1. Performance

Time: The inherent partition and closing time of 12 breaks are the same period and the same period.

Reclosure: the closing-closing, closing-closing, closing-closing-dividing process time of each break: one minute, closing-closing time, two closing time, short gold time, no current time value.

Bounce: the closing bounce time, bounce times, bounce process, bounce waveform of each break; the bounce amplitude of each break.

Speed: Rigid minute, close speed, maximum speed, time-stroke characteristic curve.

Travel: Total travel, distance, over-travel, over-stroke, rebound amplitude.

Current: opening and closing coil, closing current value and current waveform.

Action Voltage: DC30-250V/20A digital adjustable circuit breaker action power supply is provided in the machine, which automatically completes the low voltage operation test of the circuit breaker and measures the action voltage value of the circuit breaker.

2. Characteristics 

It is suitable for testing the mechanical characteristics of all types of SF6 switches, GIS combinations, vacuum switches and oil switches produced at home and abroad.

Super anti-jamming ability can be easily tested and accurately measured under the condition of live bypass buses in 500 KV substation.

Universal speed sensor, linear sensor, rotation sensor, installation is very convenient and simple.

All data and corresponding waveform maps of the mechanical characteristics test of the switch are obtained after the switch is operated once.

The host can store the field test data and the real-time clock in the machine, which is convenient for archiving and saving the test date and time.

Host large screen, wide temperature, direct perspective, background light LCD, full Chinese display all data and atlas, LCD contrast electronic adjustment, power-off memory.

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

The instrument is equipped with USB interface and data analysis and management software, which can be operated on-line with PC. The test results can be directly stored in U disk, and can also be output to various needle, laser or inkjet printers to print test reports, making the field test computerized.

3. Terminological Definition

Opening (closing) time: the opening (closing) coil is electrified as the starting point of timing, and the closing (closing) time of the dynamic and static contacts is just divided. 

Same period: In the same phase, the difference between the maximum and minimum switching time.

Interphase synchronization: In three-phase, the difference between maximum and minimum switching time.

Average speed: In the process of switching off or closing, 10% of the total travel of the movable contacts is removed before and after switching off, and 80% of the total travel of the movable contacts is taken in the middle. The ratio of the travel of the movable contacts to the time is obtained.

Maximum speed: In the process of switching on or off, after the moving contact starts to move, the moving contact is taken as a speed unit every 10 ms until the movement of the moving contact stops, and a number of speed units are obtained. The maximum unit speed value is the maximum speed of switching on or off.

Rigid minute (close) speed: According to the manufacturer of the switch under test and the type of switch, each manufacturer defines different rigid minute and close speed. This tester includes different definitions for users to choose.
