Abstract
The utility model relates to a tension spring operation mechanism for a universal breaker. The tension spring operation mechanism comprises a frame, wherein the frame is provided with an operation shaft, an eccentric rod and a tension spring, the eccentric rod and the operation shaft are arranged in an eccentric mode, one end of the eccentric rod is hinged with the operation shaft through a connection rod, the other end of the eccentric rod is provided with a lever used for connecting with the breaker, a rotating axis of the lever and an axis of the operation shaft are coaxial, one end of the tension spring is mounted on the frame through a fixing shaft, the other end of the tension spring is hinged on the eccentric rod, the operation shaft is coaxially and fixedly provided with a dialing piece disc, and the dialing piece disc has at least one dialing piece which rotates to drive the eccentric rod to rotate around the operation shaft. According to the tension spring operation mechanism for the universal breaker, an original pressure spring mechanism is replaced by the tension spring mechanism, the tension spring operation mechanism has properties of simple structure, low cost and convenient operation, solves technical problems of complex structure of the operation mechanism and a large occupation space, can rapidly realize closing and opening operation and greatly improves operation reliability of the equipment.
Description
Technical field
The utility model relates to breaker technical field, especially a kind of extension spring operating mechanism for omnipotent breaker.
Background technology
In omnipotent breaker, press ring main unit operating mechanism in the time controlling the closure of power load switch and disconnect, conventionally the mode that uses lever Compress Spring to release energy, but this kind of mode is subject to the restriction in space, in the time that needs strengthen closed and speed that disconnect, the structure of stage clip just cannot meet, but also has the risk of spring doubling-up.When the work of stage clip spring structure, need guiding, number of spare parts is relatively many, requires machining accuracy high, manufacturing process complexity, and cost is high, and product reliability is difficult for guaranteeing.
Summary of the invention
The technical problems to be solved in the utility model is: overcome circuit breaker operation mechanism complex process in prior art, the technical problem that reliability is low, a kind of extension spring operating mechanism for omnipotent breaker is provided, simple in structure, realize the object of quick splitting or integrating lock, greatly improve equipment reliability of operation.
The utility model solves the technical scheme that its technical problem adopts: a kind of extension spring operating mechanism for omnipotent breaker, comprise frame, described frame is provided with operating axis, eccentric rod and extension spring, described eccentric rod and operating axis eccentric setting, one end of eccentric rod is hinged by connecting rod and operating axis, the other end is installed with the lever for connecting breaker, the pivot center of described lever and the axis coaxle of operating axis, described extension spring one end is installed in frame by fixed axis, the other end is articulated with on eccentric rod, on described operating axis, be coaxially installed with plectrum dish, on described plectrum dish, there is the plectrum that at least one drives eccentric rod to rotate around operating axis in the time rotating.
Further, on described plectrum dish, there are two plectrums.One of them drives eccentric rod to rotate when closing a floodgate, and another drives eccentric rod rotation during for separating brake.
The beneficial effects of the utility model are, extension spring operating mechanism for omnipotent breaker of the present utility model, change original stage clip structure into extension spring structure, simple in structure, cost is low, easy and simple to handle, solved existing operating mechanism complex structure, large technical problem takes up room, realize the object of quick splitting or integrating lock, greatly improve equipment reliability of operation.

In figure: 1. frame, 2. operating axis, 21. plectrum dishes, 22. plectrums, 3. eccentric rod, 31. connecting rods, 4. extension spring, 5. lever, 6. fixed axis.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1 to Figure 3, a kind of extension spring operating mechanism for omnipotent breaker of the present utility model, comprise frame 1, described frame 1 is provided with operating axis 2, eccentric rod 3 and extension spring 4, described eccentric rod 3 and operating axis 2 eccentric settings, one end of eccentric rod 3 is hinged by connecting rod 31 and operating axis 2, the other end is installed with the lever 5 for connecting breaker, the described pivot center of lever 5 and the axis coaxle of operating axis, described extension spring 4 one end are installed in frame 1 by fixed axis 6, the other end is articulated with on eccentric rod 3, on described operating axis 2, be coaxially installed with plectrum dish 21, on described plectrum dish 21, there is the plectrum 22 that at least one drives eccentric rod 3 to rotate around operating axis 2 in the time rotating.
As Fig. 3, further, on described plectrum dish 21, there are two plectrums 22.
When use, by electric driving device or manual operation, operating axis 2 is rotated, operating axis 2 drives plectrum dish 21 to rotate, plectrum 22 on plectrum dish 21 drives eccentric rod 3 to rotate around operating axis 2, stretching accumulation of energy is rotated and produced to extension spring 4 on eccentric rod 3 around fixed axis 6, in the time that the center line of extension spring 4 is crossed the center of operating axis 2, the energy abrupt release of extension spring 4, drive lever 5 fast rotational, lever 5 is connected with circuit breaker, drive circuit breaker to make corresponding combined floodgate or sub-switching operation, power load switch is closed or disconnection thereupon also.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to claim scope.
