Review of Icing Issues and Prevention and Control Technologies for Power Transmission and Transformation Insulators
Ice covering on insulators is a major natural disaster that poses a threat to the safe operation of power grids
especially posing a severe challenge to the high-altitude and heavily ice-covered areas that strategic projects such as the West-to-East Power Transmission pass through. For this reason
this article systematically reviews the core research progress in the field of insulator icing. Firstly
it elaborates on the physical mechanism of icing and the coupling influence laws of its interaction with water droplet movement
environmental parameters
and electric fields. Then
the flashover characteristics of icing insulators are analyzed to reveal their nonlinear voltage characteristics and the development process of arcs. Finally
it summarizes and evaluates the applicability and limitations of three types of anti-icing measures
that is
structural optimization
active de-icing
and passive protection. The article points out that current research still lacks in the aspects of microscopic icing physics
multi-physical field coupling models
and insulators adaptability in extreme environments. In the future
efforts should be focused on the construction of intelligent anti-icing technology and the construction of a full-chain risk early warning system to support the reliable operation of future power grids.
