Description

technical field [0001] The invention relates to the field of ultra-high voltage external insulation, in particular to a small multifunctional environmental climate simulation device for high voltage test. Background technique [0002] The safety and stability of transmission line operation are important criteria to measure the quality of the design, and the external insulation design of the line is the basis for the safe operation of the line. its regularity. With the large-scale construction of UHV AC and DC transmission projects in my country, the line path will inevitably pass through areas with complex meteorological environments such as high altitude, heavy pollution, high conductivity fog, and repeated ice, which will lead to poor insulation performance of lines and power grids. Security is compromised to a certain extent. Therefore, in order to improve the reliability of the external insulation of UHV transmission projects in complex environments and ensure the safe ...

AI Technical Summary

Problems solved by technology

At present, the high-voltage air gap and surface discharge tests are mainly carried out in large-scale environmental climate laboratories where the environmental parameters are difficult to accurately control or small laboratories with incomplete functions. The test procedures are cumbersome, the environmental parameters are difficult to accurately control, and the test results are scattered. A large amount of manpower and material resources, work efficiency is not high, for experiments with high precision requirements, this technical solution obviously cannot meet the requirements of scientific research
