Abstract

Abstract: Current power cable live detection technology has such problems as complicated operation, high detection difficulty, numerous equipment types and high testing personnel requirement. A new type of multi-parameter live detection device is thus designed for power cables. By configuring different types of sensor devices, it can detect a number of state quantities of power cables such as partial discharge, infrared-measured temperature, ground current and load current. Different sensing devices are modularized to facilitate the field detection. At the same time, the device has the functions of wireless communication transmission, human-computer interaction, data storage, etc. After interconnection with the cloud platform, it can realize the applications of platform detection task release, detection data return, data analysis and abnormal diagnosis, consequently reducing the technical requirements for detection personnel and meeting the requirements of intelligent inspection of power cables under the Internet of things mode. Through practical field application, the device can effectively improve the efficiency and enhance the application level of live detection of power cables, and save about 2/3 of the field workers, which has a wide range of practical and promotional values.

Key words: multi-parameter, power cable, partial discharge, live detection, Internet of things
