Vacuum Circuit Breaker (VCB) Break-in Test Equipment
Mechanical characteristic testing includes testing the closing and opening time of the vacuum circuit breaker; Hard opening and closing speed; Closing and opening curves, three-phase with different periodicity; Three phase travel; Bounce time, overshoot, rebound amplitude; Fracture opening distance and overtravel; Parameters such as average speed of opening and closing. The mechanical characteristics of vacuum circuit breakers will truly reflect the performance level of vacuum circuit breakers. Accurate testing should be carried out before leaving the factory to ensure that all data is correct and free of deviations. This is the key to the circuit breaker’s ability to carry the rated working current, make and break the rated short-circuit current.
