Description

1. Technical field [0001] The invention relates to a high-voltage power transmission cable deicing device, which belongs to a high-voltage power transmission auxiliary device. 2. Background technology [0002] Freezing rain and snow accumulation in winter often lead to ice accumulation on transmission cables. If the ice accumulation is not removed for a long time, it will seriously threaten the safe operation of the power grid. The accidents caused by cable ice accumulation have caused huge economic losses to the country. Damage to hardware, brittle cables, and even tilting or collapse of towers caused by severe ice accumulation often lead to large-scale power outages and affect people's normal production and life. [0003] At present, there are two main ways of deicing: one is artificial deicing, that is, sending electric workers to beat the ice accumulation with wooden sticks, which is inefficient, has great limitations, and is very dangerous; the other is short-circuit ic...

[0002] Freezing rain and snow accumulation in winter often lead to ice accumulation on transmission cables. If the ice accumulation is not removed for a long time, it will seriously threaten the safe operation of the power grid. The accidents caused by cable ice accumulation have caused huge economic losses to the country.

Damage to hardware, brittle cables, and even tilting or collapse of towers caused by severe ice accumulation often lead to large-scale power outages and affect people's normal production and life

[0003] At present, there are two main ways of deicing: one is artificial deicing, that is, sending electric workers to beat the ice accumulation with wooden sticks, which is inefficient, has great limitations, and is very dangerous; the other is short-circuit ice melting, that is, Let the circuit be short-circuited instantly to generate heat and deicing, but this method will inevitably lead to power interruption, and the energy consumption is huge, but the effect is not ideal

Judging from the prior art, there is no efficient and practical deicing machine for high-voltage transmission lines
