变压器早期故障在线监测装置的应用

Application of Transformer Early Failure On-line Supervisory Equipment

变压器早期故障在线监测装置是实现变压器状态维修技术的一个关键设备 ,其中变压器油色谱分析是检验变压器设备故障较成熟和有效的方法 ,但它也存在一些不确定的因素 ,要依靠实践不断取得经验。苏州供电局在所辖的 2 1个 2 2 0kV变电所中安装了智能型变压器早期故障在线监测装置 ,几年的运行取得了一定的经验 ,对此 。

The transformer early failure on line supervisory equipment is a key apparatus to realise transformer state maintenance technique,in which,the spectrum analysis method of transformer oil is a mature and effective method to determine transformer failure. But there are some undeterined facter affecting the diagnosis results,it is necessory to get more experiences by practice. A lot of intelligent transformer early failure on line supervisory equipments are installed in twenty one 220 kV substations of Suzhou Bureau of Power Supply,during some years operation, many experiences has been gotten,for which the analysis are carried out.
