Description

technical field [0001] The invention relates to the field of electric power transmission, in particular to a method and a device for determining the shed parameters of post insulators. Background technique [0002] Post insulators (such as composite post insulators) are essential elements in power transmission engineering. With the continuous improvement of voltage levels, composite insulating materials are widely used in my country because of their excellent pollution flashover resistance. However, composite post insulators have the characteristics of large volume, various umbrella structures, and high cost. [0003] In the prior art, a large number of composite post insulator samples are purely used for experimental research, in order to obtain samples with better pollution flashover resistance from these samples, so as to carry out production according to the parameters of the samples. However, this is not only expensive but also time-consuming. Contents of the invent...
