China GDKC-12A High Voltage Circuit Breaker Transformer Tester

GDKC-12A High Voltage Circuit Breaker Tester Transformer Test Device

High voltage circuit breaker is one of the most important control equipment in the power system.

GDKC-12A is used to test the dynamic characteristics of high voltage circuit breaker. It is easy to operate, with high accuracy.

FeaturesTime: the open/close time, in phase synchronization, phase-to-phase synchronization of 12contacts.Reclose: close-open, open-close, open-close-open time for each contact.Bounce: Close bounce time, times, process and waveform of each contacts.Velocity: Velocity at contact touch, maximum speed, time-range characteristic curve. Travel: Total travel, open travel, over travel, travel overshoot, bounce amplitude.Current: open/close current, current waveform diagram of the open/close coil.Operation voltage: built-in DC30~250V/20A digital, adjustable power source of breaker, automatically complete LV action test of circuit breaker and measure action voltage value of circuit breaker. It is suitable to test the mechanism parameters of all types of SF6 circuit breaker, GIS combination electric equipment, vacuum circuit breaker, oil circuit breaker.Strong anti-interfere ability. It also can easily test and accurately measure even interbus is live in 500kV substation.With universal velocity sensor(optional), linear velocity sensor, rotary sensor, easy to install.only one time action to obtain all data and corresponding waveform of breaker mechanism test.Storage test data, built-in real-time clock, which is convenient to save test date and time.LCD screen display, with contrast adjustment and power-off memory.Built-in printer, to get all data and diagram at any time quickly.
