GKC-8 High Voltage Switch Mechanical Characteristics TesterDetailed product description：

The GKC-8 high-voltage switch mechanical characteristic tester is a newly designed specialized instrument for detecting the mechanical dynamic characteristics of high-voltage circuit breakers. The high-voltage switch mechanical characteristic tester adopts high-tech technology, integrating computer, printer, measurement interface circuit, and operating power supply, and is a new specialized instrument for high-voltage circuit breaker detection. Two types of displacement sensors suitable for different distances and accuracy tests are configured, and the instrument's automatic recognition system identifies the selected sensors to complete distance and speed measurement for low oil, high oil, sulfur hexafluoride, and vacuum high-voltage circuit breakers. In terms of instrument design, only one closing (opening) action is needed to sample and record all the data of six fracture surfaces, display the measurement results with a single key operation, and print the recorded measurement data. It can also print the current waveform of six fracture surfaces and the time characteristic curve of one fracture surface's moving contact. The instrument is designed strictly in accordance with the definitions in the national standards "GB 1984" and "GB 3309" for data processing.

test project
1. Time: It can measure the inherent opening and closing time, phase to phase synchronization, phase to phase synchronization, and all fracture synchronization of various switches;
2. Recloser: one-time measurement of metal short-circuit time (on/off), no current interval time (on/off), and (on/off, on/off);
3. Low voltage: The instrument comes with a DC30-250V/20A (short-term) digital adjustment operation power supply, which automatically completes the switch low voltage test;
4. Bounce: opening bounce time, closing bounce time, bounce frequency, bounce waveform chart;
5. Speed: just in and out speed, maximum speed, average speed, and draw the "travel time (S-t)" curve;
6. Travel: opening distance, overtravel, overshoot time, overshoot travel, rebound time, rebound amplitude.
