High Voltage Switch Mechanical Characteristics Tester



Dary Electric recommends



1. Advanced EMC layout, with internal separation of strong and weak currents, providing superior anti-interference capability.

2. Utilizes fully imported SMT technology to ensure measurement accuracy and control the damage rate of the instrument during transportation and use.

3. Time measurement with 3-12 channels, each channel timing independently.

4. Full Chinese operation interface, with a large high-temperature resistant and anti-solar-radiation LCD display. The screen automatically shows the status of 12 break contacts and prompts the next operation.

5. The instrument automatically identifies and indicates the closing/opening status with indicator lights (non-pulse type), making operation simple and convenient.

6. The instrument comes with a 15A operating power supply with low ripple coefficient and excellent performance. Only 220V AC is needed on-site for testing.

7. *Fully automatic low-voltage test: just set a voltage value, no manual operation required.

8. High-speed thermal printer with strong storage function, saving your valuable time.

9. Overcurrent protection function: users need not worry about damaging equipment or instruments due to incorrect wiring.

10. Reclosing test: one-time measurement of metal short-circuit and no-current time.

11. Equipped with linear and angular velocity sensors, suitable for testing switches of vacuum, low oil, multi-oil, SF6, load, GIS, etc., from 6KV to 750KV. Test results can be intelligently analyzed, and data can be saved in case of power failure.

12. Internal synchronization and external synchronization: two modes to meet different requirements of DC or AC and load switches.
