II. Performance Features

Performance

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

Reversing Switch: The time for each opening-closing, closing-opening, closing-opening-closing process: one-time opening, one-time closing, two-time closing, golden short time, and no current time values.

Bounce: The closing bounce time, bounce count, bounce process, and bounce waveform for each circuit break; the rebound amplitude for each circuit break opening.

Speed: Initial separation and retraction speed, high speed, time-travel characteristic curve.

Trip Details: Total Distance, Starting Distance, Excess Distance, Overshoot Distance, Rebound Amplitude.

Electrical Current: Break and close coil current values, current waveform diagrams.

Action Voltage: The unit provides a DC 30～250V/20A digital adjustable circuit breaker with an action power supply, 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 switchgear, vacuum switches, and oil switches, applicable to both domestic and international production.

Exceptional anti-interference capability, allowing for easy testing and precise measurement even when the 500KV substation bypass bus is live.

Universal speed sensors, linear sensors, rotary sensors, extremely easy and straightforward to install.

A single switch operation yields all data and corresponding waveform diagrams for the switch mechanical characteristic test.

The main unit can store on-site test data, featuring an internal real-time clock for easy archiving and saving 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 retains memory after power off.

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

The instrument is equipped with data analysis management software, which can be connected to a PC for operation. Test results can be output to various dot-matrix, laser, or inkjet printers to print test reports, thereby computerizing field tests.
