Utwuma duto tw’amashanyarazi: ibisubizo bito by’umutekano

GusobanukirwaUdukingirizo duto tw'uruziga: Intwari zitavugwa cyane mu mutekano w'amashanyarazi

Mu isi igoye y’amashanyarazi, umutekano ni ingenzi cyane. Kimwe mu bintu by’ingenzi cyane mu kurinda uyu mutekano ni miniature circuit breaker (MCB). Nubwo akenshi birengagizwa, ibi bikoresho bito bigira uruhare runini mu kurinda circuits kurenza urugero no kwangirika kwa circuits ngufi. Iyi blog irasuzuma akamaro, imiterere n’ibyiza bya MCBs, isobanura impamvu ari ingenzi haba mu ngo no mu bucuruzi.

Akamashini gato ko gukata uruziga ni iki?

Akamashini gato gakoresha amashanyarazi, gakunze kuvugwa mu magambo make nka MCB, ni icyuma gikoresha amashanyarazi cyikora kugira ngo kirinde kwangirika kw'amashanyarazi bitewe n'umuvuduko w'amashanyarazi ukabije. Bitandukanye na za fuse, zigomba gusimburwa nyuma yo gukoreshwa rimwe, MCB zishobora kongera gukoreshwa, bigatuma ziba igisubizo cyoroshye kandi gihendutse cyo kurinda amashanyarazi.

MCB ikora ite?

Akamaro nyamukuru ka MCB ni uguhagarika urujya n'uruza rw'amashanyarazi iyo hagaragaye ikibazo. Ibi bigerwaho binyuze mu buryo bubiri bw'ingenzi: ubushyuhe n'ubukuru.

1. Uburyo bwo gushyushya: Ubu buryo bukora bushingiye ku ihame ryo gutanga ubushyuhe. Iyo habayeho umuvuduko mwinshi w'amashanyarazi, umuvuduko ukabije w'amashanyarazi ushobora gutuma umurongo wa bimetallic uri mu gice gito cy'amashanyarazi ushyuha kandi ugahinduka. Iki gikorwa cyo gupfunyika gica icyuma, kikangiza uruziga kandi kigahagarika urujya n'uruza rw'amashanyarazi.

2. Uburyo bwa Magnetic: Ubu buryo bwagenewe gusubiza imiyoboro migufi. Iyo umuyoboro mugufi ubaye, kwiyongera gutunguranye k'umuyoboro w'amashanyarazi bituma imbaraga za rukuruzi zirushaho gukomera bihagije kugira ngo zikure umugozi, hanyuma ugaca umuyoboro ugahagarika umuyoboro.

Ubwoko bw'icyuma gito gikoresha amashanyarazi

Hari ubwoko butandukanye bwa MCB, buri bumwe bwagenewe guhangana n'urwego rutandukanye rw'ikoreshwa rigezweho n'iry'umwihariko. Ubwoko bukunze kugaragara burimo:

1. Ubwoko bwa B: Izi MCB zigwa iyo umugezi ugeze ku nshuro 3 kugeza kuri 5 z'umugezi usanzwe. Ubusanzwe zikoreshwa mu ngo aho ubushobozi bwo gutera umugezi mwinshi ari buke.

2. Ubwoko bwa C: Izi MCB zigwa iyo umuvuduko w'amashanyarazi ugeze ku nshuro 5 kugeza ku 10 z'umuvuduko w'amashanyarazi. Zikwiriye gukoreshwa mu bucuruzi no mu nganda zikoresha ibikoresho bifite umuvuduko mwinshi w'amashanyarazi, nka moteri na transfoma.

3. Ubwoko bwa D: Izi MCB zigwa iyo umugezi ugeze ku nshuro 10 kugeza kuri 20 z'umugezi usanzwe. Zikoreshwa mu nganda zidasanzwe aho umugezi ukabije witezweho kwiyongera cyane.

Ibyiza byo gukoresha MCB

1. Umutekano Ukomeje: MCB itanga uburinzi bwizewe bw'amakosa y'amashanyarazi, ikagabanya ibyago by'inkongi z'umuriro n'ibyangiritse by'ibikoresho.

2. Uburyo bworoshye: Bitandukanye na za fuse, za miniature circuit breakers zishobora kongera gukoreshwa nyuma yo kugwa nta zindi zisimbuwe, bigabanyiriza igihe cyo kudakora.

3. Kuvuga neza: MCB zitanga uburinzi nyabwo mu guteshuka ku rugero runaka rw'umuvuduko w'amashanyarazi, zigenzura ko umuyoboro w'amashanyarazi ufite ikibazo ari wo wonyine uhagarara mu gihe igice gisigaye cy'umuyoboro gikomeza gukora.

4. Kuramba: MCB zakozwe kugira ngo zishobore kwihanganira ingendo nyinshi, bigatuma ziba igisubizo kirambye cyo kurinda urujya n'uruza rw'amashanyarazi.

Ishyirwa mu bikorwa rya MCB

MCB ifite porogaramu nyinshi zirimo:

1. Inzu zo guturamo: Irinda imiyoboro y'amashanyarazi yo mu rugo imitwaro myinshi n'imiyoboro migufi, irinda umutekano w'abayikoresha n'ibikoresho.

2. UBUCURUZI: Burinda sisitemu z'amashanyarazi mu biro, mu maduka n'ahandi hantu hakorerwa imirimo y'ubucuruzi kwangirika kw'igihe gito no kwangirika kw'ibikoresho.

3. Inganda: Gutanga uburinzi bukomeye ku mashini n'ibikoresho by'inganda, kugabanya ibyago byo kwangirika kw'amashanyarazi no kunoza imikorere.

Muri make

Nubwo utumashini duto duto dukoresha amashanyarazi ari duto, ingaruka zatwo ku mutekano w'amashanyarazi ni nini cyane. MCB zigira uruhare runini mu kurinda sisitemu z'amashanyarazi mu ngo, ubucuruzi n'inganda binyuze mu gutanga uburinzi bwizewe kandi bunoze ku birebana n'amashanyarazi no kurinda amashanyarazi make. Uko ikoranabuhanga rikomeza gutera imbere, akamaro k'izi ntwari zitaramenyekana mu mutekano w'amashanyarazi kazakomeza kwiyongera, tuzemeza ko sisitemu zacu z'amashanyarazi zizakomeza kugira umutekano no gukora neza mu myaka iri imbere.
