Abstract
An operating mechanism of a load switch relates to a control mechanism of an electric switch, and is connected with a moving contact of the load switch. The operating mechanism comprises a spring; crank arms are arranged at two ends of the spring respectively; and rotating ends of the crank arms are hinged, wherein, one of the crank arms is connected with the moving contact through a movable main conductive rod. The utility model drives the moving contact to move vertically through loosening and tensioning the spring, so as to enable the moving contact and a static contact to be contacted or separated, and result in switch-on and switch-off. The utility model has the advantages of simple structure, convenient operation and high reliability, thereby ensuring the normal operation of power transmission.
Description
Technical field
The utility model relates to a kind of controlling organization of electric switch, relates in particular to a kind of operating mechanism of on-load switch.
Background technology
In the high-tension electricity transmission, the normal on-load switch that adopts carries out insulating power supply, to guarantee the reliable and safety of electric power transfer, in on-load switch, operating mechanism as control dynamic/static contact separating brake and combined floodgate is important composition parts of on-load switch, be to guarantee that can on-load switch smooth, in time close a floodgate, the key factor of separating brake, there is complex structure mostly in existing operating mechanism, unhandy defective, parts are numerous, the assembling difficulty, because complex structure, also cause the damage and the unsteadiness of mechanism easily, also be not easy to maintenance simultaneously, stayed bigger potential safety hazard.
The utility model content
The utility model is at above-mentioned defective, and purpose is to provide a kind of on-load switch operating mechanism of simple in structure, reliable operation.
The technical solution of the utility model is: the moving contact of the utility model and on-load switch links to each other, and comprises a spring, and the two ends of spring respectively are provided with a connecting lever, and the rotation end of two connecting levers forms hinged, and wherein a connecting lever is connected with moving contact by movable leading electric pole.
The utility model by the unclamping of spring, strain and drive moving up and down of moving contact, make the dynamic/static contact contact and separate, reach the result of combined floodgate, separating brake, simple in structure, easy to operate, have very high reliability, guarantee the normal operation of electric power transfer.
Description of drawings
Fig. 1 is a structural representation of the present utility model
1 is that connecting lever one, 2 is that connecting lever two, 3 is that axle, 4 is spring among the figure.
Fig. 2 is the structural representation of arc control device
5 take electric pole for moving contact, 6 as the leading factor for fixed contact, 7 among the figure.
Embodiment
The moving contact 5 of the utility model and on-load switch links to each other, and comprises a spring 4, and the two ends of spring 4 respectively are provided with a connecting lever, and the rotation end of two connecting levers forms hinged, and wherein a connecting lever is connected with moving contact 5 by movable leading electric pole 7.
Below in conjunction with accompanying drawing the utility model is described further:
The utility model is by rotating operation connecting lever 1, when operation connecting lever 1 and connecting lever 22 in line the time, at this moment the also maximization of energy storage of spring 4, simultaneously also be the dead point of spring 4 by axle 3, when by the dead point in an instant, spring 4 releases energy, driving connecting lever 22 moves downward, connecting lever 2 two drives moving contact 5 motions by leading electric pole 7, makes moving contact 5, fixed contact 6 separating brakes, otherwise then for closing a floodgate.
Claims (1)
1, the operating mechanism of on-load switch links to each other with the moving contact of on-load switch, it is characterized in that, comprise a spring, the two ends of spring respectively are provided with a connecting lever, and the rotation end of two connecting levers forms hinged, and wherein a connecting lever is connected with moving contact by movable leading electric pole.
