Operation principle below in conjunction with detailed description of the drawings the utility model.
First element: contactor closes a floodgate
External command gets through deciliter coil 13 ' that the sensitive switch 23 ' in the low voltage control part assembly passes in drive part assembly, the drive part assembly; Produce an electromagnetic force that makes progress; Driving moving iron core 10 ' moves upward; Move upward through axle 11 ' and the moving contact that the insulated tension pole that is attached thereto 19 ' promotes in the vacuum interrupter 1 ' again, and closed with fixed contact, and the adhesive effect through permanent magnet 16 ' makes the dynamic/static contact in the vacuum interrupter 1 ' remain closure state again; Thereby make input terminal 2 ' and lead-out terminal 9 ' conducting in the high-pressure section assembly, with the electric component of high-tension electricity introducing needs.
Second action: contactor separating brake and arc extinguishing
External command gets through deciliter coil 13 ' that the sensitive switch 23 ' in the low voltage control part assembly passes in drive part assembly, the drive part assembly; Produce a downward electromagnetic force; Driving moving iron core 10 ' moves downward; Move downward through axle 11 ' and the moving contact that the insulated tension pole that is attached thereto 19 ' spurs in the vacuum interrupter 1 ' again, add the effect of the tripping spring in the vacuum interrupter 1 ', the rapid separating brake of contactor.Because the dynamic and static contact in the vacuum interrupter 1 ' is to be encapsulated in the airtight container of a glass annulus formation, when dynamic and static contact separates, in the contact slit, forms the plasma of metallic vapour.When current over-zero, metallic vapour reduces, and vacuum state appears in final contact gap, because the vacuum medium has very high dielectric strength and very fast medium recovery speed, the recovery voltage between the contact can not make gap breakdown, and circuit is just by reliable disjunction.
