摘要： A control system may include a processor that may receive a first dataset associated with a current received at a load device coupled to a relay device. The processor may also determine harmonics data associated with the current and determine a switching profile to control moving a first armature of three armatures in the relay device based on the harmonics data. The switching profile is configured to control movement of the first armature between a first position and a second position, and wherein the switching profile comprises a firing angle for moving the first armature with respect to an electrical waveform, a second armature, and a third armature. The processor may then control a current provided to a relay coil of the relay device based on the switching profile, such that the relay coil causes the first armature to move.

摘要： A switching device, for a wye-delta switch in a multiphase motor each phase having one motor winding having a connection pair and contact device (CD), has an electromagnetic drive for drive axle movement between three axial positions, the CD having first and second motor winding connection contacts (MWCC), phase connection contact (PCC), and movable contact bridge (MCB) coupled to the drive axle and movable thereby into the three positions. In position-1, axially between positions-2/3, the MCB is open—no CC is connected to another CC by the MCB; in position-2, the MCB is in ‘wye’ contact position—the MCB connects the PCC to the first MWCC, and the second MWCC is connected to the second MWCC of all other CDs using the ‘wye’ coupled to the drive axle; and in position-3, the MCB is in a ‘delta’ contact position—the MCB connects the FCC to the first and second MWCC.

摘要： Electrical equipment coupled to a printed circuit board provides insulation ribs projecting from a face between terminal plates provided on an upper face of the electrical equipment. The insulation ribs are inserted into oblong holes of the printed circuit board when the electrical equipment is coupled to the printed circuit board. As a result, insulation distances, namely creepage distance, between the terminal plates are along the height of the insulation ribs projecting from the upper face of the terminal plates.

The crossbar and the movable core are supported pivotally on the rigid frame. One of the polygonal bars is supported rotatably at the opposite ends thereof in bearings provided on a stand, while the other polygonal bar is urged upward by springs so that the rigid frame will swing to bring the movable contacts into contact with the fixed contacts, respectively, when the operating coil is energized to attract the movable core to the fixed core.
