Definitions
- the invention is therefore based on the object of specifying a circuit for high-voltage windings of transformers and inductors for voltage control and damping of voltage pulses, which is compared to that described in p.g. Solution specified in EP-A-0 078 985 enables a further simplification and a further improvement of the economy for the entire winding structure.
- the circuit according to the invention is very advantageous, since the wiring of only one or less stressed groups of windings further reduces the effort required to secure a winding arrangement against overloads by voltage pulses, and in particular the space requirement is also reduced.
- the coarse step winding 13 is designed as a single-layer winding with two interwoven winding conductor strands.
- a voltage-dependent resistor 16 is connected in parallel to a winding conductor strand. This voltage-dependent resistor 16 limits the voltage occurring in the coarse step winding 13, in particular voltages induced in the coarse step winding 13, in particular by high-frequency voltage pulses.
- the voltage-dependent resistor 16 dampens voltage pulses Voltage vibrations in electrically coupled windings.
- the coarse step winding 13 is designed as a two-layer winding and the voltage-dependent resistor 16 is connected in parallel with one winding layer.
- the undervoltage winding 17 is constructed from two winding parts which are electrically connected in series. One of these winding parts is arranged spatially between the high-voltage winding 12 and the fine-stage winding 14. A coarse step winding 13 is not provided in this embodiment.
- a voltage-dependent resistor 16 is connected in parallel with the winding part of the undervoltage winding 17, which is located spatially between the high-voltage winding 12 and the fine-stage winding 14. This in turn limits the voltage in the connected winding part and dampens voltage vibrations in all electrically coupled windings and winding parts. This limiting and damping effect of the voltage-dependent resistor 16 is also transmitted to the high-voltage winding 12 and the fine-stage winding 14 by the close inductive and capacitive coupling.
- inventive circuitry of groups of windings which are subject to high electrical stress, which represent winding parts, is not only advantageous in the exemplary embodiments mentioned, but is also expedient if, within a winding arrangement, parts of the winding are stressed by electrical voltage significantly more than other parts due to uneven voltage distribution.
