“…Movement of the piston is carried out by means of compressed gas. Gas leaves from the discharge chamber into receiver volume after break of a diaphragm (8). The cavity behind the piston plays a role of the shock-absorber since gas is squeezed out from it through a narrow slit between a tube (5) and the fluoroplastic cartridge (9).…”

The paper presents some results concerning electrophysical and gas-dynamics parameters of high-curent arc in axial blast discharge chamber. The experimental stand and numerical model were modified for axial gas flow type. Some design changes are described in the paper. The experiments were carried out for gas pressures of 1.0-6.0 MPa with current amplitude of 25-150 kA. The current half-period was of 1.0-10.0 ms. The contacts moved apart to the distance of 3-4 cm due to gas pressure boost in the chamber. OpenFOAM package with the library swak4foam was used for numerical simulation.

This article is devoted to a development of a mathematical model of plasma processes in a discharge chamber of a multi-chamber arrester operating under reduced pressure. The results obtained using this model will make it possible to develop recommendations on modifying the design of multi-chamber arresters for operation in conditions of mountain areas.<br />A composition, thermodynamic and transport properties of plasma for the two-temperature model were calculated on the basis of the data on the materials of the discharge chamber and on the basis of the experiments performed earlier.<br />The paper presents the results of calculations i.e. distributions of discharge voltage and electrical conductivity on time at various pressures. A comparison of obtained results was carried out.

Protection of important energy facilities from direct lightning impact requires the creation of special devices for lightning protection in particular multi-chamber arresters. To improve the efficiency of multi-chamber arrester operation it is necessary to perform mathematical simulation of the physical processes that take place inside such devices. To develop a mathematical model of arc discharge it is necessary to know the thermodynamic and transport properties of the plasma depending on temperature and pressure. In the article the dependences of the thermodynamic and transport properties of plasma in a multi-chamber arrester were obtained for the two-temperature plasma model for the electron temperature range Te = 300–30 000 K, the nonequilibrium degree range is 1–5, and the pressure range p = 0.3–1 atm.
