Upgraded Circuit Breaker Analyzer

This instrument is a special circuit breaker analyzer developed by our company which aims to meet the needs of various high-voltage switch operating characteristics tests. It can accurately measure the mechanical dynamic characteristics of high-voltage circuit breakers, such as oil-free, oil-rich, vacuum, sulfur hexafluoride and other mechanical dynamic parameters, and supports contact resistance meter test to comprehensively evaluate the electrical contact performance of circuit breakers. The instrument uses a large screen display, man-machine dialogue operation in Chinese, Chinese characters display the results and print out. It has the advantages of intelligence, multifunction, accurate data, strong anti-interference, simple operation, small size, light weight and nice appearance.

1.Applicable to all types of metal contact SF6 switches, GIS combination appliances, vacuum switches, oil switches at home and abroad.
2.Linear travel sensor and rotation sensor are extremely convenient and simple to install.
3..Large screen, direct and backlight LCD, electronic contrast adjustment. Chinese menu prompt, switch once, display all data and Curve graphs.
4.The main unit can store multiple groups of on-site opening and closing test results, the real-time clock inside the machine is convenient for archiving and saving the test date and time
5.Built-in fast micro printer, print all data and map.
6.The digital circuit breaker analyzer has a powerful data analysis function, which can effectively analyze various mechanical characteristics index parameters of the circuit breaker.
