Ang drive module gitugyan sa circuit breaker, nga gisilbing kontrol ug online monitoring device alang sa circuit breaker system. Ang housing sa drive module gihimo sa aluminum alloy, nga makaepektibo nga mag-shield sa electromagnetic interference, ang mao kini naglakip og lima ka unit circuits:
Switching power supply unit: Nagsilbi niini aron mobag-o sa external auxiliary power supply ngadto sa power source nga gamiton sa internal circuit.
Charging circuit unit: Nagsilbi niini aron mobag-o sa electrical energy para sa closing ug opening capacitors.
Discharge circuit unit: Nag-inject niini og positive excitation current o reverse demagnetization current sa excitation coil sa circuit breaker mechanism aron mogamit o mobuang sa mechanism.
I/O interface unit: Gisilbi niini aron mobati sa opening ug closing commands ug input sa status sa circuit breaker.
Control Unit: Monitors ug controls niini ang operasyon sa tanang circuit breaker.
Basic function
Maghatag og excitation current para sa closing operation
Maghatag og de-magnetizing current para sa opening operation
On-line monitoring
Alarm para sa abnormal movement sa auxiliary switch
Manual trip alarm
Anti-jump and locking function
Ang drive module mismo adunay anti-jump locking function
application
Driving MS Series circuit-breaker
