A Review of Icing and Anti-Icing Technology for Transmission Lines

This paper reviews the application of various advanced anti-icing and de-icing technologies in transmission lines. Introduces influence snowing icing disasters on lines, including a mechanical overload steel towers, uneven or at different times, Ice-covered conductors galloping flashover insulators, as well lines around world recent years. The formation categories effect meteorological factors, topography, altitude, line direction, suspension height, shape, electric field ice-covered are all discussed this study. anti/de-icing their advantages disadvantages power summarized. traditional force, AC/DC short-circuit ice melting, corona is introduced. Torque pendulum diameter-expanded conductor (DEC) have remarkable effects, early investment resources less, cost low, later maintenance not needed. In view some deficiencies AC DC current transfer intelligent melting device (CTIIMD) can solve problem well. gadget has good high reliability for addition to being compact inexpensive. hydrophobic materials heating coatings insulators certain effect, but service life needs further research. Optimizing shed’s construction arranging several string kinds advisable prevent effect. building an insulator, only shed layout uses non-consumption energy.
