Description
Technical field:
The utility model relates to electromechanical industries high-voltage switch gear field, particularly circuit breaker.
Background technology:
Be hydraulic mechanism and pneumatic mechanism in breaker open operation, closing operation dynamical system at present, have oil, gas to produce contaminated environment in the use, hydraulic mechanism and pneumatic mechanism structure more complicated in addition, volume is big, and influenced greatly by ambient temperature, and the area of application is restricted.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned not enough problem, provides a kind of spring operating mechanism, simple in structure, compact, safety non-pollution.
The technical scheme that the utility model is adopted for achieving the above object is: spring operating mechanism, be installed with closing coil and switching winding on the support, closing coil dynamically is connected with the combined floodgate pallet, the combined floodgate pallet is rotatably installed on the axle, axle is fixed on the support, the combined floodgate pallet dynamically is connected with the maintenance pallet that closes a floodgate, close a floodgate and keep combined floodgate backing pin one end on the pallet to be fixed on the support, one end dynamically is connected on the ratchet, ratchet is connected with switching-in spring by the spring pull bar, and pawl axis links by gear and motor; Switching winding dynamically is connected with the separating brake pallet, and the separating brake pallet keeps pallet dynamically to be connected with separating brake, and the separating brake backing pin dynamically is connected with cam, cam dynamically is connected with roller, cam and ratchet are with being contained on the ratchet shaft, and roller is coaxial rack-mount with connecting lever, and big connecting lever termination connects tripping spring.
Described cam is connected with freewheel clutch, freewheel clutch is that the freewheel clutch irreversible control is housed in the ring flange, it is made of special-shaped voussoir, retainer and back-moving spring, retainer surrounds circumferential, special-shaped voussoir is contained on the retainer, have spring groove on the special-shaped voussoir, back-moving spring is housed in the spring groove.Described special-shaped voussoir is shaped as the off-centre operation cylindricality.
The utility model mechanical feature is: the used kinetic energy that divides, closes a floodgate is all from spring, and is simple in structure, safe and reliable.Each rotatable parts all adopts bearing and self lubrication bearing, rotates flexibly, reduces operating work.This mechanism replaces hydraulic mechanism and the pneumatic mechanism that uses in the like product fully, does not have oil, gas generation, and is free from environmental pollution, Maintenance free.Compare with hydraulic mechanism, pneumatic mechanism, simple in structure, compact, not influenced by ambient temperature, applied widely, use safety and reliability.This product mainly is used in 72.5KV, 126KV primary cut-out, and for circuit breaker branch, closing operation provide kinetic energy, its mechanical property has directly determined the circuit breaker performance.

Embodiment:
Spring operating mechanism as shown in Figure 1, spring operating mechanism, be installed with closing coil 3 and switching winding 1 on the support 7, closing coil dynamically is connected with combined floodgate pallet 4, the combined floodgate pallet is rotatably installed on the axle, axle is fixed on the support, the combined floodgate pallet dynamically is connected with the maintenance pallet 11 that closes a floodgate, close a floodgate and keep combined floodgate backing pin 12 1 ends on the pallet to be fixed on the support, one end dynamically is connected on the ratchet 13, ratchet is connected with switching-in spring 15 by the spring pull bar, and pawl axis 16 links by gear and motor; Switching winding dynamically is connected with the separating brake pallet, separating brake pallet 2 keeps pallet 10 dynamically to be connected with separating brake, separating brake backing pin 9 dynamically is connected with cam 6, cam dynamically is connected with roller 5, cam and ratchet are with being contained on the ratchet shaft 17, roller is coaxial rack-mount with connecting lever, big connecting lever 8 terminations connect tripping spring 14, cam is connected by freewheel clutch, and freewheel clutch is that the freewheel clutch irreversible control is housed in the ring flange, and it is by the special-shaped voussoir 18 of off-centre operation cylindricality, retainer 19 and back-moving spring 20 constitute, retainer surrounds circumferential, special-shaped voussoir is contained on the retainer, has spring groove on the special-shaped voussoir, and back-moving spring is housed in the spring groove.
Sub-switching operation as shown in Figure 2 during use, it is closing position (a switching-in spring energy storage state): charged after the tripping electromagnet coil is accepted sub-gate signal, the sincere son of separating brake is impacted in the iron core action, the separating brake pallet rotates to clockwise direction, discharge separating brake and keep pallet, separating brake keeps pallet also to rotate to clockwise direction, and release separating brake backing pin, connecting lever rotates to counter clockwise direction under the effect of tripping spring, connecting lever moves downward by the pull bar that connected link rod drives in the arc extinguishing unit, makes breaker open operation.
The behaviour that closes a floodgate uses as shown in Figure 3, and it is separating brake position (a switching-in spring energy storage state):
It is charged after sequence number 3 making electromagnet coils are accepted switching signal, the iron core action is impacted the sincere son that closes a floodgate and is rotated to clockwise direction, discharging closes a floodgate keeps sincere son, close a floodgate and keep pallet to be rotated counterclockwise release combined floodgate backing pin, the switching-in spring of cam same axis discharges, drive cam and radiate rotation clockwise, promoting the big connecting lever of rotation during cam rotation rotates, and the compression tripping spring, connecting lever moves upward by pull bar in the link rod drive arc extinguishing unit, makes breaker closing, to be connected in the tripping spring energy storage of connecting lever simultaneously, electric motor starting makes the pawl axis rotation during energy storage, and the ratchet on the eccentric pawl axis alternately meshes with ratchet in rotation, and ratchet rotates counterclockwise, by the energy storage of pull bar example switching-in spring, after crossing the dead-centre position, ratchet shaft is given anticlockwise rotation side square by switching-in spring, stops by the combined floodgate backing pin pallet that closed a floodgate.Prepare against separating brake usefulness next time.
