Description

technical field [0001] The invention belongs to the technical field of high-voltage gas discharge measurement, in particular to a method and device for measuring the spatial distribution of ion flow in split wires. Background technique [0002] High-voltage direct current transmission technology has the advantages of large capacity, strong stability, and relatively low cost, and is especially suitable for the interconnection between regional power grids and long-distance large-capacity power transmission. At present, in order to solve the practical problem that the resource location is far away from the load center, my country has started the construction of large-scale UHV DC transmission lines. For the sake of line economy, DC transmission lines are usually designed in an operating state that allows a certain degree of corona, resulting in corona problems. The corona of the DC transmission line will produce many effects. For example, the charged ions generated by the coro...
