<p><P>PROBLEM TO BE SOLVED: To solve the problem that standardization of components and cost reduction are difficult because connecting conductors for connecting a three-phase bus bar disposed in a bus bar container to a circuit breaker are different in structure such as the length. <P>SOLUTION: In a switchgear, a first connection 18 is disposed in a second phase bus bar 6b at a position crossing an axial direction of a center-side circuit breaker device 11 corresponding to the center-side second phase bus bar 6b, and a first connecting conductor 19 in which a horizontal distance from the center point of the first connection 18 to the center point of a connecting terminal 15 of the circuit breaker device 11 is a pitch b is disposed along the axial direction of the circuit breaker device 11. A second connecting conductor 21 having the same shape as that of the first connecting conductor 19 and the pitch b same as the pitch b of the first connecting conductor 19 is connected to the connecting terminal 15 of a circuit breaker device 12 and a second connection 20 provided on a third phase bus bar 6c at a position of the same pitch b from the connecting terminal 15. The third connection 22 provided on the first phase bus bar 6a is connected to the connecting terminal 15 of the circuit breaker device 10 via the third connecting conductor 23. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
