<p>PURPOSE:To simplify a driving force transmission system to a linking mechanism, improve safety, and also reduce the dimension in an arranging direction of a switchgear main body in an switchgear having a Scott-Russell type linking mechanism. CONSTITUTION:Mechanism boxes 2 containing linking mechanisms for performing the switching action of movable and fixed contacts are arranged in the direction orthogonal to the arranging direction of a switchgear main body 1, and each of driving rotary shafts 20, 21, and 22, provided among the adjoining linking mechanisms, are linked each other, via the linking mechanisms in the mechanism boxes 2, to form one shaft coaxially, and also to be linked to the linking mechanisms. Each of the driving rotary shafts is turned by an operation device 3 to perform the switching action. Consequently since only driving rotary shafts exist each between the switchgear main bodies, a driving mechanism is simplified while improving safety and reducing the dimension among the switchgear main bodies.</p> |
