| 摘 要： | 局部放电的原因是因为在外施电压作用下，静电荷会在电场中绝缘较弱的位置发生静电游离。这种脉冲型放电可引起绝缘劣化，进而导致变压器发生故障。文中提出了一种基于FPGA＋DSP的GIS局部放电在线检测系统。该系统由FPGA控制数据的采集和存储，然后利用DSP进行嵌入式TCP／IP设计，从而使采集到的信号通过以太网传输到远程PC进行显示，经现场运行测试，该系统实现了设计目标。 |

| Abstract: | The main reasons for transformer partial discharge(PD) is that electrostatic charge would dissociate at the position with weak insulation performance through the extraneous voltage.This pulse discharge type can cause insulation degradation,and even cause transformer faults.We propose an on-line system of partial discharge based on FPGA+DSP.In the system,FPGA plays the part of data acquisition and storage,and DSP performs TCP/IP embedded design,so that the data acquired can be passed by the Internet to computers to display.On-the-spot testing shows that the system realizes the goal of design. |
