【摘要】：户外工况下的绝缘子由于环境因素的作用导致性能劣化,当劣化到一定程度时,绝缘性能就会降低,需要对绝缘子的运行状况进行检测。设计一种基于"日盲"紫外脉冲检测的变电站绝缘子劣化程度远距离检测装置,并提出运用非线性回归方法寻找绝缘子劣化程度与距离、紫外脉冲数、环境湿度间的关系式,将绝缘子劣化程度以百分数的形式表示并划分等级,使得检测结果清晰直观。测试结果证明,该系统能够判断绝缘子的劣化程度,推导的劣化程度数学关系式能作为绝缘子劣化程度判断的准确依据。此研究结果可为在线评估变电站绝缘子劣化程度提供方法和思路。
[Abstract]:The performance of insulators under outdoor working conditions is degraded due to the environmental factors. When the insulators deteriorate to a certain extent, the insulation performance will be reduced, so the operation condition of the insulators should be tested. A remote detecting device of insulator deterioration degree in substation based on "sun blind" ultraviolet pulse detection is designed, and a nonlinear regression method is proposed to find the relationship between insulator deterioration degree and distance, ultraviolet pulse number and environmental humidity. The insulator deterioration degree is expressed and graded in percentage form, which makes the detection result clear and intuitive. The test results show that the system can judge the deterioration degree of insulator and the mathematical expression of deterioration degree can be used as the accurate basis for judging the deterioration degree of insulator. The results can be used to evaluate the deterioration of insulators in substation.
