High-voltage switch mechanical characteristics tester term definition:
â— Minute (closed) gate time: The power of the minute (closed) gate coil is used as the starting point of timing, and the time when the moving and static contacts are just divided (closed).
â— Same period: In the same phase, the difference between the maximum and minimum of the minute (closed) gate time.
â— Phase-to-phase synchronization: Among the three phases, the difference between the maximum and minimum of the minute (closed) gate time.
â— Average speed: During the division (closed) gate, 10% of the total stroke of the moving contact is removed, 80% of the middle, and the ratio of the stroke of the moving contact to the time.
◠Maximum speed: During the process of splitting (closed), after the moving contact starts to move, the movement of the moving contact is a counting unit every 10ms until the moving contact stops, and several speed unit values ​​are obtained, of which the largest unit The speed value is the maximum speed of the minute (closed) gate.
â— Just divided (combined) speed: According to the manufacturer of the switch to be tested, the switch model is different, each manufacturer defines a different speed (combined) speed
â—‹ 10ms before and after the division: IEC standard, partial oil switch and partial SF6 switch;

If the above definitions are not adopted, the user can customize the speed sampling section of the just-divided and just-integrated speed on the curve according to the time-stroke characteristic curve (the directionality of the stroke) measured by the high-voltage switch mechanical characteristic tester. The instrument automatically calculates the user-defined just-in, just-integrated speed (the ratio of travel to time in the sample segment).
High-voltage switch mechanical characteristic tester, high-voltage switch characteristic tester, high-voltage switch dynamic characteristic tester, high-voltage switch mechanical characteristic comprehensive tester
2, sensor: acceleration speed sensor, rotary speed sensor, linear stroke sensor installation is very convenient, simple.
3. Trigger mode: internal trigger, external trigger, sensor trigger. The sensor trigger mode allows for the performance test of manually split circuit breakers, such as manual split switches on poles.
4. Energy storage output: The instrument can provide DC adjustable energy storage power supply. After one-time connection, the motor can store energy at any time without reversing the line.
5, the host large screen, straight through, wide temperature with backlight LCD, contrast electronic adjustment. Complete Chinese menu prompt operation, switch action once, display all data and waveform map.
6. The host can store 1000 sets of on-site split and close test results, real-time clock in the machine, which is convenient for archiving and saving test date and time; USB interface is used for data transfer and program upgrade.
7. The high-voltage switch mechanical characteristic tester has powerful data analysis function, which can effectively analyze various index parameters of the mechanical characteristics of the circuit breaker. Built-in fast micro printer to print all data and maps.
