Abstract
An outdoor high-voltage vacuum breaker operating mechanism is used for operation and driving of breakers, comprising a frame, a main shaft, an energy storage motor, a spring regulating lever, a switching spring and a position switch connected with the spring regulating lever, a ratchet wheel mounted on the main shaft, a cam, a latch shaft connected with the cam, a switching half axis connected with a latch hook on the latch shaft, an output regulating lever connected with the switching half axis, a switching electromagnet and a switching hand shank. The process of the action is as follow: When the energy storage motor is powered on or the hand shank is manually turned, the main shaft is driven; then the spring regulating lever operates to enable the switching spring to store energy; meanwhile the cam on the main shaft halves the latch hook on the latch shaft and restricts the switching half axis, when the switching half axis is turned electrically or manually to release the restriction on the latch hook, the switching operation is realized. The utility model is simple in structure, suitable for miniaturization, saving space, reducing mechanical friction and promoting reliability. The utility model is universal, both electrically and manually operated, and easy in operation.
Description
Technical field
The utility model relates to the electric switch technical field, especially relates to the operation driving mechanism in the electric switch.
Background technology
Outdoor high-voltage vacuum breaker is widely used in doing in power supply and the outdoor circuit usefulness of protection and control, but the operating mechanism of power transmission and transformation industry and the employed outdoor high-voltage vacuum breaker of electric power manufacturing mostly is two pinion gear motions and finishes energy storage, breaking-closing operating both at home and abroad at present, mechanism is complicated, volume is big, makes circuit breaker be difficult to realize miniaturization; And, influence the reliability of circuit-breaker switching on-off, but also can influence mechanical useful life because many pinions can produce very big frictional force when the engagement running.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of above-mentioned prior art, provide that a kind of volume is little, compact conformation, stable performance, frictional force is little, easy and simple to handle and the outdoor high-voltage vacuum breaker operating mechanism of highly versatile, to realize the miniaturization of circuit breaker.
For achieving the above object, the technical solution adopted in the utility model is such: a kind of outdoor high-voltage vacuum breaker operating mechanism, two vertical mounting panels that are provided with that are parallel to each other are arranged, and there is the located lateral bar to support therebetween, the body frame of forming operating mechanism, main shaft, pallet axle and branch, combined floodgate semiaxis are installed between two mounting panels, main shaft stretches out mounting panel forward and connects energy storage motor, this energy storage motor is from the tool speed change gear, on it manual power shaft is housed also and main shaft links, axle head is connected to the manual handle of energy storage; Stretch out mounting panel backward and connect extension spring connecting lever, hang spring connecting lever lower link switching-in spring, hanging the spring connecting lever also links with position switch, on the main shaft of section between two mounting panels, be connected with ratchet and cam, wherein ratchet matches with ratchet on being fixed in the mounting panel inwall, and cam can contact and connect the pallet axle, and can contact connection by pallet on the axle with branch, combined floodgate semiaxis, branch, combined floodgate semiaxis stretch out mounting panel and connect branch, making electromagnet outward respectively, and branch, making electromagnet and control circuit join; The separating brake semiaxis also connects output toggle arm by rocking arm, and output toggle arm and tripping spring join; Divide in addition, the combined floodgate semiaxis also is connected with branch, the manual handle that closes a floodgate, this manual handle rotates to different directions, can finish branch or feed motion.
Its course of work is such:
Thermal energy storage process, energy storage motor drives main shaft, hangs the action of spring connecting lever, makes switching-in spring stretching energy storage, after extension spring connecting lever rotate in place, touches position switch, cuts off the electricity supply, and props up ratchet by ratchet, and energy storage is finished; In thermal energy storage process, the pallet that the main shaft overhead cam makes the pallet axle to minute, the combined floodgate semiaxis imposes restriction;
When manual, rotate the manual handle of energy storage, by the manual power shaft drive main shaft and the action of extension spring connecting lever of energy storage motor;
Making process, making electromagnet is received reclosing command, drives the combined floodgate semiaxis and rotates the constraint of releasing combined floodgate pallet, and the switching-in spring energy storage discharges, and realizes closing operation;
When manual, rotate the manual handle that closes a floodgate, drive combined floodgate semiaxis rotates to be finished;
Separating brake process, tripping electromagnet are received the separating brake instruction, drive the separating brake semiaxis and rotate the constraint of releasing separating brake pallet, and rocking arm makes output toggle arm action joining with it, drives tripping spring, finishes the separating brake process;
When manual, rotate the manual handle of separating brake, drive separating brake semiaxis rotates to be finished.
Owing to adopted technique scheme, a kind of outdoor high-voltage vacuum breaker operating mechanism of the present utility model, because of the gear motion that they need not many pinions is finished energy storage, breaking-closing operating, it is simple that mechanism becomes, save the space, help realizing miniaturization, and can reduce mechanical friction, improve reliability; Its highly versatile both can be electronic, also can be manual, and easy and simple to handle.
