakwira cyane mu muyoboro w'amashanyarazi.

Ibisubizo by'inganda byo kurinda abinjira biboneka mu buryo bw'umwuga sisitemu zo kurinda umuvuduko w'amazi ikoreshwa mu bikorwa remezo, inganda zikora, n'ibigo by'ingufu zisubira.

Ni gute SPD zo mu bwoko bwa 1 zirinda amapaneri yo kwinjira muri serivisi?

A icyuma gikingira kwinjira kwa serivisi ikora binyuze mu kuyobya imirasire y'amashanyarazi iva ku murongo w'amashanyarazi ijya ku gice cyo hasi.

Ibi bikoresho byakozwe mu buryo bwihariye kugira ngo bihangane n'ingufu nyinshi ziterwa n'umuvuduko Ubwirinzi bw'ingufu za 10/350 µs ikizamini gisabwa hakurikijwe amabwiriza ya IEC.

Uburyo bwo gusohora umuriro w'amashanyarazi

Iyo inkuba ikubise umuyoboro w'amashanyarazi cyangwa inyubako iri hafi aho, imiyoboro minini y'amashanyarazi ishobora kwinjira mu ishyirwaho ry'amashanyarazi.

Itsinda icyuma kirinda umuyaga w'amashanyarazi ikora ibice by'imbere birinda umuntu nka:

• icyuho cy'ibishashi

• imiyoboro isohora umwuka (GDT)

• Varisitori z'icyuma zikora cyane (MOV)

Ibi bice bitwara ingufu ziturutse ku butaka, bikarinda ko ingufu zirenze urugero zangiza ibikoresho biri munsi y'amazi.

A igikoresho cyo kurinda umuvuduko w'amazi ku gice cy'ingenzi bityo ikaba ikora nk'icyiciro cya mbere cya Ubwoko bwa 1 Ubwoko bwa 2 Ubwoko bwa 3 SPD hirindwa, kugenzura ko ingufu z'amashanyarazi zigabanuka buhoro buhoro mu buryo bwose.

Ibiranga tekiniki bisanzwe bya SPD yo mu bwoko bwa 1

Ibi Ibikoresho byo kurinda isuri ya Iimp ni ingenzi cyane ku bikoresho bifite uburyo bwo kurinda inkuba zo hanze cyangwa biri mu turere twinshi tw’inkuba.

Ku bikoresho bihuza amashanyarazi n'uburinzi bw'imirasire mu gice kimwe, injeniyeri zikunze gukoresha Ibikoresho byo kurinda indwara zo mu bwoko bwa 1+2.

Ni hehe DIN Rail Type 1 Surge Protectors ikoreshwa?

A Ubwirinzi bw'umuraba wa DIN wo mu bwoko bwa 1 yagenewe gushyirwa mu bikoresho by'amashanyarazi hakoreshejwe uburyo busanzwe bwo gushyiraho imiyoboro ya DIN.

Iyi configuration yemerera koroshya guhuza switchboards z'inganda n'amabati y'amashanyarazi.

Porogaramu Zisanzwe

Imiterere isanzwe irimo:

• sisitemu zo gukwirakwiza ingufu z'amashanyarazi mu nganda

• inyubako z'ubucuruzi zikoresha switchboards

• ibigo by'amakuru n'ibikorwaremezo by'itumanaho

• sisitemu z'ingufu za photovoltaic

• ibikorwa remezo by'ubwikorezi

Ibi bidukikije bisaba ko byizewe kurinda inkuba mu nganda kugira ngo hirindwe igihe cyo kubura akazi no kwangirika kw'ibikoresho.

Igishushanyo cyakozwe neza igikoresho cyo kurinda inkuba yemeza ko imirasire y'amashanyarazi ihuzwa neza mbere yuko igera ku bikoresho by'amashanyarazi byoroheje.

Mu gushushanya ikoranabuhanga rifatika, ibi bikoresho bikora hamwe n'ibikoresho birinda biri munsi y'amazi nk'igice cya sisitemu yo guhuza uburyo bwo kurinda umuvuduko.

Nigute wakwizeza ko ubwoko bwa 1 SPD buhuye na sisitemu za TN-S cyangwa TT?

Guhitamo neza SPD bigomba gusuzuma imiterere ya sisitemu yo gusimbuza.

