摘要： PURPOSE:To obtain a high-quality fluorine-contained inert liquid useful as an insulating refrigerant for electric devices, having simply improved dielectric properties of resistivity, dielectric dissipation factor, breakdown voltage, by bringing a fluorine-contained inert liquid into contact with acid clay. CONSTITUTION:A fluorine-contained inert liquid is brought into contact with acid clay in a gaseous phase, or liquid phase, and in an inert gas atmosphere, if necessary, so that it is purified to give the titled high-purity compound. The fluorine-contained inert liquid usable in the purification includes C8F16O, C6H14, C5F12, C7F16, perfluoromethylhexane, perfluoro-1,3-dimethyl-cyclohexane, etc. In an example, granular acid clay is packed into a glass column having about 2cm inner diameter and about 30cm height, the fluorine-contained inert liquid (C8F16O) is made to flow at about 500ml/min flow rate from the top to it, and the liquid is taken out from the bottom of the glass column.

摘要： PROBLEM TO BE SOLVED: To provide a streaming electrification degree measurement device with high measurement sensitiveness and good workability. SOLUTION: A fluorine group insulative liquid 2a in a sample liquid reservoir 1 is passed through an electric charge generating part 13 while being pressurized by means of a gas supplying device 7 so as to be dropped into a Faraday cage main body 15. In this process, a minute electric current flowing between the electric charge generating part 13 and the ground is recorded by a recording meter 20, and from this electric current and a flow rate of the fluorine group insulative liquid 2a flowing through the electric charge generating part 13, an electrification degree is found. In the electric charge generating part 13, a thin disc-shaped metal sintered body formed by sintering a fiber/grain type stainless steel 316 and provided with multiple holes with a hole diameter of 10-0.5 μm approximately is housed. Using the metal sintered body having the minute hole diameter, a contact area with the fluid is increased, while a flow rate for passing through the metal sintered body is increased by pressurization, so that an electric charge generation amount is increased, and measurement sensitiveness can be improved. The metal sintered body requires no drying process before the use, so that workability can be improved.

摘要： PURPOSE:To simplify driving control and to increase durability, by a method wherein a bellows container having many partitioned chambers is enclosed in an external container, the bellows container is expanded and compressed by the pressure change between one partitioned chamber and the external container, and the fluid is sucked or discharged by the remaining partitioned chambers. CONSTITUTION:Bellows container 11 and external container 12 are evacuated by vacuum pump 19, and gas is sent from intake 15 to No.1 partitioned chamber 11a. At this time, bellows container 11 expands, but the maximum amount of expansion is controlled by stopper 22; and when the pressure inside No.1 partitioned chamber 11a becomes atmospheric pressure, electromagnetic valve 17 is closed, and by switching three-directional electromagnetic valve 21, external container 12 is restored to atmospheric pressure. Then, bellows container 11 contracts and the gas to be collected inside No.1 partitioned chamber 11a of bellow container 11 is compressed. Here, when electromagnetic valve 18 is opened, it is possible to send out the gas collected in bellows container 11 from discharge port 16. Since the bellows container is expanded or compressed by the pressure change in No.2 partitioned chamber 11b and external container 12 in this way, drive control is simplified and durability is improved.

摘要： PURPOSE:To improve detection accuracy of discharge abnormality by sealing perfluorocarbon together with SF6 in a container to contain an electric apparatus body. CONSTITUTION:Perfluorocarbon is decomposed due to abnormal discharge inside an apparatus and produces CF4 gas. CF4 gas is an inert gas and reacts with a constituent of the apparatus or is adsorbed and its concentration hardly reduces with time; therefore, it is suitable as an index gas for inner abnormality detection. When SF6 coexists with perfluorocarbon C8F16O, it produces FC4 clearly and is similarly suitable as an index gas.

摘要： PURPOSE:To make it possible to collect gas easily even when the quantity of gas in oil is small, and also to perform operation continuously and rapidly, by providing a gas extractor, gas discharger and infolammable gas detector. CONSTITUTION:Sample oil in transformer 1 is led to oil-collecting metering container 13 by being suched by bellows type gas discharger 19 and supplied from container 13 to waste oil container 14 by overflowing. Next, solenoid valve 15 is opened to supply the sample oil to bubbling tank 15 and then solenoid valve 16 is closed. With solenoid valve 17 opened, air flows into the oil and then flows into bellows type gas discahrger 19 together with dissolved gas in the oil. When the inside of discharger 19 is kept under the atmospheric pressure, solenoid valve 20 is closed and solenoid valve 24 is opened to send gas to be detected to inflammable gas detector 25 for the measurement. Thus, the operation can be performed continuously and even when the quantity of gas in oil is small, the measurement can be taken with accuracy.

摘要： PURPOSE:To simply discriminate the aspect of an abnormality by indicating the following on a graph: whether an abnormality index component in SF6 gas exists or not; and the concentration ratio between abnormality index components. CONSTITUTION:An internal-abnormality diagnosis method is performed in the following manner: analyzed values are indicated on rectangular coordinates wherein the ratio of SF4 which is found from SF6 gas inside a fluorine-based insulating liquid-filled gas-insulated electric apparatus and form a component concentration in a fluorine-based inert insulating liquid to (CF4+1) whose unit is the same as SF4 and which is expressed by an integer and the ratio of CO2 to (CO+1) whose unit is the same as CO2 and which is expressed by an integer are set on the X-axis or the Y-axis; a discharge and an overheat are discriminated from the ratio of SF4 to (CF4+1); and the degree of an overheat or an arc discharge and a particle discharge are discriminated form the ratio of CO2 to (CO+1). Thereby, the aspect of an abnormality can be discriminated simply and quickly.

摘要： PURPOSE:To prevent a gas pressure in an apparatus from being reduced to improve the safety of the apparatus by a method wherein a fluorocarbon material consisting of a liquid fluorinated aromatic compound is used as an insulating and cooling medium. CONSTITUTION:A perfluoromethyldecalin (a methylnaphthalene fluoride), which is constituted of rings less than two rings out of liquid fluorinated aromatic compounds which are a liquid compound obtainable by fluorinating a benzenoid aromatic compound, is used as an insulating and cooling medium 11. Moreover, as the medium 11, a liquid pitch fluoride, which is the liquid fluorinated aromatic compound, may be used. Provided that, the liquid pitch fluoride is set its boiling point at a boiling point of 100 deg.C or higher to 280 deg.C or lower. Thereby, a gas pressure in an apparatus is prevented from being reduced and the high- safety gas insulating electrical apparatus can be obtained.
