Abstract
The invention relates to a spring operating mechanism of a high-voltage circuit breaker. The spring operating mechanism consists of a rack wheel, a pinion, an energy storage shaft, a floating toothed bar, a pin shaft and a reset spring; the pinion is arranged at the energy storage shaft; parts of teeth of the rack wheel are removed at the mutual engagement portion of the rack wheel and the pinion; and the base body inside portion with no tooth is processed into the groove-shaped portion and the floating toothed bar, the pin shaft, and the reset spring are installed in the groove. The floating toothed bar has three teeth, wherein the parameters of the teeth are identical with that of the rack wheel. The floating toothed bar rotates around the pin shaft under the force of the reset spring. With the mechanism, all problems of opening and closing operations including closing spring energy storage and closing spring energy releasing can be solved, so that the energy storage-closing operation-opening operation process required by the spring operating mechanism of the circuit breaker can be executed correctly and reliably.
Description
Technical field:
The present invention relates to primary cut-out, be specifically related to a kind of spring operating mechanism of primary cut-out.
Background technology:
The requirement of circuit breaker operation mechanism according to standard divide, closing operation, to complete the disjunction of power circuit and connection.
Sub-switching operation process: because tripping spring is strong, connecting lever has the moment turning clockwise around output shaft, after separating brake trigger winding excitation, clashing into separating brake release is rotated counterclockwise, locking bolt A is by pin A jack-up, now connecting lever turns clockwise, and by connecting rod A, drives circuit breaker movable contact to move to open position.
Closing operation (is that switching-in spring energy discharges, lower same) process: after combined floodgate trigger winding excitation, clashing into combined floodgate trigger is rotated counterclockwise, discharged locking bolt B, removed the interception to pin B, the moment that switching-in spring produces can drive gear wheel and cam to turn clockwise around camshaft, and cam can promote roller and connecting lever is rotated counterclockwise around output shaft, by connecting rod A, drives circuit breaker movable contact to move to closing position.
Switching-in spring accumulation of energy process: by reduction gearing and freewheel clutch, pinion is rotated counterclockwise by an energy storage motor, force gear wheel to turn clockwise, by raising rod, compressed switching-in spring, after making gear wheel by dead-centre position by pin B and locking bolt B, stop at service position, switching-in spring energy is held.
Like this, spring mechanism of circuit breaker is exactly under initial state, the whole process that completes separating brake, combined floodgate, switching-in spring accumulation of energy that can go round and begin again.
After switching-in spring accumulation of energy completes, due to inertia, the rotor of motor can not stop the rotation immediately, and pinion can continue rotation so, drives gear wheel rotation.Because pin B and locking bolt B pin gear wheel in energy storage position, will cause so the interaction force of large pinion, pin B, locking bolt B and destroy.
Summary of the invention:
The spring operating mechanism that the object of this invention is to provide a kind of primary cut-out, it can solve the release energy all problems of carried out closing operation of switching-in spring accumulation of energy and switching-in spring, make circuit breaker for energy storage-closing operation-sub-switching operation process of spring operating mechanism requirement, obtain correctly, reliably carry out.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: it comprises gear wheel 1, pinion 2, energy storage axle 3, tooth bar 4 floats, bearing pin 5 and back-moving spring 6, pinion 2 is arranged on energy storage axle 3, in gear wheel 1 and the intermeshing portion of pinion 2, remove a part of tooth of gear wheel 1, and there is no the inner processing of the matrix grooving shape of tooth, unsteady tooth bar 4 has been installed in groove, bearing pin 5 and back-moving spring 6, this unsteady tooth bar 4 has three teeth, the parameter of tooth and gear wheel 1 identical, float tooth bar 4 under the strength of back-moving spring 6, around bearing pin 5 rotations.
One side of described energy storage axle 3 is also provided with freewheel clutch 7; in switching-in spring accumulation of energy process; the moment of torsion that comes from motor can be passed to energy storage axle 3 by reduction gearing; and in closing operation process; that cuts off energy storage axle 3 passes to reduction gearing moment of torsion; keep reduction gearing not rotate, thereby protected energy storage motor.
The present invention is after switching-in spring energy is held, because the inertia of rotor exists, pinion 2 can continue rotation, and the interactional result of tooth and tooth is to force unsteady tooth bar 4 to take bearing pin 5 to carry out back rotation as fixed axis, until motor inertia disappears, pinion 2 just can stop operating.Because having actuating force, pinion 2 do not act directly on gear wheel 1 the destruction problem having produced with regard to having solved the interaction force of large pinion, pin B, locking bolt B like this; In closing operation process, unsteady tooth bar 4 and gear wheel 1 can mesh with pinion 2 successively, the tooth bar 4 that floats can make residue fixed teeth on gear wheel 1 and pinion 2 without interrupted engagement, namely, as the engagement of normal two all gears, solved the clamping stagnation problem that the possible flank of tooth collided and then caused big or small gear operation.
The invention solves the release energy all problems of carried out closing operation of switching-in spring accumulation of energy and switching-in spring, make circuit breaker for energy storage-closing operation-sub-switching operation process of spring operating mechanism requirement, obtain correctly, reliably carry out.
