Reliability Of Gravity-assisted Mechanism In High-voltage Disconnect Switches

The transmission mechanism of high voltage isolator includes multiple components such as the operating handle, transmission linkage, and rotating shaft. The coordination of these components determines the overall motion quality of high voltage isolator switch. Under the influence of gravity, the relative motion trajectory between the moving contact and the stationary contact is more stable, and the contact opening angle and distance meet the specifications, usually not less than 160mm or the opening angle is not less than 65 degrees. This characteristic remains consistent throughout multiple separation and reassembly operations, preventing the accumulation of mechanical deviations caused by repeated actions.
