Abstract
The invention relates to a gas-insulated high-voltage switchgear, comprising at least one bus bar with three phase conductors, whereby each phase conductor is connected to the input of a respectively provided bus bar section. The phase conductor and the bus bar section are arranged in a three-phase bus bar module with three single-phase power switches, each arranged in a separate power switch housing and each bus bar section is connected at the output therefrom to a respectively provided power switch.
Claims18
A gas-insulated high-voltage switchgear assembly, comprising:
- a three-phase busbar module including:
- a housing;
- three busbar isolators arranged in the housing, each busbar isolator having a corresponding input and a corresponding output;
- and
- three phase conductors arranged in the housing, each phase conductor being connected to the input of a respective busbar isolator associated with the phase conductor;
- and
- three circuit breaker housings;
- three single-phase circuit breakers, which are each arranged in a respective separate circuit breaker housing among the circuit breaker housings, each circuit breaker including a corresponding input side and a corresponding output side, each busbar isolator being connected at the output of the busbar isolator to a respective one of the three single-phase circuit breakers;
- and
- at least one splitter module, each splitter module including a corresponding housing distinct from the housing of the busbar module, and each splitter module including three phase conductors, at least one three-phase interface for the splitter module housing, and three single-phase interfaces for the splitter module housing,
- wherein, for each splitter module, each phase conductor of the splitter module is guided by the at least one three-phase interface to a corresponding one of the single-phase interfaces.
A splitter module for a gas-insulated high-voltage switchgear assembly, comprising:
- three phase conductors;
- at least one three-phase interface;
- and
- three single-phase interfaces,
- wherein each phase conductor is guided from the at least one three-phase interface to a corresponding one of the single-phase interfaces,
- wherein the at least one three-phase interface and the three single-phase interfaces each have a cross-sectional plane associated therewith, and
- wherein the cross-sectional plane associated with the at least one three-phase interface is substantially parallel to the cross-sectional planes of the single-phase interfaces.
A splitter module for a gas-insulated high-voltage switchgear assembly, comprising:
- a housing;
- three phase conductors arranged in the housing;
- at least one three-phase interface for the housing;
- and
- three single-phase interfaces for the housing,
- wherein each phase conductor is guided from the at least one three-phase interface to a corresponding one of the single-phase interfaces,
- at least one current transformer arranged in the housing and respectively associated with each phase conductor.
