Abstract
The utility model relates to the technical field of electric power equipment, and particularly to a novel electric spring operating mechanism. An inner transmission mechanism mainly comprises a mounting frame which is used as the frame. The front end of the mounting frame is provided with a manual energy storage shaft and a motor gear. The motor gear is hinged with a secondary gear, a third gear and a main shaft. Holding ratchets are respectively mounted at the periphery of the main shaft. An output connecting lever is hinged with a switching-off buckling plate. A switching-on latch is connected with a switching-on semi-shaft. The switching-off buckling plate is connected with a switching-off semi-shaft. A terminal row is arranged outside the inner transmission mechanism. An energy storage motor is arranged at an upper gap of the mounting frame. A travel switch is arranged above the energy storage motor. An adjusting bolt is mounted behind an energy storage spring. An interlock block is hinged with a manual switching on/off shaft. An energy storage indicating shaft is arranged beside a rectifying block. A switching-on electrical apparatus release, a switching-off electrical apparatus release and an auxiliary switch are respectively arranged behind the mechanism.
Description
Technical field
The utility model relates to a kind of electric spring operation machine, is applicable to circuit breaker and the fully closed combined electric unit of high pressure and ultrahigh voltage power system.
Background technology
Existing spring operating mechanism is installed drive system between framework, drive system is by cam, roller and one-level four connecting rods are formed by connecting with pivot pin, its core is, by the setting to each part dimension parameter, adopt one-level four connecting rods to realize the function of spring operating mechanism, although described spring operating mechanism is simple in structure, but its structure itself does not have effort-saving mechanism, the main energy-storaging spring that relies on, and cam, each power arm in one-level four connecting rods drives moving contact, said structure is by increasing the elastic stiffness of energy-storaging spring, and add cam, each swing arm in one-level four connecting rods guarantees the requirement of one open-one close, and the elastic stiffness of energy-storaging spring increases, and cam, the lengthening of the each power arm in one-level four connecting rods, determine that the active force for driving energy-storaging spring accumulation of energy requires larger, and energy-storaging spring, cam, one-level four connecting rods, the material that the size of other related components all requires greatly or manufacture above-mentioned part to use has higher requirement.So above-mentioned spring operating mechanism size is bigger than normal, structure is not compact.When the operation of motor energy storage section, the noise of generation is very large, often makes mechanism's energy storage not in place, and when energy storage puts in place, dieback phenomenon easily appears in mechanism, causes mechanism normally not close a floodgate, existing energy storage motor repair and replacement inconvenience.
Summary of the invention
The noise producing when solving motor energy storage in background technology is very large, easily occurs that mechanism's energy storage is not in place, and energy storage is excessive, and mechanism can not normally close a floodgate, once energy storage motor go wrong, repair and replacement inconvenience.The technical solution of the utility model is, described electric spring operating mechanism, inner transmission mechanism mainly comprises the installation frame as frame, at the front end of installation frame, manual energy storage axle and motor gear are installed, motor gear and secondary gear, tertiary gear and main shaft are hinged, main shaft surrounding is installed respectively and is kept ratchet, output toggle arm and separating brake buckle hinged, and closing pawl is connected with combined floodgate semiaxis, and separating brake buckle is connected with separating brake semiaxis; The described outer setting at inner transmission mechanism has terminal board, in the upper indentation, there of installation frame, energy storage motor is installed, and travel switch is arranged on the top of energy storage motor, adjusting bolt be arranged on energy-stored spring after, interlock block is with manually to close split axle hinged.Energy storage indication axle is equipped with on described rectifying block side, is also separately installed with combined floodgate release, separating brake release and auxiliary switch after mechanism.
The beneficial effects of the utility model are: this spring operating mechanism overall volume is dwindled, and motor-operating mechanism has electronic or manual energy storage, electromagnetism or manually closes a point function.Motor can produce very little noise in the time of energy storage, has avoided the phenomenon of the not in place and dieback of mechanism's energy storage, facilitates motor to change.

Embodiment
Electric spring operating mechanism, inner transmission mechanism mainly comprises the installation frame as frame, at the front end of installation frame, manual storage connecting lever 23 and motor gear 20 are installed, motor gear and secondary gear 17, tertiary gear 14 and main shaft 9 are hinged, main shaft surrounding is installed respectively backstay 30, output toggle arm 33 and driving claw 19, combined floodgate draw ring 27 is connected with combined floodgate semiaxis 26, separating brake draw ring 32 is connected with separating brake semiaxis 31, the outer setting travel switch 18 of inner transmission mechanism is arranged on the top of energy storage motor, described rectifying block 29 is also separately installed with trip shaft 5 and auxiliary switch 13 below.
When energy storage, pull energy storage draw ring 25 or motor 22 is rotated, sprocket shaft 24 is rotated and drive energy storage axle sleeve 17 to rotate, switching-in spring 3 is elongated and makes mechanism's energy storage.After in spring is crossed, by backstay 30, its location is kept, mechanism is in preparing "on" position (energy storage state), while carrying out closing operation, pull combined floodgate draw ring 27 or knot closing coil 26 to apply voltage, backstay 30 rotates, removing closes a floodgate keeps switching-in spring to release energy, and 17 rotations of energy storage axle sleeve interlock rotary axle box 14 and three-phase main shaft rotate.When combined floodgate completes, rocking arm 9 fastens semiaxis 6 makes circuit breaker in "on" position.Under mechanism's "on" position, spring cross in after kept by backstay 30, and backstay 30 is fastened by interlock 8.After breaker closing, pull separating brake draw ring or motor against direction rotation, make semiaxis 6 to rotating counterclockwise, trip shaft 5 is rotated and is driven semiaxis 6 to rotate, breaker open operation.
