    摘要: A magnetic flux concentrator shield is disclosed for use with magnetic flux sensors in an overload relay for multiple pole electromagnetic contactor applications. The magnetic flux concentrating shield has slotted layers of laminated members. The layers have a series of pole shielding slots which concentrate magnetic flux generated by conductors carrying current through conductor apertures in each layer. Magnetic flux sensors are positioned within air gaps within each pole of the shield. By shielding the generated magnetic flux from reaching the magnetic flux sensor of another pole, the pole shielding slots minimize cross pole magnetic flux sensor interference.

    摘要: The current interchange includes a housing disposed on a high voltage circuit interrupter. The movable switch contact extends into the housing with a guide member attached to the end of the movable switch contact. The housing includes a base attached to one of the terminals of the interrupter and includes a pair of guide rods extending into the housing for guiding engagement with the guide member. A pair of electrical cables extend helically around the guide rods and have one end attached to the base and another end attached to the guide member to provide an electrical path between the movable switch contact and the terminal. The electrical cables produce an axial magnetic field which maintains the metallic vapor produced by the interruption of the circuit between the contacts to reduce the transport of ions from the gap and reduce the current chop.
