箱式变电站的影响温升试验判定因素探究

Investigation on the Factors Determining the Temperature Rise Test of Box-type Substation

箱变的温升试验是检测箱变的运行过程中组成箱变的各个电力设备可靠性的一项重要的测试试验,温升试验判定的有效性显得尤为重要。温升试验是否合格分为温升试验过程和温升结果数据两个阶段的判定,以常见欧式箱变内用油浸式变压器为例,用2个独立电源分别在高压侧和低压侧进行连续通电,采用短路法达到热平衡。本文针对这两个阶段影响判定结果的因素进行分析。

The temperature rise test of box-type substation is an important test t to detect the reliability of each power equipment composed of box-type substation during the operation of box-type substation,and the effectiveness of temperature rise test judgment is particularly important.Whether the temperature rise test is qualified,that is divided into two stages:the temperature rise test process and the temperature rise result data,and this paper analyzes the factors that affect the judgment in these two stages.
