Ibyiyumvo-Byinshi RCBO hamwe nigisubizo cyihuse hamwe nuburinzi bwizewe burenze urugero

RCBOitanga ibintu byinshi harimo kurinda guhuriza hamwe guhuza ibikorwa birenze urugero no gukingira ibikoresho mubikoresho bimwe. Ukurikije porogaramu, itanga urwego rwimikorere itandukanye nka 10mA, 30mA, 100mA na 300mA kandi ihuye nibisabwa umutwaro wumuzunguruko ufite urwego rwa 16A, 20A cyangwa 32A. Itanga ibishushanyo bitandukanye nka pole imwe (SP) cyangwa pole ebyiri (DP) kugirango ihuze sisitemu zitandukanye. Igikoresho gihora gikurikirana imiyoboro iri mu nsinga zishyushye kandi zidafite aho zibogamiye ningendo niba hari ubusumbane (bwerekana kumeneka hasi) cyangwa niba amashanyarazi arenze ubushobozi bwagenwe bitewe nuburemere burenze cyangwa umuzenguruko muto.

RCBOs zikoreshwa cyane mubikorwa byo murugo, cyane cyane ahantu hatose nko mu gikoni no mu bwiherero, kugirango birinde imiyoboro yo murugo. Zirakenewe kandi mubucuruzi ninganda, aho zirinda ibikoresho nabakozi mubidukikije bifite imitwaro myinshi yamashanyarazi. Zikoreshwa kandi mumuzunguruko ukomeye zisaba kurinda birenze urugero no kumeneka, nkibikoresho byoroshye cyangwa ahantu hashobora kwibasirwa cyane. Ubwinshi bwabo butuma bagize igice cyingenzi muri sisitemu zamashanyarazi zigezweho.

RCBOszagenewe kubika umwanya nkuko zihuza imikorere ibiri mugikoresho kimwe, bikagabanya ibikenerwa RCDs na MCB zitandukanye. Batezimbere kandi umutekano batanga uburinzi bwuzuye kubitera amashanyarazi, harimo kumeneka namakosa arenze urugero. Bemeza gutembera gutoranya, bivuze ko umuzenguruko utari wo gusa waciwe, bikagabanya kwivanga nibindi bice bya sisitemu y'amashanyarazi. Ibi bituma bakora igisubizo cyiza kandi cyizewe haba mubikorwa byo guturamo no mu nganda.

Kwinjiza no kubungabungaRCBOsbigomba gukorwa n’umuyagankuba wujuje ibyangombwa ukurikije amabwiriza y’amashanyarazi yaho (urugero: IEC 61009 cyangwa BS EN 61009). Kwipimisha buri gihe ukoresheje buto yikizamini kubikoresho birasabwa kwemeza imikorere ikwiye n'umutekano ukomeje. RCBOs igira uruhare runini mugushiraho amashanyarazi agezweho muguhuza kurinda birenze urugero nibisigara mugikoresho kimwe, bigatanga uburinzi bubiri kandi bikazamura umutekano rusange muri sisitemu yamashanyarazi.
