Product Description 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 1. Time: The fixed open/ close time, in phase synchronization, phase-to-phase synchronization of 12contacts. 2. Re-close: close-open, open-close, open-close-open time for each contact: 3. Bounce: Bounce time, number of times, process, waveform for each contact; Break-brake rebound amplitude for each contact. 4. Velocity: Open, close speed, maximum speed, time travel diagram. 5. Travel: Full travel, open travel, over travel, travel overshoot, bounce amplitude. 6. Current: Open, close current, current waveform diagram of the open, close coil. 7. Operation voltage: Built-in DC30~250V/20A digital, adjustable breaker power source, automatically finish LV action test of circuit breaker and measure action voltage value of circuit breaker.
It is used to test the mechanical properties of all types SF6 switches, GIS combination electric equipment, vacuum switch circuit breaker, oil circuit breaker. Strong anti-interfere ability. It also can easily test and accurately measure even inter-bus 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.
