A siri na MS5-12-630/20-XX a cikin circuit breakers suna da shugaban semi-hard magnetic material actuator mechanisms. Ana amfani da ita a cikin hanyoyi na AC na uku da rated voltage 12KV da frequency 50-60Hz, idan yana daya daga tsohon kula da yanayi. Yana da muhimmanci wajen yanayin da ba da shawarwari ko kula da yanayi na short-circuit currents. A cikin wannan siri na circuit breakers akwai circuit breaker da drive module.
Tsarin circuit breaker
Har phase yana da aktuator mechanism baki daya, wanda ake sauka perpendicularly da axially da vacuum interrupter. Sauran excitation coils suka fi tsakiyar parallel. Sauran three-phase actuators
su ka yi aiki a gaba da tsakiyar synchronous shaft da kuma karshen auxiliary switch position signal output.
Vacuum interrupter ya samu external bellows, da bellows suka gina ne da stainless steel lamination welding process. Contact opening distance yana 8mm da overtravel yana 2mm. Contacts suka gina ne da zama da principle of longitudinal magnetic field arc extinguishing.
Contact pressure spring a insulating rod don in tabbatar da contact daidai da moving da static contacts na VI da kuma cewa abubuwan da suka yi suna da shawarwa da operational characteristic
requirements.
Insulating frame yana gina ne da SMC, wanda ke fuskantar upper da lower terminals, operating insulating rods, flexible connections, vacuum interrupters da wasu abubuwan, tare da role of insulation da support.
Amfani da ita
Daya daga air insulated switchgear.
