Oil Leakage Detection Technology of Casing Based on Relatively Infrared Imaging and Temperature Difference Criterion

摘要: 变压器套管在运行过程中时常会因各种各样的原因产生渗油现象，传统的油位检测方法效率低且准确率无法保证，为了及时发现并采取解决措施，为此提出一种基于相对温差判据的红外成像套管漏油检测方式。该方式在红外成像的基础上，结合温度判据和套管故障面积，能够准确判断是否漏油以及漏油程度，提醒运维人员及时发现问题并采取相应的措施，以保证变压器的正常运行。

Abstract: During the operation of the transformer bushing, oil leakage often occurs for a variety of reasons. The traditional oil level detection method is inefficient and the accuracy cannot be guaranteed. In order to find out and take corrective measures in time, a temperature difference based on this is proposed. We use the criteria for infrared imaging casing leak detection methods to illustrate. Based on the infrared imaging, combined with the temperature criterion and the casing fault area, this method can accurately determine whether the oil leakage and oil leakage degree, remind the operation and maintenance personnel to find the problem in time and take corresponding measures to ensure the normal operation of the transformer.
