重大な支障をきたす。2. Description of the Related Art There are two types of electrification methods for electric railways, an alternating current feeding method and a direct current feeding method. It may be. In such a case, conventionally, a dead section is provided at the boundary between the AC feeding section and the DC feeding section, and when the train passes between these sections, the electric vehicle is coasting. However, if the train stops in the dead section for some reason, it will not be able to run on its own and will seriously hinder train operation.

AC-DC switching section 3 is provided between the DC and DC feeding section 2, and AC switching switch 4 and AC-DC switching section switch 7 using a GTO thyristor or the like are used to alternately open and close these. By doing so, a feeding system is conceivable in which the electric vehicle 6 can be restarted even if the electric vehicle 6 stops in the AC / DC switching section 3.

に多くなると言う欠点があった。The AC / DC switching section switch 7 is opened / closed each time the electric vehicle 6 passes, so that it can be opened / closed frequently, and it has the ability to open / close a DC current at the same time. However, a static switch using a GTO thyristor is considered. However, an AC feeding voltage is simultaneously applied to this switch, and this AC feeding voltage is generally 20 to 30.
Since it is as high as KV, there is a drawback that the number of elements in series in a static switch is very large.

An AC / DC switching switch which is connected via a switching switch and is configured by arranging an AC / DC switching section and a DC feeding section in series with a high-voltage switching section and a DC voltage interruption section. It is configured by connecting via.

直流電流遮断部５２より構成されている。In the figure, reference numeral 1 is an AC feeding section in which AC is supplied at AC of 20 KV, and 2 is a DC feeding section in which DC is supplied at DC 1500 V. In the meantime, an AC feeding section 1 and a DC feeding section 2 are provided. An AC / DC switching section 3 is provided for switching between. The AC feeding section 1 and the AC-DC switching section 3 are connected via the AC switching switch 4,
The AC / DC switching section 3 and the DC feeding section are connected via an AC / DC switching switch 5. The switching switch 5 for the AC / DC switching section has a high-voltage switching unit 51,
It is composed of a direct current interruption unit 52.

されている。Now, the electric car is DC1 which is the DC feeding section 2.
A case of entering the AC20KV section which is the AC feeding section 1 from the 500V section will be described. If the electric vehicle is in the DC feeding section 2, AC / DC switching section switching switch 5
The high-voltage switching unit 5 and the DC blocking unit 52 are both in the conductive state, and 1500V DC is supplied to the AC / DC switching section 3.

ことはない。When the electric vehicle enters the AC / DC switching section 3, first, the DC current supplied to the electric vehicle is interrupted by the DC interruption unit 52, and then the high voltage switching unit 51 is opened in a no-load state. Therefore, the AC-DC switching section will bear a blackout. After that, the AC switching unit 4 is turned on, the AC-DC switching section 3 is pressurized by AC20KV, and the AC is applied to the electric vehicle.
Power of 20 KV is supplied. On the other hand, in the AC / DC switching section switching switch 5, since the high voltage switching unit 51 is opened, AC20KV is not applied to the DC current interruption unit 52.

る。When the electric vehicle enters the AC feeding section, the AC switching switch 4 is opened, and the AC-DC switching section is out of service. After that, the high-voltage switching unit 2 is turned on, and then the DC current interrupting unit 3 is turned on, so that the AC / DC switching section is again pressurized to DC 1500V and prepared for the next train.

流−直流切替区間用切替開閉器５が可能となる。Therefore, since only a voltage equal to the DC feeding voltage is applied to the DC blocking unit 52 and is not affected by the AC feeding voltage at all, the number of series elements such as GTO thyristors used in the DC blocking unit 52 is reduced. The switching switch 5 for the AC / DC switching section can be significantly reduced and can be economical.

部を低耐圧のものを使用可能となる。As described above, according to the present invention, the high voltage switching unit is opened while the AC power is being supplied to the AC / DC switching section, so that a high AC voltage is applied to the DC voltage cutoff unit. Since no voltage is applied when the voltage is applied, it is possible to use a DC voltage cut-off unit having a low withstand voltage.
