Description
Technical field
The utility model relates to a kind of birds defecation analogue means, is specifically related to a kind of for the birds defecation analogue means that affect experimental study of birds ight soil on the insulating property of transmission line of electricity.
Background technology
In recent years, being accompanied by the China Power developing steps constantly accelerates, China Power Grids is also developed rapidly, network system working voltage grade improves constantly, network size also constantly enlarges, the whole nation has formed Northeast China Power Grid, North China Power Telecommunication Network, Central China Power Grid, East China Power Grid, Northwest Grid and 6 large area electrical networks transprovincially of south electric network, and has basically formed complete long distance powedr transmission Net Frame of Electric Network.
China Power Grids construction in 2006 keeps higher scale, and the nationwide integrated power grid construction completes 2,105.75 hundred million yuans of investments, increases by nearly 38% on a year-on-year basis.China's transferring electricity from the west to the east three major path accumulative totals had formed the transport capacity of 3,400 ten thousand kilowatts along with a collection of the West-to-East Electricity Transmission Project is gone into operation in 2006.
2007,2451.40 hundred million yuan of nationwide integrated power grid construction investments, increased by 16.41% on year-on-year basis.4.15 ten thousand kilometers of newly-increased 220 kilovolts and above transmission line of electricity loop length.By the end of the year 2007,220 kilovolts, the whole nation and above transmission line of electricity loop length reach 32.71 ten thousand kilometers, increase by 14.20% on a year-on-year basis.
Eleventh Five-Year Plan period, be important 5 years that China's power grid construction carries forward the cause of the older generation and break new ground, and large quantities of great power transmission engineerings put into operation.Wherein, distant direct current, Xinjiang and a collection of high-grade, long distance, the built operations of jumbo power transmission engineerings such as northwest networking and extra-high voltage AC and DC are networked, exhaled in Hainan, opened the large electrical network epoch of China, promoted the enhancing of transregional exchange of electric power ability.The 2009 transregional exchange of electric power abilities in the whole nation in the end of the year surpass 2,500 ten thousand kilowatts, and annual transregional transaction electric weight reaches 1,213 hundred million kilowatt hours, increases by 51.1% than 2005.At present, China's electrical network scale has surpassed the U.S., leaps to the first in the world.
To the end of the year 2010, the whole nation 220 kilovolts and above transmission line of electricity total length reach 430,000 kilometers, and 19.6 hundred million kilovolt-amperes of power transformation capacity are respectively 1.7 times and 2.4 times of " 15 " end, and the electrical network scale leaps to the first in the world.The first three quarters in 2011, nationwide integrated power grid engineering complete 2,201 hundred million yuan of investments, power grid construction newly-increased 220 kilovolts and 12,817 ten thousand kilovolt-amperes of above power transformation capacity, line length 22507 kms.In Jan-Sept, 2011, national transregional power transmission amount completes 1,286 hundred million kilowatt hours, increases by 22.6% on a year-on-year basis; Electric weight 4,791 hundred million kilowatt hours are exported in the whole nation transprovincially, increase by 8.3% on a year-on-year basis.
China's intelligent grid pace of construction is accelerated, and the extra-high voltage grid engineering progress is smooth.The southeast-Nanyang, 1000 kilovolts of Shanxi-Jingmen UHVAC demonstration project, smoothly by national acceptance, indicates that extra-high voltage is no longer " test " and " demonstration " stage.In October, 2011, Wan Diandong send Huainan to Shanghai ultra-high voltage AC transmission demonstration project to obtain National Development and Reform Commission and checks and approves, and becomes the ultra-high voltage AC transmission project that national second is got permission to build after the southeast, Shanxi-Jingmen power transmission engineering.The strong intelligent grid of China entered the all-round construction stage in 2011, at demonstration project, electric vehicle charging, changed the aspects such as electric facility, new forms of energy admittance, Intelligent resident electricity utilization and carried forward vigorously.
Power grid construction has become the main direction of China's power construction at present, and the power grid construction prospect is tempting.During " 12 ", China's electric grid investment scale continuous expansion will be built up unified strong intelligent grid to the year two thousand twenty comprehensively, the preliminary target that realizes building world-class electrical network.
Along with the development construction of China's intelligent grid, also produced accordingly some problems, wherein the defecation of birds on transmission line of electricity also had influence on electrical network and moved normally.Well-known, on the cross-arm on the shaft tower top of ultra-high-tension power transmission line, usually have birds and stop falling; Generally, for the 500kV alternating current circuit, the hv transmission line that upper cross-arm and V-type insulator hang has the vertical range of 3.4m-3.8m, when normal operation, generally can not puncture, but when birds rest on cross-arm and discharge feces just downwards, due to Action of Gravity Field, the ight soil of similar liquid can form one section interrupted wire ight soil, effective air gap distance of cross-arm and transmission line of electricity is shortened, now, the electric discharge of the flashover of as easy as rolling off a log generation wire-cross-arm.This type fault also occur in repeatedly that 220kV, 330kV exchange and ± transmission line of electricity of the different electric pressures such as 400kV direct current on.
The inventor finds through long-term observation, research, designed a kind of for the birds defecation analogue means that affect experimental study of birds ight soil on the insulating property of transmission line of electricity, be specifically designed to simulation birds defecation and process thereof, the impact of research birds ight soil on the clearance insulating property of transmission line wire and shaft tower.
