HNGK-506 High Voltage Switch Dynamic Characteristic Tester Performance
1. Time: Intrinsic opening and closing times 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 opening time, first closing time, second closing time, contact touch time, and dead time.
3. Bounce: For each break contact, the closing bounce time, bounce count, bounce process, and bounce waveform; and the opening rebound amplitude for each break contact.
4. Speed: Just-opening and just-closing speeds, maximum speed, and time-travel characteristic curve.
5. Travel: Total travel, contact gap, overtravel, overshoot travel, and rebound amplitude.
6. Current: Opening and closing coil currents, and current waveform diagrams.
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 easy and convenient to install.
With one switch operation, all data and corresponding waveform diagrams for mechanical characteristic testing are obtained.
Strong anti-interference capability allows easy testing and accurate measurement even when the 500kV substation bypass bus is energized.
The main unit can store on-site test data and has a real-time clock for archiving 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, with electronic contrast adjustment and power-off memory.
Chinese menu operation for easy use. The instrument has a built-in printer for quick printing of all data and diagrams. It is equipped with a USB interface and data analysis management software, allowing PC connection for operation, direct storage of test results to a USB drive, or output to various dot matrix, laser, or inkjet printers for test reports, making on-site testing computerized.
