HNGK-506 High Voltage Switch Dynamic Characteristic Tester Performance



1. Time: Inherent opening and closing time of 12 break contacts, simultaneity within same phase and between phases.



2. Reclosing: For each break contact, the process time of close-open, open-close, open-close-open: first opening time, first closing time, second closing time, metal short-circuit time, and no-current time values.



3. Bounce: For each break contact, closing bounce time, bounce count, bounce process, bounce waveform; opening rebound amplitude for each break contact.



4. Speed: Just-opening and just-closing speed, maximum speed, time-travel characteristic curve.



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



6. Current: Opening and closing coil current values 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 of the switch mechanical characteristic test are obtained.



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



The host can store on-site test data and has a real-time clock for archiving the test date and time.



The host features a large screen, wide temperature range, direct view, backlit LCD, and full Chinese display of all data and diagrams. 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. 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 USB drive or output to various dot matrix, laser, or inkjet printers for test reports, making on-site testing computerized.
