Abstract

A gas-blast power switch for high voltages incorporating a housing filled with gas within which there is arranged a series connection of a power interrupter and a disconnecting switch, a pump device equipped with a pump cylinder and pump piston and positively connected with a switch drive. The pump device during cut-off conveys gas into the power interrupter and during cut-on sucks-up gas. The housing is subdivided into two compartments separated by a wall, one compartment housing the power interrupter and the other the disconnecting switch. The power interrupter is formed of a ring contact pair surrounded by a ring gap nozzle arranged in the wall, the ring contact pair in its open state receiving at least the 2.5-fold phase voltage of the high voltage network, the gap of the ring gap nozzle being bounded at least at one side by an electrical insulating material, the disconnection path of the disconnecting switch being designed at least for the test voltage of the power interrupter, and the contacts of the power interrupter separate during cut-off between 20 and 50 percent of the pump piston stroke and the contact of the disconnecting switch separate at the earliest during 80 percent of the pump piston stroke.
