Kwinjira mu buryo bwimbitse kuri Residual Current Operated Circuit Breaker (RCBO)

Mu buryo bwa none bw'amashanyarazi bufite ingufu nke, umutekano n'ubwirinzi ni byo by'ingenzi cyane.Imashini ikoresha umuriro isigaye (RCBO) ni igikoresho cy'ingenzi cyo kurinda cyagenewe gukumira ibyago by'amashanyarazi nk'ihungabana ry'amashanyarazi n'inkongi ziterwa n'ikosa ry'amashanyarazi. Mu guhuza uburinzi bw'amashanyarazi arenze urugero, ubucucike bugufi, n'uburinzi bw'amashanyarazi asigaye, RCBO itanga umutekano usesuye ku bikorwa bitandukanye. Muri iyi nyandiko, turasuzuma imiterere y'ingenzi n'ibisobanuro bya tekiniki bya RCBO n'uruhare rwabyo mu kurinda sisitemu z'amashanyarazi.

Imikorere y'ingenzi ya RCBO

RCBO ihuza uburyo bwinshi bwo kurinda mu gikoresho kimwe. Inshingano zabo z'ibanze ni ukumenya ibintu byinshi birenze urugero, imiyoboro migufi, cyangwa imiyoboro isigaye (imiyoboro isohoka) no guhita ihagarika amashanyarazi kugira ngo hirindwe ingaruka zishobora kubangamira abantu n'imitungo. Ibi bituma RCBO zikora ibintu byinshi bitandukanye, kuko zikoreshwa ahantu henshi, kuva ku mazu kugeza ku bucuruzi n'inganda.

Ibisobanuro by'ingenzi bya tekiniki n'ibiranga

1. Ingano y'ubushyuhe: RCBO ziza mu buryo butandukanye bw'ubushyuhe bw'ubushyuhe bujyanye n'ubushyuhe butandukanye. Moderi zisanzwe nka CMTB1LE-32 na CMTB1LE-63 zikubiyemo ubushyuhe bw'ubushyuhe kuva kuri 3A kugeza kuri 63A. By'umwihariko, CMTB1LE-32 iboneka mu manota ya 3A, 6A, 10A, 16A, 20A, 25A, na 32A, bigatuma iba nziza ku mibare yoroheje kugeza ku iringaniye. Ku rundi ruhande, CMTB1LE-63 yagenewe imitwaro myinshi, ifite amanota ya 40A, 50A, na 63A, ikwiriye gukoreshwa mu ngufu nyinshi.

2. Ubushobozi bwo Guhagarika Ingufu mu Gihe gito: RCBO zakozwe kugira ngo zihagarike urujya n'uruza rw'amashanyarazi mu gihe habayeho uruziga rugufi. Icyitegererezo cya CMTB1LE-32 gifite ubushobozi bwo guhagarara bwa 6000A, bigatuma habaho guhagarara vuba iyo amashanyarazi atemba cyane. CMTB1LE-63 itanga ubushobozi bwo guhagarara butandukanye bitewe n'icyitegererezo cy'ubu: 6000A kuri 40A na 4500A kuri 50A na 63A. Ubu bushobozi bukomeye butuma RCBO yizewe mu gukumira kwangirika kw'ibikoresho by'amashanyarazi mu gihe cy'ikosa.

3. Imiterere y'inkingi: RCBO itanga uburyo bworoshye bwo guhuza inkingi, harimo 1P+N, 2P, 3P+N, na 4P, bigatuma zihuzwa n'imikorere y'amashanyarazi haba mu cyiciro kimwe n'icyiciro cya gatatu. Ubu buryo bworoshye bwo guhuza ibintu butuma habaho uburyo bwinshi bwo gukoresha mu gihe hakirindwa imiyoboro y'amashanyarazi, imiyoboro migufi, n'imiyoboro isigaye.

