    摘要: A gas filled circuit breaker comprises a hermetically sealed tank (1) formed by a surrounding wall (1b) filled with an insulating gas, at least one pair of contacts being arranged inside the surrounding wall. Contact operating means include force generating means which generate a force for operating the contacts and are arranged outside the surrounding wall (1b, 1c), and a rotational shaft (2) connected to the force generating means at the outside of the surrounding wall and extending to the inside thereof so that the force is transmitted through the surrounding wall to the inside thereof. Seal means are arranged between the surrounding wall (1b, 1c) and the shaft (2) to keep a hermetic seal therebetween. At least two bearings support the shaft (2) in a rotatable manner. Connecting means (15) for transmitting the force from the shaft (2) to at least one of the contacts to be moved in relation to the other are connected to the shaft (2) between the bearings.

    摘要: An operating device for a gas circuit breaker includes an operating piston 3 received in an operating cylinder 2 so as to reciprocally move between a first position 3a and a second position 3b, the operating piston 3 dividing an internal space of the operating cylinder 2 into a first chamber 2a and a second chamber 2b. The operating piston 3 is moved from the first position 3a to the second position 3b at the time of a breaking operation of the operating device, and from the second position 3b to the first position 3a at the time of a closing operation of the operating device. An exhaust port 7 in the operating cylinder 2 communicates with the first chamber 2a when the operating piston 3 is disposed near the second position 3b, and with the second chamber 2b when the operating piston 3 is remote from the second position 3b. High-pressure air is introduced into the first chamber 2a at the time of the breaking operation. The operating device also includes an exhaust valve device 4 for discharging the air from the first chamber 2a when the air pressure within the first chamber 2a decreases below a predetermined level. The exhaust valve device 4 includes a valve element 11 having a pressure-receiving portion 11a which receives the air pressure from the first chamber 2a. The pressure-receiving portion 11a is so positioned that it is out of contact with the operating piston 3 when the latter is disposed at the first position 3a.
