Description

A kind of device of the dust storm of collection in real time
Technical field
The invention belongs to environmental improvement equipment technical field, more particularly to a kind of device of the dust storm of collection in real time.
Background technology
Cover the province (Shan Xi ﹑ Gan Su ﹑ Ning Xia ﹑ Qing Hai ﹑ Xinjiang of northwest five in China great Northwest area) and one of the Inner Mongol Point, the gross area is about 1/3rd of the whole nation, and total population is about ten a quarters in the whole nation.Strategic position is important, natural resources It is abundant, it is deep to hide great potential, especially energy resources, no matter the equal reserves of the new energy such as fossil energy or wind and solar energy Considerable, prospect is tempting, can be rated as national " richest ", " transferring electricity from the west to the east " is the great strategic decision in China, while has also established big west Backlands area turns into the output base of China's 21 century energy.With the rapid development of economy, China's atmospheric environment faces sternness and chosen War, the issue of 2013 Nian9Yue State Council《Prevention and control of air pollution action plan》, National Energy Board's one side reinforcement Jing-jin-ji region, long three Angle, the management of the conventional construction of fire and electricity in Pearl River Delta area, coal-fired power project of keeping under strict control examination & approval, promote existing coal power technology energy-saving and emission-reduction to upgrade Transformation;On the other hand, to ensure the supply of electric power of phase of keeping under strict control, with reference to the development & construction of coal-electricity base, according to " delaying after first urgency, first Yi Hounan, safety economy, science are pragmatic " principle propose the preferential passways for transmitting electricity for building 12 transferring electricity from the west to the easts, so far " Xi electricity Dong Send " Important Project raises speed suddenly.The Northwest's new energy was built like a raging fire simultaneously, to the province's the whole network total installed capacity of northwest five in 2016 Capacity is up to 400,000,000 kilowatts, wherein more than 70% can be used for sending outside.So far, 3 passages put into operation, remaining is defeated Electric channel is also promptly doing preliminary preparation, it is contemplated that next year will put into operation successively.It is defeated according to initial estimate, this 12 extra-high voltages Electric channel ability to transmit electricity can ensure that Beijing-Tianjin Hebei and Shandong, the Yangtze River Delta, the power demand in Pearl River Delta area, can be reduced every year after building up Area about 100,000,000 tons of consumption of coal of mark is stated, this is for improving Beijing-Tianjin Hebei and Shandong, the external electricity suppl in Yangtze River Delta Area and supportability, alleviation Environmental pressure has very great meaning.
But the region of a large amount of strong wind sand environments is dispersed with the Northwest, the high voltage power transmission corridor of " transferring electricity from the west to the east " will be frequent The desert and Gobi area of these high and cold droughts is passed through, strong wind sand environment will cause great influence to power transmission and transformation line.
By taking Xinjiang region as an example, major province of energy of the Xinjiang as China, the important task of " boundary electricity is sent outside " is not only responsible for, will also Carry the important task that the transnational energy interconnects.At present, 750kV transmission lines of electricity and ± 800kV, ± 1100kV transmission lines of electricity are being built By Xinjiang, the special weather area comprising -40 DEG C of western hundred inner Wind-sandy Areas and the lowest temperature, and in recent years, positioned at Xinjiang " three There occurs a lot of wire strand breakage events, more than 8 grades of the region for the power transmission and transforming equipment of the strong wind area such as Shi Lifeng areas " and " Bai Lifeng areas " Wind speed annual number of days was up to 160 days, wherein 12 grades and nearly 90 days of above strong wind weather, harsh climate environment has greatly tested line The safe operation on road.
