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.

Claims (12)

1. A busbar module for a gas-insulated high-voltage switchgear assembly, comprising:

a housing;

three single-phase interfaces for the housing;

three phase conductors;

three busbar isolators, each busbar isolator having a corresponding input and a corresponding output;

three circuit breaker housings; and

three single-phase circuit breakers,

wherein:

the three phase conductors and three busbar isolators are arranged in the housing, each phase conductor being connected to the input of the respective busbar isolator associated with the phase conductor;

each single-phase interface is associated with a corresponding one of the busbar isolators at the output of the corresponding one of the busbar isolators; and

the three single-phase circuit breakers are each arranged in a respective separate circuit breaker housing among the three circuit breaker housings, each single-phase 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.

2. The busbar module as claimed in claim 1 , wherein the phase conductors are configured to be connected to the phase conductors of two further busbar modules.
