01、Which contact parameters does the equipment inspect?
Integrated measurement of eight major items - contact gap, overtravel, final pressure, trip force, trip travel, holding force, contact bounce, and isolation function - which directly determine the breaking capacity and protection reliability of the circuit breaker.
02、What is the inspection accuracy?
A high-speed sampling module is adopted, with three-phase synchronization error <= +/-0.1ms (N pole closes first and opens last); contact gap / overtravel are automatically calculated and equivalently converted by the PLC, reducing manual reading errors, and the results are displayed in real time on the touch screen.
03、How are pressure and bounce measured?
A linear actuator with a pressure sensor clamps the moving contact phase by phase; the peak at the moment of separation is recorded as final pressure, and the holding force is judged simultaneously; the closing bounce time and waveform are collected in real time, and exceeding the set value results in a fail verdict.
04、How many measurements can be completed in a single clamping?
The "automatic stop-lift-position-test" line flow completes all measurements of geometric, mechanical, and dynamic parameters and isolation function verification in a single clamping, offering high efficiency and strong consistency.
05、How are non-conforming products handled?
Barcode binding + MES networking for full-process traceability; non-conforming products automatically enter the reject chute, preventing defective outflow.
06、What scenarios is it suitable for?
Suitable for 100% full inspection of the contact system, SPC data collection and continuous improvement, as well as contact system design verification and parameter calibration during the new product development stage.
