Abstract

Various embodiments of the teachings herein include a grid influencing system for a power supply grid comprising: a current-conducting grid influencing component; and a vacuum circuit breaker including a vacuum circuit breaker tube containing an at least partly integrated pre-arcing device for actively generating an arc between two contacts.

First claim

What is claimed is:

1. A grid influencing system for a power supply grid, the system comprising:
a current-conducting grid influencing component including a unified power flow controller;
a vacuum circuit breaker including a vacuum circuit breaker tube containing an at least partly integrated pre-arcing device for actively generating an arc between two contact surfaces; and
an ignition electrode for igniting the arc along an arc current path;
wherein the unified power flow controller comprises:
a first transformer to tap energy off of the power supply grid;
and
a second transformer influencing an impedance of the power supply grid by altering a phase angle between a current of the power supply grid and a voltage of the power supply grid.

2. The grid influencing system as claimed in claim 1 , wherein:
the two contact surfaces are movable translationally with respect to one another; and
the arc current path and a continuous current path geometrically are separated from one another at least in a contact region.

3. The grid influencing system as claimed in claim 2 , further comprising
a moving contact surface and a fixed contact surface; and
a contact pin operable to mechanically couple a drive unit to the moving contact surface;
wherein the contact pin is mechanically coupled to a pre-arcing contact movable translationally along a switching axis independently of the moving contact.

4. The grid influencing system as claimed in claim 1 , wherein the contact surfaces in a closed state of the circuit breaker are arranged with no contact with respect to one another.
