Transformer having secondary-voltage addition in accordance with a system which is defined in magnitude and sequence

摘要

Transformers having secondary windings, where the magnitude ratio and sequence is defined in the addition of tapped voltages - it being possible to select the magnitude at will. The ratio sequence of the secondary windings in volts is = 1/5/2/4/3/10 or, for example 2/10/4/8/6/20 If required, the 6th winding = 10 can also be omitted. All the voltage magnitudes can be tapped off from this secondary winding system in accordance with the total addition of the secondary windings, stepped to the magnitude of the smallest ratio step; for example 2 V = value 1, 2-30 V tapped voltages in 2 V steps, 20 V and 26 V can be tapped off by changing over in the sequence of the windings.
