Description

technical field [0001] The invention relates to an electric field distribution monitoring device for ultra-ultra-high voltage line insulators, and belongs to the technical field of electric field intensity monitoring equipment. Background technique [0002] Insulators are one of the important components of overhead transmission lines, and their performance will directly affect the operation safety of the entire line. As the voltage level of transmission lines increases, the mechanical and electrical loads on insulators are increasingly aggravated, which makes the power grid normal The operation has higher and higher requirements on the quality of insulators. Insulators are widely used in the entire power transmission and distribution system, especially in the EHV, UHV AC and DC transmission systems that have been vigorously developed in recent years. The problem of safe operation of insulators is even more serious. It directly determines the investment and security level of ...
