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;
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.
