1) Density is a measure of the specific gravity of SF6 gas in a closed container, which is independent of pressure and temperature changes. That is, the gas in the container does not leak or add gas into it, and its density state is constant. The internal pressure will change with the change of the ambient temperature.

SF6 positive pressure air respirator belongs to the barrier type respiratory protection supplies, is a kind of self-contained open air respirator, mainly used in fire fighting, chemical industry, ships, petroleum, smelting, factories and mines, etc., so that firefighters or rescue personnel can safely carry out fire fighting, rescue and relief work in the harsh environment full of smoke, gas, steam or hypoxia. Especially in the power SF6 switch station, when the explosion-proof film breaks or ot

When a beam of infrared light with a continuous wavelength is irradiated on a substance, if the vibration frequency of a group in the substance molecule is the same as the frequency of light, the two will resonate, that is, the group absorbs the infrared light at this frequency; On the other hand, matter does not absorb light energy. The light through the material through the monochromator dispersion, its frequency is expressed by wave number or wavelength, its transmission degree is expressed b

In the GIS disassembly should pay attention to the following safety protection: 1, disassembly maintenance, maintenance personnel should wear special work clothes (protective clothing), hats, scarves. Gas mask or dust mask, using thin latex gloves or nylon gloves (not cotton yarn), goggles and special work shoes; 2, in and out of SF6 maintenance room, use the fan or compressed air to wash the whole body; 3. Wash hands frequently and the exposed part of the human body during work breaks, and pay
