II Performance
Time
The machine can measure the natural parting and closing time of 12 metal fractures, the same period time, the same period time, the same period time, the gold short time, the no flow time, the closing spring time of the process of closing - parting, dividing - parting and dividing - dividing; Some models can measure the pre-casting time of closing resistance.
Speed and stroke
This tester can record and measure the closing bounce time, the number of bounces, the bounce process, and the bounce waveform of each fracture.
This tester can record and calculate the rigid points, rigidity, maximum speed, average speed, total travel, opening distance, over travel, rebound amplitude, time-travel characteristic curve.
Current and voltage
This tester can record the opening / closing current value and current waveform of the opening / closing coil, and provides DC5 ~ 270V / 10A (20A) digital adjustable circuit breaker operation power supply, automatically completes the low voltage operation test of the circuit breaker, and measures the open circuit. The operating voltage of the device.
Closing resistance
Some models of this machine can measure 6-way closing resistance value and its pre-throw time at the same time.
III Term definitions
♦ Opening / closing time: When the opening / closing coil is powered on as the timing starting point, the time to the opening / closing of the moving and static contacts.
♦ In the same period: Among the same phase, the difference between the maximum and minimum opening / closing time.
♦ Phase-to-phase synchronization: The difference between the maximum and minimum opening / closing time among three phases.
♦ Average speed: During the opening (closing) process, remove the front and back of the moving contact by 10%, take the middle 80%, the ratio of the travel of the moving contact to time.
♦ Maximum speed: During the opening (closing) process, after the moving contact starts to move, the moving contact movement is taken as a speed measurement unit every 10ms until the moving contact movement stops, and several speed unit values are obtained. The speed value is the maximum speed of opening (closing).
♦ Rigid opening / closing speed: According to the manufacturer of the switch to be tested, the switch model is different, and each manufacturer defines different rigid opening and closing speeds. This tester includes various different definitions in it. User chooses (as shown in the table below)
