Einflußgrößen auf die Schweiß;kraft elektrischer Kontaktstücke in der Energietechnik

Parameters Influencing the Welding Force of Electric Contacts in Power Engineering . Main parameters influencing the accumulated frequency distribution of the welding force using bouncing contacts are: contact force, closing velocity, duration of bouncing, number of operations, testcurrent, phase displacement, frequency, moment of contact in relation to current zero at inductive load. The statistical distribution over a wide range of the values of the welding force is traced back on the relative position of the weldings on the surfaces of the contacts by means of a model. The influence of duration of bouncing, number of operations, contact force, opening velocity, value of test current and polarity on the welding force is described by accumulated frequency distribution plottings for various contact materials when making contact synchronous- and asynchronously.
