Problems solved by technology

[0003] In UHV lines, UHV converter stations or substations, there are usually weak current measurement systems on the high voltage side, and these weak current measurement systems often have unstable performance and poor measurement results due to corona discharge caused by being in a high-voltage electric field environment. Phenomena such as unreliability occur

Abstract

The invention relates to an anti-corona device for an electronic measurement system in an ultra-high voltage electric field environment. The device includes a connection plate arranged in sequence from top to bottom, a top pressure equalizing ring vertically connected to the connection plate, a pressure equalization Ring support legs, flat-bottomed balls and bottom pressure equalizing ring; the connecting plate is connected to the top pressure equalizing ring through the pressure equalizing ring support legs; the top pressure equalizing ring is horizontally arranged parallel to the bottom pressure equalizing ring. The surface field strength of the device is small, which can well prevent the influence of corona on the internal measurement system, and effectively protect the electronic measurement device under the high-voltage electric field environment.

Description

Technical field: [0001] The invention relates to an anti-corona device, in particular to an anti-corona device for an electronic measurement system in an ultra-high voltage electric field environment. Background technique: [0002] In order to implement the national energy policy and ensure the comprehensive, coordinated, sustainable and healthy development of the power industry, the State Grid Corporation of my country has proposed a major strategic measure to accelerate the development of AC and DC UHV power grids according to China's national conditions. UHV transmission is developed on the basis of ultra-high voltage transmission, which can realize long-distance and large-capacity transmission of electric energy, and is suitable for the interconnection of large-scale power grids. Due to the high voltage level, corona phenomenon will inevitably occur on UHVDC transmission lines. The corona effect of UHVDC transmission lines includes corona loss, electric field effect, rad...
