Abstract

PURPOSE:To discharge air efficiently from a cubicle in a short time using less amount of insulating gas, by introducing said insulating gas through the valve on the lower part of said cubicle and discharging air from the valve on the inclined top, and reintroducing the gas after a certain time. CONSTITUTION:In a substitution process in which an insulating gas 3, such as SF6, is introduced in a gas cubicle 1 through a stop valve 2, and the air is discharged at a stop valve 4 on an inclined top 1a, the gas 3 is mixed with air and unsubstituted air remains. After being left for a certain time, the gas 3 with a greater sp.gr. moves downward and the air with a smaller sp.gr. moves upward. When substitution work is resumed at this point, the remaining air is discharged promptly along the angle of inclination 1a, through the valve 4. Thus, the density of gas 3 can be increased in a short time thereby reducing the required gas quantity.

。Gas-insulated switchgear is usually filled with an insulating gas such as 8F gas to maintain insulation of live parts. In this case, the higher the purity of the insulating gas, the better the insulation. However, if a gas cubicle such as a closed switchboard housing a gas insulated switchgear interrupter, an instrument transformer, or an instrument phase changer is filled with insulating gas and vacuumed, the structure of the unit will withstand atmospheric pressure. Therefore, air and sF using windsocks are generally used.
.

ガスとを置換するガス充填方法が行なわれている。A gas filling method is used to replace the gas.

であって、！！１図のようにガスキユービクル（１）の
下部の止弁（２）から絶縁性ガス例えばｓｙ。That is, 8F is a method that takes advantage of the fact that the specific gravity of gas is 5.0 when air is 1.0, which is larger than air. ! As shown in Figure 1, an insulating gas such as SY is supplied from the stop valve (2) at the bottom of the gas cubicle (1).

不紅済である欠点があった。The method would be to fill the gas (3), exhaust the air and Shp gas from the upper stop valve (4), and replace the air in the gas cubicle (11) with 8-ton gas [Problems with the background art] ] However, in order to increase the 8F gas concentration after replacement, it is necessary to supply gas to 8F from the stop valve (2) at the bottom for a long period of time, and then exhaust air and 8F gas from the stop valve (4) at the top. However, it had the drawback of requiring a large amount of gas and being inconvenient.

〔発明の目的〕[Purpose of the invention]

本発明は上記欠点に鑑みなされたもので、絶縁性ガスの

ガス充填方法を提供することを目的とする。The present invention was made in view of the above drawbacks, and an object of the present invention is to provide a method for filling a gas cubicle with gas, which reduces the amount of insulating gas used and increases the gas concentration.

方法である。In other words, insulating gas is injected from the stop valve at the bottom of the gas cubicle, the air is exhausted from the stop valve provided at the top of the slanted upper part, and the air is left for a predetermined period of time, then insulating gas is injected again. This is a method in which a large insulating gas is moved under air with a low specific gravity and then replaced again to increase the gas concentration.

〔発明０＊施例〕 以下本発明をＷＪ向に示す一実施例について説明する。[Invention 0*Example] An embodiment of the present invention directed toward WJ will be described below.

The gas is injected into the tank, the upper O stop valve (4) is opened, and the replacement work with 8F6 gas (3) is performed for a certain period of time. Next, as a second step, the replacement work is performed again after leaving it for a predetermined period of time.

２回に限定せず３回以上置換作業を実施してもよい。Next, the effect will be explained. In the replacement work in the first step, air is mixed into the 8F gas, and air that is not replaced remains. Next, in the second step, when left for a predetermined period of time, the SF gas with a high specific gravity flows below the gas cubicle (1).
Air with lower specific gravity moves upward. Then, the replacement work is performed again. Then, the air accumulated upward is quickly discharged from the stop valve (2) along the upper slope (08). Note that the replacement operation is not limited to two times, but may be performed three or more times.
