随着现代高压电气设备的应用和局部放电给供电系统带来的危害,提出一种局部放电在线监测系统。对此,本文结合局部放电原理及局部放电检测技术的基础上,提出一种基于超声波和超高频的局部放电检测方法;其次,结合上述的监测技术,对局部放电检测系统的整体架构进行设计;再次,重点就超声波检测和超高频检测硬件电路模块进行设计;最后,利用CCS3.3软件对下机位程序进行设计和调试,利用Labview软件对上机位检测界面进行设计,并通过运行,验证了上述方案的可行性可正确性。而通过该系统设计,也为高压电气设备智能监测提供了参考。

With the application of modern high-voltage electrical equipment and the harm caused by partial discharge to the power supply system, a partial discharge on-line monitoring system is proposed. In this paper, based on the principle of partial discharge and partial discharge detection technology, a partial discharge detection method based on ultrasonic and ultra high frequency is proposed. Secondly, combined with the above monitoring technology, the overall structure of the partial discharge detection system is designed Finally, the CCS3.3 software is used to design and debug the lower part of the program, and the upper screen detection interface is designed and run by Labview software, and the design of the circuit is carried out by using the CC37 software. , Verify the feasibility of the above program can be correct. And through the system design, but also for high-voltage electrical equipment,intelligent monitoring provides a reference.
