The vacuum switch tube is constructed as shown in Figure 2 (1), but the withstand voltage performance between the electrode (4) and the shield (5) may not be sufficient to use it as a high-voltage switch as is. be. Therefore, it is necessary to improve the withstand voltage performance by conditioning this. A conventional device for performing such conditioning is as shown in FIG.
Polarization (4) and shield (5) of vacuum switch tube (1)
A voltage higher than the withstand voltage between the shield (5) and the electrode (4) is applied by the AC power supply (2) through the resistor (3) between the shield (5) and the electrode (4). In between, the complete occurrence of wire breakage in vacuum is established. Due to this dielectric breakdown in vacuum, the ltt voltage performance between the shield (5) and the electrode (4) is improved compared to before the dielectric breakdown occurs. Therefore, by repeatedly causing this dielectric breakdown, the withstand voltage performance between the υ shield (5) and the electrode (4) can reach a withstand voltage strength corresponding to the number of breakdowns. Conditioning is thus completed. Further, the resistor (3) is used to limit the current so that more current than necessary flows through the circuit in the event of dielectric breakdown. Also, after conditioning, the electrode (4)
A coating of the material of the electrode (4) is formed on the surface of the shield (5) facing the electrode (4).
