| Abstract: | The extreme weather that caused the serious ice disaster in northern Guangdong in 2008 and the damaged equipment in power grid are comprehensively investigated. According to the icing sampling, ice coverage area, radial thickness of ice and originally designed ice thickness in northern Guangdong grid, the types, condition and causation of damaged line supports, ground wires, insulators and fittings are analyzed. Some proposals are offered, including paying attention to routing of new and rebuilt lines in Guangdong power grid, improving permission design limit and developing effective deicing means. |
