Akamaro k'ubwoko B RCDs mumashanyarazi agezweho: Kurinda umutekano mumashanyarazi ya AC na DC

Andika B Ibikoresho bigezweho (RCDs)ni ibikoresho byihariye byumutekano bifasha gukumira amashanyarazi n’umuriro muri sisitemu zikoresha amashanyarazi ataziguye (DC) cyangwa zifite amashanyarazi adasanzwe. Bitandukanye na RCD isanzwe ikorana nubundi buryo bwo guhinduranya (AC), Ubwoko B RCDs irashobora gutahura no guhagarika amakosa mumirongo yombi ya AC na DC. Ibi bituma bakora cyane mumashanyarazi mashya nka sitasiyo yumuriro wamashanyarazi, imirasire yizuba, turbine yumuyaga, nibindi bikoresho bikoresha ingufu za DC cyangwa bifite amashanyarazi adasanzwe.

Ubwoko B RCDs butanga uburinzi numutekano muri sisitemu zigezweho zamashanyarazi aho DC hamwe numuraba udasanzwe. Byaremewe guhita bihagarika amashanyarazi mugihe bumva ubusumbane cyangwa amakosa, birinda ibintu bishobora guteza akaga. Mugihe icyifuzo cya sisitemu y’ingufu zishobora kongera ingufu n’imodoka zikoresha amashanyarazi zikomeje kwiyongera, Ubwoko B RCDs bwabaye ngombwa mu kurinda umutekano w’ikoranabuhanga rishya. Zifasha gukumira amashanyarazi, umuriro, no kwangiza ibikoresho byoroshye mugushakisha vuba no guhagarika amakosa yose mumashanyarazi. Muri rusange, Ubwoko B RCDs niterambere ryingenzi mumutekano wamashanyarazi, rifasha kurinda abantu numutungo umutekano mwisi hamwe no gukoresha ingufu za DC hamwe n’umuriro w'amashanyarazi udasanzwe.

Ibiranga JCRB2-100 Ubwoko B RCDs

Ubwoko bwa JCRB2-100 Ubwoko B RCDs nibikoresho byumutekano byamashanyarazi bigezweho bigamije kurinda byimazeyo amakosa atandukanye muri sisitemu yamashanyarazi agezweho. Ibyingenzi byabo byingenzi birimo:

Kugenda Kumva: 30mA

Kugenda gukabije kwa 30mA kuri JCRB2-100 Ubwoko B RCDs bivuze ko igikoresho kizahita gihagarika amashanyarazi niba kibonye amashanyarazi yamenetse ya 30 milliamps (mA) cyangwa arenga. Uru rwego rwo kwiyumvisha ibintu ni ingenzi cyane kugirango harebwe urwego rwo hejuru rwo kwirinda impanuka zishobora gukomoka ku mashanyarazi cyangwa umuriro uterwa n’amakosa y’ubutaka cyangwa imigezi yatemba. Imiyoboro yamenetse ya 30mA cyangwa irenga irashobora guteza akaga gakomeye, ishobora guteza imvune zikomeye cyangwa n’urupfu iyo itagenzuwe. Mugukandagira kururu rwego rwo hasi rwo kumeneka, JCRB2-100 ifasha mukurinda ibintu nkibi bishobora kubaho, guhagarika amashanyarazi vuba mbere yuko ikosa rishobora guteza ingaruka.

2-Inkingi / Icyiciro kimwe

JCRB2-100 Ubwoko B RCDs zakozwe nkibikoresho 2-pole, bivuze ko bigenewe gukoreshwa muri sisitemu y'amashanyarazi icyiciro kimwe. Sisitemu yicyiciro kimwe iboneka mumazu yo guturamo, mu biro bito, no mu nyubako zubucuruzi zoroheje. Muriyi miterere, imbaraga zicyiciro kimwe zikoreshwa muburyo bwo gucana amatara, ibikoresho, nibindi bito bito byamashanyarazi. Ibice 2 bya pole ya JCRB2-100 ituma ikurikirana kandi ikarinda imiyoboro nzima kandi itabogamye mu cyiciro kimwe, ikarinda umutekano wuzuye amakosa ashobora kugaragara kumurongo umwe. Ibi bituma igikoresho gikwiranye no kurinda icyiciro kimwe gusa, cyiganje mubidukikije byinshi bya buri munsi.

