Oil in gas analyzer, oil in gas analysis system equipped with the same, and method for analyzing gas in oil carried out using an oil gas analyzer

摘要

To miniaturize and simplify the device configuration of an oil gas analyzer.SOLUTION: A gas extraction chamber 110 extracts gas from an insulating oil therein. A gas detector 110 measures a concentration of each component of the gas. A bag-like member 130 is disposed in the gas extraction chamber 110 and is inflated by putting fluid in and out. The gas is extracted from the insulating oil in the gas extraction chamber 110 by shrinking of the bag-like member 130. The gas is sent from the gas extraction chamber 110 to the gas detector 120 by expanding of the bag-like member 130. The insulating oil is returned from the gas extraction chamber 110 to an electrical device 10 by the expansion of the bag-like member 130.SELECTED DRAWING: Figure 1
