Problems solved by technology

The traditional manual deicing method has low efficiency, long power outage time and low safety
The hot air deicing method does not affect the power supply, and the deicing efficiency is high, but it requires high insulation performance
[0003] The water film produced during the live deicing process of substation equipment will reduce the insulation performance of the equipment to a certain extent
At present, the use of hot air live deicing mainly relies on experience, and there is a lack of guidance on the deicing path of ice-coated substation equipment, which leads to blind selection of deicing paths, and there is a risk of tripping during the melting process

Description

technical field [0001] The invention relates to the technical field of power grid deicing and disaster mitigation, and in particular to a method, system and storage medium for selecting a hot air deicing path for substation equipment. Background technique [0002] Icing seriously affects the electrical and mechanical performance of substation equipment, threatening the safe and stable operation of large power grids. During the ice disaster in 2008, 36 220kV and above substations in our province’s power grid were out of service due to freezing of switchgear, more than 100 sets of isolating switches, circuit breakers and other equipment were damaged, and more than 700 trips of lines and substation equipment ice flashed. A loss of more than 7 billion yuan. The traditional manual deicing method has low efficiency, long power outage time and low safety. The live hot air deicing method does not affect the power supply and has high deicing efficiency, but requires high insulation...
