Performance of High-Voltage Switch Tester
Time: Inherent opening and closing time of 12 breakpoints, simultaneity within same phase and between phases.
Reclosing: Process time for each breakpoint's close-open, open-close, open-close-open: first open time, first close time, second close time, metal short-circuit 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 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: 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 appliances, vacuum switches, and oil switches produced domestically and internationally.
Strong anti-interference capability, can easily test and accurately measure even when the bypass bus of a 50kV substation is live.
Linear sensors and rotary sensors are extremely convenient and simple to install.
One switch operation obtains 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 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 PC connection for operation, or output to various dot matrix, laser, or inkjet printers for test reports, making on-site testing computerized.
