| 摘 要： | 基于即插即用思想研制了一套变压器多参量综合在线监测系统。该系统能够在统一的软硬件结构下动态添加删除监测对象和监测参量而无需对系统本身进行改动,方便地扩展为多个变电站、多台变压器的综合在线监测网络;能够实时监测变压器中性点局部放电、局部放电超高频信号、油色谱、铁芯接地电流和顶层油温等状态参量。应用该系统对330 kV变压器进行现场连续在线监测,数据显示局部放电和油色谱数据能够同时反映变压器内部局部放电变化,局部放电超高频对单次局部放电监测具有较高灵敏度,铁芯接地电流在正常范围内波动,顶层油温处于正常范围。表明该系统能够及时全面反映运行变压器绝缘状态。 |

| Abstract: | Based on plug and play concept,an integrated multiple parameter condition monitoring system for power transformer was developed.Additional monitoring equipment can be added into the system easily and the system has the expandability of monitoring multiple power transformers in different substations from different regions.Five parameters,namely radio frequency partial discharge(PD),ultra-high frequency partial discharge,dissolve gas in oil,core grounding current and top oil temperature,can be monitored by th... |
| Keywords: | power transformer online monitoring play and plug partial discharge |
