摘　　要：由于安装空间以及配件高度的限制,互感器的安装容易出现高低不平的状况,这易带来一定安全隐患。为了避免事故发生,设计一种互感器辅助安装装置,并提出了一种新的自动校验的方法。结果显示,基于随机矩阵的互感器安装装置自动校验设计具有良好的对电压偏差的评价性能。在平稳性上,状态统计量均大于阈值,平均值在约4.12,高于阈值2,具备良好的平稳分布特性。在固定偏差评价上,误差绝对值取值范围为0.2%以内,低于超差范围,d取值在1.82到1.96之间,评估方法能够辨识出固定偏差超差的情况。因此,这均表明研究所提供的互感器安装装置及其自动校验设计能够满足安装需求和偏差检验要求,具有实践价值。Due to the limitations of installation space and accessory height,the installation of transformers is prone to uneven conditions,which can bring certain safety hazards.In order to avoid accidents,this study designed a transformer auxiliary installation device and proposed a new automatic calibration method.The results show that the automatic calibration design of transformer installation device based on random matrix has good evaluation performance for voltage deviation.In terms of stationarity,the state statistics are all greater than the threshold,with an average value of about 4.12,which is higher than the threshold 2 and has good stationarity distribution characteristics.In the evaluation of fixed deviation,the absolute value range of error is within 0.2%,which is lower than the out of tolerance range,and the value of d is between 1.82 and 1.96.The evaluation method can identify situations where the fixed deviation is out of tolerance.Therefore,this indicates that the proposed transformer installation device and its automatic calibration design can meet the installation requirements and deviation inspection requirements,and have practical value.
