Technical field
The present invention relates to power circuit service equipment field, especially relate to the de-icing method and the device of transmission line.
Background technology
For electric power system, icing is a kind of natural calamity, the transmission line accident that China writes down the earliest comes across 1954, over nearest 30 years, large tracts of land freeze injury accident happens occasionally throughout the country, after 1974-1976 whole nation electric power system large tracts of land ice damage accident, large tracts of land ice damage accident took place again in the whole nation in 1984, particularly the 35-220KV of Fujian Province circuit in 1996 falls rod disconnection 200 places because of icing.
All kinds of transmission line ice trouble accident China took place thousands of times, over nearest 10 years, and the safe operation that serious icing accident has jeopardized the 500KV system.
Especially at the beginning of 08, most of provinces and regions, China south have met with rare snow disaster, this time the disaster process has caused 17 provinces (district, city, formation) such as Zhejiang, Jiangsu, Anhui, Jiangxi, Henan, Hubei, Hunan, Guangxi, Chongqing, Sichuan, Guizhou, Yunnan, Shaanxi, Gansu, Qinghai, Xinjiang and the Production and Construction Corps of Xinjiang disaster-stricken in various degree, and disaster also directly causes 1.01 hundred million mu in crops disaster area; 14.9 ten thousand of collapsed houses damage 60.2 ten thousand in house, and nearly 100 people's injures and deaths, because of the calamity direct economic loss reaches 326.7 hundred million yuan.Especially because of snow disaster causes the electric power facility damage, make rural area, southern most city cold dark because of power failure is absorbed in, caused very big inconvenience for these local masses' productive life, railway is stopped transport, and produces to stop production a lot of local power cuts to limit consumption.A lot of losses are all because snow disaster particularly causes electrical production decline because of the electric power facility damage.Collapsing of many electric power towers is exactly because the weight of the ice that covers on the transmission line far surpasses design load causes the distortion of electric power tower, topples, and not only causes power breakdown, even caused the personnel's that rush to repair injures and deaths.
For the anti-icing of transmission line and deicing present Research be both at home and abroad:
One, anti-icing mode: ferromagnetic wires, electromagnetic wave, heat absorber: wherein existing certain applications but anti-icing DeGrain, price height, power consumption is big and make and be difficult to promote.
Two, deicing technology: the main both at home and abroad at present heating power method that adopts.As: the mode of resistive line, short circuit current, overcurrent makes its heating to reach the purpose of deicing, because of power consumption is big, not obvious can't the popularization of suburb fruit.
Three, mechanical deicing: the technology that adopts both at home and abroad has at present: the mode of ad hoc, craft, its inefficiency and very dangerous is difficult to use in actual engineering.
In addition, according to resonance principle, solid objects all can produce vibration when being subjected to external force, and when external force was consistent with its natural frequency, its vibration was the strongest.If shatter a certain solid objects, adopting resonance is labour-saving way.
