KJTC-IV High Voltage Switch Mechanical Characteristic Tester is a specialized instrument newly designed for detecting the mechanical dynamic characteristics of high-voltage circuit breakers. This instrument adopts high-tech technology, integrating a computer, printer, measurement interface circuit, and operating power supply into one unit, making it a new specialized instrument for high-voltage circuit breaker detection. The tester is equipped with two types of displacement sensors suitable for distance and precision testing at different ranges, and the instrument's automatic identification system recognizes the selected sensor to complete distance and speed measurement for low-oil, multi-oil, sulfur hexafluoride, and vacuum high-voltage circuit breakers. In the design of the instrument, only a close (or open) operation is needed to sample and record all data from six break contacts, and measurement results can be displayed with a single key operation. It can also print recorded measurement data, current waveform diagrams of the six break contacts, and a time characteristic curve diagram of the moving contact for one break. The instrument's design strictly follows the definitions in national standards GB 1984 and GB 3309 for data processing.
