Title: Method for detecting combustible gas in insulating oil
Inventor: MOTOMURA KIYOICHI
IPC: G01N27/00
Filed: 1988-02-15
Abstract: PURPOSE:To increase the detection sensitivity and to make the detection efficient by a simple device by extracting in-oil dissolved gas to a space formed on the surface of sample oil by reducing the pressure in a gas extraction container containing the sample oil, and then extracting the in-oil dissolved gas by bubbling wherein air is blown into the sample oil in the pressure reduced state for abrupt expansion. CONSTITUTION:The sample oil 5 is put in the gas extraction container 1, which is sealed; and its capacity is increased to form the space 7 on the surface of the sample oil 5. At this moment, the pressure-reduced state is entered to generate bubbles of the in-oil dissolved gas and the sample oil 5 bubbles by itself. Thus, the in-oil dissolved gas is extracted speedily. The self-bubbling is stopped and the in-oil dissolved gas proceeds to slow-speed stationary extraction by the diffusion of the gas. Then the air is supplied 15 into the sample oil 5 from the lower part of the container 1 a slight time later to perform the bubbling. The air is blown in the pressure reduced state at the start, so the air expands abruptly and impact operation is carried out for stimulation, thereby increasing the extracting speed of the in-oil dissolved oil. Necessary mixed gas is produced during this period to increase the efficiency of the detecting operation.
