从真空开关上不拆卸真空灭弧室测量其真空度的机理研究

Study on Mechanism for the Undetached Measurement of Internal Pressure of Vacuum Interrupters

应用新型励磁线圈测试了真空灭弧室磁控放电的着火条件， 以及离子电流与真空度的关系， 并从理论上探讨了不拆卸真空灭弧室测量其真空度的磁控放电机理。

The critical initiation condition of magnetron discharge as well as the relationship between internal pressure and ion current in vacuum tube are measured by a new type coil,and the mechanisms of the magnetron discharge in the undetached measurement of internal pressure of vacuum interrupters are studied
