| 摘 要： | 采用了新型的比例差分双通道电场探头,通过监测真空灭弧室屏蔽罩电位和周期性高频脉冲电压,并将这两个测量值与实际电压值取比率,经过标定后,将该比率作为监测参数,来分析真空灭弧室真空度的变化趋势。现场试验表明,使用该探头可有效消除各相系统电压波动和灭弧室外围空间电场对测量精度的影响,实现有效测量,使用该方法的测量系统具有实际应用的价值,可完成真空灭弧室真空度在线监测任务。

| Abstract: | The new type proportional difference bi-channels electric field detectors can detects the development trends of vacuum level in vacuum interrupters,which makes the proportion between the voltage on the shield in vacuum interrupters and periodical high-frequency pulse voltage to be the monitoring parameter.The field testing shows that the detector can avoid the infection of periphery electric field effectively,has practical application value,and can be used for on-line monitoring of vacuum degree in vacuum interrupters. |
