DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a spacer, and its purpose is to realize a spacer that can exhibit equivalent mechanical and electrical characteristics from either side.

In gas-insulated switchgear and the like, spacers are used to insulate and support conductors inserted into adjacent chambers and to partition the chambers in a gas-tight manner.

In FIG. 7 showing a conventional device in FIG. 1, 1 is a spacer whose body 2 is formed into a disk shape from epoxy resin or other solid insulating material. Reference numerals 5n to 3C indicate three-phase through conductors that pass through the main body 2 of the slider, and the through portions protrude to one side to form projecting portions 41 to 4C, and a recessed portion is formed on the back surface thereof.

Here, the conductor penetration part is made to protrude only on one side of the spacer, and mechanically, when there is a difference between the pressure of the insulating fluid applied to the upper surface and the pressure applied to the lower surface in (9), which one is higher? The stress generated in the spacer varies depending on the type of spacer. Therefore, in order for one of them to be able to withstand a higher pressure difference, in other words, the spacer's withstand pressure differs depending on the load from the top surface of the spacer and the load from the bottom surface. This creates constraints. In addition, 5.

6Fi is a gas-filled container held in the spacer 1, and in the example of FIG.
The lines are not symmetrical, and the pressure is applied from the same side in the upper and lower halves of Figure 1 (al).
Since the shape of the pressure-receiving surface of C is also different, the stress will be unbalanced. In order to solve the problem caused by the asymmetry in the radial direction plane, as shown in Fig. 2, the upper half and the lower half are symmetrically arranged One in which individual dummy protrusions 4d are provided is known.

However, even with this configuration, the stress difference when there is a pressure difference on both sides of the spacer 1 cannot be solved. As a natural consequence, such a stress difference causes a difference in the withstand pressure value of the spacer 1 when the upper surface is pressurized and when the lower surface is pressurized. It is necessary to base the spacer on the lower pressure resistance.Furthermore, once the pressure direction is determined, the pressure resistance performance of the spacer 1 cannot be used effectively unless the arrangement is designed so that the specific surface is oriented accordingly. There are performance and placement constraints.

The present invention aims to solve these inconveniences and to propose a spacer having a shape that is effective in alleviating the stress generated by the spacer.

1) Instead of protruding only from one surface, adjacent protruding portions are alternately protruded from both surfaces, and the same number of protruding portions are provided on both surfaces. Moreover, the arrangement of the protruding portions C, , 7t+ is made symmetrical in both planes so that the generation of unbalanced stress is reduced.

There are invaginations Bb on the back side of the two places in d.

8d, and these are arranged alternately on the circumference passing through their centers. In this state, the 90 degree turning deviation d' is exactly the same even when viewed from the bottom, and there is no change in shape between the top and bottom surfaces. Therefore, due to the pressure difference between adjacent compartments, there is no difference in the stress generated in the spacer between when the spacer is pressurized from the top surface and when it is pressurized from the bottom surface.

Although the case where there are four protruding parts in No. 3 B'/l is illustrated, there are six protruding parts 9a to 9 as in No. 41>;I.
A similar effect can be obtained by alternately arranging protruding portions and recessed portions of the folding spacer 20 of f.

In this way, the most favorable effect is achieved in a spacer that has several protruding parts with invaginated parts on the back surface, but even if it has an odd number of protruding parts, six protruding parts are used. 1 out of 5 locations, 2 out of 5 locations, 6 out of 7 locations, etc. 1! If the protrusion is made in the opposite direction so that it is as close to equilibrium as possible, it will be easier than the conventional one in which all the protruding parts face in the same direction, although it may not be the best case where the shape is exactly the same. The difference in stress between internal pressurization and bottom surface pressurization is much smaller than before! It is clear that the device is more preferable than the conventional one.

If we clarify this with respect to Figure 2 (Figure 5 showing the F F' cross section of at), the outer conical surfaces ■ and J of the adjacent protruding parts
K generates tensile stress when pressure is applied from the bottom surface, but this bonding of both sides, Ii! Since the cross-sectional shape of Ii is unique, it causes stress discontinuity and local stress concentration, which is a weak point in terms of pressure resistance fiP.

On the other hand, in the case of the present invention, FIG.
As shown in FIG. 6, which shows the cross section, the adjacent protruding parts face in opposite directions, and the respective conical surfaces, that is, the left (111
The outer conical surface of 1 and the inner conical surface of 1 (right side in the figure) can be joined almost continuously, and no sudden changes in the cross-sectional shape are created, so local stress concentration can be avoided. Therefore it does not create any weak points on the pressure resistant egg.

Furthermore, as a third effect, the present invention can be suitably applied to a method in which the mounting dimensions of conductors to spacers are different (Japanese Patent Application No. 54-148178), which was previously filed by the same applicant. That is,
In the case of a conductor arrangement such as that shown in FIG. An example of a three-phase bulk gas insulated disconnector is shown in Fig. 8. In the figure, 13 is an operating mechanism section, 14a to 140 are insulated operating rods, 15a to 15c are movable contacts, and 1611 to 16C are fixed contacts. It goes without saying that the spacer 30 provided with this dimensional difference l can also be used for other busbar T-junctions, connection parts between gas circuit breakers and busbars, and the like.

By providing the dimensional difference l at the conductor ends of the spacer 30 in this way, the conductor length of the entire switchgear using this spacer 60 can be reasonably shortened, and the protruding and recessed portions of the spacer 30 can be If the dimensional difference can be adjusted to this, the shapes and dimensions of the conductors attached to the spacer 30 can be made the same, contributing to standardization of parts.

As a spacer having a plurality of conductors, there is a known example in which conductors are arranged on a flat plate and a sleeve part 'fr: which is the same on both the upper and lower surfaces around the tatami body is provided. Although the gist of the present invention is that the pressure resistance performance is the same for the upper and lower surfaces, such spacers are similar in that the shortest line of electric force between the conductor and the peripheral flange is the same in terms of electrical insulation performance. Since everything passes through the solid insulating material that makes up the spacer, the insulation performance of the spacer depends entirely on the solid insulating material, and if there is any variation in the performance of the solid insulating material, this will be reflected in the device that uses the entire spacer. This appears as a buffing of the overall insulation.

However, in the case of the present invention, which has a protruding part and has a recessed part on the back side, fluids such as RFr, gas, and insulating oil enter the recessed part, and the shortest distance between the conductor and the flange is A part of the two force lines passes through the fluid, so
Buffs in the performance of the solid material only have a partial effect on the overall insulation performance, and the insulation reliability of the entire device is greatly improved.
