“…Research has shown that condensation is one of the main causes of switchgear failures, and its harm is mainly manifested in reducing the mechanical and insulation performance of equipment. These exacerbate risks of surface tracking, insulation breakdown, and electrical arcing [2][3]. Therefore, studying the condensation problem of switchgear is of great significance for ensuring its safety and stability.…”

The drastic fluctuations in temperature and humidity in the switchgear environment can lead to condensation, posing the threat to the safe and dependable operation of power equipment. In response to the limitations of current anti-condensation measures, a new anti-condensation system for high-voltage switchgear is proposed. Firstly, this research provides an overview of the cause of condensation and the present situation of relevant prevention technologies. Secondly, a new anti-condensation system for high-voltage switchgear is presented. Drawing upon existing anti-condensation technology, this system effectively addresses prevalent issues such as high air humidity and facile condensation in high-voltage switchgear. Electric field simulation calculations, conducted using COMSOL simulation software, demonstrate that the system does not compromise the normal operation of the switchgear. Finally, practical applications show that the robust operational stability of the system. It consistently achieves precise heat dissipation and dehumidification in high-voltage switchgear, which has high application value.
