し、電流遮断が不能になるという欠点があつた。Generally, a DC circuit breaker has a capacitor and a reactor, that is, an LC resonance circuit, connected in parallel with a circuit breaker, for example, a vacuum circuit breaker. At the same time as opening the vacuum circuit breaker, a direct current is passed through the LC resonance circuit, an alternating current is passed through the vacuum circuit breaker, and the electrodes of the vacuum circuit breaker cut off at the current zero point. When a large DC current flows through the LC resonance circuit, unless the vacuum circuit breaker is opened for a short time, the large DC current increases with time, which makes current interruption impossible.

Japanese Patent Laid-Open No. 064 proposes a vacuum circuit breaker and a circuit breaker in which a current is caused to flow through an electromagnetic repulsion coil and is interrupted by electromagnetic forces in a mutually repulsive direction generated by a current induced in a short-circuit plate.

Move to bellows, melt bellows,
It was impossible to improve the breaking performance.

本発明の目的は、アークが電極以外に点弧するのを防止

ある。An object of the present invention is to provide a vacuum circuit breaker in which an arc is prevented from being ignited other than the electrodes and the breaking performance is improved.

るので、しや断性能を向上させることができる。When a direct current is passed through the electromagnetic repulsion coil, magnetic flux is generated.
When the magnetic flux passes through the short-circuit plate, an eddy current is generated. The magnetic flux due to the eddy current and the magnetic flux on the electromagnetic repulsion coil side collide with each other.
The electromagnetic repulsive force at the time of collision causes the short-circuit plate and the movable rod to move at a high speed in a direction away from the fixed electrode. During this period, the arc is ignited between both electrodes, and the magnetic flux from the electromagnetic repulsion coil continues to apply the parallel magnetic field to the arc, which prevents the arc from moving to other than the electrodes. The performance can be improved.

することができる。Next, the alternating current from the alternating current power supply unit 21A is rectified by the diode 24 into direct current, and the direct current charges the capacitor 26. When a current transformer (not shown) detects a short-circuit current flowing through the main circuit conductor 10 in this state, the switch 25 is closed. Then,
The discharge current from the capacitor 26 flows through the electromagnetic repulsion coil 17. The electromagnetic repulsion coil 17 has a magnetic flux Φ C shown in FIGS. 2 and 3.
And the magnetic flux Φ C passes through the short ring 16. The eddy current I induced by the short ring 16 flows, and the magnetic flux Φ C
And a magnetic flux Φ S in the opposite direction is generated. Both magnetic fluxes collide with each other, and the electromagnetic repulsion force at this time causes the shuttle ring 16 to move in the direction of the arrow X 2 , causing the electrodes to separate and generate an arc. The magnetic fluxes Φ C and Φ S work in a parallel magnetic field in the arc, but the magnetic flux Φ S
Moves in a direction away from the arc, so that the magnetic flux Φ C mainly acts on the arc as a parallel magnetic field. As a result, although the electromagnetic repulsion coil 17 is used to separate the movable electrode 7 from the fixed electrode 6 at a high speed, the arc is surrounded by the parallel magnetic field, so that the arc does not move to a portion other than the electrode. It is possible to improve the cutting performance. In particular, in order to improve the breaking performance, if the chute ring and the electromagnetic repulsion coil are arranged outside the vacuum container corresponding to the electrodes, the parallel magnetic field is strengthened and the breaking effect is great. Further, since the parallel magnetic field is applied to the arc, the breaking performance can be further improved.

この実施例では、平行磁界が発生するために、平行磁界
用コイルを別個に設けることなく、電磁反撥コイル17を

る。In this embodiment, since the parallel magnetic field is generated, the electromagnetic repulsion coil 17 is used without separately providing the parallel magnetic field coil, so that the structure can be downsized.

い。Further, in order to adjust the increase or decrease of the magnetic flux Φ S , in the present invention, if any one of the taps 22C is selected as the switch 23,
Since the direct current flowing through the electromagnetic repulsion coil 17 can be increased / decreased, the magnetic flux can be adjusted in accordance with the breaking capacity. In this case, it goes without saying that the same taps may be used when used for a plurality of vacuum circuit breakers having the same capacity.

ることができる。On the other hand, since the capacitor 26 is used in this embodiment, the magnetic flux Φ G acting between both electrodes attenuates with the passage of time as shown in FIG. For this reason, the arc is also gradually attenuated as time t passes, and the breaking current level current can be reduced.

更に、本発明の真空遮断器は直流遮断器および閉鎖配電
盤に使用できることは勿論である。Furthermore, the vacuum circuit breaker of the present invention can of course be used in DC circuit breakers and closed switchboards.
