Abstract
An operating device for effecting opening and closing operation of a vacuum interrupter with an electromagnet incorporated therein comprises a supporting resin block (4) for supporting a vacuum interrupter, a first pair of poles (47a) and a second pair of poles (47b), both extending along the outer circumferential surface of the supporting resin block (4), the length of the first pair being longer than that of the second pair. The operating device further comprises a mounting plate (49) of magnetic material directly connected to the first pair and connected to the second pair through connecting rod means, and an electromagnet (52, 56) fastened to the mounting plate (49), supported by the first and second pairs and connecting rod means (57). Thus, the supporting arrangement for supporting a vacuum interrupter not only serves as a mechanically supporting member, but also does a magnetic path defining member.
