The KDZD high-voltage switch dynamic characteristic tester is suitable for mechanical characteristic testing of various SF6 switches, GIS composite electrical appliances, vacuum switches, and oil switches.

Performance characteristics
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: Just in and out speed, 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.

Definition of Terms
1. Same phase and same period: The difference between the opening (closing) time and the same phase.
2. Phase to phase synchronization: The difference between the opening (closing) time of the three phases.
3. Average speed: During the opening (closing) process, 10% of the total travel of the moving contact is removed from the front and back respectively,
Take the middle 80% as the ratio of the stroke of the moving contact to the time.
4. Speed: During the opening (closing) process, after the moving contact starts to move, take every 10ms of the moving contact's movement as a speed unit until the moving contact stops, and obtain several speed unit values, among which the unit speed value is the opening (closing) speed.
5. Opening (closing) speed: Depending on the manufacturer of the tested switch and the switch model, each manufacturer has defined different speeds
6. Fast opening and closing speed: This tester includes various definition sections for users to choose from.
