II. Performance Features

Performance

Date:固有 opening and closing times of 6 circuit breakers, same phase and inter-phase synchronization.

Re-closing Circuit: The time values for each break's closing-closing, closing-opening, opening-closing-opening sequence: one closing time, one opening time, two closing times, golden short time, and no current time.

Jump Test: The closing contact bounce time, bounce count, bounce process, and bounce waveform for each contact; the opening contact bounce amplitude for each contact.

Speed: Initial and final speed, high speed, time-distance characteristic curve.

Trip: Total mileage, distance, overshoot, overdrawn distance, rebound amplitude.

Electric Current: Separate and close coil current values, current waveform diagrams.

Action Voltage: The in-built DC30～250V/20A digital adjustable circuit breaker provides the action power source, automatically completing the low-voltage action test of the circuit breaker and measuring the action voltage value.

2. Features

Mechanical characteristic tests for all models of SF6 switches, GIS integrated electrical equipment, vacuum switches, and oil switches, applicable to domestic and international production.

Superior anti-interference capability allows for easy testing and precise measurements even when the bypass bus of a 500KV substation is live.

Universal speed sensors, linear sensors, rotary sensors, with extremely easy and straightforward installation.

A single switch operation yields all the data from the switch mechanical characteristic test, along with the corresponding waveform charts.

The main unit can store field test data, featuring an internal real-time clock for easy archiving and saving of test dates and times.

The main screen features a large display, wide temperature range, direct perspective, backlit LCD, and full Chinese display of all data and graphs. The LCD contrast is electronically adjustable, and it has power-off memory function.

User-friendly menu operation. The instrument features an integrated printer for quick and convenient printing of all data and graphs at any time.

The instrument is equipped with data analysis management software, allowing for connection to a PC for operation. Test results can be output to various dot matrix, laser, or inkjet printers to print test reports, thereby computerizing on-site testing.
