HNGK-507 High Voltage Switch Dynamic Characteristics Tester Performance
Time: Intrinsic opening and closing time of 12 break contacts, same-phase synchronization, and inter-phase synchronization.
Closing Resistance: Pre-insertion time, pre-insertion waveform, and resistance value of closing resistors for 6 break contacts.
Reclosing: For each break contact, the process times of close-open, open-close, and open-close-open: first opening time, first closing time, second closing time, metal short-circuit time, and no-current time.
Bounce: For each break contact, closing bounce time, bounce count, bounce process, bounce waveform; opening rebound amplitude for each break contact.
Speed: Just-opening and just-closing speed, maximum speed, time-travel characteristic curve.
Travel: Total travel, opening distance, overtravel, overshoot travel, rebound amplitude.
Current: Opening and closing coil current values and current waveform diagrams.
Operating Voltage: The instrument provides a built-in DC30~250V/20A digitally adjustable circuit breaker operating power supply, automatically performs low-voltage operation tests on circuit breakers, and measures the operating voltage value.
2. Features of HNGK-507 High Voltage Switch Dynamic Characteristics Tester
Suitable for mechanical characteristic testing of all models of SF6 switches, GIS combined electrical appliances, vacuum switches, and oil switches produced domestically and internationally.
Strong anti-interference capability; even with the bypass bus of a 500KV substation energized, tests can be easily conducted with accurate measurements.
Universal speed sensors, linear sensors, and rotary sensors are extremely easy and convenient to install.
One switch operation provides all data and corresponding waveform diagrams for mechanical characteristic testing.
The host can store field test data and has a built-in real-time clock for archiving test dates and times.
The host features a large screen, wide temperature range, direct-view, backlit LCD, displaying all data and diagrams in Chinese; 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 at any time.
The instrument 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.
