Description

SF6 gas concentration on-line measuring device

Technical Field

The utility model relates to a gaseous technical field of sulfur hexafluoride specifically is a SF6 gas concentration on-line measuring device.

Background

Pure SF6 gas is generally recognized as non-toxic. There are a few accompanying products in the SF6 production process, where S2F10 is a recognized highly toxic gas, but it can be completely removed by purification. Although the pure SF6 gas is non-toxic, the concentration of SF6 gas is prevented from rising to oxygen deficient levels in the field. The density of SF6 gas is about five times that of air, and SF6 gas, if leaked, will tend to deposit in depressions such as cable trenches. Excessive concentrations present a choking hazard and are considered in the design of indoor ventilation units. SF6 gas can be mixed with air by convection, but at a slow rate. Once mixed, the gases form a mixed gas of SF6 and air, which does not separate again.

When detecting SF6 gas concentration, need use the detecting instrument, through the vacuum pump in with air suction instrument, detect it, simultaneously because in different environment, can have different substances in the air, these substances may be to influencing the testing result, and when sediment matter was too much like dust in the air simultaneously, still may block up the trachea, the influence is used.
