Problems solved by technology
The single-axis operation of the isolating switch is easy to cause misoperation. In order to ensure the safety and reliability of the three-position operation of the isolating switch, it is necessary to configure an isolating operating mechanism. High, lack of in-place limit measures for isolation closing or grounding closing, which may easily lead to overshoot problems during isolation closing or grounding closing, resulting in equipment damage, which is not conducive to the stable operation of load equipment

The invention relates to a coil spring isolation operating mechanism, comprising an installation plate, a main shaft, an isolation operation shaft and a grounding operation shaft arranged on the installation plate. The front end of the coil spring is connected to the coil spring box through the mounting plate, and the main shaft extends from the coil spring box. The coil spring box and the mounting plate are fixed by the connecting plate. The other end of the coil spring is set on the coil spring box, the rear end of the main shaft is provided with a first gear, the front end of the isolation operation shaft is provided with a second gear, the front end of the grounding operation shaft is provided with a third gear, and the second gear belt There are partial gear teeth, the third gear has partial gear teeth, and the second gear and the third gear have partial gear teeth, which are arranged toward the first gear and mesh with the first gear. It has the advantages of simple structure, simple assembly, convenient operation, stable operation and high safety, and can also effectively solve the problem of overshoot during the operation of the isolating switch.
Description
technical field [0001] The invention relates to the technical field of electric equipment, in particular to a coil spring isolation operating mechanism. Background technique [0002] The isolation switch in the power distribution cabinet plays the role of connecting high-voltage incoming lines, isolating and reliably grounding. It has three working positions: the isolation switch is connected to the high-voltage incoming line, that is, the closing operation, which is used to power up the load equipment; the isolation switch is isolated, that is, the isolation switch is disconnected from the high-voltage incoming line, which is used for the power-off of the load equipment; The isolation switch is grounded, so that the load equipment is reliably grounded, and the safety of the load side and the personal safety of the staff is guaranteed. The single-axis operation of the isolating switch can easily cause misoperation. In order to ensure the safety and reliability of the three-...