4. Ubwoko bw'Uburinzi bw'Umuriro Usigaye: Hari ubwoko bubiri bw'uburinzi bw'Umuriro Usigaye butangwa na RCBO—Ubwoko bwa C n'Ubwoko bwa D, bwagenewe imiyoboro iri hagati ya 3A na 63A. Ubwoko bwa C bukwiriye imiyoboro isanzwe, mu gihe Ubwoko bwa D bwagenewe imiyoboro ifite ubushobozi bwo gukurura cyangwa itwara imbaraga nyinshi, nka moteri cyangwa ibikoresho by'inganda. Ibi bituma RCBO ibasha guhangana n'ubwoko butandukanye bw'imizigo neza, ikarinda ko sisitemu iremerera cyane cyangwa kwangirika.

5. Uburyo bwo Gupima Umuvuduko w'Ingufu Zisigaye: RCBO zitanga urwego rutandukanye rwo kumva umuvuduko w'ingufu zisigaye, ari nacyo kintu cy'ingenzi mu kurinda umuvuduko w'ingufu zisigaye. Umuvuduko w'ingufu zisigaye zikoreshwa (IΔn) ukunze kuza mu buryo nka 30mA, 50mA, na 100mA, bigatuma igikoresho gishobora kubona umuvuduko w'ingufu zisohoka no kuzikuraho ingufu nibiba ngombwa. Byongeye kandi, uburyo bwo kumenya umuvuduko w'ingufu zisigaye zidafite ingufu (IΔno) bwa 15mA, 25mA, na 50mA butanga uburyo bwo kwirinda kugwa mu buryo butunguranye mu gihe bubungabunga umutekano.

6. Igihe cyo Gusubiza Byihuse: Iyo hagaragaye ikibazo cy'amashanyarazi, RCBO zikora ako kanya, mu gihe cyo gucika intege kitarenze amasegonda 0.1. Iki gikorwa cyihuse kigabanya ibyago byo kwangirika gukomeye cyangwa impanuka, gitanga uburinzi bwizewe ku bwoko butandukanye bw'amashanyarazi.

Porogaramu za RCBO

RCBO zikoreshwa cyane mu buryo bwo gukwirakwiza umuriro mu ngo, mu bucuruzi no mu nganda. Uburyo bwazo bwo kurinda buhuriweho butuma zikoreshwa cyane mu bidukikije by’amashanyarazi bigezweho, aho imizigo itandukanye kandi igoye ikunze kuba ihuriweho.

Ku bijyanye n'imirimo yo mu ngo, RCBO igenzura ko ibikoresho by'amashanyarazi byo mu rugo birinzwe imigezi iva mu mazi, hirindwa ibyago by'impanuka z'amashanyarazi. Mu bucuruzi, RCBO irinda ibikoresho by'ingenzi n'ibikorwaremezo ku makosa y'amashanyarazi, igenzura ko ubucuruzi bukomeza. Mu bikorwa by'inganda, cyane cyane aho ibikoresho nka moteri n'imashini ziremereye bikoreshwa, Type D RCBO itanga uburinzi bwiza ku migezi myinshi ishobora kubaho iyo hari imizigo nk'iyo itera imbaraga.

Umwanzuro

Imashini ikoresha umuriro usanzwe (RCBO) ni igice cy'ingenzi cy'uburinzi mu buryo bw'amashanyarazi bugezweho. Mu gushyiramo uburinzi bw'umuriro urenze urugero, ubugari bugufi, n'ubudasohoka, RCBO itanga umutekano wizewe kandi uhoraho. Ifite ibintu nk'ubushobozi bwo gucikamo ibice byinshi, kumenya umuriro usigaye, no gufata igisubizo vuba, RCBO zituma sisitemu z'amashanyarazi zigumana umutekano mu ngo, mu bucuruzi, no mu nganda. Guhitamo icyitegererezo cya RCBO gikwiye bitanga icyizere ko sisitemu z'amashanyarazi zikora neza kandi mu mutekano, zirinda abakoresha n'ibikoresho.
