Development and Application of Integrated Smart Terminals Based on Holographic Sensing of Switchgear in Substations

This paper develops an integrated smart terminal device based on holographic sensing of switchgear. The device is mainly used for integrated and unified management of online monitoring devices of 10 kV switchgear. It can be divided into four modules, which separately correspond to the contact temperature monitoring, partial discharge monitoring, mechanical characteristics, and electronic chassis control of the switchgear.
