Description

Technical Field

[0001] The utility model relates to the technical field of GIS comprehensive monitoring, in particular to a new type of GIS comprehensive on-line monitoring device. Background Art

[0002] A GIS partial discharge comprehensive on-line monitoring device (publication number: CN111505457B) disclosed on the Chinese patent website, although solves the technical problem of high false alarm frequency of the existing GIS partial discharge on-line detection device, still has the problem of poor waterproof and moisture-proof performance.

[0003] In the actual use process, although the GIS equipment has a reliable sealing system, the diameter of water molecules is smaller than that of SF6 gas, and water can still penetrate in.

[0004] Moreover, the GIS equipment may come into contact with moisture during the manufacturing, transportation, installation and maintenance processes, and the moisture will be immersed into each component of the equipment. The insulating parts of the GIS equipment itself contain moisture and will slowly release during operation. The adsorbent in the GIS equipment itself also contains moisture, which will make the SF6 gas in the gas chamber contain moisture. The gas in the GIS equipment contains moisture, which will cause harm to the insulating parts of the electrical equipment. Moisture in the electrical equipment will produce condensed water on the surfaces of the insulating parts and metal components, causing surface flashover.

[0005] SF6 gas is a colorless, odorless, non-flammable, non-toxic inert gas, with excellent insulation performance and will not age or deteriorate. When the moisture content in SF6 exceeds a certain level, it will cause chemical corrosion of the equipment. When there is more moisture, under the action of arc and corona, the SF6 gas will decompose to generate hydrofluoric acid and sulfurous acid, which have strong corrosive effects. These low-fluorine compounds are highly toxic gases and will cause damage to insulating materials. Content of the Utility Model
