Although the vacuum switch tube is constructed as shown in FIG. 2, the withstand voltage performance between the electrode 3 and the shield 5 may not be sufficient for use as a high voltage switch as is. Therefore, it is necessary to improve the withstand voltage performance by conditioning it. A conventional device for performing such conditioning has an AC power source 2 connected between an electrode 3 of a vacuum switch tube 1 and a shield 4, as shown in FIG.
As a result, a voltage higher than the withstand voltage between the shield 4 and the electrode 3 is applied, and a vacuum arc is generated between the shield 4 and the electrode 3. At this time, the surfaces of the shield 4 and the electrode 3 are cleaned by the arc heat, and the withstand voltage performance between the shield 4 and the electrode 3 is improved compared to before the vacuum arc is generated. The conditioning of the vacuum switch tube is completed by the above operations, but after conditioning, a film of the material of the shield 4 is formed on the surface of the electrode 3.
A film of the material of the electrode 3 is formed on the surface of the shield 4.

When a voltage of negative polarity higher than the withstand voltage performance between the shield 4 and the electrode 3 is applied between the shield 4 and the electrode 3 from the single polarity power supply 22 connected as shown in the figure, the shield 4 and the electrode 3 An arc discharge occurs in a vacuum between the The surfaces of the shield 4 and the electrode 3 are cleaned by the arc heat generated by the arc discharge in vacuum, and the voltage resistance between the shield 4 and the electrode 3 is improved compared to before the vacuum arc is generated. This makes it possible to condition the vacuum switch tube in the same manner as in conventional devices.
Also, in this invention, a single polarity power supply is used,
In addition, since a negative voltage is applied to the shield side, a film of the material of the electrode 3 is not formed on the surface of the shield 4 after conditioning, but a film of the material of the shield 4 is formed on the surface of the electrode 3. will be formed. Therefore, the withstand voltage performance after conditioning between the shield 4 and the electrode 3 is determined by the material of the shield 4, and since the shield 4 is usually made of a material with high withstand voltage capacity, the withstand voltage strength is determined by the material of the shield 4. You can get a high vacuum switch tube.
