摘要
作为电力系统的关键设备之一,10 kV开关柜的稳定运行对保障电网的安全性与可靠性十分重要。局部放电是一种常见的电气设备绝缘缺陷表现形式,会显著降低电气设备的绝缘性能,甚至引发电气故障甚至事故,威胁电力系统的稳定运行。因此,准确检测并分析10 kV开关柜中的局部放电,对保障电网运行的安全性和可靠性具有重要意义。文章综合探讨10 kV开关柜局部放电的基础理论、检测技术及其数据分析方法,包括射频识别(Radio Frequency Identification,RFID)检测技术、无线传感网络以及包括傅里叶变换和小波变换的信号处理技术,并通过技术测试验证这些方法在实际应用中的有效性和准确性。
As one of the key equipments of the power system,the stable operation of 10 kV switchgear is very important to ensure the safety and reliability of the power grid.Partial discharges are a common form of insulation defects in electrical equipment,which can significantly reduce the insulation performance of electrical equipment and even cause electrical failures or even accidents,threatening the stable operation of the power system.Therefore,accurately detecting and analyzing partial discharges in 10 kV switchgear is of great significance to ensure the safety and reliability of power grid operation.The article comprehensively discusses the basic theory of partial discharge in 10 kV switchgear,detection technology and its data analysis methods,including Radio Frequency Identification(RFID)detection technology,wireless sensor network and signal processing technology including Fourier transform and wavelet transform,and verifies the effectiveness and accuracy of these methods in practical application through technical tests.The effectiveness and accuracy of these methods in practical applications are verified through technical tests.
