一起变压器故障综合分析

Comprehensive Analysis of a Transformer Fault

当前电力系统中的薄弱环节主要集中在10 kV配电网,10 kV配电变压器又是配电网的核心设备,因此对10 kV配电变压器的生产制造要求越来越高,对其运维检测分析能力要求也越来越高。文章通过对一起10 kV配电变压器典型故障的检测分析,准确确定故障类型、找到故障位置,对当今市场上使用的变比测试仪测试原理进行介绍,同时对数据进行分析,对今后的故障分析提供经验和依据。

The weak links in the current power system are mainly concentrated in the 10 kV distribution network,and the 10 kV distribution transformer is the core equipment of the distribution network.Therefore,the production and manufacturing requirements of 10 kV distribution transformer are higher and higher,and the requirements for its operation and maintenance detection and analysis ability are higher and higher.In this paper,through the detection and analysis of a typical fault of 10 kV distribution transformer,the fault type and fault location are accurately found.The test principle of transformation ratio tester used in the market today is introduced.At the same time,the data analysis provides experience and basis for the future fault analysis.
