A gas insulated conduit busbar is constructed by placing a high voltage conductor along with an insulating gas, such as SF 6 gas, within a single grounded metal enclosure. In this gas insulated conduit busbar, an insulating spacer is used to insulate and support the high voltage conductor to the grounded metal container. The insulating spacer includes a Y-shaped integrated insulating spacer that supports the high voltage conductor radially at three points,
There are also post-shaped insulating spacers that are individually made into columnar shapes. The grounding side of these insulating spacers, which faces the grounded metal container, serves as a fixing part that serves to fix the high voltage conductor to the metal container, and also serves as a guide for absorbing thermal expansion and contraction of the metal container and when inserting the conductor. It is equipped with a slide part that can be used to In addition, the fixed part and sliding part on the ground side of the insulating spacer are assembled into a metal molded in the insulator, and electrically connected through the fixed part and sliding part of this metal, so that they are not electrically floating. to prevent the spread of coronavirus.

したものよりコストが高くなる問題がある。 On the other hand, in the gas insulated conduit busbar constructed in this way, the grounding container thereof may be made of steel or aluminum. If the container is made of steel, its inner surface is usually painted to prevent corrosion, but this paint film does not have sufficient electrical conductivity, so the ground side of the insulating spacer becomes electrically floating, causing corona etc. and causing the insulation to deteriorate. There is a risk of it becoming defective. In addition, if the container is made of aluminum, there is no particular problem with painting it for corrosion prevention, but if the voltage class of the conduit bus is high and the current capacity is relatively small, the diameter of the container of the conduit bus may be affected by the electric field. There is a problem that the diameter is relatively large only from the viewpoint of strength, and the cost is higher than that made of steel when the eddy current loss is small.

The present invention will be described below with reference to embodiments shown in FIGS. 1, 2, and 3. First, in Figures 1 and 2, the gas-insulated pipeline busbar of the present invention has a high-voltage conductor 2 inserted into a grounded metal container 1, and the surrounding area is insulated from the ground with an insulating gas such as SF 6 gas. is ensured. The high voltage conductor 2 is insulated and supported on the inner surface of the grounded metal container 1 by an insulating spacer 3 cast integrally therewith. This insulation spacer 3
3 extends in a Y shape in the radial direction from the high voltage conductor 2
It has book supporting arms 4a, 4b, 4c, each with an embedded metal fitting 5 at the end facing the inner surface of the metal container 1.
a, 5b, and 5c are buried. This embedded hardware 5
a, 5b, 5c as shown in FIG.
a, 6b, 6c and contacts 7a, 7b, 7c are provided, and the sphere 9 is further connected via springs 8a, 8b, 8c.
a, 9b, and 9c are provided. That is, at the ground side end of the insulating spacer 3, slide parts 10a, 10b, and 10c, which also serve as fixing parts, are formed by an embedded metal part 5, a shield 6, a contact 7, a spring 8, and a spherical shape 9. Therefore, the main body of the grounded metal container 1 is made of steel material 1a whose material cost is relatively low, and its inner surface is coated with anti-corrosion coating.
The stainless steel material 1b, which does not require anti-corrosion coating, is used for the portions facing b and 10c. And a container made of steel material 1a and stainless steel material 1b
The container made of is integrally connected by welding 11.

おそれがなくなる。 Now, in the gas insulated conduit busbar of the present invention constructed as described above, the high voltage conductor 2 is fixed to the inner surface of the grounded metal container 1 by the sliding portions 10a, 10b, 10c of the insulating spacer 3, and is prevented by vibration. It does not move, and the movement of the high voltage conductor 2 during insertion and placement and due to thermal expansion and contraction can be absorbed by the contact 7 and the slide of the spherical shape 9. In addition, since the contact 7 and the spherical shape 9 slide in contact with the inner surface of the container made of stainless steel material 1b, the embedded hardware 6 is secured with the same ground potential as the metal container 1 via the contact 7, and is coated with anti-corrosion coating. This eliminates the risk of corona generation due to poor energization or deterioration of the performance of the insulating spacer 3 as described above.

Although the drawing shows a single-phase busbar, it may also be applied to a three-phase gas-insulated pipeline busbar. In this case, the insulating spacer 3 is also cast integrally with the three-phase high voltage conductor. Alternatively, post-shaped insulating spacers may be used.

As described above, according to the present invention, the main body of the grounding metal container is made of a steel material with low material cost, and the part facing the grounding side sliding part of the insulating spacer is made of a stainless steel material, thereby reducing the overall manufacturing cost. death,
In addition, since stainless steel materials do not require anti-corrosion coating, the metal fittings embedded in the sliding part of the insulating spacer are maintained at the same potential as the container via the contacts, which prevents the generation of corona due to poor energization and poor insulation. disappears.
