【摘要】：絕緣子表面在自然條件下會積累各種不同類型的污穢成分,而其中不溶物會對絕緣子污閃電壓產(chǎn)生一定影響。該文選用7片標(biāo)準(zhǔn)懸式瓷和玻璃絕緣子串作為研究對象,試驗(yàn)研究了其在不同不溶物下的交流閃絡(luò)特性,結(jié)合不溶物不同類型及顆粒直徑下的絕緣子污穢試驗(yàn)測量結(jié)果,分析了不溶物對絕緣子閃絡(luò)電壓的影響。結(jié)果表明:不同不溶物類型對污閃電壓的影響有差異,但不同種類的不溶物基本不會對可溶物的影響指數(shù)產(chǎn)生影響;不溶物顆粒直徑對污閃電壓存在一定影響,在絕緣子類型,鹽灰密與污穢成分相同條件下,污閃電壓隨不溶物粒徑的增大而增大。因此,在絕緣子污閃研究中,不能僅用高嶺土或者硅藻土模擬灰密得到的試驗(yàn)結(jié)果來分析評判所有不溶物對絕緣子閃絡(luò)的影響,需要綜合考慮不溶物的各種成分類型以及其粒徑大小等多種因素的影響。
[Abstract]:The insulator surface will accumulate various kinds of pollution components under natural conditions, and the insoluble matter will have a certain effect on the insulator flashover voltage. In this paper, seven pieces of standard porcelain and glass insulator strings are selected as the research objects. The AC flashover characteristics of the insulators under different insoluble materials are studied experimentally, and the results of insulator contamination test under different types of insoluble materials and particle diameters are measured. The influence of insoluble matter on the flashover voltage of insulator is analyzed. The results show that the influence of different insoluble material types on the flashover voltage is different, but the influence index of the soluble matter is not affected by the different kinds of insoluble matter, and the diameter of the insoluble particles has a certain influence on the flashover voltage, in the insulator type, The flashover voltage increases with the increase of the particle size of the insoluble matter. Therefore, in the study of insulator flashover, the influence of all insoluble matter on the flashover of insulator can not be analyzed and evaluated only by the test results of kaolin or diatomite simulating ash density. The influence of various composition types and particle size of insoluble matter should be considered.
