Regarding The Angle Problem Of The Three-phase Turning Arm Of The High-voltage Disconnector

In some hv isolator products, the angle of the three-phase arm of the knife switch was incorrectly adjusted, resulting in inadequate opening and closing of hv isolator switch or deviation in the phase distance, thus affecting the insulation performance and operational safety of the equipment, and often causing operational hazards of high voltage electrical isolator. The root cause of the problem is mostly related to the mechanical structure coordination accuracy, assembly process control and operating specifications.
