GKC433M Circuit Breaker Analyzer

1. Test the mechanical and electrical characteristics of various

     high-voltage circuit breakers, isolating switches, and contactors.

2. Test parameters such as closing time, opening time, asynchronous

   time, bounce time, pre insertion time, and cooperating time for 12

     main contacts, 6 contacts with closing resistors, 6 main contacts, and

     6 auxiliary contacts.

3. Measure the pre-insert time and resistance of 6 resistor contacts.

4. The instrument interface is equipped with 12 contact status

     indicator, which facilitate the judgment of the closing and opening status

     or whether the wiring is correct.

5. There is one analog transducer input channel and one digital

     transducer input channel. Measure the stroke, penetration,

     rebound, overshoot time, overshoot, and speed of the switchgear

     using resistive transducers and digital transducers.

6. The use of digital transducers can accurately measure the rotation angle of single or multi turn operating

     mechanisms, with a measurement resolution of up to 0.05 degrees. To provide data basis for determining whether the

     switch movement is in place.

7.  Perform closing, opening, O-C-O, C-O, and O-C control.

8. Able to test the mechanical characteristics of manually operated circuit breakers.

9. Edit and store 50 switch models with various speed definitions.

10. It has the function of changing the speed definition and recalculating after the testing is completed.

11. Built in high-power adjustable DC power supply, with manual voltage adjustment knob, closing button, and

     opening button, it can quickly perform close / opening operation and action voltage testing.

12. The built-in continuous output DC power supply is used for motor energy storage.

13. It has the function of measuring motor current. By analyzing the current of the circuit breaker or isolation switch

     motor, it can be determined whether the energy storage system of the circuit breaker or the motion system of the

     isolation switch is abnormal.

14. The output control adopts electronic switches, which have high control accuracy and long service life.

15. Built-in current sensors measure the current of the closing and opening coils.

16. The instrument can store 500 sets of test data without losing data in case of power failure.

17. The stored test data can be transferred to a USB drive.

18. Use a USB flash drive to upgrade the software inside the instrument.

19. The LCD screen, which can display the operation interface, test data, contact waveform, travel curve, and current curve

     clearly both indoors and outdoors.

21. High speed thermal printers can print test data, contact waveforms, travel curves, and current curves.

22. It has the function of conducting up to 10000 automatic operation tests.

23. A USB communication cable can be used to connect the computer for operation.

24. Test data can be opened for analysis, envelope generation, and test report generation on a computer.

25. Equipped with communication interfaces, it can be equipped with external dynamic resistance measurement, both

     sides grounding test, and graphite contact testing modules (optional).

26. Support online testing of Bluetooth 2.0 and above devices, and extract internal test data from the instrument. (Optional)
