摘　　要：研制开发了一套充油电力设备油中电场测试系统．该系统的传感探头采用了ＰＯＣＫＥＬＳ电光晶体，探头输出信号经光纤输入微机进行数据采集与处理，应用该系统分别对平板电极之间、模型小套管尾部及２２０ｋＶ电容式变压器套管尾部油中部分的高压电场进行了测试，经与计算结果对比，证明了测试结果的正确性．In this paper, a fiber optic sensor utilizing the Pockels effect of Bi 12 SiO 20 is devised, and an electric field measuring system is developed for the measurement of 50Hz electric field in transformer oil. By using this measuring system, the electric field in oil of a plane plate, model bushing and at the lower part of 220 kV transformer bushing is measured. Comparing the measured data with calculation results, it is proved that this measuring system can be used for electric field measurements in oil filled power equipment.
