摘要： PURPOSE:To apply prescribed references and techniques to execution of an estimating method of a cause of degradation of oil wherein the cause of degradation of a specimen oil is estimated from a plurality of causes of degradation on the basis of the distribution of composition of a gas component contained in the specimen oil. CONSTITUTION:The degree of assurance of the genuineness of some cause of degradation is set beforehand as a function for the composition ratio of each gas component, in regard to each of a plurality of causes of degradation. The composition ratio of the gas component of the specimen oil is multiplied by the degree of assurance corresponding thereto in regard to each of the causes of degradation in a plurality, and the degree of assurance of that cause of degradation is judged to be higher as the product of the multiplication is larger.

摘要： PURPOSE:To achieve a rapid and highly accurate measurement by performing measurement with the polyvinyl alcohol continuous analysis method of a degree of dispersion in a specific range. CONSTITUTION:A carrier containing boron and iodine within a carrier liquid well 1 is sent by a pump 2 and a polyvinyl alcohol sample is poured to this flow from a sample-pouring port 3 using a micro syringe. A sample reacts within a coil-shaped pipe 4 and shows a green and blue color. It is desirable that the coil-shaped pipe 4 should be provided within a constant-temperature bath 5. Then, by measuring the degree of absorption of light with a detector 6, a polyvinyl alcohol content is measured. An accurate measurement can be made when a degree of dispersion D of the sample is equal to or more than 5 and equal to or less than 80. Namely, when the degree of dispersion is equal to or less than 5, a reaction cannot advance sufficiently and color development strength cannot be obtained or the reaction advances while a mixture is not sufficient and a single peak cannot be obtained. On the other hand, when the degree of dispersion is equal to or more than 80, dilution of the sample advances excessively and a sufficient color development sensitivity cannot be obtained.

摘要： PURPOSE:To conduct the test highly accurately by a few persons in a short time by heating a container so that a distilled component flows at a flow rate so that the component is not deposited, and keeping the temperature of an outlet port at a constant temperature so that the distilled component is not evaporated at the outlet port of a branch pipe. CONSTITUTION:An applying voltage for a hot wire 19 of an electric heater 16 is controlled with a data processing control part 34 in response to the measuring signal of a weight measuring means 26. The distilled component of a sample 14 is made to flow in a branch pipe 24 at a flow rate so that the component is not deposited in the branch pipe 24. For this purpose, a flask 15 is heated at a large quantity of heat per unit time. Thus the crystallization of the distilled component in the branch pipe 24 and the clogging in the pipe are prevented. The voltage which is applied on the hot wire 19 is determined so that the temperature at an outlet port 24b1 of the branch pipe 24 is higher than the depositing temperature of the distilled component and less than the boiling point of the component. Thus, the distilled component is not evaporated at the outlet port 24b1, and the measuring accuracy is improved.

摘要： PURPOSE:To reduce a testing time while measuring combustion time accurately, by a method wherein an insulating oil impregnated by a base material is ignited to generate a flame and the ignition flame light is detected separately passing through two light guide through holes arranged at a specified interval. CONSTITUTION:A plate 23 is arranged in parallel with a horizontal shift portion of a horizontally moving tape 12. Through holes 24 and 25 are formed in the plate 23 piercing it widthwise at a specified interval. Photodetectors such as photodiodes 26 and 27 are set at light outlets of the through holes. The through holes 24 and 25 are expanded in diameter near an incident sector. Outputs from the photodiodes 26 and 27 are inputted into a time counter 28 through a photo amplifier PA and time is measured to the passage of light of ignition flame through the through hole 27 after the passage thereof through the through hole 26.

摘要： PURPOSE:To perform measurement and monitoring continuously by cooling oil to be measured and making the oil turbid in white owing to water in oil, and then detecting the quantity of transmitted light. CONSTITUTION:When the oil to be measured is cooled by a cooling part 4 provided to the by-pass 3 of oil-charged equipment 2, etc., the water contained in it is deposited to make the insulating oil turbid in white. This cooling temperature is monitored by a temperature detecting means 8. Light emitted by a light emission part 5a is made incident on a light reception part 5b, whose light reception quantity is transmitted to a measurement part 7 through an optical fiber. The measurement part 7 calculates the in-oil water according to the relational expression between the quantity of light transmission and in-oil water from the quantity of photodetection after correction and temperature data inputted from the temperature detecting means 8.

摘要： PURPOSE:To permit the reuse of an eluate contg. solute by adding a non-polar solvent to the eluate to extract the solute then separating the non-polar solvent and eluate and pouring the solute contg. no solute again into the column. CONSTITUTION:The column chromatography elutes 1 or >=2 kinds of polar solvents, for example, water, methanol or the solvents added with the non-polar solvent, for example, n-pentane to the range of a satd. quantity by using a column for chromatography packed therein with the packing material prepd. by chemically binding, for example, an alkyl group to a silica gel as the hydrophobic packing material. The non-polar solvent is added to the eluate contg. the solute flowing out of the lower part of the column used in such column chromatography so as to contact therewith, by which the solute is transferred and extracted to the non-polar solvent; thereafter, the non-polar solvent and the elute are separated and the eluate contg. no solute is again poured into the upper part of the column to eluate the solute in the column. The eluate is thereby made reusable without making the operation for distillation, concentration, etc.

摘要： PURPOSE:To enable repair and renewal of electrical apparatus, etc. with high reliability by detecting the degree of thermal deterioration in the process of progression of continuous deterioration from the change in the IR absorption spectrum of an insulating material by IR spectrochemical analysis. CONSTITUTION:An epoxy resin is used for a sample and is deteriorated in a thermostatic chamber. The change in the IR absorption spectrum thereof is measured. The absorbancy ratio of 825cm changing with progression of the deterioration is determined with 1,610cm absorbance as a reference. Activation energy DELTAE is determined by other method and a conversion time theta is calculated. Here (t) denotes the time for deterioration and T the absolute temp. for deterioration. There is a good correlation between the time theta and the absorbancy ratio and if the time theta is equal, the change in the chemical structural quantity owing to thermal deterioration is equal as well. An insulating coil of an electrical apparatus consisting of the same material as the material of the sample is worked for required time and thereafter the insulator is sampled and the absorbancy ratio at 825cm is determined from the absorption spectrum, by which the time theta is obtd. and the remaining life of the insulating coil is detected. This method is applicable to an enamel wire film, coil impregnating agent and film material as well.
