Embodiment 1
When detecting the micro-water and decomposed components in the GIS, the gas to be tested is filled into the detection cell, and the infrared light source of the wavelength band corresponding to the characteristic peaks of the micro-water and decomposition components is used to inject the infrared light into the detection cell, and the infrared light is injected into the detection cell. A photoelectric sensor is arranged on one side to collect infrared light intensity signals and convert them into electrical signals for transmission to the signal processing device.
[0024] In the signal processing device, the device processes the collected original signal of the gas to be measured into a second harmonic signal that can characterize the concentration of the gas to be measured.
[0025] After the second harmonic signal is generated, the second harmonic signal is denoised. Since the second harmonic signal is composed of continuous voltage signals, the invention takes the continuou...
