Jiangsu Circuit Breaker Characteristics Testerstructure

The product uses a microcontroller as its core for sampling, processing, and output. Its main feature is the use of Chinese character prompts for human-machine dialogue operation, displaying results in Chinese characters and printing them out. It has the advantages of intelligence, multiple functions, accurate data, strong anti-interference ability, simple operation, small size, light weight, and beautiful appearance. It is suitable for dynamic characteristic testing of various indoor and outdoor low oil, high oil switches, vacuum switches, and sulfur hexafluoride switches.

Functional Features

2.1 Testing Function

(1) Closing (opening) sequence (12) overtravel

(2) Close (open) the switch for the longest time (13) and over travel

(3) Three phase different stages (14) rigid closing (opening) speed

(4) Same phase, different periods (15), maximum speed

Jiangsu Circuit Breaker Characteristics TesterThere are several advantages:

——Optical oscilloscope function
The instrument is divided into three channels and can simultaneously record all transition and jump processes during the A, B, and C three-phase transition processes, including the time values at which the jump points can be seen. Not affected by weather conditions, its functions are far superior to those of a light oscilloscope.
——Strong comprehensive measurement ability. Various parameters of on load tap changers can be measured in one instrument. Whether there are breakpoints, transition waveforms, transition times, transition resistances, three-phase synchronicity, etc. during the entire process of switch selection and switching.
——Comprehensive analysis of measurement results. Users can analyze the resistance values and time of each point and segment in the waveform, as well as the time of each time segment and different phases of the three-phase through the large screen LCD display screen and various functional buttons. Through screen analysis, users can understand the changes in various parameters of the three-phase switch at each moment during the switching process, and can also print, store, and view historical waveforms for analysis and comparison.
