摘要
变电设备的状态检修是根据预防性试验、不良运行工况记录、缺陷记录、检修记录等纵向和横向的能够反映电力设备运行状态的各类数据对其状态进行综合判断,以变压器为例,对输入数据采用了统计的方法进行分析计算,解决了大量的数据统计分析判断的复杂问题,将该方法应用于状态检修的辅助决策系统中,可以实现计算机智能诊断的状态分析功能,科学地判断设备当前的运行状态,以便合理安排检修计划和检修重点。
Transformer state maintenance is according to the preventive test, the adverse operating conditions maintenance records, defect records, longitudinal and transverse record of electric power equipment running status to reflect on the status of all kinds of data on comprehensive judgement. Taking the transformers as an example, the paper adopts the input data to analyze and calculate in a statistical way. A lot of complex problems of data statistic analysis are solved. The way can be applied to the maintenance of auxiliary decision-making system. The function of computer intelligence diagnosis can be realized. The equipment running status can be judged scientifically to arrange maintenance plans and maintenance points.
