【摘要】 超声波法在检测高压电器设备局部放电时存在一些弊端,为了消除或尽量避免这些问题,笔者阐述了光纤传感器的原理及其用于高压电器设备绝缘监测的依据,介绍了基于Fabry-perot、Mach-zehnder和Michelson 3种干涉原理的光纤传感器及其在高压电器设备局部放电超声-光检测中的试验研究和实际应用,最后提出了高压电器设备局部放电超声-光检测法研究目前存在的问题及发展方向。试验和实际运用研究表明,利用光纤技术实现的超声-光检测和定位局部放电实现高压电器设备绝缘监测是完全可行的。更多还原

【Abstract】 The ultrasonics method has shown some drawbacks in detecting high-voltage equipment PD.In order to eliminate or aroid these problems,the author introduced the principle of optical fiber sensor,the fitness of its application to high voltage equipment insulation monitoring and test,and the practical application of three kinds of optical fiber sensors based on Fabry-perot,Mach-zehnder and Michelson interferometries to high voltage equipment.The outstanding problems are put forward,and the development tendency of the acousto-optical partial discharge detection for high voltage equipment is forecasted.Testing and practical application research shows that the use of acusto-optical detection and loation of PD which realized by the fiber-optic technology to achieve high voltage electrical equipment insulation monitoring is entirely feasible.更多还原
