摘要
针对乌海电业局电流互感器绝缘油现场取样时步骤繁琐、耗时长,且无法实现全密封取样,导致绝缘油色谱试验分析误差大的问题,通过优选制造材料,应用螺纹力学,在原电流互感器顶珠式取样阀基础上,研制了取样阀转接装置与其配合取样。采用该转接装置后可降低取样难度,缩短取样工作时间,将取样时间由35min缩短至14min,大幅提高了现场绝缘油的取样工作效率。同时采用取样阀转接装置取得的油样进行绝缘油色谱分析,所得的数据准确性更高,更能准确地反映电流互感器的运行状态。
In order to solve the problem of large error in chromatographic test and analysis of insulating oil of current transformer in Wuhai Electric Power Bureau,due to the cumbersome and time-consuming steps of field sampling and the failure of fully sealed sampling,a sampling valve adapter is developed based on the original top-bead sampling valve of current transformer by optimizing the manufacturing materials and applying threading mechanics.The device can reduce the difficulty of sampling,shorten the sampling transfer time from 35 minutes to 14 minutes,and greatly improve the efficiency of field insulation oil sampling.At the same time,the chromatographic analysis of insulating oil is carried out by using the oil sample obtained by the sampling valve switching device.The data obtained are more accurate and can reflect the operation status of current transformer more accurately.
