Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment, in particular to a SF6 digital density analysis device. 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. SF6 gas has the characteristics of high insulation strength and good arc extinguishing performance. It is currently the preferred insulating medium for high-voltage equipment. In order to ensure the safe operation of high-voltage equipment, the density, pressure and other parameters of SF6 gas in high-voltage equipment must be strictly monitored.

[0003] SF6 gas density relay is a device used in high-voltage electrical equipment to monitor SF6 gas density. It can send out alarm signals and lockout signals in time for gas leakage in electrical equipment, which can timely and effectively avoid accidents and ensure the safe operation of high-voltage electrical equipment. However, the SF6 gas density relay installed on site often does not work. As time goes by, it will become inflexible and have poor contact points. Therefore, it is necessary to regularly detect and analyze the SF6 gas density relay.

[0004] For example, the SF6 gas density relay detection device with application number 202223030262.1 not only improves the convenience of the detection device, but also eliminates the need to discharge SF6 gas to the external environment, and can recycle SF6 gas, thus protecting the environment. However, the device is less portable, and it is difficult to store the ventilation hose, which is prone to scattering.

[0005] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an SF6 digital density analysis device is proposed. Utility Model Content
