Sobanukirwa n'akamaro ko guhinduranya ELCB mumashanyarazi

Mu rwego rwubwubatsi bwamashanyarazi, umutekano nuburinzi nibyingenzi byingenzi. Kimwe mu bintu by'ingenzi bigize umutekano w’umuzunguruko ni icyuma cya ELCB, kizwi kandi ku isi imeneka. Ku bijyanye no kurinda umuzunguruko, JCM1 ikurikirana ya plastike yamashanyarazi yamashanyarazi igaragara nkibisubizo byizewe kandi byateye imbere. Yatejwe imbere ikoresheje igishushanyo mbonera n’ikoranabuhanga mu gukora, iyi mashanyarazi yamenetse ifite ibintu byinshi bituma iba ikintu cyingenzi muri sisitemu y’amashanyarazi.

Imashanyarazi ya JCM1zashizweho kugirango zitange uburinzi bwuzuye harimo kurinda ibicuruzwa birenze urugero, kurinda imiyoboro ngufi no kurinda voltage. Ibi biranga ingenzi kurinda imirongo ishobora guteza ingaruka no kurinda umutekano wibikoresho nababikora. Imashanyarazi yamashanyarazi ifite voltage yagereranijwe igera kuri 1000V, ikwiranye no guhinduranya gake na moteri itangira, kandi irakwiriye mubikorwa bitandukanye.

Kimwe mu bintu nyamukuru biranga iJCM1 yamenekani igipimo cyacyo cyo gukora kugeza kuri 690V, bigatuma gikwiranye na sisitemu zitandukanye. Haba kumashini zinganda, ibikoresho byubucuruzi cyangwa porogaramu zo guturamo, ibyuma byumuzunguruko bitanga uburinzi bwizewe mubisabwa na voltage zitandukanye. Mubyongeyeho, ibipimo bitandukanye biriho birahari kuva 125A kugeza 800A, byemeza ko ibyuma byumuzunguruko bishobora gutegekwa kubisabwa byumutwaro wihariye, bitanga ibintu byoroshye kandi bigahinduka mubikorwa bitandukanye.

Imashanyarazi ya JCM1 gukurikiza ibipimo bya IEC60947-2 kandi ukurikize amabwiriza mpuzamahanga yumutekano n’imikorere, biha abakoresha ikizere mu kwizerwa no mu bwiza. Uku kubahiriza gushimangira ibyo twiyemeje gutanga ibicuruzwa byujuje ubuziranenge bw’inganda, tukareba ko bishobora kwinjizwa mu buryo butandukanye mu mashanyarazi atandukanye mu gihe umutekano no gukora neza.

Ihinduka rya ELCB ryinjijwe muri JCM1 yameneka yamashanyarazi irusheho kongera ubushobozi bwo kurinda. Guhindura ELCB byashizweho kugirango hamenyekane ikintu cyose cyatembye ku isi, gitanga urwego rwumutekano rwinshi muguhagarika vuba ingufu mugihe habaye amakosa. Iyi mikorere ni ngombwa mu gukumira ihungabana ry’amashanyarazi no kugabanya ingaruka ziterwa n’umuriro w'amashanyarazi, bigatuma iba ikintu cy'ingenzi mu mashanyarazi agezweho.

JCM1 ikurikirana ya plastike yamashanyarazi yamenetse, hamwe nibikorwa byayo bigezweho hamwe na ELCB ihindura, byerekana iterambere ryinshi muburyo bwo kurinda umuziki. Ubushobozi bwayo bwo gutanga uburinzi bwuzuye, bujyanye no kubahiriza amahame mpuzamahanga, bituma ihitamo kwizewe kubikorwa bitandukanye. Mugusobanukirwa n'akamaro ko guhinduranya ELCB n'uruhare rwabo mukuzamura umutekano w'amashanyarazi, abayikoresha barashobora gufata ibyemezo byuzuye muguhitamo ibisubizo birinda umuzunguruko, amaherezo bikagira uruhare mumutekano rusange no kwizerwa bya sisitemu y'amashanyarazi.
