The use of SF6 gas in high voltage electrical equipment is due to 4-6 times the atmospheric pressure (usually 0.4-0.6MPa), resulting in leakage is inevitable. The level of insulation and arc extinguishing is directly affected, and the operation safety of equipment is threatened.
SF6 gas itself is non-toxic, but because it is the heaviest gas found so far, the normal density is about 6 times that of air, so it is easy to cause hypoxia in the low area after leakage. Threat to personal safety.
Most of the decomposing substances under the high voltage arc belong to highly toxic substances, and once the leakage will directly harm the personal safety entering the site.
In the 1997 Kyoto Agreement to prevent global warming, six gases, including SF6, were classified as greenhouse gases. SF6 gas is very stable in the atmosphere and is not easily decomposed, and can exist for 2,500 years without decomposition under normal conditions, and its impact on the greenhouse effect is 34,000 times that of CO2. Therefore, the leakage or arbitrary discharge of SF6 gas will seriously pollute the atmosphere.
