2、 Performance characteristics

2.1 Product Performance

lTime: The inherent opening and closing time of 12 fracture surfaces, in phase synchronization and phase synchronization.

lRecloser: The closing closing, opening closing, and opening closing process time for each break: the first closing time, the first closing time, the second closing time, the metal short time, and the no current time value.

lBounce: the closing bounce time, bounce frequency, bounce process, and bounce waveform of each fracture; The rebound amplitude of each break.

lSpeed: just in and out speed, high speed, time stroke characteristic curve.

lTravel: total travel, opening distance, overtravel, overshoot, rebound amplitude.

lCurrent: The opening and closing current values and waveform of the opening and closing coils.

lAction voltage: The machine provides a DC30-250V/20A digital adjustable circuit breaker action power supply, which automatically completes the low voltage action test of the circuit breaker and measures the action voltage value of the circuit breaker.

2.2 Product Features

uSF applicable to all models produced domestically and internationally6Mechanical characteristic tests for switches, GIS composite appliances, vacuum switches, and oil switches.

u*The resistance can be easily tested and measured even when the bypass busbar of a 500KV substation is live.

uLinear and rotary sensors are extremely convenient and easy to install.

uOnce the switch is activated, all data and corresponding waveform diagrams of the switch mechanical characteristic test are obtained.

uThe host can store on-site test data and has a real-time clock inside, making it easy to archive and save test dates and times.

uHost large screen, wide temperature range, direct perspective, background light LCD, full Chinese display of all data and maps, LCD contrast electronic adjustment, power-off memory.

uChinese menu operation, easy to use. The instrument has a built-in printer that can quickly print all data and graphs at any time.

uThe instrument is equipped withRS-232interfaceIt can be operated online with a PC or output to various needle, laser, or inkjet printers to print test reports, making on-site testing computerized.
