GDGK-307 Fully Automatic Circuit Breaker Analyzer Switch Dynamic Contact Resistance Tester

Product Description

GDGK-307 

Fully Automatic Circuit Breaker Analyzer Switch Dynamic Contact Resistance Tester

Mechanical characteristic testing of high-voltage circuit breakers is an indispensable part of the production, installation, and commissioning process of switches, and is of great significance for detecting and identifying the mechanical characteristics of circuit breakers. The inherent opening (closing) time, speed and travel, and the quality of the operating power supply (I-U curve of the operating winding) are important parameters for the reliable operation of high-voltage circuit breakers.


Main Features


1. The test items cover all the relevant parameter detection of the mechanical characteristics of the circuit breaker

2. A new test method to evaluate the wear status of the arc suppression contacts of the circuit breaker: Arcing contact analysis module allows users to automatically assess the degree of loss of inside Arc suppression contact of circuit breaker without disassembly.

3. The new vibration fingerprint test evaluates the state of the circuit breaker from a new perspective: The vibration fingerprint test results contain richer information of circuit breaker operation, for potential risk of failure or faulty breakers, it can locate the fault position quickly.

4. Integrated contact resistance tester function inside the instrument, reducing repeated investment

5. Envelope drawing and matching function completes the automatic evaluation of the reference mechanical stroke of the circuit breaker

6. Super data management and convenient report making functions make the test process easier

7. GDGK-307 Circuit Breaker Analyzer can measure the parameters of multi-stage circuit breakers with 4 poles in one direction at the same time

8. The vibration tests do not need to change the original line connection, so the users can complete the charged detection of mechanical characteristics of circuit breaker.

9. 12.1-inch touch screen for control and data input

10. Built-in micro printer for test result printout.

11. Generate WORD format test report automatically (all reports and data can be exported through Flash disk).


Main Test Items

1. Measurement of closing time, opening time, time spread between poles, time spread between units of one pole, bounces etc. 
2. Measurement of closing speed, opening speed and average speed.
3. Measurement of clearance between open contacts, over travel, overshoot travel and total travel.
4. Measurement of closing coil current time curve, opening coil current time curve and the maximum coil current.
5. Test travel time curve, speed time curve and acceleration time curve.
6. Measurement of pre-insertion resistance value and pre-insertion ion time.
7. Test contact resistance.
8. Measurement of dynamic resistance time curve and length for arcing contacts.
9. Vibration test, including vibration fingerprint curve acquisition, management, and vibration fingerprint curve automatic matching.
10. CO-t1-CO,O-t-CO-t1-CO,CO rated operating sequence verification test.

11. Drawing Envelopes for reference travel curve and compare travel curve with envelopes.
12. Mechanical travel curve automatic compare with saved travel curve.
13. Measurement of CO time (close-open time) and OC time (Opening-Closing time).
14. Graphite contact closing time, opening time, dynamic resistance curve measurement .

15. Zoom, editors, statistics and analysis for measurement curves.
