摘要
对变压器的在线监测主要由该变压器油中气体的变化、局部放电监测、油中水分监测、绕组热点温度的监测这4部分构成,而目前大部分变压器的在线监测技术是对单一设备的性能指标进行监测,而要通过单一数据反映变压器的性能具有很大的局限性。而数字化变电站的在线监测系统采用一体化技术,使各个有效数据均能进行监测,克服单一数据问题。
The main job of transformer online monitoring is to monitor gas variety in the tank, partial discharge, moisture content in the oil, and coiling hot-point temperature. So far the most transformer online monitoring technologies gain indexes from single device, and it can not easily find the whole running situation of transformer via single data set. This digital substation online monitoring system adopted integrated technology, and qualitative data can be monitored effectively.
