In FIG. 1, when the pull-out circuit breaker 1 is carried in from the position A in the carry-out state to the carry-in position in the position B or C in the carry-in state, the urging force of the return spring 31 and the stopper 32 cause the state shown in FIG. The pair of shutters 22 that have been closed to close the disconnecting sections 12 and 13 are opened. That is, the roller 2 of the drive lever 25 in FIG.
7 is pushed by the drawer type circuit breaker 1, and one end of the drive lever 25 advances and at the same time the other end moves backward. For this reason, as shown in FIG. 2, the pair of shutters 22 opens together with the driven lever 28 to the opposite disconnection side via the connecting rod 29. Therefore, the drawer type circuit breaker 1 can be carried in.

Therefore, the biasing force of the return spring 31 acts to close the shutter 22 together with the rotary shaft 20 as shown by a virtual line, and the stopper 22 abuts and stops. Therefore, when the drawer type circuit breaker 1 is carried out, the disconnecting section 1
There is no possibility that a person accidentally touches the disconnecting sections 12 and 13 which are the charging sections, because the shutters 22 and 13 block the sections 2 and 13. Further, even if a person leans on the shutter 22 with the shutter 22 closed, the person does not fall into the disconnecting sections 12 and 13 due to the presence of the stopper 32.

される。As can be seen from the above description, according to the switchgear according to the present invention, the shutter opens and closes in conjunction with the loading / unloading operation of the draw-out type circuit breaker. When this happens, the disconnection section is closed by the shutter. Therefore, an electric shock accident caused by a person coming into contact with the disconnecting section when the drawer type circuit breaker is carried out is prevented.
