Therefore, when the main power supply is normal, current flows in a fixed direction through the excitation coil 6, but if an abnormality occurs, the excitation coil 6 is connected to an appropriate power supply circuit (not shown) so that the current flows in the opposite direction to the excitation coil 6. This is what is being done.

In the embodiment of this invention related to the above structure,
Now, the N pole of the permanent magnet 7 and the S pole of the permanent magnet 8 are installed so as to face each other, and the current flowing through the excitation coil 6 is set so that it flows clockwise when the main power supply is normal. To explain the operating situation in this case, Fig . 4 shows the state when the main power supply is normal. 8 is the induced magnetic flux, and S and N indicate the S pole and N pole, respectively. Under this state, the directions of φ 1 , φ 2 , and φ 3 are the directions of the arrows in the figure, and the movable iron core 9 is attracted to the permanent magnet 7 side by the attractive force of the permanent magnet 7 and the exciting current of the exciting coil 6. has been done.

Next, φ 2 becomes 0 just before an abnormality occurs in the main power supply and the current flowing through the exciting coil 6 reverses.
Due to φ 1 and φ 3 , the movable iron core 9 continues to be a permanent magnet 7.
It is attracted to the side.

However, once the current flowing through the excitation coil 6 starts flowing counterclockwise, the direction of φ 2 is also reversed, and φ 1 and φ 2
, and on the other hand, φ 3 also moves from the permanent magnet 8 to the center column 5a, so the movable iron core 9 separates from the permanent magnet 7 as shown in FIG. 5 and is immediately attracted to the permanent magnet 8 side, and once attracted Once it is done, the rest is φ 2
Even if the current flowing through the excitation coil 6 is stopped and φ 2 becomes 0, the moving iron core 9 continues to be moved by the permanent magnet 8 due to φ 1 and φ 3 .
It continues to be attracted to the side. Therefore, the arc-proof metal 15 at the tip of the movable electrodes 16, 16' attached to the movable iron core 9 comes into contact with the contact plate 22 of the backup power source, and the main power source is switched to the backup power source.

このような構造、作動状況をみてくれば以下の

First, since there are fewer mechanical components, the probability of failure is naturally reduced, making it extremely reliable. Furthermore, since the permanent magnets 7 and 8 are fixed, and according to the above embodiment, it is the fixed cores 12 and 12' that actually come into contact with the movable core 9, the permanent magnets 7 and 8 are not damaged by the shock. do not have.

Further, since the contact surfaces of the fixed cores 12 and 12' that come into contact are tapered, the contact area is large, and the movable core 9 can be attracted more reliably. Moreover, since the movable core 9 is provided close to the lower part of the excitation coil 6 wound around the center column 5a of the approximately M-shaped excitation solenoid core 5, so-called magnetic flux leakage is small and the effectiveness is high. The time required to switch from the main power source to the standby power source is also extremely short. Also permanent magnet 7,
Magnetic flux approaching and opposing the permanent magnets 7, 8
Since the current flows to the magnet 8 for only a moment, the permanent magnets 7 and 8 are hardly demagnetized.

Furthermore, when the movable iron core 9 is attracted, the attraction force is due to both the permanent magnets 7 and 8 and the exciting current flowing through the exciting coil 6.
The current consumption required by the excitation coil 6 can also be reduced.
Moreover, in the above embodiment, the structure of the current flowing through the exciting coil 6 (not shown) is changed so that the movable iron core 9 is attracted by the attractive force of only the permanent magnet 7 during normal operation, and only when an abnormality occurs. If a counterclockwise current is caused to flow through the excitation coil 6, the current consumption required by the excitation coil 6 can be further reduced. Regarding the contact points, in the above embodiment, the movable electrode 16 is pivotally mounted via the wipe spring 14, so that the shock at the time of contact is alleviated.

Furthermore, it goes without saying that the effect of this invention can be obtained even if the number of contacts is two and the conductive part is connected to the movable electrodes 16, 16' by a braided wire.
