The KDGK-F circuit breaker dynamic characteristic tester is suitable for mechanical characteristic testing of various models of SF6 switches, GIS composite appliances, vacuum switches, and oil switches.

1. Performance
Time: The inherent opening and closing time of 12 fracture surfaces, in phase synchronization and phase synchronization.
Recloser: The closing closing, opening closing, and opening closing process time for each break: the first closing time, the first closing time, the second closing time, the metal short time, and the no current time value.
Bounce: the closing bounce time, bounce frequency, bounce process, and bounce waveform of each fracture; The rebound amplitude of each break.
Speed: initial opening and closing speed, maximum speed, time stroke characteristic curve.
Travel: total travel, opening distance, overtravel, overshoot, rebound amplitude.
Current: The opening and closing current values and waveform of the opening and closing coils.
Energy storage: In the instrument's settings interface, after turning on the voltage adjustment function, the screen displays the current voltage value. Fine adjustment with up and down keys, coarse adjustment with left and right keys. After adjusting to the required voltage, keep this interface still, turn on the energy storage switch, and there will be output.
Action voltage: The machine provides a DC20-256V/15A digital adjustable circuit breaker action power supply, which automatically completes the low voltage action test of the circuit breaker and measures the action voltage value of the circuit breaker.
 
2. Characteristics
Suitable for mechanical characteristic testing of various models of SF6 switches, GIS composite appliances, vacuum switches, and oil switches produced domestically and internationally.
Super strong anti-interference ability, even when the bypass busbar of a 500KV substation is live, it can be easily tested and accurately measured.
Linear and rotary sensors, easy and simple to install.
Once the switch is activated, the data and corresponding waveform diagram of the switch mechanical characteristic test are obtained.
The host can store on-site test data and has a real-time clock inside, making it easy to archive and save test dates and times.
Host large screen, wide temperature range, direct perspective, background light LCD, Chinese display for all data and charts, LCD contrast electronic adjustment, power-off memory.
Chinese menu operation, easy to use. The instrument has a built-in printer that can quickly print all data and graphs at any time.
