Medium, the on-off function of power circuit is realized by sealing a pair of contacts in a vacuum, when it disconnects the electric current of certain numerical value
When, dynamic/static contact separate moment, current constriction to contact just separate a little on, occur resistance between electrode acutely increase and
Temperature is improved rapidly, until there is the evaporation of electrode metal, while form high electric-field intensity, cause extremely strong strong transmitting and
Gap breakdown, produces vacuum arc, when power current is close to zero, while be also the increase of clearance between open contacts, vacuum arc etc.
Gas ions spread to surrounding quickly, and after arc current zero passage, the medium of contact gap is changed into insulator from electric conductor rapidly, then
Electric current is broken.Due to the special tectonic of contact, contact gap can produce appropriate longitudinal magnetic field during arcing, and this magnetic field can make
Electric arc is evenly distributed on contact surface, maintains low arc voltage, so that vacuum interrupter has dielectric strength after arc higher
Resume speed, small arc energy and small corrosion rate.So, just improve the ability of vacuum interrupter drop-out current and make
Use the life-span.Breaker 12 directly carries out arc extinguishing treatment, it is to avoid because non-SF6 gases are under insulation effect, and arc extinguishing is incomplete
