Performance of High-Voltage Switch Tester



Time: Inherent opening and closing times for 12 break contacts, simultaneity within the same phase and between phases.



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



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 speeds, maximum speed, and time-travel characteristic curve.



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



Current: Opening and closing coil currents, and current waveform diagrams.



Operating Voltage: Built-in DC 30~250V/20A digitally adjustable circuit breaker operating power supply, automatically completes the low-voltage operation test of the circuit breaker, and measures the operating voltage value of the circuit breaker.



Features of High-Voltage Switch Comprehensive Tester



Suitable for mechanical characteristic testing of all models of SF6 switches, GIS combined appliances, vacuum switches, and oil switches produced domestically and internationally.



Strong anti-interference capability, allowing easy testing and accurate measurement even when the bypass busbar of a 50kV substation is live.



Linear sensors and rotary sensors are extremely convenient and simple to install.



One switch operation yields all data and corresponding waveform diagrams for the mechanical characteristic test.



The host can store on-site test data, with 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, 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.



The instrument is equipped with an RS-232 interface, allowing PC connection for operation, or output to various dot matrix, laser, or inkjet printers for test reports, making on-site testing computerized.
