Ⅱ: Features about the Circuit Breaker Analysis Test Equipment:
1. Measure the inherent opening and closing time of 12-way metal fracture, time tolerance in same phase, time tolerance in different phase,close-open time and no flow time in process of close-open, open-close, open-close-open, closing bounce time,Some models can measure the pre-cast time of the closing resistance.
2. Record and measure the closing bounce time, bounce times, bounce process, and bounce waveform of each fracture.
3. Record and measure opening/closing speed, maximum speed, average speed, overall limit, clearance, overtravel limit switch,rebound amplitude, time-travel characteristic curve.
4. Record the opening/closing current value and current waveform of the opening/closing coil, and provides DC5-270V/10A (20A) digital adjustable circuit breaker operation power supply, automatically completes the low voltage test of the circuit breaker, and measures the operating voltage value of the device.
5. Simultaneously measure 6-way closing resistance value and its pre-casting time in some models.
