Zusammenfassung: | An overvoltage arrester for a metal-clad high-voltage switching system is provided in a separate housing which is filled with an insulating heavy gas. The separate housing contains a spark gap arranged in a heavy gas atmosphere which is the same as the insulating heavy gas filled within the metal encapsulation for the switching system. The separate housing is connected with the encapsulation via a valve-controlled gas line. The overvoltage arrester is particularly well suited for metal-clad high-voltage switching systems that are insulated by sulfur hexafluoride. |
