Product performance
Time: The inherent opening and closing times of the 12 breaks, the same phase and the same period between phases.
Reclosing: The process time of each break - opening, opening - closing, opening - closing - opening: first opening time, first closing time, second closing time, gold short time, no current time value.
Bounce: The closing bounce time of each break, the number of bounces, the bounce process, and the bounce waveform; The rebound amplitude of the opening at each break.
Speed: Just-split and just-closed speed, maximum speed, time-stroke characteristic curve.
Travel: Total travel, opening distance, over-travel, overshoot travel, rebound amplitude.
Current: The opening and closing current values of the opening and closing coils, and the current waveform diagram.
Operating voltage: The machine provides a DC30 ~ 250V/20A digital adjustable circuit breaker operating power supply inside, automatically completing the low-voltage operating test of the circuit breaker and measuring the operating voltage value of the circuit breaker.

Product Features
It is applicable to the mechanical characteristic tests of various types of SF6 switches, GIS combined electrical apparatus, vacuum switches and oil switches produced at home and abroad.
It has strong anti-interference ability and can easily conduct tests and precise measurements even when the bypass busbar of a 500KV substation is energized.
Linear linear sensors and rotary sensors are easy and simple to install.
Once the switch operates, all the data of the mechanical characteristic test of the switch and the corresponding waveform diagrams are obtained.
The main unit can store on-site test data and has a real-time clock inside, which is convenient for archiving and saving the test date and time.
The main unit features a large screen, wide temperature range, direct transparency, backlit LCD, and full Chinese display of all data and spectra. The LCD contrast is electronically adjustable and power-off memory is available.
The Chinese menu operation is convenient to use. The instrument is equipped with a built-in printer, which can quickly print all data and spectra at any time.
The instrument is equipped with an RS-232 interface, which can be operated online with a PC. It can also output to various dot matrix, laser or inkjet printers to print test reports, making on-site tests computerized.
