摘要
简要介绍了变压器局部放电的内部机理,针对变压器局部放电提出了一整套切实可行的在线监测方案。通过对监测案例的分析详细论证了监测系统的可行性,充分证明了基于数字化设备的局部放电在线监测系统能够为提高变压器的故障诊断能力提供保证,具有较高的实用价值和推广价值。
The internal mechanism of the partial discharge in transformer is briefly introduced,and then a set of feasible schemes for the online monitoring of the partial discharge is put forward herein.According to the analysis on the monitoring cases concerned,the feasibility of the monitoring system is demonstrated in detail,which fully proves that the partial discharge monitoring system based on the relevant digital equipment can provide a guarantee for enhancing the capacity of the transformer fault diagnosis,and accordingly has a higher practical and promotive value as well.
