Research and application of 10kV cable condition assessment online monitoring device based on improved fuzzy theory

Abstract

Distribution cable is an important part of distribution network, and its running state has an important influence on the normal operation of distribution network. At present, the maintenance of distribution cables is mainly based on offline regular maintenance mechanism, which cannot monitor the operation status of cables in real time, and the regular maintenance is not targeted and the monitoring method is relatively single. Therefore, the comprehensive evaluation method of improved fuzzy theory is used to evaluate the operation state of distribution cable, and a set of cable on-line monitoring device is designed. The designed device is installed and debugged on site, which verifies that the device can effectively monitor the state of cable.
