GDKC-6A Circuit Breaker Tester

 Features

5.7inch 640 × 480 color touch screen, high speed thermal printer which is convenient for on-site printing of test data and curves ;

Integrated operating power, more convenient and fast for on-site use;

Supply voltage is 30V ~ 300V adjustable, current is 20A, continuous working time is 3s;

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;

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.

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.

Large capacity memory, Built-in USB stick or external USB stick for optional.

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.

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;

The software of PC layer can open test data,that is managing and analyzing test data, also generating test report, exporting EXCEL data etc;

Built-in anti-interference circuit:can be used for 500kV substation, ensures safety of equipment and personnel.Stable, accurate test;

Dustproof and waterproof sealed plastic box: Dust-proof, waterproof, anti-corrosion plastic sealed box, small size, light weight, easy to carry.
