HNGK-506 High Voltage Switch Dynamic Characteristic Tester Performance
1. Time: Intrinsic opening and closing time of 12 break contacts, same-phase synchronization, and inter-phase synchronization.
2. Reclosing: The opening-closing, closing-opening, and closing-opening-closing process times for each break contact: first opening time, first closing time, second closing time, metal short-circuit time, and no-current time value.
3. Bounce: Closing bounce time, bounce count, bounce process, and bounce waveform for each break contact; 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, over-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 tests of various types of SF6 switches, GIS combined appliances, vacuum switches, and oil switches.
Linear and rotary sensors are extremely easy and simple to install.
With one switch operation, all data and corresponding waveform diagrams of the switch mechanical characteristic test are obtained.
Strong anti-interference capability allows easy testing and accurate measurement even when the 500KV substation bypass bus is energized.
The host can store field test data, and the built-in real-time clock facilitates archiving and saving test dates and times.
The host 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 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 connection to a PC for operation. Test results can be directly saved to a USB drive or output to various dot matrix, laser, or inkjet printers for test reports, making field testing computerized.
