摘　　要：电场传感器用于绝缘子带电检测技术中,有两个制约绝缘子劣化检测结果精度的主要因素:一是空间电场测量的精度和稳定性,二是空间位置的分辨率和稳定性。通过对复合绝缘子电场分布进行计算分析,并通过试验进行了对比论证。结果表明:使用Pockels光学电场传感器提高电场强度精度以及使用电机进行测量位置准确定位,可显著提高对劣化绝缘子的分辨能力和带电检测的效果。The electric field sensor is used in insulator detection techniques, there are two main factors restricting insulator degradation test result accuracy, one is space electric field measurement accuracy and stability,the other is the space position resolution and stability. Based on the calculation and analysis on electric field distribution of composite insulators,and compared and demonstrated by experiment. The results show that improving the electrical field strength accuracy by using the Pockels optical electric field sensor and the measurement position is accurately located by using motor,the ability to distinguish the degradation insulator and the effect of energized detection can be significantly improve.
