| 摘 要： | 通过设计一款变压器局部放电的超高频监测系统，将微弱的超高频信号放大到足够的幅度，采用多级滤波去除带外干扰，以便于对传输线路所采集到的超高频信号进行处理与分析，并利用Lab-VIEW软件仿真与虚拟分析，对电力系统变压器的故障进行早期诊断，对变压器早期产生病变以及发展趋势发出预警，以确保电力系统变压器安全、可靠地运行。

| Abstract: | A transformer partial-discharge ultra-high enlarge UHF signals. A multi-band filter was adopted to facilitate the process and analysis of UHF signals frequency monitoring system was designed to to remove out-of-range frequency interference acquired by the transmission line. The Lab- VIEW software simulation and virtual analysis were also employed to make early diagnosis of power transformer faults and to make warning of transformer early lesions and development. |
