Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an adsorbent container in a gas insulator or disconnector.

1 to 4 show the conventional structure of this type of adsorbent container. In Figures 1 and 2,
The adsorbent containers 1 and 2 are attached inside the inspection lids 4 and 5 of the grounded tank 3, respectively. Therefore, in these cases, it is necessary to have a lid that can be removed from the grounded tank 3, and it is also necessary to perform processing to attach the adsorbent container to the back side of the lid.

In addition, in FIGS. 3 and 4, adsorbents 6, 7
Both of these are stored in a space inside the grounded tank 3, but since the area where the adsorbent comes into contact with the polluted gas is small, a large adsorption effect cannot be expected.

The present invention is directed to an adsorbent container that eliminates these drawbacks, provides a large adsorption effect on the adsorbent, and can be manufactured at low cost. Hereinafter, the present invention will be described with reference to embodiments.

FIG. 5 shows a sectional view of a gas insulating shield and breaker to which the present invention is applied, in which 11 is a grounding tank, 12 is a gas butting, 13 is a fixed side insulating tube, 14 is a movable side insulating tube, and 15 is a fixed side contactor. , 16 is a movable side contact, 17 is a fixed side lid of the grounding tank, 18 is also a movable side lid, and 19 is a crankcase. FIG. 6 is a sectional view showing the adsorbent container 20 of the present invention attached to the fixed side lid 17 of the gas chamber disconnector, and FIG. 7 is a front view of the adsorbent container 20 taken along arrow A-A'. Furthermore, a side sectional view of the adsorbent container 20 is shown in FIG. In order to show the mounting state of the adsorbent container 20, the grounded tank 11, the flange 11a, and the fixed side insulating cylinder 13 are shown in chain lines in FIG. 26 is indicated by the center line. Further, in FIG. 8, the insulating cylinder holding member 23 is shown by a chain line, and the mounting bolt 24a is shown by a through hole 24, respectively.

As is clear from FIG. 8, the adsorbent container 20 is made by integrally joining an inner container 21 and an outer container 22, which are formed by drawing or other means from a metal plate with a large number of small holes 21a, by spot welding or the like. Further, as shown in FIG. 6, the adsorbent container 20 is inserted between the fixed side lid 17 and the insulating cylinder holding fitting 23, and is fixed with a mounting bolt 24a.

That is, the inner container 21 is drawn into a bent shape as shown in the figure to match the outer periphery of the annular insulating cylinder holding fitting 23, and is formed into a dish shape with the center portion removed, and the contaminated gas is distributed near the outer periphery. A large number of small holes 21a are provided for this purpose. Also, outer container 2
2 is provided with a positioning/adsorbent filling port 25, and the outer periphery is drawn to match the inner diameter of the ground tank 3, and is similarly formed into a tray shape with the center portion omitted.

Next, as described above, the inner container 21 and the outer container 22 are integrally connected, and the adsorbent container 20 is provided with the doughnut-shaped adsorbent storage section 20a around the periphery.
is configured.

The adsorbent container 20 manufactured in this way is positioned and the adsorbent filling port 25 is connected to the hole 1 of the fixed side lid 17.
7a, and attach it to the fixed side lid 17 together with the fixed side insulating cylinder 13 and the insulating cylinder holding fitting 23 using bolts 24a. In this case, the insulating cylinder holding fitting 23
By providing a counterbore in the mounting bolt 24a so that the head of the mounting bolt 24a is sunk into the counterbore, it is possible to prevent the ground potential metal from protruding. After various parts are attached to the fixed side lid 17 in this manner, they are attached and fixed to the flange 11a of the grounded tank using bolts and nuts 26.

A threaded and airtight blind plug 27 is provided in advance in the hole 17a of the fixed side lid, and after the assembly of the breaker is completed, the blind plug 27 is removed and the adsorbent 28 is inserted into the hole 17a.
Fill the internal adsorbent storage section 20a through the adsorbent container positioning and adsorbent filling port 25, and then close the blind stopper 2 again.
7 and seal.

As described above, in the present invention, the adsorbent container is disposed in the gap between the outer periphery of the insulating cylinder holding fitting 23 and the inner periphery of the grounded tank 11. Therefore, the area in which the adsorbent contacts the internal pollutant gas is extremely wide, and a large adsorption effect can be obtained.

Further, since the adsorbent container 20 is inserted and attached between the insulating cylinder holding fitting 23 and the fixed side lid 17, no parts or labor are required for attachment. In other words, there is no need for machining such as creating bolt holes in the fixed side lid as in the conventional structure, and there is a big advantage in that it requires less labor and time than the conventional case of attaching the adsorbent container separately. .

As explained above, according to the present invention, it is possible to obtain an adsorbent container that has a large adsorption effect and does not require extra labor or time for installation.
