2. Performance characteristics

1. Performance

Time: The inherent opening and closing time of 12 fractures, the same phase and the same phase.

Re-closing: closing-opening, opening-closing, opening-closing-opening process time of each fracture: one minute time, one closing time,

  Two combination time, gold short time, no current time value.

Bounce: the closing bounce time of each fracture, the number of bounces, the bounce process, and the bounce waveform; the opening rebound amplitude of each fracture.

Speed: just opening and closing speed, maximum speed, time-stroke characteristic curve.

Stroke: total stroke, opening distance, overtravel, overshoot stroke, rebound amplitude.

Current: opening and closing current values and current waveforms of the opening and closing coils.

Operating voltage: The machine provides DC0~270V/20A digital adjustable circuit breaker operating power, automatically completes the low-voltage operating test of the circuit breaker, and measures the operating voltage value of the circuit breaker.

2. Features

Suitable for mechanical characteristic testing of all models of SF6 switches, GIS combination appliances, vacuum switches, and oil switches produced at home and abroad.

Super anti-interference ability, it can be easily tested and measured accurately even when the bypass bus of the 500KV substation is charged.

Universal speed sensor (optional), linear speed sensor, rotation speed sensor, extremely convenient and simple to install.

The switch operates once, and all the data of the switch mechanical characteristics test and the corresponding waveform diagram are obtained.

The host can store on-site test data, and the internal real-time clock makes it easy to archive and save test date and time.

The host has a large touch screen, wide temperature range, direct perspective, background light LCD, full Chinese display of all data and maps, and power-off memory.

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

The instrument is equipped with data analysis and management software, which can be operated online with a PC. The test results can be output to various dot matrix, laser or inkjet printers to print test reports, making on-site testing computerized. (optional)
