Cable Status Evaluation Method Based on Feature Fusion
Aiming at the problem of lack of effective condition monitoring system and evaluation method in the op-eration and maintenance of distribution cable lines in our country,in the paper based on four types of structured data of local discharge,joint temperature,current carrying capacity and DC component of distribution cables,extracts the time-series data model and fuses the features of the previous layer of softmax in the image evaluation model,and proposes a feature fusion based condition evaluation method for medium voltage distribution cables;Finally,the ef-fectiveness of the proposed multimodal integration method is verified by the actual data validation of a certain place.This method can be used to improve the support ability of the distribution cable differential accurate operation and maintenance and decision-making guidance,comprehensively improve the operation safety level of the distribu-tion cable network and the support ability of lean management technology,and help the distribution network to a-chieve breakthroughs in intelligent upgrading and business Digital transformation.
