PURPOSE:To easily detect whether an oiled electric machine is normal or not, by visualizing color tone of a gas reaction paper and detecting a density of flammable gas component. CONSTITUTION:An abnormality monitor consists of a gas chamber 5 separated by a gas separation film 6, a gas reaction paper 8 provided inside the chamber 5, and a window 7 provided to visualized the color tone of reaction paper 8. Hence, flammable gas generated at an oil 9 in a transformer tank 1 is separated by the film 6 and accumulated in the chamber 5. The visualization of color tone of the reaction paper 8 permits the component and density of flammable gas accumulated, and enalbes to identify whether it is normal or not. The identification of visualization facilitates the maintenance, check and operation. The all time monitoring enables the early finding of emergency in the transformer. |
