Embodiment Construction
[0020] The specific embodiment of the present invention is as figure 1 shown.
[0021] The online detection system for dissolved gas in transformer oil in this embodiment consists of a gas separation part, an optical part, and an online control and analysis part. The gas separation part includes a gas permeable membrane 3, a gas conduit 4, an electromagnetic valve 5, an air pump 6, and a gas chamber 7; Spectrum analyzer 24 and other auxiliary optical components, etc. The online control and analysis part includes a control box 16 and a computer host 21; the control box 16 is composed of a time-sharing controller 17, a Rayleigh filter controller 20, a valve controller 18, and an air pump controller 19. The host computer 21 controls the four controllers in the control box through the control software; obtains the spectrum signal of the spectrum analyzer 24 through the spectrum analysis software and performs gas analysis.
