摘　　要：为进一步提升电力施工现场安全检测准确率,提出高灵敏度纳米纤维光纤传感器,用于感知气体绝缘开关设备(GIS)中局部放电。实验结果表明,不同静电放电电压条件下,12 cm和14 cm长的纳米纤维检测时间均小于8 cm纳米纤维,应选择长度为12 cm的纳米纤维传感器。与水凝胶传感器相比,纳米纤维光纤传感器对局部放电信号更加敏感,最大灵敏度为120 dB,较水凝胶传感器增加26.31%。纳米纤维光纤传感器的平均检测限约为0.26 Pa,而水凝胶传感器的平均检测限为1.81 Pa,较纳米纤维光纤传感器增加591.15%。纳米纤维光纤传感器可有效识别电力设备局部放电。In order to further improve the accuracy of safety detection at power construction sites,a high-sensitivity nanofiber optical fiber sensor was proposed to detect partial discharge in gas-insulated switchgear(GIS).The experimental results showed that the detection time of 12 cm and 14 cm long nanofibers was less than that of 8 cm nanofibers under different electrostatic discharge voltages,and the nanofiber sensor with a length of 12 cm should be selected.Compared with the hydrogel sensor,the nanofiber fiber sensor was more sensitive to partial discharge signals,with a maximum sensitivity of 120 dB,which was 26.31%higher than that of the hydrogel sensor.The average detection limit of the nanofiber fiber sensor was about 0.26 Pa,while that of the hydrogel sensor was 1.81 Pa,which was 591.15%higher than that of the nanofiber fiber sensor.Nanofiber fiber optic sensors can effectively identify partial discharges of power equipment.
