Zusammenfassung: | PURPOSE:To make it possible to detect the gas at a plurality of the parts to be detected, by connecting one gas detecting part and a plurality of the parts to be detected by a carrier gas pipe wherein directional control valves which can connect or cut said parts, and contacting the gas in each part to be checked to a gas detecting body. CONSTITUTION:A power source in a gas detector 9 is turned ON, and the gas detecting body 10 and a carrier gas supply device 13 are operated. Then, the gas which is separated from oil by gas separating devices 4a-4c of oil filled equipment 1a-1c is stored in gas storing containers 5a-5c. The four way directional control valve 6c is changed so that the carrier gas flow path is the path shown by a dotted line. Then the gas in the container 5c is sent to the gas detecting body 10 together with the carrier gas, the gas is contacted with the gas detecting body 10, and the output corresponding to the gas concentration to be detected is obtained. After the measurement of the gas, the valve 6c is changed to the flow path shown by the solid line. Such an operation is sequentially performed for the four way directional control valves 6b and 6a, and the gas concentrations of the oil filled equipment 1a, 1b, and 1c are measured. |
