A: SF6 quantitative leak detector (Winfoss-C1) adopts the principle of high frequency ionization measurement: When the air contains different concentrations of sulfur hexafluoride gas or various halogen gases, the degree of ionization under the action of high frequency electromagnetic field is different.

SF6 laser imaging testing instrument is mainly composed of laser emission system, laser cooling system, low light level electric receiving system, signal conversion amplification and processing system, display unit and power supply. The advantage of SF6 laser imaging detector is that it can detect leaks when SF6 electrical equipment is running, and it can detect very small leaks quickly and far away. However, the device is expensive, large and bulky, and is not easy to operate outdoors.

SF6 gas mass is heavier than air, in the case of not fully mixed with air, SF6 gas has a tendency to deposit in low places, such as cable trench, indoor bottom, the bottom of the container, etc. In these places where there may be a large amount of SF6 gas deposits, it is easy to be hypoxic, and there is a danger of suffocation. Therefore, most countries stipulate that the maximum allowable concentration of SF6 gas in the workplace for operation and maintenance is 1000UL/L.

In order to prevent the lack of oxygen caused by the retention of SF6 gas in the equipment room due to leakage, or the existence of trace harmful substances to endanger the health of personnel, SF6 and oxygen content should be tested regularly. The oxygen content of the air should be greater than 18%.

Density refers to the mass ρ=m/V(kg/m^3) per unit volume of a specific substance under certain conditions, for SF6 electrical equipment in a chamber gas is sealed in a fixed and unchanged container, if there is no leakage, the gas mass in the chamber will not change, the gas density will not change, such as If the gas chamber is lowered, it indicates that the gas chamber is leaking. Since the size of the density is independent of the change in temperature, a density meter can be used to monitor
