摘要

The outdoor insulation of the overhead transmission lines in Hunan Power Grid is checked in the paper,the results display that 66.05％of 220kV transmission lines cannot meet the demand of preventing ice-melting flashover,and for 500kV transmission lines,the percentage is 36.17％.And in the superposition region of heavy icing area and e class pollution area,there are 1.03％of towers which cannot meet the demand of preventing ice-melting flashover in 220kV transmission lines,and for 500kV transmission lines,the percentage is 0.45％.Self-defect and insufficiencies of anti-icing improvement are the primary causes of the poor preventing ice-melting flashover capacity in the overhead transmission lines.The strategy of preventing ice-melting flashover are proposed,such as improve the forecast accuracy,reinforce the manager of ice condition observation,classify and focus on the poor prevent ice-melting flashover capacity facility.And the operation and improvement advice for preventing ice-melting flashover are also proposed in the paper.
