10KV Circuit Breaker Mechanical Characteristics Tester
DARUI Electric recommends for you
1. Time: Inherent opening and closing time of 12 break points, same-phase synchronization, inter-phase synchronization.
2. Reclosing: For each break point, the closing-opening, opening-closing, opening-closing-opening process times: one opening time, one closing time, second closing time, gold short time, no-current time value.
3. Bounce: For each break point, the closing bounce time, bounce count, bounce process, bounce waveform; opening amplitude for each break point.
4. Speed: Just-opening and just-closing speed, maximum speed, time-travel characteristic curve.
5. Travel: Total travel, opening distance, overtravel, overshoot travel, amplitude.
6. Current: Opening and closing coil current values, current waveform diagram.
