110～500kV主变压器油温表运行缺陷的检测与维护策略
Detection and Maintenance Strategies for Operational Defects of Oil Temperature Gauge of 110～500 kV Main Transformer
摘要
Abstract
Oil temperature gauge can monitor temperature of transformer oil in real-time at the moment of transformer running,whether it runs normally or not decides reliability of on-line monitoring on transformer oil temperature and effective or invalid guidance for correct startup of the cooling system of transformer.Thus,it is important to detect operational defects of the transformer oil gauge.Special detection and research on operational defects of the oil temperature gauges of 110 ～500 kV main transformers in Guangzhou region were developed in aspects of voltage class,defect parts,operation time,manufacturers,and so on.Results indicate that there are different operational defects in winding oil temperature gauges and oil face oil temperature gauges,and probability of occurrence of defects are concerned with voltage class,operation time and manufacturers.A few pieces of advices for operational maintenance of the oil temperature gauge are proposed in aspects of planning design,material purchase,engineering construction,maintenance and repair and retired scrap.关键词
