Permanent magnet AC contactor works

Permanent magnet AC contactor does not work, dynamic and static contact is released, such as to attract the coil is energized, the core will produce a magnetic field, the contactor contacts from the release position to move quickly pull position, but also for
Moving contacts stored power transformers. Once arcing between contacts, electromagnetic gap becomes smaller, then the permanent force will surge, pull speed (Pick-up time is less than 20ms), thus greatly reducing the suction timely contact ablation, permanent force pull the contacts maintained after circuit breakers torque constant irrespective of network voltage fluctuations, even in the Pro dielectric voltage contacts also pull off action, the contact does not flutter. Contactor contact pull, the current control module will attract the coil current off, then the coil does not work, no power, the coil current is zero, no energy, no heat coils, of course, not burned, time rely entirely on the contacts maintained in permanent force pull the state. At the same time, smart electronic circuit control voltage Electric transformer to work, when the voltage detection module detects a control voltage is below a predetermined voltage value, the suction timely stored energy will pass to reverse current to the coil, so that moving iron between the core and the static core of the same polarity magnetic repulsive force, and with the release of the joint action of the spring permanent magnet AC contactor contact release, then release the energy of traditional electromagnetic contactor several times, the release rate electromagnetic contactor is 3 to 5 times (less than 18ms), effectively reducing the contact time between the release of arc burning time. When the control voltage is higher than a predetermined voltage value, even if the voltage fluctuations will not affect the dynamic and static holding force between the contacts, the contacts will not be the same tremor, completely avoid contact burned phenomenon.
