变压器故障在线监测的一种方法

A method of online monitoring of transformer fault

变压器油中气体在线监测技术是以油中溶解气体为监测对象,应用该技术可及时掌握变压器的运行状况,发现和跟踪存在的潜伏性故障。配合计算机系统对故障进行诊断,可以避免部分灾难性事故,实现状态检修、降低维护成本、提高自动化程度,提高变电站运行管理水平。使用开源软件开发了在线监测软件,该软件具有模块化及安全、灵活的数据库操作和跨平台特性,经实验检验达到了设计的目标。

The monitoring technology of gas in oil in the transformer takes the dissolved gases in oil as the monitoring object. The operating condition of the transformer can be monitored timely to discover and track the presence of latent failures. Some catastrophic accident can be prevented with the computer system fault diagnosis, realizing condition-based maintenance, reducing maintenance costs and increasing the degree of automation and improving operational management of the substation. Online monitoring softwareis developed using the open source software, which is modular, has secure, flexible database operations and cross-platform features.The experiment showed that it can satisfy the design goal.
