摘要

PURPOSE:To collect oil for analysis with high accuracy in analyzing the concn. of the gas dissolved in the oil within a tank in order to detect the deterioration state of oil-immersed electric machinery. CONSTITUTION:The pipe-shaped oil collecting needle 11 piercing through a tank 1 having oil 8 received therein and having an acute part 12 provided to the tip thereof is attached to the tank 1 so as to protrude to the outside and the tip part of the oil collecting needle 11 is thrust through an oil collecting container 21 whose inner pressure is set to atmospheric pressure or less and the oil 8 in the tank 1 is allowed to flow in the oil collecting container 21 to collect the oil for analysis.
