| 摘 要： | 笔者在实验室对真空开关灭弧室真空度停电测量新方法"发射电流衰减法"和在线检测新方法"屏蔽罩磁控放电法"进行了实验研究。结果表明:"!在将真空开关的真空间隙调整为0.8 mm的小间隙以后,不需要施加磁场,使用发射电流衰减法可以停电测量灭弧室内的真空度;#"研制出具有良好内外绝缘的励磁线圈以后,使用磁控放电法能以6×10-2 Pa的灵敏度在线检测真空开关真空度。 |

| Abstract: | Two new methods were researched experimentally for on-site and on-line measurement of vacuum degree in vacuum interrupters.The experimental results show that: ①the emission current decay method can be used to determine vacuum degree on-site without imposing magnetic field while the vacuum gap distance is adjusted to 0.8 mm;②the magnetron method can be adopted to sensitively detect the vacuum degree on-line in 6×10-2 Pa if an excitation coil with favorable insulation structure is available. |
