Embodiment
In order to better understand the technical solution of the utility model, below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1-2, a kind of circuit breaker drives operating mechanism, comprise shell 1, static stake 3 is provided with bottom shell 1, static stake 3 is a hermetic type cavity, static stake 3 inside is provided with static iron core, static iron core outside is tied with the contrary loop of winding direction I 11 and loop II 12, shell 1 top is provided with the conduction axis 2 that can move up and down, conduction axis 2 is hermetic type cavity, conduction axis 2 inside is provided with conduction iron core, conduction iron core outside is tied with loop III 13, left iron core 4 is provided with above shell 1 inner left wall, left iron core 4 outside is tied with loop IV 14, right iron core 5 is provided with above inwall on the right side of shell 1, right iron core outside is tied with loop V 15, left iron core 4 and right iron core 5 top linking springs and pin 8 all successively, cover top portion is provided with right baffle-plate 6 and right baffle plate 7, right baffle-plate 6 is respectively equipped with on right baffle plate 7 through hole 8 mating with pin and use, the outer wall of conduction axis 2 is provided with the hole clipping 10 corresponding with through hole.Static stake adopts iron core loop instead of traditional permanent magnet, and which ensure that the growth along with service time, suffered by static stake, magnetic can't be affected.
Static stake top is provided with elastic buffering pad 16.Reduce the impact of hard hit on conduction axis and static stake deformation.
Elastic buffering pad is provided with bottom conduction axis.Reduce the impact of hard hit on conduction axis and static stake deformation.
Distance between left iron core and right baffle-plate be less than spring undeformed time length.When ensure that gate-dividing state, pin pushes in the hole clipping of conduction axis by spring, ensure that continuing of gate-dividing state under off-position.
Static stake and conduction axis are coaxial distribution.Minimise wear when ensure that separating brake and feed motion between the static stake of uniform force and conduction axis.
During use, when circuit breaker receives reclosing command, loop I is consistent with loop III winding direction, two coils are energized simultaneously, loop II is in off-position, now due to Ampere's law, the loop of two energisings produces consistent magnetic field, direction, namely the power between static stake and conduction axis is attraction, conduction axis is impelled to move downward, when two elastomeric material cushion contact then play cushioning effect, reduce conduction axis and the wearing and tearing of static stake owing to producing under hard hit power, closing speed due to for attraction speed fast, a moderating process is had owing to being provided with elastomeric material cushion pad, which increase combined floodgate performance.After power-off, due to Action of Gravity Field, close a floodgate and keep.
When circuit breaker receives separating brake instruction, loop I is in off-position, loop II and loop III are energized simultaneously, and now two hot-wire coils produce contrary magnetic field, direction, are namely repulsive force between conduction axis and static stake, because huge repulsive force impels conduction axis to move upward, complete separating brake, when after power-off, left iron core and right iron core cause disappearing to the attraction of spring due to power-off, pin is pushed hole clipping by spring, and conduction axis is fixed on gate-dividing state.
By reference to the accompanying drawings embodiment of the present utility model is described although above-mentioned; but the restriction not to the utility model protection range; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection range of the present utility model.
