Abstract

Abstract: Temperature warning system for high voltage cable connectors plays an important role in protecting the safety of the transmission and distribution line operation. According to the actual layout of the high voltage cable connectors, the physical layer of the early-warning system of ZigBee network is responsible for the acquisition of the temperature of high voltage cable connectors. While the transport layer based on power fibers is in charge of the remote and reliable transmission of temperature data. Thus, a hierarchical-distributed temperature monitoring system for high voltage cable connectors was designed, which adopts ANN to measure the temperature of three-phase high voltage cables at some points, and achieves the temperature warning. The system has high reliability, scalability, and small temperature prediction error, which is suitable for on-line monitoring of the power sector.
