Beschreibung
Zusammenfassung:	The invention discloses a flexible tracking method for dissolved gas in transformer oil. The method comprises the following steps: 1) determining a tracking coefficient according to the gas production rate of characteristic gas in oil detected last time of a transformer; 2) determining a tracking coefficient according to the operating age limit of the transformer; 3) determining a tracking coefficient according to the operation condition of the transformer; 4) determining a tracking coefficient according to the average oil temperature of the transformer; according to the method, the tracking period of the dissolved gas in the transformer oil can be determined according to various operation parameters of the transformer, and optimization is achieved. The method includes the steps of 1, determining the tracking coefficient according to the voltage class of the transformer, 2, determining the comprehensive tracking coefficient of the transformer according to the subitem tracking coefficient, and 3, determining t
