Ese uzi ko Circuit Breakers ari iki?

Abakoresha amashanyarazi mu gihe cy'uruziga ni iki?

Imashini ikoresha amashanyarazi igamije kurinda uruziga rw'amashanyarazi kwangirika bitewe n'umuvuduko mwinshi w'amashanyarazi/umuvuduko mwinshi cyangwa umuvuduko mugufi izwi nka "circuit breaker". Inshingano yayo nyamukuru ni uguhagarika umuvuduko w'amashanyarazi nyuma y'uko relay zo kurinda zibonye ikibazo.

Imikorere ya Circuit Breaker.

Akamashini gakoresha amashanyarazi gakora nk'igikoresho cy'umutekano, bityo karinda kwangirika kwa moteri n'insinga iyo umuriro unyura mu ruziga rw'amashanyarazi urenze urugero rw'imiterere yawo. Ibi bibikora bikuraho umuriro mu ruziga iyo habayeho ikibazo cy'umutekano.

DC Circuit Breakers zikora zite?

Nk’uko izina ryabyo ribigaragaza, ibyuma bigabanya umuvuduko w’amashanyarazi (DC) birinda ibikoresho by’amashanyarazi bikora ku muvuduko w’amashanyarazi. Itandukaniro rikomeye hagati y’umuvuduko w’amashanyarazi n’umuvuduko w’amashanyarazi usimburana ni uko umuvuduko w’amashanyarazi muri DC uba uhoraho. Mu buryo bunyuranye, umuvuduko w’amashanyarazi muri Alternating Current (AC) uzenguruka inshuro nyinshi buri segonda.

Ni iyihe nshingano ya DC Circuit Breaker?

Amahame amwe yo kurinda ubushyuhe na rukuruzi akoreshwa kuri DC breakers nkuko akoreshwa kuri AC circuit breakers:
Uburinzi bw'ubushyuhe butera umuyoboro wa DC circuit breaker iyo amashanyarazi arenze agaciro kagenwe. Ubushyuhe bwo gukorana na Bimetallic buriyongera kandi bugatera umuyoboro wa DC breaker muri ubu buryo bwo kurinda. Uburinzi bw'ubushyuhe bukora vuba kuko amashanyarazi atanga ubushyuhe bwinshi kugira ngo yaguke kandi afungure umurongo w'amashanyarazi kuko amashanyarazi ari menshi. Uburinzi bw'ubushyuhe bwa DC circuit breaker burinda umuyoboro w'ubushyuhe urenze gato umuyoboro usanzwe ukoresha.
Iyo hari imiyoboro ikomeye y'amashanyarazi, uburinzi bwa rukuruzi butera DC circuit breaker, kandi igisubizo gihora gihita. Kimwe n'abakoresha AC circuit breaker, DC circuit breaker ifite ubushobozi bwo gucika bugaragaza umuyoboro ukomeye w'amashanyarazi ushobora guhagarara.
Kuba umuriro uhagaze uhoraho kuri DC circuit breakers bivuze ko circuit breaker igomba gufungura amashanyarazi kure kugira ngo ihagarike umuriro w'amashanyarazi. Uburinzi bwa magneti bwa DC circuit breaker burinda circuit ngufi n'amakosa kurusha kurenza umutwaro mwinshi.

Ubwoko Butatu bwa Miniature Circuit Breaker:

Ubwoko bwa B (ingendo ku muvuduko w'amashanyarazi inshuro 3-5).
Ubwoko bwa C (ingendo ku nshuro 5-10 z'umuvuduko w'amashanyarazi).
Ubwoko bwa D (ingendo ku gipimo cy'amashanyarazi inshuro 10-20).
