一起10kV侧主变套管过热及漏油故障的诊断

Diagnosis of an Overheat and Oil-leakage Fault of 10 kV Main Side Transformer Bushing

红外诊断技术能快速实时地在线监测和诊断电力设备的大多数故障,能及早发现设备缺陷,以提前采取措施,防止设备出现故障造成停电,是电力设备带电条件下进行状态检测的有效手段之一。介绍了一例通过红外诊断技术及时发现的主变10 kV套管过热故障,通过对该故障的诊断分析,避免了设备故障的扩大。

The infrared diagnostic technology, which can be used rapidly and in real time to realize the on-line monitoring and diagnosis of most power equipment faults, can early detect equipment defects for taking measures in advance to prevent the power outages caused by equipment malfunction, so, it is one of the effective measures of making the state inspection of power equipment under the charged condition. This paper introduces an overheat and oil-leakage fault of 10 kV main side transformer bushing that was found in time through infrared diagnostic technology. The expanding of the equipment fault was avoided through the diagnosis and analysis on the equipment fault.
