GDKC-6A High Voltage Circuit Breaker Tester is used to test the dynamic characteristics of high voltage circuit breaker. It is easier operation and higher accuracy than traditional device.
1. 5.7inch 640 × 480 color touch screen, high speed thermal printer which is convenient for on-site printing of test data and curves; 2. Integrated operating power, more convenient and fast for on-site use; 3. Supply voltage is 30V ~ 300V adjustable, current is 20A, continuous working time is 3s; 4. Realize three kinds of test A. Routine tests, measuring the switch opening/closing time, bounce time, the same period time; Also, measuring the speed of opening/closing, maximum speed, average speed, open distance, over travel speed; B. Re-closing test, measuring the switch re-closing time data of open/close, close/open, open/close/open; C. Low voltage test, measuring close/open coil voltage operation value, power supply voltage can be adjusted continuously; 5. Three modes of close/open brake control A. Support Inter synchronous control, inner power DC voltage ourput to close/open brake coil; B. Support External synchronous control, outer power power supply voltage to close/open brake coil; C. Support idle contact synchronous control, switch supply voltage to close/open brake coil. Inner supply two channel passive idle contacts. 6. Wave record functions, display fracture status accorded with time coordinate, like time curve, travel-Time (S-t) curve, coil current - time (I-t) curves. It is beneficial for accurate testing of failure switch. 7. Large capacity memory, Built-in USB stick or external USB stick for optional. 8. USB disk with capacity of 4G, on-site data can be mass storage, inner or external USB stick for optional. The instrument has one standard USB interface, easy to export the test data; For external USB stick, it is convenient to plug in and out. For built-in USB stick, it can connect PC directly. 9. Simultaneously test 6channel fracture, 1channel speed and 1channel current. A. Test 6channels fracture data. with inner anti-interference circuit to withstand 10kV high voltage on-site; B. Test 1channel speed. Equipped with linear sensor, angular velocity sensor, covering almost all types of switch; C. In the inner synchronous mode, it can test one channel current through close/open coil; 10. The software of PC layer can open test data, that is managing and analyzing test data, also generating test report, exporting EXCEL data etc; 11. Built-in anti-interference circuit: Can be used for 500kV substation, ensures safety of equipment and personnel. Stable, accurate test; 12. Dustproof and waterproof sealed plastic box: Dust-proof, waterproof, anti-corrosion plastic sealed box, small size, light weight, easy to carry.
