HNGK-506 High Voltage Switch Dynamic Characteristics Tester Performance



1. Time: Inherent opening and closing time of 12 break contacts, same-phase synchronization, and inter-phase synchronization.



2. Reclosing: The process time of close-open, open-close, and open-close-open for each break contact: first open time, first close time, second close 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-open and just-close speed, maximum speed, and time-travel characteristic curve.



5. Travel: Total travel, open distance, overtravel, overshoot travel, and rebound amplitude.



6. Current: Opening and closing coil current values and current waveform diagrams.



 



HNGK-506 High Voltage Switch Dynamic Characteristics 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.



One switch operation obtains all mechanical characteristic test data and corresponding waveform diagrams.



Strong anti-interference capability allows easy testing and accurate measurement even when the bypass busbar of a 500KV substation is energized.



The host can store on-site test data and has a built-in real-time clock for convenient archiving of test date and time.



The host features a large screen, wide temperature range, direct view, backlit LCD, full Chinese display of all data and diagrams, 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 online 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 on-site testing computerized.
