Ang serye ng MS2-12-630/20-XX na circuit breakers ay indoor switchgear na batay sa mekanismo ng aktuator na semi-hard magnetic material. Ginagamit ito sa three-phase AC power systems na may rated voltage na 12KV at frequency na 50-60Hz, bilang isang protective at control device. Ito ay partikular na angkop para sa madalas na operasyon sa rated current o maraming pag-break ng short-circuit currents. Ang serye ng mga circuit breaker na ito ay kasama ang circuit breaker at ang drive module.
Ang istraktura ng circuit breaker
Bawat phase ay may isang aktuator mechanism, na inilalapat nang perpendikular at axial sa vacuum interrupter. Ang tatlong excitation coils ay konektado sa parallel. Ang three-phase actuator
mechanisms ay nagpapahayag ng synchronous action sa pamamagitan ng synchronous shaft at sumisiguro na maglabas ng auxiliary switch position signal output nang sabay-sabay.
Ang vacuum interrupter ay gumagamit ng external bellows, at ang bellows ay gawa sa stainless steel lamination welding process. Ang contact opening distance ay 8mm at ang overtravel ay 2mm. Ang mga contact ay disenyo batay sa prinsipyong longitudinal magnetic field arc extinguishing.
Contact pressure spring sa insulating rod upang masigurong maayos ang contact sa pagitan ng moving at static contacts ng VI at na ang mga related actions ay tumutugon sa operational characteristic
requirements.
Ang insulating frame ay gawa ng SMC, na nakakalampot sa upper at lower terminals, operating insulating rods, flexible connections, vacuum interrupters at iba pang components, na naglalaro ng papel ng insulation at support.
Paggamit
Suitable para sa air insulated switchgear, para sa arc elimination line selection, phase selection, bypass at iba pang aplikasyon.
