6. Do not operate without the instrument cover. Do not operate this product if the cover or panel has been removed.
7. Use appropriate fuses. Only use fuses that comply with the type and rating specified for this product.
8. Avoid contact with exposed circuits and live metal. Do not touch exposed contacts and parts when the product is energized.
9. Do not operate if there is a suspected fault. If you suspect the product is damaged, have it inspected by maintenance personnel and do not continue operation.
10. After testing, wait for discharge to complete before removing test leads.
Product Introduction:
It is a specialized instrument for detecting the mechanical dynamic characteristics of high-voltage circuit breakers. The High Voltage Switch Dynamic Characteristics Tester adopts high-tech technology, integrating a computer, printer, measurement interface circuit, and operating power supply into one unit. It is a new specialized instrument for high-voltage circuit breaker testing. It is equipped with two types of displacement sensors suitable for different distances and precision testing. The instrument's automatic recognition system identifies the selected sensor and completes distance and speed measurement for oil-minimum, oil-immersed, SF6, and vacuum high-voltage circuit breakers. In the instrument's design, only one close (open) operation is needed to sample and record all data from six break contacts. Measurement results can be displayed with a single key operation, and measurement data can be printed, including current waveform diagrams for six break contacts and a time characteristic curve of the moving contact for one break.
It is a universal computer-based intelligent testing instrument developed for various high-voltage switches. The high-voltage switch characteristic tester applies photoelectric pulse technology, single-chip computer technology, and reliable anti-electromagnetic radiation technology, equipped with precise and reliable speed/distance sensors. It can be used for debugging and measuring the mechanical parameters of various voltage levels of vacuum, SF6, oil-minimum, and oil-immersed high-voltage switches. The instrument is easy to wire and simple to operate. Only one close (open) operation is needed to obtain all data for close (open) operations. It can print all required data, break contact current waveforms, and moving contact motion curves for easy analysis and storage.
