Reasons Why The High-voltage Disconnector Mechanism Cannot Be Closed

The friction between the operating mechanism's output shaft and the combination electrical housing also affects the mechanism's transmission. Measuring the compression of the mechanism's springs generally indicates a value below the required limit. Slight variations in the isolator high voltage mechanism's frictional resistance due to normal factors such as environmental conditions and the passage of time, combined with insufficient or critical spring compression, can also contribute to the mechanism's inability to engage properly.
