Description

Technical Field

[0001] The utility model relates to an SF6 density micro-water sensor, in particular to an SF6 density micro-water sensor with a display, belonging to the technical field of sulfur hexafluoride. Background Art

[0002] Sulfur hexafluoride is an inorganic compound with the chemical formula SF6. It is a colorless, odorless, non-toxic, and non-flammable stable gas at room temperature and pressure. It has high stability. When the temperature does not exceed 180°C, its compatibility with electrical structural materials is similar to that of nitrogen. Due to its high electrical insulation strength, it is used as an arc-extinguishing medium in high-voltage circuit breakers. In ultra-high voltage and extra-high voltage circuit breakers, SF6 has replaced oil as the arc-extinguishing medium.

[0003] The SF6 micro-water density sensor, patented CN214201061U, effectively solves problems such as inconvenient installation, low efficiency, and inaccurate detection. It includes a base with an air chamber within it. A first self-sealing joint is threadedly connected to the left end of the base. An air intake duct connected to the air chamber is located within the first self-sealing joint, and a second self-sealing joint is threadedly connected to the right end of the base. This innovative sensor features a clever structure, excellent sealing, and the ability to monitor SF6 micro-water density online. It is simple to operate, improves the accuracy of test data, and is safe and stable.

[0004] When using sulfur hexafluoride gas to extinguish arcs in electrical equipment, it is necessary to monitor the density, humidity, and temperature of the sulfur hexafluoride inside the equipment. Although the device in the above patent reduces the difficulty of detection, it requires external equipment to read the detection data, which reduces the efficiency of on-site detection. To this end, we provide an SF6 density and micro-water sensor with display to solve the above problems. Utility Model Content
