Mufananidzo weMinitary Circuit Breaker (MCB) CJM7-125

Miniature Circuit Breaker (MCB) CJM7-125

Tsananguro pfupi:

CJM7-125 Miniature circuit breakers (MCBs) inovimbisa kuchengetedzeka kwemagetsi mudzimba nemamiriro akafanana, akadai semahofisi nedzimwe zvivakwa pamwe nekushandiswa kwemaindasitiri nekudzivirira kuiswa kwemagetsi kubva pakuwedzerwa kwemagetsi uye mashort circuit. Kana paine chikanganiso chaonekwa, miniature circuit breaker inodzima otomatiki circuit yemagetsi kudzivirira kukuvara kwewaya uye kudzivirira njodzi yemoto. Zvichivimbisa kuvimbika uye kuchengetedzeka kwevanhu nezvinhu, MCBs dzine nzira mbiri dzekugumburwa: nzira yekunonoka yekugumburwa kwemafuta ekudzivirira overload uye nzira yekugumburwa nemagnetic yekudzivirira short circuit. Kazhinji rated current i63, 80, 100A uye rated voltage i230/400VAC. frequency i50/60Hz. zvinoenderana neIEC60497/EN60497 standards.

Chii chinonzi MCB?

Muchina Mudiki weDunhu reMadhiraivha(MCB) imhando yecircuit breaker ine saizi diki. Inocheka circuit yemagetsi pakarepo kana paine mamiriro asina kunaka mumagetsi, akadai sekuchaja zvakanyanya kana kuti short-circuit current. Kunyangwe mushandisi anogona kudzosera MCB patsva, fuse inogona kuona mamiriro ezvinhu aya, uye mushandisi anofanira kuitsiva.

Kana MCB iine simba remagetsi rinoenderera mberi, bimetallic strip inodziya uye inokotama. Chibatiso chemagetsi chinoburitswa kana MCB ikabvisa bimetallic strip. Kana mushandisi akabatanidza electromechanical clasp iyi kune mashandiro ekushanda, inovhura microcircuit breaker contacts. Nekuda kweizvozvo, zvinoita kuti MCB izime uye imise kuyerera kwemagetsi. Mushandisi anofanira kuvhura MCB yega yega kuti adzorere kuyerera kwemagetsi. Mudziyo uyu unodzivirira zvikanganiso zvinokonzerwa nemagetsi akawandisa, overload, uye short circuits.
