Abstract
To study the low temperature liquefaction characteristics of SF6 for the operation security of electric equipments in cold area, the writer carries out the low temperature liquefaction test of SF6 respectively in laboratory and outdoors by using SF6 gas low temperature experimental apparatus. According to the results of the test and the Beattie-Bridgman SF6 empirical formula, SF6 gas state parameter curve is plotted and a concise practical SF6 gas state parameter formula is got. This formula is more applicable to electric equipments outdoors. The results show that SF6 gas is easier to liquefy in cold area, and the liquefaction temperature of SF6 gas is in proportion to gas pressure. So the liquefaction temperature of electric equipments operated in cold area should not be higher than the lowest area temperature. Otherwise, measures must be taken to prevent SF6 gas from liquefaction.
