摘要： A sensor 5 optically detects a colour reaction in a thin film 4 of colour indication material by means of transmitted light and reflected light to thereby detect the absence or presence of an acidic substance or a basic substance. Solid material constituting the thin film is vapour-deposited on a surface of a prism and the thickness of the thin film is in the range 100 ANGSTROM - 600 ANGSTROM . The sensor is applicable to electrical apparatus with gaseous (SF6) insulation, to detect decomposition of the gas as a result of arcing etc.

摘要： PURPOSE:To obtain an abnormality detector for gas in which the number of optical fibers is decreased. CONSTITUTION:The abnormality detector for gas detects acid or basic substances by irradiating a color developing material 4 with light from a light source 6 and detecting the color reaction optically. The abnormality detector comprises an optical fiber 10b connected with one end of the optical detecting section, and a unit 12 connected with the other end of the optical fiber 10b in order to separate the incident light from the reflected light.

摘要： PURPOSE:To sensitively detect deterioration, abnormality, etc., by fixing a coloring matter in an insulating medium, irradiating it with the light from a light source which includes the wavelength band varied coloration, resolving reflected or transmitted light or their composite light into a spectrum through a coloring material and measuring it by an optical sensor. CONSTITUTION:The detecting device is equipped with the ground container 1 of a gas-insulated equipment, the metallic conductor 2 of the gas-insulated equipment, SF6 gas 3, and the coloring material 4. Futher the light source 6 of such construction that the coloring material 4 is irradiated with the light from the light source 6 which has a wavelength band varying by coloration, a device 7 which resolves the reflected or transmitted light or their composite light into the spectrum through the irradiated coloring material 4 with the light from the light source 6, the sensor 8 which detects the spectrum-resolved light, and an arithmetic means 9 which processes the output of the sensor 8 and outputs the intensity of light in wavelength units are provided. Then the coloration is utilized to detect a fine color change sensitively. Consequently, an abnormal coloring part can be searched for.

摘要： PURPOSE:To stably manufacture sensors with good sensitivity in large quantities by providing a solid forming a thin film on the surface of a prism, and setting the film thickness to 100-600 Angstrom . CONSTITUTION:A coloring material is dissolved in an organic solvent, the organic solvent is dried for re-crystallization, then a thin film 11 is formed by vacuum deposition. The thin film 11 of the coloring material can be formed on the surface of a prism 5, and an acidic or basic material is detected with best sensitivity by controlling the thickness of the thin film 11. The optimum value exists for the thickness of the thin film 11 of the coloring material, and the sensitivity for optically detecting the color reaction is improved when the thickness is the optimum value and homogeneous. The thickness 100-600 Angstrom of the thin film 11 of the coloring material is adequate, and the optimum value is about 300-400 Angstrom . When the thin film 11 is formed by vacuum deposition, sensors with good sensitivity can be stably manufactured in large quantities.

摘要： A phase-shifting transformer is disclosed which comprises a six-phase core (31) including six independent magnetic circuits, numbered first through sixth from right to left in the figure. The combined U-, V-, and W-phase windings of the main transformer unit (1) link with the fifth, third, and first magnetic circuits, respectively; on the other hand, the combined a-, b-, and c-phase windings of the series transformer unit (11) link with the sixth, fourth, and second magnetic circuits. The winding directions of the V- and b-phase windings are reversed with respect to those of other phase windings. Thus, the phase angles between the main magnetic fluxes generated in any two adjacent magnetic circuits are equal to 30 degrees. Consequently, the magnitudes of the differential magnetic fluxes passing through the interphase portions (34) between two adjacent magnetic circuits are reduced to about one half of the magnitudes of the main magnetic fluxes, with the result that the cross-sectional area of the interphase portions (34) of the core can be reduced to about one half of that of its main leg portions (33).
