Problems solved by technology
Among them, the structure of the device tower is very complicated, the volume is huge, and the number of parts is large
The on-site assembly and disassembly process is long, time-consuming and labor-intensive, and requires a lot of installation equipment
It needs to be installed piece by piece with the help of a large crane, which is extremely inefficient. At the same time, due to too many installation and connection parts, the reliability of the equipment is affected
And many of the components are very bulky and expensive to transport

Embodiment Construction
[0024] Such as Figure 1 to Figure 5 As shown, the tower structure of a UHV DC non-PD test device according to the present invention includes a pressure equalizing ring assembly 1, a voltage doubler assembly and a supporting chassis 3 arranged in sequence from top to bottom. The tower structure of the whole device is over 11m in height after installation.
[0025] Such as figure 2 , image 3 As shown, the pressure equalizing ring assembly 1 includes an upper pressure equalizing ring 11 , a lower pressure equalizing ring 12 and a plurality of support columns 13 . Both the upper pressure equalizing ring 11 and the lower pressure equalizing ring 12 are split structures. The upper pressure equalizing ring 11 is composed of two semi-annular first semi-annular bodies (not shown in the figure) butted together, and the two first semi-annular bodies are detachably connected. Similarly, the lower pressure equalizing ring 12 is composed of two semi-annular second semi-annular bodies...

The invention relates to a structure of an ultra-high-voltage direct-current partial discharge free testing device tower. The structure of the ultra-high-voltage direct-current partial discharge free testing device tower comprises a voltage equalizing ring component, a voltage multiplying component and a support bottom rack, wherein the voltage multiplying component comprises multiple sections of voltage multiplying units; the voltage multiplying units comprise voltage measuring and separating columns, a plurality of voltage multiplying rectification capacitor columns and a plurality of silicon stacks; the voltage measuring and separating columns and the plurality of voltage multiplying rectification capacitor columns are arranged in a linear array manner; a plurality of silicon stacks are mounted between adjacent voltage measuring and separating columns in a same row or same line; the silicon stacks are fixedly connected with adjacent voltage measuring and separating columns. The structure of the ultra-high-voltage direct-current partial discharge free testing device tower is separated into components and units which are limited in number and are independent from one another, so that on-site mounting difficulties can be alleviated, use of mounting equipment can be reduced, the working efficiency is greatly improved, convenience in packaging and transportation can be brought, and the transportation cost can be lowered.
Description
technical field [0001] The invention belongs to the field of direct-current high-voltage test equipment, and in particular relates to a tower structure of an ultra-high-voltage direct-current non-partial discharge test device. Background technique [0002] At present, DC voltage generator is a necessary equipment for DC high voltage test research. Its function is to carry out experimental research work on DC withstand voltage, gap discharge, DC corona, DC partial discharge, DC polarity conversion, and impact superimposed DC.
