单片机变压器故障诊断系统设计.pdf

[摘要] 大型电力变压器是电力系统中重要的和昂贵的设备之一，其运行状态直接影响系统的安全性。目前，

电力系统的检修体制正由定期检修向状态检修转变，而状态检修是以了解设备的运行状态为基础的。要了解设备状

态，就需要对设备信息进行分析诊断。本文的工作就是在这一背景下开展的，其意义在于为电力变压器的检修提供

技术支持。本文是从变压器的故障原因、类型以及分析入手，设计了基于单片机的变压器故障诊断系统。

being changed from periodical maintenance to state repair, which is based on understanding the operation state of the

equipment. To understand the state of the device, the device information needs to be analyzed and diagnosed. The work of

this paper is carried out in this background, its significance is to provide technical support for power transformer overhaul.

In this paper, a transformer fault diagnosis system based on single chip is designed based on the fault reason, type and

analysis of transformer.

In the hardware part of the system, based on AT89C52 single chip microcomputer as the core, sensor will be collected,

such as voltage, current, temperature and gas analog signal is converted to A digital signal after A/D converter, and then into

the microcontroller in the system after processing, by processing the results to determine whether the transformer containing

fault and the fault type and so on, and then through the human-computer interaction interface display.