Igipimo kiriho: 63A

Ubwoko bwa JCRB2-100 Ubwoko B RCDs bufite igipimo cya 63 amps (A). Uru rutonde rwerekana umubare ntarengwa w'amashanyarazi igikoresho gishobora gukora neza mugihe gisanzwe gikora nta gutembera cyangwa kurenza urugero. Muyandi magambo, JCRB2-100 irashobora gukoreshwa mukurinda imashanyarazi ifite imitwaro igera kuri 63 amps. Uru rutonde rugezweho rutuma igikoresho gikwiranye nubucuruzi butandukanye bwo guturamo no koroshya ubucuruzi, aho imizigo yamashanyarazi isanzwe igwa muriki cyiciro. Icyakora, ni ngombwa kumenya ko nubwo ikigezweho kiri mu gipimo cya 63A, JCRB2-100 izakomeza kugenda iyo ibonye imiyoboro yamenetse ya 30mA cyangwa irenga, kuko uru arirwo rwego rwo gukenera gukingira amakosa.

Ikigereranyo cya voltage: 230V AC

JCRB2-100 Ubwoko B RCDs ifite voltage ya 230V AC. Ibi bivuze ko bagenewe gukoreshwa muri sisitemu y'amashanyarazi ikorera kuri voltage nominal ya 230 volt ihinduranya amashanyarazi (AC). Urutonde rwa voltage rusanzwe mubikorwa byinshi byo guturamo nu mucyo ubucuruzi, bigatuma JCRB2-100 ibereye gukoreshwa muribi bidukikije. Ni ngombwa kumenya ko igikoresho kitagomba gukoreshwa muri sisitemu y’amashanyarazi hamwe n’umuvuduko urenze umuvuduko wacyo, kuko ibyo bishobora kwangiza igikoresho cyangwa kubangamira ubushobozi bwo gukora neza. Mugukurikiza igipimo cya voltage ya 230V AC, abakoresha barashobora kwemeza ko JCRB2-100 izakora neza kandi neza mumashanyarazi yagenewe.

Ubushobozi Bugufi-Inzira Ubushobozi: 10kA

Ubushobozi buke bwumurongo wa JCRB2-100 Ubwoko B RCDs ni kiloamps 10 (kA). Uru rutonde rwerekana umubare ntarengwa wigihe gito cyumuzunguruko igikoresho gishobora kwihanganira mbere gishobora kwangirika cyangwa kunanirwa. Imiyoboro ngufi irashobora kugaragara muri sisitemu y'amashanyarazi kubera amakosa cyangwa ibihe bidasanzwe, kandi birashobora kuba hejuru cyane kandi birashobora gusenya. Mugihe ufite imiyoboro ngufi ya 10kA, JCRB2-100 yashizweho kugirango ikomeze gukora kandi itange uburinzi kabone niyo haba hari ikibazo gikomeye cyumuzunguruko, kugeza kuri amps 10,000. Iyi mikorere iremeza ko igikoresho gishobora kurinda neza sisitemu yamashanyarazi nibiyigize mugihe habaye amakosa nkaya-agezweho.

