Contact materials from W-Cu, W-Ag and WC-Ag systems obtained by spark plasma sintering technology to be used as electrical contacts for vacuum contactors were developed. The electrical contact materials have been obtained from homogenized powder composite mixtures of W-Cu (70-30, 60-40), W-Ag (70-30, 60-40), and WC-Ag (70-30, 60-40), by spark plasma sintering technology, in vacuum, under pressure...
In this paper, the authors aim to present the modelling, simulation and experimentation of an electromagnetic actuator used in the construction of vacuum contactors. In order to validate the numerical results obtained by computer simulation was performed and an experimental model. The role of the electromagnetic actuator is to achieve movement of the movable electrical contacts of the contactor with...
