ABSTRACT:
An integrated contact for power switchgear, its arc proof component, magnetic field generating component and conductive component are set in an open container. The conductive component and the magnetic field generating component are mutually combined and set at the bottom of the container, the arc proof component is set on top of the combination of the conductive component and the magnetic field generating component. The conductive component passes through the center of the container, and from top to down, it equally divides the container; the magnetic field generating component is isolated by the conductive component and set at the other part of the container. The contact surface of the invention has multiple pole axial magnetic fields, the contact is suitable used for integrated contact for interrupting high volume current in arc extinguished chamber of vacuum interrupter. The invention belongs to electrical equipment field.
