基于声学成像的GIS机械故障带电检测系统
|
摘要
气体绝缘全封闭组合电器(GIS)是电力系统中最重要的设备之一,机械故障是其主要故障类型之一,因此GIS机械故障诊断对于提高电力系统的安全性和可靠性具有十分重要的意义。传统的振动信号分析法是通过在GIS的壳体上测量振动来检测诸如触头异常等机械故障,但振动信号一般只进行个别位置测量,难以全面反映设备的机械状况。文中搭建了适用于GIS声场测量的声成像系统,使用具有方向性的声强探头组成阵列测量设备外壳的声场分布,试验验证了该系统的性能,为基于声学成像的GIS机械故障带电检测技术打好基础。对于提高GIS设备安全稳定运行具有十分重要的意义。
Gas-insulated switchgear(GIS) is one of the most important equipment in power system. Mechanical fault is one of its main fault types. Therefore,GIS mechanical fault diagnosis has very important significance for improving the safety and reliability of power system. The traditional vibration signal analysis method detects mechanical faults by measuring vibrations of single point on the shell which is difficult to fully reflect the mechanical condition of the device. This paper builds an acoustic imaging system suitable for GIS sound field measurement. It uses a directional sound intensity probe to compose the sound field distribution. The performance of the system is verified by the test,and a good foundation is provided for GIS mechanical fault detection technology based on acoustic imaging. It is of great significance to improve the safe and stable operation of GIS.
