Abstract

Electromagnetic arc extinction apparatus comprises an arc chamber 19 of insulating material and having an axial channel 22 and electrodes 20, 21 aligned with the axis of the arc chamber 19 and adapted to form a quenching arc 23 in the form of a helix. The cavity of the arc chamber is bent along a helix to cause the quenching arc 23 to be moved in a radial direction, the pitch of the cavity is at least 10 times lesser than the diameter of the arc chamber measured over the cross-section thereof. Conductor plates 16, 17 allow movement of arc roots. The apparatus of the invention is suitable for use on any desirable alternating- or direct-current circuits and can find use in high-voltage heavy-current switchgear including circuit breakers and fuses. <IMAGE>
