Ingufu zisigaye: amahitamo ya mbere yo gukoresha amashanyarazi mu buryo bwizewe

GusobanukirwaRCCB: Igice cy'ingenzi cy'umutekano w'amashanyarazi

Mu isi y’umutekano w’amashanyarazi, icyuma gihagarika amashanyarazi gisigara (RCCB) ni igikoresho cy’ingenzi cyagenewe kurinda abantu n’imitungo ingaruka z’amashanyarazi. Uko tugenda dusesengura cyane uburyo RCCB ikora, biragaragara ko iki gikoresho gikora uruhare runini mu gushyiraho amashanyarazi agezweho kugira ngo gikomeze kuba umutekano kandi kibe cyizerwa.

RCCB ni iki?

RCCB, izwi kandi nka residual current device (RCD), ni igikoresho cy'amashanyarazi gihagarika uruziga iyo kibonye ubusumbane mu muyoboro w'amashanyarazi hagati y'insinga zikora n'izitagira umupaka. Ubu busumbane bushobora guterwa n'impamvu nyinshi, nko gukoresha insinga zitari zo, kwangirika k'ubushyuhe, cyangwa umuntu ukora ku nsinga zikora ku bw'impanuka. RCCB ikurikirana buri gihe umuyoboro w'amashanyarazi unyura muri ruziga, kandi iyo ibonye umuyoboro w'amashanyarazi usohoka (ubusanzwe uba uri hasi ya 30 mA), iragwa ikanahagarika amashanyarazi mu masegonda make. Ubu buryo bwihuse bwo gusubiza ni ingenzi mu gukumira impanuka y'amashanyarazi no kugabanya ibyago by'inkongi z'umuriro w'amashanyarazi.

RCCB ikora ite?

Ihame ry'imikorere rya RCCB rishingiye ku ihame ry'umuvuduko w'amashanyarazi utandukanye. Rigizwe n'inkingi y'icyuma n'imirongo ibiri: imwe y'insinga ikora n'indi y'insinga itagira aho ibogamiye. Mu bihe bisanzwe, imigezi inyura muri iyo mirongo yombi ingana kandi imbaraga za rukuruzi zikorwa n'imirongo zirahanagurana. Ariko, iyo habayeho ikosa, nko kuvogera umuvuduko w'amashanyarazi ugana ku butaka, uburinganire burasenyuka, bigatuma habaho itandukaniro mu mbaraga za rukuruzi. Uku kutumvikana gutuma RCCB igwa, igasenya uruziga kandi ikarinda ibyago bishobora kubaho.

Ubwoko bwa RCCB

Hari ubwoko butandukanye bwa RCCB, buri bwoko bufite intego yihariye. Ubwoko bukunze kugaragara burimo:

1. RCCB ifite inkingi ebyiri: Ikoreshwa mu miyoboro y’amashanyarazi ifite urwego rumwe, ikunze kuboneka mu mihana.
2. RCCB ifite inkingi enye: Yagenewe imiyoboro y'ibice bitatu, ikoreshwa cyane mu nganda n'ubucuruzi.
3. Ubwoko bwa AC RCCB: imenya umuyoboro usimburana (AC) usigaye.
4. Ubwoko bwa A RCCB: ishobora kumenya AC n'umuvuduko wa DC usigaye, ukwiriye imiyoboro y'ibikoresho by'ikoranabuhanga.

Akamaro ka RCCB mu mutekano w'amashanyarazi

Akamaro ka RCCB ntigakwiye gukabya. Ni ingenzi mu kubungabunga umutekano w'ibikoresho by'amashanyarazi mu ngo, mu biro no mu nganda. Mu kurinda impanuka y'amashanyarazi, RCCB zifasha mu kubungabunga ubuzima, cyane cyane ahantu hatose nko mu bwiherero no mu gikoni. Byongeye kandi, zigira uruhare runini mu gukumira inkongi z'amashanyarazi ziterwa n'insinga cyangwa ibikoresho bitari byo.

Gushyiraho no kubungabunga

Kugira ngo imikorere irusheho kuba myiza, RCCB zigomba gushyirwaho n'umuhanga mu by'amashanyarazi usobanukiwe neza ibisabwa n'amashanyarazi. Gupima no kubungabunga buri gihe nabyo ni ngombwa kugira ngo ibikoresho bikore neza. RCCB nyinshi zifite akabuto ko gupima gatuma umukoresha ashobora kugenzura imikorere yazo buri gihe. Ni byiza ko RCCB igeragezwa nibura rimwe mu kwezi kugira ngo imenye neza ko ikora neza.

Muri make

Muri make, icyuma gihagarika amashanyarazi gisigara (RCCB) ni igice cy'ingenzi cy'uburyo bw'umutekano w'amashanyarazi. Kubera ubushobozi bwacyo bwo kumenya no gusubiza ibibazo by'amashanyarazi, ni igikoresho cy'ingenzi mu kurinda ubuzima n'umutungo ingaruka z'amashanyarazi. Akamaro ka RCCB kazakomeza kwiyongera uko ikoranabuhanga ritera imbere n'uburyo bw'amashanyarazi burushaho kuba ingorabahizi, bigakomeza kugaragaza ko ari ngombwa kumenya no gusobanukirwa iki gikoresho cy'ingenzi cy'umutekano. Haba mu ngo, mu bucuruzi cyangwa mu nganda, RCCB zikomeje kuba inkingi y'umutekano w'amashanyarazi, zituma abakoresha bose bagira amahoro yo mu mutima.
