<p>PURPOSE:To prevent irregularity of on/off operation of a disconnecting switch for each phase and unevenness as well as shortage of engaging of a contact piece by transmitting driving force from a plurality of drive links to an operating shaft arranged in parallel to the arrangement direction of a plurality of disconnecting switches. CONSTITUTION:Drive links 6a, 6b are arranged nearly symmetrically to an arrangement central part of three disconnecting switches 1a, 1b, 1c, for example, corresponding to three-phase DC, between the disconnecting switches 1a, 1b and between those 1b, 1c respectively. Accordingly, rotation force of output shafts 5a, 5b of a drive device 4 is nearly uniformly transmitted to a disconnecting switch operating shaft 3 so that torsion of the operating shaft 3 is extremely small. Consequently, drive force of the drive device 4 is efficiently transmitted to movable parts 10a, 10b, 10c of the respective disconnecting switches 1a, 1b, 1c so as to prevent irregularity of on/off operation thereof and unevenness as well as shortage of engaging of a contact piece.</p> |
