Abstract:
PROBLEM TO BE SOLVED: To provide a closing resistor arrangement or a high voltage circuit breaker to enable two or more times of switching even in a comparatively high voltage power supply system. SOLUTION: This closing resistor 18 for the high voltage circuit breaker has a large number of resistor elements 70 and a large number of cooling elements 60. The cooling elements 60 are arranged in series with one another, and are electrically connected in series with one another. The resistor elements 70, which electrically connect the electrical cooling elements with one another, are each connected between two cooling elements 60 arranged in series.

Abstract:
The method is provided for manufacturing a perforated sheet-like high-voltage insulating spacer (2) for a high-voltage component, which component comprises a field grading condenser core with the spacer which is wound in spiral form around an axis (A), with electrically conducting layers (3) which are inserted between successive windings of the spacer, and with a polymeric matrix which penetrates the spacer (2) and which embeds the spacer and the layers(3). The method comprises at least steps as follows: an electrically insulating tape (2) is moved in a running direction (R), a pattern (P) of parallel extended cutting lines (21, 22) is inserted into the tape, and the patterned tape is expanded at right angle to the cutting lines (21, 22) in order to form a spacer with a perforated three-dimensional lattice structure (LS). The combined effect of cutting a tape and expanding the cutted tape allows the formation of spacers with a manifold of sizes which exceed the size of the tape in function of manufacturing parameters, in particular in function of the configuration of the pattern and of the magnitude of the expansion.
Abstract:
Ein Stromwandlermodul für eine Schaltanlage umfasst ein Gehäuse zur Aufnahme von drei gasisolierten Nominalleitern sowie eine erste Anschlussgruppe mit drei ersten Nominalleiter-Öffnungen zur Aufnahme von jeweils einem der drei Nominalleiter, wobei die drei ersten Nominalleiter-Öffnungen flächenmäßig in einer ersten Ebene angeordnet sind. Das Modul umfasst weiter eine zweite Anschlussgruppe mit drei zweiten Nominalleiter-Öffnungen zur Aufnahme von jeweils einem der drei Nominalleiter, wobei die drei zweiten Nominalleiter-Öffnungen flächenmäßig in einer zweiten Ebene angeordnet sind, die zur Ebene der drei ersten Nominalleiter-Öffnungen senkrecht steht, und eine erste Gruppe von drei Stromwandlern die in einem ersten Bereich des Gehäuses bereitgestellt sind, wobei das Gehäuse einen gemeinsamen Gasraum zur Aufnahme eines Isoliergases und der drei Nominalleiter bildet.
Abstract:
The resistor arrangement (18) has several connectors (24-27) arranged in series with one another and at least one of the resistors being arranged between at least two connectors, for serial electrical connection of the connectors. The connectors which are electrically connected to one of the resistors are in the form of a cooling element for dissipating heat from the resistor. The resistors are arranged in parallel to one another between two cooling elements and are connected electrically in parallel with one another by the cooling elements.