Imiterere itandukanye yo gucukura itaka isaba insinga zitandukanye za SPD kugira ngo habeho ko umuriro usohoka mu buryo butekanye.

Sisitemu Isanzwe yo Gutunganya Itaka

Ibyuma byinshi bikoresha amashanyarazi bikoresha imwe muri izi zikurikira:

• Sisitemu ya TN-S

• Sisitemu ya TT

Byombi bisaba uburyo bwihariye bwo guhuza SPD kugira ngo hakomeze kubaho imikorere myiza yo gufunga ubutaka.

Imiterere ya SPD kuri sisitemu zitandukanye zo gukwirakwiza ubutaka

Guhitamo uburyo bujyanye Uburinzi bw'ingufu zo gushonga kw'ubutaka bwa TN-S TT imiterere y'amashanyarazi igenzura ko umuriro w'amashanyarazi usohoka mu mutekano nta kibazo gihari mu gushyiraho.

Abahanga mu gushushanya uburyo bwo kurinda inkuba bakunze kwita ku buryo bw'umwuga bwo gushyiraho ibikoresho nk'ibi Ubwoko bwa 1 SPD Ubuyobozi bwo gushyiraho kugira ngo harebwe ko sisitemu ihuzwa neza.

Umwanzuro

A Ubwirinzi bw'ubwiyongere bw'umuvuduko wo mu bwoko bwa 1 bigira uruhare runini mu kurinda amashanyarazi imirasire y'amashanyarazi yinjira mu nsinga z'amashanyarazi.

Nk'uko byasobanuwe na IEC 61643-11 Ubwoko bwa 1 SPD, ibi bikoresho bigomba kwihanganira imirasire y'ingufu nyinshi igaragazwa n'imirasire Ubwiyongere bw'umuraba wa 10/350 µs.

Iyo bishyizwe ku muryango wa serivisi cyangwa ku kibaho gikuru gitanga serivisi, Ubwoko bwa 1 bw'igikoresho cyo kurinda umuvuduko SPD inzego zikora nk'icyiciro cya mbere cy'ingamba zo kurinda zihujwe, zigashyiraho ishingiro ry'uburyo bwizewe Ubwoko bwa 1 Ubwoko bwa 2 Ubwoko bwa 3 SPD hirindwa ubwubatsi.

Mu kwemeza ko bihuye na Uburinzi bw'ingufu zo gushonga kw'ubutaka bwa TN-S TT sisitemu no kuzishyira muri sisitemu yuzuye yo guhuza uburyo bwo kurinda umuvuduko w'amashanyarazi, injeniyeri zishobora kurinda neza ibikorwa remezo by'amashanyarazi by'inganda.

Ibibazo Bikunze Kubazwa

Ikirinda indwara yo mu bwoko bwa 1 surge ni iki?

Ikirinda gushyuha k'ubwoko bwa 1 ni igikoresho gikingira gushyuha cyagenewe gusohora imirasire y'amashanyarazi ifite ingufu nyinshi yinjira mu imashini ikoresha amashanyarazi inyuze mu muyoboro w'amashanyarazi.

Ni iyihe miterere y'umuraba ikoreshwa mu gupima SPD zo mu bwoko bwa 1?

SPD zo mu bwoko bwa 1 zipimwa hakoreshejwe uburyo bwa 10/350 µs imirabyo y'imirabyo, biganisha ku muvuduko w'inkuba ikubita mu buryo butaziguye.

Igikoresho cyo kurinda indwara yo mu bwoko bwa 1 surge gikwiye gushyirwa he?

Ubusanzwe ishyirwa ku muryango wa serivisi cyangwa ku kibaho gikuru cyo gukwirakwiza kugira ngo itange uburinzi bw'ibanze ku nkuba.

Igipimo cya Iimp muri SPD yo mu bwoko bwa 1 ni ikihe?

Itsinda Isuzuma rya Iimp isobanura ubushobozi bwo gukuraho ingufu za SPD yo mu bwoko bwa 1 munsi y’ishusho y’umuraba wa 10/350 µs.

Ese ubwoko bwa 1 SPD bushobora gukoreshwa muri sisitemu za TN-S cyangwa TT earthing?

Yego. SPD zo mu bwoko bwa 1 zagenewe guhuza na sisitemu zo gukwirakwiza TN-S na TT iyo hakoreshejwe imiterere ikwiye y'insinga.
