    摘要: A gas-insulated, high-voltage apparatus wherein arcs can develop includes an encapsulation and at least one electrical conductor made of aluminum or an alloy thereof which is held in spaced relation to the encapsulation by insulators. A surface is arranged at the conductor at locations thereof subject to the greatest arc activity. The surface faces the encapsulation and is defined by an electrically conductive, arc-resistant material. An excessive stress and endangerment of the encapsulation because of arc action is thereby prevented.

    摘要: To check the presence of operating vacuum in vacuum switches, high voltage can be applied between the contacts at a given contact spacing and the dielectric strength can be tested. According to the invention, the procedure for vacuum monitoring is that a contact spacing (h) below the nominal stroke of the vacuum switch is selected and that the X-radiation generated at this contact spacing (h) and high voltage (U) in vacuum due to the field electron emission between the contacts by the contact surfaces acting as anode is acquired and evaluated as proof of the presence of operating vacuum inside the switching tube. This method can preferably be applied to encapsulated vacuum switching tubes, in particular to SF.sub.6 -insulated switching facilities. Associated with the vacuum switching tube (15) in the associated equipment is an X-ray detector, preferably a Geiger-Muller counter, which is connected to the high-voltage unit (25) via an evaluating circuit (30 to 50) which serves for the determination and indication of the operating vacuum and shuts off the high-voltage unit (25) to minimize the X-ray dose. Due to the X-ray emission, which is stopped long before reaching impermissible values, the presence of vacuum can be positively verified.
