Summary:PROBLEM TO BE SOLVED: To provide a method of inhibiting degradation of phosphate ester oil that is able to inhibit degradation of phosphate ester oil, and an apparatus for inhibiting degradation of phosphate ester oil.SOLUTION: It is possible to inhibit degradation of phosphate ester oil by supplying active hydrogen from a hydrogen supplying module 13 to phosphate ester oil that comprises phenol derivatives produced by storage or usage of the oil and quinones that have been derived from phenol derivatives and hydrogenating the quinones. Namely, an amount of quinones in the phosphate ester can be reduced because the quinones can be restored to phenol derivatives by hydrogenating and reducing the quinones. Consequently, degradation of phosphate esters can be inhibited because polymerization due to a reaction of the phenol derivatives with the quinones is prevented.SELECTED DRAWING: Figure 1 【課題】リン酸エステル油の劣化を抑制できるリン酸エステル油の劣化抑制方法及びリン酸エステル油の劣化抑制装置を提供すること。【解決手段】貯蔵や使用等によって生成したフェノール誘導体とフェノール誘導体から生成したキノン種とを含むリン酸エステル油に対して、水素供給モジュール13から活性水素を供給して、キノン種に対する水素添加を行うことにより、リン酸エステル油の劣化を抑制することができる。つまり、キノン種に水素添加して還元することによってフェノール誘導体に戻すことができるので、リン酸エステル油中のキノン種の量を低減することができる。その結果、フェノール誘導体とキノン種との反応によってポリマーが生成することを抑制できるので、リン酸エステル油の劣化を抑制することができる。【選択図】図1
