光纤传感器在局部放电检测中的应用

Application of Optical Fiber Sensor in Detection of Partial Discharge

电力设备绝缘老化的问题可以通过局部放电在线检测的方法监测出来,以提高故障诊断的针对性。不过传感器的灵敏度及可靠性会受到现场电磁干扰的影响,因此传感器的性能就是影响检测效果的重要因素之一。本文就局部放电检测技术中光纤传感器的应用展开讨论,提出光纤传感器用于局部放电检测中的试验及验证结果。

The electric power equipment insulation aging problem through partial discharge on-line detection method of monitoring and fault diagnosis has improved the pertinence. However, the sensitivity of the sensor and the reliability can be affected by the electromagnetic interference effects, thus the performance of the sensor is one of the important factors that influence the detection effect. Based on the partial discharge detection technology in the application of the optical fiber sensor is discussed and proposed fiber sensor for partial discharge detection in test and verify the results.
