Horseshoe-shaped longitudinal magnetic electrode structure of high-voltage vacuum arc-extinguishing chamber

The invention discloses a horseshoe-shaped longitudinal magnetic electrode structure of a high-voltage vacuum arc-extinguishing chamber. An insulating layer is arranged between every two adjacent horseshoe iron sheets in a horseshoe iron sheet group of a positive contact and a horseshoe iron sheet group of a negative contact. According to the invention, the insulating layer is made of a ceramic material, the insulating layer enables two adjacent horseshoe iron sheets to be insulated from each other, and magnetic conductive loops between the two horseshoe iron sheets are not contacted any more, so that the eddy current on the horseshoe iron sheets is reduced, the energy loss is further reduced, and the strength of a longitudinal magnetic field is increased, thereby improving the breaking performance between the positive pole contact and the negative pole contact; and the insulating layer has no influence on other structures and assembly processes. 本发明公开了一种高电压真空灭弧室马蹄形纵磁电极结构，所述正极触头和负极触头的马蹄铁片组中的相邻的两个马蹄铁片之间均设置有绝缘层
