树状放电的CPN识别方法

Recognition of treeing discharges using CPN

电力变压器发生击穿之前会在固体绝缘材料上产生树状放电通道 .若能检测到树状放电信号 ,则可以断定变压器绝缘状况已经恶化 ,因此在线监测中对树状放电的检测具有十分积极的意义 .在实验条件下对在线监测中树状放电的识别进行了研究 .建立了变压器绕组模型和树状放电产生电路 ,模拟了在绕组不同部位发生树状放电的情况 .通过CPN型神经网络的引入 ,成功地实现了在一定噪声水平下树状放电的识别 .同时 。

Presents the trial recognition of treeing discharges under a certain level of noise background by constructing a transformer's winding model and a treeing discharge generation circuit, and simulating treeings happened at different winding sections with neural network introduced, and the recognition of treeing discharges was achieved.
