Problems solved by technology
Every time the particles are added, the device must be disassembled, which greatly reduces the reliability of each experiment, and it is difficult to ensure that the initial conditions of the particle environment do not change before each experiment
At the same time, dismantling the tank multiple times will reduce the service life of the tank, increase the preparation work before each experiment, and reduce the efficiency of the experiment

The invention relates to a novel inflatable metal particle research device. The device comprises a metal particle adding unit and an organic glass tank body, wherein the metal particle adding unit is located in the organic glass tank body; the metal particle adding unit comprises rotating handles, rotating sealing rings, a grooved electrode and a thin metal cover; the rotating sealing rings are used for guaranteeing the airtightness of the device; one rotating handle is connected with the grooved electrode through a rotating rod; the grooved electrode is connected with the thin metal cover and can cause relative sliding, so that metal particles are selected and added. With the adoption of the device, particles of various specifications can be selected and added without dismounting the sealing tank body and can be recovered after being researched. The whole research device mainly comprises the organic glass sealing tank body, the metal particle adding unit and a rotating distance-adjusting plate electrode; bases can be adjusted vertically. The device can be applied to research on the kinetic characteristic and the discharge characteristic of the metal particles in gas media.
Description
technical field [0001] The invention relates to a metal particle research device, in particular to a novel gas-inflatable metal particle research device. Background technique [0002] Gas insulated systems (GIS) are widely used in the field of high-voltage power transmission because of their excellent insulation performance and high operational reliability. In recent years, due to the continuous improvement of GIS grades, the insulating properties of GIS have become the focus of current GIS research issues. Metal particles are inevitably generated inside the GIS due to mechanical friction during production assembly and switching operations. These metal particles will move freely in the insulating cavity, thereby greatly reducing the insulation performance of the GIS and causing equipment breakdown accidents . [0003] For existing metal particle research devices, sealed tanks fixed by nylon screws are mostly used. Every time the particles are added, the device must be dis...
