Portable trace moisture detection device

Abstract

The invention provides a portable trace moisture detection device which comprises a detection unit, a sealing and pre-activation unit, a control and data processing unit and a display and man-machine interaction unit, wherein the sealing and pre-activation unit comprises a sealed balancing tank and a flow guide tube penetrating through the sealed balancing tank; an opening is formed in the sidewall, positioned in the sealed balancing tank, of the flow guide tube; a mechanism for enabling a sensor in the flow guide tube to be in contact with and be isolated from air in the sealed balancing tank is arranged at the opening; the detection unit is arranged in the flow guide tube; a drying agent is arranged in the sealed balancing tank outside the flow guide tube; the control and data processing unit is arranged outside the sealed balancing tank, and is electrically connected with the detection unit, the sealing and pre-activation unit and the display and man-machine interaction unit. The portable trace moisture detection device is simple in structure, and can be used for rapidly and accurately realizing trace moisture detection.

Description

technical field [0001] The invention relates to detection technology, in particular to a portable micro-water detection device. Background technique [0002] SF6 gas is widely used in high-voltage electrical equipment due to its excellent arc extinguishing performance and high-strength insulation performance. However, long-term high-voltage operation of SF6 gas will lead to decomposition, and its decomposition products will react with the moisture in it to produce toxic and harmful products, which will not only reduce the electrical performance of SF6, but also pose a threat to human health when these toxic and harmful products are discharged into the atmosphere. , Inhalation of a very small amount of some products can cause death, so it is necessary to detect the water content of SF6 gas, analyze its changing trend and prevent it in advance to avoid major accidents. [0003] The detection probes of traditional portable micro-water detection devices are generally exposed to...
