| 摘 要： | 钳式Rogowski传感器在电缆局部放电检测中被广泛运用,但被测导体如果偏心穿过钳式Rogowski传感器会影响传感器的输出电压.通过实验测量,研究了被测导体通过钳式Rogowski传感器时偏心距离的大小对传感器输出电压幅值的影响,并对测量数据进行了归纳总结.由实验结果可知,导线偏心对钳式Rogow ski传感器的输出电压的幅值影响在9%以内,偏心导体靠近BNC接头侧,Rogow ski传感器的输出幅值增大,反之其输出幅值减小.

| Abstract: | An off-center conductor doesn''t go through the center of the sensor. Clamp Rogowski current sensor is widely used in monitoring the cables that have been put into operation.Clamp Rogowski sensor''s output voltage is affected by off-center conductor to be measured. The relationship between conductor off-center distance and Rogowski sensor ''s output voltage is measured and analyzed in detail in the experimentnt. From the experimental results, the influence of eccentric conductor on magnitude of Rogowski sensor output voltage is within 9%. The output amplitude of the Rogowski sensor increases when the off-center conductor is close to the joint of BNC, and decreases when it is more distant from it. |
