Isenyuka ry'umuzunguruko w'isi (ELCB)

Mu rwego rw'umutekano w'amashanyarazi, kimwe mu bikoresho by'ingenzi byakoreshejwe ni Isi yameneka (ELCB). Iki gikoresho cyingenzi cyumutekano cyashizweho kugirango gikumire inkuba n’umuriro wamashanyarazi mugukurikirana umuyaga unyura mumuzunguruko no kuwuzimya mugihe hagaragaye voltage iteje akaga. Muri iyi blog, tuzareba neza ELCB icyo aricyo nuko iturinda umutekano.

ELCB nigikoresho cyumutekano gikoreshwa mugushiraho ibikoresho byamashanyarazi hamwe nubutaka bukabije kugirango wirinde guhungabana. Cyakora mukumenya voltage ntoya yazimiye mubikoresho byamashanyarazi kumurongo wibyuma no guhagarika umuzunguruko mugihe hagaragaye voltage iteje akaga. Intego yacyo nyamukuru ni ukubuza abantu n’inyamaswa kwangizwa n’amashanyarazi.

Ihame ryakazi rya ELCB riroroshye cyane. Ikurikirana ubusumbane buriho hagati yabayobora icyiciro nuyobora utabogamye. Mubisanzwe, umuyoboro unyura mucyiciro cya fonctionnement hamwe numuyoboro unyura mumashanyarazi atabogamye agomba kuba angana. Ariko, mugihe habaye ikosa, nkukubera insinga zitari nziza cyangwa izitera itera umuyaga gutemba hasi, habaho ubusumbane. ELCB itahura ubwo busumbane kandi igabanya vuba amashanyarazi kugirango ikumire ibyangiritse.

Hariho ubwoko bubiri bwa ELCBs: voltage ikoreshwa na ELCBs na ELCB ikoreshwa nubu. Umuyagankuba ukoreshwa na ELCBs ugereranya ibyinjira nibisohoka, mugihe ELCB ikoreshwa nubu ikoresha transformateur ya toroidal kugirango hamenyekane ubusumbane ubwo aribwo bwose butemba buciye mu cyiciro kandi butabogamye. Ubwoko bwombi bumenya neza kandi bugasubiza amakosa yumuriro w'amashanyarazi.

Ni ngombwa kumenya ko ELCBs itandukanye na gakondo yamenagura imashanyarazi, igenewe kurinda imizigo irenze urugero nizunguruka. Mugihe imiyoboro yamashanyarazi idashobora guhora itahura amakosa yo murwego rwo hasi, ELCBs yagenewe byumwihariko kugirango isubize amashanyarazi mato mato kandi ikingire amashanyarazi.

Muri make, icyuma cyangiza isi (ELCB) nigikoresho cyingenzi cyumutekano kigira uruhare runini mukurinda inkuba n’umuriro. Mugukurikirana imigendekere yubu no gusubiza ubusumbane cyangwa amakosa, ELCB irashobora guhagarika vuba ingufu no gukumira ingaruka zose zishobora kwangiza abantu ninyamaswa. Mugihe dukomeje gushyira imbere umutekano murugo no mukazi, ni ngombwa kumva akamaro ka ELCBs nuburyo bakora.
