When circuit breaker is in "on" position and prepares separating brake, the dynamic/static contact closure of vacuum interrupter at this moment.When circuit breaker is received the separating brake order, under the effect of spring operating mechanism 22, lead agency output toggle arm 21, by connecting rod 20 the input connecting lever 18 of circuit breaker is moved clockwise, the moving contact insulated tension pole 16 that drives breaker vacuum arc extinguish chamber 13 simultaneously moves downward, make the moving of arc extinguish chamber, static contact is under the effect of operating mechanism during charged separation, between contact, will produce vacuum arc immediately, because the special construction of contact, in the contact gap, produce vertical magnetic field simultaneously, vertical magnetic field impels vacuum arc to remain diffused, and be evenly distributed on the contact surface burning, keep lower arc voltage.At the electric current of conducting nature during through zero crossing, remaining in ion, electronics and metallic vapour in the gap will be compound rapidly or condense upon on contact surface and the screened housing, and the dielectric strength between the arc extinguish chamber fracture is recovered rapidly, arc extinction, and the galvanic circle is cut off.
Its principle of work is:
1) sub-switching operation
The switching-in spring of mechanism and tripping spring 19 equal own energy storage during combined floodgate, it is charged after switching winding is received the separating brake order, trip electromagnet is by excitatory, mechanism's output toggle arm 21 and circuit breaker input connecting lever 18 apply clockwise moment of rotation by tripping spring 19, under the effect of moment of rotation, mechanism's output toggle arm 21 and circuit breaker input connecting lever 18 are driven by connecting rod 20 and move clockwise, the moving contact insulated tension pole 16 that drives the breaker vacuum arc extinguish chamber simultaneously moves downward, until finishing sub-switching operation.
2) closing operation
It is charged after closing coil is received the order of closing a floodgate, making electromagnet is by excitatory, mechanism's output toggle arm 21 and circuit breaker input connecting lever 18 apply under the effect of anti-clockwise moment of rotation at switching-in spring, mechanism's output toggle arm 21 and circuit breaker input connecting lever 18 are driven by connecting rod 20 and carry out the anticlockwise direction motion, drive moving contact insulated tension pole 16 upward movements of breaker vacuum arc extinguish chamber simultaneously, until finishing closing operation.
Needs according to user's operation can have multiple pattern, as the circuit breaker two ends solid envelope support type current transformer are installed simultaneously, and perhaps any end is installed and sealed support type current transformer admittedly.
As shown in Figure 4, bipolar isolation switch with seal column support type transformer module block construction scheme drawing admittedly, described bipolar isolation switch with seal column support type transformer bank integrator admittedly, the first bipolar isolation switch moving contact 31 is fixed on first with outlet splicing ear 1 and seals column support type voltage transformer 2 upper ends admittedly, and bipolar isolation switch moving contact 31 is connected with first rotating shaft 33 by first insulated tension pole 32; The first rotating shaft other end is connected by first output toggle arm 35 of first connecting rod 34 with bipolar isolation switch mechanism control box 7.
Shown in Figure 4 is that the bipolar isolation switch moving contact is a closing position, when first bipolar isolation switch 3 disconnects, first output toggle arm 35, first connecting rod 34 by the first bipolar isolation switch operating mechanism 7 drive first rotating shaft 33 and rotate counterclockwise, and drive first insulated tension pole 32 and move downward, bipolar isolation switch moving contact 31 rotates counterclockwise under the drive of first insulated tension pole 32, separate fully with the first bipolar isolation switch static contact 23 that is installed in solid envelope breaker module unit until bipolar isolation switch moving contact 31, finish sub-switching operation.When first bipolar isolation switch 3 closes a floodgate, first output toggle arm 35, first connecting rod 34 by the first bipolar isolation switch operating mechanism 7 drive first rotating shaft 33 and clockwise rotate, and drive first insulated tension pole, 32 upward movements, bipolar isolation switch moving contact 31 clockwise rotates under the drive of first insulated tension pole 32, closed fully until bipolar isolation switch moving contact 31 with the first bipolar isolation switch static contact 23 that is installed in solid envelope breaker module unit, finish closing operation.
The course of action of second bipolar isolation switch 26 is identical with first bipolar isolation switch 3.
