A study into statistical regularities of extinction of a DC electric arc in an axisymmetric magnetic field

A statistical investigation is performed of the extinction of a 30–350 A electric arc in a vacuum gap, in which permanent magnets are used to generate an axisymmetric magnetic field with different ratios between the radial and axial components of magnetic field induction. Dependences are given of th...

Description
Summary:A statistical investigation is performed of the extinction of a 30–350 A electric arc in a vacuum gap, in which permanent magnets are used to generate an axisymmetric magnetic field with different ratios between the radial and axial components of magnetic field induction. Dependences are given of the duration of stable arcing and limiting interruption currents on the magnetic field induction and on the size of contact gap.
