Gusobanukirwa RCCB: Imashini igabanya ubushyuhe bw'amashanyarazi

Mu isi y’umutekano w’amashanyarazi, ibyuma bigabanya ubushyuhe bw’amashanyarazi (RCCB) bigira uruhare runini mu kurinda abantu n’imitungo ingaruka z’amashanyarazi. Ibi bikoresho byagenewe gukumira impanuka y’amashanyarazi no kugabanya ibyago by’inkongi z’umuriro ziterwa n’ikosa ryo ku butaka. Iyi nkuru izasuzuma neza imikorere, akamaro, n’ikoreshwa rya RCCB.

RCCB ni iki?

RCCB (Residual Current Circuit Breaker) ni igikoresho cy'amashanyarazi gihagarika urujya n'uruza iyo kibonye ubusumbane hagati y'insinga zikora (phase) n'izitagira aho zibogamiye. Ubu busumbane bwerekana ko urujya n'uruza rurimo kuva ku butaka, bishobora guterwa n'insinga zitameze neza, kwangirika kw'ubushyuhe, cyangwa gukorana n'ibice bikora ku buryo butunguranye. RCCB ihora igenzura urujya n'uruza runyura muri uru ruza kandi ishobora kugira icyo ikora ku busumbane ubwo aribwo bwose mu masegonda make kugira ngo irebe ko hari umutekano.

RCCB ikora ite?

RCCB ikora ipima umuyoboro unyura mu nsinga zishyushye n'izidafite aho zibogamiye. Ubusanzwe, umuyoboro unyura mu ruziga unyuze mu nsinga zishyushye ugomba kungana n'umuyoboro ugaruka unyuze mu nsinga zidafite aho zibogamiye. Iyo habayeho itandukaniro, RCCB ibona ubu busumbane.

Iyo RCCB ibonye umuriro usohoka, itera uburyo bufungura urusobe rw'amashanyarazi, bityo ikarinda umuriro ushobora gushoka cyangwa gushya. RCCB zitandukanye mu buryo bwo kumva, aho amanota asanzwe y'umuriro ari 30mA (yo kwirinda umuntu ku giti cye) na 100mA cyangwa 300mA (yo kurinda inkongi).

Akamaro ka RCCB

Akamaro ka RCCB ntikagombye gukabya. Ni inzira y'ingenzi yo kwirinda impanuka z'amashanyarazi. Dore zimwe mu mpamvu z'ingenzi zituma RCCB ari ingenzi:

1. Kurinda impanuka y'amashanyarazi: RCCBs zagenewe kurinda abakozi binyuze mu gukuraho urusobe rw'amashanyarazi iyo hagaragaye ikosa. Ibi ni ingenzi cyane cyane mu bidukikije aho abakozi bashobora gukora ku bice bizima.

2. Kwirinda inkongi: Ikosa ry'amashanyarazi rishobora gutera ubushyuhe bwinshi n'inkongi. RCCB zifasha gukumira inkongi z'amashanyarazi no kurinda ibintu n'ubuzima binyuze mu kumenya amazi ashobora gutera ubushyuhe bwinshi.

3. Kuzuza amahame ngenderwaho y'amashanyarazi: Ibihugu byinshi bisaba ko hashyirwaho ibyuma bigabanya umuriro w'amashanyarazi (RCCBs) mu mazu yo guturamo n'ay'ubucuruzi. Kuzuza aya mahame ntibyongera umutekano gusa ahubwo binatuma amashanyarazi yujuje ibisabwa n'amategeko.

4. Amahoro yo mu Mutima: Gushyiramo imashini igabanya ubushyuhe bw'amashanyarazi (RCCB) bitanga amahoro yo mu mutima ku ba nyir'amazu n'abakora ubucuruzi. Bashobora gukoresha ibikoresho byabo by'amashanyarazi batitaye ku ngaruka zishobora kubaho.

Ishyirwa mu bikorwa rya RCCB

RCCB zifite uburyo butandukanye bwo gukoresha, harimo:

- Inyubako zo guturamo: Mu ngo, RCCB zikunze gushyirwa mu kibaho gikuru cyo gukwirakwizamo ibikoresho kugira ngo zirinde imiyoboro itanga amashanyarazi ku masoko, amatara n'ibikoresho.

- Ibigo by'ubucuruzi: Ibigo bikunze gukoresha RCCBs mu kurinda ibikoresho no kurinda umutekano w'abakozi n'abakiriya.

- Imiterere y'inganda: Mu nganda, RCCB ni ingenzi mu kurinda imashini n'abakozi amakosa y'amashanyarazi.

- Gushyira hanze: RCCB zikoreshwa kandi mu gushyiraho amashanyarazi yo hanze nko mu busitani no mu bidendezi aho ibyago byo guhungabana kw'amashanyarazi biri hejuru.

Muri make

Ibice bigabanya umuriro w’amashanyarazi (RCCBs) ni igice cy’ingenzi cy’imikorere y’amashanyarazi igezweho. Bifite ubushobozi bwo kumenya no gusubiza ikibazo cy’ubusumbane bw’amashanyarazi, ni ibikoresho by’ingenzi mu kurinda ubuzima n’umutungo ingaruka z’umuriro n’amashanyarazi. Uko ikoranabuhanga rigenda ritera imbere n’imikorere y’amashanyarazi irushaho kuba ingorabahizi, RCCBs zizakomeza kugira uruhare runini mu kurinda umutekano w’amashanyarazi mu ngo, mu kazi no mu bibanza bihuriramo abantu benshi. Gushora imari mu bikoresho byiza bya RCCBs no kugenzura ko byashyizweho kandi bibungabungwa neza ni intambwe ikomeye igana ku bidukikije birangwamo umutekano w’amashanyarazi.
