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

High voltage circuit breaker is one of the most important control equipment in the power system. GDKC-12A/B (GDKC-13A) is used to test the dynamic characteristics of high voltage circuit breaker. It is easy to operate, with high accuracy.

Product Features:-

● Time: the open/close time, in phase synchronization, phase-to-phase synchronization of 12contacts.
● Closing resistor: pre-switching time, pre-switching waveform and resistance of the closing resistor of 6 channels.
● Reclosure: 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 open or close, maximum speed, time-travel characteristic curve; first open, first close and second open velocity of reclosure.
● 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 DC30～300V/20A digital, adjustable power source of breaker, automatically complete LV action test of circuit breaker and measure action voltage value of circuit breaker.
● IPC for the host.
● 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 of 1000 groups, built-in real-time clock, which is convenient to save test date and time.
● LCD screen display, with contrast adjustment and power-off memory.
● Buit-in printer, to get all data and diagram at any time quickly.
● With the circuit breaker data analysis management software. It can be communicated with PC. The test results are directly stored in the hard disk, and able to output to various types of needle type, laser or inkjet printers for printing test reports, to make the field test to computerization.
● Using U disk to save and transfer data directly.
● The corresponding analysis software is compiled according to the definition of opening, closing velocity. It is suitable for speed measurement for any types of switch.
