Gas blast circuit breaker drive leverage - converts vertical movement of insulating rod into horizontal movement of two pistons compressing gas

摘要

The switch has a fixed compression cylinder with a fixed nozzle at one end, and with a piston for gas compression. The switch consists of two breaks, one behind the other, and is mounted on a hollow insulator. A transmission is provided between the two breaks, which converts the pull of an insulating rod in the insulator in two horizontal pressures. The transmission (2) has two pressure rods (8, 8') connected at their top ends (3) with the insulating rod (7). Their top ends (3) are so guided (37) that only vertical movement is possible.
