この発明はガス絶縁母線に関するもので、特にガス絶縁
母線の接地方弐罠関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gas insulated bus bar, and more particularly to a grounding trap for a gas insulated bus bar.

ワに接続されている構成である。To explain the conventional grounding method for a gas insulated bus, as shown in Fig. 1, the gas insulated bus has conductors of the same phase and a tank containing insulating gas at both ends with conductive bars or shorting bars 3. , 4I is connected to the other phase tank, and the frame 3.6 supporting the tank stands up and is grounded m7. g
It is connected to the main ground wire, which is part of the ground network buried underground, through the ground wire.

め、接地線が加熱し露出している部分では危険であり、
又接地線の溶断の原因となる等の欠点があった。In such a configuration, when the bus current directions of gas insulated bus bars /1 and 2 are in different directions, almost no induced current due to the bus current flows in the main ground wire 9a between gas insulated bus bars /1 and 2. Most of the current flows through the shorting bars 3 and 4I. However, when the bus current directions are the same, the induced current flowing through the shorting bar on the opposing gas insulated bus side is small, and the induced current flows through the rising ground wire q on the opposing gas insulated bus side and the gas insulated bus bar. The main ground wire between? Most of it flows into a. For this reason, exposed parts of the ground wire are dangerous as they heat up.
Also, there were drawbacks such as causing the grounding wire to melt.

のである。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.

説明は省略する。The present invention will be explained below based on the embodiment shown in Figure 1.8 As shown in Figure 1, an auxiliary grounding wire 10 is provided in parallel with the gas insulated busbars, and each tank and mount of the gas insulated busbars are Yo, connect the rising ground @71g to ground 6. In addition, the auxiliary grounding wire/θ is connected to the main grounding wire, which is part of the grounding network buried on the site where the tank is installed, at only one location, and the contact grounding wire/θ is located at the center of the tank on the gas-insulated bus bar. Connect via /. The other components are shown in FIG. 1, and the same members as in FIG.
