Introduction
The High-Voltage Circuit Breakers Analyzer is designed to meet the need of testing High-Voltage Circuit Breakers . It takes the ARM7 unit for core to sample, process and then output; the main characteristic is that it’s operated in alt. 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 Circuit Breakers as follows: indoors or outdoors Circuit Breakers with less oil or more oil, vacuum Circuit Breakers, SF6 Circuit Breakers and so on.
Features
1, Test standard: IEC62271
2, Closing and opening time measurement of 12 channels
3, Max difference of closing or opening time measurement of three phases
4, C-O and O-C time measurement
5, Rated operation sequence test
6, Bounce time and frequency measurement of breaker closing
7, Circuit breaker closing and opening speed measurement
8, Travel-time, Coil current-time curve of circuit breaker operation measurement
9, Travel and clearance of circuit breaker measurement
10, Variable DC circuit breaker operation power supply
11, Closing arc resistance value and connected time measurement
12, Closing time and opening time of graphite circuit breaker measurement
13, Print test results by internal micro printers
