The armature and magnetic core are of laminated magnetic steel and have mating surfaces. At least one of the armature and magnetic core includes conductive weld or braze lines for integrally securing laminations together to define a conductive path proximate the mating surface to provide a shading coil.

摘要： A relay has a pair of fixed contacts, a pair of movable contacts adapted to be engaged and disengaged with the fixed contacts, and a solenoid having a coil and a plunger movable into and out of the solenoid, the plunger having an outer end operably connected to the movable contacts. The relay can maintain either of two stable positions in the absence of power to the coil, the two positions being a contact open or magnetically latched position and a closed or unlatched position. The invention is improved by a ball joint arrangement interconnecting the plunger and the movable contacts to enable wiping of the contacts on closure to remove thin film tarnish caused by oxidation of the Nobel metal contacts and to produce a torsional force which facilitates breaking of welds on opening. An insulator surrounds the movable contacts for cooling the arcing and magnetic fields are oriented with respect to the current in the contacts in a manner that applies a force on the current in the direction of the insulator.
摘要翻译：继电器具有一对固定触头，一对适于与固定触头接合和分离的可动触头，以及具有线圈和可移入和移出螺线管的柱塞的螺线管，该活塞具有可操作地连接的外端到可动触点。在没有线圈供电的情况下，继电器可以保持两个稳定的位置，两个位置是触点断开或磁性锁定位置以及闭合或解锁位置。本发明通过将柱塞和可动触点相互连接的球形接头装置来改进，以便能够在闭合时擦拭触点以除去由诺贝尔金属触头的氧化引起的薄膜损伤，并产生有助于在开口处破坏焊缝的扭转力。绝缘体围绕可动触头以冷却电弧，并且磁场相对于触点中的电流以在绝缘体的方向上对电流施加力的方式定向。

摘要： A system and method for preventing contact weld under various fault current conditions is disclosed. The system includes a contactor having stationary and movable contacts biased towards each other and switchable between an open and closed position. Energization of an electromagnetic coil engages the contacts creating an electric path for current flow through the contactor. Pulse width modulation is used to lower the power to the coil and maintain the contacts in the closed position. The contactor is equipped with safeguards to prevent contact welding. Under low fault currents, welding is prevented by contact material composition. Under intermediate fault currents, the contacts are blown open and remain open using magnetic components until the arc dissipates and the contacts have cooled sufficiently. Under high fault currents, the arrangement causes the contacts to blow open and separate the armature from the coil preventing re-engagement of the contacts until the coil is energized again.
