Definitions
- the invention relates to a provided with selection tap changer with a poling circuit for uninterrupted control of a control transformer.
- Stepped transformer in which the reversing contacts of the tap changer are designed as changeover contacts.
- the tap winding of the corresponding tapped transformer is briefly electrically isolated from the main winding during operation of the preselector. It assumes a potential that results from the voltages of the neighboring windings as well as the
- DE 32 24 860 A describes a similar arrangement to a tap changer in which - as shown in Figure 1b - also a Polungswiderstand is in turn articulated at the center of the tap winding.
- JP 55-133515 A and DD 47965 B1 It is known from JP 55-133515 A and DD 47965 B1 to have a preselected one
- Step switch with poling circuit for uninterrupted control of a control transformer on the control winding voltage-dependent resistors to protect against overvoltages when switching the preselector to order.
- Polarity switch is connected to the load dissipation. Characterized the step winding is articulated during the preselection circuit to a defined potential.
- the object of the invention is therefore to provide a tap changer with an improved poling circuit, which entails a significantly reduced arcing at preselection.
- the general inventive idea which applies to both embodiments in the independent claims, is to provide two separate polarity resistors which are connected to the beginning and to the end of the step winding.
- two polarity resistors form a bypass for the capacitive current; the capacitive current commutes from one side to the other side - unlike the state of the art, it does not have to be switched off by the preselector, ie. H. to be interrupted. As a result, significantly less arcing occurs.
- Figure 1 shows an arrangement according to the prior art
- Pole arrangement will be explained. Shown is a main winding 1 and a tap winding 2 of a tapped transformer. At the tap winding 2, a tap changer is connected, which has a voter 3. The selector 3 first selects the new one before switching
- Winding tap the step winding 2 before, to be switched to.
- the switching itself is done by a known diverter switch 4 of the tap changer, which will not be discussed in detail here.
- the tap changer has a preselector 5, by the beginning or end of the tap winding 2 to the end of the.
- Main winding 1 can be switched.
- the actual poling circuit consists of a to the center 6 of the tap winding 2 hinged polarity resistor 7, which is either directly connected to the load discharge line 9 or, as shown here, via a polarity switch 8 is only briefly connected to the load discharge 9.
- FIG. 2 shows a first embodiment of the invention
- a first polarity resistor 11 is provided according to the invention at the beginning of the step winding 10 2, the means of a first
- Polungsschalters 12 is in communication with the load dissipation.
- a second polarity resistor 14 is further provided at the end 13 of the step winding 2, which is in turn connected to the load discharge line 9 via a second polarity switch 15.
- the two polarity switches 12, 15 are only briefly turned on before the start of the operation of the preselector 5, so that only briefly the beginning 10 and the end 13 of the tap winding 2 are hinged to a defined potential.
- Figure 3 shows a second embodiment of the invention in which no polarity switches are provided. Rather, here are solid and permanently at the beginning of the 10 stage winding 2 a first
- both embodiments can be realized in single-phase tap changers without much effort.
- the polarity resistors 11, 14 can be designed asymmetrically in both embodiments, so that the specific polarity conditions can be easily adjusted or evened out on the respective transformer.
