きるようにしてある。 FS 6 gas is sealed in a sealed container for each transformer such as a gas insulated switchgear, disconnector, busbar, etc., and these are combined into a unit, reducing installation space, safety, installation time, etc. There are some useful points,
Many are currently in use. On the other hand, in order to connect the closed containers of each unit, the following must be done. That is, as shown in FIG. 1, conventionally, in order to connect a unit with a conductor 2 in a closed container 1 and a unit with a conductor 4 in another closed container 3, a unit is installed at the ends of the closed containers 1 and 3, respectively. Flanges 1a, 3a are formed, and both flanges 1a, 3
The stud 5 is penetrated through the stud 5 in a, and the nut 6 can be fastened thereto, and an insulating spacer 7 for insulating and supporting the conductor 4 from the airtight container 3 between the flanges 1a and 3a also penetrates through the stud 5. I have made it possible.

ない欠点があつた。 In such a structure, in order to fasten the stud 5 and the nut 6, first, connect the connecting conductor 8 which is fixed through the center of the insulating spacer 7.
Insert and fix the ends of the conductors 2 and 4, respectively, and then attach the insulating spacer 7 to the flange 1a of the sealed container 1.
A stud 5 is inserted through and fixed to the flange 3a of the closed container 3, and a nut 6 is screwed into the stud 5 to connect the closed containers 1 and 3 to each other. At this time, the connection of conductors 2 and 4 becomes a blind operation inside the sealed container.
If you cannot match each core, there is a risk of damaging or breaking the conductor. Therefore, in order to carry out this work more safely and reliably in terms of quality, guide bolts 10 have been conventionally used on the flanges 1a and 3a of the closed containers 1 and 3 in addition to the studs 5 mentioned above, as shown in FIG. This is what I did. In such a structure, when connecting the unit in which the sealed container 1 and the conductor 2 are assembled to the unit in which the sealed container 3, the insulating spacer 7, and the conductors 8 and 4 are assembled, first the stud screwed into the insulating spacer 7 is connected. Replace only two guide bolts 10 of 6. First, the guide bolt 10 and the flange 1 of the sealed container 1 are connected.
The tightening hole a is then tightened, followed by the conductors 8 and 4, followed by the sealed container 1 and the insulating spacer 7. After joining, the stud 6 is tightened using a nut (not shown). Thereafter, the guide bolt 10 is replaced with the stud 6 and tightened to complete the fastening. However, in the case of the configuration shown in FIG. 2, the case 11 of the through-type current transformer may be installed on the outer periphery of the closed container 3 as shown in FIG. 3, and in this case, the guide bolt 10 and There was a drawback that the guide bolt 10 could not be used because the stud 10 could not be tightened after being replaced.

る。 This idea was developed in consideration of the above points, and it makes it easy to attach and detach the guide bolts used during assembly, and also in cases where the outer space of the container to be fastened is used and the container connecting stud cannot be tightened. An object of the present invention is to provide a container connecting device in which a guide bolt can be easily attached.

The fastening is performed by a stud 21 and a guide bolt stud 23 screwed into a threaded metal fitting 7a cast into a predetermined position of the insulating spacer 7. This stud 23 has a screw diameter that is screwed into the flange portion of the insulating spacer 7 and the flange portion 1 of the containers 1 and 3 in order to attach the guide bolt 22 when connecting each unit.
The diameters of the screws entering a and 3a are different. FIG. 5 is an enlarged view of the stud 23.

The stud 21 is guided through the stud hole in the flange 1a of the container 1 so that the conductors 2 and 8 are smoothly connected, and then the stud 21 is inserted into the stud hole in the flange 1a of the container 1. After joining, the guide bolt 22 is removed and used together with the stud 21 for fastening.

旨を変更しない範囲で種々変形して実施できる。 Note that this invention is not limited to the above-mentioned embodiments, but can be modified and implemented as follows. That is, as shown in FIG. 6, the thread diameter of the part of the stud 23A that is screwed into the screw fitting 7a cast into the flange of the insulating spacer 7 and the part that enters the flange 3a of the container 3 is the same, so that each unit can be connected. Even if the diameter of the screw that enters the flange portion 1a of the container 1 to be tightened later is different, the same effect as in the above-mentioned embodiment can be obtained. Further, the mounting portion of the stud 23A may be such that a ring 24 as shown in FIG. 7 is interposed between the containers 1 and 3, and a screw hole into which the stud 23 is screwed is formed in the ring 24. In addition, various modifications can be made without changing the gist of the invention.
