Double Grounded Circuit Breaker Analyzer

Double Grounded Circuit Breaker Analyzer

MOEORW-W5126KD is an industrial computer-based dynamic characteristics tester designed for fully automated mechanical property testing of high-voltage circuit breakers. It supports time, speed, travel, bounce, reclosing, coil current/resistance, and operating voltage tests for SF6 switches, GIS, vacuum switches, oil switches, overhead switches, and contactors. The instrument integrates a high-power DC power supply, multiple sensor interfaces, data storage, waveform analysis, and printing functions, suitable for factory inspection, on-site preventive testing, and hand-over testing of switchgears up to 35kV.

1. CB does not actuate during internal trigger test

• Check DC output voltage; restart after cooling if over-temperature protection is activated.o Verify CB lock is released; use unlock power supply or external trigger mode.o Check control wiring and coil circuit continuity.

2. No test data displayed after CB action

• Confirm ground wire and break wiring are correct; only one end of CB can be grounded.o Use manual closing/opening test instead of auto-test.

3. Printer feeds paper but no print content

• Reinstall thermal paper with correct side facing up.o Replace print head if damaged.

4. Abnormal waveform or inaccurate speed data

• Check sensor installation coaxiality and fixation.o Verify sensor type and speed definition match the CB model.
