摘　　要：针对智能电网建设和运行维护过程中的局部放电问题,设计了一套便携、实用的监测系统——UHF局放在线监测仪,它对传统工控机架构加以革新,通过对双路正交下变频器、双通道高速AD等技术的应用,以达到对300 MHz^3 200 MHz频段的信号进行接收、处理,具有良好的信噪比。现场实验表明,该方法的成功应用将有助于推动电力变压器局部放电检测理论和技术的发展,提高绝缘诊断的准确性和可靠性。For the partial discharge in the process of the smart grid construction and operation maintenance problems, this paper designed a set of portable and practical monitoring system — UHF partial discharge on line monitor. In order to achieve the 300 MHz to 3 200 MHz band signal receiving and has the good signal- to- noise ratio, it improves the traditional architecture, using the tech-nologies such as dual orthogonal frequency conversion, two- channel high speed AD, and so on. Field experiment shows that the successful application of this method will help to promote the development of power transformer partial discharge detection theory and technology, improve the veracity and reliability of insulation diagnosis.
