The suction of magnet 8, therefore the direction movement that iron core 11 holds down permanent magnet 9 is slided, so as to pass through 12 band of contact connecting plate that insulate
It moves three movable contact springs 13 to move down, each movable contact spring 13 is made to be in contact with corresponding one group of static contact group, i.e., switch is closed, pulse electricity
Stream disappears after continuing 20ms, slides the attraction that iron core 11 is more than upper holding permanent magnet 8 by the attraction of lower holding permanent magnet 9,
Therefore slide iron core 11 and remain stationary as, the utility model remains closed；When switch need to be disconnected, forward direction is accessed to divide-shut brake coil 10
Current impulse, the direction that divide-shut brake coil 10 generates magnetic field is consistent with the magnetic direction that upper holding permanent magnet 8 generates, and the two is added
Magnetic field afterwards is more than the suction of lower holding permanent magnet 9, therefore slides the direction movement that iron core 11 keeps permanent magnet 8 upwards, so as to logical
Crossing insulation contact connecting plate 12 drives three movable contact springs 13 to move up, and makes each movable contact spring 13 and corresponding one group of static contact
Group phase separation, i.e. switch disconnect, and pulse current disappears after continuing 20ms, slide attraction of the iron core 11 by upper holding permanent magnet 8
It more than the attraction of lower holding permanent magnet 9, therefore slides iron core 11 and remains stationary as, the utility model remains open.
If 8 lower face of upper holding permanent magnet is S poles here, upper surface is N poles, and 9 upper surface of lower holding permanent magnet is S poles,
Lower face is N poles, then accesses forward current pulse to divide-shut brake coil 10 when needing to be closed, connect when need to disconnect to divide-shut brake coil 10
Enter reverse current pulses.
The utility model is easy to use, and i.e. the utility model is in and the position time-division is opened or closed in normal operation
Closing coil 10 is not charged, it is no longer necessary to maintain electromagnetic actuation and consumed energy, only need to protect in a moment for working condition switching
20ms consumption pulse currents are held, so as to consume a small amount of electric energy, therefore the utility model does not have to consumption electric energy for a long time, divide-shut brake
Coil 10 need not work long hours, and solve thing problems, such as that coil is electrified for a long time causes to generate heat, there are security risk, reduces
The noise that permanent magnet running hours are sent and the influence to magnetic field, reduce energy consumption, safety and environmental protection.
