## Abstract

An exemplary high-current switching arrangement in a generator duct arranged between a generator and a transformer is disclosed. This arrangement includes a pole frame which can be positioned on a base surface, a breaker pole of a generator circuit-breaker which is secured to the pole frame, and a drive which is secured to the pole frame. The breaker pole includes an active component arranged along an axis designed for the conduction and interruption of high currents and which incorporates a power switching point, with two axially spaced current terminals. The drive is arranged on a first of two end faces of the pole frame, and includes a linkage mechanism that transmits power from the drive to the power switching point.

## Claims

### Claim 1

A high-current switching arrangement for incorporation in a generator duct arranged between a generator and a transformer, the arrangement comprising:
a pole frame which can be positioned on a base surface;
a breaker pole of a generator circuit-breaker which is secured to the pole frame; and
a drive which is secured to the pole frame,
wherein the breaker pole is provided with an active component arranged along an axis designed for conduction and interruption of high currents and which incorporates a power switching point, the breaker pole having two axially spaced current terminals for an electrically-conductive integration of the active component upon incorporation of the high-current switching arrangement in a circuit path of a high-voltage conductor in the generator duct, and
wherein the drive is arranged on a first of two end faces of the pole frame and is oriented transversely to the axis, and a linkage mechanism transmitting power from the drive to the power switching point is routed through the first end face of the pole frame to the active component.

### Claim 2 (depends on 1)

The high-current switching arrangement as claimed in claim 1, wherein the drive is arranged below a first of the two current terminals of the active component.

### Claim 3 (depends on 1)

The high-current switching arrangement as claimed in claim 1, comprising:
a box-type enclosure that accommodates the active component, the enclosure having two openings incorporated into faces of the enclosure, the two openings are arranged opposite each other and allow the high-voltage conductor of the generator duct can to be routed therethrough,
wherein the drive is positioned below a first of the two openings in the enclosure, and the linkage mechanism is routed to the active component arranged in an interior of the enclosure.

### Claim 4 (depends on 3)

The high-current switching arrangement as claimed in claim 3, wherein at least part of a base of the enclosure is detachably connected to the pole frame and closes a mounting aperture which, after installation of the high-current switching arrangement and an opening of the mounting aperture, will permit access from a surface of the base to the interior of the enclosure.

### Claim 5 (depends on 4)

The high-current switching arrangement as claimed in claim 4, wherein the pole frame includes support legs.

### Claim 6 (depends on 4)

The high-current switching arrangement as claimed in claim 4, wherein the base of the enclosure is perforated in a grid pattern.

### Claim 7 (depends on 1)

The high-current switching arrangement as claimed in claim 1, wherein the linkage mechanism includes a twin-arm reversing lever which is arranged to pivot on a fixed point of rotation, together with two push rods, wherein a first end of the first push rod is coupled to a first arm of the reversing lever and a second end of the first push rod is coupled to a lever connected to an insulating shaft that is routed to the power switching point from below in a rigid arrangement, and wherein a first end of the second push rod is coupled to a second arm of the reversing lever and a second end of the second push rod is coupled to a drive element of the linkage mechanism that is routed in an axially displaceable manner through the pole frame.

### Claim 8 (depends on 3)

The high-current switching arrangement as claimed in claim 3, wherein, on the first end face of the pole frame, at least one additional drive is arranged with a non-positive connection to a switching device arranged in the enclosure, the switching device being configured as a disconnector, grounding switch, or starting switch for the high-current switching arrangement.

### Claim 9 (depends on 3)

The high-current switching arrangement as claimed in claim 3, wherein, on a second end face of the pole frame, opposite the first end face, at least one additional drive is arranged with a non-positive connection to a switching device arranged in the enclosure, the switching device being configured as a disconnector, grounding switch, or starting switch for the high-current switching arrangement.

### Claim 10 (depends on 8)

The high-current switching arrangement as claimed in claim 8, comprising:
at least two phase-segregated breaker poles including at least two pole frames, each of which carries one of the breaker poles and one drive.

### Claim 11 (depends on 8)

The high-current switching arrangement as claimed in claim 8, comprising:
at least two phase-segregated breaker poles, wherein in the pole frame carries the at least two breaker poles.

### Claim 12 (depends on 11)

The high-current switching arrangement as claimed in claim 11, wherein the drive transmits power to the at least two breaker poles via a single linkage mechanism.
