この発明はガス絶縁母線に関するもので、特に
ガス絶縁母線の接地方式に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gas insulated bus bar, and more particularly to a grounding system for a gas insulated bus bar.

されている構成である。 To explain the conventional grounding method for gas-insulated busbars,
As shown in Fig. 1, both ends of the tank containing the same-phase current-carrying conductors and insulating gas of the gas insulated buses 1 and 2 are connected to other-phase tanks by conductive bars, that is, shorting bars 3 and 4. The supporting frames 5 and 6 are connected via rising ground wires 7 and 8 to a main ground wire 9 that is part of a ground network buried underground.

あつた。 In such a configuration, when the bus current directions of the gas insulated buses 1 and 2 are in different directions, the gas insulated bus 1
Almost no induced current due to the bus bar current flows through the main grounding wire 9a between and 2, and much of it flows through the shorting bars 3 and 4. However, when the bus current directions are in the same direction, the induced current flowing through the shorting bar on the opposing gas insulated bus side is small, and the rising ground wires 7 and 8 on the opposing gas insulated bus side and the gas insulated bus Most of the current flows through the main grounding wire 9a between them. For this reason, the exposed portion of the grounding wire becomes heated and is dangerous, and there are also drawbacks such as causing the grounding wire to melt.

る。 In order to achieve the above object, this invention collects the grounding wires of gas-insulated bus bars, tanks, etc. of the same phase in one place, and connects them to a part of the grounding network buried in the site where the tank is installed. The present invention provides a gas insulated bus bar which is characterized in that it is connected to the main ground wire buried in parallel with the gas insulated bus bar at one point, and in the center of the tank.
以下に、図示する実施例に基づいてこの発明を
説明する。 The present invention will be explained below based on the illustrated embodiments.

るので説明は省略する。 As shown in Fig. 2, an auxiliary grounding wire 10 is provided in parallel with the gas insulated busbars 1 and 2, and rising grounding wires 7 and 8 are connected to this to ground each tank and frame 5 and 6 of the gas insulated busbar. do. Also, the auxiliary grounding wire 10
are connected to a main grounding wire 9, which is part of a grounding network buried in the site where the tank is installed, at only one location, and through a connecting grounding wire 11 at the center of the tank on the gas-insulated bus bar. Other configurations are in the second
In the figure, members that are the same as those in FIG. 1 are designated by the same reference numerals, so their explanation will be omitted.
そのようにすることにより、第1図の誘導電流

でき、露出接地線の安全性が向上すると共に、過
熱による接地線の溶断が防止できる効果がある。 As described above, according to the present invention, since the current flowing through the ground wire can be reduced, heating of the ground wire can be prevented, the safety of exposed ground wires can be improved, and melting of the ground wire due to overheating can be prevented. There is.
