变压器用电容型套管故障简析

套管是变压器的重要组件，对保证变压器的可靠供电和安全运行至关重要。在变压器的事故和障碍统计中，与套管相关的事故和障碍也占相当的比例，并且随着电压等级的提高，所占比例不断增加。由于套管故障引起的事故，其原因多种多样，需尽可能对一定范围内的同类事故进行统计分析，找出规律。本针对变压器上大量使用的油浸电容式套管发生的故障实例，进行简要的归纳分析，并提出一些建议，可作为相关部门采取改进措施的参考。

Fault Analyses of Oil Condenser Bushing for Transformer

Bushing is the important component of transformer, and it is most important for guaranteeing safe operation and the reliable power supply of transformer. In statistics of fault and obstacle of transformer, the faults and obstacles related to bushing also take considerable proportion, and along with the raising of voltage grade, the proportion taken increases continuously. Because the reasons of faults and obstacles caused by bushing are varied, it is needed to carry out statistical analysis as far as possible for the similar faults in certain scope. This paper briefly analyzes the fault examples of oil condenser bushing for transformer, and presents some suggestions, which can be the reference of improving measures for related sectors and departments.
