HNGK-506 High Voltage Switch Dynamic Characteristic Tester Performance
1. Time: Inherent 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, and bounce waveform; the opening rebound amplitude for each break contact.
4. Speed: Just-open and just-close speeds, 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 currents, 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 convenient and simple to install.
One switch operation yields all mechanical characteristic test data and corresponding waveform diagrams.
Strong anti-interference capability; even with the 500KV substation bypass bus energized, tests can be performed easily with accurate measurements.
The host can store field test data, and the built-in real-time clock facilitates archiving of test dates and times.
The host features a large screen, wide temperature range, direct-view, backlit LCD, displaying all data and diagrams in Chinese; 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. 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, and output to various dot matrix, laser, or inkjet printers for test reports, making field testing computerized.
