摘要:
An electric high-voltage power switch has two contacts and at least one gas outlet for quenching gas heated by the arc generated between the contacts. A cooling device is provided for cooling the quenching gas. The cooling device is formed of a metal body with through-holes arranged in the flow path of the quenching gas. An insulating component impermeable to the quenching gas, is fitted in the gas outlet in front of the metal body viewed from the contacts and consists of a material (PTFE) releasing a quenching gas at high temperatures. The insulating component is sufficiently distanced from the metal body for the quenching gas to be able to pass through the through-holes substantially over the entire surface of the metal body.

A metal-sheathed high-voltage line with a high-voltage conductor and a metal sheath surrounding it coaxially has at least one securing element for a disk-shaped insulating support which has a first and second ring), each of which is concentric with the high-voltage conductor and each of which has a web projecting radially with respect to the longitudinal axis of the high-voltage line, where the insulating support is secured between the webs of the rings. The rings are jammed tightly by a wedge action on the high-voltage conductor.

On a high-voltage power switch there is provided a shaft for transmitting a rotary motion through a wall. A deflection lever is disposed on the shaft. The shaft and the deflection lever are part of a kinematic chain. For adjustment of the deflection lever in its position on the shaft, the deflection lever has an adjusting device.
