<P>PROBLEM TO BE SOLVED: To provide earthing equipment for a switchgear that can easily earth a switchgear even when the height of a connecting portion of a main circuit at the board side is changed because the switchgear is earthed at a different place. <P>SOLUTION: Earthing equipment 101 for a switchgear is comprised of a switch section with a movable electrode and a stationary electrode which is installed on a movable carrying cart 102, a manipulating section for operating the switch section, and a voltage detector 113 connected to either the movable electrode or the stationary electrode via a conductor. The switch section is provided with: an upper conductor 122 connected to either one of the movable electrode and the stationary electrode; a lower conductor 126 connected to the other of the movable electrode and the stationary electrode; an earthing wire 127 for connecting the lower conductor 126 to a terminal used for earthing of the switchgear; and an adaptor conductor 128 that is selectively connected to either a disconnection portion at the bus bar side or a disconnection portion at the cable side of the switchgear and is permitted to be selectively replaced on either upper or lower face of the upper conductor 122. <P>COPYRIGHT: (C)2010,JPO&INPIT |
