Abstract
The utility model relates to a magnetic force mechanism for a vacuum circuit breaker, which is characterized by comprising a stand as well as a metal connecting rod, an opening coil, a closing coil and a repulsive force disk which are mounted on the stand, wherein the repulsive force disk is fixed on the metal connecting rod between the opening coil and the closing coil, a disc spring is installed on the metal connecting rod in a penetrating mode, and the outer edge of the disc spring is fixed on the stand. The utility model has the advantages that because the disc spring with the outer edge fixed on the stand is installed on the metal connecting rod, the double-stability characteristics that the disc spring has contact pressure when in a closing state and has the maintaining function when in an opening state are sufficiently utilized, and the terminal position keeping function of the mechanism can be realized without allocating a complex plunger latch mechanism or a mechanical stripping and latching device. The utility model has the advantages of simple structure, small occupation space as well as high reliability and stability.
Description
Technical field
The utility model relates to a kind of magnetic force mechanism that is used for vacuum circuit-breaker.
Background technology
At present, the spring operating mechanism that is used for vacuum circuit-breaker mainly is made up of four functional units: driving mechanism unit, stored energy mechanism unit, release unit and electric control unit.Driving mechanism is cam---the link mechanism of a coupling vacuum circuit-breaker motion and load characteristic between right plate and central dividing plate, and its output shaft is positioned at mechanism topmost.Stored energy mechanism is a two-stage gear reduction between left plate and central dividing plate, can electronic or dependent manual operation during energy storage, have anti-the reverse and mechanical clutch means.Two switching-in springs are arranged in the outside, mechanism both sides.The big I of switching-in spring power is adjusted by lower end joint hinge nut.Manually take off mouth and be integrated, directly take off mouth with release.In order to realize making vacuum interrupter reach branch, closing position, realize by helical spring, and for branch, the "on" position that keeps vacuum interrupter also needs to design latch mechanism on frame, so its complex structure, not only need to dispose a series of mechanical part and carry out transmission, and helical spring relaxation position is uncertain, and stability is low.
Summary of the invention
The purpose of this utility model just provides a kind of simple in structure, and terminal location keeps the magnetic force mechanism that is used for vacuum circuit-breaker of good stability.
Solution of the present utility model is such: include frame, rack-mounted metal connecting rod, switching winding, closing coil and repulsion dish, described repulsion dish is to be fixed on the described metal connecting rod between described switching winding and closing coil, be coated with the dish spring on described metal connecting rod, the outer of this dish spring is fixed on the described frame.
The utility model has the advantages that:
Because the installation outer is fixed on the dish spring on the frame on the metal connecting rod, making full use of the dish spring has contact pressure to take place in "on" position, the bistable behavior that the function kept is arranged at gate-dividing state, need not to dispose that complicated latch mechanism, machinery take off, locker can realize that mechanism's terminal location keeps function, simple in structure, it is little to take up room, the reliability and stability height.
Description of drawings
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
Embodiment of the present utility model includes metal connecting rod 1, dish spring 2, switching winding 3, repulsion dish 4, closing coil 5, oily buffer unit 6.
In structure shown in Figure 1, the utility model has a frame 7, switching winding 3 and closing coil 5 have been fixedly coupled in frame 7, the metal connecting rod 1 that passes switching winding 3 and closing coil 5 also is installed on frame 7, between switching winding 3 and closing coil 5, is being fixed with a repulsion dish 4 on the metal connecting rod 1.On frame 7, be positioned at the relevant position of metal connecting rod 1 lower end, an oily buffer unit 6 also is installed.Be positioned on the metal connecting rod 1 switching winding 3 above be coated with a dishful of spring 2, the outer of this dish spring 2 is fixed on the frame 7.When the utility model needs separating brake in the course of the work, metal connecting rod 1 moves upward, promptly drive repulsion dish 4 moves thereupon, install also movement therewith of dish spring 2 thereon, when metal connecting rod 1 moved to switching winding 3 position contacting, dish spring 2 was positioned at extreme position, and restriction metal connecting rod 1 continues motion, repulsion dish 4 is kept at terminal location, realize separating brake.During combined floodgate, metal connecting rod 1 moves downward, and promptly drives repulsion dish 4 and moves thereupon, installs also movement therewith of dish spring 2 thereon, and when metal connecting rod 1 moved to closing coil 5 position contacting, 2 pairs of metal connecting rods 1 of dish spring had down force pressure, realized closing function.
