Paper Title:
Pattern Recognition of Typical Incipient Mechanical Failures in Circuit Breakers
  Abstract

To detect circuit breaker mechanical failures that are still in their early stages in order to avoid more serious failures and ensure reliable and safety of the grid operation, we uses a type ZW17-40.5 35 kV circuit breaker to simulate three typical incipient mechanical failures about stagnation of the energy storage spring, the dowel on the connecting rod and the moving arc. This analysis uses a digital camera detection method to record the processes for normal circuit breaker opening and closing conditions and conditions under stagnation. Additionally, by using a specially developed software to extract travel, speed and acceleration of specific location in every frame, we can discover features of the mechanical failure from the resulting data. This article provides a basis for identifying characteristics of stagnation and state monitoring of circuit breakers.
