<P>PROBLEM TO BE SOLVED: To solve the problem that a switchgear cannot be reduced in size because the length of a main circuit for the portion of one circuit is long and there are many portions which require assured insulation distance. <P>SOLUTION: The switchgear includes a three-phase buss line 11 in which respective phases are arrayed in vertical direction, a breaker 12 which is arranged parallel to the three-phase bus line 11 and in which respective phases are arrayed in vertical direction so as to face respective phases of the three-phase bus line 11, a primary side connection body 13 which is connected to the phases of the breaker 12 respectively and in which each phase of the breaker 12 is connected to each phase of the three-phase bus line 11, a secondary side connection body 16 which is provided to the phases of the breaker 12 respectively and is configured shorter than the primary side connection body 13, and an external line connection conductor 17 which is arrayed parallel to the three-phase bus line 11 and in which one side is connected to the secondary side connection body 16 arrayed in vertical direction respectively while the other side is connected to an external line cable. <P>COPYRIGHT: (C)2010,JPO&INPIT |