Among overhead power transmission line line conductor exposes open field for a long time, the influence of harsh natural climate condition is highly prone to, Such as wind, rain, ice, snow, husky invasion and attack.Wire strand breakage affected by wind is maximum.Typhoon, wind-force is very big, wire because by Huge wind load or shaft tower collapse tensile load effect exceed cable tensile strength and be broken;Usually gentle breeze of most of period Be constantly present, the cyclone that gentle breeze is formed makes the wire moment be in vibrational state, after operation a period of time, hanging conductor clamp, Near the hanging wires such as strain clamp point and the strong point, often there is fretting fatigue wear phenomenon, severe development to later stage is stranded;Ice and snow Weather makes its cross sectional shape of wire icing be superimposed wind action again and wire is easily waved and cause stranded therewith changing;Also Because construction reason cause wire and wire clamp loose contact it is exothermic melting and stranded;Make conductive line surfaces wound accidentally because constructing as splitting Line source then fatigue accelerate extension and it is stranded;Conductor cross-section corrosion is caused gradually to deepen to make effectively to carry because being on active service in corrosive environment Area reduce and it is stranded;And the stranded behavior actually occurred is often the compound action of several stranded mechanism above, therefore very It is necessary to analyse in depth and studies overhead power line wire strand breakage reason under various circumstances, from design, construction, operation, dimension Constantly analyze, summarize in shield, take timely and effectively targetedly precautionary measures be reduced or eliminated wire strand breakage it is various not Sharp factor, so as to improve overhead power line reliability of operation and security.
It is close with local environment that wire strand breakage behavior can be seen that by above-named several frequently seen wire strand breakage mechanism Cut is closed.By taking strong wind sand environment as an example, its strands breaking mechanism is very different with described above and reality.
High wind is also referred to as strong wind, but is not typhoon after all, is less gentle breeze.Wire strand breakage its mechanics machine under typhoon System is very clear, and it is loaded super to the disposable ductile fracture mechanism destroyed, wire institute to be just analogous to laboratory tension test Cross its material yield strength and be broken.But it is also different from the high cycle fatigue fracture mechanism caused by aeolian vibration, aeolian vibration Cycle-index is very big, long between lasting, and can effectively be prevented and treated by installing damper additional.The strong wind sandy land drought in Xinjiang, though It is so high and cold, but icing difficulty, into normality, high wind rank is very high in addition, and the conductor galloping that can destroy the stabilization characterized by intermediate wind shows As, thus do not belong to yet wave it is stranded;Put aside that exothermic melting stranded and surface caused by artificial loose contact caused by construction weighs wounded That brings is stranded, it is believed that stranded under the conditions of high wind sand may follow a kind of new stranded mechanism.It is micro- under windy conditions Vibrating and waving does not account for leading, and wire actually more they tends to swing, and amplitude of fluctuation is larger, for not installing drawing for safeguard procedures additional It is even more so for streamline, therefore the stranded of it is more closely similar to a kind of strain fatigue mechanism, namely what is often called low-cycle fatigue.
Plus the impact of the high momentum grains of sand of high concentration, the surface of wire has intensive scuffing, and the scuffing causes wire table Surface roughness increase, surface fatigue formation of crack increase, and add the degree of fatigue, and on the other hand, it is existing that dust storm exacerbates abrasion As, and the cut that can eliminate part surface in turn is worn, face crack source quantity is reduced, is also possible to the grains of sand certainly Have and moved in crackle and further deepen established crackle, therefore fatigue plus the compound action of abrasion constitute high wind sand condition Under stranded behavior.In addition the grains of sand with saline alkali are also not excluded for the corrosiveness of fracture location and due to the grains of sand Filling effect have impact on the good contact of wire and wire clamp and cause to generate heat temperature rise and stranded.
Based on such analysis, the test platform of proposed vertical wire strand breakage simulates its possible stranded behavior, is come with this Analyze its strands breaking mechanism.According to the damage, it is necessary in view of grit in the presence of high wind is swept along to conductive line surfaces is analyzed above Behavior, therefore, to collect the data for the dust storm that wire strand breakage region occurs, main to include wind speed live on the spot, grit form, Situations such as sand amount.As needed, it is necessary to design a kind of device of collection site dust storm in real time.
In summary, the problem of prior art is present be:
Existing transmission line of electricity is all over existing because high wind sand causes transmission line breakage;And prior art does not establish wire Stranded test platform analyzes its possible stranded behavior, and its strands breaking mechanism is analyzed with this;Swept along for grit in high wind In the presence of derogatory behaviour to conductive line surfaces, prior art also a kind of can collect the live husky feelings such as measure on the spot without providing The reason for device of condition data, the damage of analyzing influence conductive line surfaces and stranded region;
Prior art defect, first, can not efficiently collect grit because of grit high speed impact;Second, remotely it cannot supervise in real time Control the weight change situation of grit in certain time;Third, can not exclude in real-time monitoring because ponding accumulated snow and caused by gravity The measurement error of sensor.
