Problems solved by technology

However, the above control mainly has an on / off control function
What is disclosed does not clearly disclose whether the controls include any possibility for more complex controls
In addition, it is clear that there is no means to allow any feedback on the operation of the circuit breaker
Therefore, the above-described means are not suitable for eliminating or reducing the need for local activities of the type described above

Embodiment Construction

[0065] Fig. 1 schematically illustrates the elements of an electrical switching device. It includes a circuit breaker cavity 1, a driving device 2 and a driving rod 3. A fixed contact part 4 and a movable contact part 5 are provided in the circuit breaker cavity. Each contact part is respectively connected with the conductor. Under normal circumstances, the two contact portions 4, 5 are in contact with each other and the current flows from one contact portion to the other contact portion through the switching device. When the current is interrupted for some reason, such as a fault short circuit current, the movable contact part 5 is moved away from the fixed contact part 4 at a high speed. Therefore, an arc is generated between the contact parts at first, and the arc disappears immediately after the contact parts are separated by the insulating gas. After that, when the current is closed, the movable contact portion 5 moves in the direction of contact with the fixed contact portio...

Abstract

The invention concerns a switching device system including at least one switching device, signal means and control means. Each switching device includes at least one mobile contact part, an electric motor and, coupling means. The coupling means is arranged to transfer motion from the electric motor to the mobile contact part. The control means is arranged to control the switching device. According to the invention the control means is at least partly remotely located from the switching device. The signal means transmit signals from the switching device to the remotely located control means and vice / versa. The signals represent real-time data and / or off-line data. The invention concerns also a switching device, control means and methods related to the invented system as well as computer program products for such system and electric power system being provided with such system.

Description

Technical field [0001] The present invention generally relates to a switchgear system, its components and the related methods. More precisely, the present invention relates to the following aspects of the above-mentioned system.
