摘要

The electrical switching device has an interrupter unit for interrupting and connecting an electrical line. The interrupter unit is connected with other closed interrupter unit. The electrical flashovers produced appear as electric arcs by connecting or interrupting the electrical conductor in the later interrupter unit. The later interrupter unit is switched, when connecting the electrical line before the former interrupter unit. The later interrupter unit is switched, when connecting the electrical line before the former interrupter unit and when interrupting the electrical line, after the former interrupter unit. An independent claim is also included for method for switching an air-insulated grounding switch of electrical line.
