Embodiment Construction

[0037] figure 1 is a perspective view of an open-air switchgear in the form of an earthing switchgear. The weather switchgear has a first support insulator 1 . The first support insulator 1 is shown here, for example, as a cylindrical first support insulator 1 , which is supported on a foundation. The longitudinal axis of the first support insulator 1 is oriented vertically. The first support insulator 1 is provided with a base plate 2 at its end protruding from the base. The base plate 2 is used for positioning the drive 3 . Furthermore, a drive box 4 is provided on the base plate 2 for actuating the drive device 3 . Devices for moving the drive are provided in the drive housing 4 . For example, an electric motor which converts electrical energy into a motion which is transmitted to the drive 3 can be located in the drive housing 4 . In addition, control and monitoring units, protective devices, locking devices, etc. can also be arranged in the drive box.

Abstract

The open-air switchgear has an open-air breaking interval and a first contact piece (5) and a second contact piece (6). The first contact piece (5) is movable relative to the second switch contact piece (6) by means of the drive device (3). The first contact piece (5) is arranged on the pivot arm (3b) of the drive device (3). The pivot arm (3b) is supported on the lifting transmission (3a).

Description

technical field [0001] The invention relates to an open-air switchgear with an open-air circuit breaker interval, which has a first contact piece and a second contact piece, wherein the first contact piece can move relative to the second contact piece by means of a driving device, and is arranged on a pivot of the driving device. on the swivel arm. Background technique [0002] Such an outdoor switchgear is known, for example, from a translation of the European patent document DE602005000144T2. The weather switchgear here is referred to as a pivotable earthing switch, which has a first contact piece and a second contact piece. The first contact is pivotable about a pivot fulcrum so that it is movable relative to the second contact. It is thus possible to form an open-air breaking interval between the two contact pieces. [0003] With known open-air switchgears, the pivot arm is formed by using two electrically conductive sub-elements that are oriented in alignment and fas...
