Product functions
1. Circuit breaker opening/closing time testing
Precisely measures the opening time, closing time, and three-phase synchronicity of each circuit breaker contact, quickly determining whether all contacts operate consistently.
2. Circuit breaker synchronization testing
Detects the closing and opening time differences between three-phase contacts of the circuit breaker, accurately evaluating the synchronization performance of circuit breaker operation and promptly identifying phase-to-phase non-synchronization issues.
3. Circuit breaker mechanical speed testing
Measures opening speed, closing speed, maximum speed, and speed characteristics within specific time intervals, providing a basis for assessing the operating condition of the circuit breaker's mechanical mechanism.
4. Circuit breaker travel and overtravel testing
Measures total travel, contact gap, overtravel, and rebound amplitude of the circuit breaker, comprehensively analyzing the mechanical motion state of the circuit breaker contacts.
5. Circuit breaker bounce testing
Detects contact bounce time, bounce count, and bounce amplitude during the closing process of the circuit breaker, and records bounce waveforms, helping to determine contact condition and mechanical mechanism performance.
6. Opening/closing coil current testing
Measures the operating current of the circuit breaker's opening and closing coils in real time, and displays current waveforms, used to analyze the working condition of the operating mechanism and coils.
