This paper presents a detection device for mechanical parameter and characteristic of circuit breaker. With selecting industry computer

DSP

as well as vibration sensor etc.

the data acquiring and processing system are designed. The functions of automatic surveying

displaying

saving and printing are accomplished for parameters and the process curve of circuit breaker. The device has many advantages

such as multifunction

high speed and high precision. The measurement of many mechanical parameters and characteristics of circuit breaker are integrated into one device

it simplifies the measurement process. Finally

the measuring results and the suitability of the device are analyzed.
