Abstract

The present invention provides a barometric pressure humidity controllable local discharge test device, pertaining to the high-voltage test equipment, specifically to a local discharge test device, wherein, the barometric pressure humidity controllable local discharge test device includes an insulation test box, the insulation test box is sealed, the top of the insulation test box is lead in a high pressure electrode, and a metallic substrate is provided at the bottom in the insulation test box, and the metallic substrate is grounded; the barometric pressure humidity controllable local discharge test device also includes a humidity regulator and a barometric pressure regulator communicated to the internal of the insulation test box. The inventive barometric pressure humidity controllable local discharge test device can regulate the humidity and barometric pressure in the test box to simulate different environments by setting the humidity regulator and the barometric pressure regulator in the test box, as the invention has simple structure and small size, it is suitable for the test of power equipment part with relatively small dimension and can effectively reduce costs.

Description

technical field [0001] The invention relates to a high-voltage test device, in particular to a partial discharge test device. Background technique [0002] With the development of my country's electric power industry, especially the hydropower industry, a large number of power plants and substations have been built in the upper reaches of many rivers and in high-altitude areas. Environmental factors such as special air pressure and humidity in high-altitude areas have an impact on the operation of power equipment, and partial discharge It is a key factor affecting the operation quality and life of these power equipment, so the research on the characteristics of partial discharge in high altitude areas has positive significance for the stable operation and life extension of these power equipment. [0003] Research on partial discharge in large-scale power equipment and external insulation can be carried out in artificial climate laboratories, but for relatively small power equ...
