“…The electromagnetic forces in the law of conservation of momentum are negligible, and in the law of conservation of energy, the contribution of the electromagnetic component is absent (the current is zero), therefore, they are neglected. The mathematical model was verified on the experimental stand of the IEE RAS [9][10][11] and showed a close agreement between the calculated and experimental data.…”

According to modern trends, the interrupting performance and reliability of HV gas blast circuit breakers should be increased with transition to SF6-free technologies. Controlled switching is a promising method to reach it. However, high level of failure of the operating mechanism (drives) hinders this goal and would also result in the serious accidents. Some problems of the controlled switching application are discussed in the present study. A method of a short time gas pulse under high pressure – synchronous gas injection – is proposed to achieve the necessary cooling-heating balance in a thermal mode considering benefits and drawbacks of the controlled switching. The controlled pulsed injection should be introduced to the plasma region before current zero to decrease pre-zero arc conductivity and achieve the effective arc-gas interactions immediately after current zero. In the study the performance of the suggested approach is verified by numerical simulation and empirical relationships with a model mono-flow arc quenching device. The research confirms the synchronous gas injection has a wide perspective to increase breaking capacity of realistic circuit breakers in high voltage levels, especially for short-circuit interrupting.

“…Earlier in our laboratory, the stand for research of lightning protection systems [15] and the stand for studying arc and erosive processes in high-current gas blast breakers [16,17] had been built. In the development of researches [16][17][18][19] for this theme it was carried out the modernization of the systems. And it was designed a new axial blast discharge chamber.…”

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.
