HNGK-507 High Voltage Switch Dynamic Characteristic Tester Performance
Time: Inherent opening and closing time for 12 break contacts, same-phase synchronization, and inter-phase synchronization.
Closing Resistance: Pre-insertion time, pre-insertion waveform, and resistance value for 6 break contacts' closing resistors.
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, gold short time, and no-current time value.
Bounce: For each break contact, the closing bounce time, bounce count, bounce process, bounce waveform; and the opening rebound amplitude for each break contact.
Speed: Just-opening and just-closing speed, maximum speed, and time-stroke characteristic curve.
Stroke: Total stroke, opening distance, overtravel, overshoot stroke, and rebound amplitude.
Current: Opening and closing coil current values and current waveform diagrams for opening and closing operations.
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 of the circuit breaker.
2. Features of HNGK-507 High Voltage Switch Dynamic Characteristic 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, allowing easy testing and accurate measurement even when the bypass bus of a 500KV substation is live.
Universal speed sensors, linear sensors, and rotary sensors are extremely convenient and simple to install.
With one switch operation, all data and corresponding waveform diagrams of the switch mechanical characteristic test are obtained.
The host can store on-site test data, and the built-in real-time clock facilitates archiving and saving of 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. 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 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.
