Background technology

In recent years, constantly accelerate with China Power developing steps, China Power Grids are also developed rapidly, 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.Go into operation with a collection of the West-to-East Electricity Transmission Project within 2006, China's three big passages of transferring electricity from the west to the east tire out 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 above transmission line of electricity loop length newly.By the end of the year 2007,220 kilovolts of the whole nation and 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, be 2002 4.2 Times, increase by 17.26% every year.

In Eleventh Five-Year Plan period, be that China Power Grids construction is carried forward the cause of the older generation and break new ground important 5 years, 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 extra-high voltage AC and DC etc. it is a collection of it is high-grade, over long distances, The power transmission engineering of large capacity is completed operation, opens the Chinese bulk power grid epoch, promotes the increasing of transregional exchange of electric power ability By force.For the transregional exchange of electric power ability in the end of the year 2009 whole nation more than 25,000,000 kilowatts, annual transregional transaction electricity reaches 121,300,000,000 kilowatts When, increased by 51.1% than 2005.China Power Grids scale exceedes the U.S., leaps to the first in the world, to the end of the year 2015, the whole nation 220,000 Volt and above transmission line of electricity total length reach 430,000 kilometers, and 19.6 hundred million kilovolt-amperes of power transformation capacity, is 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 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, it is necessary to it is a kind of it is economical, reliable, The mode of connection easy to maintain solves the problems, such as a large amount of branches in replacement first wife's rack ceases to be busy, and such as dual power supply case, dual power supply case is Automatic mains conversion and the device of power generation, for example dual power supply case will automatically switch to power generation circuit power supply, alternating current after mains failure Power generation circuit is disconnected automatically by twin-power switch after recovering normal, at the same time（There are several seconds time lags）Automatically engage city's electrical circuit Power supply, it is preferential that twin-power switch is typically arranged to alternating current.Dual power supply case makes circuit with its all insulation, hermetically sealed characteristic Failure rate is greatly lowered, and becomes the preferred unit of distribution network cable chemical industry journey, its simply, conveniently, flexibly couple combination, make It can replace ring main unit, improve the reliability of power supply, be widely used in commercial center, industrial park in some cases.But It is to be currently used for assembling dual power supply case, its small installation effectiveness in complicated and inner space is low, and when installation also can not be according to needs Carry out the accommodation of angle（Overall distribution box is needed to carry out the adjustment of angle when such as assembling, in order to efficiently be pacified Fill and use）, have been unable to meet the high standard requirement of existing cable assembling, and this is current urgently to be resolved hurrily.

Therefore, a kind of dual power supply distribution box is provided based on the above problem, the utility model.
