This paper studies the method of determining switch-on and switch-off time of on-line monitoring system for vacuum circuit breakers in traction substation based on engineering project. In switch-on and switch-off process, the on-line monitoring system gets displacement signal of moving contact through the guyed displacement sensor, and gets vibration signal through the piezoelectric acceleration sensor, then the signal monitored is sent to the industrial personal computer through the data acquisition unit taking DSP as the core and the communication network. After comprehensive analysis by the backstage management software in the computer, switch-on and switch-off time can be determined.

An on-line monitoring system of vacuum pressure for 35KV vacuum tube is designed in this paper. The operation principle, hardware structure and software plan are explained in details. The system can valuate the internal pressure of the vacuum tube by monitoring the static charge of the shields using electrical field sensors with rotating electrode. At the same time, the data-collecting machine and the controller are developed for long-range and on-line monitoring. The result shows that such system runs steadily and reliably. It can estimate the vacuum degree accurately laying 35cm from the vacuum tube. Besides, it is steady and anti-jamming with less-cost.
