<p><P>PROBLEM TO BE SOLVED: To provide a bus supporting device in which a height or depth dimension of a housing is made compact and improvement in the strength of the housing which corresponds to electromagnetic force between buses due to three-phase short-circuit current of the bus is not necessary to be taken into account, and to provide a switchgear that uses the device. <P>SOLUTION: The bus support device 1 is constituted to arrange and support the buses 2 of three-phases at the positions of apexes of a triangle. The device is constituted of a support member 3, formed of an insulator such as a molding of epoxy resin. Thus, the respective phases of the buses 2 are linearly supported by the support member 3 formed of the insulator. The support member 3 is constituted of a member, having strength which withstands the strength of the electromagnetic force acting on the mutual buses 2 by the three-phase short-circuit current. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
