AQ 1000 Arc Quenching System

AQ 1000-AQ 1000 Arc Quenching System

Sipariş No : AQ 1000

AQ 1000 arc quenching system extinguishes arcing faults in systems with rated voltage of below 1000V within 3ms of arc initiation. The AQ 1000 Arc Quenching System is developed to limit the total arcing time to 3ms and to minimize or even eliminate the arcing fault thermal and pressure damaging effects. In most applications this will result in a calorie/cm2 energy release of less than 1. The AQ 1000 is fully reusable allowing for full system testing at site.

AQ 1000 arc quenching system extinguishes arcing faults in systems with rated voltage of below 1000V within 3ms of arc initiation. The AQ 1000 Arc Quenching System is developed to limit the total arcing time to 3ms and to minimize or even eliminate the arcing fault thermal and pressure damaging effects. In most applications this will result in a calorie/cm2 energy release of less than 1. The AQ 1000 is fully reusable allowing for full system testing at site.

The AQ 1000 is utilized in conjunction with the AQ 100 arc protection system. In case of an arc fault the AQ 100 detects the fault, initiates the AQ 1000 arc quenching system and simultaneously trips the fault feeding circuit breaker(s). The AQ 1000 creates a three-phase to ground low-impedance parallel path for fault current to flow thus extinguishing the arc fault. The total arcing time is 3ms.
