The safety for drawing operation when cable construction is protected, reduces the friction to cable, while can timely carry out quick receiving/releasing
Operation, and improve the safety that uses and cable up/down install convenient, can be according to needing to carry out height adjustment.
Background technique
In recent years, constantly accelerate along with China Power developing steps, China Power Grids are also rapidly developed, network system
Working voltage grade is continuously improved, and network size also constantly expands, and the whole nation has formd Northeast China Power Grid, North China Power Telecommunication Network, Central China
Power grid, East China Power Grid, the large area power grid of Northwest Grid and south electric network 6 transprovincially, and basically formed complete length away from
From power transmission electric network rack.China Power Grids construction in 2006 keeps higher scale, and investment 2,155.75 hundred million is completed in nationwide integrated power grid construction
Yuan, increase by nearly 38% on a year-on-year basis.It goes into operation with a collection of the West-to-East Electricity Transmission Project within 2006, three big channels of China's transferring electricity from the west to the east are tired
Meter has formed 3,4000000 kilowatts of conveying capacity.2007,2451.40 hundred million yuan of nationwide integrated power grid construction investment, increase on year-on-year basis
16.41%.Increase 220 kilovolts and 4.15 ten thousand kilometers of the above transmission line of electricity loop length newly.By the end of the year 2007,220 kilovolts of the whole nation and
The above transmission line of electricity loop length reaches 32.71 ten thousand kilometers, increases by 14.20% on a year-on-year basis.To the end of the year 2008, electric power installed capacity reaches
To 7.9253 hundred million kilowatts, generated energy reaches 3,433,400,000,000 kilowatt hours.Power transformation capacity reaches 2,200,000,000 kilovolt-amperes, is 4.2 in 2002
Times, increase by 17.26% every year.
Eleventh Five-Year Plan period is important 5 years that China Power Grids construction is carried forward the cause of the older generation and break new ground, and large quantities of great power transmission engineerings, which go into operation, to be built
If, wherein Hainan networking, exhale distant direct current, Xinjiang and northwest networking and a batch such as extra-high voltage AC and DC it is high-grade, over long distances,
The power transmission engineering of large capacity, which is completed, goes into operation, and opens the Chinese bulk power grid epoch, promotes the increasing of transregional exchange of electric power ability
By force.The transregional exchange of electric power ability in the end of the year 2009 whole nation is more than 25,000,000 kilowatts, and annual transregional transaction electricity reaches 121,300,000,000 kilowatts
When, increased by 51.1% than 2005.China Power Grids scale has been more than the U.S., is leapt to the first in the world, to the end of the year 2015, the whole nation 220,000
Volt and the above transmission line of electricity total length reach 430,000 kilometers, and 19.6 hundred million kilovolt-amperes of power transformation capacity, be the 1.7 of " 15 " end respectively
Times and 2.4 times, power grid scale leaps to the first in the world.The first three quarters in 2011, nationwide integrated power grid engineering complete 220,100,000,000 yuan of investment, electricity
Net, which is built, increases 220 kilovolts and 128,170,000 kilovolt-amperes of the above power transformation capacity, 22507 km of line length newly.In Jan-Sept, 2011, entirely
The transregional power transmission amount of state completes 128,600,000,000 kilowatt hours, increases by 22.6% on a year-on-year basis;The whole nation transprovincially exports 479,100,000,000 kilowatt hour of electricity, on year-on-year basis
Increase by 8.3%.
In conclusion power network line development in China's is very fast, in transmission line construction engineering, need to provide a kind of structure
The receiving/releasing operation of relief cable line, inconvenience unwrapping wire and unwrapping wire scene is chaotic and what is knotted shows when solving existing construction operation
As.But it is currently used for the pay off rack of cable construction operation, its structure is complicated and cable up/down material installation effectiveness is low, installation
When also (can not such as need the cable of unwrapping wire more, and the space of bottom plate is smaller to carry out according to needing to carry out height adjustment
When feeding etc.), have been unable to meet the high standard requirement of existing cable construction, and this is current urgently to be resolved.
Therefore, based on the above issues, the present invention provides a kind of vertical type adjustable cable pay-off rack.
