Niki Kumena Isi Yumuzenguruko (ELCB) & Igikorwa cyayo

Kumeneka kwisi kwangirika kumashanyarazi ni ibikoresho byerekana voltage, ubu byahinduwe nibikoresho byumva (RCD / RCCB). Mubisanzwe, ibikoresho byunvikana byitwa RCCB, hamwe nibikoresho byerekana imbaraga za voltage bita Earth Leakage Circuit Breaker (ELCB). Imyaka mirongo ine irashize, ECLB yambere yambere yatangijwe kandi hashize imyaka nka mirongo itandatu ishize voltage ya mbere ECLB yatangijwe. Kumyaka itari mike, byombi voltage nubu ikora ELCBs byombi byiswe ELCBs kubera izina ryabo ryoroshye kwibuka. Ariko ikoreshwa ryibi bikoresho byombi ryahaye iterambere kuvanga cyane munganda zamashanyarazi.

Ni ubuhe buryo bwo kumena isi (ELCB)?

ECLB ni ubwoko bumwe bwibikoresho byumutekano bikoreshwa mugushiraho ibikoresho byamashanyarazi hamwe nubutaka bukabije kugirango wirinde guhungabana. Ibi bikoresho byerekana imbaraga ntoya zayobye zicyuma cyamashanyarazi kumurongo wibyuma kandi byinjira mukuzunguruka niba hagaragaye voltage iteje akaga. Intego nyamukuru ya Earth leakage circuit breaker (ECLB) nuguhagarika kwangirika kwabantu ninyamaswa kubera amashanyarazi.

ELCB ni ubwoko bwihariye bwo kwifata bufite imiterere yingufu zinjira zinjira zijyanye no guhinduranya kugirango uhinduranya umuzunguruko utandukanya ingufu mumutekano muke. ELCB ibona amakosa yimyitwarire yabantu cyangwa inyamaswa kumurongo wisi muburyo irinda. Niba voltage ihagije isa nkaho ELCB yunvikana, bizimya ingufu, kandi bigumeho kugeza igihe byongeye gutunganywa. Umuvuduko ukabije wa ELCB ntushobora kumenya inzira zituruka kumuntu cyangwa ku nyamaswa kugeza ku isi.

ELCB ibona imigendekere yimikorere yabantu cyangwa inyamaswa kumurongo wisi muburyo irinda. Niba voltage ihagije isa nkaho ELCB yunvikana, bizimya ingufu, kandi bigumeho kugeza igihe byongeye gutunganywa. Umuvuduko ukabije wa ELCB ntushobora kumenya inzira zituruka kumuntu cyangwa ku nyamaswa kugeza ku isi.

Imikorere ya ELCB

Igikorwa nyamukuru cyumuzunguruko wisi cyangwa ELCB nugukumira ihungabana mugihe amashanyarazi akoresheje isi ndende cyane kuko nigikoresho cyumutekano. Ivunika ryumuzunguruko ryerekana imbaraga ntoya zayobye hejuru yibikoresho byamashanyarazi hamwe nicyuma kandi bigahagarika uruziga niba hagaragaye ingufu za voltage. Intego nyamukuru ya ELCBs ni ukwirinda kugirira nabi abantu kimwe ninyamaswa kubera amashanyarazi.

Imikorere ya ELCB
Imashanyarazi yamashanyarazi nubwoko bwihariye bwo gufunga kandi ifite imiyoboro nyamukuru yinyubako zahujwe muguhuza kwayo kugirango iyi mashanyarazi izimya amashanyarazi namara kumenyekana kwisi. Ukoresheje ibi, ikosa ryikosa rirashobora kugaragara kuva mubuzima kugeza kumurongo wubutaka muburyo bukwiye. Niba voltage ihagije isohotse hejuru yunvikana coil yamashanyarazi, noneho izahagarika ingufu & igumeho kugeza igihe cyo gusubira kumubiri. ELCB ikoreshwa muri voltage-sensing ntishobora kumenya amakosa yimikorere.

Nigute ushobora guhuza isi yameneka

Umuzunguruko w'isi uhujwe iyo hakoreshejwe ELCB; ihuriro ryinkoni yisi ryemerwa binyuze mumatembabuzi yameneka yisi ahuza nubutaka bwayo bubiri. Imwe ijya kumuyoboro ukwirakwiza isi ikingira (CPC), indi igana inkoni yisi cyangwa ubundi bwoko bwisi. Gutyo, umuzunguruko w'isi wemerera binyuze muri coil ya ELCB.

Ibyiza bya voltage ikoreshwa na ELCB

ELCBs ntabwo yunvikana kumiterere yamakosa kandi ifite ingendo nke.
Mugihe umuyagankuba na voltage kumurongo wubutaka muri rusange bitesha umurongo uva mu nsinga nzima, ibi ntabwo bikomeza kubaho, kubwibyo rero hari ibihe aho ELCB ishobora gutesha urugendo.
Iyo kwishyiriraho ibikoresho byamashanyarazi bifite aho bihurira nisi, igitero cyegereye cyane cyumurabyo kizashinga imizi ya voltage gradient kwisi, gitanga icyuma cya ELCB cyunvikana hamwe na voltage ihagije kugirango gitange urugendo.
Niba imwe mu nsinga zubutaka zitandukanijwe na ELCB, ntizongera kwishyiriraho ntizizongera gutwarwa neza.
Izi ELCBs nizo zikenewe kugirango uhuze kabiri kandi amahirwe yo kuba hari aho ahurira nubutaka kuri sisitemu yugarijwe bishobora kudakora detector.
