Multi functional high-voltage switch dynamic characteristic tester

Multi functional high-voltage switch dynamic characteristic tester

The testing instrument is equipped with two types of displacement sensors suitable for different distances and accuracy tests. The instrument's automatic recognition system identifies the selected sensors and completes 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 adopts highly stable components. Floating, large-area, digital filtering and other anti-interference technologies.
The instrument is equipped with two types of displacement sensors, suitable for detecting high-voltage circuit breakers with different distance, speed, and accuracy requirements. After inserting different sensors, the instrument will automatically recognize them. The instrument can automatically recognize the closing (opening) and reclosing operations of high-voltage circuit breakers, and automatically collect all kinds of data after the operation. The measurement and calculation process is automatically completed by the CPU.
The instrument has the ability to automatically identify wiring errors, incorrect instructions, and unsuccessful operations during the measurement and operation of high-voltage circuit breakers, as well as strong self-protection functions.
The instrument displays the order of closing (opening) and the actual closing (opening) time of each break, providing a basis for the maintenance and debugging of high-voltage circuit breakers in different phases and phases. The data related to time quantity is automatically not displayed and output in 0.1 milliseconds.
⑸ The instrument can measure the travel and overtravel of the moving contact by installing sensors on the fracture surface of any phase of the high-voltage circuit breaker, and can simultaneously measure and calculate the travel and overtravel data of each fracture surface of the three phases. The instrument has a measurement accuracy of 1% per second for speed.
The power box provides a 0-250V DC operating power supply to directly operate the high-voltage circuit breaker. Suitable for DC controlled operating mechanisms such as electromagnetic, hydraulic, and spring energy storage.
The instrument is small in size, light in weight, easy to operate, and portable, especially suitable for field flow detection and on-site maintenance and testing of substations. It is a tool for the production, inspection, maintenance, and commissioning of high-voltage circuit breakers.
