Abstract

The current condensation phenomenon inside the ring main unit will cause corrosion of components, short circuits, partial discharges and other problems, which will seriously affect the safety and durability of power supply. In response to the above problems, this paper designs and builds a condensation test platform, conducts an experimental analysis on the factors that cause condensation, and combines the conclusions drawn to propose a remote monitoring system for anti-condensation. Operation and maintenance personnel can use a small program to remotely monitor the internal environment of the ring network cabinet and deal with condensation in a timely manner. The application of this system provides great convenience for the operation and maintenance personnel, and also has a significant impact on the monitoring and maintenance of the anti-condensation of the ring network cabinet.
