Why Does Operating The High-voltage Disconnect Switch Cause The Turbine To Crack?

During operation high voltage isolator, if the closing limit of the conductive rod is not properly matched with the drive motor, it may cause cracks in the turbine components. In part of high voltage isolator switch, the connection between the main drive shaft and the vertical drive shaft of the gate mechanism adopts a semi-cylindrical mating structure. When the drive motor is activated, the semi-cylindrical structure may deform and generate gap vibration, thereby transmitting mechanical impact to the turbine body.
