1, Performance

Time: the natural points and closing times of 12 breakpoints, the same period as the same period and the same period.

Coincidence gate: every break of the synth-minute, section-synth, section-synth-division process time: one minute time, one time, two time, gold short time, no current time value.

Jumping: the closing time of each break, the number of bouncing times, the bouncing process, the bouncing waveform; Segment bounce value for each break.

Speed: Rigid, Rigid speed, maximum speed, time-stroke characteristic curve.

Trip: Total Trip, Open Distance, Overtrip, Overrun Trip, Bounce Value.

Current: the separation and closing of the switch coil, current value, current wave map.

Action voltage: The machine provides DC 30 ~ 250V/20A digital adjustable circuit breaker action power, automatically completes the low voltage action test of the circuit breaker, and measures the action voltage value of the circuit breaker.

2, characteristics

Suitable for testing the mechanical characteristics of SF6 switches, GIS combination appliances, vacuum switches and oil switches.

Super anti-interference ability, in the case of 500 KV substation bypass bus charged, can also easily test, accurate measurement.

Universal speed sensor, straight line sensor, rotating sensor, installation is extremely convenient and simple.

All the data and the corresponding wave map are tested for the mechanical characteristics of the switch.

The host can store field test data, real-time clock in the machine, and it is convenient to archive and save the test date and time.

Host big screen, wide temperature, straight perspective, background light LCD, full Chinese display of all data and maps, LCD contrast electronic adjustment, power outage memory.

Chinese menu operation, easy to use. The instrument has a built-in printer that prints all data and maps quickly at any time.

The instrument is equipped with USB interface and data analysis management software, which can be operated online with the PC. The test results can be deposited directly into the USB disk, and can also be exported to various needle, laser or inkjet printers for printing test reports to computerize the field tests.

Definition of terms

Points(close) gate time: points(close) gate coil as the starting point of time, to the moving and static contact just points(close) time

The same period: in the same phase, the difference between the maximum(combined) gate time and the minimum.

The same period: in the three phases, the difference between the maximum(combined) gate time and the minimum.

Average speed: in the process of points(combined) Gates, 10 % of the total stroke of the moving contact is removed before and after, 80 % is taken in the middle, and the ratio of the stroke to the time of the moving contact movement.

Maximum speed: During the separation(closing) gate process, after the moving contact begins to move, take the moving contact motion every 10 MS as a speed unit, until the moving contact motion stops, and get several speed unit values. The largest unit speed value is the maximum speed of the division(combination) gate.

Rigid(combined) speed: According to the different manufacturers of the tested switch, the switch model is different. Each manufacturer defines different rigid points and rigid speeds. This tester includes various definition parts for the user to choose.
