真空バルブの開極時、並行磁界を付与すると、遮断能
力が向上するのは、周知であるが、地上設置変電所用と
いう背景もあつて、コンパクト化に対する考慮がなされ
ていないため、並行磁界用電源を別に設けていた。It is well known that the application of a parallel magnetic field when opening a vacuum valve improves the shut-off capability. However, because of the background for substations installed on the ground, no consideration has been given to compactness. Was provided separately.
本発明の目的は、小形軽量化を図り、電車床下に搭載
可能なコンパクトで大容量の直流真空遮断器を提供する
ことにある。An object of the present invention is to provide a compact, large-capacity DC vacuum circuit breaker that can be mounted under the floor of a train with a small size and light weight.

ルへの配線を代用することも可能である。The vacuum valve is opened by exciting the vacuum valve repulsion coil. Further, the commutation switch is also opened by exciting the repulsion coil for the commutation switch. At this time,
In the vacuum valve, the commutation current passing through the commutation switch flows in a direction opposite to the main circuit, so that the main circuit is shut off. Therefore,
When a commutation current flows, that is, when the excitation coil of the commutation switch is excited, it is sufficient that a parallel magnetic field is generated in the vacuum valve.Therefore, the excitation coil of the commutation switch and the parallel magnetic field coil should be connected in series. Good. In the above example, a dedicated parallel magnetic field coil is provided, but it is also possible to substitute the wiring to the commutation switch excitation coil.

ことが出来る。As a result, the vacuum valve 1 is opened and the commutation switch 6 is opened.
Closes. By this commutation switch 6 is closing, the commutation current I C shown in FIG. 3 flows through the main circuit and reverse. At this time, if the commutation switch repulsion coil 7 and the parallel magnetic field coil 4 are connected in series to the commutation command power source 5 as shown in FIG. 1, the shutoff capability in the vacuum valve 1 can be improved. Can be done.
