Embodiment Construction

[0019] The invention will be further described below in conjunction with the accompanying drawings. The invention mainly consists of a DC glow discharge mechanism and supporting circuits. The discharge mechanism at least includes a low-voltage discharge tube 2 with built-in discharge electrodes 1, 4, a built-in test probe 3, and an air suction port 18 and an air filling port 19, which are filled with air, hydrogen, carbon dioxide, etc. , At least one working gas in nitrogen. The air suction port 18 is connected to a vacuum pump, and can make the vacuum pressure in the low pressure discharge tube 2 be 10Pa-400Pa; the gas charging port 19 is connected to the gas source of the working gas through a flow meter. Discharge electrodes 1 and 4 that can move within the axis range of 50-150mm are placed at both axial ends of the low-pressure discharge tube 2 . The two ends of the low-voltage discharge tube 2 are fixed by two brackets, and two water-cooling supports connected to the ci...

Abstract

The invention is a test device for researching a direct current (DC) glow plasma, mainly comprising DC glow discharge mechanism and supporting circuit, where the glow discharge mechanism at least comprises a low voltage discharge tube embedded with discharge electrodes, embedded with test probe and provided with gas intake and gas charging inlet as well as charged with at least one operating gas of air, H2, CO2, and N2, the gas intake is connected to a vacuum pump and able to keep the vacuum in the low voltage discharge tube at 10Pa-400Pa, and the gas charging inlet is connected through a flowmeter to an operating gas source, two axial ends in the low voltage discharge tube are provided with discharge electrodes moving in the 50-150 mm range of the axis and two ends of the low voltage discharge tube are fixed through two brackets and provided with two water cooled seats each connected through circulating water to a circulating pump; and the invention has characters of compact structure, convenient to operating, very high cost/trade-off, suitable to make batch production, beneficial to spreading, etc.

Description

technical field [0001] The invention relates to an experimental device for studying the characteristics of DC glow plasma, which belongs to DC glow plasma [0002] technology field. Background technique [0003] Plasma technology is an important technology related to national energy, environment and national defense security. DC glow plasma technology is widely used because of its simple structure and low cost. However, in China, the research and teaching of glow plasma technology lag far behind the application of glow plasma technology in engineering. Higher Institute of Technology The school lacks training on plasma theory and practice in the personnel training process. The main reason for this phenomenon is that plasma equipment is expensive and basically needs to be imported. The price is generally between 500,000 and 5 million yuan. Research institutes can't care about it, and ordinary research institutes and colleges and universities basically have no chance to get t...
