Performance of High Voltage Switch Tester



Time: Inherent opening and closing times of 12 breakpoints, synchronization within same phase and between phases.



Reclosing: Time for close-open, open-close, open-close-open processes per breakpoint: one open time, one close time, second close time, metal short time, and no-current time values.



Bounce: Closing bounce time, bounce count, bounce process, bounce waveform for each breakpoint; opening rebound amplitude for each breakpoint.



Speed: Just-open and just-close speeds, 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: Built-in DC30~250V/20A digitally adjustable circuit breaker operating power supply, automatically completes low-voltage operation test of circuit breaker, measures operating voltage value.



Features of High Voltage Switch Comprehensive Tester



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



Strong anti-interference capability, can easily test and accurately measure even when the bypass busbar of a 500kV substation is live.



Linear displacement sensor and rotary sensor are extremely easy and convenient to install.



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



The host can store on-site test data, with built-in real-time clock for easy archiving of test date and time.



The host features a large screen, wide temperature range, direct-view, backlit LCD, all data and diagrams displayed in Chinese, 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 connection to a PC for operation, or output to various dot matrix, laser, or inkjet printers for test reports, making on-site testing computerized.
