Abstract :On - line mechanical characteristic measurement of Voltage Vacuum Breaker (VCB) is able to provide information about me2 chanical compositions accurately when VCB is working. This device consists of an optical grating sensor system, the signal processing circuit , and a data capture and processing system that is based on a single - chip microcomputer. The optical grating sensor and sin2 gle - chip microcomputer measurement system has the advantages of high accuracy , quick speed , cheap price , and easiness for pro2 cessing the signal . This technology is fit for measurement on - line. It is has a widetised future.
Key words : VCB ; mechanical characteristic measurement ; measurement on - line ;optical guating sensor
