500kV alternating current to direct current voltage withstand test integrated device

Abstract

The embodiment of the invention discloses a 500kV alternating current to direct current voltage withstand test integrated device which comprises a container baseboard and a container top cover which are matched with each other, wherein baseboard steel frames are arranged on the container baseboard; four rectangular grooves are formed between the baseboard steel frames; a voltage-multiplying drum base and a voltage divider base respectively located on the two sides of the baseboard steel frames are arranged on the container baseboard; a supporting steel frame is arranged above the baseboard steel frames; a first rectangular steel frame is arranged above the supporting steel frame; a voltage divider grading ring is arranged on the first rectangular steel frame; a second rectangular steel frame is arranged above the voltage divider grading ring; and a voltage-multiplying drum grading ring is arranged on the second rectangular steel frame. According to the 500kV alternating current to direct current voltage withstand test integrated device provided by the embodiment of the invention, various test facility components are reasonably mounted and arranged in a container, a highly integrated device is formed, the convenience is brought to the loading, carrying and on-site mounting of the alternating current to direct current voltage withstand test device, and the efficiency of the onsite direct current voltage withstand test is promoted.

Description

technical field [0001] The invention relates to the technical field of equipment layout supporting mechanisms, in particular to an integrated device for a 500kV converter DC voltage withstand test. Background technique [0002] In recent years, DC transmission technology has developed rapidly, and the voltage level of DC transmission has also been continuously improved. At the same time, test devices or equipment for testing high-voltage transmission equipment have also appeared. [0003] For example, a converter transformer (abbreviated as a converter transformer) is an important piece of equipment in a high-voltage direct current transmission project. In order to ensure that the converter transformer maintains good insulation performance under high-voltage conditions, it is necessary to conduct a DC withstand voltage test on the converter transformer. However, in the prior art, the test device used for DC voltage withstand in the converter field is large in size, heavy in ...
