Circuit Breakers piav qhia: Kev Tiv Thaiv, Kev faib tawm, thiab kev siv
Circuit Breaker yog dab tsi?
Circuit Court breakers yog cov cuab yeej tiv thaiv tseem ceeb uas siv los txiav tawm qhov yuam kev hauv cov tshuab hluav taws xob. Lawv lub luag haujlwm tseem ceeb suav nrog kev tiv thaiv overload, tiv thaiv luv luv, thiab kev cais hluav taws xob.
Circuit Court breakers raug cais los ntawm daim ntawv thov rau hauv Miniature (MCB), Moulded Case (MCCB), Cua (ACB), Nqus (VCB), thiab Residual Tam Sim No (RCCB / RCBO) hom.
Lawv ua haujlwm ntawm thermal (overload) thiab magnetic (short-circuit) tripping mechanisms rau ceev disconnection.
Hauv lub cev muaj zog tswj systems, breakers pab raws li lub ntsiab tiv thaiv keyboards, ua hauj lwm nrog contactors (rau cov chaw taws teeb tswj) thiab thermal relays (rau kev tiv thaiv overload).
Kev xaiv yuav tsum xav txog ntsuas tam sim no, tawg peev xwm, ncej suav, thiab tripping nkhaus (eg., hom C rau kev tiv thaiv lub cev muaj zog) sib phim load thiab system xav tau kom raug.
