しまうという問題が生ずる。The 11ii magnetic repulsion contact device has a movable contact and a fixed contact placed in parallel with each other so that the current direction is opposite to each other, so that an electromagnetic repulsion force is applied between the two contacts, thereby reducing the risk of short circuits. A device that increases the current limiting effect by speeding up the opening of the contact (although in this type of contact device, the contact pressure of the contact in the ON state is , the biasing force of the contact spring will naturally be in the opposite direction to the opening force due to electromagnetic repulsion.For this reason, part of the opening force due to electromagnetic repulsion will be applied to the contact pressure. This causes a problem in that the electromagnetic repulsion force is canceled out by the spring, and the opening speed is reduced accordingly.

を向上することが可能となるのである。The present invention has been made in view of this point, and has been made for the purpose of providing an electromagnetic repulsion contact device that can prevent low F opening force during opening due to electromagnetic repulsion and increase opening speed. Yes, a J moving contact holding plate is attached to ρ■ moving contact support frame rotation = J function, and a contact pressure spring is interposed between this moving contact holding plate and the movable contact. In the ON state and OFF state, the movable contact holding plate is unrotatably locked to the movable contact support frame, thereby applying rotational force for contact pressure to the movable contact, and when opening due to electromagnetic repulsion, ,
It is characterized in that the urging force of the contact pressure spring is not applied to the movable contact when the lock is released. In other words, when a short-circuit current flows and the electromagnetic repulsion force starts to open the contact and the movable contact begins to move, the contact pressure spring's rotational force in the direction that prevents the contact opening is lost, so part of the opening force due to the electromagnetic repulsion is canceled out. Therefore, the electromagnetic repulsion force is fully utilized to perform pole opening at high speed, and it becomes possible to quickly increase the arc voltage and improve current limiting performance.

高速で行なわれるのである。Note that the long hole (Ila) is indicated by a chain line. Since the projecting piece (29) of the movable contactor (7) is located close to the locking recess (llb), when opening due to electromagnetic repulsion begins, j1
As shown in Figure 7fbl, the protruding piece (29) is the locking member (23)
At this time, the locking member (23) is pushed from the locking recess (llb) toward the elongated hole (lla). The play hole (21b) of the movable contact holding plate (21) is connected to the lock member (23).
) has an elongated shape that allows it to move slightly along the holding plate (21), so the lock member (23) pressed by the protrusion (29) will move as the movable contact (7) continues to rotate. Finally, it is pushed out from the locking recess (llb), and the movable contact holder 4 becomes able to move within the long space (11 m) and is unlocked.
1x (21) is the rotation - ■ function. Therefore, the presser plate (2
1) does not interfere with the opening operation of the movable contact (7) (they rotate together, resulting in the state shown in Figure 7 ([), that is, tc+ in Figure 2, and the same result is obtained as the opening force increases). Therefore, electrode opening is performed at high speed.

It is done by This presser plate reset plate (31) is fixed to the device base (1) by an appropriate means. By rotating and pushing the movable contact holding plate (21) with the holding plate reset plate (31), the holding plate (21) rotates and the locking member (23) reaches the lower end of the elongated hole (11 m). The locking member is moved to the locking recess (26) by the locking member return spring (26).

An opening spring support shaft (32) is attached to the protruding piece (29), and an opening spring (33) is suspended between the support shaft (32) and the stopper shaft (28). The support shaft (32) is
When the movable contact holder & (21) is in the locked state, it is provided so as to be located on the extension line connecting the stopper shaft (28) and the shaft pin (25), and the opening spring (33) is located on the extension line connecting the stopper shaft (28) and the shaft pin (25). (25) is in contact with the upper surface. Therefore, a clockwise rotational force is applied to the movable contact (7), but since the opening spring (33) is in contact with the shaft pin (25), this rotational force is not so large, and the contact pressure spring By slightly increasing the pressing force in (20), the necessary contact method can be ensured.

。When a short circuit current flows in the ON state and opening starts due to electromagnetic repulsion, the movable contact (7) rotates and the position of the opening spring support shaft (32) becomes higher, and the opening spring support shaft (32)
), the shaft pin (25), and the stopper shaft (28) become smaller than 180°, and the rotational force of the opening spring (33) in the direction of the hour hand increases. This rotational force is in the opening direction and increases as the opening progresses and the movable contact (7) rotates, so the opening force is caused by electromagnetic repulsion and by the opening spring (33). As a result, the opening force increases, and the synergistic effect with the disappearance of the anti-polarity force due to unlocking promotes the opening operation. Therefore, the opening speed becomes faster, and the arc liquid can be increased quickly to further improve the current limiting performance.

When opening due to electromagnetic repulsion, the lock is released so that the force of the contact pressure spring does not apply to the movable contact, and the opening force when opening due to electromagnetic repulsion is fully utilized to open the contact. This makes it possible to quickly increase the arc voltage and improve current limiting performance.
