The device is used for accurately detecting the content of carbon tetrafluoride in the electrical equipment with environmental friendliness. The invention further discloses a method for detecting the content of carbon tetrafluoride in the electrical equipment.

Description

technical field [0001] The invention relates to the field of power system monitoring, in particular to a device for detecting the content of carbon tetrafluoride in electrical equipment. In addition, the invention also relates to a method for detecting the content of carbon tetrafluoride in the electrical equipment. Background technique [0002] Sulfur hexafluoride (SF 6 ) is a colorless, odorless, non-toxic, non-flammable inert gas, which is widely used in gas insulated circuit breakers, GIS gas insulated substations, transformers and Transformers and other electrical equipment. The above-mentioned sulfur hexafluoride (SF 6 ) gas electrical equipment will produce overheating faults and discharge faults (including: arc discharge, spark discharge and partial discharge, etc.) during actual application. Under the above fault conditions, sulfur hexafluoride (SF 6 ) will undergo a decomposition reaction. If it is near the insulating medium, it will also react to generate carb...
