摘要
配电变压器故障状态的可靠性评估,对保障设备安全可靠运行、避免生产安全事故具有重要意义.本文基于配电变压器漏油故障实验数据,提出了一种考虑漏油故障的配电变压器可靠性评估方法.首先,提出了配电变压器漏油故障实验方案,获取不同状态下的变压器油压、油位和温度数据;其次,根据实验数据,从机理上构建可靠性评估模型,拟合出变压器漏油状态的变化特征曲线;最后,比对变化特征曲线与温度和压力的规律,来进行配电变压性的可靠性评估.通过实验环境与现场实例应用,所得结果表明本文可靠性评估方法具有可行性,能降低配电变压器的故障发生率,提高运行可靠性.
Abstract
The reliability assessment of the fault status of distribution transformers is of great significance for ensuring the safe and reliable operation of equipment and avoiding production safety accidents.This article proposes a reliability evaluation method for distribution transformers considering oil leakage faults based on experimental data.Firstly,an experimental plan for oil leakage faults in distribution transformers was proposed to obtain transformer oil pressure,oil level,and temperature data under different states;Secondly,based on experimental data,a reliability evaluation model is constructed from a mechanistic perspective to fit the characteristic curve of transformer oil leakage state changes;Finally,compare the variation characteristic curve with the laws of temperature and pressure to evaluate the reliability of distribution transformer performance.Through experimental environments and on-site examples,the results show that the reliability evaluation method proposed in this paper is feasible,can reduce the occurrence rate of faults in distribution transformers,and improve operational reliability.
