Features of High Voltage Switch Dynamic Characteristic Tester
Product Functions
1. Time: Intrinsic opening and closing times for 12 break contacts, same-phase synchronization, and inter-phase synchronization.
2. Graphite Contacts: Parameter testing for 3 graphite contact circuits.
3. Reclosing: Close-open time (gold-plated short time) for each break, open-close time (no-current time), and open-close-open time: first opening time, first closing time, second opening time.
4. Bounce: Closing bounce time, bounce count, bounce process, and bounce waveform for each break.
5. Speed: Just-opening and just-closing speeds, maximum speed, time-stroke characteristic curve; reclosing first opening speed, first closing speed, and second opening speed.
6. Stroke: Total stroke, opening distance, overtravel, overshoot stroke, and rebound amplitude.
7. Current: Opening and closing coil current values and current waveform diagrams for opening and closing operations.
8. Operating Voltage: Built-in DC 30-270V/20A (instantaneous operation) digitally adjustable circuit breaker operating power supply, automatically performs low-voltage operation tests on circuit breakers, and measures the operating voltage value.
Product Features
1. The main unit of this graphite contact switch characteristic tester is an industrial computer.
2. Strong anti-interference capability; it can easily test and accurately measure even in 500kV substations.
3. Siemens graphite contact switch testing: accurately tests dynamic resistance waveforms, timing, and synchronization for 3 break contacts of graphite contact switches.
4. Linear stroke sensors and rotary sensors are extremely easy and convenient to install.
5. One switch operation yields
all data and corresponding waveform diagrams for mechanical characteristic tests of the switch.
6. Suitable for mechanical characteristic testing of all models of SF6 switches, GIS combined appliances, vacuum switches, and oil switches produced domestically and internationally.
7. The main unit can store 1000 sets of on-site opening and closing test results, with a built-in real-time clock for easy archiving of test dates and times.
8. This switch tester can directly use a USB drive to save and transfer data.
9. The main unit features a large screen, wide temperature range, backlit LCD, full Chinese display of all data and diagrams, electronic contrast adjustment, and power-off memory.
10. Chinese menu operation for user convenience, with a built-in printer for quick printing of all data and diagrams.
11. The instrument is equipped with an RS-232 interface for PC connection and "Circuit Breaker Data Analysis Management Software Windows Chinese Version", allowing PC operation, direct storage of test results to the hard drive, and output to various dot matrix, laser, or inkjet printers for test reports, making on-site testing computerized.
12. Analysis software has been developed for just-opening and just-closing speed definitions, allowing arbitrary analysis as needed, suitable for speed measurement of any switch model produced by any switch manufacturer domestically or internationally.
