Huazheng HZC-4080 High-voltage Switch Characteristic Circuit Breaker Tester

1. Function

a.time：The inherent points and closing time of the 12 breaks are the same period and phase。

b.reclosing：Each break combined-point, split-close, split-close-split process time: one time, one time, two time, gold short time, no current time value.

c.bounce：Jump time, bounce times, bounce process, bounce waveform; the rebound amplitude of each break.

d.velocity：Just score, rigid speed, maximum speed, time-stroke characteristic curve.

e.route or distance of travel：Total trip, open distance, over trip, over stroke, rebound amplitude.

f.current：Division and closing current value and current waveform diagram of the split and closing coil.

d.operation voltage：DC0~270V / 20A digital adjustable circuit breaker action power supply is provided in the machine to automatically complete the low voltage action test of the circuit breaker and measure the action voltage value of the circuit breaker.

2. Characteristics

a. All models suitable for domestic and foreign production of SF6 switchgear, GIS combination of electrical, vacuum switch, oil switch mechanical properties test

b. Super anti-jamming capability, 500KV substation the bypass bus charged case can easily test to accurately measure.

c. Universal speed sensor, straight line linear sensor, rotary sensor, extremely easy to install and simple.

d. Switching operation once obtained the switch mechanical properties testing of all data and the corresponding waveform Spectrum.

e. The host field test data, the machine can be stored in the real-time clock, easy to the archive save the test date, 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 print all data and maps at any time.

h. The instrument with data analysis and management software, with PC online operation, the test results can be output to the various types of dot matrix, laser or ink-jet printer to print the test report, the field trials computerized.

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 the 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 contacts total travel before, after removing 10% each, to take the middle 80%, the ratio of the moving contact sport trip time.

e. Maximum Speed​​: Gateway process in the points (a), the moving contact sport, take the moving contact sport every 10ms for a speedometer unit until the moving contact sport stop certain speed unit value, of which the largest unit The speed value shall be the points (a) the maximum speed of the gate.

f. Just points (a) speed: different switch models depending on the measured switch factory, each manufacturer to define the different just now, just closing speed, the tester included various definitions section for The user's own choice.

  If all the above definitions are not adopted, the user can define the velocity sampling section of the rigid and rigid speed on the curve according to the time travel characteristic curve measured by the tester (the travel is directional), and the instrument automatically calculates the rigid and rigid speed defined by the user (the travel and time ratio in the sampling section).
