Simulation environment design for the investigation of damping and dewing mechanisms in the 12kV high-voltage switchgear

Abstract

The phenomenon of dampness and dewing inside the switchgear can improve the occurrence of serious equipment faults. Based on it, this paper, starting from the occurrence mechanism of dampness and dewing of the switchgear, summarizes the main techniques that can prevent and control them, and the merits and demerits of them are analysed. After that, based on the mechanism investigation of damping and dewing of 12kV switchgear, a simulation environment is designed in order to investigate the mechanism of damping and dewing the 12kV switchgear. Firstly, the entire simulation environment factors are given. Then, the prototype of this switchgear is designed, including base configuration and sensor installation configuration. In addition, the simulation environment of the distribution room, the switchgear with load operating conditions, several commonly used anti-dampness and anti-dewing methods of 12kV switchgear, and the rotary dehumidifier are designed. Lastly, prospects are given. This paper can provide some references for studying of damp-proofing and anti-dewing of 12kV switchgears.
