[0002] In the field of high voltage, ultra-high voltage and ultra-high voltage, SF6 gas has become almost the only insulating and arc-extinguishing medium for circuit breakers and GIS. With the extensive application of SF6 equipment, on the one hand, power production has become safer and more reliable, and on the other hand, the possibility of SF6 gas itself causing harm to the environment, equipment, and especially the personal health and safety of on-site workers is increasing. In order to ensure the normal operation of equipment and the personal health and safety of on-site workers, effective measures must be taken to monitor SF6 gas leakage in the equipment area to prevent accidents.

[0003] At present, the detection of sulfur hexafluoride is mostly carried out by using a gas detection sensor to measure its concentration by utilizing the absorption characteristics of sulfur hexafluoride to a specific infrared wavelength. When installing the gas detection sensor in an installation box, the gas detection sensor is mostly fixed by multiple bolts. In order to extend the service life of the gas detection sensor, the gas detection sensor needs to be removed regularly for inspection and maintenance. However, when installing and disassembling, the bolts need to be repeatedly turned until all the bolts are removed before the gas detection sensor can be removed. In addition, this installation method is difficult to adjust the installation position according to the actual installation situation, which is inconvenient to use. Utility Model Content

After the fixation is completed, according to the actual installation situation, the plug-in rod 32 is inserted into the hole on the surface of the fixing plate 31.
