Abstract
A stored-energy mechanism for a high-voltage circuit-breaker pole filled with an insulating gas with a drive rod, which transmits the drive movement to an interrupter unit by thrust or traction and which can be driven through a drive crank attached to a drive shaft, and with an opening spring coupled to an opening crank attached to the drive shaft and with a closing spring driving a closing crank attached to the drive shaft. It is provided that the closing crank and the opening crank are arranged outside the insulating gas chamber. The drive crank is arranged inside the insulating gas chamber, a carrier block seals the chamber filled with insulating gas against the outer chamber, the drive shaft traverses a housing wall of the carries block in a gas-tight manner, and the carrier block forms an end support for the closing spring and the opening spring.
