Arc extinguishing theory of load switch
SF6 gas has good arc extinguishing function. In order to extinguish voltaic arc quickly, the switch in the process of interrupting current, it can produce voltaic arc when the fixed contact and moved contact separate. Then, because of the magnetic field action of permanent magnet, driving voltaic arc moves fast to prolong voltaic arc and to combine with SF6 gas, then dissociation and cooling. When the current to be zero, it extinguishes. The double rents have the function of insulation to separate rents. Permanent magnet revolved arc theory, which is low operate power, better arc extinguishing, low contact terminal burn, prolong the electric life span.
