Circuit Breaker Analyzer HYGK-303

Introduction
The HYGK-303 circuit breaker analyzer is our company's special_purpose instrument designed to meet the need of testing high_voltage switches . It takes the micro controller unit(MCU) as core to sample, process and then output. The main characteristic is that it's operated in Chinese. It has many advantages such as intelligence, multi-function, accurate data, strong anti-jamming, easy operation, small size, beautiful appearance, etc. It can test the switches as follows: indoors or outdoors switches with less oil or more oil, vacuum switches, SF6 switches and so on.

Major testing items and functions
1. Test 12 contacts's opening time and closing time
2. Test reclosing time
3. Test opening_simultaniety and closing_simultaniety
4. Test speed at instant of contacts touching (separating)
5. Test springing time and springing magnitude
6. Test clearance between open contacts/gaps and overtravel between them(except in testing the vacuum switches, user has to set the clearance to the instrument beforehand) .
7. Test open (close) average speed
8. Display and print the speed-distance curve
