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.
Features
- Time: 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.
