High Voltage Circuit Breaker Final Inspection Bench

Product Performance

Date:固有 opening and closing times of 12 circuit breakers, same phase and inter-phase同期.

Re Closing Switch: Time values for the closing and opening, opening and closing, and opening-closing-opening processes at each port: one-time closing, one-time opening, two-time closing, golden short time, and no current time values.

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

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

Trip Details: Total Distance, Overrun Distance, Excess Distance, Rebound Amplitude.

Electric Current: Current values and waveform diagrams for opening and closing coils of circuit breakers.

Action Voltage: The unit provides a DC 30～250V/10A digital adjustable circuit breaker action power supply, automatically completing the low-voltage action test of the circuit breaker and measuring the action voltage value of the circuit breaker.

Product 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.

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

Direct linear sensors, rotary sensors, with extremely easy and simple installation.

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

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

The main screen features large display, wide temperature range, straight-through view, backlit LCD, and full Chinese display for all data and graphs. The LCD contrast is electronically adjustable, and it has power-off memory function.

User-friendly menu operations. The instrument is equipped with an internal printer, enabling quick and convenient printing of all data and graphs at any time.

The instrument is equipped with an RS-232 interface, allowing for connection to a PC for operation and the output of test reports to various dot-matrix, laser, or inkjet printers, thereby computerizing on-site testing.
