As shown in FIG. 1, a bus connecting device is a pipeline 12 connected and fixed to containers 4 of electric equipment units (for example, gas-sealed switches) adjacent to each other via insulating spacers 4A and 4B. And a container comprising the telescopic pipe 3 and a female type connector (10A) which is enclosed and housed in the container and has one end on the pipe 12 side which is one end of the through conductor 10 of one adjacent electric equipment unit. A bus conductor 2 which is connected by a male-female connection with the interposition of the connecting body 8 and whose other end on the side of the telescopic conduit 3 is connected to one end of the intermediate connecting conductor 19 by a male-female connection with the interposition of the female connecting body 9; It comprises a detachable conductor 18 interposed and connected between the other end of the intermediate connection conductor 19 and the through conductor 5 of the other adjacent electric device unit.

Referring to FIG. 2, the procedure of the connecting operation of the bus connecting device constructed as described above will be described.
0, 5), first, a male connection portion which is one end of the through conductor 10 of one adjacent electric device unit
(10A) and one end (male connecting portion) of the bus conductor 2 are connected by male and female connection via the female connecting member 8, and the male connecting portion which is the other end of the bus conductor 2 and the intermediate connector 19. And the male connection part is connected to the male and female parts via the female connection body 9. Then, a shield body 14A surrounding the bus connecting portion including the bus conductor 2 is installed as necessary.

Next, the container composed of the short pipe 12 and the telescopic pipe 3 is connected and fixed to the container 4 of the electric equipment unit adjacent to each other via the insulating spacer 4B. At this time, when the length of the container 4 is extended, the length of the container 4 becomes equal to the length (interval) between the adjacent electric device units, and When the pipe 3 is contracted, the pipe 12 or the telescopic pipe 3 is selected to have a length (interval) as long as the work for attaching and detaching the detachable conductor 18 remains.

Lastly, while the telescopic conduit 3 is kept in a contracted state, the detachable conductor 18 is interposed and fixed between the intermediate connecting conductor 19 and the through conductor 5 of the other adjacent electric equipment unit.
Then, the telescopic conduit 3 is extended and connected and fixed to the container 4 of the other adjacent electric equipment unit via the insulating spacer 4A, and the connection operation of the busbar connection device is completed. The detachable conductor 18 is selected to have a length corresponding to the interval between adjacent electric device units.

In the above-described embodiment, the container 4 for accommodating the busbar connection portion such as the busbar conductor 2, the intermediate connection conductor 18, and the detachable conductor 18 is constituted by the pipeline 12 and the telescopic pipeline 3. It will be apparent that the object of the present invention can be achieved even if it is constituted only by the conduit 3.
