Exploring The Reasons Why High-voltage Disconnectors Refuse To Close

Solution for the Spring Mechanism Refusal to Close in Station high voltage isolator
Based on the above analysis, we can conclude that the spring mechanism refusal to close in Station high voltage isolator switch was due to the speed and buffer curve requirements for Station hv isolator during factory testing. This resulted in the addition of a larger buffer when adjusting the opening and closing buffers. This caused the closing speed of Station hv isolator switch to be too low, and the refusal to close due to insufficient speed when Station high voltage electrical isolator passed the dead center. The refusal to close in Station isolator high voltage was not related to the quality or design of the spring itself.
