II. 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)
