摘要：
牵引变压器是牵引供电系统的重要组成部分之一,监测牵引变压器运行状态,及时地发现牵引变压器内部故障,对于确保高速铁路安全运行具有重要的意义。dga技术是检测变压器潜伏性绝缘故障的有效措施之一。文章基于dsp技术,设计了一套牵引变压器dga在线监测系统,经过实验室多次模拟试验,系统数据理想可靠。

abstract: traction transformer is one of important components of the traction power supply system.since inner fault may be found easily by on-line monitoring for traction transformer,it is very important for safety of high-speed railway.dga(dissolved gas-in-oil analysis) is an effective technique to detect the running state of transformers.in this paper,on-line monitoring system for traction transformer was designed by using dsp technology.
