Abstract
The invention relates to an operating mechanism for a change-over switch, and the operating mechanism comprises an installation seat, a cover, and a transmission mechanism disposed in the installation seat and the cover. The transmission mechanism comprises a transmission motor, a driving bevel gear disposed at a speed reduction gear end of the transmission motor, two driven bevel gears which are disposed at the left and right sides of the driving bevel gear and are engaged with the driving bevel gear, and two opening/closing gears which are engaged with the driven bevel gears. The interior of a central hole of each opening/closing gear is provided with a rotating square shaft. The rotating square shafts are connected with operating handles of change-over switches buckled at two sides. When the transmission motor obtains a control signal and then starts to rotate, the transmission motor drives the driven bevel gears at two sides and the opening/closing gears to rotate in different directions, and the square shafts on the opening/closing gears drive an operating handle of two power supplies, thereby completing the switching of the two power supplies: a normally-used power supply and a standby power supply. The operating mechanism is simple and compact in structure, is small in occupied space, is stable and reliable in operation, and is an ideal operating mechanism for the dual-power automatic change-over switch.

The handle controlling switch close a floodgate, with complete conventional power supply from the separating brake that closes a floodgate, stand-by power supply from separating brake to turning of closing a floodgate
Change switching；Control that switch needs to carry out to close a floodgate under separating brake situation, the control switch of stand-by power supply is closing a floodgate when conventional power supply
When carrying out separating brake under situation, the control circuit of described permutator i.e. exports a backwards rotation signal, driving motor and axle head
Drive bevel gear counterclockwise rotate, the left side stand-by power supply driven wheel of differential being engaged with is rotated clockwise, band
The dynamic stand-by power supply folding gear being engaged with counterclockwise rotates, and the power transmission shaft on folding gear drives the control of stand-by power supply
Switch knob processed carries out separating brake, after the control of stand-by power supply switchs separating brake, due to the driven wheel of differential counter clockwise direction on right side
Continuing to rotate, drive the conventional power supply folding gear being engaged with to be rotated clockwise, the power transmission shaft on folding gear drives
The control switch knob of conventional power supply closes a floodgate, with complete stand-by power supply by the separating brake that closes a floodgate, conventional power supply by separating brake to conjunction
The conversion switching of lock.
The operating mechanism of transfer switch of above structure has the beneficial effect that
Owing to operating mechanism uses bevel gear set to carry out transmission, simple and compact for structure, stable and reliable in work, duty volume is very
Little, if this mechanism uses in controlling the switch dual power supply for miniature circuit breaker, the width of its operating mechanism is only an one pole
The width 18.6mm of chopper, can be installed between the control switch of conventional power supply and stand-by power supply easily.
