High voltage switch dynamic characteristic tester*

High voltage switch dynamic characteristic tester*

Product Features:

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.
⑶ It has automatic recognition ability and strong self-protection function for wiring errors during measurement and incorrect instructions and unsuccessful operations during operation of high-voltage circuit breakers.
⑷ The sequence of closing (opening) and the actual closing (opening) time of each circuit breaker are displayed, providing a basis for the maintenance and debugging of high-voltage circuit breakers in different phases and phases. The data related to the amount of time 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.
