GKC433M Circuit Breaker Analyzer

INSTRUCTION

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 indicators, which facilitate the judgment of the closing and opening status and check whether the wiring is correct.

5. Equipped with one analog transducer input channel and one digital transducer input channel. It can measure the stroke, penetration, rebound, overshoot time, overshoot and speed of switchgear through resistive transducers and digital transducers.

6. Digital transducers can accurately measure the rotation angle of single-turn or multi-turn operating mechanisms, with a measurement resolution up to 0.05 degrees, providing data basis for judging whether the switch operates in place.

7. Support closing, opening, O-C-O, C-O and O-C control modes.

8. Capable of testing mechanical characteristics of manually operated circuit breakers.

9. Support editing and storing 50 switch models with customized speed definitions.

10. Support speed definition modification and data recalculation after test completion.

11. Built-in high-power adjustable DC power supply, equipped with a manual voltage adjustment knob, closing button and opening button, enabling rapid closing/opening operation and operating voltage test.

12. The built-in continuously output DC power supply is applied to motor energy storage.

13. Support motor current measurement. By analyzing the motor current of circuit breakers or isolating switches, it can judge abnormal conditions of the circuit breaker energy storage system or isolating switch motion system.

14. Adopt electronic switches for output control, featuring high control accuracy and long service life.

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