More specifically, the method involves filling an insulating gas other than air into a closed container to insulate a high voltage section that is insulated and supported within the container.
絶縁性気体の監視手段を備えたガス絶縁電気機器に関す
るものである。The present invention relates to gas-insulated electrical equipment equipped with insulating gas monitoring means.

す圧力と当該ガス絶縁電気機器のガス圧力とを比較する
方式九より、ガス絶縁電気機器の８Ｆ４ガス量を監視し
ていた。Conventionally, the 8F gas volume of gas-insulated electrical equipment filled with a strong gas of about 3 to 6 atmospheres, such as 8FA gas (hereinafter referred to as 8Fa gas), was automatically determined by measuring the pressure and temperature of the gas. The so-called temperature-compensated pressure relay, which is synthesized by
Alternatively, the amount of 8F4 gas in gas-insulated electrical equipment was monitored using method 9, which compared the pressure of a small container containing a predetermined amount of standard gas with the gas pressure of the gas-insulated electrical equipment.
他方、近年、大気圧近傍の８７４ガスで絶縁するガス絶
縁電気機器が多くみられるようになったが。On the other hand, in recent years, many gas-insulated electrical devices have been seen that are insulated with 874 gas at near atmospheric pressure.
ＳＰ＆ガス量監視装置は依然としてガス密度を把握する
ための一要素である圧力を利用するものであったので、
温度変化範囲内で８ＦＡガス量監視装置が作動するガス
圧力を保持する必要があると共Ｋ。Since SP & gas amount monitoring devices still utilize pressure, which is one element for understanding gas density,
It is necessary to maintain the gas pressure at which the 8FA gas amount monitoring device operates within the temperature change range.
高精度の圧力継電器を要するという問題があった。There was a problem in that a high precision pressure relay was required.
この発明は、以上の点に着目してなされたものであり、
絶縁性能が８ＦＡガスの純度に依存する事実に鑑み、８
７４ガス成分監視手段を備えたガス絶縁電気機器を提供
することを目的とするものである。This invention was made focusing on the above points,
Considering the fact that insulation performance depends on the purity of 8FA gas,
An object of the present invention is to provide a gas-insulated electric device equipped with a 74 gas component monitoring means.

比較的上部に／個または複数個設置される。The present invention will be explained below with reference to the embodiments of the pressure water pump shown in FIGS. A connection end q between the voltage section ko and an external device is provided in the airtight container.
The airtight container is filled with 8F and gas G at about atmospheric pressure. Reference numeral 3 denotes a gas component monitoring device such as an SF, a gas purity measuring device, or an oxygen concentration measuring device, and one or more gas component monitoring devices are installed relatively above the closed container 1.
いま、密閉容器／に微細な気密欠陥があると。Now, there is a minute airtight defect in the airtight container.
ＳＦ ４ガスＧが密閉容器／外へ漏れるばかりでなく。SF 4 Gas G not only leaks out of the closed container/outside.

ＦＡガスの絶縁性能は。Air enters the sealed container l from the outside. This air entering from the outside is diffused inside the sealed container l, and 8? = Air components in the gas, such as oxygen, increase. Therefore, if the gas component monitoring device 3 is an oxygen concentration measuring device, it is possible to monitor the purity of SF and gas G in the closed container 1. S
What is the insulation performance of FA gas?
１０％程変の空気が混入しても僅かしか低下しないので
、実用的には１〜コラの酸素濃度が検出できればよいの
で、汎用の酸素濃度測定装置で十分対処できる。Even if about 10% of air is mixed in, there is only a slight drop, so in practice it is sufficient to detect an oxygen concentration of 1 to 1,000 ml, so a general-purpose oxygen concentration measuring device can suffice.
この発明によれば、運転時の温度範囲において密閉容器
内が負圧とならないようにするための高いガス圧を充填
する必要がなくなり、平均的な温度で大気圧となるよう
に絶縁性ガスを充填すれば足りるので、密閉容器が安価
となる。According to this invention, it is no longer necessary to fill the closed container with high gas pressure to prevent negative pressure within the temperature range during operation, and instead fill the airtight container with insulating gas to maintain atmospheric pressure at average temperature. Since it only needs to be filled, airtight containers are cheaper.
