HNGK-506 High Voltage Switch Dynamic Characteristic Tester Performance
1. Time: Intrinsic opening and closing time for 12 break contacts, same-phase synchronization, and inter-phase synchronization.
2. Reclosing: For each break contact, the close-open, open-close, and open-close-open process times: first open time, first close time, second close time, metal short-circuit time, and no-current time values.
3. Bounce: For each break contact, the closing bounce time, bounce count, bounce process, bounce waveform; and the opening rebound amplitude for each break contact.
4. Speed: Just-opening and just-closing speed, maximum speed, and time-travel characteristic curve.
5. Travel: Total travel, opening distance, overtravel, overshoot travel, and rebound amplitude.
6. Current: Opening and closing coil current values and current waveform diagrams for opening and closing operations.
HNGK-506 High Voltage Switch Dynamic Characteristic Tester Features
Suitable for mechanical characteristic testing of various types of SF6 switches, GIS combined appliances, vacuum switches, and oil switches.
Linear and rotary sensors are extremely convenient and simple to install.
With one switch operation, all data and corresponding waveform diagrams for the switch mechanical characteristic test are obtained.
Strong anti-interference capability allows for easy testing and precise measurement even when the bypass busbar of a 500KV substation is energized.
The main unit can store on-site test data and has a real-time clock for archiving and saving test dates and times.
The main unit features a large screen, wide temperature range, direct view, backlit LCD, and full Chinese display of all data and diagrams. The LCD contrast is electronically adjustable with power-off memory.
Chinese menu operation for user convenience. The instrument has a built-in printer for quick printing of all data and diagrams at any time. It is equipped with a USB interface and data analysis management software, allowing PC connection for operation. Test results can be directly saved to a U disk or output to various dot matrix, laser, or inkjet printers for test reports, making on-site testing computerized.
