置などが知られている。2. Description of the Related Art In general, a gas-insulated switchgear is a device which is constructed by supporting a conductor in a container filled with an insulating gas so as to be insulated from the container, thereby enabling a three-dimensional arrangement. Since it has a good space property, it has become widespread in recent years. As one type of this gas insulated switchgear, a phase-separated type gas insulated switchgear has been conventionally known. A phase-separated type gas-insulated switchgear is a switchgear that is configured by connecting a busbar, etc., to a circuit breaker via a gas-insulated conductor that includes circuit means such as a disconnector, and configures this switchgear individually for each phase. It is a device provided. As a conventional example of this type of phase-separated gas-insulated switchgear, the device described in JP-A-62-110407 is known.

されている。Here, the construction of the phase-separated gas insulated switchgear disclosed in Japanese Patent Laid-Open No. 62-110407 will be specifically described with reference to the front view of FIG. That is, the disconnecting portions 2A and 2B are housed in the substantially L-shaped containers 150 and 160, and the main busbars 1A and 1B are connected to the disconnecting portions 2A and 2B.

互に干渉することがない。In the phase-separated type gas-insulated switchgear described above, it is required that the phase-separated main buses do not interfere with each other. In order to satisfy this requirement, in the device shown in FIG. 4, one phase of the main buses 1A and 1B, for example, V phase, is coaxial with the disconnecting portions 2A and 2B of the substantially L-shaped containers 150 and 160 and other U phases. , W-phase are separated from each other on the left and right sides of the V-phase so that the three phases are located at the vertices of an equilateral triangle. In the above-described conventional example, the positions of the main buses 1A and 1B can be distributed in this manner, and the main buses 1A and 1B do not interfere with each other.

することが望ましい。By the way, generally, the gas-insulated switchgear is assembled and tested in a factory and shipped before the state shown in FIG. The unit assembled up to the state of being shipped is usually called a factory shipping unit. This factory shipping unit is shipped according to the switchgear of the substation or power plant, and the switchgear is installed by connecting the gas-insulated main buses of the factory shipping units adjacent to each other at the substation or power plant. Composed. Therefore, in order to facilitate the work of connecting the main buses at the site, it is desirable to set the dimensions between the main buses in the factory shipping unit to be the same.

The linear portion of 160 is bent and connected by about 60 degrees. At this time, the containers 150 and 160
As a connecting portion for connecting the U-phase and W-phase main buses 1A and 1B, a branch connecting portion having a bent portion of about 60 degrees in the middle is used. The connection work using such a branch connection part is difficult, and the work efficiency when connecting the main busbars of a factory shipment unit is reduced, and the work time was increased.

的な利点を低減させていた。Further, since a slight manufacturing tolerance in the branch connection portion leads to a deviation in the dimension between the main buses, it is necessary to manufacture the branch connection portion with a precise dimension. Therefore, the manufacturing cost of the branch connection portion is high, which is economically disadvantageous. Further, since the branch connection portion is spread to the left and right, the exclusive space of the entire bus bar connection portion is increased. Such an increase in space brings about the problem of making the device larger,
It has reduced the basic advantage of the gas-insulated switchgear, which has a high space property.

きた。As described above, according to the gas-insulated switchgear according to the first aspect of the invention, the first gas-insulated conductor having the busbar connecting portion at the lower end of the container in which the circuit means is built-in is cut off. By attaching a second gas insulated conductor having a busbar connecting portion near the container and a third gas insulated conductor having a busbar connecting portion at a distance from the circuit breaker, and connecting a busbar of each phase to each of the connecting portions, Bus lines can be distributed without using a bent branch connecting part, and the manufacturing cost can be reduced as much as the bent branch connecting part is unnecessary.
In addition, since the space occupied by the branch connection portion is reduced, it is possible to contribute to downsizing of the device. Moreover, in the gas-insulated switchgear according to claim 1, when a container for housing the gas-insulated conductor and a container for housing the busbar are manufactured, all of these containers are on the same axis or perpendicular to the axis of the container for housing the circuit means. Since it can have a branch connection port, it is not only easy to manufacture, but also it is easy to set the dimension between the main busbars of each phase to the same dimension, which reduces the work time to connect the busbars of the factory shipping unit. I was able to shorten it.
