High voltage switch mechanical characteristic testerTwo displacement sensors suitable for different distances and accuracy tests are configured on the instrument, and the selected sensors are identified by the instrument's automatic recognition system 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.