Urutonde rwa IP20

Ubwoko bwa JCRB2-100 B RCDs bufite igipimo cyo kurinda IP20, gisobanura igipimo cya “Ingress Protection” 20.Icyiciro cyerekana ko igikoresho kirinzwe ku bintu bikomeye bifite milimetero 12,5 z'ubunini, nk'intoki cyangwa ibikoresho. Ariko, ntabwo irinda amazi cyangwa andi mazi. Nkigisubizo, JCRB2-100 ntabwo ikwiriye gukoreshwa hanze cyangwa kuyishyira ahantu hashobora guhura nubushuhe cyangwa amazi bitarinze kurindwa. Kugira ngo ukoreshe igikoresho hanze cyangwa ahantu hatose, bigomba gushyirwaho imbere yikigo gikubiyemo uburinzi bukenewe bwo kwirinda amazi, ivumbi, nibindi bintu bidukikije.

Kubahiriza IEC / EN 62423 na IEC / EN 61008-1 Ibipimo

Ubwoko bwa JCRB2-100 B RCDs yateguwe kandi ikorwa hubahirijwe amahame abiri yingenzi mpuzamahanga: IEC / EN 62423 na IEC / EN 61008-1. Ibipimo ngenderwaho bisobanura ibisabwa nibipimo ngenderwaho kubikoresho bisigaye bigezweho (RCDs) bikoreshwa mumashanyarazi make. Kubahiriza aya mahame byemeza ko JCRB2-100 yujuje umutekano, imikorere, nubuyobozi bwiza, byemeza urwego ruhoraho rwo kurinda no kwizerwa. Mugukurikiza aya mahame azwi cyane, abayikoresha barashobora kwizera mubushobozi bwigikoresho cyo gukora nkuko byateganijwe kandi bagatanga uburyo bukenewe bwo kwirinda amakosa y’amashanyarazi n’ibyago.

Umwanzuro

UwitekaJCRB2-100 Ubwoko B RCDsnibikoresho byumutekano bigezweho bigamije gutanga uburinzi bwuzuye muri sisitemu yamashanyarazi agezweho. Hamwe nibintu bimeze nka 30mA yikurikiranya cyane, bikwiranye nibisabwa icyiciro kimwe, igipimo cya 63A, hamwe na 230V ya voltage ya AC, batanga uburyo bwizewe bwo kwirinda amakosa yumuriro. Byongeye kandi, ubushobozi bwabo bwa 10kA bugufi bwumuzunguruko, igipimo cyo kurinda IP20 (gisaba uruzitiro rukwiye rwo gukoreshwa hanze), no kubahiriza ibipimo bya IEC / EN byemeza imikorere ikomeye no kubahiriza amabwiriza yinganda. Muri rusange, JCRB2-100 Ubwoko B RCDs itanga umutekano wizewe kandi wizewe, bigatuma iba ikintu cyingenzi mumashanyarazi atuye, yubucuruzi, ninganda.

Ibibazo

1.Ubwoko B RCD ni ubuhe?

Ubwoko B RCDs ntigomba kwitiranwa nubwoko B MCBs cyangwa RCBOs zigaragara mubushakashatsi bwinshi bwurubuga.

Ubwoko B RCDs ziratandukanye rwose, ariko, ikibabaje nuko inyuguti imwe yakoreshejwe ishobora kuyobya. Hariho Ubwoko B aribwo bushyushye buranga MCB / RCBO na B B bisobanura ibiranga magnetiki muri RCCB / RCD. Ibi bivuze ko rero uzasangamo ibicuruzwa nka RCBOs biranga ibintu bibiri, aribyo bintu bya magnetiki ya RCBO hamwe nubushyuhe bwumuriro (ibi bishobora kuba Ubwoko bwa AC cyangwa Magnetique na Type B cyangwa C ubushyuhe bwa RCBO).

2.Nigute Ubwoko B RCDs bukora?

Ubwoko B RCDs busanzwe bukorwa hamwe na sisitemu ebyiri zisigaye zo gutahura. Iya mbere ikoresha tekinoroji ya 'fluxgate' kugirango RCD ibashe kumenya neza DC igezweho. Iya kabiri ikoresha tekinoroji isa na Type AC na Type A RCDs, ni voltage yigenga.
