Description
Technical field
The present invention is that a kind of long string composite insulator sprays dirty device automatically, belongs to long string composite insulator and automatically sprays the innovative technology of dirty device.
Background technology
The development UHV transmission is the Important Action on China's electric power development history, for the Efficient Development utilization that realizes wider most optimum distribution of resources and promotion China energy, is significant.Built many 1000kV ultra-high voltage AC transmission engineerings of China and ± 800kV extra-high voltage direct-current transmission engineering.At present, China is building silk screen-southern Jiangsu and two, Nuo Zhadu-Guangdong extra-high voltage ± 800kV DC transmission engineering.During " 12 ", also, with the multinomial extra-high voltage AC and DC of planning construction engineering, will greatly promote " transferring electricity from the west to the east " ability.
Choose reasonable circuit external insulation configuration is to build one of key issue that UHV Transmission Engineering faces.Compare with other countries, China's geographical environment is complicated, atmosphere pollution is serious, has cancelled clear area in the design planning of power transmission engineering.Along with improving constantly of transmission voltage grade, the external insulation problem is more and more outstanding, is the important factor for controlling of UHV Transmission Engineering design, and the cost of power transmission engineering is had great impact.Therefore, carrying out the insulator artificial pollution flashover test, to be used for the discharge problem of staining of research external insulation significant.The research of the artificial Flashover Characteristics of high voltage external insulation belongs to tentative science, and influence factor is many and complicated.Many phenomenons can not be depended merely on theoretical calculating or with the model test of dwindling, analyze, and will be near the prototype test of actual size.Utilize the result of prototype test to instruct the design of Practical Project more reasonable, reliable.
The insulator of applying in circuit at present mainly contains porcelain insulator, glass insulator and composite insulator.Composite insulator partly is comprised of full skirt, sheath and plug etc., and owing to having adopted organic material, total amount is light, and resistant sudden strain of a muscle performance is good, is applied widely in electrical network.Especially extra high voltage line, lower than porcelain and glass insulator, the ratio of composite insulator in extra high voltage line is far above other electric pressures due to composite insulator string length.Therefore, for the artificial Flashover Characteristics research of the long string of extra-high voltage composite insulator, significant.
Staining the preparation of test product, is the important step of the artificial pollution flashover test research of composite insulator.The test product preparation method that stains commonly used has quantitative brushing method, soaks dirty method and spray dirty method etc. at present.Wherein quantitatively brushing method is the least to the dependence of equipment, and strong adaptability stain the test product preparation method for what Domestic Scientific Research unit generally adopted, but this method is taken manpower most, efficiency is low, the test product preparatory period is long.Soak dirty method and need to prepare to soak dirty pond, soiling solution is long setup time, but after configuration successful, once can prepare more test product.Spray dirty method and save manpower, efficiency is high, but high to the equipment dependence, adjusts device parameter after needing in process to detect spraying effect, therefore operating personnel is required high.When test in the past, be short string test product, the problem that test product is prepared efficiency is outstanding, therefore adopts quantitative brushing method and soaks dirty method more, sprays the less employing of dirty method, therefore the domestic also less research of carrying out the dirty method equipment of spray.But for needing at present the long string composite insulator test of carrying out badly, quantitatively brushing method is very obvious with the shortcoming of soaking dirty method.For example, the artificial pollution flashover test of the composite insulator of a 12m length, 1 data point needs 10 independent experiments, needs to prepare 10 and stain test product.If adopt quantitative brushing method, need 6 skilled workers to brush 30 hours, efficiency is extremely low, has seriously restricted the progress of artificial pollution flashover test.Soak dirty method and be easy to the dirt of soaking of short insulator string, but for long-string insulator, soak dirt, need the larger dirty pond of soaking, simultaneously, once soak the dirty suspension that needs configuration once to infiltrate use, the suspension liquid measure of soaking the each needs in dirty pond that capacity is larger is larger, waste greatlyr, and larger soak dirty pond, the uniformity of suspension is more difficult to be met, therefore soak dirty method preparing artificial pollution flashover aspect long string composite insulator test product, have difficulties.And it is little to spray dirty method volume, and the mixed liquor that configures all is sprayed onto the long-string insulator surface, and wastage is few, and the dirty work of the spray of a 12m insulator, only need 5 minutes, greatly improved efficiency.But spray dirty method because domestic research is less, also have some problems, such as easy blocking pipe of mixed liquor etc.
Summary of the invention
The object of the invention is to consider the problems referred to above and provide a kind of and increase work efficiency, saving the long string of human cost d composite insulator and automatically spray dirty device.The present invention is reasonable in design, and is convenient and practical.
Technical scheme of the present invention is: long string composite insulator of the present invention sprays dirty device automatically, include fluid reservoir, automatic blending system, the dirty device of spray, removable bracing frame, wherein automatic blending system is installed on fluid reservoir, fluid reservoir and spray dirty device and be arranged on described removable bracing frame, and the set liquid outlet of the inlet that sprays dirty device and fluid reservoir communicates.
The present invention carries the structure of stirring system due to employing, can guarantee that spray liquid is even, and the liquid storage amount of the fluid reservoir of providing for oneself is through calculating design, and nargin is reasonable, a dosing, and the preparation of the whole test products that can guarantee test require, do not cause again waste.Designed filter at fluid reservoir with the place that the dirty pipeline of spray is connected, can prevent that unmixed uniform suspension from entering pipeline, blocking pipeline.The present invention can increase work efficiency greatly, saves human cost.It is ingenious, simple to operate, practical that the present invention designs.The present invention is that a kind of design is ingenious, function admirable, and convenient and practical long string composite insulator sprays dirty device automatically.
