Problems solved by technology
However, the production process of sulfur hexafluoride in the prior art inevitably makes the gas mixed with impurity components such as mineral oil particles, which affects the purity of sulfur hexafluoride gas. In view of this, in order to ensure the application of sulfur hexafluoride gas In order to ensure the safety of the power system, the content of mineral oil must be detected
However, currently SF 6 The standard measurement method of mineral oil content in gas cannot be directly calibrated, resulting in the inability to judge the accuracy of the detection data, which brings hidden dangers to the safe construction and production of the power grid, and needs to be improved urgently

The invention discloses a preparation device and preparation method of mineral oil content standard gas in SF6 gas. The device comprises a thermostatic bath and a cover body used for sealing the thermostatic bath, wherein an accommodating groove of the thermostatic bath accommodates and heats machine oil; an air inlet pipeline and an air outlet pipeline both communicated with the thermostatic bath are respectively arranged at the front end and back end of the cover body; pure SF6 air enters the accommodating groove through the air inlet pipeline, blows the oil surface and is exhausted from the air outlet pipeline; the air outlet pipeline is connected with a mineral oil content-detecting device. The device solves the standard magnitude-transmitting problem when using a device for detecting the mineral oil content in SF6 gas to measure the mineral oil content, can directly calibrate the device for detecting the mineral oil content in SF6 gas to enable the mineral oil-in-SF6-gas content-detecting device to be more accurate in measured data, has the characteristics of being short in time consumption, good in effect, convenient to use, and the like, and provides a powerful safeguard for the safe operation of electrical equipment.
Description
technical field [0001] The present invention relates to a kind of SF 6 The invention relates to a preparation device and method for standard gas of mineral oil content in gas; it belongs to the technical field of power system application. Background technique [0002] Sulfur hexafluoride (SF 6 ) Gas has excellent electrical insulation and arc extinguishing properties compared with air, so it has been widely used in electrical equipment, and can be used as insulating materials for high-voltage switches, large-capacity transformers, and high-voltage cables. However, the sulfur hexafluoride production process in the prior art inevitably makes the gas mixed with impurity components such as mineral oil particles, which affects the purity of sulfur hexafluoride gas. In view of this, in order to ensure the application of sulfur hexafluoride gas In order to ensure the safety of the power system, the content of mineral oil must be detected. However, currently SF 6 The standard me...
