RKC-308C Circuit Breaker Mechanical Characteristics Tester
Dali Electric recommends
RKC308C is a new generation high-voltage switch comprehensive tester developed by our company based on RKC-308A. It embodies advanced technology and professional design from the core to the appearance, and is currently a professional-grade product for comprehensive testing and analysis of high-voltage switch mechanical characteristics.
It is suitable for comprehensive testing and analysis of mechanical characteristics of various voltage levels and types of high-voltage circuit breakers.
Main technical parameters: RKC-308C Circuit Breaker Mechanical Characteristics Tester
1 Working power supply: AC220V±10%, 50HZ
2 Recording method: front paper change high-speed thermal printer
3 Measurement channels: 12 time channels, 2 travel channels (linear and digital channels automatically identified)
4 Built-in operating power supply: DC20V∽270V adjustable/15A (maximum up to 20A), resolution: 1V
Voltage adjustment method: manual or fully automatic electronic adjustment
5 External operating power supply: 0~250V (AC/DC automatic identification), breaking capacity 20A
6 Trigger mode: coil current or any analog/digital input channel
7 Speed customization function: arbitrarily define the starting point of speed calculation on the travel curve

Main test functions: RKC-308C Circuit Breaker Mechanical Characteristics Tester
● Time: closing/opening time (main contact/contact with closing resistor), three-phase non-simultaneity, same-phase non-simultaneity, bounce time and count, coordination time between auxiliary switch switching and main contact
● Speed: average speed, just-separating/just-closing speed, maximum speed, and average speed of any defined segment on the travel curve
● Displacement: travel, opening distance, overtravel, overtravel distance
● Reclosing: bounce time, metal short-circuit time, dead time, arbitrary setting of reclosing interval time value
● Operating voltage: arbitrary setting of operating voltage value or fully automatic low-voltage test
● Others: after one operation of the switch, comprehensive waveforms of each input signal (time, speed, travel, bounce count), peak value of circuit breaker closing/opening coil current, pulse width, etc. can be obtained
