Suitable for SF6 switches, GIS combination devices, vacuum switches, and oil switches with all types of metal contacts produced domestically and internationally.  
FEATURES
1. Adopting an industrial computer architecture, it is suitable for SF6 switches, GIS composite electrical appliances, vacuum switches, oil switches, column switches, contactors, and other types of metal contacts produced domestically and internationally.
2. Sensors: Acceleration speed sensor, rotation speed sensor, and linear travel sensor are installed very conveniently and simply. Display parameters such as three-phase speed, stroke, opening distance, and overtravel.
3. Trigger methods: internal trigger, external trigger, sensor trigger, and manual trigger. Manual triggering can perform characteristic tests on manually opened and closed circuit breakers (without opening and closing coils), such as manual opening and closing switches on poles. Sensor triggering is mainly used in places with special requirements such as switch factories.
4. Energy storage power output: The instrument can provide an adjustable energy storage power supply with a maximum starting current of 20A. After connecting the wires at once, it can automatically control the motor energy storage without reversing the wires. Attention: The starting current of the energy storage motor should be more than 10 times its rated current. It is generally suitable for on-site energy storage of 10kV vacuum switches.
5. Host large screen, direct through, wide temperature backlit LCD, contrast electronic adjustment. Complete Chinese menu prompts for operation, with one switch action displaying all data and waveform diagrams.
6. The host can store 100 sets of on-site opening and closing test results, with a real-time clock inside for easy archiving and storage of test dates and times; The USB interface is used for data transfer and program upgrade.
7. The instrument has powerful data analysis capabilities and can effectively analyze various indicators and parameters of the mechanical characteristics of circuit breakers. Built in fast micro printer to print all data and graphs.

Instrument performance:
1. Time: The inherent opening and closing time of 12 fracture surfaces, in phase synchronization and phase synchronization.  
2. Recloser: each break is closed open, open close, open close open; Gold short time, no current interval time value.
3. Bounce: the closing bounce time, bounce frequency, bounce process, and bounce waveform of each fracture; The rebound amplitude of each break.
4. Speed: initial opening and closing speed, maximum speed, time stroke characteristic curve.
5. Travel: total travel, opening distance, overtravel, overshoot travel, rebound amplitude.
6. Current: opening and closing current values, resistance values, and current waveform diagrams of the opening and closing coils.
7. Action voltage: The machine provides a DC0-270V/20A digital adjustable circuit breaker action power supply, which automatically completes the high and low voltage action tests of the circuit breaker, measures and prints the action voltage value of the circuit breaker.
