• On the Secondary Current Measurement of the Three Phase Frequency Type Resistance Welding Machine

抄録

At present the most difficult problem in the three phase frequency converter type resistance welding machine is secondary current measurement.<BR>In this paper we discussed some questions on next two typical measuring methods, which seem to be most useful up to date, series resistance voltage drop method and toroidal coil method.<BR>Results obtained are as follows ;<BR>(1) For series resistance use, the height of pulsating component measured is higher than actual current. For toroidal coil use, <BR>(2) the influence of coupling position between welder lower arm and coil does not appear.<BR>(3) current magnitude is measured smaller than actual current value, and the errer is approximately proportional to welding time.
