2. Performance Characteristics
1.Performance
a. Time: 12 inherent in the fracture points, closing time, with the same period, and within the same period.
b. Reclosing: each fracture together – sub, sub – together, sub – Hopewell – sub-process time: one point, a time is the time of the two-in-gold short time, current time value.
c.Speed: just now, just closing speed, maximum speed, time – stroke characteristic curve.
d. Stroke: total trip, open distance, over-travel, the overshoot travel, rebound amplitude.
e. Current: points, closing coil points, closing current value, the current waveform diagram.
f. Operating Voltage: DC30 ~ 250V/20A digital machine adjustable breaker operation power supply, to automatically complete low voltage operation test of the breaker, measuring the value of the operating voltage of the circuit breaker.
2. Characteristics
a. All models are suitable for domestic and foreign production of SF6 switchgear, GIS combination of electrical, vacuum switch, and oil switch mechanical properties test
b.Super anti-jamming capability, 500KV substation, the bypass bus charged case can be easily tested to accurately measure.
c. Universal speed sensor, straight-line linear sensor, rotary sensor, extremely easy to install and simple.
d. Switching operation: once the switch mechanical properties testing is obtained, all data and the corresponding waveform Spectrum.
e.The host field test data can be stored in the real-time clock, easy to archive and save the test date and time.
f. Host big screen, wide temperature, direct perspective, backlight LCD Chinese display all data and maps, LCD contrast electronic adjustment, power and memory.
g. Chinese menu operation, easy to use. Instrument built-in printer, fast printing of all data and maps at any time.
h. The instrument has data analysis and management software, with PC online operation; the test results can be output to various types of dot matrix, laser, or inkjet printers to print the test report; the field trials are computerized.
3. Terminology definition
a.Points (a) Opening time: Tripping coil of the points (a) power as the starting time to move; the static contact just points (a) time.
b. The same period: the same phase being, points (a) the maximum and minimum opening time difference.
c. White year: Three-phase points (a) and the maximum and minimum opening time difference between.
d. Average speed: points (a) gate process, moving contact total travel before, after removing 10% each, to take the middle 80%, the ratio of the moving contact spot trip time.
e. Maximum Speed: Gateway process in point (a), for the moving contact, take the moving contact spot every 10ms for a speedometer unit until the moving contact sport stop certain speed unit value, of which the largest unit speed value shall be the points (a) the maximum speed of the gate.
f. Just points (a) speed: different switch models depend on the measured switch factory; each manufacturer defines the different just now, just closing speed; the tester includes various definitions section for the user’s own choice.
