Problems solved by technology

However, since SF in GIS 6 When the gas is partially discharged, the concentration of the decomposition product is very low, which is on the order of μL/L. In addition, the infrared light source is generally weak and the sensitivity of the infrared detector is low, which makes the detection of trace gas components very difficult.
The gas cell of the existing Fourier transform infrared detection spectrometer such as the 0.1-meter short-path gas cell produced by Tianjin Tianguang Optical Instrument Co., Ltd., such as figure 1 As shown, the short optical path gas c...

Description

technical field [0001] The invention belongs to the technical field of gas infrared absorption spectrum analysis, in particular to sulfur hexafluoride (SF 6 ) Gas infrared absorption spectroscopic analysis device and method. Background technique [0002] Gas insulated switchgear (GIS), with sulfur hexafluoride (SF 6 ) gas as an insulating medium has the advantages of high dielectric strength, stable operation, small footprint and small maintenance workload. It is more and more widely used in power systems, especially in the construction and transformation of large and medium-sized cities. However, judging from the operating conditions in recent years, many problems have occurred in the use of GIS at home and abroad, among which insulation faults are the main ones. The most common feature of insulation faults is that the insulating medium in GIS has localized faults before complete breakdown. Discharge (PD). Under the action of discharge, SF 6 The gas decomposes, and the ...
