摘要
结合电网设备状态检修和带电检测工作中开展在线监测装置和便携式检测装置检验的需求,在深入研究变压器油标准样品配制方法的基础上,研制出一套集"定量气体快速溶解法"、"母液稀释法"两种原理于一体的大容量新型变压器油中溶解气体检测装置检验系统。经测试证明:系统配制油样有较高的准确度和稳定性,具备操作简便、易于推广等优点。该系统的应用对电网范围内全面开展检测装置入网及运行中检验、提高充油电气设备监督和管理水平都具有重要意义。
Combined with the demand of calibrating on-line monitoring devices and portable testing devices when condition-based maintenance and live detection of power grid equipment are carried out, and on the basis of the in-depth study of standard sample preparation method for transformer oil, a set of new calibration system is developed for detection device of gases dissolved in oil of new-type transformer with large capacity is developed, combining two principles of 'quantitative gas quick dissolving method'& 'mother liquor dilution method'. It has been tested that the oil samples prepared in this system have high accuracy and stability. With the advantages of simple operation and easy to spread, the application of this system has important significance both in the acceptance test and operation inspection, the supervision and management level of oil-filled electrical equipment can also be improved.
