Abstract

The invention discloses an electrical switchgear for a power transmission network. The electrical switchgear comprises an electrical insulation support frame. The electrical insulation support frame comprises a base. An electrical insulation support column is arranged on the base. The electrical insulation support column comprises a plurality of insulation portions. The top end of the electrical insulation support column is connected with a driving head. The two sides of the driving head are connected with a first electrical insulation switch room and a second electrical insulation switch room. The first electrical insulation switch room is internally provided with a first switch point; and the second electrical insulation switch room is internally provided with a second switch point. Thedriving head is sleeved by a housing. The electrical insulation support column is internally provided with a kinematic chain and a drive rod. A driving device realizes switching of the first switch point and the second switch point through the kinematic chain and the drive. According to the electrical switchgear, a reliable electrical switchgear with a compact size can be produced.

Description

technical field [0001] The invention relates to an electric switch, in particular to an electric switch device for a power transmission network. Background technique [0002] Known electrical switching devices intended for use in electronic energy networks, especially when high voltages are used, are equipped with corresponding insulating parts to ensure a sufficient insulating path in the atmosphere. While as the voltage load of electrical switching devices increases, the number of electrical switching devices increases accordingly, thus causing equipment congestion, the object of the present invention is to provide an improved design of electrical switching devices in order to be able to produce reliable electrical switches with compact dimensions device. Contents of the invention [0003] The technical problem to be solved by the present invention is that as the voltage load of the electrical switchgear increases, the number of the electrical switchgear increases corre...
