Introduction:
The Circuit Breaker Test Apparatus is my company designed to meet the need of testing high-voltage
circuit breakers . It takes the ARM7 unit for core to sample,
process and then output.
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.
Main Functions of CBA-II Circuit Breaker Test Apparatus:
★ Test standard: IEC62271;
★ Closing and opening time measurement of 12 channels;
★ Max difference of closing or opening time measurement of three
phases;
★ C-O and O-C time measurement;
★ Rated operation sequence test;
★ Bounce time and frequency measurement of breaker closing;
★ Circuit breaker closing and opening speed measurement;
★ Travel-time, coil current-time curve of circuit breaker operation
measurement;
★ Travel and clearance of circuit breaker measurement;
★ Variable DC circuit breaker operation power supply;
★ Closing arc resistance value and connected time measurement;
★ Closing time and opening time of graphite circuit breaker
measurement;
★ Print test results by internal micro printers.
