Problems solved by technology
[0002] In the actual operation of power switching equipment, 70% of the faults are caused by mechanical transmission components, of which the faults caused by the operating mechanism account for the majority. The auxiliary switch of the existing operating mechanism uses a porous turntable to adjust the angle. This method is easy to produce assembly angle error, which will cause the overall linkage mechanism of the mechanism to be stuck when it is in motion. The existing operating mechanism that can adjust the closing output force is prone to change in output power, resulting in the phenomenon of jamming. The separation of the existing mechanism The position of the closing knob is not arranged in a clear and regular manner, and the on-site operation is not intuitive and clear. Based on the above defects and deficiencies, it is necessary to improve the existing technology
